From 5849e0612cc4c21d213bdb4bd8d0a3f9531cc2b3 Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 30 Jul 2018 15:20:47 -0700 Subject: [PATCH] gallium/auxiliary: Add util_format_get_depth_only() helper. This will be used by u_transfer_helper.c shortly, in order to split packed depth-stencil into separate resources.
