Roll back to init'ing bitforce devices at regular intervals. They may reinit more than previously thought. --- driver-bitforce.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) diff --git a/driver-bitforce.c b/driver-bitforce.c index 4606e29b..6a3f109f 100644 --- a/driver-bitforce.c +++ b/driver-bitforce.c @@ -525,6 +525,20 @@ static bool bitforce_get_stats(struct cgpu_info *bitforce) return bitforce_get_temp(bitforce); } +static bool bitforce_thread_init(struct thr_info *thr) +{ + struct cgpu_info *bitforce = thr->cgpu; + unsigned int wait; + + /* Pause each new thread a random time between 0-100ms + so the devices aren't making calls all at the same time. */ + wait = (rand() * MAX_START_DELAY_US)/RAND_MAX; + applog(LOG_DEBUG, "BFL%i: Delaying start by %dms", bitforce->device_id, wait / 1000); + usleep(wait); + + return true; +} + static struct api_data *bitforce_api_stats(struct cgpu_info *cgpu) { struct api_data *root = NULL; @@ -548,6 +562,7 @@ struct device_api bitforce_api = { .get_statline_before = get_bitforce_statline_before, .get_stats = bitforce_get_stats, .thread_prepare = bitforce_thread_prepare, + .thread_init = bitforce_thread_init, .scanhash = bitforce_scanhash, .thread_shutdown = bitforce_shutdown, .thread_enable = biforce_thread_enable
