|
Version 2.7.5 - August 31, 2012 |
|
|
|
- Adjust opencl intensity when adjusting thread count to prevent it getting |
|
pegged at a value below the minimum threads possible. |
|
- miner.h max_hashes -> int64_t |
|
- Keep the local block number in the blocks structs stored and sort them by |
|
number to guarantee we delete the oldest when ageing the block struct entries. |
|
- Use correct sdk version detection for SDK 2.7 |
|
- Revert "Pick worksize 256 with Cypress if none is specified." |
|
- Test for lagging once more in queue_request to enable work to leak to backup |
|
pools. |
|
- There is no need to try to switch pools in select_pool since the current pool |
|
is actually not affected by the choice of pool to get work from. |
|
- Only clear the pool lagging flag if we're staging work faster than we're using |
|
it. |
|
- needed flag is currently always false in queue_request. Remove it for now. |
|
- thr is always NULL going into queue_request now. |
|
|
|
|
|
Version 2.7.4 - August 23, 2012 |
|
|
|
- Perform select_pool even when not lagging to allow it to switch back if needed |
|
to the primary. |
|
- Simplify macros in output kernels avoiding apparent loops and local variables. |
|
- Carry the needed bool over the work command queue. |
|
- Move the decision to queue further work upstream before threads are spawned |
|
based on fine grained per-pool stats and increment the queued count immediately. |
|
- Track queued and staged per pool once again for future use. |
|
- OpenCL 1.0 does not have native atomic_add and extremely slow support with |
|
atom_add so detect opencl1.0 and use a non-atomic workaround. |
|
- Pools: add RollTime info to API 'stats' and 'Stats' button in miner.php |
|
|
|
|
|
Version 2.7.3 - August 22, 2012 |
|
|
|
- Minimise the number of getwork threads we generate. |
|
|
|
|
|
Version 2.7.2 - August 22, 2012 |
|
|
|
- Pick worksize 256 with Cypress if none is specified. |
|
- Give warning with sdk2.7 and phatk as well. |
|
- Whitelist sdk2.7 for diablo kernel as well. |
|
- Only keep the last 6 blocks in the uthash database to keep memory usage |
|
constant. Storing more is unhelpful anyway. |
|
- BFL Flash - always distribute source |
|
- Increase kernel versions signifying changed APIs. |
|
- BFL flash - include source in builds and more FPGA-README |
|
- Check we haven't staged work while waiting for a curl entry before proceeding. |
|
- Use atomic ops to never miss a nonce on opencl kernels, including nonce==0, |
|
also allowing us to make the output buffer smaller. |
|
- Remove compile errors/warnings and document compile/usage in FPGA-README |
|
- bitforce-firmware-flash.c by Luke-jr |
|
- Ignore the submit_fail flag when deciding whether to recruit more curls or not |
|
since we have upper bounds on how many curls can be recruited, this test is |
|
redundant and can lead to problems. |
|
- API-README update cgminer version number |
|
- API-README fix groups P: example mistake |
|
- API-README add COIN and other edits |
|
- gpu->hit should be reset on new work as well. |
|
- Do not add time to dynamic opencl calculations over a getwork. |
|
- miner.php allow 'coin' is custom pages |
|
|
|
|
|
Version 2.7.1 - August 21, 2012 |
|
|
|
- Update windows build instructions courtesy of sharky. |
|
- Increase max curls to number of mining threads + queue * 2, accounting for up |
|
and downstream comms. |
|
- Queue enough requests to get started. |
|
- There is no point trying to clone_work in get_work() any more since we clone |
|
on every get_work_thread where possible. |
|
- There is no point subtracting 1 from maxq in get_work_thread. |
|
- Only set lagging flag once there are no staged work items. |
|
- select_pool does not switch back to the primary once lagging is disabled. |
|
- miner.php allow page title to be defined in myminer.php |
|
- Free work before retrying in get_work_thread. |
|
- Increment total work counter under mutex lock. |
|
- Increment the queued count after the curl is popped in case there's a delay |
|
waiting on curls and we think we've queued work when in fact we're waiting |
|
- API new command 'coin' with mining information |
|
- Do the dynamic timing in opencl code over a single pass through scanhash to |
|
make sure we're only getting opencl times contributing to the measured inte |
|
- Increase curl reaping time to 5 minutes since comms between curl requests can |
|
be 2 mins apart with lots of rolltime. |
|
- No need for extra variable in hash_push. |
|
- Remove short options -r and -R to allow them to be reused and remove readme |
|
entries for deprecated options. |
|
- Avoid attempting to recursively lock the console mutex by disabling warnings |
|
in gpu_fanpercent when fanspeed monitoring fails on windows. Debugged by l |
|
- Deprecate the opt_fail_pause parameter, leaving a null placeholder for |
|
existing configurations. |
|
- Don't pause after failed getwork, set lagging flag and reassess. |
|
- Add message to share if it's a resubmit. |
|
- We should not be pausing in trying to resubmit shares. |
|
- Get rid of the extending fail pause on failed connects since we discard work |
|
after a period. |
|
- get_work always returns true so turn it into a void function. |
|
- get_work never returns false so get rid of fail pause loop. |
|
- Get rid of pause and retry from get_upstream_work so we only do it from one |
|
place. |
|
- Deprecate the opt_retries feature as no one wants cgminer to automatically |
|
abort. Leave a null placeholder for configurations that still have it. |
|
- Reinstate fix ADL gpu-map not working when there are more ADL devices than |
|
openCL patch by Nite69. Add virtual adl mapping for when none is specified o |
|
- miner.php show summary Diff1 Shares total |
|
- miner.php fix Work Utility totals |
|
- miner.php format new Work Utility and Diff1 Shares |
|
- API V1.17 show Work Utility and Diff1 Shares |
|
|
|
|
|
|
|
Version 2.7.0 - August 18, 2012 |
|
|
|
- Introduce a new statistic, Work Utility, which is the number of difficulty 1 |
|
shares solved per minute. This is useful for measuring a relative rate of work |
|
that is independent of reject rate and target difficulty. |
|
- Implement a new pool strategy, BALANCE, which monitors work performed per pool |
|
as a rolling average every 10 minutes to try and distribute work evenly over all |
|
the pools. Do this by monitoring diff1 solutions to allow different difficulty |
|
target pools to be treated equally, along with solo mining. Update the |
|
documentation to describe this strategy and more accurately describe the |
|
load-balance one. |
|
- Getwork fail was not being detected. Remove a vast amount of unused variables |
|
and functions used in the old queue request mechanism and redefine the getfail |
|
testing. |
|
- Don't try to start devices that don't support scrypt when scrypt mining. |
|
- 0 is a valid return value for read so only break out if read returns -1. |
|
- Consider us lagging only once our queue is almost full and no staged work. |
|
- Simplify the enough work algorithm dramatically. |
|
- Only queue from backup pools once we have nothing staged. |
|
- Don't keep queueing work indefinitely if we're in opt failover mode. |
|
- Make sure we don't opt out of queueing more work if all the queued work is |
|
from one pool. |
|
- Set lagging flag if we're on the last of our staged items. |
|
- Reinstate clone on grabbing work. |
|
- Grab clones from hashlist wherever possible first. |
|
- Cull all the early queue requests since we request every time work is popped |
|
now. |
|
- Keep track of staged rollable work item counts to speed up clone_available. |
|
- Make expiry on should_roll to 2/3 time instead of share duration since some |
|
hardware will have very fast share times. |
|
- Do the cheaper comparison first. |
|
- Check that we'll get 1 shares' worth of work time by rolling before saying we |
|
should roll the work. |
|
- Simplify all those total_secs usages by initialising it to 1 second. |
|
- Overlap queued decrementing with staged incrementing. |
|
- Artificially set the pool lagging flag on pool switch in failover only mode as |
|
well. |
|
- Artificially set the pool lagging flag on work restart to avoid messages about |
|
slow pools after every longpoll. |
|
- Factor in opt_queue value into enough work queued or staged. |
|
- Roll work whenever we can on getwork. |
|
- Queue requests for getwork regardless and test whether we should send for a |
|
getwork from the getwork thread itself. |
|
- Get rid of age_work(). |
|
- 0 is a valid return value for read so only break out if read returns -1. |
|
- Offset libusb reads/writes by length written as well in ztex. |
|
- Cope with timeouts and partial reads in ztex code. |
|
- fpga serial I/O extra debug (disabled by default) |
|
|
|
|
|
Version 2.6.5 - August 15, 2012 |
|
|
|
- Don't try to get bitforce temperature if we're polling for a result to |
|
minimise the chance of interleaved responses. |
|
- Set memory clock based on memdiff if present from with engine changes, |
|
allowing it to parallel manual changes from the menu as well. |
|
- Increase the timeout on bitforce as per Paul Sheppard's suggestion to account |
|
for throttling + work time + excess. |
|
- Fix ADL gpu-map not working when there are more ADL devices than openCL. |
|
Initial patch supplied by Nite69. Modified to suit. |
|
- Windows' timer resolution is limited to 15ms accuracy. This was breaking |
|
dynamic intensity since it tries to measure below this. Since we are repeatedly |
|
sampling similar timeframes, we can average the gpu_us result over 5 different |
|
values to get very fine precision. |
|
- Fix harmless unused warnings in scrypt.h. |
|
- api.c typo |
|
- API allow display/change failover-only setting |
|
- Check we are not lagging as well as there is enough work in getwork. |
|
- Minimise locking and unlocking when getting counts by reusing shared mutex |
|
lock functions. |
|
- Avoid getting more work if by the time the getwork thread is spawned we find |
|
ourselves with enough work. |
|
- The bitforce buffer is cleared and hw error count incremented on return from a |
|
failed send_work already so no need to do it within the send_work function. |
|
- miner.php allow a custom page section to select all fields with '*' - e.g. to |
|
create a STATS section on a custom page |
|
- Escape " and \ when writing json config file |
|
- miner.php optional single rig totals (on by default) |
|
|
|
|
|
Version 2.6.4 - August 7, 2012 |
|
|
|
- Convert the serial autodetect functions to use int instead of char to |
|
enumerate devices. |
|
- Make the serial open timeout for BFL generically 1 second on windows. |
|
- Deuglify windows autodetect code for BFL. |
|
- There is no point zeroing temperature in BFL if we fail to get a response, and |
|
we should register it as a HW error, suggesting throttling. |
|
- Update SCRYPT README with information about HW errors. |
|
- Use the scrypt CPU code to confirm results from OCL code, and mark failures as |
|
HW errors, making it easier to tune scrypt parameters. |
|
- We may as well leave one curl still available per pool instead of reaping the |
|
last one. |
|
- Need to recheck the pool->curls count on regaining the pool lock after the |
|
pthread conditional wait returns. |
|
- Display reaped debug message outside mutex lock to avoid recursive locking. |
|
- Add specific information when ADL detects error -10 saying the device is not |
|
enabled. |
|
- api.c update API start message and include port number |
|
- miner.php ignore arg when readonly |
|
- miner.php allow pool inputs: delete, addpool, poolpriority |
|
|
|
|
|
Version 2.6.3 - August 5, 2012 |
|
|
|
- Count likely throttling episodes on bitforce devices as hardware errors. |
|
- Style cleanups. |
|
- Use FTD2XX.DLL on Windows to autodetect BitFORCE SHA256 devices. |
|
- Make pool_disabled the first in the enums == 0, fixing the pool enabled count |
|
which compares if value is not enabled before enabling it. |
|
- Correct writing of scrypt parameters to config file based on command line |
|
parameters only. |
|
- Use different variables for command line specified lookup gap and thread |
|
concurrency to differentiate user defined versus auto chosen values. |
|
- Queue a request on pool switch in case we have no work from the new pool yet. |
|
- Display failover only mode in pool menu and allow it to be toggled live. |
|
- Reinstate check for system queueing lag when the current pool's queue is maxed |
|
out, there is no staged work, and the work is needed now. |
|
- There is no need for pool active testing to be mandatory any more with queue |
|
request changes. |
|
- Fix harmless warnings. |
|
- Check the current staged and global queued as well before queueing requests. |
|
Discard stales before ageing work in the watchdog thread. Queue requests after |
|
discarding and ageing work in watchdog thread. Display accurate global queued in |
|
curses output. Reuse variable in age_work(). |
|
- The queueing mechanism has become a complex state machine that is no longer |
|
predictable. Rewrite it from scratch watching only current queues in flight and |
|
staged work available on a pool by pool basis. |
|
- API remove unused warning in non-GPU compile |
|
- api.c in linux allow to open a closed socket in TIME_WAIT |
|
- Queue an extra request whenever staged work drops below mining thread count in |
|
hash_pop. |
|
- Update debian package configs to v2.6.2 |
|
|
|
|
|
Version 2.6.2 - August 3, 2012 |
|
|
|
- Scrypt mining does not support block testing yet so don't try to print it. |
|
- Clear the bitforce buffer whenever we get an unexpected result as it has |
|
likely throttled and we are getting cached responses out of order, and use the |
|
temperature monitoring as a kind of watchdog to flush unexpected results. |
|
- It is not critical getting the temperature response in bitforce so don't |
|
mandatorily wait on the mutex lock. |
|
- Check there is a cutoff temp actually set in bitforce before using it as a cut |
|
off value otherwise it may think it's set to zero degrees. |
|
- We dropped the temporary stopping of curl recruiting on submit_fail by |
|
mistake, reinstate it. |
|
- Make threads report in either side of the scanhash function in case we miss |
|
reporting in when restarting work. |
|
- Don't make mandatory work and its clones last forever. |
|
- Make test work for pool_active mandatory work items to smooth out staged work |
|
counts when in failover-only mode. |
|
- Add debugging output when work is found stale as to why. |
|
- Print the 3 parameters that are passed to applog for a debug line in |
|
bitforce.c |
|
- Clear bitforce buffer on init as previously. |
|
- Add some headroom to the number of curls available per pool to allow for |
|
longpoll and sendwork curls. |
|
- Revert "Revert "Change BFL driver thread initialising to a constant 100ms |
|
delay between devices instead of a random arrangement."" |
|
- Revert "Remove bitforce_thread_init" |
|
- Show the correct base units on GPU summary. |
|
- Differentiate between the send return value being a bool and the get return |
|
value when managing them in bitforce scanhash. |
|
- 23a8c60 Revert "bitforce: Skip out of sending work if work restart requested" |
|
|
|
|
|
Version 2.6.1 - July 30, 2012 |
|
|
|
- Display scrypt as being built in as well. |
|
- Fix build warning about KL_SCRYPT when built without scrypt support. |
|
- Remove the low hash count determinant of hardware being sick. A low hash rate |
|
can be for poor network connectivity or scrypt mining, neither of which are due |
|
to a sick device. |
|
- api.c poolpriority changes |
|
|
|
|
|
Version 2.6.0 - July 29, 2012 |
|
|
|
- Display kilohash when suitable, but store the global mhash value still truly |
|
in megahashes to not break the API output. |
|
- Don't try and print curses output for devices that won't fit on the screen. |
|
- Add scrypt documentation in the form of a separate readme. |
|
- Fix build error without scrypt enabled. |
|
- Limit total number of curls recruited per pool to the number of mining threads |
|
to prevent blasting the network when we only have one pool to talk to. |
|
- bitforce: Skip out of sending work if work restart requested |
|
- Keep a counter of enabled pools and use that instead of iterating over the |
|
pool list. Use that value to ensure we don't set the last remaining active pool |
|
to the rejecting state. |
|
- fpgautils: add support for 57.6 kBd serial |
|
- miner.php add a socket RCV timeout for if cgminer is hung and the API thread |
|
is still running |
|
- Limit thread concurrency for scrypt to 5xshaders if shaders is specified. |
|
- Simplify repeated use of gpus[gpu]. in ocl.c |
|
- Find the nearest power of 2 maximum alloc size for the scrypt buffer that can |
|
successfully be allocated and is large enough to accomodate the thread |
|
concurrency chosen, thus mapping it to an intensity. |
|
- Don't make opt_scrypt mandatory blocking with opencl code. |
|
- Update kernel versions reflecting changes in the API. |
|
- Make the thread concurrency and lookup gap options hidden on the command line |
|
and autotune parameters with a newly parsed --shaders option. |
|
- Fix target testing with scrypt kernel as it would have been missing shares |
|
below target. |
|
- Bugfix: Use a mutex to control non-curses output |
|
- Simplify code to a single vprintf path for curses-less printing |
|
- Move opt_quiet check to my_log_curses, so it works for curses-less builds |
|
- Use log_generic for vapplog to cut down on code duplication |
|
- Add space to log output now that there is more screen real estate available. |
|
- BFL force all code to timeout to avoid hanging |
|
- Bugfix: Copy argv[0] given to dirname() |
|
- Always create the largest possible padbuffer for scrypt kernels even if not |
|
needed for thread_concurrency, giving us some headroom for intensity levels. |
|
- Use the detected maximum allocable memory on a GPU to determine the optimal |
|
scrypt settings when lookup_gap and thread_concurrency parameters are not given. |
|
- Check the maximum allocable memory size per opencl device. |
|
- Add debugging output if buffer allocation fails for scrypt and round up |
|
bufsize to a multiple of 256. |
|
- Nonce testing for btc got screwed up, leading to no accepted shares. Fix it. |
|
- Display size of scrypt buffer used in debug. |
|
- Allow intensities up to 20 if scrypt is compiled in. |
|
- Add name to scrypt kernel copyright. |
|
- Allow lookup gap and thread concurrency to be passed per device and store |
|
details in kernel binary filename. |
|
- Ignore negative intensities for scrypt. |
|
- Change the scale of intensity for scrypt kernel and fix a build warning. |
|
- Correct target value passed to scrypt kernel. |
|
- Use 256 output slots for kernels to allow 1 for each worksize. |
|
- Test the target in the actual scrypt kernel itself saving further |
|
calculations. |
|
- Reinstate GPU only opencl device detection. |
|
- Decrease lookup gap to 1. Does not seem to help in any way being 2. |
|
- Fix build. |
|
- Make pad0 and pad1 local variable in scrypt kernel. |
|
- Constify input variable in scrypt kernel. |
|
- Send correct values to scrypt kernel to get it finally working. |
|
- Create command queue before compiling program in opencl. |
|
- Detach pthread from within the api thread in case it is terminated due to not |
|
being instantiated before pthread_cancel is called from main, leading to a |
|
segfault. |
|
- Debug output per thread hashrate is out by a factor of 1000. |
|
- Initialise mdplatform. |
|
- Find the gpu platform with the most devices and use that if no platform option |
|
is passed. |

