217be6ed	2012-11-25T00:37:46	Do away with the flaky free_work api in the driver code which would often lose the work data in opencl and simply flush it before exiting the opencl scanhash.
ce7801be	2012-11-24T12:49:20	Copy the work on opencl_free_work
2d35ac25	2012-11-24T10:47:20	Track all dynamically allocated memory within the work struct by copying work structs in a common place, creating freshly allocated heap ram for all arrays within the copied struct. Clear all work structs from the same place to ensure memory does not leak from arrays within the struct. Convert the gbt coinbase and stratum strings within the work struct to heap ram. This will allow arbitrary lengths without an upper limit for the strings, preventing the overflows that happen with GBT.
cce75083	2012-11-18T22:24:40	opencl: Use new dev_error function for REASON_DEV_NOSTART
101394ab	2012-10-18T00:57:03	Time for dynamic is in microseconds, not ms.
7450b25e	2012-10-14T12:07:27	Dramatically simplify the dynamic intensity calculation by oversampling many runs through the opencl kernel till we're likely well within the timer resolution on windows.
1c22c0e8	2012-10-14T08:37:54	In opencl_free_work, make sure to still flush results in dynamic mode.
55396f53	2012-10-12T11:35:20	Fix 4 * 0 being 0 that would break dynamic intensity mode.
4fbc570f	2012-10-11T20:30:47	Reinstate the history on dynamic intensity mode to damp fluctuations in intensity but use an upper limit on how much the value can increase at any time to cope with rare overflows.
61899902	2012-09-21T16:10:34	As we average gpu time over 5 work intervals for dynamic GPU intensity, there is no need to maintain a rolling average and it avoids the potential long term corruption of a single overflow value.
f1c6ae22	2012-08-31T09:13:19	Adjust opencl intensity when adjusting thread count to prevent it getting pegged at a value below the minimum threads possible.

e5ed7084	2012-08-20T14:52:06	Do the dynamic timing in opencl code over a single pass through scanhash to make sure we're only getting opencl times contributing to the measured intervals.
8745ba1e	2012-08-15T09:38:45	Windows' timer resolution is limited to 15ms accuracy. This was breaking dynamic intensity since it tries to measure below this. Since we are repeatedly sampling similar timeframes, we can average the gpu_us result over 5 different values to get very fine precision.
fc44b6d7	2012-08-05T15:32:44	Use different variables for command line specified lookup gap and thread concurrency to differentiate user defined versus auto chosen values.
