Just another ping...
Daniel, Dave - maybe you could give some advise on that ?
P.S I tried with Intel card (i915) driver on 4.18.1 kernel to do the same to get some reference point, but it just hanged.

One of the problems I encountered was hitting WARNs in amdgpu_gem_force_release. It complaints about still open client FDs and BOs allocations which is obvious since
we didn't let user space clients know about the device removal and hence they won't release allocations and won't close their FDs.
Question - how other drivers handle this use case, especially eGPUs since they indeed may be extracted in any moment, is there any way to notify Xorg and other clients about this so they may
have a chance to release all their allocations and probably terminate ? Maybe some kind of uevent ?
