BugLink: https://bugs.launchpad.net/bugs/2072428 [Impact] AMD GPUs like RX580 and RX5500 failed to be initialized after commit: 466a7d115326 ("drm/amd: Use the first non-dGPU PCI device for BW limits") The screen stays blank. [Fix] Set the current speed/width on devices. Upstream fix: ba46b3bda296 ("drm/amdgpu: Adjust logic in amdgpu_device_partner_bandwidth()") [Test] Bug reporter tested on hardware, amdgpu works fine. Also verified on AMD iGPU of laptop by myself. glmark2 works fine. [Where problems could occur] It may break amdgpu.
