From 339d42b4e684343c743ea819337c057c0046323f Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Thu, 4 Feb 2010 10:45:13 -0500 Subject: [PATCH] r600: reduce number of cache flushes We don't need to flush so often. Next step would be to move the flushing to the drm and only flush after each command buffer rather than each draw. --- src/mesa/drivers/dri/r600/r600_blit.c | 1 + src/mesa/drivers/dri/r600/r700_render.c | 5 ++--- 2 files changed, 3 insertions(+), 3 deletions(-) diff --git a/src/mesa/drivers/dri/r600/r600_blit.c b/src/mesa/drivers/dri/r600/r600_blit.c index d7cd59ade62..4bb77a398f9 100644 --- a/src/mesa/drivers/dri/r600/r600_blit.c +++ b/src/mesa/drivers/dri/r600/r600_blit.c @@ -1652,6 +1652,7 @@ unsigned r600_blit(GLcontext *ctx, CB_ACTION_ENA_bit | (1 << (id + 6))); /* 5 */ + /* XXX drm should handle this in fence submit */ r700WaitForIdleClean(context); radeonFlush(ctx); diff --git a/src/mesa/drivers/dri/r600/r700_render.c b/src/mesa/drivers/dri/r600/r700_render.c index 96c12ce544f..8f14af7472c 100644 --- a/src/mesa/drivers/dri/r600/r700_render.c +++ b/src/mesa/drivers/dri/r600/r700_render.c @@ -115,8 +115,6 @@ void r700Start3D(context_t *context) END_BATCH(); COMMIT_BATCH(); - - r700WaitForIdleClean(context); } GLboolean r700SyncSurf(context_t *context, @@ -421,7 +419,7 @@ static void r700RunRenderPrimitiveImmediate(GLcontext * ctx, int start, int end, } /* start 3d, idle, cb/db flush */ -#define PRE_EMIT_STATE_BUFSZ 10 + 5 + 18 +#define PRE_EMIT_STATE_BUFSZ 5 + 5 + 18 static GLuint r700PredictRenderSize(GLcontext* ctx, const struct _mesa_prim *prim, @@ -934,6 +932,7 @@ static GLboolean r700TryDrawPrims(GLcontext *ctx, radeon_debug_remove_indent(); /* Flush render op cached for last several quads. */ + /* XXX drm should handle this in fence submit */ r700WaitForIdleClean(context); rrb = radeon_get_colorbuffer(&context->radeon); -- 2.30.2
