Subject: [21/48] drm/radeon/kms: disable writeback on pre-R300 asics
Date: Mon, 16 Jan 2012 10:44:48 -0800 [thread overview]
Message-ID: <20120116184517.564403034@clark.kroah.org> (raw)
In-Reply-To: <20120116184527.GA11972@kroah.com>
3.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher <alexander.deucher@amd.com>
commit 28eebb703e28bc455ba704adb1026f76649b768c upstream.
We often end up missing fences on older asics with
writeback enabled which leads to delays in the userspace
accel code, so just disable it by default on those asics.
