GraphicsConsoleDxe (a UEFI_DRIVER under MdeModulePkg/Universal/Console)
determines the preferred video resolution from the dynamic PCDs
- gEfiMdeModulePkgTokenSpaceGuid.PcdVideoHorizontalResolution
- gEfiMdeModulePkgTokenSpaceGuid.PcdVideoVerticalResolution
In one of the next patches, we'd like to change these PCDs. In order for
GraphicsConsoleDxe to retrieve the new values dynamically,
- it must be linked with the non-null instance of PcdLib,
- OvmfPkg must provide dynamic defaults.
We keep MdeModulePkg's 800x600 default resolution. (The UEFI specification
requires video drivers to support 800x600.)

The Boot#### variables that have become unreferenced in the new BootOrder
variable won't ever be automatically reused for booting. They are
"unreachable" resources that take up room in the variable store. Make an
effort to remove them.
This should plug the leak which, given sufficient reboots, exhausts the
variable store with stale Boot#### variables and renders the VM
unbootable.

When PI can distinguish the "full config" boot mode from "assume no
changes", then the following BDS logic is correct:
if BootMode == BOOT_WITH_FULL_CONFIGURATION:
//
// connect all devices
// create & append each default boot option that's missing
//
BdsLibConnectAll
BdsLibEnumerateAllBootOption
else if BootMode == BOOT_ASSUMING_NO_CONFIGURATION_CHANGES:
//
// just stick with current BootOrder and the Boot#### variables
// referenced by it
//
In theory, the first branch is intended to run infrequently, and the
"assume no changes" branch should run most of the time.
However, some platforms can't tell these two boot modes apart. The
following substitute had been introduced:
//
// Technically, always assume "full config", but the BootMode HOB is
// actually meaningless wrt. to "full config" or "assume no changes".
//
ASSERT (BootMode == BOOT_WITH_FULL_CONFIGURATION);
//
// Key off the existence of BootOrder. Try to prepare an in-memory list
// of boot options, based on BootOrder and the referenced Boot####
// variables.
//
Status = BdsLibBuildOptionFromVar()
//
// If that succeeded, we'll treat it as "assume no changes". If it
// failed (*only* if it failed), we'll build default boot options,
// calling it "full config":
//
if EFI_ERROR(Status):
BdsLibConnectAll()
BdsLibEnumerateAllBootOption(BootOptionList)
What we have now in OVMF is a mixture of the hack, and the behavior that's
theoretically correct for "full config":
- We assert "full config" -- this is OK.
- We call "connect all" and "enumerate all" deliberately -- this is OK
too. It matches "full config" which we assert.
- However, we also have the hack in place, which had been meant as an
alternative.
In order to clean this up, we either need to restore the hack to its
original form (ie. comment out the unconditional calls again), or we ought
to remove the hack altogether.
The unconditional "connect all" + "enumerate all" calls are the correct
approach for OVMF, because we want, in fact, to start with "full config".
The QEMU boot order specification and the set of emulated devices might
change "out of band", which excludes "assume no changes".
In other words, removing the hack corresponds to the "real production"
case that the comment hints at.
Because SetBootOrderFromQemu() may change the BootOrder NvVar, we must
preserve the BdsLibBuildOptionFromVar() function call, in order to
refresh the in-memory list with the new boot priorities.
(The last step of BdsLibEnumerateAllBootOption() is such a call too.)

This driver (from
"MdeModulePkg/Universal/Acpi/BootScriptExecutorDxe/BootScriptExecutorDxe.inf")
is first loaded normally during DXE. When the
EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL is installed by any DXE driver (purely
as a form of notification), the driver reloads itself to reserved memory.
During S3 Resume / PEI, the driver image is executed from there. In order
to access the boot script saved during S3 Suspend, LockBox access is
needed.
The boot script is transferred internal to PiDxeS3BootScriptLib:
Both S3SaveStateDxe and BootScriptExecutorDxe are statically linked
against PiDxeS3BootScriptLib. Whichever is loaded first (during normal
boot, in the DXE phase), allocates the root storage for the script. The
address is then passed between the PiDxeS3BootScriptLib instances living
in the two separate drivers thru the dynamic
PcdS3BootScriptTablePrivateDataPtr PCD.

