[Bug 107143] Prime - OverDrive volt and frequency table(pp_od_clk_voltage) is reset every time on power on
https://bugs.freedesktop.org/show_bug.cgi?id=107143
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 Assignee: dri-devel@lists.freedesktop.org Reporter: rune@megahurts.dk
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
