From: Chris Forbes Date: Sun, 16 Dec 2012 06:50:26 +0000 (+1300) Subject: i965: add support for multisample textures X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e62b6a10bcebae9fe6cb8fe81e95941ac06f13cd;p=mesa.git i965: add support for multisample textures V2: - Fix for state moving from texobj to image - Rebased onto Paul's logical/physical cleanup - Fixed missing quantization of sample count - Fold in IMS renderbuffer wrapper fixes from later in the series - Use correct physical slice offset for UMS/CMS surfaces on Gen7 Signed-off-by: Chris Forbes Reviewed-by: Paul Berry --- diff --git a/src/mesa/drivers/dri/i965/brw_tex_layout.c b/src/mesa/drivers/dri/i965/brw_tex_layout.c index 1428396c907..d28e5aff009 100644 --- a/src/mesa/drivers/dri/i965/brw_tex_layout.c +++ b/src/mesa/drivers/dri/i965/brw_tex_layout.c @@ -168,6 +168,7 @@ brw_miptree_layout(struct intel_context *intel, struct intel_mipmap_tree *mt) case GL_TEXTURE_2D_ARRAY: case GL_TEXTURE_1D_ARRAY: + case GL_TEXTURE_2D_MULTISAMPLE_ARRAY: brw_miptree_layout_texture_array(intel, mt); break; diff --git a/src/mesa/drivers/dri/i965/brw_wm_surface_state.c b/src/mesa/drivers/dri/i965/brw_wm_surface_state.c index 587ad053081..267d00b60ee 100644 --- a/src/mesa/drivers/dri/i965/brw_wm_surface_state.c +++ b/src/mesa/drivers/dri/i965/brw_wm_surface_state.c @@ -60,6 +60,8 @@ translate_tex_target(GLenum target) case GL_TEXTURE_2D: case GL_TEXTURE_2D_ARRAY_EXT: case GL_TEXTURE_EXTERNAL_OES: + case GL_TEXTURE_2D_MULTISAMPLE: + case GL_TEXTURE_2D_MULTISAMPLE_ARRAY: return BRW_SURFACE_2D; case GL_TEXTURE_3D: diff --git a/src/mesa/drivers/dri/intel/intel_fbo.c b/src/mesa/drivers/dri/intel/intel_fbo.c index 9a9bb9f3abc..7186978b4a0 100644 --- a/src/mesa/drivers/dri/intel/intel_fbo.c +++ b/src/mesa/drivers/dri/intel/intel_fbo.c @@ -499,15 +499,33 @@ intel_renderbuffer_update_wrapper(struct intel_context *intel, rb->Format = image->TexFormat; rb->InternalFormat = image->InternalFormat; rb->_BaseFormat = image->_BaseFormat; - rb->Width = mt->level[level].width; - rb->Height = mt->level[level].height; + rb->NumSamples = mt->num_samples; + + if (mt->msaa_layout != INTEL_MSAA_LAYOUT_NONE) { + assert(level == 0); + rb->Width = mt->logical_width0; + rb->Height = mt->logical_height0; + } + else { + rb->Width = mt->level[level].width; + rb->Height = mt->level[level].height; + } rb->Delete = intel_delete_renderbuffer; rb->AllocStorage = intel_nop_alloc_storage; intel_miptree_check_level_layer(mt, level, layer); irb->mt_level = level; - irb->mt_layer = layer; + + switch (mt->msaa_layout) { + case INTEL_MSAA_LAYOUT_UMS: + case INTEL_MSAA_LAYOUT_CMS: + irb->mt_layer = layer * mt->num_samples; + break; + + default: + irb->mt_layer = layer; + } intel_miptree_reference(&irb->mt, mt); diff --git a/src/mesa/drivers/dri/intel/intel_mipmap_tree.c b/src/mesa/drivers/dri/intel/intel_mipmap_tree.c index ee058a1029e..749508f8ae8 100644 --- a/src/mesa/drivers/dri/intel/intel_mipmap_tree.c +++ b/src/mesa/drivers/dri/intel/intel_mipmap_tree.c @@ -624,9 +624,27 @@ intel_miptree_match_image(struct intel_mipmap_tree *mt, * minification.
