From 0dd356bb6ff556e064672b0aa70908ca4567c7ff Mon Sep 17 00:00:00 2001 From: Tvrtko Ursulin Date: Tue, 4 Oct 2016 09:29:22 +0100 Subject: [PATCH] drm/i915: Eliminate Gen9 special case If we insert blitter forcewake domain entries in the range table we can eliminate that special case and simplify the code in a few macros. This will enable more unification later.
