[Nouveau] Is binary firmware still necessary for GTX660 card (NVE0 family) in order to use DRM and/or VDPAU video acceleration?

[Matthias Nagel]

Hello,

I run the Gentoo Linux distribution and use a self-compiled Linux 3.10.17
kernel. According to

[1] http://nouveau.freedesktop.org/wiki/InstallDRM/
[2] http://nouveau.freedesktop.org/wiki/VideoAcceleration/

I need the original firmware from the binary driver in order to sucessully
use DRM and to use VDPAU video acceleration. I used the python script from
[2] and I had a look at the ebuild from

[3] https://bugs.gentoo.org/show_bug.cgi?id=480832

to extract the firmware and to place it at /lib/firmware/nouveau. But I do
not see any dmesg output about loading the firmware. I do not see any dmesg
output about nouveau failing to do so either. I neither do no see any
"nouveau <pci id>: firmware: requesting nouveau/" in my kernel output.

Anyway VDPAU seems to work. If I call mplayer with "-vo vdpau -vc
ffmpeg12vdpau,...", I don't get any error message and my CPU load drops
from 30% to 7% for a recent mpeg transport stream 1080p video.

In conclusion, do I still need the firmware? Do the information given at
[1], [2] still apply or are they outdated?

Thank you, Matthias