|
- Fix external scrypt algo missing. |
|
- Limit scrypt to 1 vector. |
|
- Handle KL_SCRYPT in config write. |
|
- Get rid of stuff. |
|
- Don't enqueuewrite buffer at all for pad8 and pass work details around for |
|
scrypt in dev_blk. |
|
- Set the correct data for cldata and prepare for pad8 fixes. |
|
- Bugfix: Fix build without curses but with OpenCL |

|
is passed. |
|
- Allow more platforms to be probed if first does not return GPUs. |

- Start with smaller amount of hashes in cpu mining to enable scrypt to return |
|
today sometime. |
|
- Show Khash hashrates when scrypt is in use. |
|

|
sick since they can't be. Prepare for khash hash rates in display. |
|
- Add cpumining capability for scrypt. |
|
- Set scrypt settings and buffer size in ocl.c code to be future modifiable. |
|
- Cope with when we cannot set intensity low enough to meet dynamic interval by |
|
inducing a forced sleep. |
|
- Make dynamic and scrypt opencl calls blocking. |
|
- Calculate midstate in separate function and remove likely/unlikely macros |
|
since they're dependent on pools, not code design. |
|
- bitforce: Use "full work" vs "nonce range" for kernel name |
|
- Display in debug mode when we're making the midstate locally. |
|

- Enable completely compiling scrypt out. |
|
- Begin import of scrypt opencl kernel from reaper. |
|
- bitforce_get_result returns -1 on error now. |

