KMS open still set per pasid-vm bindings per adev (socket) so I
don’t see how the per-partition overwrite PASID issue is primarily
a KFD concern.
Are you saying the KFD process devices holds a shadow copy of the
correct VM during page restore during fault?
Doesn’t it acquire the wrong VM object on process init in the
first place?
Even if it were the case the KFD had a separate VM reference, the
underlying IRQ fault handling is still broken.
We probably don’t want to bandage over something to fix one symptom.

Currently multiple partitions will incorrectly
overwrite the VM lookup
table since the table is indexed by PASID and
multiple partitions can
register different VM objects on the same PASID.
That's a rather bad idea. Why do we have the same
PASID for different VM
objects in the first place?
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.
Yeah, Felix and I designed that.
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.
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.
As far as I can see that is the fundamental problem. This
needs to be fixed instead.
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.
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.
Regards,
Philip
Yeah that is pretty much a no-go.
The PASID and how it is used is defined by the PCIe
specifications. If we now start to assign multiple VMs to the
same PASID then we are violating the PCIe specification.
The problems you see are most likely just the tip of the
iceberg here.
Regards,
Christian.
Jon
Regards,
Christian.
This results in loading the wrong VM object on
PASID query.
To correct this, setup the lookup table to be
per-partition-per-PASID
instead.
