Not a real problem. If you want video decoding acceleration (h264
being the more useful format supported), follow the steps at
https://nouveau.freedesktop.org/VideoAcceleration.html#firmware .

Various Kepler boards can run into hangs which will come out as ctxsw
timeouts. If that becomes a thing, you can replace the nouveau ctxsw
fw with the nvidia one by running the firmware steps above (if you use
the 325.15 firmware) and adding nouveau.config=NvGrUseFW=1 to the boot
line. This has helped a bunch of people with stability.

If you want to switch performance levels, you can do so via
/sys/kernel/debug/dri/0/pstate (cat the file for the list of allowed
levels, and echo the level back in to switch to it). This is mostly
reliable, but we haven't added logic to do it in an automatic way (it
can also lead to a brief flicker).

Good luck.

Cheers,
