Ok, this patch should work on NV50 chips also.
What you get is EXA and Xv.
You still need:
A recent -CURRENT or -STABLE.
git master of libdrm and xf86-video-nouveau.
Things I've figured out since the last patch...
On NV50 class hardware you need to have a compositing manager running
for Xv to work. That means xcompmgr, metacity with composite enabled,
xfce (rumored to work as well, haven't tried). If your running Gnome
with metacity, open gconf-editor and go to apps->metacity->general and
check the composite box.
On NV40 class hardware, you don't need the composite manager. In fact
(at least with Xserver 1.6 which I'm running now), if a composite
manager is enabled, I'm seeing high cpu utilization from Xorg under some
circumstances. I don't think this is a drm issue, but still an issue.
For me, if I start a video using mplayer in an xterm, cpu is fine as
long as that xterm is the foreground window. If it is not the
foreground window, even if it isn't obscured I see the cpu utilization.
Disabling the composite manager makes everything fine.
