Author	SHA1	Message	Date
Con Kolivas	8766bca4d4	Queue extra work at 2/3 differently depending on whether we're using nonce range or not.	13 years ago
Con Kolivas	6314a12b31	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.	13 years ago
Con Kolivas	96fba30b6b	Attempt to detect nonce range support in BFL by sending work requring its support.	13 years ago
Con Kolivas	a9746b9f5e	Limit retrying on busy for up to BITFORCE_TIMEOUT_MS	13 years ago
Con Kolivas	7046c976bc	Attempt to initialise while bitforce device returns BUSY.	13 years ago
Con Kolivas	ac8db06e46	Extend length of string that can be passed to BFL devices.	13 years ago
Con Kolivas	8b3c20bc06	Abstract out ms to timeval as a function.	13 years ago
Con Kolivas	93a7967ecb	Fix signedness warning.	13 years ago
Paul Sheppard	c4870676c4	Add api stats (sleep time)	13 years ago
Paul Sheppard	6e6029de99	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.	13 years ago
Kano	ff0afb94ec	Add API Notify counter 'Comms Error'	13 years ago
Con Kolivas	44726324c2	More style police on bitforce.	13 years ago
Con Kolivas	8783db0dc3	Do all logging outside of the bitforce mutex locking to avoid deadlocks.	13 years ago
Con Kolivas	0f405c7c18	Remove applog call from bfwrite to prevent grabbing nested mutexes.	13 years ago
Con Kolivas	978ec0d805	Bitforce style changes.	13 years ago
Paul Sheppard	ad5b470b04	Fine-tune timing adjustment. ... Also remove old work_restart timing.	13 years ago
ckolivas	391e1f7eb1	Restart is zeroed in the mining thread so no need to do it inside the bitforce code.	13 years ago
Paul Sheppard	04a6c3b188	More improvements to comms. ... BFL return nothing when throttling, so should not be considered an error. Instead repeat with a longer delay.	13 years ago
ckolivas	efcce5bbb8	Remove unused tdiff value.	13 years ago
ckolivas	b1cdacdead	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.	13 years ago
ckolivas	fd7b21ed56	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.	13 years ago
Paul Sheppard	855d1bb3e3	Add busy time to wait time.	13 years ago
Paul Sheppard	a11a322ba6	Add tiny delay after writing to BFL ... Change BFL errors to something more human readable Send work busy re-tries after 10ms delay	13 years ago
Paul Sheppard	adc26f0e3f	Add facility to clear BFL read buffer. ... Reduce timeout to 10s.	13 years ago
Paul Sheppard	75a651c13f	Revert "Check for submit_stale before checking for work_restart" ... Makes no sense to continue working on the old block whether submit_stale is enabled or not.	13 years ago
Paul Sheppard	f225392990	Add low hash threshold in sick/dead processing ... Add check for fd in comms procedures	13 years ago
Paul Sheppard	01a7e912c8	Lock comms around entire bitforce_init, and move setting of fd to end. ... Make sleep occur everytime in scanhash.	13 years ago
Paul Sheppard	d3e2b62c54	Change sick/dead processing to use device pointer, not gpu array. ... Change BFL timing to adjust only when hashing complete (not error/idle etc.).	13 years ago
Paul Sheppard	1ef52e0bac	Check for submit_stale before checking for work_restart ... (to keep Kano happy)	13 years ago
Paul Sheppard	f149aea91e	Redo recover removal. ... FML.	13 years ago
Paul Sheppard	90d82aa61d	Revert to pre pool merge	13 years ago
Paul Sheppard	50e996c753	Get rid of recover mode. Not useful at all. ... Change zero hash to no start error. Neither is accurate, but zero hash makes less sense than no start.	13 years ago
Paul Sheppard	9bc95ab30b	Comms error trapping ... Comms error will not disable the device permanently but put it in to recovery mode. Here it will attempt to be re-initialised after 60s.	13 years ago
Paul Sheppard	68f2aaf930	fix bitforce_init return value ... Also add filename as kernel name	13 years ago
Kano	4dee0d049c	FPGA - allow device detect override without an open failure	13 years ago
Paul Sheppard	4fd53c9eb1	thread init fix	13 years ago
Paul Sheppard	2ec612e0b4	Added startup delay to worker threads. ... Prevents devices from making calls at the same time.	13 years ago
Paul Sheppard	1b63a75d2c	Simple auto sleep-time calibration. ... Optimises the sleep time while waiting for the BFL work to finish. Takes ~5 mins to settle to the correct time for each unit, then will continue to make adjustments.	13 years ago
Paul Sheppard	2384d0fbc6	Removed idle mode... again!? ... Changed work_reset rate to every 100ms & use defines rather than numerics. Change total sleep time to 4300ms after performance testing/measurement (now good to 916MH/s). Changed timeout to 15s - Throttle time is 15s. Added support for 'Busy' when submitting work. Improved logging text to include device identifier. Added a thread_enable api function, called when a thread is re-enabled. ... and removed useless re-init inside scanhash. Use modminer introduced mutex.	13 years ago
Luke Dashjr	d3fa59d76f	Abstract generally useful FPGA code into fpgautils.c	13 years ago
Paul Sheppard	2dd7c4e1c0	Added checking of work_reset while waiting for BFL to return results	13 years ago
Paul Sheppard	820d662c9d	Removed idle mode. ... Added watchdog thread BFL temperature monitoring.	13 years ago
Paul Sheppard	036a97c21a	Added bitforce init and shutdown. ... bitforce_init closes/reopens the com port and re-initialises the unit.	13 years ago
Paul Sheppard	ec394533a2	Idle mode for bitforce	13 years ago
Paul Sheppard	ed06c97e2e	Added 30s BFL hashing timeout	13 years ago
Paul Sheppard	652326c2a1	Scanhash split into separate functions ... Some adjustment of log reporting	13 years ago
Paul Sheppard	8d2936730b	Fix return values	13 years ago
Paul Sheppard	cebd647f50	Messing with BFL code	13 years ago
