Summary "pp_od_clk_voltage" unavailable on Hawaii GPU (R9 3= 90)
Product DRI
Version XOrg git
Hardware x86-64 (AMD64)
OS Linux (All)
Status NEW
Severity enhancement

I have recently tried to overclock/undervolt my GPU (R9 390) w=
ithin Linux
thanks to the "amdgpu.ppfeaturemask=3D0xffffffff" boot parameter,=
 but
unfortunately the file "pp_od_clk_voltage" is not available after=
 a reboot.

Files "pp_dpm_mclk" and "pp_dpm_sclk" however show corr=
ect states and MHz,
except that they don't show voltage information. Changing
"power_dpm_force_performance_level" to manual allows me to make c=
hanges to
these files, I can force a state to be used and overclock it, but voltages
aren't showed and can't be modified.

I have read that Southern Island GPUs were not expected to get this feature
working, and I know Vega is compatible, but I can't find anywhere if Hawaii
(CIK) hardware should be able to expose this feature. I might be missing
something.

Is there any way to undervolt my GPU under Linux at the moment?

Specs:
OS: Arch Linux
Kernel: 5.2.11.arch1-1
Mesa: 19.1.6-1
Xorg: 1.20.5-2
Boot parameters: radeon.cik_support=3D0 amdgpu.cik_support=3D1 amdgpu.dpm=
=3D1
amdgpu.dc=3D1 amdgpu.ppfeaturemask=3D0xffffffff
GPU: [AMD/ATI] Hawaii PRO [Radeon R9 290/390] (rev 80)

Feel free to ask for more details and output if needed.

Thank you for your time.
