Subject: [PATCH 5/8] drm/msm: Add $debugfs/gem stats on resident objects
Date: Mon, 5 Apr 2021 10:45:28 -0700 [thread overview]
Message-ID: <20210405174532.1441497-6-robdclark@gmail.com> (raw)
In-Reply-To: <20210405174532.1441497-1-robdclark@gmail.com>
From: Rob Clark <robdclark@chromium.org>
Currently nearly everything, other than newly allocated objects which
are not yet backed by pages, is pinned and resident in RAM. But it will
be nice to have some stats on what is unpinned once that is supported.
