ckolivas ac45260e 2012-07-02T16:12:35 Random style cleanups.
ckolivas 06ec47b3 2012-07-02T12:45:16 Must always unlock mutex after cond timedwait.
ckolivas df5d196f 2012-07-02T12:37:15 Must unlock mutex if pthread_cond_wait succeeds.
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 86c8bbe5 2012-06-29T17:19:28 Need to run Hashmeter all the time. and not just if logging/display is enabled
Paul Sheppard 75a651c1 2012-06-28T16:08:10 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.

Con Kolivas eddd02fe 2012-06-27T23:32:50 Put upper bounds to under 2 hours that work can be rolled into the future for bitcoind will deem it invalid beyond that.
Con Kolivas bcec5f51 2012-06-27T23:30:50 Revert "Check we don't exhaust the entire unsigned 32 bit ntime range when rolling time to cope with extremely high hashrates." This reverts commit 522f620c89b5f152f86a2916b0dca7b71b2a5005. Unrealistic. Limits are bitcoind related to 2 hours in the future.

ckolivas 21a23a45 2012-06-27T10:15:57 Work around pools that advertise very low expire= time inappropriately as this leads to many false positives for stale shares detected.
Paul Sheppard d3e2b62c 2012-06-26T14:45:48 Change sick/dead processing to use device pointer, not gpu array. Change BFL timing to adjust only when hashing complete (not error/idle etc.).

ckolivas b198423d 2012-06-26T16:01:06 Don't keep rolling work right up to the expire= cut off. Use 2/3 of the time between the scantime and the expiry as cutoff for reusing work.
ckolivas 6e80b63b 2012-06-26T15:43:03 Revert "Increase the getwork delay factored in to determine if work vs share is stale to avoid too tight timing." This reverts commit d8de1bbc5baa416148f50938cfde28a5261cb0e1. Wrong fix.

Con Kolivas 17ba2dca 2012-06-25T10:51:45 Logic fail on queueing multiple requests at once. Just queue one at a time.

Con Kolivas 63dd598e 2012-06-25T00:42:51 Queue multiple requests at once when levels are low.

Con Kolivas 32f52721 2012-06-25T00:03:37 Revert "With better bounds on the amount of work cloned, there is no need to age work and ageing it was picking off master work items that could be further rolled." This reverts commit 5d90c50fc08644c9b0c3fb7d508b2bc84e9a4163.
Con Kolivas 5d90c50f 2012-06-24T23:38:24 With better bounds on the amount of work cloned, there is no need to age work and ageing it was picking off master work items that could be further rolled.
Con Kolivas 47f66405 2012-06-24T23:10:02 Alternatively check staged work count for rolltime capable pools when deciding to queue requests.
Con Kolivas efa9569b 2012-06-24T22:59:56 Test we have enough work queued for pools with and without rolltime capability.
Con Kolivas 1bbc860a 2012-06-24T22:47:51 Don't count longpoll work as a staged extra work.
Con Kolivas ebaa615f 2012-06-24T22:16:04 Count extra cloned work in the total queued count.
Con Kolivas 74cd6548 2012-06-24T22:00:37 Use a static base measurement difference of how many items to clone since requests_staged may not climb while rolling.
Con Kolivas 7b57df11 2012-06-24T21:58:52 Allow 1/3 extra buffer of staged work when ageing it.
Con Kolivas 53269a97 2012-06-24T21:57:49 Revert "Simplify the total_queued count to those staged not cloned and remove the locking since it's no longer a critical value." This reverts commit 9f811c528f6eefbca5f16c92181783f756e3a68f.

Con Kolivas ded16838 2012-06-24T20:48:02 Add the getwork delay time instead of subtracting it when determining if a share is stale.
Con Kolivas b5757d12 2012-06-24T20:45:47 Don't count getwork delay when determining if shares are stale.
Con Kolivas 9f811c52 2012-06-24T20:38:40 Simplify the total_queued count to those staged not cloned and remove the locking since it's no longer a critical value. Clone only anticipated difference sicne there will be a lag from the value returned by requests_staged(). Keep 1/3 buffer of extra work items when ageing them.
Con Kolivas 411784a9 2012-06-24T19:53:31 As work is sorted by age, we can discard the oldest work at regular intervals to keep only 1 of the newest work items per mining thread.
Con Kolivas 359635a8 2012-06-24T18:44:09 Only roll enough work to have one staged work for each mining thread.

Con Kolivas a8ae1a43 2012-06-24T14:38:31 Rolltime should be used as the cutoff time for primary work as well as the rolled work, if present.
Con Kolivas c20a89d9 2012-06-24T14:20:29 Take into account average getwork delay as a marker of pool communications when considering work stale.
Con Kolivas f32ffb87 2012-06-24T13:20:17 Work out a rolling average getwork delay stored in pool_stats.
Con Kolivas 4e60a62a 2012-06-24T12:55:56 Getwork delay in stats should include retries for each getwork call.
ckolivas 6a45cbbd 2012-06-23T23:45:08 Merge branch 'master' of https://github.com/ckolivas/cgminer
ckolivas c5a21fab 2012-06-23T23:43:22 Extend nrolltime to support the expiry= parameter. Do this by turning the rolltime bool into an integer set to the expiry time. If the pool supports rolltime but not expiry= then set the expiry time to the standard scantime.

Luke Dashjr 1215da39 2012-06-18T05:51:09 modminer: Don't delay 2nd+ FPGAs during work restart Add primary_thread boolean to threads to identify a single one as the "primary" thread for shared-resource multithreading.
