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