dolphin/Data/User/OpenCL/TextureDecoder.cl, branch 3.0

Fix TextureDecoder.cl to work on both NVidia and ATI video cards.

2010-12-19T14:59:57+00:00

To do so I had to re-add the casting bloat removed in revision 6102.  Also, for some odd reason the NVidia OpenCL drivers don't like 8 bit rotations, but are okay with 2, 4 bit rotations.  These are apparently bugs in the NVidia drivers that are hopefully fixed in future versions.
Also, on linux make sure the TextureDecoder.cl file is copied from the shared data directory to the users directory.

Remove unnecessary casting bloat. Since AMD Stream 2.2 this is no longer a requirement.

Stream 2.2 is minimum requirement for OpenCL 1.1 and binary kernels as well (I hope to implement these soon).Remove unnecessary casting bloat. Since AMD Stream 2.2 this is no longer a requirement.

Sidenote: Stream 2.2/Catalyst 10.7b is minimum requirement for OpenCL 1.1 and binary kernels as well. I hope to implement these soon.

Small update to fix some cmpr alpha issues with games that use linear filtering. Apparently the colour values matter even though alpha = 0.

Also, remove redundant ANDs.

Changes:

2010-06-24T04:06:03+00:00

 - RGBA8 (DX9/OGL): 10x speed up on Radeon 5450, 2x speed up on other cards due to swizzle registers.
 - RGB565: 2-3x speed up on all hardware
 - Removed OpenCL compiler warnings (eg. redefine).
OpenCL is now optimally complete for DX9/OGL. The code is very fast on all supported hardware. No more updates are needed unless the spec changes or drivers improve. When I started, the OpenCL code was as slow or slower than CPU. Now, using the lowest end radeon that supports the code: a Radeon 45xx mobility, I experience a substantial 2-10x speedup over CPU. The benefits are more pronounced with modern hardware. A Radeon 5870 runs this code 20x faster than a 4550. Even ignoring speedups, the code benefits users by not using CPU for intermittent texture loads (unless GPU is your bottleneck). Instead, the CPU is able to do more important tasks.

New OpenCL update for DX11

2010-06-22T06:09:21+00:00

Changes:
 - IA4: 2x Speed up for all hardware and ATI glitch fixed (blocky text)
 - IA8: 2x Speed up for all hardware
 - New DX11 OCL Textures: I4, I8, IA4, IA8

git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@5766 8ced0084-cf51-0410-be5f-012b33b47a6e

Added OpenCL texture decoding to RGBA usable by DX11 for formats RGB565, RGBA8, RGB5A3 and CMPR

Fix color precision problems when decoding CMPR and RGB5A3 textures with OpenCL

2010-06-21T22:21:06+00:00

git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@5763 8ced0084-cf51-0410-be5f-012b33b47a6e

A new update for OpenCL.h.

2010-06-21T13:09:25+00:00

Changes:
 - Strict casting as required by NVidia. Now NVidia cards should work.
 - Fixed Alpha CMPR bug.

Please tell me if you find any bugs. Current known bug is the 'Press' texture in Paper Mario that is meant to flash rainbow colours appears black. Other than that, everything should work on every videocard.

Hi! This is my first commit so be nice :)

2010-06-20T16:43:21+00:00

New OpenCL updates:
 - OpenCL bug with ATI SDK (GPU or CPU) fixed.
 - IA4 texture loop unrolled. 12x speed up on 4xxx series.
 - Completed rewriting RGB5A3 texture decode. 20% faster.
 - Redundant code removed from CMPR and RGB5A3 (Alpha, shift).
 - Made use of optimised OpenCL functions (upsample, bitselect).
 - Cleaner code.

Tested and working with DX9 plugin. DX11 plugin will NOT work due to a recent commit affecting VideoCommon. You can use this file with an older DX11 plugin (~r5730), however.

Some more OCL changes : Gives 10x speedup for RGB5A3 on pre-DX11 hardware. Minor speedup for CMPR. (code by xsacha)

2010-06-20T05:02:26+00:00

plus a segfault fix for issue 2779
