From 590d71791a50c9b2caebffa79ae4382c78deca80 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 7 Oct 2013 11:19:11 -0700 Subject: [PATCH] i965/blorp: Use R32_FLOAT for Z32F surfaces. Currently, all that matters is that we copy the correct number of bits, so any format that has 32-bits of data will work fine. Once BLORP begins handling format conversions, the sampler will need to correctly interpret the data. We don't need a depth format, but we do need the right number of components and data type (FLOAT). For Z32F, this means using R32_FLOAT.
