drm/amdgpu: enable pdb0 for hibernation on SRIOV

2025-06-18T16:19:15Z

When switching to new GPU index after hibernation and then resume, VRAM offset of each VRAM BO will be changed, and the cached gpu addresses needed to updated. This is to enable pdb0 and switch to use pdb0-based virtual gpu address by default in amdgpu_bo_create_reserved(). since the virtual addresses do not change, this can avoid the need to update all cached gpu addresses all over the codebase.

drm/amdkfd: Support chain runlists of XNACK+/XNACK-

2025-05-16T17:37:29Z

If the MEC firmware supports chaining runlists of XNACK+/XNACK- processes, set SQ_CONFIG1 chicken bit and SET_RESOURCES bit 28. When the MEC/HWS supports it, KFD checks the XNACK+/XNACK- processes mix happens or not. If it does, enter over-subscription.

drm/amdgpu: Check gmc requirement for reset on init

2024-10-15T15:16:32Z

Add a callback to check if there is any condition detected by GMC block for reset on init. One case is if a pending NPS change request is detected. If reset is done because of NPS switch, refresh NPS info from discovery table. Signed-off-by: Lijo Lazar Reviewed-by: Feifei Xu Signed-off-by: Alex Deucher

drm/amdgpu: Place NPS mode request on unload

2024-10-15T15:16:20Z

If a user has requested NPS mode switch, place the request through PSP during unload of the driver. For devices which are part of a hive, all requests are placed together. If one of them fails, revert back to the current NPS mode. Signed-off-by: Lijo Lazar Signed-off-by: Rajneesh Bhardwaj Reviewed-by: Feifei Xu Signed-off-by: Alex Deucher

drm/amdgpu: Add sysfs interfaces for NPS mode

2024-10-07T18:32:23Z

Add a sysfs interface to see available NPS modes to switch to - cat /sys/bus/pci/devices/../available_memory_paritition Make the current_memory_partition sysfs node read/write for requesting a new NPS mode. The request is only cached and at a later point a driver unload/reload is required to switch to the new NPS mode. Ex: echo NPS1 > /sys/bus/pci/devices/../current_memory_paritition echo NPS4 > /sys/bus/pci/devices/../current_memory_paritition The above interfaces will be available only if the SOC supports more than one NPS mode. Also modify the current memory partition sysfs logic to be more generic. Signed-off-by: Lijo Lazar Reviewed-by: Rajneesh Bhardwaj Signed-off-by: Alex Deucher
