From 151e7ac3cf045ed24c1990a42c040599311086c6 Mon Sep 17 00:00:00 2001 From: Neil Roberts Date: Mon, 9 Jun 2014 17:43:37 +0100 Subject: [PATCH] i965: Set the fast clear color value for texture surfaces When a multisampled texture is used for sampling the fast clear color value needs to be programmed into the surface state. This was being left as all zeroes so if the surface was cleared to a value other than black then it wouldn't work properly. This doesn't matter for single-sample textures because in that case the MCS buffer is resolved before it is used as a texture source. https://bugs.freedesktop.org/show_bug.cgi?id=79729 Reviewed-by: Chris Forbes Reviewed-by: Ian Romanick Cc: "10.1 10.2" (cherry picked from commit 765efeef883cdbb86e052acd887e0c3c0e39b732) --- src/mesa/drivers/dri/i965/gen7_wm_surface_state.c | 4 +++- src/mesa/drivers/dri/i965/gen8_surface_state.c | 4 +++- 2 files changed, 6 insertions(+), 2 deletions(-) diff --git a/src/mesa/drivers/dri/i965/gen7_wm_surface_state.c b/src/mesa/drivers/dri/i965/gen7_wm_surface_state.c index dad3b0c6f29..a25ec57e2ce 100644 --- a/src/mesa/drivers/dri/i965/gen7_wm_surface_state.c +++ b/src/mesa/drivers/dri/i965/gen7_wm_surface_state.c @@ -330,6 +330,8 @@ gen7_update_texture_surface(struct gl_context *ctx, /* mip count */ (intelObj->_MaxLevel - tObj->BaseLevel)); + surf[7] = mt->fast_clear_color_value; + if (brw->is_haswell) { /* Handling GL_ALPHA as a surface format override breaks 1.30+ style * texturing functions that return a float, as our code generation always @@ -344,7 +346,7 @@ gen7_update_texture_surface(struct gl_context *ctx, const bool need_scs_green_to_blue = for_gather && tex_format == BRW_SURFACEFORMAT_R32G32_FLOAT_LD; - surf[7] = + surf[7] |= SET_FIELD(brw_swizzle_to_scs(GET_SWZ(swizzle, 0), need_scs_green_to_blue), GEN7_SURFACE_SCS_R) | SET_FIELD(brw_swizzle_to_scs(GET_SWZ(swizzle, 1), need_scs_green_to_blue), GEN7_SURFACE_SCS_G) | SET_FIELD(brw_swizzle_to_scs(GET_SWZ(swizzle, 2), need_scs_green_to_blue), GEN7_SURFACE_SCS_B) | diff --git a/src/mesa/drivers/dri/i965/gen8_surface_state.c b/src/mesa/drivers/dri/i965/gen8_surface_state.c index efadb0da122..7df9f9abfa4 100644 --- a/src/mesa/drivers/dri/i965/gen8_surface_state.c +++ b/src/mesa/drivers/dri/i965/gen8_surface_state.c @@ -195,9 +195,11 @@ gen8_update_texture_surface(struct gl_context *ctx, (firstImage->_BaseFormat == GL_DEPTH_COMPONENT || firstImage->_BaseFormat == GL_DEPTH_STENCIL); + surf[7] = mt->fast_clear_color_value; + const int swizzle = unlikely(alpha_depth) ?
