Comment 40 for bug 1432949

That piglit sanity is failing with the patch may confirm my suspicion that something doesn't add up yet I'm afraid: Since the kernel driver and xf86-video-ati EXA code are using the same hardware formats for display/rendering with BE & LE, I was wondering how the patch could result in both display and glReadPixels working correctly for winsys buffers. Looks like indeed only display works correctly, which indicates that the GPU is effectively writing/reading PIPE_FORMAT_x8R8G8B8_* pixels like PIPE_FORMAT_B8G8R8x8_* (which is what the kernel driver and EXA code are using).
