- This is just not part of spec, there is no enforcement for multiple of block size for width or height of s3tc compressed images.
- This restriction does indeed exist for ASTC and ETC but we're not using those formats.
Drop AVX2 path for now, since it usually operates on small data.
Rely on automatic SSE vectorization on recent compilers.
Side refactoring on JIT.h to workaround weird conflict issue.
- Calculates precise Z value as requested by the game
- Works properly if the underlying Z format matches the PS3 1:1 but may cause minor problems otherwise
Optimize CPU capability tests for arch-tuned builds.
Separate streaming and non-streaming utilities.
Rewritten copy_data_swap_u32(_cmp) with AVX2 path.
- Replace old format-based detection with proper aspect test.
Explicit image aspect has been available for a long time, but older
code was not updated.
- Specifically fixes a corner case where double transforms are required.
Technically this can be made more readable using transformation matrices:
* M1 = transform_virtual_to_physical()
* M2 = transform_image_to_virtual()
* M3 = M1 * M2
* Result = Input * M3
But we don't use a CPU-side matrix library and it is not reasonable to do this on the GPU.
- Just use RGB565 for all blit targets. Avoids really dumb transforms done by GPU hw.
- When X16 is used, all the channels get written to R channel alone. CmdBlit does perform format conversion!
- gl: Force image copy when blit is requested with compatible targets. Avoids format conversion issues.
- Treat the draw commands as being consumed on-the-fly with ATTR0 as provoking attribute
- Analysing streams sent to RSX and the results implies they are consumed fully inline.
This only makes sense if a provoking attribute is present. The 'static' register is truly the immediate register for the draw.
- Older games can load all textures before a draw sequence and then swap shaders for different draws.
- Optimizations in texture state streaming make it so that only referenced data is carried forward.
