Bug ID 106188
Summary Can't successfully set pstates in pp_od_clk_voltage
Product DRI
Version unspecified
Hardware x86-64 (AMD64)
OS Linux (All)
Status NEW
Severity normal
Priority medium
Component DRM/AMDgpu

Hello,
I specified "amdgpu.ppfeaturemask=3D0xffffffff" as a boot paramet=
er so I could
access "/sys/class/drm/card0/device/pp_od_clk_voltage".
The pstate table for source and memory clocks looks correct.

When I run "echo "s 7 1209 900" /sys/class/drm/card0/device/=
pp_od_clk_voltage",
it returns "s 7 1209 900 /sys/class/drm/card0/device/pp_od_clk_voltage=
".
When I run "echo "c" /sys/class/drm/card0/device/pp_od_clk_v=
oltage" afterwards,
it returns "c /sys/class/drm/card0/device/pp_od_clk_voltage".

However, the change is not applied. When I do "cat
/sys/class/drm/card0/device/pp_od_clk_voltage", it still says "7:=
       1196Mhz
      1006 mV".
And when I run "watch -n 0.5  cat /sys/kernel/debug/dri/0/amdgpu_pm_in=
fo", it
reports
"       1196 MHz (SCLK)
        981 mV (VDDGFX)
".

Am I making a mistake somewhere or should it work like this?

I also tried "echo "manual" >
/sys/class/drm/card0/device/power_dpm_force_performance_level" and set=
ting
pstates 5-7, but that didn't help either.
In the documentation, I read that pp_od_clk_voltage should also include
OD_range, but it's not there for me.
