Failed to restore when power cap is not available

[Cycatz]

/sys/class/drm/card0/device/hwmon/hwmon5/power1_cap doesn't not exist on my system, and it showed the error when running amdgpu-clocks restore:

Restoring all states to the initial defaults from /tmp/amdgpu-custom-states.card0.initial

And the file it tried to restore:

$ cat /tmp/amdgpu-custom-states.card0.initial

FORCE_POWER_CAP: 

My current workaround is to check if the value is empty before setting:

hi @Cycatz , thanks for reporting.

cat: /sys/class/drm/card0/device/hwmon/hwmon5/power1_cap: No such file or directory

That is very strange indeed, the power1_cap normally does exist. Let's check some things:

• What is your card, kernel version, driver variant?
• What is the content of your custom state file?
• What is the output of amdgpu-clock when you fist apply your custom state (clean state, after boot, before restore is attempted)?
• What does the find /sys/class/drm/card0/device/hwmon say (assuming your card is card0)?
