Bug ID	111128
Summary	Impossible to change pstate on GT610M
Product	Mesa
Version	19.1
Hardware	x86-64 (AMD64)
OS	Linux (All)
Status	NEW
Severity	normal
Priority	medium
Component	Drivers/DRI/nouveau
Assignee	nouveau@lists.freedesktop.org

QA Contact	nouveau@lists.freedesktop.org

Hello,
I have an asus UX32VD, with a GT610M inside, which works with the Optimus
architecture, handle by PRIME. The bug is currently with the kernel 5.2.0, =
but
it have always been like that as far as I remember.

uname -a :
Linux ga-laptop 5.2.0-arch2-1-ARCH #1 SMP PREEMPT Mon Jul 8 18:18:54 UTC 20=
19
x86_64 GNU/Linux

lspci :
01:00.0 3D controller: NVIDIA Corporation GF117M [GeForce 610M/710M/810M/82=
0M /
GT 620M/625M/630M/720M] (rev a1)

While it is not in use, nouveau shutdown the chipset as expected :
cat /sys/kernel/debug/dri/1/pstate
07: core 270 MHz memory 405 MHz
0f: core 625 MHz memory 900 MHz
DC: core 0 MHz memory 0 MHz

While an app is launched with DRI_PRIME=3D1, we can see that the chipset is=
 set
to 07 :
DRI_PRIME=3D1 glxgears &
cat /sys/kernel/debug/dri/1/pstate
07: core 270 MHz memory 405 MHz
0f: core 625 MHz memory 900 MHz
DC: core 270 MHz memory 324 MHz

But when I tried to reclock, I have an error :
echo 0f > /sys/kernel/debug/dri/1/pstate
-bash: echo: write error: Function not implemented

And I have this in dmesg:
[  351.283183] nouveau 0000:01:00.0: bus: MMIO write of ffff8c1f FAULT at
6013d4 [ IBUS ]
[  458.362570] nouveau 0000:01:00.0: bus: MMIO write of 0000001f FAULT at
6013d4 [ IBUS ]

Thanks
