drm/amd/pm: fix a potential gpu_metrics_table memory leak

2021-12-22T08:30:54+00:00

[ Upstream commit aa464957f7e660abd554f2546a588f6533720e21 ] Memory is allocated for gpu_metrics_table in renoir_init_smc_tables(), but not freed in int smu_v12_0_fini_smc_tables(). Free it!

drm/amd/pm: Update intermediate power state for SI

2021-09-30T08:11:01+00:00

commit ab39d3cef526ba09c4c6923b4cd7e6ec1c5d4faa upstream. Update the current state as boot state during dpm initialization. During the subsequent initialization, set_power_state gets called to transition to the final power state. set_power_state refers to values from the current state and without current state populated, it could result in NULL pointer dereference. For ex: on platforms where PCI speed change is supported through ACPI ATCS method, the link speed of current state needs to be queried before deciding on changing to final power state's link speed. The logic to query ATCS-support was broken on certain platforms. The issue became visible when broken ATCS-support logic got fixed with commit f9b7f3703ff9 ("drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)").

drm/amdgpu: Disable PCIE_DPM on Intel RKL Platform

2021-09-26T12:08:59+00:00

[ Upstream commit b3dc549986eb7b38eba4a144e979dc93f386751f ] 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.
