*	PCI: hv: Add arm64 Hyper-V vPCI support	Sunil Muthuswamy	2022-01-12	1	-0/+9
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Add arm64 Hyper-V vPCI support by implementing the arch specific interfaces. Introduce an IRQ domain and chip specific to Hyper-v vPCI that is based on SPIs. The IRQ domain parents itself to the arch GIC IRQ domain for basic vector management.

*	arm64: hyperv: Add Hyper-V hypercall and register access utilities	Michael Kelley	2021-08-04	1	-0/+69
	hyperv-tlfs.h defines Hyper-V interfaces from the Hyper-V Top Level Functional Spec (TLFS), and #includes the architecture-independent part of hyperv-tlfs.h in include/asm-generic. The published TLFS is distinctly oriented to x86/x64, so the ARM64-specific hyperv-tlfs.h includes information for ARM64 that is not yet formally published. The TLFS is available here: docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/tlfs mshyperv.h defines Linux-specific structures and routines for interacting with Hyper-V on ARM64, and #includes the architecture- independent part of mshyperv.h in include/asm-generic. Use these definitions to provide utility functions to make Hyper-V hypercalls and to get and set Hyper-V provided registers associated with a virtual processor.
