[Nouveau] Status of GF108GLM [NVS 5200M]

[Jesús J. Guerrero Botella]

Hi, Ilia.

Sorry for such a big delay in answering. Real life and that stuff...

I am a newcomer so, please, if I do something wrong regarding my
quoting style or whatever, just let me know and I'll quickly improve. :)

Yes, it comes up in 07 when I launch, let's say glxgears in DRI_PRIME=1.
It performs similarly to the intel chip, or maybe a bit worse.
For the rest, yes, it mostly works. But it's no good of course.

I fetched that and tried to compile it. First failed because of missing envyas,
which I compiled and installed. Then failed with some undefined symbol kind
of error which right now I don't have the time to diagnose.

If I can get this to compile I'll get back to this thread. Any recommendations
on kernel version, compiler or whatever might work better for that branch
is welcome though.
