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_screen.c | 13 ++++++++++++- 1 file changed, 12 insertions(+), 1 deletion(-) (limited to 'src/mesa/drivers/dri/intel/intel_screen.c') diff --git a/src/mesa/drivers/dri/intel/intel_screen.c b/src/mesa/drivers/dri/intel/intel_screen.c index 2728823142..6521b4ef31 100644 --- a/src/mesa/drivers/dri/intel/intel_screen.c +++ b/src/mesa/drivers/dri/intel/intel_screen.c @@ -49,6 +49,10 @@ #include "i915_drm.h" #include "i830_dri.h" +#define DRI_CONF_TEXTURE_TILING(def) \ + DRI_CONF_OPT_BEGIN(texture_tiling, bool, def) \ + DRI_CONF_DESC(en, "Enable texture tiling") \ + DRI_CONF_OPT_END \ PUBLIC const char __driConfigOptions[] = DRI_CONF_BEGIN @@ -64,6 +68,13 @@ PUBLIC const char __driConfigOptions[] = DRI_CONF_ENUM(1, "Enable reuse of all sizes of buffer objects") DRI_CONF_DESC_END DRI_CONF_OPT_END + +#ifdef I915 + DRI_CONF_TEXTURE_TILING(false) +#else + DRI_CONF_TEXTURE_TILING(true) +#endif + DRI_CONF_SECTION_END DRI_CONF_SECTION_QUALITY DRI_CONF_FORCE_S3TC_ENABLE(false) @@ -76,7 +87,7 @@ PUBLIC const char __driConfigOptions[] = DRI_CONF_SECTION_END DRI_CONF_END; -const GLuint __driNConfigOptions = 8; +const GLuint __driNConfigOptions = 9; #ifdef USE_NEW_INTERFACE static PFNGLXCREATECONTEXTMODES create_context_modes = NULL; -- cgit v1.2.3
