From 1ba96651e12b3c74fb9c8f5a61b183ef36a27b1e Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 3 Jun 2009 16:40:20 +0000 Subject: intel: Add support for tiled textures. This is about a 30% performance win in OA with high settings on my GM45, and experiments with 915GM indicate that it'll be around a 20% win there. Currently, 915-class hardware is seriously hurt by the fact that we use fence regs to control the tiling even for 3D instructions that could live without them, so we spend a bunch of time waiting on previous rendering in order to pull fences off. Thus, the texture_tiling driconf option defaults off there for now. --- src/mesa/drivers/dri/intel/intel_context.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'src/mesa/drivers/dri/intel/intel_context.h') diff --git a/src/mesa/drivers/dri/intel/intel_context.h b/src/mesa/drivers/dri/intel/intel_context.h index 810f3e62d9..4e45f1a91f 100644 --- a/src/mesa/drivers/dri/intel/intel_context.h +++ b/src/mesa/drivers/dri/intel/intel_context.h @@ -305,6 +305,8 @@ struct intel_context */ GLboolean is_front_buffer_rendering; + GLboolean use_texture_tiling; + drm_clip_rect_t fboRect; /**< cliprect for FBO rendering */ int perf_boxes; -- cgit v1.2.3
