drm/amdgpu: skip ASIC reset for APUs when go to S4

2023-03-23T13:29:55Z

For GC IP v11.0.4/11, PSP TMR need to be reserved for ASIC mode2 reset. But for S4, when psp suspend, it will destroy the TMR that fails the ASIC reset.

drm/amd: Don't allow s0ix on APUs older than Raven

2023-02-23T22:35:58Z

APUs before Raven didn't support s0ix. As we just relieved some of the safety checks for s0ix to improve power consumption on APUs that support it but that are missing BIOS support a new blind spot was introduced that a user could "try" to run s0ix. Plug this hole so that if users try to run s0ix on anything older than Raven it will just skip suspend of the GPU.

drm/amdgpu: add S/G display parameter

2023-02-09T15:30:36Z

Some users have reported flickerng with S/G display. We've tried extensively to reproduce and debug the issue on a wide variety of platform configurations (DRAM bandwidth, etc.) and a variety of monitors, but so far have not been able to. We disabled S/G display on a number of platforms to address this but that leads to failure to pin framebuffers errors and blank displays when there is memory pressure or no displays at all on systems with limited carveout (e.g., Chromebooks). Add a option to disable this as a debugging option as a way for users to disable this, depending on their use case, and for us to help debug this further. v2: fix typo Reviewed-by: Harry Wentland Acked-by: Christian König Signed-off-by: Alex Deucher

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

2023-01-31T18:59:21Z

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
