Nope, not supposed to work. Feel free to apply the equivalent of http://cgit.freedesktop.org/~darktama/nouveau/commit/?h=devel-pm&id=ffbf93ba1eb5f05d22bd5419e5f314188801155b to your kernel, and if you want memory reclocking in addition to engine reclocking, you can boot with nouveau.config=NvMemExec=1. However at this point we're not interested in whether it works or not -- it (probably) doesn't on a whole bunch of cards. Thanks. It doesn't work on my 8800GT either (used to work with the older performance_level setting), I guess this'll solve it as well? |

Created attachment 89753 [details] kernel log 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 Best regards,
