From 93f701bc3619864ac6f067d37212e96545a57e16 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 26 Jun 2008 13:45:31 -0700 Subject: intel: Replace sprinkled intel_batchbuffer_flush with MI_FLUSH or nothing. Most of these were to ensure that caches got synchronized between 2d (or meta) rendering and later use of the target as a source, such as for texture miptree setup. Those are replaced with intel_batchbuffer_emit_mi_flush(), which just drops an MI_FLUSH. Most of the remainder were to ensure that REFERENCES_CLIPRECTS batchbuffers got flushed before the lock was dropped. Those are now replaced by automatically flushing those when dropping the lock. --- src/mesa/drivers/dri/i915/intel_pixel_read.c | 2 - src/mesa/drivers/dri/i965/brw_defines.h | 63 ----------------------- src/mesa/drivers/dri/intel/intel_batchbuffer.h | 8 +++ src/mesa/drivers/dri/intel/intel_blit.c | 25 ++++----- src/mesa/drivers/dri/intel/intel_buffer_objects.c | 1 + src/mesa/drivers/dri/intel/intel_context.c | 3 +- src/mesa/drivers/dri/intel/intel_pixel_bitmap.c | 5 +- src/mesa/drivers/dri/intel/intel_pixel_copy.c | 6 +-- src/mesa/drivers/dri/intel/intel_pixel_draw.c | 3 +- src/mesa/drivers/dri/intel/intel_regions.c | 4 -- src/mesa/drivers/dri/intel/intel_tex_copy.c | 2 - src/mesa/drivers/dri/intel/intel_tex_image.c | 2 - src/mesa/drivers/dri/intel/intel_tex_validate.c | 14 ----- 13 files changed, 26 insertions(+), 112 deletions(-) (limited to 'src/mesa') diff --git a/src/mesa/drivers/dri/i915/intel_pixel_read.c b/src/mesa/drivers/dri/i915/intel_pixel_read.c index 0b95421a25..72e1f9ed28 100644 --- a/src/mesa/drivers/dri/i915/intel_pixel_read.c +++ b/src/mesa/drivers/dri/i915/intel_pixel_read.c @@ -272,8 +272,6 @@ do_blit_readpixels(GLcontext * ctx, rect.x2 - rect.x1, rect.y2 - rect.y1, GL_COPY);
