Date: Tue, 14 May 2024 15:43:47 -0700	[thread overview]
Message-ID: <20240514224508.212318-1-romank@linux.microsoft.com> (raw)

This patch set enables the Hyper-V code to boot on ARM64 inside a Virtual Trust
Level. These levels are a part of the Virtual Secure Mode documented in the
Top-Level Functional Specification available at
https://learn.microsoft.com/en-us/virtualization/hyper-v-on-windows/tlfs/vsm

[V2]
    - Decreased number of #ifdef's
    - Updated the wording in the commit messages to adhere to the guidlines
    - Sending to the correct set of maintainers and mail lists

Roman Kisel (6):
  arm64/hyperv: Support DeviceTree
  drivers/hv: Enable VTL mode for arm64
  drivers/hv: arch-neutral implementation of get_vtl()
  arm64/hyperv: Boot in a Virtual Trust Level
  drivers/hv/vmbus: Get the irq number from DeviceTree
  drivers/pci/hyperv/arm64: vPCI MSI IRQ domain from DT
