v3:
- Drop the following patches, applied from v2:
[PATCH v2 04/32] OvmfPkg: PlatformPei: simplify memory range
expressions in MemDetect()
[PATCH v2 05/32] OvmfPkg: PlatformPei: reuse PublishPeiMemory() in
MemDetect()
[PATCH v2 24/32] OvmfPkg: QemuFwCfgLib: drop bogus dependency on
UefiBootServicesTableLib
- Implement OVMF-specific LockBoxLib (on top of EmuNvramLib), rather
than emulating SMRAM for edk2's SMM-based LockBoxLib. Consequently,
don't pull in the SMM core and dependent SMM drivers, but rebase the
S3 machinery to the new LockBoxLib.
- Replace the following patches:
[PATCH v2 11/32] OvmfPkg: S3 Suspend: introduce EmuSmmDxe for exposing
SMRAM
[PATCH v2 12/32] OvmfPkg: S3 Suspend: pull in DXE driver for
EFI_SMM_COMMUNICATION_PROTOCOL
[PATCH v2 13/32] OvmfPkg: S3 Suspend: pull in SmmLockBox driver
[PATCH v2 14/32] OvmfPkg: S3 Suspend: use SMM instances for LockBoxLib
library class
with
[PATCH v3 09/24] OvmfPkg: implement LockBoxLib
- Drop
[PATCH v2 19/32] OvmfPkg: S3 Suspend: introduce DiscloseSmstSmm driver
- Drop
[PATCH v2 20/32] OvmfPkg: S3 Resume: introduce EmuSmmPei for exposing
SMRAM in PEI
and reimplement a small part of it with the new
[PATCH v3 14/24] OvmfPkg: S3 Resume: fake LockBox protocol for
BootScriptExecutorDxe
- Drop
[PATCH v2 30/32] OvmfPkg: AcpiS3SaveDxe: depend on SmmLockBox
explicitly
and reimplement a part of it inside
[PATCH v3 11/24] OvmfPkg: S3 Suspend: save ACPI context
- Changes in preserved patches:
[PATCH v3 01/24] OvmfPkg: PlatformPei: document ranges to be reserved
manually
- Range from 0x01400000 to 0x01500000 covers LockBox, not SMRAM.
- Updated PCD names accordingly.
- Range from 0x01500000 to 0x01501000, covering SMST pointer in v2, is
removed.
- Post-resume PEI permanent memory, starting at 0x01501000 in v2, is
shifted down to 0x01500000.
[PATCH v3 02/24] OvmfPkg: introduce EmuNvramLib
- EmuNvramSmram*() -> EmuNvramLockBox*()
- EmuNvramSmstPtr*() -> dropped
- same for PCDs
[PATCH v3 11/24] OvmfPkg: S3 Suspend: save ACPI context
- Update LockBoxLib dependency tree in commit message.
- Since the new LockBoxLib doesn't depend on a separate LockBox
driver, OVMF's AcpiS3SaveDxe can't use a Depex to check for a
working LockBox. Look at the NVRAM LockBox size explicitly in the
InstallAcpiS3Save() function instead.
- DSC files: no need to resolve LockBoxLib for DXE_DRIVER modules, the
global resolution added in "[PATCH v3 09/24] OvmfPkg: implement
LockBoxLib" works.
[PATCH v3 12/24] OvmfPkg: S3 Suspend: enable creation/saving of an S3
Boot Script
- Update PiDxeS3BootScriptLib dependencies in the commit message.
- Replace SMRAM language with EfiACPIMemoryNVS/LockBox in the commit
message.
[PATCH v3 13/24] OvmfPkg: S3 Suspend: save boot script after ACPI
context
- Update commit message to reflect that our LockBox implementation is
actually not locked down by installation of
EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL. This is harmless.
[PATCH v3 15/24] OvmfPkg: S3 Resume: pull in BootScriptExecutorDxe
- Update BootScriptExecutorDxe and PiDxeS3BootScriptLib dependencies
in commit message (SMM vs. new LockBoxLib).
[PATCH v3 16/24] OvmfPkg: S3 Resume: pull in PEIM orchestrating S3
- Update S3Resume2Pei dependencies in commit message (SMM vs. new
LockBoxLib).
- No need to resolve LockBoxLib specifically for PEIMs.
[PATCH v3 17/24] OvmfPkg: PlatformPei: detect S3 Resume in CMOS and
- update commit message: LockBox is not in SMRAM
[PATCH v3 19/24] OvmfPkg: QemuFwCfgLib: introduce
InternalQemuFwCfgIsAvailable()
- add Jordan's R-b to commit message
[PATCH v3 20/24] OvmfPkg: QemuFwCfgLib: extract stateful
implementation
- rename "StatefulImpl.c" to "QemuFwCfgLibPeiDxe.c"
- add Jordan's R-b to commit message
[PATCH v3 21/24] OvmfPkg: QemuFwCfgLib: implement for SEC
- rename "StatelessImpl.c" to "QemuFwCfgLibSec.c"
- add comment suggested by Jordan to InternalQemuFwCfgIsAvailable()
- add Jordan's R-b to commit message
[PATCH v3 23/24] OvmfPkg: turn off NVRAM emulation when S3 is
explicitly disabled
- update commit message to reflect new (smaller) NVRAM range
0x01400000..0x03500000, ie. without SmstPtr page in the middle
- update explanation in commit message wrt .how turning off NVRAM
disables AcpiS3SaveDxe and BootScriptExecutorDxe thru LockBox
- drop mentions of SMM in commit message
- adapt code to new NVRAM layout
