Doesn't this require a kernel version that has your other patch? What happens when this runs on an older kernel? Does it get silently ignored, or does it end up erroring out? If it errors out, that's fine. Otherwise some sort of version check should be put in, no?
The corresponding kernel patch is already merged in Ben's tree. If running with an older kernel, this flag will be a no-op, which is fine since GK20A's GPU (the reason for this patch as you have guessed :)) is not enabled for these kernels.
I am fine with adding a version check if you think it is necessary.
So as discussed on IRC, I will check the DRM version from Mesa. This patch should be good to go - it will require a version increase in libdrm though. Let me know if you want me to send a patch for this too.
