Bug ID: 107518
Summary: polaris powerplay init fails: There must be 1 or more
PCIE levels defined in PPTable
Product: DRI
Version: unspecified
Hardware: PowerPC
OS: Linux (All)
Status: NEW
Severity: normal
Priority: medium
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org
Reporter: shawnanastasio@yahoo.com

dmesg for 4.17.11-200
When booting kernel 4.17 or 4.18-rc8+ (git) on a POWER9 system with an ASUS Rx
580 GPU, the following messages are printed to the kernel log:
[ 10.398837] amdgpu: [powerplay] There must be 1 or more PCIE levels defined
in PPTable.
[ 10.398839] amdgpu: [powerplay] Failed to populate SCLK during
PopulateNewDPMClocksStates Function!
[ 10.398840] amdgpu: [powerplay] Failed to populate and upload SCLK MCLK DPM
levels!
Note that the system is booted with the kernel argument `amdgpu.dc=0` to work
around this issue: https://bugs.freedesktop.org/show_bug.cgi?id=107049
GPU performance seems to be significantly hindered as a result of these errors.
Booting with `amdgpu.dpm=0` silences the errors but does not improve
performance.
