I guess reclocking is supposed to work with Linux 3.13 with Fermi cards (I have
a GT 540M), but it doesn't seem to on mine:

# cat /sys/class/drm/card0/device/pstate 
03: core 50 MHz memory 135 MHz
07: core 202 MHz memory 324 MHz
0f: core 672 MHz memory 800 MHz
--: core 0 MHz memory 0 MHz *

# echo "0f" > /sys/class/drm/card0/device/pstate 
bash: echo: erreur d'écriture : Fonction non implantée

It means in English:
bash: echo: write error : Function not implemented

Am I doing anything wrong ?

I'm on ArchLinux.
linux-mainline 3.13rc1-1
nouveau-dri 9.2.3-2
