Message-Id: <1344060045-784-1-git-send-email-rydberg@euromail.se> Date: Sat, 4 Aug 2012 08:00:45 +0200 From: "Henrik Rydberg" <rydberg@...omail.se> To: Ben Skeggs <bskeggs@...hat.com> Cc: Dave Airlie <airlied@...il.com>, nouveau@...ts.freedesktop.org, dri-devel@...ts.freedesktop.org, linux-kernel@...r.kernel.org, Henrik Rydberg <rydberg@...omail.se> Subject: [PATCH] nouveau: Do not use nva3 engine for 0xaf chipset The nva3 copy engine exhibits random memory corruption in at least one case, the GeForce 320M (nv50, 0xaf) in the MacBookAir3,1. This patch omits creating the engine for the specific chipset, falling back to M2MF, which kills the symptoms. Signed-off-by: Henrik Rydberg <rydberg@...omail.se> --- Hi Ben, this patch is still needed in 3.6-rc1, so perhaps we should apply it after all. I have been running it without problems for a long time now.
