Koba Ko b3dc549986 drm/amdgpu: Disable PCIE_DPM on Intel RKL Platform ... 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.