|
|
Version 2.5.0 - July 6, 2012 |
|
|
|
- Fix --benchmark not working since the dynamic addition of pools and pool |
|
stats. |
|
- Make disabling BFL nonce range support a warning since it has to be explicitly |
|
enabled on the command line now. |
|
- miner.php allow renaming table headers |
|
- Make bitforce nonce range support a command line option --bfl-range since |
|
enabling it decrease hashrate by 1%. |
|
- Add sanity checking to make sure we don't make sleep_ms less than 0 in |
|
bitforce. |
|
- The fastest minirig devices need a significantly smaller starting sleep time. |
|
- Use a much shorter initial sleep time to account for faster devices and nonce |
|
range working, and increase it if nonce range fails to work. |
|
- Use nmsleep instead of usleep in bitforce. |
|
- Provide a ms based sleep function that uses nanosleep to avoid the inaccuracy |
|
of usleep on SMP systems. |
|
- delay_time_ms is always set so need not be initialised in bitforce. |
|
- Increase bitforce timeout to 10 seconds. |
|
- Add more hysteresis and poll ~5 times to allow for timer delays in bitforce |
|
devices. |
|
- miner.php allow alternating line colours (off by default) |
|
- Display the actual duration of wait when it is greater than the cutoff. |
|
- Set nonce to maximum once we determine nonce range support is broken. |
|
- Initial wait time is always known so no need to zero it beforehand in |
|
bitforce. |
|
- No point counting wait time until the work is actually sent to bitforce |
|
devices. |
|
- Use string comparison functions instead of explicit comparisons. |
|
- Account for wait_ms time when nonce_range is in use on BFL. |
|
- Split nonces up into 1/5 chunks when nonce range is supported. |
|
- limit clear buffer iterations. |
|
- Ad fd check to clear buffer. |
|
- miner.php remove incorrect 'DATE' error message |
|
- miner.php allow summary header in custom pages |
|
- Disable nonce range support in BFL when broken support is detected. |
|
- Restart_wait is only called with a ms value so incorporate that into the |
|
function. |
|
- Only try to adjust dev width when curses is built in. |
|
- miner.php define custom sum fields as a simple array |
|
- Fix off-by-one error in nonce increment in bfl. |
|
- Use BE when setting nonce in bitforce nonce range work. |
|
- Enable nonce range in the normal init sequence for bfl. |
|
- Queue extra work at 2/3 differently depending on whether we're using nonce |
|
range or not. |
|
- Initially enable support for nonce range support on bfl, splitting nonces up |
|
into 3/4 size and only disable it if it fails on work submit. |
|
- Attempt to detect nonce range support in BFL by sending work requring its |
|
support. |
|
- Limit retrying on busy for up to BITFORCE_TIMEOUT_MS |
|
- Attempt to initialise while bitforce device returns BUSY. |
|
- Extend length of string that can be passed to BFL devices. |
|
- Fix signedness warning. |
|
- Adjust device width column to be consistent. |
|
- Use cgpu-> not gpus[] in watchdog thread. |
|
- Add api stats (sleep time) |
|
- Timing tweaks Added long and short timeouts, short for detecting throttling, |
|
long to give up totally. Reset sleep time when device re-initialised Still check |
|
results after timeout Back up a larger time if result on first poll. |
|
- Add API Notify counter 'Comms Error' |
|
- Style police on api.c |
|
- Do all logging outside of the bitforce mutex locking to avoid deadlocks. |
|
- Remove applog call from bfwrite to prevent grabbing nested mutexes. |
|
- Bitforce style changes. |
|
- Minor style changes. |
|
- Remove needless roundl define. |
|
- Made JSON error message verbose. |
|
- Fine-tune timing adjustment. Also remove old work_restart timing. |
|
- Check for gpu return times of >= 0, not just 0, to fix intensity dropping to |
|
-10. |
|
- Restart is zeroed in the mining thread so no need to do it inside the bitforce |
|
code. |
|
- More improvements to comms. BFL return nothing when throttling, so should not |
|
be considered an error. Instead repeat with a longer delay. |
|
- Polling every 10ms there's not much point checking the pthread_cond_timedwait |
|
as it just adds overhead. Simply check the value of work_restart in the bfl main |
|
polling loop. |
|
- Use a pthread conditional that is broadcast whenever work restarts are |
|
required. Create a generic wait function waiting a specified time on that |
|
conditional that returns if the condition is met or a specified time passed to |
|
it has elapsed. Use this to do smarter polling in bitforce to abort work, queue |
|
more work, and check for results to minimise time spent working needlessly. |
|
- Add busy time to wait time. |
|
- api.c put version up to 1.14 |
|
- Add tiny delay after writing to BFL Change BFL errors to something more human |
|
readable Send work busy re-tries after 10ms delay |
|
|
|
|
|
Version 2.4.4 - July 1, 2012 |
|
|
|
- Fix builds on non gnu platforms. |
|
- api.c ensure old mode is always available when not using --api-groups + quit() |
|
on param errors |
|
- Implement rudimentary X-Mining-Hashrate support. |
|
- Detect large swings in temperature when below the target temperature range and |
|
change fan by amounts dependant on the value of tdiff. |
|
- Adjust the fanspeed by the magnitude of the temperature difference when in the |
|
optimal range. |
|
- Revert "Restarting cgminer from within after ADL has been corrupted only leads |
|
to a crash. Display a warning only and disable fanspeed monitoring." |
|
- api.c fix json already closed |
|
- implement and document API option --api-groups |
|
- Put upper bounds to under 2 hours that work can be rolled into the future for |
|
bitcoind will deem it invalid beyond that. |
|
- define API option --api-groups |
|
- api.c allow unwell devices to be enabled so they can be cured |
|
- miner.php - fix/enable autorefresh for custom pages |
|
- miner.php allow custom summary pages - new 'Mobile' summary |
|
- Work around pools that advertise very low expire= time inappropriately as this |
|
leads to many false positives for stale shares detected. |
|
- Only show ztex board count if any exist. |
|
- There is no need for work to be a union in struct workio_cmd |
|
- fpgautils.c include a debug message for all unknown open errors |
|
- Don't keep rolling work right up to the expire= cut off. Use 2/3 of the time |
|
between the scantime and the expiry as cutoff for reusing work. |
|
- Log a specific error when serial opens fail due to lack of user permissions |
|
- Increase GPU timing resolution to microsecond and add sanity check to ensure |
|
times are positive. |
|
- Opencl code may start executing before the clfinish order is given to it so |
|
get the start timing used for dynamic intensity from before the kernel is |
|
queued. |
|
- fpgautils.c - set BAUD rate according to termio spec |
|
- fpgautils.c - linux ordering back to the correct way |
|
- miner.php remove unneeded '.'s |
|
- miner.php add auto refresh options |
|
- miner.php add 'restart' next to 'quit' |
|
- miner.php make fontname/size configurable with myminer.php |
|
- Make the pools array a dynamically allocated array to allow unlimited pools to |
|
be added. |
|
- Make the devices array a dynamically allocated array of pointers to allow |
|
unlimited devices. |
|
- Dynamic intensity for GPUs should be calculated on a per device basis. Clean |
|
up the code to only calculate it if required as well. |
|
- Use a queueing bool set under control_lock to prevent multiple calls to |
|
queue_request racing. |
|
- Use the work clone flag to determine if we should subtract it from the total |
|
queued variable and provide a subtract queued function to prevent looping over |
|
locked code. |
|
- Don't decrement staged extras count from longpoll work. |
|
- Count longpoll's contribution to the queue. |
|
- Increase queued count before pushing message. |
|
- Test we have enough work queued for pools with and without rolltime |
|
capability. |
|
- As work is sorted by age, we can discard the oldest work at regular intervals |
|
to keep only 1 of the newest work items per mining thread. |
|
- Roll work again after duplicating it to prevent duplicates on return to the |
|
clone function. |
|
- Abstract out work cloning and clone $mining_threads copies whenever a rollable |
|
work item is found and return a clone instead. |
|
- api.c display Pool Av in json |
|
- Take into account average getwork delay as a marker of pool communications |
|
when considering work stale. |
|
- Work out a rolling average getwork delay stored in pool_stats. |
|
- Getwork delay in stats should include retries for each getwork call. |
|
- Walk through the thread list instead of searching for them when disabling |
|
threads for dynamic mode. |
|
- Extend nrolltime to support the expiry= parameter. Do this by turning the |
|
rolltime bool into an integer set to the expiry time. If the pool supports |
|
rolltime but not expiry= then set the expiry time to the standard scantime. |
|
- When disabling fanspeed monitoring on adl failure, remove any twin GPU |
|
association. This could have been leading to hangs on machines with dual GPU |
|
cards when ADL failed. |
|
- modminer: Don't delay 2nd+ FPGAs during work restart |
|
- Disable OpenCL code when not available. |
|
- Fix openwrt crashing on regeneratehash() by making check_solve a noop. |
|
- FPGA - allow device detect override without an open failure |
|
- Fix sign warning. |
|
|
|
|
|
Version 2.4.3 - June 14, 2012 |
|
|
|
- can_roll and should_roll should have no bearing on the cycle period within the |
|
miner_thread so remove it. |
|
- Check for strategy being changed to load balance when enabling LPs. |
|
- Check that all threads on the device that called get_work are waiting on |
|
getwork before considering the pool lagging. |
|
- Iterate over each thread belonging to each device in the hashmeter instead of |
|
searching for them now that they're a list. |
|
- When using rotate pool strategy, ensure we only select from alive enabled |
|
pools. |
|
- Start longpoll from every pool when load balance strategy is in use. |
|
- Add mandatory and block fields to the work struct. Flag any shares that are |
|
detected as blocks as mandatory to submit, along with longpoll work from a |
|
previously rejecting pool. |
|
- Consider the fan optimal if fanspeed is dropping but within the optimal speed |
|
window. |
|
- Fix typo in some API messages (succeess/success) |
|
- api.c MMQ stat bugs |
|
- Bugfix: Fix warnings when built without libudev support |
|
- Bugfix: slay a variety of warnings |
|
- Bugfix: modminer: Fix unsigned/signed comparison and similar warnings |
|
- API add ModMinerQuad support |
|
- Bugfix: Honour forceauto parameter in serial_detect functions |
|
- modminer: Temperature sensor improvements |
|
- modminer: Make log messages more consistent in format |
|
- Only adjust GPU speed up if the fanspeed is within the normal fanrange and |
|
hasn't been turned to maximum speed under overheat conditions. |
|
- ModMiner use valid .name |
|
- New driver: BTCFPGA ModMiner |
|
- Abstract generally useful FPGA code into fpgautils.c |
|
- API add stats for pool getworks |
|
- miner.php option to hide specific fields from the display |
|
- miner.php add version numbers to the summary page |
|
- Update debian configs to v2.4.2 |
|
- Add API and FPGA READMEs into Makefile to be included in source distribution. |
|
- Icarus - fix unit64_t printf warnings |
|
|
|
|
|
Version 2.4.2 - June 2, 2012 |
|
|
|
- API.class compiled with Java SE 6.0_03 - works with Win7x64 |
|
- miner.php highlight devs too slow finding shares (possibly failing) |
|
- API update version to V1.11 and document changes |
|
- API save default config file if none specified |
|
- api.c save success incorrectly returns error |
|
- api.c replace BUFSIZ (linux/windows have different values) |
|
- Move RPC API content out of README to API-README |
|
- Open a longpoll connection if a pool is in the REJECTING state as it's the |
|
only way to re-enable it automatically. |
|
- Use only one longpoll as much as possible by using a pthread conditional |
|
broadcast that each longpoll thread waits on and checks if it's the current pool |
|
before |
|
- If shares are known stale, don't use them to decide to disable a pool for |
|
sequential rejects. |
|
- Restarting cgminer from within after ADL has been corrupted only leads to a |
|
crash. Display a warning only and disable fanspeed monitoring. |
|
- Icarus: fix abort calculation/allow user specified abort |
|
- Icarus: make --icarus-timing hidden and document it in FPGA-README |
|
- Icarus: high accuracy timing and other bitstream speed support |
|
- add-MIPSEB-to-icarus-for-BIG_ENDIAN |
|
- work_decode only needs swab32 on midstate under BIG ENDIAN |
|
- add compile command to api-example.c |
|
- save config bugfix: writing an extra ',' when no gpus |
|
- Add dpkg-source commits |
|
|
|
|
|
Version 2.4.1 - May 6, 2012 |
|
|
|
- In the unlikely event of finding a block, display the block solved count with |
|
the pool it came from for auditing. |
|
- Display the device summary on exit even if a device has been disabled. |
|
- Use correct pool enabled enums in api.c. |
|
- Import Debian packaging configs |
|
- Ensure we test for a pool recovering from idle so long as it's not set to |
|
disabled. |
|
- Fix pool number display. |
|
- Give cgminer -T message only if curses is in use. |
|
- Reinit_adl is no longer used. |
|
- API 'stats' allow devices to add their own stats also for testing/debug |
|
- API add getwork stats to cgminer - accesable from API 'stats' |
|
- Don't initialise variables to zero when in global scope since they're already |
|
initialised. |
|
- Get rid of unitialised variable warning when it's false. |
|
- Move a pool to POOL_REJECTING to be disabled only after 3 minutes of |
|
continuous rejected shares. |
|
- Some tweaks to reporting and logging. |
|
- Change FPGA detection order since BFL hangs on an ICA |
|
- API support new pool status |
|
- Add a temporarily disabled state for enabled pools called POOL_REJECTING and |
|
use the work from each longpoll to help determine when a rejecting pool has |
|
started working again. Switch pools based on the multipool strategy once a pool |
|
is re-enabled. |
|
- Removing extra debug |
|
- Fix the benchmark feature by bypassing the new networking code. |
|
- Reset sequential reject counter after a pool is disabled for when it is |
|
re-enabled. |
|
- Icarus - correct MH/s and U: with work restart set at 8 seconds |
|
- ztex updateFreq was always reporting on fpga 0 |
|
- Trying harder to get 1.15y working |
|
- Specifying threads on multi fpga boards extra cgpu |
|
- Missing the add cgpu per extra fpga on 1.15y boards |
|
- API add last share time to each pool |
|
- Don't try to reap curls if benchmarking is enabled. |
|
|
|
|
|
Version 2.4.0 - May 3, 2012 |
|
|
|
- Only show longpoll warning once when it has failed. |
|
- Convert hashes to an unsigned long long as well. |
|
- Detect pools that have issues represented by endless rejected shares and |
|
disable them, with a parameter to optionally disable this feature. |
|
- Bugfix: Use a 64-bit type for hashes_done (miner_thread) since it can overflow |
|
32-bit on some FPGAs |
|
- Implement an older header fix for a label existing before the pthread_cleanup |
|
macro. |
|
- Limit the number of curls we recruit on communication failures and with |
|
delaynet enabled to 5 by maintaining a per-pool curl count, and using a pthread |
|
conditional that wakes up when one is returned to the ring buffer. |
|
- Generalise add_pool() functions since they're repeated in add_pool_details. |
|
- Bugfix: Return failure, rather than quit, if BFwrite fails |
|
- Disable failing devices such that the user can attempt to re-enable them |
|
- Bugfix: thread_shutdown shouldn't try to free the device, since it's needed |
|
afterward |
|
- API bool's and 1TBS fixes |
|
- Icarus - minimise code delays and name timer variables |
|
- api.c V1.9 add 'restart' + redesign 'quit' so thread exits cleanly |
|
- api.c bug - remove extra ']'s in notify command |
|
- Increase pool watch interval to 30 seconds. |
|
- Reap curls that are unused for over a minute. This allows connections to be |
|
closed, thereby allowing the number of curl handles to always be the minimum |
|
necessary to not delay networking. |
|
- Use the ringbuffer of curls from the same pool for submit as well as getwork |
|
threads. Since the curl handles were already connected to the same pool and are |
|
immediately available, share submission will not be delayed by getworks. |
|
- Implement a scaleable networking framework designed to cope with any sized |
|
network requirements, yet minimise the number of connections being reopened. Do |
|
this by create a ring buffer linked list of curl handles to be used by getwork, |
|
recruiting extra handles when none is immediately available. |
|
- There is no need for the submit and getwork curls to be tied to the pool |
|
struct. |
|
- Do not recruit extra connection threads if there have been connection errors |
|
to the pool in question. |
|
- We should not retry submitting shares indefinitely or we may end up with a |
|
huge backlog during network outages, so discard stale shares if we failed to |
|
submit them and they've become stale in the interim. |
|
|
|
|
|
Version 2.3.6 - April 29, 2012 |
|
|
|
- Shorten stale share messages slightly. |
|
- Protect the freeing of current_hash under mutex_lock to prevent racing on it |
|
when set_curblock is hit concurrently. |
|
- Change default behaviour to submitting stale, removing the --submit-stale |
|
option and adding a --no-submit-stale option. |
|
- Make sure to start the getwork and submit threads when a pool is added on the |
|
fly. This fixes a crash when a pool is added to running cgminer and then |
|
switched to. |
|
- Faster hardware can easily outstrip the speed we can get work and submit |
|
shares when using only one connection per pool. |
|
- Test the queued list to see if any get/submits are already queued and if they |
|
are, start recruiting extra connections by generating new threads. |
|
- This allows us to reuse network connections at low loads but recuit new open |
|
connections as they're needed, so that cgminer can scale to hardware of any |
|
size. |
|
|
|
|
|
Version 2.3.5 - April 28, 2012 |
|
|
|
- Restarting cgminer leads to a socket that can't be bound for 60 seconds, so |
|
increase the interval that API binding waits to 30 seconds to minimise the |
|
number of times it will retry, spamming the logs. |
|
- Give a longpoll message for any longpoll that detects a block change, primary |
|
or backup, and also display which pool it was. |
|
- Decrease utility display to one decimal place. |
|
- Small cosmetic output alignment. |
|
- Add pool number to stale share message. |
|
- Add space to log output now that there is more screen real estate available. |
|
- Indentation clean up. |
|
- Merge branch 'master' of github.com:ckolivas/cgminer |
|
- Remove thread id display from rejected shares as well. |
|
- Merge pull request #185 from Diapolo/diakgcn |
|
- add goffset support for diakgcn with -v 1 and update kernel version |
|
- Set have_longpoll to true when there is at least one pool with longpoll. |
|
- Don't display the thread ID since it adds no useful information over the |
|
device number. |
|
- Don't display the first 8 bytes of a share since they will always be zero at |
|
>= 1 difficulty. |
|
- work->longpoll is reset across test_work_current so we need to recheck what |
|
pool it belongs to. |
|
- Use longpolls from backup pools with failover-only enabled just to check for |
|
block changes, but don't use them as work. |
|
- Start longpoll only after we have tried to extract the longpoll URL. |
|
- Check for submitold flag on resubmit of shares, and give different message for |
|
stale shares on retry. |
|
- Check for submitold before submitstale. |
|
- Don't force fresh curl connections on anything but longpoll threads. |
|
- Create one longpoll thread per pool, using backup pools for those pools that |
|
don't have longpoll. |
|
- Use the work created from the longpoll return only if we don't have |
|
failover-enabled, and only flag the work as a longpoll if it is the current |
|
pool. |
|
- This will work around the problem of trying to restart the single longpoll |
|
thread on pool changes that was leading to race conditions. |
|
- It will also have less work restarts from the multiple longpolls received from |
|
different pools. |
|
- Remove the ability to disable longpoll. It is not a useful feature and will |
|
conflict with planned changes to longpoll code. |
|
- Remove the invalid entries from the example configuration file. |
|
- Add support for latest ATI SDK on windows. |
|
- Export missing function from libztex. |
|
- miner.php change socktimeoutsec = 10 (it only waits once) |
|
- Bugfix: Make initial_args a const char** to satisfy exec argument type warning |
|
(on Windows only) |
|
- miner.php add a timeout so you don't sit and wait ... forever |
|
- Create discrete persistent submit and get work threads per pool, thus allowing |
|
all submitworks belonging to the same pool to reuse the same curl handle, and |
|
all getworks to reuse their own handle. |
|
- Use separate handles for submission to not make getwork potentially delay |
|
share submission which is time critical. |
|
- This will allow much more reusing of persistent connections instead of opening |
|
new ones which can flood routers. |
|
- This mandated a rework of the extra longpoll support (for when pools are |
|
switched) and this is managed by restarting longpoll cleanly and waiting for a |
|
thread join. |
|
- miner.php only show the current date header once |
|
- miner.php also add current time like single rig page |
|
- miner.php display rig 'when' table at top of the multi-rig summary page |
|
- README - add some Ztex details |
|
- api.c include zTex in the FPGA support list |
|
- api.c ensure 'devs' shows PGA's when only PGA code is compiled |
|
- cgminer.c sharelog code consistency and compile warning fix |
|
- README correct API version number |
|
- README spelling error |
|
- api.c combine all pairs of sprintfs() |
|
- api.c uncomment and use BLANK (and COMMA) |
|
- Code style cleanup |
|
- Annotating frequency changes with the changed from value |
|
- README clarification of 'notify' command |
|
- README update for API RPC 'devdetails' |
|
- api.c 'devdetails' list static details of devices |
|
- Using less heap space as my TP-Link seems to not handle this much |
|
|
|
|
|
Version 2.3.4 - April 25, 2012 |
|
|
|
- Extensively document the cause of GPU device issues and the use of --gpu-map. |
|
- Support for share logging |
|
- Detect poorly performing combination of SDK and phatk kernel and add verbose |
|
warning at startup. |
|
- Icarus update to new add_cgpu() |
|
- Icarus driver working with Linux and Windows |
|
- api.c fix unused variable compile warning |
|
- Display all OpenCL devices when -n is called as well to allow debugging of |
|
differential mapping of OpenCL to ADL. |
|
- Add a --gpu-map option which will allow arbitrarily mapping ADL devices to |
|
OpenCL devices for instances where association by enumeration alone fails. |
|
- Increase upper limit on number of extra items to queue as some FPGA code can't |
|
yet reliably keep many devices busy. |
|
- Display configuration file information when -c option is passed and only when |
|
file exists on loading default config file. |
|
- Display configuration file loaded, if any, and debug output if configuration |
|
file parsing failed. |
|
- Add missing ztex header to Makefile for distribution. |
|
- Document long-form COM port device names on Windows, required to specify |
|
serial ports above 9 |
|
- Include ztex bitstreams firmware in distribution and install if configured in. |
|
- Style police on driver-ztex.c |
|
- work_restart should only be changed by cgminer.c now |
|
- Shut down the api cleanly when the api thread is cancelled. This should allow |
|
the api socket to be closed successfully to next be reopened with app_restart. |
|
- Make a union for cgpu device handles, and rename "device" to "device_ztex" |
|
since it's Ztex-specific |
|
- Initialise name variable. |
|
- Remove unnecessary check for variable that always has memory allocated. |
|
- Bugfix: Missing "break" no-op in default case |
|
- Make the status window and log window as large as can fit on startup, |
|
rechecking to see if it can be enlarged after the fact. This allows any number |
|
of devices to be displayed provided the window is made long enough without |
|
corrupting the output. |
|
- Style police on libztex.c. |
|
- API add removepool like the screen interface |
|

