drm/amdgpu: Use RMW accessors for changing LNKCTL

2023-08-21T19:11:35+00:00

Don't assume that only the driver would be accessing LNKCTL. ASPM policy changes can trigger write to LNKCTL outside of driver's control. And in the case of upstream bridge, the driver does not even own the device it's changing the registers for. Use RMW capability accessors which do proper locking to avoid losing concurrent updates to the register value.

drm/amd: Refactor `amdgpu_aspm` to be evaluated per device

2022-02-17T20:59:05+00:00

Evaluating `pcie_aspm_enabled` as part of driver probe has the implication that if one PCIe bridge with an AMD GPU connected doesn't support ASPM then none of them do. This is an invalid assumption as the PCIe core will configure ASPM for individual PCIe bridges. Create a new helper function that can be called by individual dGPUs to react to the `amdgpu_aspm` module parameter without having negative results for other dGPUs on the PCIe bus.

drm/amdgpu: don't do resets on APUs which don't support it

2022-01-14T23:06:44+00:00

It can cause a hang. This is normally not enabled for GPU hangs on these asics, but was recently enabled for handling aborted suspends. This causes hangs on some platforms on suspend.
