amdgpu: Ignore KFD eviction fences
invalidating preemptible DMABuf imports
Hi Felix,
I tested your patch on mGPU systems. It doesn't break any KFD
eviction tests, because tests don't allocate DMABuf import, that
doesn't trigger it's eviction fence. The only thing the patch
affects is in re-mapping

Hi Felix,
I tested your patch on mGPU systems. It doesn't break any KFD eviction
tests, because tests don't allocate DMABuf import, that doesn't trigger
it's eviction fence. The only thing the patch affects is in re-mapping
DMABuf imports that the eviction will still be triggered.

Hi Eric,
Can you try if the attached patch fixes the problem without breaking the
eviction tests on a multi-GPU PCIe P2P system?
Thanks,