|
username |
|
- Set lp_path to NULL after free for consistency. |
|
- Removing dmalloc import left behind by mistake |
|
- Fixing leak in resp_hdr_cb |
|
- miner.php warning highlight GPU stats if they are zero (e.g. ADL not enabled) |

|
|
Version 2.3.3 - April 15, 2012 |
|
|
|
- Don't even display that cpumining is disabled on ./configure to discourage |
|
people from enabling it. |
|
- Do a complete cgminer restart if the ATI Display Library fails, as it does on |
|
windows after running for some time, when fanspeed reporting fails. |
|
- Cache the initial arguments passed to cgminer and implement an attempted |
|
restart option from the settings menu. |
|
- Disable per-device status lines when there are more than 8 devices since |
|
screen output will be corrupted, enumerating them to the log output instead at |
|
startup. |
|
- Reuse Vals[] array more than W[] till they're re-initialised on the second |
|
sha256 cycle in poclbm kernel. |
|
- Minor variable alignment in poclbm kernel. |
|
- Make sure to disable devices with any status not being DEV_ENABLED to ensure |
|
that thermal cutoff code works as it was setting the status to DEV_RECOVER. |
|
- Re-initialising ADL simply made the driver fail since it is corruption over |
|
time within the windows driver that's responsible. Revert "Attempt to |
|
re-initialise ADL should a device that previously reported fanspeed stops |
|
reporting it." |
|
- Microoptimise poclbm kernel by ordering Val variables according to usage |
|
frequency. |
|
|
|
|
|
Version 2.3.2 - March 31, 2012 |
|
|
|
- Damping small changes in hashrate so dramatically has the tendency to always |
|
make the hashrate underread so go back to gentle damping instead. |
|
- Revert the crossover of variables from Vals to W in poclbm kernel now that |
|
Vals are the first declared variables so they're used more frequently. |
|
- Vals variables appearing first in the array in poclbm is faster. |
|
- Change the preferred vector width to 1 for Tahiti only, not all poclbm |
|
kernels. |
|
- Use a time constant 0.63 for when large changes in hashrate are detected to |
|
damp change in case the large change is an aliasing artefact instead of a real |
|
chang |
|
- Only increment stale counter if the detected stales are discarded. |
|
- Attempt to re-initialise ADL should a device that previously reported fanspeed |
|
stops reporting it. |
|
- Move the ADL setup and clearing to separate functions and provide a reinit_adl |
|
function to be used when adl fails while running. |
|
- Use slightly more damping on the decay time function in the never-ending quest |
|
to smooth off the hashmeter. |
|
- Set the starting fanspeed to a safe and fairly neutral 50% when autofan is |
|
enabled. |
|
- Provide locking around updates of cgpu hashrates as well to prevent multiple |
|
threads accessing data fields on the same device. |
|
- Display the beginning of the new block in verbose mode in the logs. |
|
- Reinstate old diablo kernel variable ordering from 120222, adding only goffset |
|
and vector size hint. The massive variable ordering change only helped one SDK |
|
on |
|
- Change the version number on the correct kernels. |
|
- api.c devicecode/osinfo incorrectly swapped for json |
|
- Add extensive instructions on how to make a native windows build. |
|
- Update version numbers of poclbm and diablo kernels as their APIs have also |
|
changed. |
|
- Use global offset parameter to diablo and poclbm kernel ONLY for 1 vector |
|
kernels. |
|
- Use poclbm preferentially on Tahiti now regardless of SDK. |
|
- Remove unused constant passed to poclbm. |
|
- Clean up use of macros in poclbm and use bitselect everywhere possible. |
|
- Add vector type hint to diablo kernel. |
|
- Add worksize and vector attribute hints to the poclbm kernel. |
|
- Spaces for non-aligned variables in poclbm. |
|
- More tidying of poclbm. |
|
- Swap Vals and W variables where they can overlap in poclbm. |
|
- More tidying of poclbm. |
|
- Tidy up first half of poclbm. |
|
- Clean up use of any() by diablo and poclbm kernels. |
|
- Minor variable symmetry changes in poclbm. |
|
- Put additions on separate lines for consistency in poclbm. |
|
- Consolidate last use of W11 into Vals4 in poclbm. |
|
- Change email due to SPAM |
|
- api.c miner.php add a '*' to the front of all notify counters - simplifies |
|
future support of new counters |
|
- miner.php add display 'notify' command |
|
- Small change to help arch's without processor affinity |
|
- Fix bitforce compile error |
|
- api.c notify should report disabled devices also - of course |
|
- API returns the simple device history with the 'notify' command |
|
- code changes for supporting a simple device history |
|
- api.c Report an OS string in config to help with device issues |
|
- api.c fix Log Interval - integer in JSON |
|
- api.c config 'Device Code' to show list of compiled devices + README |
|
- api.c increase buffer size close to current code allowable limit |
|
- removed 8-component vector support from kernel, as this is not supported in |
|
CGMINER anyway |
|
- forgot to update kernel modification date, fixed ;) |
|
- reordered an addition in the kernel, which results in less instructions used |
|
in the GPU ISA code for GCN |
|
- miner.php: option for readonly or check privileged access |
|
- Ignore reduntant-with-build options --disable-gpu, --no-adl, and --no-restart |
|
- miner.php: ereg_replace is DEPRECATED so use preg_replace instead |
|
- Make curses TUI support optional at compile-time. |
|
- Bugfix: AC_ARG_WITH provides withval instead of enableval |
|
- miner.php split devs output for different devices |
|
- api.c: correct error messages |
|
- icarus.c modify (regular) timeout warning to only be debug |
|
- icarus.c set the windows TODO timeout |
|
- Allow specifying a specific driver for --scan-serial |
|
- optimized nonce-check and output code for -v 2 and -v 4 |
|
- Bugfix: Check for libudev header (not just library) in configure, and document |
|
optional dependency |
|
- Add API support for Icarus and Bitforce |
|
- Next API version is 1.4 (1.3 is current) |
|
- README/api.c add "When" the request was processed to STATUS |
|
- Bugfix: ZLX to read BitFORCE temp, not ZKX -.- |
|
- Use libudev to autodetect BitFORCE GPUs, if available |
|
- Use the return value of fan_autotune to set fan_optimal instead of passing it |
|
as a pointer. |
|
- Pass the lasttemp from the device we're using to adjust fanspeed in twin |
|
devices. |
|
- fix the name to 3 chars, fix the multi-icarus support |
|
- Bugfix: "-S auto" is the default if no -S is specified, and there is no such |
|
delay in using it |
|
- README add information missing from --scan-serial |
|
- Update README RPC API Version comment |
|
- Bugfix: Allow enabling CPU even without OpenCL support |
|
- Change failed-to-mine number of requested shares messge to avoid segfault on |
|
recursive calling of quit(). |
|
- Get rid of extra char which is just truncated in poclbm kernel. |
|
- only small code formating changes |
|
- removed vec_step() as this could lead to errors on older SDKs |
|
- unified code for generating nonce in kernel and moved addition of base to the |
|
end -> faster |
|
|
|
Version 2.3.1 - February 24, 2012 |
|
|
|
- Revert input and output code on diakgcn and phatk kernels to old style which |
|
worked better for older hardware and SDKs. |
|
- Add a vector*worksize parameter passed to those kernels to avoid one op. |
|
- Increase the speed of hashrate adaptation. |
|
- Only send out extra longpoll requests if we want longpolls. |
|
- API implement addpool command |
|
- API return the untouched Total MH also (API now version 1.3) |
|
- Add enable/disablepool to miner.php example and reduce font size 1pt |
|
|
|
|
|
Version 2.3.0 - February 23, 2012 |
|
|
|
- Consider extra longpoll work items as staged_extra so as to make sure we queue |
|
more work if queueing regular work items as longpolls. |
|
- Use diablo kernel on all future SDKs for Tahiti and set preferred vector width |
|
to 1 on poclbm kernel only. |
|
- Explicitly type the constants in diakgcn kernel as uint, to be in line with |
|
poclbm kernel. |
|
- Reset all hash counters at the same time as resetting start times to get |
|
accurate hashrates on exiting which is mandatory for benchmarking. |
|
- Report thread out before it starts to avoid being flagged as sick when waiting |
|
for the first work item. |
|
- Don't disable and re-enable devices as they may recover and in the meantime |
|
have their status set to OFF. |
|
- API new commands enablepool and disablepool (version already incremented) |
|
- Tolerate new-format temperature readings for bitforce |
|
- Modify cgminer.c pool control to allow API to call it |
|
- Bugfix: Fix BitFORCE driver memory leak in debug logging |
|
- Extra byte was being unused in poclbm leading to failure on some platforms. |
|
- Explicitly type the constants in poclbm kernel as uint. |
|
- Don't save 'include' when saving the configuration |
|
- Allow configuration file to include another recursively |
|
- Use the SDK and hardware information to choose good performing default |
|
kernels. |
|
- Move phatk kernel to offset vector based nonce bases as well. |
|
- Add a --benchmark feature which works on a fake item indefinitely to compare |
|
device performance without any server or networking influence. |
|
- Allow writing of multiple worksizes to the configuration file. |
|
- Allow writing of multiple vector sizes to the configuration file. |
|
- Allow writing of multiple kernels to the configuration file. |
|
- Allow multiple different kernels to be chosen per device. |
|
- Allow the worksize to be set per-device. |
|
- Allow different vectors to be set per device. |
|
- If we're well below the target temperature, increase gpu engine speed back to |
|
maximum in case we have gotten lost between profiles during an idle period. |
|
- We should be setting the value of fan_optimal, not its address. |
|
- As all kernels will be new versions it's an opportunity to change the .bin |
|
format and make it simpler. Specifying bitalign is redundant and long can be l. |
|
- Use any() in kernel output code. |
|
- Put the nonce for each vector offset in advance, avoiding one extra addition |
|
in the kernel. |
|
- Reset times after all mining threads are started to make estimating hashrates |
|
easier at startup. |
|
- Bugfix: allow no-exec (NX) stack |
|
- Fix minor warning. |
|
- fix the bitforce.c code style follow 1TBS |
|
- fix icarus.c compile warning |
|
- small changes to speedup no vec for AMD 898.1 OCL runtime |
|
- Update licensing to GPL V3. |
|
- Reset the longpoll flag after it's been used once to prevent it restarting |
|
work again. |
|
- Begin import of DiabloMiner kernel. |
|
- Modify API debug messages to say API instead of DBG |
|
- When API shuts down cgminer don't kill itself |
|
- Don't make rolled work from the longpoll be seen as other longpoll work items. |
|
- API add 'privileged' command so can verify access level |
|
- Set the lp_sent variable under lock since there will almost always be a race |
|
on setting this variable, potentially leading to multiple LPs being sent out. |
|
- API restrict access to all non display commands by default |
|
- Update API version to 1.2 for new 'Log Interval' |
|
- API add --log Interval to 'config' reply |
|
- --api-allow special case 0/0 means all |
|
|
|
|
|
Version 2.2.7 - February 20, 2012 |
|
|
|
- Send out extra longpolls when we have switched pools and the longpoll thread |
|
is still bound to the old one. This is particularly useful with p2pool where |
|
longpolls do not correlate with main bitcoin block change and would have led to |
|
high reject rates on failover. |
|
- Store whether a work item is the result of a longpoll or not in struct work |
|
and use it to help determine block changes directly from the work longpoll bool. |
|
- Keep track of when a longpoll has been sent for a pool and if the current pool |
|
is requesting work but has not sent a longpoll request, convert one of the work |
|
items to a longpoll. |
|
- Store the longpoll url in the pool struct and update it from the pool_active |
|
test in case it changes. This is to allow further changes to longpoll management |
|
on switching pools. |
|
- Re-check for a longpoll supporting pool every 30 seconds if none is found |
|
initially. |
|
- Report threads as busy waiting on getwork on startup to avoid them being |
|
flagged sick on startup during slow networking. |
|
- Allow devices that are disabled due to overheating to be flagged as recovering |
|
instead of disabling them and re-enable them if they're below ideal temperatures |
|
- Tahiti prefers worksize 64 with poclbm. |
|
- No need to expressly retain the opencl program now that the zero binary issue |
|
is fixed. This actually fixes cgminer to work with the latest SDK included with |
|
the ATI catalyst driver 12.2. |
|
- Show error code on any opencl failure status. |
|
- Add detection for version 898.1 SDK as well but only give SDK 2.6 warning once |
|
on startup instead of with each device initialisation. |
|
- Always use a fresh connection for longpoll as prolonged persistent connections |
|
can fail for many reasons. |
|
- Keep track of intended engine clock speed and only adjust up if it's higher |
|
than the last intended speed. This avoids setting the clock speed to one |
|
relative to a lower profile one by mistake. |
|
- Use gpu-memdiff on startup if an engine clockspeed is set and a memdiff value |
|
is set. |
|
- Revert "Adjust engine speed up according to performance level engine setting, |
|
not the current engine speed." - ineffectual. |
|
- Freeze the queues on all threads that are sent the pause message to prevent |
|
them trying to start up again with saved pings in their queues. |
|
- Updates to diakgcn kernel/ |
|
- Consolidate all screen updates to the watchdog thread and touch both windows |
|
before refresh. |
|
- Curses will be disabled in clean_up so don't do it early in kill_work, and |
|
disable_adl so that GPU settings may be restored to normal in case shutting down |
|
curses leads to instability on windows. |
|
- Stop the mining threads before trying to kill them. |
|
- Plain refresh() does not give reliably screen updates so get rid of all uses |
|
of it. |
|
- First release with working diakgcn kernel. |
|
|
|
Version 2.2.6 - February 16, 2012 |
|
|
|
- Provide warning on each startup about sdk 2.6 |
|
- Fix unused warnings on win32. |
|
- bitforce: Simplify BFopen WIN32 ifdef/else |
|
- Fix initialization warning with jansson 1.3 |
|
- bitforce: Cleanup extraneous TODO that isn't needed |
|
- Move tcsetattr (and new tcflush) into *nix BFopen to simplify things a bit |
|
- Add message explaining 2nd thread disabling for dynamic mode and how to tune |
|
it. |
|
- Move logwindow down once number of devices is known. |
|
- Automatically choose phatk kernel for bitalign non-gcn ATI cards, and then |
|
only select poclbm if SDK2.6 is detected. |
|
- Allow the refresh interval to be adjusted in dynamic intensity with a |
|
--gpu-dyninterval parameter. |
|
- Make curses display visible right from the beginning and fix the window sizes |
|
so the initial messages don't get lost once the status window is drawn. |
|
- The amount of work scanned can fluctuate when intensity changes and since we |
|
do this one cycle behind, we increment the work more than enough to prevent |
|
repeati |
|
- bitforce: Set a 30 second timeout for serial port on Windows, since the |
|
default is undefined |
|
- Use PreVal4addT1 instead of PreVal4 in poclbm kernel. |
|
- Import PreVal4 and PreVal0 into poclbm kernel. |
|
- Import more prepared constants into poclbm kernel. |
|
- Keep variables in one array but use Vals[] name for consistency with other |
|
kernel designs. |
|
- Replace constants that are mandatorily added in poclbm kernel with one value. |
|
- Remove addition of final constant before testing for result in poclbm kernel. |
|
- Hand optimise variable addition order. |
|
- Hand optimise first variable declaration order in poclbm kernel. |
|
- Radical reordering machine based first pass to change variables as late as |
|
possible, bringing their usage close together. |
|
- fix strcpy NULL pointer if env HOME unset. |
|
- bitforce: Disable automatic scanning when at least one device is specified |
|
manually |
|
- Unroll all poclbm additions to enable further optimisations. |
|
|
|
|
|
Version 2.2.5 - February 13, 2012 |
|
|
|
- Make output buffer write only as per Diapolo's suggestion. |
|
- Constify nonce in poclbm. |
|
- Use local and group id on poclbm kernel as well. |
|
- Microoptimise phatk kernel on return code. |
|
- Adjust engine speed up according to performance level engine setting, not the |
|
current engine speed. |
|
- Try to load a binary if we've defaulted to the poclbm kernel on SDK2.6 |
|
- Use the poclbm kernel on SDK2.6 with bitalign devices only if there is no |
|
binary available. |
|
- Further generic microoptimisations to poclbm kernel. |
|
- The longstanding generation of a zero sized binary appears to be due to the |
|
OpenCL library putting the binary in a RANDOM SLOT amongst 4 possible binary |
|
locations. Iterate over each of them after building from source till the real |
|
binary is found and use that. |
|
- Fix harmless warnings with -Wsign-compare to allow cgminer to build with -W. |
|
- Fix missing field initialisers warnings. |
|
- Put win32 equivalents of nanosleep and sleep into compat.h fixing sleep() for |
|
adl.c. |
|
- Restore compatibility with Jansson 1.3 and 2.0 (api.c required 2.1) |
|
- Modularized logging, support for priority based logging |
|
- Move CPU chipset specific optimization into device-cpu |
|
|
|
|
|
Version 2.2.4 - February 11, 2012 |
|
|
|
- Fix double definition of A0 B0 to zeroA zeroB. |
|
- Retain cl program after successfully loading a binary image. May decrease |
|
failures to build kernels at startup. |
|
- Variable unused after this so remove setting it. |
|
- BFI INT patching is not necessarily true on binary loading of files and not |
|
true on ATI SDK2.6+. Report bitalign instead. |
|
- Various string fixes for reject reason. |
|
- Generalize --temp-cutoff and implement support for reading temperature from |
|
BitFORCE FPGAs |
|
- Change message from recovered to alive since it is used on startup as well as |
|
when a pool has recovered. |
|
- Start mining as soon as any pool is found active and rely on the watchpool |
|
thread to bring up other pools. |
|
- Delayed responses from testing pools that are down can hold up the watchdog |
|
thread from getting to its device testing code, leading to false detection of |
|
the GPU not checking in, and can substantially delay auto gpu/auto fan |
|
management leading to overheating. Move pool watching to its own thread. |
|
- Bugfix: BitFORCE index needs to be static to count correctly |
|
- Space out retrieval of extra work according to the number of mining threads. |
|
- Make shutdown more robust. Enable the input thread only after the other |
|
threads exist. Don't kill off the workio thread and use it to exit main() only |
|
if there is an unexpected problem. Use kill_work() for all anticipated shutdowns |
|
where possible. Remove unused thread entry. |
|
- Change poclbm version number. |
|
- One array is faster than 2 separate arrays so change to that in poclbm kernel. |
|
- Microoptimisations to poclbm kernel which increase throughput slightly. |
|
- Import diablominer kernel. Currently disabled as not working. |
|
- Import diapolo kernel. Currently disabled as not working. |
|
- Conflicting entries of cl_kernel may have been causing problems, and |
|
automatically chosen kernel type was not being passed on. Rename the enum to |
|
cl_kernels and store the chosen kernel in each clState. |
|
- Set cl_amd_media_ops with the BITALIGN flag and allow non-bitselect devices to |
|
build. |
|
- ALlow much longer filenames for kernels to load properly. |
|
- Allow different kernels to be used by different devices and fix the logic fail |
|
of overcorrecting on last commit with !strstr. |
|
- Fix kernel selection process and build error. |
|
- queue_phatk_kernel now uses CL_SET_VARG() for base-nonce(s), too |
|
- added OpenCL >= 1.1 detection code, in preparation of OpenCL 1.1 global offset |
|
parameter support |
|
- Use K array explicitly to make it clear what is being added. |
|
- Work items have a tendency to expire at exactly the same time and we don't |
|
queue extra items when there are plenty in the queue, regardless of age. Allow |
|
extra work items to be queued if adequate time has passed since we last |
|
requested work even if over the limit. |
|
- Discard work when failover-only is enabled and the work has come from a |
|
different pool. |
|
- Missing include to build on newer mingw32. |
|
- Move from the thread safe localtime_r to regular localtime which is the only |
|
one supported on newer pthread libraries on mingw32 to make it compile with the |
|
newer ming. Thread safety is of no importance where localtime is used in this |
|
code. |
|
- Define in_addr_t in windows if required |
|
- sys/wait.h not required in windows |
|
- Allow API to restrict access by IP address |
|
- Add pool switching to example miner.php |
|
- Display X-Reject-Reason, when provided |
|
- Remove the test for whether the device is on the highest profil level before |
|
raising the GPU speed as it is ineffectual and may prevent raising the GPU |
|
speed. |
|
- Remove unnecessary check for opt_debug one every invocation of applog at |
|
LOG_DEBUG level and place the check in applog(). |
|
|
|
|
|
Version 2.2.3 - February 6, 2012 |
|
|
|
- Revert "Rewrite the convoluted get_work() function to be much simpler and roll |
|
work as much as possible with each new work item." This seems to cause a race on |
|
work in free_work(). Presumably other threads are still accessing the structure. |
|
|
|
|
|
Version 2.2.2 - February 6, 2012 |
|
|
|
- Provide support for the submitold extension on a per-pool basis based on the |
|
value being detected in a longpoll. |
|
- Don't send a ping to a dynamic device if it's not enabled as that will just |
|
enable it for one pass and then disable it again. |
|
- Rewrite the convoluted get_work() function to be much simpler and roll work as |
|
much as possible with each new work item. |
|
- Roll as much work as possible from the work returned from a longpoll. |
|
- Rolling work on each loop through the mining thread serves no purpose. |
|
- Allow to stage more than necessary work items if we're just rolling work. |
|
- Replace divide_work with reuse_work function used twice. |
|
- Give rolled work a new ID to make sure there is no confusion in the hashtable |
|
lookups. |
|
- Remove now-defunct hash_div variables. |
|
- Remove unused get_dondata function. |
|
- Silence ADL warnings. |
|
- Silence unused parameter warnings. |
|
- Stagger the restart of every next thread per device to keep devices busy ahead |
|
of accessory threads per device. |
|
- Deprecate the --donation feature. Needlessly complex, questionable usefulness, |
|
depends on author's server and a central pool of some kind, and was not heavily |
|
adopted. |
|
- It's devices that report back now, not threads, update message. |
|
- Continue auto-management of fan and engine speeds even if a device is disabled |
|
for safety reasons. |
|
- No need to check we're highest performance level when throttling GPU engine |
|
speed. |
|
- Abstract out tests for whether work has come from a block that has been seen |
|
before and whether a string is from a previously seen block. |
|
- Probe but don't set the timeout to 15 seconds as some networks take a long |
|
time to timeout. |
|
- Remove most compiler warnings from api.c |
|
- Add last share's pool info in cgpu_info |
|
- Allow the OpenCL platform ID to be chosen with --gpu-platform. |
|
- Iterate over all platforms displaying their information and number of devices |
|
when --ndevs is called. |
|
- Deprecate main.c |
|
- Some networks can take a long time to resolve so go back to 60 second timeouts |
|
instead of 15. |
|
- Only enable curses on failure if curses is desired. |
|
- Fix warnings in bitforce.c |
|
- Bugfix: Need to open BitForce tty for read-write |
|
- Fix various build issues. |
|
- Modularize code: main.c -> device-cpu + device-gpu |
|
- Fix phatk kernel not working on non-bitalign capable devices (Nvidia, older |
|
ATI). |
|
- Update poclbm kernel for better performance on GCN and new SDKs with bitalign |
|
support when not BFI INT patching. Update phatk kernel to work properly for non |
|
BFI INT patched kernels, providing support for phatk to run on GCN and non-ATI |
|
cards. |
|
- Return last accepted share pool/time for devices |
|
- Display accepted share pool/time for CPUs |
|
- Bug intensity always shows GPU 0 |
|
- Update example web miner.php to use new API commands |
|
|
|
|
|
Version 2.2.1 - January 30, 2012 |
|
|
|
NOTE - The GPU Device reordering in 2.2.0 by default was considered a bad idea |
|
so the original GPU ordering is used by default again unless reordering is |
|
explicitly requested. |
|
|
|
- Fix bitforce failing to build into cgminer. |
|
- Add missing options to write config function. |
|
- Add a --gpu-reorder option to only reorder devices according to PCI Bus ID |
|
when requested. |
|
- Fix for midstate support being broken on pools that supported no-midstate |
|
work by ensuring numbers are 32 bits in sha2.c |
|
- Set virtual GPUs to work when ADL is disabled or all mining will occur on GPU |
|
0. |
|
- Add information about paused threads in the menu status. |
|
- Disable all but the first thread on GPUs in dynamic mode for better |
|
interactivity. |
|
- Set the latest network access time on share submission for --net-delay even if |
|
we're not delaying that submission for further network access. |
|
- Clear adl on exiting after probing values since it may attempt to overclock. |
|
- As share submission is usually staggered, and delays can be costly, submit |
|
shares without delay even when --net-delay is enabled. |
|
- Display GPU number and device name when ADL is successfully enabled on it. |
|
- Display GPU ordering remapping in verbose mode. |
|
- Don't fail in the case the number of ADL and OpenCL devices do not match, and |
|
do not attempt to reorder devices unless they match. Instead give a warning |
|
about |
|
- Display error codes should ADL not return ADL_OK in the more critical function |
|
calls. |
|
- Fix unused warning. |
|
- Fix compile warnings in api.c |
|
- Add extensive ADL based device info in debug mode. |
|
- Make --ndevs display verbose opencl information as well to make debugging |
|
version information easier. |
|
- Display information about the opencl platform with verbose enabled. |
|
- Explicitly check for nvidia in opencl platform strings as well. |
|
|
|
|
|
Version 2.2.0 - January 29, 2012 |
|
|
|
NOTE: GPU Device order will change with this release with ATI GPUs as cgminer |
|
now can enumerate them according to their Bus ID which means the values should |
|
now correlate with their physical position on the motherboard. |
|
|
|
- Default to poclbm kernel on Tahiti (7970) since phatk does not work, even |
|
though performance is sub-standard so that at least it will mine successfully by |
|
defau |
|
- Retain cl program after every possible place we might build the program. |
|
- Update ADL SDK URL. |
|
- Fix potential overflow. |
|
- Map GPU devices to virtual devices in their true physical order based on |
|
BusNumber. |
|
- Change the warning that comes with failure to init cl on a device to be more |
|
generic and accurate. |
|
- Advertise longpoll support in X-Mining-Extensions |
|
- Detect dual GPU cards by iterating through all GPUs, finding ones without |
|
fanspeed and matching twins with fanspeed one bus ID apart. |
|
- Do not attempt to build the program that becomes the kernel twice. This could |
|
have been leading to failures on initialising cl. |
|
- Some opencl compilers have issues with no spaces after -D in the compiler |
|
options. |
|
- Allow intensity up to 14. |
|
- Use calloced stack memory for CompilerOptions to ensure sprintf writes to the |
|
beginning of the char. |
|
- Whitelist 79x0 cards to prefer no vectors as they perform better without. |
|
- Adjust fan speed gently while in the optimal range when temperature is |
|
drifting to minimise overshoot in either direction. |
|
- Detect dual GPU cards via the indirect information of - 1st card has a fan |
|
controller. 2nd card does not have a fan controller, cards share the same device |
|
name |
|
- Instead of using the BFI_INT patching hack on any device reporting |
|
cl_amd_media_ops, create a whitelist of devices that need it. This should enable |
|
GCN architec |
|
- Fixed API compiling issue on OS X |
|
- Add more explanation of JSON format and the 'save' command |
|
- Return an error if using ADL API commands when it's not available |
|
- Read off lpThermalControllerInfo from each ADL device. |
|
- Add ADL_Overdrive5_ThermalDevices_Enum interface. |
|
- Add API commands: config, switchpool, gpu settings, save |
|
- Implement socks4 proxy support. |
|
- Fix send() for JSON strings |
|
- Introduce a --net-delay option which guarantees at least 250ms between any |
|
networking requests to not overload slow routers. |
|
- Generalise locking init code. |
|
- Allow invalid values to be in the configuration file, just skipping over them |
|
provided the rest of the file is valid JSON. This will allow older configurat |
|
- Allow CPU mining explicitly enable only if other mining support is built in. |
|
- BitForce FPGA support |
|
- Configure out building and support of all CPU mining code unless |
|
--enable-cpumining is enabled. |
|
- Allow parsed values to be zero which will allow 0 values in the config file to |
|
work. |
|
- Advertise that we can make our own midstate, so the pool can skip generating |
|
it for us |
|
- Refactor the CPU scanhash_* functions to use a common API. Fixes bugs. |
|
- Don't consider a pool lagging if a request has only just been filed. This |
|
should decrease the false positives for "pool not providing work fast enough". |
|
- Invalidating work after longpoll made hash_pop return no work giving a false |
|
positive for dead pool. Rework hash_pop to retry while finds no staged work u |
|
- Remove TCP_NODELAY from curl options as many small packets may be contributing |
|
to network overload, when --net-delay is enabled. |
|
- Refactor miner_thread to be common code for any kind of device |
|
- Simplify submit_nonce loop and avoid potentially missing FOUND - 1 entry. |
|

