217be6ed98 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. 2012-11-25 00:37:46 +11:00

2d35ac2567 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.

4fbc570fa4 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. 2012-10-11 20:30:47 +11:00

618999026f 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. 2012-09-21 16:10:34 +10:00

e5ed708493 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. 2012-08-20 16:02:32 +10:00
Con Kolivas
8745ba1e6d 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.
