I think the format conversion functions should look like:
#ifdef BIG_ENDIAN
case PIPE_FORMAT_A8B8G8R8_UNORM:
return hw_format_for_R8G8B8A8_UNORM;
...
#else
case PIPE_FORMAT_R8G8B8A8_UNORM:
return hw_format_for_R8G8B8A8_UNORM;
#endif
which can be simplified to:
case PIPE_FORMAT_RGBA8888_UNORM:
return hw_format_for_R8G8B8A8_UNORM;
So that the GPU can see the same formats, but they are different for the CPU.
What do you think?