|
- Refactor to abstract device-specific code |
|

|
|
|
Version 2.1.2 - January 6, 2012 |
|
|
|
- If api-description is specified, save it when writing the config file |
|
- Adjust utility width to be constant maximum as well. |
|
- Add percent signs to reject ratio outputs |
|
- Should the donation pool fail, don't make the fallover pool behave as though |
|
the primary pool is lagging. |
|
- Use an alternative pool should the donation getwork fail. |
|
|
|
|
|
Version 2.1.1 - January 1, 2012 |
|
|
|
- Include API examples in distribution tarball. |
|
- Don't attempt to pthread_join when cancelling threads as they're already |
|
detached and doing so can lead to a segfault. |
|
- Give more generic message if slow pool at startup is the donation pool. |
|
- Continue to attempt restarting GPU threads if they're flagged dead at 1 min. |
|
intervals. |
|
- Don't attempt to restart sick flagged GPUs while they're still registering |
|
activity. |
|
- Make curl use fresh connections whenever there is any communication issue |
|
in case there are dead persistent connections preventing further comms from |
|
working. |
|
- Display pool in summary if only 1 pool. |
|
- Adjust column width of A/R/HW to be the maximum of any device and align them. |
|
|
|
|
|
Version 2.1.0 - December 27, 2011 |
|
|
|
- Major infrastructure upgrade with RPC interface for controlling via sockets |
|
encoded with/without JSON courtesy of Andrew Smith. Added documentation for |
|
use of the API and sample code to use with it. |
|
- Updated linux-usb-cgminer document. |
|
- Rewrite of longpoll mechanism to choose the current pool wherever possible to |
|
use for the longpoll, or any pool that supports longpoll if the current one |
|
does not. |
|
- Display information about longpoll when the chosen server has changed. |
|
- Fix the bug where longpoll generated work may have been sent back to the |
|
wrong pool, causing rejects. |
|
- Fix a few race conditions on closing cgminer which caused some of the crashes |
|
on exit. |
|
- Only adjust gpu engine speed in autotune mode if the gpu is currently at the |
|
performance level of that being adjusted. |
|
- Various fixes for parsing/writing of configuration files. |
|
- Do not add blank lines for threads of unused CPUs. |
|
- Show which pool is unresponsive on startup. |
|
- Only show GPU management menu item if GPUs are in use. |
|
- Align most device columns in the curses display. |
|
|
|
|
|
Version 2.0.8 - November 11, 2011 |
|
|
|
- Make longpoll do a mandatory flushing of all work even if the block hasn't |
|
changed, thus supporting longpoll initiated work change of any sort and merged |
|
mining. |
|
- Byteswap computed hash in hashtest so it can be correctly checked. This fixes |
|
the very rare possibility that a block solve on solo mining was missed. |
|
- Add x86_64 w64 mingw32 target |
|
- Allow a fixed speed difference between memory and GPU clock speed with |
|
--gpu-memdiff that will change memory speed when GPU speed is changed in |
|
autotune mode. |
|
- Don't load the default config if a config file is specified on the command |
|
line. |
|
- Don't build VIA on apple since -a auto bombs instead of gracefully ignoring |
|
VIA failing. |
|
- Build fix for dlopen/dlclose errors in glibc. |
|
|
|
|
|
Version 2.0.7 - October 17, 2011 |
|
|
|
- Support work without midstate or hash1, which are deprecated in bitcoind 0.5+ |
|
- Go to kernel build should we fail to clCreateProgramWithBinary instead of |
|
failing on that device. This should fix the windows problems with devices not |
|
initialising. |
|
- Support new configuration file format courtesy of Chris Savery which can write |
|
the config file from the menu and will load it on startup. |
|
- Write unix configuration to .cgminer/cgminer.conf by default and prompt to |
|
overwrite if given a filename from the menu that exists. |
|
|
|
|
|
Version 2.0.6 - October 9, 2011 |
|
|
|
- Must initialise the donorpool mutex or it fails on windows. |
|
- Don't make donation work interfere with block change detection allowing |
|
donation to work regardless of the block chain we're mining on. |
|
- Expire shares as stale with a separate timeout from the scantime, defaulting |
|
to 120 seconds. |
|
- Retry pools after a delay of 15 seconds if none can be contacted on startup |
|
unless a key is pressed. |
|
- Don't try to build adl features without having adl. |
|
- Properly check shares against target difficulty - This will no longer show |
|
shares when solo mining at all unless they're considered to be a block solve. |
|
- Add altivec 4 way (cpu mining) support courtesy of Gilles Risch. |
|
- Try to use SSL if the server supports it. |
|
- Display the total solved blocks on exit (LOL if you're lucky). |
|
- Use ADL activity report to tell us if a sick GPU is still busy suggesting it |
|
is hard hung and do not attempt to restart it. |
|
|
|
|
|
Version 2.0.5 - September 27, 2011 |
|
|
|
- Intensity can now be set to dynamic or static values per-device. |
|
- New donation feature --donation sends a proportion of shares to author's |
|
account of choice, but is disabled by default! |
|
- The hash being displayed and block detection has been fixed. |
|
- Devices not being mined on will not attempt to be ADL managed. |
|
- Intensity is now displayed per GPU device. |
|
- Make longpoll attempt to restart as often as opt_retries specifies. |
|
- We weren't rolling work as often as we could. |
|
- Correct some memory management issues. |
|
- Build fixes. |
|
- Don't mess with GPUs if we don't have them. |
|
|
|
|
|
Version 2.0.4 - September 23, 2011 |
|
|
|
- Confused Longpoll messages should be finally fixed with cgminer knowing for |
|
sure who found the new block and possibly avoiding a rare crash. |
|
- Display now shows the actual hash and will say BLOCK! if a block is deemed |
|
solved. |
|
- Extra spaces, which would double space lines on small terminals, have been |
|
removed. |
|
- Fan speed change is now damped if it is already heading in the correct |
|
direction to minimise overshoot. |
|
- Building without opencl libraries is fixed. |
|
- GPUs are autoselected if there is only one when in the GPU management menu. |
|
- GPU menu is refreshed instead of returning to status after a GPU change. |
|
|
|
|
|
Version 2.0.3 - September 17, 2011 |
|
|
|
- Various modes of failure to set fanspeeds and adl values have been addressed |
|
and auto-fan should work now on most hardware, and possibly other values |
|
which previously would not have worked. |
|
- Fixed a crash that can occur on switching pools due to longpoll thread races. |
|
- Use ATISTREAMSDKROOT if available at build time. |
|
- Fanspeed management is returned to the driver default on exit instead of |
|
whatever it was when cgminer was started. |
|
- Logging of events deemed WARNING or ERR now will display even during |
|
periods where menu input is being awaited on. |
|
|
|
|
|
Version 2.0.2 - September 11, 2011 |
|
|
|
- Exit cleanly if we abort before various threads are set up or if they no |
|
longer exist. |
|
- Fix a rare crash in HASH_DEL due to using different mutexes to protect the |
|
data. |
|
- Flag devices that have never started and don't allow enabling of devices |
|
without restarting them. |
|
- Only force the adapter speed to high if we've flagged this device as being |
|
managed. |
|
- Flag any devices with autofan or autogpu as being managed. |
|
- Use a re-entrant value to store what fanspeed we're trying to set in case the |
|
card doesn't support small changes. Force it to a multiple of 10% if it |
|
fails on trying to speed up the fan. |
|
- Do not bother resetting values to old ones if changes to GPU parameters report |
|
failure, instead returning a failure code only if the return value from get() |
|
differs. |
|
- Remove redundant check. |
|
- Only display supported values from fanspeed on change settings. |
|
- Missing bracket from output. |
|
- Display fan percentage on devices that only support reporting percent and not |
|
RPM. |
|
- Properly substitute DLOPEN flags to build with ADL support when -ldl is needed |
|
and not when opencl is not found. |
|
|
|
|
|
Version 2.0.1 - September 9, 2011 |
|
|
|
- Fix building on 32bit glibc with dlopen with -lpthread and -ldl |
|
- ByteReverse is not used and the bswap opcode breaks big endian builds. Remove |
|
it. |
|
- Ignore whether the display is active or not since only display enabled devices |
|
work this way, and we skip over repeat entries anwyay. |
|
- Only reset values on exiting if we've ever modified them. |
|
- Flag adl as active if any card is successfully activated. |
|
- Add a thermal cutoff option as well and set it to 95 degrees by default. |
|
- Change the fan speed by only 5% if it's over the target temperature but less |
|
than the hysteresis value to minimise overshoot down in temperature. |
|
- Add a --no-adl option to disable ADL monitoring and GPU settings. |
|
- Only show longpoll received delayed message at verbose level. |
|
- Allow temperatures greater than 100 degrees. |
|
- We should be passing a float for the remainder of the vddc values. |
|
- Implement accepting a range of engine speeds as well to allow a lower limit to |
|
be specified on the command line. |
|
- Allow per-device fan ranges to be set and use them in auto-fan mode. |
|
- Display which GPU has overheated in warning message. |
|
- Allow temperature targets to be set on a per-card basis on the command line. |
|
- Display fan range in autofan status. |
|
- Setting the hysteresis is unlikely to be useful on the fly and doesn't belong |
|
in the per-gpu submenu. |
|
- With many cards, the GPU summaries can be quite long so use a terse output |
|
line when showing them all. |
|
- Use a terser device status line to show fan RPM as well when available. |
|
- Define max gpudevices in one macro. |
|
- Allow adapterid 0 cards to enumerate as a device as they will be non-AMD |
|
cards, and enable ADL on any AMD card. |
|
- Do away with the increasingly confusing and irrelevant total queued and |
|
efficiency measures per device. |
|
- Only display values in the log if they're supported and standardise device log |
|
line printing. |
|
|
|
|
|
Version 2.0.0 - September 6, 2011 |
|
|
|
Major feature upgrade - GPU monitoring, (over)clocking and fan control for ATI |
|
GPUs. |
|
|
|
New command line switches: |
|
--auto-fan- Automatically adjust all GPU fan speeds to maintain a target |
|
temperature |
|
--auto-gpu- Automatically adjust all GPU engine clock speeds to maintain |
|
a target temperature |

