Con Kolivas 132ee4c9 2013-03-21T14:56:07 Do not scan other gpu platforms if one is specified.

Con Kolivas d0f18e83 2013-03-15T22:00:52 Do not round up the bufsize to the maximum allocable with scrypt.
Con Kolivas 3c3fbdce 2013-03-15T21:48:48 Remove the rounding-up of the scrypt padbuffer which was not effectual and counter-productive on devices with lots of ram, limiting thread concurrencies and intensities.
Con Kolivas 1c6d8a36 2013-03-15T19:43:38 bufsize is an unsigned integer, make it so for debug.
Con Kolivas 767d6df1 2013-03-09T16:35:06 Whitelist AMD APP SDK 2.8 for diablo kernel.
Con Kolivas 87b62bde 2013-03-09T16:19:00 Cope with the highest opencl platform not having usable devices.
Con Kolivas 266d3127 2013-02-10T15:07:49 Make the numbuf larger to accept larger scrypt parameters.
Con Kolivas 69494c12 2012-12-10T15:38:21 BeaverCreek doesn't like BFI INT patching.
Con Kolivas 25c39c96 2012-10-15T12:31:57 Ease the checking on allocation of padbuffer8 in the hope it works partially anyway on an apparently failed call.
Con Kolivas cc3b693c 2012-10-07T12:25:19 Minor warning fixes.
Con Kolivas 40b747ba 2012-10-07T10:00:02 Put scrypt warning on separate line to avoid 0 being shown on windows as bufsize.
Con Kolivas d91af893 2012-08-28T18:08:39 Use correct sdk version detection for SDK 2.7
Con Kolivas 69983b77 2012-08-28T17:19:38 Revert "Pick worksize 256 with Cypress if none is specified." This reverts commit 482322a4b7add8458bee946ffb247a9a587fc25f. Worksize 256 was only helpful on cypress with ultra-low memory speeds with old SDKs and the new kernels require higher memory clocks, having the opposite net effect.
Con Kolivas 4fbe5bed 2012-08-23T23:25:32 OpenCL 1.0 does not have native atomic_add and extremely slow support with atom_add so detect opencl1.0 and use a non-atomic workaround.

Con Kolivas da1b996a 2012-07-26T16:10:21 Simplify repeated use of gpus[gpu]. in ocl.c
Con Kolivas ea10b08d 2012-07-25T22:02:14 Find the nearest power of 2 maximum alloc size for the scrypt buffer that can successfully be allocated and is large enough to accomodate the thread concurrency chosen, thus mapping it to an intensity.
Con Kolivas 9a6c082a 2012-07-24T20:27:37 Make the thread concurrency and lookup gap options hidden on the command line and autotune parameters with a newly parsed --shaders option.
Con Kolivas 3a0d60cf 2012-07-23T21:30:30 Always create the largest possible padbuffer for scrypt kernels even if not needed for thread_concurrency, giving us some headroom for intensity levels.
Con Kolivas d8f81c18 2012-07-23T17:51:57 Use the detected maximum allocable memory on a GPU to determine the optimal scrypt settings when lookup_gap and thread_concurrency parameters are not given.
Con Kolivas 89eb1fa3 2012-07-23T17:41:31 Check the maximum allocable memory size per opencl device.

Con Kolivas fb99c8d5 2012-02-12T21:38:45 The longstanding generation of a zero sized binary appears to be due to the OpenCL library putting the binary in a RANDOM SLOT amongst 4 possible binary locations. Iterate over each of them after building from source till the real binary is found and use that.
