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.
|
|
|
|
|

|
|
|
|
- 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
|
|
|
|

|
|
|
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

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
|
|
|
|
|
- api.c escape required characters in return strings + pools returns the
|
|
|
|
|
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)
|
|
|
|
|
- miner.php highlight any device that isn't 'Enabled'
|
|
|
|
|
- miner.php highlight any Status that isn't 'Alive'
|
|
|
|
|
- miner.php optionally support multiple rigs
|
|
|
|
|
- Initial Ztex support 1.15x board.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
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 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
|
|

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.

|
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.

|
|
|
|
|
GPUs.
|
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
- 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.
|
|
|

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
|
|

|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
|
|
Version 0.8.1 - March 22, 2011
|
|
|
|
|
|
|
|
|
|
- Make --user, --pass actually work
|
|
|
|
|
|
|
|
|
|
- Add User-Agent HTTP header to requests, so that server operators may
|
|
|
|
|
more easily identify the miner client.
|
|
|
|
|
|
|
|
|
|
- Fix minor bug in example JSON config file
|
|
|
|
|
|
|
|
|
|
Version 0.8 - March 21, 2011
|
|
|
|
|
|
|
|
|
|
- Support long polling: http://deepbit.net/longpolling.php
|
|
|
|
|
|
|
|
|
|
- Adjust max workload based on scantime (default 5 seconds,
|
|
|
|
|
or 60 seconds for longpoll)
|
|
|
|
|
|
|
|
|
|
- Standardize program output, and support syslog on Unix platforms
|
|
|
|
|
|
|
|
|
|
- Suport --user/--pass options (and "user" and "pass" in config file),
|
|
|
|
|
as an alternative to the current --userpass
|
|
|
|
|
|
|
|
|
|
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
|
|
|
|
|
|
