Subject: iommu/amd: Call domain_flush_complete() in update_domain()
Git-commit: f44a4d7e4f1cdef73c90b1dc749c4d8a7372a8eb
Patch-mainline: v5.7-rc5
References: bsc#1172061
The update_domain() function is expected to also inform the hardware
about domain changes. This needs a COMPLETION_WAIT command to be sent
to all IOMMUs which use the domain.
