Subject: [PATCH] fixes to drm-next - TTM DMA code (v1)
Date: Mon, 12 Dec 2011 15:09:26 -0500 [thread overview]
Message-ID: <1323720569-15435-1-git-send-email-konrad.wilk@oracle.com> (raw)
Jerome pointed me to some accounting error in the DMA API debugging code and
while I can't figure it out yet, I did notice some extreme slowness - which
is due to the nouveau driver calling the unpopulate (now that unbind +
unpopulate are squashed) quite a lot (this is using Gnome Shell - I think GNOME2
did not have those issues but I can't recall).
Anyhow these patches fix the 50% perf regression I saw and also some minor bugs
that I noticed.
