Version 2.5.0 - July 6, 2012 |
|
|
|
|
|
|
|
|
|
- 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 |
|
|
|

|
|
|
