From 7216679c1998b49ff5b08e6b43f8d5779415bf54 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Thu, 9 Oct 2008 11:45:58 -0700 Subject: [PATCH] i965: Accelerate depth textures with border color. The fallback was introduced to fix bug #16697, but made the test it was fixing run excessively long. --- src/mesa/drivers/dri/i965/brw_fallback.c | 5 +---- .../drivers/dri/i965/brw_wm_sampler_state.c | 21 +++++++++++++++++-- 2 files changed, 20 insertions(+), 6 deletions(-) diff --git a/src/mesa/drivers/dri/i965/brw_fallback.c b/src/mesa/drivers/dri/i965/brw_fallback.c index 2f6b7febbde..4ea660a51a3 100644 --- a/src/mesa/drivers/dri/i965/brw_fallback.c +++ b/src/mesa/drivers/dri/i965/brw_fallback.c @@ -74,10 +74,7 @@ static GLboolean do_check_fallback(struct brw_context *brw) if (texUnit->_ReallyEnabled) { struct intel_texture_object *intelObj = intel_texture_object(texUnit->_Current); struct gl_texture_image *texImage = intelObj->base.Image[0][intelObj->firstLevel]; - if (texImage->Border || - ((texImage->_BaseFormat == GL_DEPTH_COMPONENT) && - ((texImage->TexObject->WrapS == GL_CLAMP_TO_BORDER) || - (texImage->TexObject->WrapT == GL_CLAMP_TO_BORDER)))) { + if (texImage->Border) { DBG("FALLBACK: texture border\n"); return GL_TRUE; } diff --git a/src/mesa/drivers/dri/i965/brw_wm_sampler_state.c b/src/mesa/drivers/dri/i965/brw_wm_sampler_state.c index 977b90ad43e..f12ef47a7d7 100644 --- a/src/mesa/drivers/dri/i965/brw_wm_sampler_state.c +++ b/src/mesa/drivers/dri/i965/brw_wm_sampler_state.c @@ -229,6 +229,9 @@ brw_wm_sampler_populate_key(struct brw_context *brw, struct wm_sampler_entry *entry = &key->sampler[unit]; struct gl_texture_unit *texUnit = &brw->attribs.Texture->Unit[unit]; struct gl_texture_object *texObj = texUnit->_Current; + struct intel_texture_object *intelObj = intel_texture_object(texObj); + struct gl_texture_image *firstImage = + texObj->Image[0][intelObj->firstLevel]; entry->wrap_r = texObj->WrapR; entry->wrap_s = texObj->WrapS; @@ -244,8 +247,22 @@ brw_wm_sampler_populate_key(struct brw_context *brw, entry->comparefunc = texObj->CompareFunc; dri_bo_unreference(brw->wm.sdc_bo[unit]); - brw->wm.sdc_bo[unit] = upload_default_color(brw, texObj->BorderColor); - + if (firstImage->_BaseFormat == GL_DEPTH_COMPONENT) { + float bordercolor[4] = { + texObj->BorderColor[0], + texObj->BorderColor[0], + texObj->BorderColor[0], + texObj->BorderColor[0] + }; + /* GL specs that border color for depth textures is taken from the + * R channel, while the hardware uses A.
