From 4790c4ae2489b8c72e6d98f3f80b5a9e7f799203 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 7 Dec 2011 14:49:45 -0800 Subject: [PATCH] i965: Add separate stencil/HiZ setup for MESA_FORMAT_Z32_FLOAT_X24S8. This is a little more unusual than the separate MESA_FORMAT_S8_Z24 support, because in addition to storing the real stencil data in a MESA_FORMAT_S8 miptree, we also make the Z miptree be MESA_FORMAT_Z32_FLOAT instead of the requested format.
