9650M GT / FreeBSD 8.0 / 195.22beta / amd64
 
Hello,

I have a 9650M GT on an Asus M70Vn laptop.

This card on this laptop is known to crash X (in my case the whole system) with the official nVidia drivers later than 173, under Linux (and FreeBSD)

In order to have my graphic card working under linux, I have to load the module with option NVreg_RegistryDwords="PerfLevelSrc=0x2222" wich forces "Performance Mode" for PowerMizer. It works fine with debian packaged 190.42 nVidia non-free driver

Under FreeBSD, it seems that I have to use the sysctl hw.nvidia.registry.dwords, but setting it to "PerfLevelSrc=0x2222" doesn't force performance mode.
Setting it manually whit nvidia-settings at starting X works (my system doesn't crash anymore), so it's the right workaround.
How can I force Performance Mode? (either using sysctl or any other way?)

BTW: All my OSes are amd64, if it matters

Thanks in advance,
Romain

I have found a workaround under FreeBSD using xorg.conf :

Section Device
[...]
Option ""RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerDefault=0x2 PowerMizerDefaultAC=0x2"

The driver stays in max performance mode (0x3) although I did set it to medium (PowerMizerDefaultAC=0x2), but X/system doesn't crash anymore.
Setting these options trough sysctl hw.nvidia.registry.dwords doesn't word.

Romain
