Subject: [PATCH 3/6] drm/msm: Add MSM_PARAM_GMEM_BASE
Date: Tue, 7 Mar 2017 10:02:53 -0700 [thread overview]
Message-ID: <1488906176-10720-4-git-send-email-jcrouse@codeaurora.org> (raw)
In-Reply-To: <1488906176-10720-1-git-send-email-jcrouse-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>
User space needs to know where the GMEM whole starts so that they
can set up the addressing correctly.