BootScriptExecutorDxe

BootScriptExecutorDxe, to be pulled in in the next patch, was written with
the SMM implementation of LockBox in mind. That implementation is split in
the following three parts:
- client side (DXE/PEI) library,
- SMM driver producing gEfiLockBoxProtocolGuid,
- driver side (SMM) library.
BootScriptExecutorDxe includes the client side LockBoxLib. So that the
library can communicate with the SMM LockBox driver, BootScriptExecutorDxe
has a Depex on gEfiLockBoxProtocolGuid, normally installed by the SMM
LockBox driver. This is actually not a hard dependency, it just ensures
correct load order between BootScriptExecutorDxe and
MdeModulePkg/Universal/LockBox/SmmLockBox.
The (client side) LockBox library instance in OVMF doesn't depend on a
separate driver that produces gEfiLockBoxProtocolGuid. Nothing produces
that GUID right now in OVMF. This prevents BootScriptExecutorDxe from
loading.
Install gEfiLockBoxProtocolGuid in our only S3-specific, custom DXE
driver, in order to enable loading of BootScriptExecutorDxe.

The trigger to actually save the boot script is the installation of
EFI_DXE_SMM_READY_TO_LOCK_PROTOCOL, to be performed by any DXE driver.
Installation of the protocol also locks down SMM (as its name indicates)
and (in theory) prevents further LockBox access.
We cannot install this protocol before BdsLibBootViaBootOption() is called
(eg. in OVMF's PlatformBdsPolicyBehavior()), because
BdsLibBootViaBootOption() calls EFI_ACPI_S3_SAVE_PROTOCOL.S3Save(), which
needs LockBox access.
We also can't install the protocol after BdsLibBootViaBootOption()
returns, simply because control is never returned to us.
Therefore modify our EFI_ACPI_S3_SAVE_PROTOCOL implementation so that the
boot script is prepared and installed internally to S3Save().
(The boot script must contain at least one opcode, otherwise
S3BootScriptLib runs into an assertion failure. We add a harmless (no-op)
"information" opcode.)

"MdeModulePkg/Universal/Acpi/S3SaveStateDxe/S3SaveStateDxe.inf" produces
the EFI_S3_SAVE_STATE_PROTOCOL which allows creation and saving of an S3
Boot Script, to be replayed in PEI during S3 Resume. The script contains
opcodes and opcode arguments to configure CPU, PCI and IO resources.
S3SaveStateDxe relies on the S3BootScriptLib library. The Null
implementation is not useful for actually saving the boot script, we need
the PiDxeS3BootScriptLib instance.
The PiDxeS3BootScriptLib library instance depends on LockBoxLib,
implemented for OVMF in one of the previous patches.
PiDxeS3BootScriptLib also depends on SmbusLib. For now we opt for the Null
instance of the latter. It means that SMBus commands in the boot script
will have no effect when interpreted during S3 Resume. This should be fine
for OvmfPkg and QEMU.

"IntelFrameworkModulePkg/Universal/Acpi/AcpiS3SaveDxe/AcpiS3SaveDxe.inf"
currently specifies a DepEx on gEfiMpServiceProtocolGuid (MP Services).
The justification is the following code sequence:
InstallAcpiS3Save()
if PcdFrameworkCompatibilitySupport is set:
InstallAcpiS3SaveThunk()
if EFI_MP_SERVICES_PROTOCOL is available:
GetVariable(ACPI_GLOBAL_VARIABLE)
In English, the AcpiS3SaveDxe driver insists on the presence of MP
Services *unconditionally* because,
- if PcdFrameworkCompatibilitySupport is set (the default is false),
- and MP Services are available (which is constant true under the above
condition),
then the AcpiS3SaveDxe driver would like to get the ACPI_GLOBAL_VARIABLE
variable from the MP Services driver, rather than setting it itself.
The DepEx prevents AcpiS3SaveDxe from loading under OvmfPkg, since we
provide no MP Services implementation. This is particularly broken since
the default PcdFrameworkCompatibilitySupport value is FALSE, making the
entire code that would look at EFI_MP_SERVICES_PROTOCOL dead.
Copy AcpiS3SaveDxe to OvmfPkg, substitute PcdFrameworkCompatibilitySupport
with constant FALSE, and remove all code that becomes dead, including the
DepEx.

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.
