From 7ad692d8e2bf619f5855552e3d56aafa9f5f21af Mon Sep 17 00:00:00 2001 From: Iago Toral Quiroga Date: Wed, 22 Feb 2017 11:33:13 +0100 Subject: [PATCH] anv: do not subtract the base layer to compute depth in 3DSTATE_DEPTH_BUFFER According to the PRM description of the Depth field: "This field specifies the total number of levels for a volume texture or the number of array elements allowed to be accessed starting at the Minimum Array Element for arrayed surfaces" However, ISL defines array_len as the length of the range [base_array_layer, base_array_layer + array_len], so it already represents a value relative to the base array layer like the hardware expects. v2: Depth is defined as a U11-1 field, so subtract 1 from the actual value (Jason) This fixes a number of new CTS tests that would crash otherwise: dEQP-VK.pipeline.render_to_image.* Reviewed-by: Jason Ekstrand --- src/intel/vulkan/genX_cmd_buffer.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/src/intel/vulkan/genX_cmd_buffer.c b/src/intel/vulkan/genX_cmd_buffer.c index e3f84e32dcc..2b070355d26 100644 --- a/src/intel/vulkan/genX_cmd_buffer.c +++ b/src/intel/vulkan/genX_cmd_buffer.c @@ -2268,8 +2268,7 @@ cmd_buffer_emit_depth_stencil(struct anv_cmd_buffer *cmd_buffer) assert(image->depth_surface.isl.dim != ISL_SURF_DIM_3D); db.Depth = - db.RenderTargetViewExtent = - iview->isl.array_len - iview->isl.base_array_layer - 1; + db.RenderTargetViewExtent = iview->isl.array_len - 1; #if GEN_GEN >= 8 db.SurfaceQPitch = -- 2.30.2
