From: Chad Versace Date: Fri, 28 Aug 2015 14:44:32 +0000 (-0700) Subject: vk: Fix format of anv_depth_stencil_view X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b2ee317e24d9d236d0050b2a6188df379e913c45;p=mesa.git vk: Fix format of anv_depth_stencil_view The format of the view itself and of the view's image may differ. Moreover, if the view's format has no depth aspect but the image's format does, we must not program the depth buffer. Ditto for stencil. --- diff --git a/src/vulkan/anv_image.c b/src/vulkan/anv_image.c index 198f4a40212..6ab541e5bce 100644 --- a/src/vulkan/anv_image.c +++ b/src/vulkan/anv_image.c @@ -475,14 +475,28 @@ anv_depth_stencil_view_init(struct anv_depth_stencil_view *view, view->bo = image->bo; - view->depth_stride = image->depth_surface.stride; - view->depth_offset = image->offset + image->depth_surface.offset; - view->depth_format = image->format->depth_format; - view->depth_qpitch = 0; /* FINISHME: QPitch */ - - view->stencil_stride = image->stencil_surface.stride; - view->stencil_offset = image->offset + image->stencil_surface.offset; - view->stencil_qpitch = 0; /* FINISHME: QPitch */ + view->format = anv_format_for_vk_format(pCreateInfo->format); + assert(anv_format_is_depth_or_stencil(view->format)); + + if (view->format->depth_format) { + view->depth_stride = image->depth_surface.stride; + view->depth_offset = image->offset + image->depth_surface.offset; + view->depth_qpitch = 0; /* FINISHME: QPitch */ + } else { + view->depth_stride = 0; + view->depth_offset = 0; + view->depth_qpitch = 0; + } + + if (view->format->has_stencil) { + view->stencil_stride = image->stencil_surface.stride; + view->stencil_offset = image->offset + image->stencil_surface.offset; + view->stencil_qpitch = 0; /* FINISHME: QPitch */ + } else { + view->stencil_stride = 0; + view->stencil_offset = 0; + view->stencil_qpitch = 0; + } } struct anv_surface * diff --git a/src/vulkan/anv_private.h b/src/vulkan/anv_private.h index 2d037b4cbb3..594b4fedc6c 100644 --- a/src/vulkan/anv_private.h +++ b/src/vulkan/anv_private.h @@ -1119,6 +1119,7 @@ struct anv_color_attachment_view { struct anv_depth_stencil_view { struct anv_attachment_view base; + const struct anv_format *format; /**< VkAttachmentViewCreateInfo::format */ struct anv_bo *bo; diff --git a/src/vulkan/gen7_cmd_buffer.c b/src/vulkan/gen7_cmd_buffer.c index d9644e2a06a..1028b6dae22 100644 --- a/src/vulkan/gen7_cmd_buffer.c +++ b/src/vulkan/gen7_cmd_buffer.c @@ -543,14 +543,18 @@ gen7_cmd_buffer_begin_subpass(struct anv_cmd_buffer *cmd_buffer, view = (const struct anv_depth_stencil_view *)aview; } - if (view) { + const bool has_depth = view && view->format->depth_format; + const bool has_stencil = view && view->format->has_stencil; + + /* Emit 3DSTATE_DEPTH_BUFFER */ + if (has_depth) { anv_batch_emit(&cmd_buffer->batch, GEN7_3DSTATE_DEPTH_BUFFER, .SurfaceType = SURFTYPE_2D, - .DepthWriteEnable = view->depth_stride > 0, - .StencilWriteEnable = view->stencil_stride > 0, + .DepthWriteEnable = view->format->depth_format, + .StencilWriteEnable = has_stencil, .HierarchicalDepthBufferEnable = false, - .SurfaceFormat = view->depth_format, - .SurfacePitch = view->depth_stride > 0 ? view->depth_stride - 1 : 0, + .SurfaceFormat = view->format->depth_format, + .SurfacePitch = view->depth_stride - 1, .SurfaceBaseAddress = { view->bo, view->depth_offset }, .Height = fb->height - 1, .Width = fb->width - 1, @@ -559,11 +563,6 @@ gen7_cmd_buffer_begin_subpass(struct anv_cmd_buffer *cmd_buffer, .MinimumArrayElement = 0, .DepthBufferObjectControlState = GEN7_MOCS, .RenderTargetViewExtent = 1 - 1); - - anv_batch_emit(&cmd_buffer->batch, GEN7_3DSTATE_STENCIL_BUFFER, - .StencilBufferObjectControlState = GEN7_MOCS, - .SurfacePitch = view->stencil_stride > 0 ? view->stencil_stride - 1 : 0, - .SurfaceBaseAddress = { view->bo, view->stencil_offset }); } else { /* Even when no depth buffer is present, the hardware requires that * 3DSTATE_DEPTH_BUFFER be programmed correctly.
