Hi Julien, Rahul I've encountered a similar problem with IMX8 GPU recently. It wasn't probing properly after the domain reboot. After some digging, I came to the same solution as Rahul and found this thread. I also encountered the occasional "Unexpected global fault, this could be serious" error message when destroying a domain with an actively-working GPU.

Indeed after removing the arm_smmu_master_free_smes() call, both reboot and global fault issues are gone. If I understand correctly, device removing is not yet supported, so I can't find a proper place for the arm_smmu_master_free_smes() call. Should we remove the function completely or just left it commented for later or something else? Rahul, are you still working on this or could I send my patch? Regards, Mykyta
