Con Kolivas 5d23d70f 2012-02-22T14:14:26 As all kernels will be new versions it's an opportunity to change the .bin format and make it simpler. Specifying bitalign is redundant and long can be l.

Con Kolivas 728e3d43 2012-02-16T00:43:05 Revert "Automatically choose phatk kernel for bitalign non-gcn ATI cards, and then only select poclbm if SDK2.6 is detected." This reverts commit e7fdadfc8fc388f68772d5a4c2740da60287c889. Broke kernel loading.

Con Kolivas 2c33f122 2012-02-13T08:34:44 Whitelist ATI SDK 2.6 to use the poclbm kernel by default.
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.
Con Kolivas 56907db2 2012-02-12T18:21:30 Fix harmless warnings with -Wsign-compare to allow cgminer to build with -W.
Con Kolivas 405a2120 2012-02-11T20:11:18 Remove unnecessary check for opt_debug on every invocation of applog at LOG_DEBUG and place the check in applog().

Con Kolivas 55bd031d 2012-02-11T16:38:55 Variable unused after this so remove setting it.
Con Kolivas 1c1b8bec 2012-02-11T15:58:07 BFI INT patching is not necessarily true on binary loading of files and not true on ATI SDK2.6+. Report bitalign instead.

ckolivas 59d3d011 2012-02-10T14:33:40 Implement diablo kernel support and try to make it work.
ckolivas 95a989da 2012-02-10T13:18:16 Conflicting entries of cl_kernel may have been causing problems, and automatically chosen kernel type was not being passed on. Rename the enum to cl_kernels and store the chosen kernel in each clState.

ckolivas 5d5584f8 2012-01-29T16:31:03 Explicitly check for nvidia in opencl platform strings as well.
Con Kolivas a3d90f84 2012-01-29T11:01:17 Default to poclbm kernel on Tahiti (7970) since phatk does not work, even though performance is sub-standard so that at least it will mine successfully by default.
Con Kolivas 31f6e8c7 2012-01-28T17:06:28 Unset prog_built after it is patched because it needs rebuilding.
Con Kolivas 1e503549 2012-01-28T16:29:19 Retain cl program after every possible place we might build the program.
Con Kolivas 25caca90 2012-01-28T16:26:53 Revert "Don't explicitly retain the cl program as it is of no benefit to do so and may lead to problems when trying to release the program." This reverts commit 32910463a3124265b56aca48a6c0fbb107ccfb70. Turns out this does help.
Con Kolivas 32910463 2012-01-26T20:53:35 Don't explicitly retain the cl program as it is of no benefit to do so and may lead to problems when trying to release the program.
Con Kolivas d18d5564 2012-01-26T20:39:35 Do not attempt to build the program that becomes the kernel twice. This could have been leading to failures on initialising cl.
Con Kolivas c87460b3 2012-01-26T19:42:57 Typo.
Con Kolivas 2ecabd85 2012-01-26T19:38:15 Some opencl compilers have issues with no spaces after -D in the compiler options.
Con Kolivas 77e9b1c2 2012-01-26T13:06:39 Use calloced stack memory for CompilerOptions to ensure sprintf writes to the beginning of the char.
Con Kolivas d7aac254 2012-01-26T11:44:42 Whitelist 79x0 cards to prefer no vectors as they perform better without.
Con Kolivas 3d4cfce8 2012-01-24T20:23:44 Instead of using the BFI_INT patching hack on any device reporting cl_amd_media_ops, create a whitelist of devices that need it. This should enable GCN architectures (ATI 79xx cards) to work properly.
Con Kolivas 6442c1ab 2012-01-22T20:36:57 Style police.
Con Kolivas 0719d407 2012-01-22T17:09:06 Clean up on failure to load a binary kernel.
Con Kolivas fb0c580b 2011-10-15T13:29:44 Go to kernel build should we fail to clCreateProgramWithBinary instead of failing on that device. Should fix the windows problems with devices not initialising.
Con Kolivas 2053de6d 2011-09-06T10:11:34 Add the directory name from the arguments cgminer was called from as well to allow it running from a relative pathname.
