Con Kolivas	ebaa2be1df	Update poclbm kernel for better performance on GCN and new SDKs with bitalign support when not BFI INT patching. Update phatk kernel to work properly for non BFI INT patched kernels, providing support for phatk to run on GCN and non-ATI cards.	13 years ago
Con Kolivas	3567b69e5e	Remove fragile source patching for bitalign, vectors et. al and simply pass it with the compiler options.	13 years ago
Con Kolivas	6d10ef2f6e	Bump version numbers of kernels to indicate slightly different versions.	13 years ago
Con Kolivas	bd79a61c43	Move poclbm to new branch optimisation as well.	13 years ago
Con Kolivas	cf54f9b850	Move to 256 sized buffers and don't risk overwrite by using only 127 mask.	13 years ago
Con Kolivas	0f782ba6bd	Update poclbm kernel to FF sized mask and only check that range.	13 years ago
Con Kolivas	95f878294f	The extra shift in the output actually appears detrimental in cgminer and there is a miniscule chance of missing the actual result if it ends up in the same spot as MAXBUFFERS.	13 years ago
Con Kolivas	a7707a26cb	Rename the poclbm file to ensure a new binary is built since.	13 years ago
Con Kolivas	b198badcf4	The poclbm kernel needs to be updated to work with the change to 4k sized output buffers.	13 years ago
Con Kolivas	13b43cfad1	Update copyright and authors.	13 years ago
Con Kolivas	2b6e841673	Use a buffer of up to 512 * 4 integers when retrieving work from the GPU. This allows each local thread id to have one slot to put any positive results into, thus making overlapping results far less likely. Thus races will be much rarer, allowing more threads. It should also pick up blocks close to each other more reliably and hopefully decrease the number of rejects and opencl errors. Do the search over the buffer entirely in a separate thread to allow the GPU to stay as busy as possible. Detach threads from themselves to prevent unlucky even where dereferencing occurs by freeing the data that stores the thread info.	13 years ago
Con Kolivas	2dbb39444d	Base was being set wrongly meaning we were repeating searches and the rate was actually lower than displayed :( Tweak Ma with new changes. Change default vectors to 2 since it's faster than 4 even when 4 is reported as preferred.	13 years ago
Con Kolivas	623b9b9fd8	Patch bitalign separately from bfi_int. Recover from failing to patch for bfi int.	13 years ago
Con Kolivas	8253f1414b	Use some line breaks in the kernel.	13 years ago
Con Kolivas	4257deafdb	Convert abcd... to an array.	13 years ago
Con Kolivas	75cf5ccda6	Replace Ws with an array.	13 years ago
ckolivas	19eea9067f	Implement code detecting max work size and optimal vector width. Use this to patch the kernel to suit the idea values for the card. Then use these values when invoking the kernel.	13 years ago
Con Kolivas	f54d2cc0ed	Make poclbm use 4 vectors and decrease worksize to keep pipelines fullish. Make it possible to have 0 CPU threads and update docs. Fix counter with no cpu threads.	13 years ago
ckolivas	b4d2733cfc	Convert to poclbm kernel.	13 years ago
