Bug ID 107143
Summary Prime - OverDrive volt and frequency table(pp_od_clk_voltage) is reset every time on power on
Product DRI
Version unspecified
Hardware x86-64 (AMD64)
OS Linux (All)
Status NEW
Severity normal
Priority medium
Component DRM/AMDgpu

OverDrive volt and frequency table(pp_od_clk_voltage) is reset every time on
power on.
For most desktop this is not a problem since, the GPU is not powered off until
you turn off the computer.

When you use PRIME, the dGPU is powered off every time you stop using it, which
again means that next time it is powered all OverDrive table changes will be
lost.


Distro: Debian
Kernel: 4.17.3(custom)
Machine: HP ZBook 15 G4 Mobile Workstation.
CPU: i7-7700HQ
dGPU: AMD Radeon Pro WX 4150
