Mesa demos src/tests/streaming_rect on Kaveri (radeonsi):
Unpatched: 42 frames in 1.023 seconds = 41.056 FPS
Patched: 615 frames in 1.000 seconds = 615.000 FPS
For comparison, with Fredrik Höglund's patches for PBO unpack
acceleration, I get 856 frames in 1.000 seconds = 856.000 FPS
BTW, Fredrik, what's the status of those patches? I get one piglit
regression with radeonsi (driver assertion failure in
spec/ARB_pixel_buffer_object/texsubimage pbo), other than that they seem
to work fine.
