[PATCH v3 0/2] Fix coherence for VMbus and PCI pass-thru devices in Hyper-V VM

2022-03-24 Thread Michael Kelley via iommu
Hyper-V VMs have VMbus synthetic devices and PCI pass-thru devices that are added dynamically via the VMbus protocol and are not represented in the ACPI DSDT. Only the top level VMbus node exists in the DSDT. As such, on ARM64 these devices don't pick up coherence information and default to not
