pp_od_clk_voltage is empty with 7900 XTX
Brief summary of the problem:
Despite having amdgpu.ppfeaturemask=0xffffffff
on my kernel command line i cannot read/write pp_od_clk_voltage. The file exists but reading it returns nothing. Writing to it does not seem to have any effect either. There is nothing in dmesg related to this.
