[Xen-devel] [PATCH 00/14] Xen ARM DomU ACPI support

[Shannon Zhao <zhaoshenglong@xxxxxxxxxx>]

From: Shannon Zhao <shannon.zhao@xxxxxxxxxx>

The design of this feature is described as below.
Firstly, the toolstack (libxl) generates the ACPI tables according the
number of vcpus and gic controller.

Then, it copies these ACPI tables to DomU memory space and passes
them to UEFI firmware through the "ARM multiboot" protocol.

At last, UEFI gets the ACPI tables through the "ARM multiboot" protocol
and installs these tables like the usual way and passes both ACPI and DT
information to the Xen DomU.

Currently libxl only generates RSDP, XSDT, GTDT, MADT, FADT, DSDT tables
since it's enough now.

This has been tested using guest kernel with the Dom0 ACPI support
patches which could be fetched from:
https://git.kernel.org/cgit/linux/kernel/git/mfleming/efi.git/log/?h=efi/arm-xen

Shannon Zhao (14):
  libxl/arm: Fix the function name in error log
  libxl/arm: Factor out codes for generating DTB
  libxc: Add placeholders for ACPI tables blob and size
  tools: add ACPI tables relevant definitions
  libxl/arm: Construct ACPI GTDT table
  libxl/arm: Construct ACPI FADT table
  libxl/arm: Construct ACPI DSDT table
  libxl/arm: Construct ACPI MADT table
  libxl/arm: Construct ACPI XSDT table
  libxl/arm: Construct ACPI RSDP table
  libxl/arm: Initialize domain param HVM_PARAM_CALLBACK_IRQ
  libxl/arm: Add ACPI module
  libxl/arm: initialize memory information of ACPI blob
  libxc/xc_dom_core: Copy ACPI tables to guest memory space
