amd_iommu: Send notification when invalidate interrupt entry cache
|
|
|
|
In order to support AMD IOMMU interrupt remapping emulation with PCI
|
|
pass-through devices, QEMU needs to notify VFIO when guest IOMMU driver
|
|
updates and invalidate the guest interrupt remapping table (IRT), and
|
|
communicate information so that the host IOMMU driver can update
|
|
the shadowed interrupt remapping table in the host IOMMU.
|
|
|
|
Therefore, send notification when guest IOMMU emulates the IRT
|
|
invalidation commands.
