Why do we have the same PASID for different VM objects in the first place? </blockquote> Alex can probably elaborate on the KGD side, but from what I can see, the KMS driver open call has always assigned a new VM object per PASID on an open call. The KFD acquires and replaces the KGD PASID-VMID registration on its own compute process open/creation call. If this is the bad_idea you're referring to, then someone else will have to chime in. I don't have much history on this unfortunately. </blockquote> Yeah, Felix and I designed that. </blockquote> app opens drm node to create vm for each partition, with different vm->pasid for each vm, issue is from kfd_ioctl_acquire_vm -> kfd_process_device_init_vm -> amdgpu_amdkfd_gpuvm_set_vm_pasid, to replace all vm->pasid with kfd process->pasid, which is from open kfd node. This ends up to store only one vm to adev->vm_manager.pasids with KFD process pasid, so we cannot retrieve correct vm from adev->vm_manager.pasids on mGPUs or multiple partitions. <blockquote type="cite" cite="mid:5c26a4aa-d18d-4e36-98a9-b915644cb853@amd.com"> <blockquote type="cite">That aside, the current problem is, is that all KFD device structures are logical partitions and register their PASID-VM binding using this concept of a device. </blockquote> As far as I can see that is the fundamental problem. This needs to be fixed instead. <blockquote type="cite">On the KGD side however, the registration table is maintained in the adev struct, which is a physical socket. So there's a mismatch in understanding of what a device is between the KFD & KGD with regard to the look up table that results in bad bindings. Adding a per-partition dimension to the existing lookup table resolves issues where seeing, for example, with memory violation interception and XNACK i.e bad bindings result in wrong vm object found to set no-retry flags on memory violations. </blockquote> </blockquote> svm_range_restore_pages retry fault recover uses fault pasid to get kfd process, and use the fault node_id to get pdd->vm, maybe you can use this way to fix the debugger issue.
