drm/amd: Move helper for dynamic speed switch check out of smu13

2023-08-03T08:23:47+00:00

commit 188623076d0f1a500583d392b6187056bf7cc71a upstream. This helper is used for checking if the connected host supports the feature, it can be moved into generic code to be used by other smu implementations as well.

drm/amdgpu: register a vga_switcheroo client for MacBooks with apple-gmux

[ Upstream commit d37a3929ca0363ed1dce02b2772cd5bc547ca66d ] Commit 3840c5bcc245 ("drm/amdgpu: disentangle runtime pm and vga_switcheroo") made amdgpu only register a vga_switcheroo client for GPU's with PX, however AMD GPUs in dual gpu Apple Macbooks do need to register, but don't have PX. Instead of AMD's PX, they use apple-gmux. Use apple_gmux_detect() to identify these gpus, and pci_is_thunderbolt_attached() to ensure eGPUs connected to Dual GPU Macbooks don't register with vga_switcheroo.

drm/amdgpu/nv: Apply ASPM quirk on Intel ADL + AMD Navi

commit 2b072442f4962231a8516485012bb2d2551ef2fe upstream. 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. So extend and apply the ASPM quirk from commit e02fe3bc7aba ("drm/amdgpu: vi: disable ASPM on Intel Alder Lake based systems"), to workaround the issue on Navi cards too.

Revert "drm/amdgpu: TA unload messages are not actually sent to psp when amdgpu is uninstalled"

2023-03-10T08:33:59+00:00

[ Upstream commit 39934d3ed5725c5e3570ed1b67f612f1ea60ce03 ] This reverts commit fac53471d0ea9693d314aa2df08d62b2e7e3a0f8. The following change: move the drm_dev_unplug call after amdgpu_driver_unload_kms in amdgpu_pci_remove. The reason is the following: amdgpu_pci_remove calls drm_dev_unregister and it should be called first to ensure userspace can't access the device instance anymore. If we call drm_dev_unplug after amdgpu_driver_unload_kms then we observe IGT PCI software unplug test failure (kernel hung) for all ASICs. This is how this regression was found. After this revert, the following commands do work not, but it would be fixed in the next commit: - sudo modprobe -r amdgpu - sudo modprobe amdgpu Signed-off-by: Vitaly Prosyak Reviewed-by Alex Deucher Signed-off-by: Alex Deucher Signed-off-by: Sasha Levin
