Subject: [PATCH 1/8] drm/i915: Program RPCS for Broadwell
Date: Tue, 14 Aug 2018 15:40:51 +0100	[thread overview]
Message-ID: <20180814144058.19286-2-tvrtko.ursulin@linux.intel.com> (raw)
In-Reply-To: <20180814144058.19286-1-tvrtko.ursulin@linux.intel.com>

From: Chris Wilson <chris@chris-wilson.co.uk>

Currently we only configure the power gating for Skylake and above, but
the configuration should equally apply to Broadwell and Braswell. Even
though, there is not as much variation as for later generations, we want
to expose control over the configuration to userspace and may want to
opt out of the "always-enabled" setting.
