drm/amdgpu: vi: disable ASPM on Intel Alder Lake based systems

2022-05-06T20:57:28Z

Active State Power Management (ASPM) feature is enabled since kernel 5.14. There are some AMD Volcanic Islands (VI) GFX cards, such as the WX3200 and RX640, that do not work with ASPM-enabled Intel Alder Lake based systems. Using these GFX cards as video/display output, Intel Alder Lake based systems will freeze after suspend/resume. The issue was originally reported on one system (Dell Precision 3660 with BIOS version 0.14.81), but was later confirmed to affect at least 4 pre-production Alder Lake based systems. Add an extra check to disable ASPM on Intel Alder Lake based systems with the problematic AMD Volcanic Islands GFX cards.

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

2022-02-17T20:59:05Z

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

2022-01-14T23:06:44Z

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.
