| Due to high latency in PCIE clock switching on RKL platforms,
switching the PCIE clock dynamically at runtime can lead to HDMI/DP
audio problems. On newer asics this is handled in the SMU firmware.
For SMU7-based asics, disable PCIE clock switching to avoid the issue.
AMD provide a parameter to disable PICE_DPM.
modprobe amdgpu ppfeaturemask=0xfff7bffb
It's better to contorl PCIE_DPM in amd gpu driver,
switch PCI_DPM by determining intel RKL platform for SMU7-based asics.
