From 3aa51e02d6659c8f2e34a4153ae140a4f90cc51b Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Mon, 4 Apr 2016 00:45:25 -0700 Subject: [PATCH] i965: Allow 8x MSAA on >= 64bpp formats on Gen8+. See commit 3b0279a69 - this restriction is documented in the "Surface Format" field of RENDER_SURFACE_STATE. Looking at newer documentation, this restriction appears to exist on Haswell, but no longer applies on Gen8+.
