2023-10-26drm/amd: Explicitly disable ASPM when dynamic switching disabledMario Limonciello1-1/+1
Currently there are separate but related checks: * amdgpu_device_should_use_aspm() * amdgpu_device_aspm_support_quirk() * amdgpu_device_pcie_dynamic_switching_supported() Simplify into checking whether DPM was enabled or not in the auto case. This works because amdgpu_device_pcie_dynamic_switching_supported() populates that value.

S2idle resume freeze can be observed on Intel ADL + AMD WX5500. This is caused by commit 0064b0ce85bb ("drm/amd/pm: enable ASPM by default"). The root cause is still not clear for now.

2022-05-06drm/amdgpu: vi: disable ASPM on Intel Alder Lake based systemsRichard Gong1-1/+16
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.

2022-02-17drm/amd: Refactor `amdgpu_aspm` to be evaluated per deviceMario Limonciello1-1/+1
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.
