[Mesa-dev] [PATCH] i965: Prefer Meta over the BLT for BlitFramebuffer.

2015-02-17 Thread Kenneth Graunke
There's some debate about whether we should use Meta or BLORP, but either should run circles around the BLT engine. In particular, this means that Gen8+ will use the 3D engine for blits, like we do on Gen6-7. Improves performance in "copypixrate -blit -back" (from Mesa demos) by 232.037% +/- 3.15

[Mesa-dev] [PATCH] i965: Prefer Meta over the BLT for BlitFramebuffer.

2015-01-15 Thread Kenneth Graunke
There's some debate about whether we should use Meta or BLORP, but either should run circles around the BLT engine. Improves performance in "copypixrate -blit -back" (from Mesa demos) by 232.037% +/- 3.15795% (n=10) on Broadwell GT3e. Signed-off-by: Kenneth Graunke --- src/mesa/drivers/dri/i965