fan and GPU speeds (default: 85) |
|
--temp-target <arg> Set the target temperature when automatically managing fan |
|
and GPU speeds (default: 75) |
|
|
|
- Implement ATI ADL support for GPU parameter monitoring now and setting later |
|
(temp, fan, clocks etc.). |
|
- Check for the presence of the ADL header files in ADL_SDK. |
|
- Import adl_functions.h from amd overdrive ctrl. |
|
- Implement a setup function that tries to detect GPUs that support the ADL and |
|
link in the parameters into the gpus struct. |
|
- Put a summary of monitoring information from the GPU menu. |
|
- Implement changing memory speed and voltage on the fly. |
|
- Implement fan speed setting. |
|
- Minor corrections to set fan speed by percentage. |
|
- Make sure to read off the value in RPM only. |
|
- Implement auto fanspeed adjustment to maintain a target temperature and |
|
fanspeed below 85%, with an overheat check that will speed the fan up to 100%. |
|
- Add an --auto-fan command line option to allow all GPUs to have autofan |
|
enabled from startup. |
|
- Add a gpu autotune option which adjusts GPU speed to maintain a target |
|
temperature within the bounds of the default GPU speed and any overclocking set. |
|
- Avoid a dereference if the longpoll thread doesn't exist. |
|
- Clean up by setting performance profiles and fan settings to startup levels on |
|
exit. |
|
- Add a small amount of hysteresis before lowering clock speed. |
|
- Allow target, overheat and hysteresis temperatures to be set from command |
|
line. |
|
- Combine all stats collating into one function to avoid repeating function |
|
calls on each variable. |
|
- Add gpu statistics to debugging output via the watchdog thread. |
|
- Implement menus to change temperature limits. |
|
- Implement setting the GPU engine clock speed of all devices or each device as |
|
a comma separated value. |
|
- Implement setting the GPU memory clock speed of all devices or each device as |
|
a comma separated value. |
|
- Implement setting the GPU voltage of all devices or each device as a comma |
|
separated value. |
|
- Implement setting the GPU fan speed of all devices or each device as a comma |
|
separated value. |
|
- Add support for monitoring powertune setting. |
|
- Implement changing of powertune value from the GPU change settings menu. |
|
- Get the value of powertune in get_stats. |
|
- Implement setting the GPU powertune value of all devices or each device as a |
|
comma separated value. |
|
- Remove the safety checks in speed setting since confirmation is done first in |
|
the menu, then show the new current values after a short pause. |
|
- Force the speed to high on startup and restore it to whatever the setting was |
|
on exit. |
|
- Add temperature to standard output where possible and use more compact output. |
|
- Move and print at the same time in curses to avoid random trampling display |
|
errors. |
|
- Update the status window only from the watchdog thread, do not rewrite the top |
|
status messages and only refresh once all the status window is complete, |
|
clearing the window each time to avoid corruption. |
|
- Set a safe starting fan speed if we're automanaging the speeds. |
|
- Provide locking around all adl calls to prevent races. |
|
- Lower profile settings cannot be higher than higher profile ones so link any |
|
drops in settings. |
|
- Add new needed text files to distribution. |
|
- Queue requests ignoring the number of staged clones since they get discarded |
|
very easily leading to false positives for pool not providing work fast enough. |
|
- Include libgen.h in opt.c to fix win32 compilation warnings. |
|
- Fix compilation warning on win32. |
|
- Add the directory name from the arguments cgminer was called from as well to |
|
allow it running from a relative pathname. |
|
- Add a --disable-adl option to configure and only enable it if opencl support |
|
exists. |
|
- Retry before returning a failure to get upstream work as a failure to avoid |
|
false positives for pool dead. |
|
- Retry also if the decoding of work fails. |
|
- Use the presence of X-Roll-Ntime in the header as a bool for exists unless N |
|
is found in the response. |
|
|
|
|
|
Version 1.6.2 - September 2, 2011 |
|
|
|
- Add --failover-only option to not leak work to backup pools when the primary |
|
pool is lagging. |
|
- Change recommendation to intensity 9 for dedicated miners. |
|
- Fix the bouncing short term value by allowing it to change dynamically when |
|
the latest value is very different from the rolling value, but damp the change |
|
when it gets close. |
|
- Use the curses_lock to protect the curses_active variable and test it under |
|
lock. |
|
- Go back to requesting work 2/3 of the way through the current scantime with |
|
CPU mining as reports of mining threads running out of work have occurred with |
|
only 5 seconds to retrieve work. |
|
- Add start and stop time scheduling for regular time of day running or once off |
|
start/stop options. |
|
- Print summary on quit modes. |
|
- Put some sanity checks on the times that can be input. |
|
- Give a verbose message when no active pools are found and pause before |
|
exiting. |
|
- Add verbose message when a GPU fails to initialise, and disable the correct |
|
GPU. |
|
- Cryptopp asm32 was not correctly updated to the incremental nonce code so the |
|
hash counter was bogus. |
|
- Get rid of poorly executed curl check. |
|
- If curl does not have sockopts, do not try to compile the |
|
json_rpc_call_sockopt_cb function, making it possible to build against older |
|
curl libraries. |
|
- Most people expect /usr/local when an unspecified prefix is used so change to |
|
that. |
|
- Rename localgen occasions to getwork fail occasions since localgen is |
|
unrelated now. |
|
|
|
|
|
Version 1.6.1 - August 29, 2011 |
|
|
|
- Copy cgminer path, not cat it. |
|
- Switching between redrawing windows does not fix the crash with old |
|
libncurses, so redraw both windows, but only when the window size hasn't |
|
changed. |
|
- Reinstate minimum 1 extra in queue to make it extremely unlikely to ever have |
|
0 staged work items and any idle time. |
|
- Return -1 if no input is detected from the menu to prevent it being |
|
interpreted as a 0. |
|
- Make pthread, libcurl and libcurses library checks mandatory or fail. |
|
- Add a --disable-opencl configure option to make it possible to override |
|
detection of opencl and build without GPU mining support. |
|
- Confusion over the variable name for number of devices was passing a bogus |
|
value which likely was causing the zero sized binary issue. |
|
- cgminer no longer supports default url user and pass so remove them. |
|
- Don't show value of intensity since it's dynamic by default. |
|
- Add options to explicitly enable CPU mining or disable GPU mining. |
|
- Convert the opt queue into a minimum number of work items to have queued |
|
instead of an extra number to decrease risk of getting idle devices without |
|
increasing risk of higher rejects. |
|
- Statify tv_sort. |
|
- Check for SSE2 before trying to build 32 bit SSE2 assembly version. Prevents |
|
build failure when yasm is installed but -msse2 is not specified. |
|
- Add some defines to configure.ac to enable exporting of values and packaging, |
|
and clean up output. |
|
- Give convenient summary at end of ./configure. |
|
- Display version information and add --version command line option, and make |
|
sure we flush stdout. |
|
- Enable curses after the mining threads are set up so that failure messages |
|
won't be lost in the curses interface. |
|
- Disable curses after inputting a pool if we requested no curses interface. |
|
- Add an option to break out after successfully mining a number of accepted |
|
shares. |
|
- Exit with a failed return code if we did not reach opt_shares. |
|
- The cpu mining work data can get modified before we copy it if we submit it |
|
async, and the sync submission is not truly sync anyway, so just submit it sync. |
|
|
|
|
|
Version 1.6.0 - August 26, 2011 |
|
|
|
- Make restarting of GPUs optional for systems that hang on any attempt to |
|
restart them. Fix DEAD status by comparing it to last live time rather than |
|
last attempted restart time since that happens every minute. |
|
- Move staged threads to hashes so we can sort them by time. |
|
- Create a hash list of all the blocks created and search them to detect when a |
|
new block has definitely appeared, using that information to detect stale work |
|
and discard it. |
|
- Update configure.ac for newer autoconf tools. |
|
- Use the new hashes directly for counts instead of the fragile counters |
|
currently in use. |
|
- Update to latest sse2 code from cpuminer-ng. |
|
- Allow LP to reset block detect and block detect lp flags to know who really |
|
came first. |
|
- Get start times just before mining begins to not have very slow rise in |
|
average. |
|
- Add message about needing one server. |
|
- We can queue all the necessary work without hitting frequent stales now with |
|
the time and string stale protection active all the time. This prevents a |
|
pool being falsely labelled as not providing work fast enough. |
|
- Include uthash.h in distro. |
|
- Implement SSE2 32 bit assembly algorithm as well. |
|
- Fail gracefully if unable to open the opencl files. |
|
- Make cgminer look in the install directory for the .cl files making make |
|
install work correctly. |
|
- Allow a custom kernel path to be entered on the command line. |
|
- Bump threshhold for lag up to maximum queued but no staged work. |
|
- Remove fragile source patching for bitalign, vectors et. al and simply pass it |
|
with the compiler options. |
|
- Actually check the value returned for the x-roll-ntime extension to make sure |
|
it isn't saying N. |
|
- Prevent segfault on exit for when accessory threads don't exist. |
|
- Disable curl debugging with opt protocol since it spews to stderr. |
|
|
|
|
|
Version 1.5.8 - August 23, 2011 |
|
|
|
- Minimise how much more work can be given in cpu mining threads each interval. |
|
- Make the fail-pause progressively longer each time it fails until the network |
|
recovers. |
|
- Only display the lagging message if we've requested the work earlier. |
|
- Clean up the pool switching to not be dependent on whether the work can roll |
|
or not by setting a lagging flag and then the idle flag. |
|
- Only use one thread to determine if a GPU is sick or well, and make sure to |
|
reset the sick restart attempt time. |
|
- The worksize was unintentionally changed back to 4k by mistake, this caused a |
|
slowdown. |
|
|
|
|
|
Version 1.5.7 - August 22, 2011 |
|
|
|
- Fix a crash with --algo auto |
|
- Test at appropriate target difficulty now. |
|
- Add per-device statics log output with --per-device-stats |
|
- Fix breakage that occurs when 1 or 4 vectors are chosen on new phatk. |
|
- Make rolltime report debug level only now since we check it every work |
|
item. |
|
- Add the ability to enable/disable per-device stats on the fly and match |
|
logging on/off. |
|
- Explicitly tell the compiler to retain the program to minimise the chance of |
|
the zero sized binary errors. |
|
- Add one more instruction to avoid one branch point in the common path in the |
|
cl return code. Although this adds more ALUs overall and more branch points, the |
|
common path code has the same number of ALUs and one less jmp, jmps being more |
|
expensive. |
|
- Explicitly link in ws2_32 on the windows build and update README file on how |
|
to compile successfully on windows. |
|
- Release cl resources should the gpu mining thread abort. |
|
- Attempt to restart a GPU once every minute while it's sick. |
|
- Don't kill off the reinit thread if it fails to init a GPU but returns safely. |
|
- Only declare a GPU dead if there's been no sign of activity from the reinit |
|
thread for 10 mins. |
|
- Never automatically disable any pools but just specify them as idle if they're |
|
unresponsive at startup. |
|
- Use any longpoll available, and don't disable it if switching to a server that |
|
doesn't have it. This allows you to mine solo, yet use the longpoll from a pool |
|
even if the pool is the backup server. |
|
- Display which longpoll failed and don't free the ram for lp_url since it |
|
belongs to the pool hdr path. |
|
- Make the tcp setsockopts unique to linux in the hope it allows freebsd et. al |
|
to compile. |
|
|
|
|
|
Version 1.5.6 - August 17, 2011 |
|
|
|
- New phatk and poclbm kernels. Updated phatk to be in sync with latest 2.2 |
|
courtesy of phateus. Custom modified to work best with cgminer. |
|
- Updated output buffer code to use a smaller buffer with the kernels. |
|
- Clean up the longpoll management to ensure the right paths go to the right |
|
pool and display whether we're connected to LP or not in the status line. |
|
|
|
|
|
Version 1.5.5 - August 16, 2011 |
|
|
|
- Rework entirely the GPU restart code. Strike a balance between code that |
|
re-initialises the GPU entirely so that soft hangs in the code are properly |
|
managed, but if a GPU is completely hung, the thread restart code fails |
|
gracefully, so that it does not take out any other code or devices. This will |
|
allow cgminer to keep restarting GPUs that can be restarted, but continue |
|
mining even if one or more GPUs hangs which would normally require a reboot. |
|
- Add --submit-stale option which submits all shares, regardless of whether they |
|
would normally be considered stale. |
|
- Keep options in alphabetical order. |
|
- Probe for slightly longer for when network conditions are lagging. |
|
- Only display the CPU algo when we're CPU mining. |
|
- As we have keepalives now, blaming network flakiness on timeouts appears to |
|
have been wrong. Set a timeout for longpoll to 1 hour, and most other |
|
network connectivity to 1 minute. |
|
- Simplify output code and remove HW errors from CPU stats. |
|
- Simplify code and tidy output. |
|
- Only show cpu algo in summary if cpu mining. |
|
- Log summary at the end as per any other output. |
|
- Flush output. |
|
- Add a linux-usb-cgminer guide courtesy of Kano. |
|
|
|
|
|
Version 1.5.4 - August 14, 2011 |
|
|
|
- Add new option: --monitor <cmd> Option lets user specify a command <cmd> that |
|
will get forked by cgminer on startup. cgminer's stderr output subsequently gets |
|
piped directly to this command. |
|
- Allocate work from one function to be able to initialise variables added |
|
later. |
|
- Add missing fflush(stdout) for --ndevs and conclusion summary. |
|
- Preinitialise the devices only once on startup. |
|
- Move the non cl_ variables into the cgpu info struct to allow creating a new |
|
cl state on reinit, preserving known GPU variables. |
|
- Create a new context from scratch in initCQ in case something was corrupted to |
|
maximise our chance of succesfully creating a new worker thread. Hopefully this |
|
makes thread restart on GPU failure more reliable, without hanging everything |
|
in the case of a completely wedged GPU. |
|
- Display last initialised time in gpu management info, to know if a GPU has |
|
been re-initialised. |
|
- When pinging a sick cpu, flush finish and then ping it in a separate thread in |
|
the hope it recovers without needing a restart, but without blocking code |
|
elsewhere. |
|
- Only consider a pool lagging if we actually need the work and we have none |
|
staged despite queue requests stacking up. This decreases significantly the |
|
amount of work that leaks to the backup pools. |
|
- The can_roll function fails inappropriately in stale_work. |
|
- Only put the message that a pool is down if not pinging it every minute. This |
|
prevents cgminer from saying pool down at 1 minute intervals unless in debug |
|
mode. |
|
- Free all work in one place allowing us to perform actions on it in the future. |
|
- Remove the extra shift in the output code which was of dubious benefit. In |
|
fact in cgminer's implementation, removing this caused a miniscule speedup. |
|
- Test each work item to see if it can be rolled instead of per-pool and roll |
|
whenever possible, adhering to the 60 second timeout. This makes the period |
|
after a longpoll have smaller dips in throughput, as well as requiring less |
|
getworks overall thus increasing efficiency. |
|
- Stick to rolling only work from the current pool unless we're in load balance |
|
mode or lagging to avoid aggressive rolling imitating load balancing. |
|
