Describe the problem rocm-smi --setslevel doesn't work

Do you accept these terms? [y/N] y Unable to write to sysfs file /sys/class/drm/card0/device/pp_od_clk_voltage

I tried to vim the file using root privilege, and I failed again. Could you guys give an idea what's the possible problem?

Did you turn on OverDrive in the ppfeaturemask of your driver?

For instance, the default ppfeaturemask in kernel 4.20 is 0xfffd3fff. Bit 14 is OverDrive. So setting amdgpu.ppfeaturemask=0xfffd7fff on your grub boot line.

@jlgreathouse Thank you so much! I added amdgpu.ppfeaturemask=0xfffd7fff in grub.cfg and everything starts to work now.
