From fd4daa9cea025ddf8623db289e79d264e9fa66f6 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Tue, 27 Aug 2013 17:04:17 +0100 Subject: drm/i915: Track pfit enable state separately from size Detangle the additional state of whether or not the hw has the pfit enabled from whether it has zero size. This allows us to cleanly distinguish in the code when we expect the pfit to be enabled (for Haswell pc8), and when the BIOS is confused and needs sanitizing.