- If a work item has had any mining done on it, don't consider it discarded |
|
work. |
|
|
|
|
|
Version 1.5.3 - July 30, 2011 |
|
|
|
- Significant work went into attempting to make the thread restart code robust |
|
to identify sick threads, tag them SICK after 1 minute, then DEAD after 5 |
|
minutes of inactivity and try to restart them. Instead of re-initialising the |
|
GPU completely, only a new cl context is created to avoid hanging the rest of |
|
the GPUs should the dead GPU be hung irrevocably. |
|
- Use correct application name in syslog. |
|
- Get rid of extra line feeds. |
|
- Use pkg-config to check for libcurl version |
|
- Implement per-thread getwork count with proper accounting to not over-account |
|
queued items when local work replaces it. |
|
- Create a command queue from the program created from source which allows us |
|
to flush the command queue in the hope it will not generate a zero sized binary |
|
any more. |
|
- Be more willing to get work from the backup pools if the work is simply being |
|
queued faster than it is being retrieved. |
|
|
|
|
|
Version 1.5.2 - July 28, 2011 |
|
|
|
- Restarting a hung GPU can hang the rest of the GPUs so just declare it dead |
|
and provide the information in the status. |
|
- The work length in the miner thread gets smaller but doesn't get bigger if |
|
it's under 1 second. This could end up leading to CPU under-utilisation and |
|
lower and lower hash rates. Fix it by increasing work length if it drops |
|
under 1 second. |
|
- Make the "quiet" mode still update the status and display errors, and add a |
|
new --real-quiet option which disables all output and can be set once while |
|
running. |
|
- Update utility and efficiency figures when displaying them. |
|
- Some Intel HD graphics support the opencl commands but return errors since |
|
they don't support opencl. Don't fail with them, just provide a warning and |
|
disable GPU mining. |
|
- Add http:// if it's not explicitly set for URL entries. |
|
- Log to the output file at any time with warnings and errors, instead of just |
|
when verbose mode is on. |
|
- Display the correct current hash as per blockexplorer, truncated to 16 |
|
characters, with just the time. |
|
|
|
|
|
Version 1.5.1 - July 27, 2011 |
|
|
|
- Two redraws in a row cause a crash in old libncurses so just do one redraw |
|
using the main window. |
|
- Don't adjust hash_div only up for GPUs. Disable hash_div adjustment for GPUs. |
|
- Only free the thread structures if the thread still exists. |
|
- Update both windows separately, but not at the same time to prevent the double |
|
refresh crash that old libncurses has. Do the window resize check only when |
|
about to redraw the log window to minimise ncurses cpu usage. |
|
- Abstract out the decay time function and use it to make hash_div a rolling |
|
average so it doesn't change too abruptly and divide work in chunks large enough |
|
to guarantee they won't overlap. |
|
- Sanity check to prove locking. |
|
- Don't take more than one lock at a time. |
|
- Make threads report out when they're queueing a request and report if they've |
|
failed. |
|
- Make cpu mining work submission asynchronous as well. |
|
- Properly detect stale work based on time from staging and discard instead of |
|
handing on, but be more lax about how long work can be divided for up to the |
|
scantime. |
|
- Do away with queueing work separately at the start and let each thread grab |
|
its own work as soon as it's ready. |
|
- Don't put an extra work item in the queue as each new device thread will do so |
|
itself. |
|
- Make sure to decrease queued count if we discard the work. |
|
- Attribute split work as local work generation. |
|
- If work has been cloned it is already at the head of the list and when being |
|
reinserted into the queue it should be placed back at the head of the list. |
|
- Dividing work is like the work is never removed at all so treat it as such. |
|
However the queued bool needs to be reset to ensure we *can* request more work |
|
even if we didn't initially. |
|
- Make the display options clearer. |
|
- Add debugging output to tq_push calls. |
|
- Add debugging output to all tq_pop calls. |
|
|
|
|
|
Version 1.5.0 - July 26, 2011 |
|
|
|
- Increase efficiency of slow mining threads such as CPU miners dramatically. Do |
|
this by detecting which threads cannot complete searching a work item within the |
|
scantime and then divide up a work item into multiple smaller work items. |
|
Detect the age of the work items and if they've been cloned before to prevent |
|
doing the same work over. If the work is too old to be divided, then see if it |
|
can be time rolled and do that to generate work. This dramatically decreases the |
|
number of queued work items from a pool leading to higher overall efficiency |
|
(but the same hashrate and share submission rate). |
|
- Don't request work too early for CPUs as CPUs will scan for the full |
|
opt_scantime anyway. |
|
- Simplify gpu management enable/disable/restart code. |
|
- Implement much more accurate rolling statistics per thread and per gpu and |
|
improve accuracy of rolling displayed values. |
|
- Make the rolling log-second average more accurate. |
|
- Add a menu to manage GPUs on the fly allowing you to enable/disable GPUs or |
|
try restarting them. |
|
- Keep track of which GPUs are alive versus enabled. |
|
- Start threads for devices that are even disabled, but don't allow them to |
|
start working. |
|
- The last pool is when we are low in total_pools, not active_pools. |
|
- Make the thread restart do a pthread_join after disabling the device, only |
|
re-enabling it if we succeed in restarting the thread. Do this from a separate |
|
thread so as to not block any other code.This will allow cgminer to continue |
|
even if one GPU hangs. |
|
- Try to do every curses manipulation under the curses lock. |
|
- Only use the sockoptfunction if the version of curl is recent enough. |
|
|
|
|
|
Version 1.4.1 - July 24, 2011 |
|
|
|
- Do away with GET for dealing with longpoll forever. POST is the one that works |
|
everywhere, not the other way around. |
|
- Detect when the primary pool is lagging and start queueing requests on backup |
|
pools if possible before needing to roll work. |
|
- Load balancing puts more into the current pool if there are disabled pools. |
|
Fix. |
|
- Disable a GPU device should the thread fail to init. |
|
- Out of order command queue may fail on osx. Try without if it fails. |
|
- Fix possible dereference on blank inputs during input_pool. |
|
- Defines missing would segfault on --help when no sse mining is built in. |
|
- Revert "Free up resources/stale compilers." - didn't help. |
|
- Only try to print the status of active devices or it would crash. |
|
- Some hardware might benefit from the less OPS so there's no harm in leaving |
|
kernel changes that do that apart from readability of the code. |
|
|
|
Version 1.4.0 - July 23, 2011 |
|
|
|
- Feature upgrade: Add keyboard input during runtime to allow modification of |
|
and viewing of numerous settings such as adding/removing pools, changing |
|
multipool management strategy, switching pools, changing intensiy, verbosity, |
|
etc. with a simple keypress menu system. |
|
- Free up resources/stale compilers. |
|
- Kernels are safely flushed in a way that allows out of order execution to |
|
work. |
|
- Sometimes the cl compiler generates zero sized binaries and only a reboot |
|
seems to fix it. |
|
- Don't try to stop/cancel threads that don't exist. |
|
- Only set option to show devices and exit if built with opencl support. |
|
- Enable curses earlier and exit with message in main for messages to not be |
|
lost in curses windows. |
|
- Make it possible to enter server credentials with curses input if none are |
|
specified on the command line. |
|
- Abstract out a curses input function and separate input pool function to allow |
|
for live adding of pools later. |
|
- Remove the nil arguments check to allow starting without parameters. |
|
- Disable/enable echo & cbreak modes. |
|
- Add a thread that takes keyboard input and allow for quit, silent, debug, |
|
verbose, normal, rpc protocol debugging and clear screen options. |
|
- Add pool option to input and display current pool status, pending code to |
|
allow live changes. |
|
- Add a bool for explicit enabling/disabling of pools. |
|
- Make input pool capable of bringing up pools while running. |
|
- Do one last check of the work before submitting it. |
|
- Implement the ability to live add, enable, disable, and switch to pools. |
|
- Only internally test for block changes when the work matches the current pool |
|
to prevent interleaved block change timing on multipools. |
|
- Display current pool management strategy to enable changing it on the fly. |
|
- The longpoll blanking of the current_block data may not be happening before |
|
the work is converted and appears to be a detected block change. Blank the |
|
current block be |
|
- Make --no-longpoll work again. |
|
- Abstract out active pools count. |
|
- Allow the pool strategy to be modified on the fly. |
|
- Display pool information on the fly as well. |
|
- Add a menu and separate out display options. |
|
- Clean up the messy way the staging thread communicates with the longpoll |
|
thread to determine who found the block first. |
|
- Make the input windows update immediately instead of needing a refresh. |
|
- Allow log interval to be set in the menu. |
|
- Allow scan settings to be modified at runtime. |
|
- Abstract out the longpoll start and explicitly restart it on pool change. |
|
- Make it possible to enable/disable longpoll. |
|
- Set priority correctly on multipools. Display priority and alive/dead |
|
information in display_pools. |
|
- Implement pool removal. |
|
- Limit rolltime work generation to 10 iterations only. |
|
- Decrease testing log to info level. |
|
- Extra refresh not required. |
|
- With huge variation in GPU performance, allow intensity to go from -10 to +10. |
|
- Tell getwork how much of a work item we're likely to complete for future |
|
splitting up of work. |
|
- Remove the mandatory work requirement at startup by testing for invalid work |
|
being passed which allows for work to be queued immediately. This also |
|
removes the requirem |
|
- Make sure intensity is carried over to thread count and is at least the |
|
minimum necessary to work. |
|
- Unlocking error on retry. Locking unnecessary anyway so remove it. |
|
- Clear log window from consistent place. No need for locking since logging is |
|
disabled during input. |
|
- Cannot print the status of threads that don't exist so just queue enough work |
|
for the number of mining threads to prevent crash with -Q N. |
|
- Update phatk kernel to one with new parameters for slightly less overhead |
|
again. Make the queue kernel parameters call a function pointer to select |
|
phatk or poclbm. |
|
- Make it possible to select the choice of kernel on the command line. |
|
- Simplify the output part of the kernel. There's no demonstrable advantage from |
|
more complexity. |
|
- Merge pull request #18 from ycros/cgminer |
|
- No need to make leaveok changes win32 only. |
|
- Build support in for all SSE if possible and only set the default according to |
|
machine capabilities. |
|
- Win32 threading and longpoll keepalive fixes. |
|
- Win32: Fix for mangled output on the terminal on exit. |
|
|
|
|
|
Version 1.3.1 - July 20, 2011 |
|
|
|
- Feature upgrade; Multiple strategies for failover. Choose from default which |
|
now falls back to a priority order from 1st to last, round robin which only |
|
changes pools when one is idle, rotate which changes pools at user-defined |
|
intervals, and load-balance which spreads the work evenly amongst all pools. |
|
- Implement pool rotation strategy. |
|
- Implement load balancing algorithm by rotating requests to each pool. |
|
- Timeout on failed discarding of staged requests. |
|
- Implement proper flagging of idle pools, test them with the watchdog thread, |
|
and failover correctly. |
|
- Move pool active test to own function. |
|
- Allow multiple strategies to be set for multipool management. |
|
- Track pool number. |
|
- Don't waste the work items queued on testing the pools at startup. |
|
- Reinstate the mining thread watchdog restart. |
|
- Add a getpoll bool into the thread information and don't restart threads stuck |
|
waiting on work. |
|
- Rename the idlenet bool for the pool for later use. |
|
- Allow the user/pass userpass urls to be input in any order. |
|
- When json rpc errors occur they occur in spits and starts, so trying to limit |
|
them with the comms error bool doesn't stop a flood of them appearing. |
|
- Reset the queued count to allow more work to be queued for the new pool on |
|
pool switch. |
|
|
|
Version 1.3.0 - July 19, 2011 |
|
|
|
- Massive infrastructure update to support pool failover. |
|
- Accept multiple parameters for url, user and pass and set up structures of |
|
pool data accordingly. |
|
- Probe each pool for what it supports. |
|
- Implement per pool feature support according to rolltime support as |
|
advertised by server. |
|
- Do switching automatically based on a 300 second timeout of locally generated |
|
work or 60 seconds of no response from a server that doesn't support rolltime. |
|
- Implement longpoll server switching. |
|
- Keep per-pool data and display accordingly. |
|
- Make sure cgminer knows how long the pool has actually been out for before |
|
deeming it a prolonged outage. |
|
- Fix bug with ever increasing staged work in 1.2.8 that eventually caused |
|
infinite rejects. |
|
- Make warning about empty http requests not show by default since many |
|
servers do this regularly. |
|
|
|
|
|
Version 1.2.8 - July 18, 2011 |
|
|
|
- More OSX build fixes. |
|
- Add an sse4 algorithm to CPU mining. |
|
- Fix CPU mining with other algorithms not working. |
|
- Rename the poclbm file to ensure a new binary is built since. |
|
- We now are guaranteed to have one fresh work item after a block change and we |
|
should only discard staged requests. |
|
- Don't waste the work we retrieve from a longpoll. |
|
- Provide a control lock around global bools to avoid racing on them. |
|
- Iterating over 1026 nonces when confirming data from the GPU is old code |
|
and unnecessary and can lead to repeats/stales. |
|
- The poclbm kernel needs to be updated to work with the change to 4k sized |
|
output buffers. |
|
- longpoll seems to work either way with post or get but some servers prefer |
|
get so change to httpget. |
|
|
|
|
|
Version 1.2.7 - July 16, 2011 |
|
|
|
- Show last 8 characters of share submitted in log. |
|
- Display URL connected to and user logged in as in status. |
|
- Display current block and when it was started in the status line. |
|
- Only pthread_join the mining threads if they exist as determined by |
|
pthread_cancel and don't fail on pthread_cancel. |
|
- Create a unique work queue for all getworks instead of binding it to thread 0 |
|
to avoid any conflict over thread 0's queue. |
|
- Clean up the code to make it clear it's watchdog thread being messaged to |
|
restart the threads. |
|
- Check the current block description hasn't been blanked pending the real |
|
new current block data. |
|
- Re-enable signal handlers once the signal has been received to make it |
|
possible to kill cgminer if it fails to shut down. |
|
- Disable restarting of CPU mining threads pending further investigation. |
|
- Update longpoll messages. |
|
- Add new block data to status line. |
|
- Fix opencl tests for osx. |
|
- Only do local generation of work if the work item is not stale itself. |
|
- Check for stale work within the mining threads and grab new work if |
|
positive. |
|
- Test for idle network conditions and prevent threads from being restarted |
|
by the watchdog thread under those circumstances. |
|
- Make sure that local work generation does not continue indefinitely by |
|
stopping it after 10 minutes. |
|
- Tweak the kernel to have a shorter path using a 4k buffer and a mask on the |
|
nonce value instead of a compare and loop for a shorter code path. |
|
- Allow queue of zero and make that default again now that we can track how |
|
work is being queued versus staged. This can decrease reject rates. |
|
- Queue precisely the number of mining threads as longpoll_staged after a |
|
new block to not generate local work. |
|
|

