From b9e2cde6006b557a3a23a82384899f4d5a5ac7b8 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Tue, 15 Feb 2011 05:43:44 +0100 Subject: [PATCH] r300g: offload the CS ioctl to another thread This is a multi-threading optimization which hides the kernel overhead behind a thread. It improves performance in CPU-limited apps by 2-15%. Of course you must have at least 2 cores for it to make any difference. It can be disabled with: export RADEON_THREAD=0 --- src/gallium/drivers/r300/r300_flush.c | 4 + src/gallium/drivers/r300/r300_winsys.h | 11 +- src/gallium/winsys/radeon/drm/radeon_drm_bo.c | 8 + src/gallium/winsys/radeon/drm/radeon_drm_bo.h | 4 + src/gallium/winsys/radeon/drm/radeon_drm_cs.c | 266 +++++++++++++++++--------- src/gallium/winsys/radeon/drm/radeon_drm_cs.h | 53 +++-- 6 files changed, 233 insertions(+), 113 deletions(-) diff --git a/src/gallium/drivers/r300/r300_flush.c b/src/gallium/drivers/r300/r300_flush.c index bfc15ce..c4bb332 100644 --- a/src/gallium/drivers/r300/r300_flush.c +++ b/src/gallium/drivers/r300/r300_flush.c @@ -94,6 +94,10 @@ static void r300_flush(struct pipe_context* pipe, r300->rws->cs_flush(r300->cs);
