Subject: [PATCH 2/9] drm/i915: don't keep reassigning FBC_UNSUPPORTED
Date: Mon, 9 Feb 2015 14:46:28 -0200 [thread overview]
Message-ID: <1423500395-1787-3-git-send-email-przanoni@gmail.com> (raw)
In-Reply-To: <1423500395-1787-1-git-send-email-przanoni@gmail.com>
From: Paulo Zanoni <paulo.r.zanoni@intel.com>
This may save a few picoseconds on !HAS_FBC platforms. And it also
satisfies my OCD.