Version 1.2.6 - July 15, 2011 |
|
|
|
- Put a current system status line beneath the total work status line |
|
- Fix a counting error that would prevent cgminer from correctly detecting |
|
situations where getwork was failing - this would cause stalls sometimes |
|
unrecoverably. |
|
- Limit the maximum number of requests that can be put into the queue which |
|
otherwise could get arbitrarily long during a network outage. |
|
- Only count getworks that are real queue requests. |
|
|
|
|
|
Version 1.2.5 - July 15, 2011 |
|
|
|
- Conflicting -n options corrected |
|
- Setting an intensity with -I disables dynamic intensity setting |
|
- Removed option to manually disable dynamic intensity |
|
- Improve display output |
|
- Implement signal handler and attempt to clean up properly on exit |
|
- Only restart threads that are not stuck waiting on mandatory getworks |
|
- Compatibility changes courtesy of Ycros to build on mingw32 and osx |
|
- Explicitly grab first work item to prevent false positive hardware errors |
|
due to working on uninitialised work structs |
|
- Add option for non curses --text-only output |
|
- Ensure we connect at least once successfully before continuing to retry to |
|
connect in case url/login parameters were wrong |
|
- Print an executive summary when cgminer is terminated |
|
- Make sure to refresh the status window |
|
|

|
|
- Make --user, --pass actually work |
|
|
|

|
more easily identify the miner client. |
|
|
|

|
|
|

|
|
|
Version 0.7.2 - March 14, 2011 |
|
|
|
- Add port of ufasoft's sse2 assembly implementation (Linux only) |
|
This is a substantial speed improvement on Intel CPUs. |
|
|
|
- Move all JSON-RPC I/O to separate thread. This reduces the |
|
number of HTTP connections from one-per-thread to one, reducing resource |
|
usage on upstream bitcoind / pool server. |
|
|
|
Version 0.7.1 - March 2, 2011 |
|
|
|
- Add support for JSON-format configuration file. See example |
|
file example-cfg.json. Any long argument on the command line |
|
may be stored in the config file. |
|
- Timestamp each solution found |
|
- Improve sha256_4way performance. NOTE: This optimization makes |
|
the 'hash' debug-print output for sha256_way incorrect. |
|
- Use __builtin_expect() intrinsic as compiler micro-optimization |
|
- Build on Intel compiler |
|
- HTTP library now follows HTTP redirects |
|
|
|
Version 0.7 - February 12, 2011 |
|
|
|
- Re-use CURL object, thereby reuseing DNS cache and HTTP connections |
|
- Use bswap_32, if compiler intrinsic is not available |
|
- Disable full target validation (as opposed to simply H==0) for now |
|
|
|
Version 0.6.1 - February 4, 2011 |
|
|
|
- Fully validate "hash < target", rather than simply stopping our scan |
|
if the high 32 bits are 00000000. |
|
- Add --retry-pause, to set length of pause time between failure retries |
|
- Display proof-of-work hash and target, if -D (debug mode) enabled |
|
- Fix max-nonce auto-adjustment to actually work. This means if your |
|
scan takes longer than 5 seconds (--scantime), the miner will slowly |
|
reduce the number of hashes you work on, before fetching a new work unit. |
|
|
|
Version 0.6 - January 29, 2011 |
|
|
|
- Fetch new work unit, if scanhash takes longer than 5 seconds (--scantime) |
