| H A D | vhost-stub.c | ee071f67 Mon Jun 26 04:12:57 CDT 2023 Viktor Prutyanov <viktor@daynix.com> vhost: register and change IOMMU flag depending on Device-TLB state
The guest can disable or never enable Device-TLB. In these cases,
it can't be used even if enabled in QEMU. So, check Device-TLB state
before registering IOMMU notifier and select unmap flag depending on
that. Also, implement a way to change IOMMU notifier flag if Device-TLB
state is changed.
