From 29e5d5db5149f721e6c15a9aee6f8135a98ba5c8 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Tue, 13 Aug 2013 13:54:37 -0700 Subject: [PATCH] i965: Also emit HIER_DEPTH and STENCIL packets when disabling depth. From the documentation: "[DevIVB] 3DSTATE_DEPTH_BUFFER must always be programmed along with the other Depth/Stencil state commands(i.e. 3DSTATE_CLEAR_PARAMS, 3DSTATE_STENCIL_BUFFER, or 3DSTATE_HIER_DEPTH_BUFFER)." We normally do this, but BLORP was failing to do so in the case where it disables depth. Not observed to fix anything yet.
