This series enables Linux guests running on Hyper-V on ARM64 hardware. New ARM64-specific code in arch/arm64/hyperv initializes Hyper-V and its hypercall mechanism. Existing architecture independent drivers for Hyper-V's VMbus and synthetic devices just work when built for ARM64. Hyper-V code is built and included in the image and modules only if CONFIG_HYPERV is enabled.[...]quoted
Hyper-V on ARM64 runs with a 4 Kbyte page size, but allows guests with 4K/16K/64K page size. Linux guests with this patch series work with all three supported ARM64 page sizes. The Hyper-V vPCI driver at drivers/pci/host/pci-hyperv.c has x86/x64-specific code and is not being built for ARM64. Enabling Hyper-V vPCI devices on ARM64 is in progress via a separate set of patches. This patch set is based on the linux-next20210720 code tree.Is it possible to rebase this on top of -rc3? Are there any dependencies or do you plan to upstream this via a different tree?
Some prerequisite patches are in hyperv-next. https://git.kernel.org/pub/scm/linux/kernel/git/hyperv/linux.git/log/?h=hyperv-next Wei.
