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

[Matthias Nagel]

Hi Martin,
if you refer to my kernel version. 3.10.17 is the latest, stable version in
the official gentoo repository for the amd64 architeture. See here

[4] https://packages.gentoo.org/package/sys-kernel/gentoo-sources?full_cat

As long as I do not miss any features, I stay with the stable version.

Hence, if I understand you correctly, there are kernel version (newer than
some unknown point in time) that already include the firmware? If this is
the case, someone who knows the exact kernel version should mention that
point on

[1] http://nouveau.freedesktop.org/wiki/InstallDRM/
[2] http://nouveau.freedesktop.org/wiki/VideoAcceleration/
[3] https://bugs.gentoo.org/show_bug.cgi?id=480832

and update the information.

Matthias
