Author: Kenneth Graunke <[email protected]> Date: Tue Aug 13 13:54:37 2013 -0700 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.
