[edk2-devel] [PATCH v2 0/5] Fix OvmfXen HVM Direct kernel boot failure

[Lin, Gary (HPS OE-Linux)]

When using HVM Direct kernel boot with OvmfXen, it could fail at the
S3BootScript due to the inconsistency between QemuFwCfgS3Enabled()
and PcdAcpiS3Enable. Besides, QemuKernelLoaderFsDxe wasn't included
in OvmfXen, so the firmware couldn't fetch kernel/initrd from fw_cfg.

This patch series initializes PcdAcpiS3Enable and adds
QemuKernelLoaderFsDxe into OvmfXen. Besides, QemuFwCfgS3Enabled() is
replaced with PcdAcpiS3Enable in several OVMF libraries to avoid the
potential inconsistency.

v2:
  - Amend the description and address "HVM Direct Kernel Boot"
  - Add the comment for the conditional test of QemuFwCfgS3Enabled()
  - Remove unused QemuFwCfgLib
  - Update my email address

Gary Lin (5):
  OvmfPkg/OvmfXen: set PcdAcpiS3Enable at initialization
  OvmfPkg/OvmfXen: add QemuKernelLoaderFsDxe
  OvmfPkg/LockBoxLib: use PcdAcpiS3Enable to detect S3 support
  OvmfPkg/PlatformBootManagerLib: use PcdAcpiS3Enable to detect S3
    support
  OvmfPkg/SmmControl2Dxe: use PcdAcpiS3Enable to detect S3 support
