Bug ID: 89113
Summary: NVA8 constantly flickers when clocked to lowest pstate
Product: xorg
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: Driver/nouveau
Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
Reporter: charleszhang77-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org

VBIOS
with stock nouveau from kernel 3.19.0-1.fc22.x86_64
this nva8 came with a thinkpad t410
my pstate file looks like this:
03: core 135 MHz shader 270 MHz memory 135 MHz
07: core 405 MHz shader 810 MHz memory 405 MHz
0f: core 606 MHz shader 1468 MHz memory 790 MHz
AC: core 405 MHz shader 810 MHz memory 405 MHz
when clocking to 07 or 0f everything works.
however, when clocking to pstate=03 i get constant flickering (maybe <5-10 hz),
although the clocks do change, and nothing crashes. (i can change clocks back
to 07 or 0f with no more flickering)
vbios attached
mmiodump where i fumbled around with powermizer while the blob reclocked
(no second monitor attached):

Look in nvidia-settings which clocks the blob sets when you plug your external screen in: most likely it will automatically go from level 03 to level 07 and won't go back to 03 unless you unplug the external screen.

That makes a lot of sense; unplugging an external monitor fixes the issue. I guess it's just a hardware limitation then. The blob does indeed avoid 03 with an extra monitor attached. Thanks for the help! That'd be another thing to worry about if dynamic power scaling were ever implemented for nouveau then. -- You are receiving this mail because: You are the assignee for the bug.
