SDMA is much faster for tiled->linear blits from VRAM to GTT. I have Bonaire in my second PCIe slot. $ glxinfo | grep OpenGL.renderer OpenGL renderer string: Gallium 0.4 on AMD TONGA ... $ DRI_PRIME=1 glxinfo | grep OpenGL.renderer OpenGL renderer string: Gallium 0.4 on AMD BONAIRE ... Without SDMA: $ DRI_PRIME=1 glxgears 8796 frames in 5.0 seconds = 1759.074 FPS 8899 frames in 5.0 seconds = 1779.672 FPS With SDMA: $ DRI_PRIME=1 glxgears 12765 frames in 5.0 seconds = 2552.788 FPS 12888 frames in 5.0 seconds = 2577.495 FPS The 1st GPU is irrelevant. The improvement should be much lower at 60 fps, but definitely measurable. SI will get this once we add SDMA blit support for it. Reviewed-by: Bas Nieuwenhuizen <bas@basnieuwenhuizen.nl> |
