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. 2012-07-04 23:53:55 +10:00

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.

391e1f7eb1 Restart is zeroed in the mining thread so no need to do it inside the bitforce code. 2012-07-02 16:13:53 +10:00

04a6c3b188 More improvements to comms. 
BFL return nothing when throttling, so should not be considered an error. Instead repeat with a longer delay.

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. 2012-07-02 11:28:26 +10:00
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. 2012-07-02 10:54:20 +10:00

d3e2b62c54 Change sick/dead processing to use device pointer, not gpu array.

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.

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.
