Subject: [PATCH] drm/i915: Apply headless DMC workaround for CNL
Date: Thu, 11 Jan 2018 08:24:17 +0000 [thread overview]
Message-ID: <20180111082417.795-1-tvrtko.ursulin@linux.intel.com> (raw)
From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>
With firmware 1.07 having fixed the state corruption issue, we can enable
the headless GT performance workaround for CNL as well. (Equivalent to
b68763741aa2 ("drm/i915: Restore GT performance in headless mode with DMC
loaded") on other affected platforms.)
Signed-off-by: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Testcase: igt/gem_exec_nop/headless
