[edk2][PATCH v2 0/2] ACPI table defailt for Aarch64

[Samer El-Haj-Mahmoud]

Set the default value of PcdAcpiExposedTableVersions for Aarch64
platforms to 0x20 to indicate ACPI 5.0.

[edk2][PATCH v2 1/2] MdeModulePkg: PcdAcpiExposedTableVersions default for Arm64 platforms

[Samer El-Haj-Mahmoud]

Set the default value of PcdAcpiExposedTableVersions for Aarch64
platforms to 0x20. Previously, the default was set to 0x3E for all
platforms. The new value removes ACPI 1.0b compatability, which forces
the use of XSDT 64-bit pointer, as required by Arm SBBR specification.
This also resolves an error reported by acpiview command, as seen on
the RPi (see https://github.com/pftf/RPi4/issues/25).

should we consider your R-b on the first patch sufficient for pushing?

You are marked as "R" for "MdeModulePkg: ACPI modules", but technically
speaking, "MdeModulePkg.dec" needs an ACK from either Jian or Hao.

Content-wise, your approval looks sufficient, but I don't want to
assume. Please confirm.

Thank

[Dandan Bi]

Hi Laszlo,

I think it should be Ok.
But if can get ACK/R-B from the maintainer of MdeModulePkg, that would be better, which follows process more.


Thanks,
Dandan

Re: [edk2-devel] [edk2][PATCH v2 1/2] MdeModulePkg: PcdAcpiExposedTableVersions default for Arm64 platforms

[Liming Gao]

Laszlo:
  I understand Module reviewer R-B is enough for the patch.

  R: Package Reviewer: Cc address for patches and questions. Reviewers help
     maintainers review code, but don't have push access. A designated Package
     Reviewer is reasonably familiar with the Package (or some modules
     thereof), and/or provides testing or regression testing for the Package
     (or some modules thereof), in certain platforms and environments.

Thanks
Liming

Series pushed and merged as #535

Thanks all

[edk2][PATCH v2 2/2] Revert "ArmVirtPkg/ArmVirtQemu: limit ACPI support to v5.0 and higher"

[Samer El-Haj-Mahmoud]

This reverts commit e0692789058ee2c0099f88852503c16dbb0bae4e.

The default value for PcdAcpiExposedTableVersions is now set to 0x20
for Aarch64 systems. Setting this PCD in ArmVirtPkg/ArmVirtQemu.dsc
is no longer necessary.
