[PATCH v2 0/7] xen/arm: Unbreak ACPI

Posted by Julien Grall 3 years, 6 months ago

From: Julien Grall <jgrall@amazon.com>

Hi all,

Xen on ARM has been broken for quite a while on ACPI systems. This
series aims to fix it.

This series also introduced support for ACPI 5.1. This allows Xen to
boot on QEMU.

I have only build tested the x86 side so far.

Cheers,

Julien Grall (7):
  xen/acpi: Rework acpi_os_map_memory() and acpi_os_unmap_memory()
  xen/arm: acpi: The fixmap area should always be cleared during
    failure/unmap
  xen/arm: Check if the platform is not using ACPI before initializing
    Dom0less
  xen/arm: Introduce fw_unreserved_regions() and use it
  xen/arm: acpi: add BAD_MADT_GICC_ENTRY() macro
  xen/arm: gic-v2: acpi: Use the correct length for the GICC structure
  xen/arm: acpi: Allow Xen to boot with ACPI 5.1

On a Tianocore-utilizing Raspberry PI 4B, this series allows successful
boot (some other distinct issues remain).  As such, for the series on an
ARM device:
