OvmfPkg: implement LockBoxLib The S3 suspend/resume infrastructure depends on the LockBox library class. The edk2 tree currently contains Null and SMM instances. The Null instance is useless, and the SMM instance would require SMM emulation by including the SMM core and adding several new drivers, which is deemed too complex. Hence add a simple LockBoxLib instance for OVMF. jordan.l.justen@intel.com: * use PCDs instead of EmuNvramLib - clear memory in PlatformPei on non S3 boots * allocate NVS memory and store a pointer to that memory - reduces memory use at fixed locations Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Laszlo Ersek <lersek@redhat.com> Reviewed-by: Jordan Justen <jordan.l.justen@intel.com> Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Jordan Justen <jordan.l.justen@intel.com> Reviewed-by: Laszlo Ersek <lersek@redhat.com> git-svn-id: https://svn.code.sf.net/p/edk2/code/trunk/edk2@15301 6f19259b-4bc3-4df7-8a09-765794883524

OvmfPkg: Install LockBox protocol in constructor of LockBoxDxeLib Currently, the LockBox protocol is installed in entrypoint of OVMF AcpiS3SaveDxe. We can let the first driver run with LockBoxDxeLib linked to have its library constructor to install LockBox protocol on the ImageHandle. As other drivers may have gEfiLockBoxProtocolGuid dependency, the first driver should run before them. The later patches to retire AcpiS3SaveDxe for OVMF depends on this patch.

QemuFwCfgLib
ArmVirtPkg, OvmfPkg: retire QemuFwCfgS3Enabled() from QemuFwCfgLib At this point we're ready to retire QemuFwCfgS3Enabled() from the QemuFwCfgLib class, together with its implementations in: - ArmVirtPkg/Library/QemuFwCfgLib/QemuFwCfgLib.c - OvmfPkg/Library/QemuFwCfgLib/QemuFwCfgLib.c Extend all modules that call the function with a new QemuFwCfgS3Lib class dependency. Thanks to the previously added library class, instances, and class resolutions, we can do this switch now as tightly as possible.
