From 51b38106d74b1bd4fa2ce552f489c374bdffa812 Mon Sep 17 00:00:00 2001 From: Jordan Justen Date: Tue, 9 Jul 2013 15:16:35 -0700 Subject: [PATCH] i965/gen6 depth surface: calculate depth (array size) for depth surface (bc1acaa for gen6) This will be used in 3DSTATE_DEPTH_BUFFER in a later patch. Note: Cube maps are treated as 2D arrays with 6 times as many array elements as the cube map array would have.
