Con Kolivas 0d676346 2012-08-05T16:15:32 Style cleanups.
Con Kolivas 31b01c8a 2012-08-05T16:13:53 Author: Luke Dashjr <luke-jr+git@utopios.org> Date: Thu Jul 12 16:49:26 2012 +0000 Use FTD2XX.DLL on Windows to autodetect BitFORCE SHA256 devices
Con Kolivas 245552c5 2012-08-03T09:49:14 Clear the bitforce buffer whenever we get an unexpected result as it has likely throttled and we are getting cached responses out of order, and use the temperature monitoring as a kind of watchdog to flush unexpected results.
Con Kolivas 7fa794a4 2012-08-03T09:26:43 It is not critical getting the temperature response in bitforce so don't mandatorily wait on the mutex lock.
Con Kolivas 5118e3ee 2012-08-03T08:12:05 Check there is a cutoff temp actually set in bitforce before using it as a cut off value otherwise it may think it's set to zero degrees.

Luke Dashjr d4af2d05 2012-07-06T02:39:32 Turn work_restart array into a bool in thr_info
Con Kolivas e97adc91 2012-07-06T15:09:39 The fastest minirig devices need a significantly smaller starting sleep time.
Con Kolivas 74b96d4b 2012-07-06T15:05:38 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.
Con Kolivas 13cf5689 2012-07-06T15:03:31 Use nmsleep instead of usleep in bitforce.
Con Kolivas 390d77a2 2012-07-06T10:41:08 Add more comments explaining how sleep time equals wait time and simplify the comparison.
Con Kolivas 69a11508 2012-07-06T10:35:18 delay_time_ms is always set so need not be initialised in bitforce.

Con Kolivas a3faf63c 2012-07-06T09:54:27 Add more hysteresis and poll ~5 times to allow for timer delays in bitforce devices.
Con Kolivas afc6ae58 2012-07-05T22:42:04 Change message about broken nonce range support to verbose level instead of debug.
Con Kolivas 86ba7d79 2012-07-05T22:39:41 Display the actual duration of wait when it is greater than the cutoff.
Con Kolivas 5a096c1c 2012-07-05T22:39:11 Set nonce to maximum once we determine nonce range support is broken.
Con Kolivas 88dd599f 2012-07-05T22:33:21 Initial wait time is always known so no need to zero it beforehand in bitforce.
Con Kolivas 1b0a0ac5 2012-07-05T22:32:05 No point counting wait time until the work is actually sent to bitforce devices.
Con Kolivas c0c48060 2012-07-05T21:51:42 Use string comparison functions elsewhere in bitforce code.
Con Kolivas d4e526c9 2012-07-05T21:29:06 Use string comparison functions instead of explicit comparisons.

Con Kolivas 8766bca4 2012-07-04T23:57:54 Queue extra work at 2/3 differently depending on whether we're using nonce range or not.
Con Kolivas 6314a12b 2012-07-04T23:53:55 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.

Paul Sheppard 6e6029de 2012-07-03T10:22:11 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.
Kano ff0afb94 2012-07-03T13:14:30 Add API Notify counter 'Comms Error'
Con Kolivas 44726324 2012-07-03T11:09:33 More style police on bitforce.

ckolivas 391e1f7e 2012-07-02T16:13:53 Restart is zeroed in the mining thread so no need to do it inside the bitforce code.
Paul Sheppard 04a6c3b1 2012-07-01T21:47:18 More improvements to comms. BFL return nothing when throttling, so should not be considered an error. Instead repeat with a longer delay.
ckolivas efcce5bb 2012-07-02T11:30:20 Remove unused tdiff value.
ckolivas b1cdacde 2012-07-02T11:28:26 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.
ckolivas fd7b21ed 2012-07-02T10:54:20 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.
Paul Sheppard 855d1bb3 2012-07-01T17:35:53 Add busy time to wait time.
Paul Sheppard a11a322b 2012-06-30T20:45:08 Add tiny delay after writing to BFL Change BFL errors to something more human readable Send work busy re-tries after 10ms delay
Paul Sheppard adc26f0e 2012-06-29T17:20:57 Add facility to clear BFL read buffer. Reduce timeout to 10s.
