Nouveau "Boost" Patches Show Much Performance Potential

I didn't mean the core clock.


I mean, the memory clocks.


If I try to relax it to, for instance, 03, after a 0f state, this is what I see :

03: core 300 MHz shader 600 MHz memory 100 MHz AC DC *
07: core 400 MHz shader 800 MHz memory 300 MHz
0f: core 576 MHz shader 1242 MHz memory 999 MHz
AC: core 300 MHz shader 601 MHz memory 999 MHz

And dmesg shows me "nouveau 0000:01:00.0: fb: Could not calculate MR" when I try a lower pstate.

Don't happen when I switch to a higher.



PS : GTX 260, Linux 4.4, 64 bit.

Mhh this is Tesla. I never looked into it, but I guess the issue is something trivial. You should open a bug if you didn't do it already. And if nobody commented on that, ask again
