Commit aab3b9b9a1 ("MdeModulePkg/Variable: Add RT GetVariable() cache
support", 2019-11-05) added "VariableParsing.h" to
"VariableSmmRuntimeDxe.inf".
"VariableParsing.h" includes "Variable.h", so the "build" utility is right
to warn us that "Variable.h" should be listed in [Sources] too.

During a SetVariable () invocation, UpdateVariable () is called.
UpdateVariable () contains logic to determine whether a volatile or
non-volatile UEFI variable was set so the corresponding runtime
cache can be updated to reflect the change. The current logic simply
evaluates Variable->Volatile to determine which runtime cache should
be updated.
The problem is Variable->Volatile does not always reflect whether a
volatile variable is being set. Variable->Volatile is set to TRUE
only in the case a pre-existing variable is found in the volatile
variable store. Therefore, the value is FALSE when a new volatile
variable is written.
This change updates the logic to take this into account. If a new
variable is written successfully, the Attributes will accurately
reflect whether the variable is non-volatile. If a pre-existing
variable is modified, the Volatile field will reflect the type of
variable (Attributes are not reliable; e.g. 0x0 indicates deletion).
* Observable symptom: A volatile variable that was set successfully
might return EFI_NOT_FOUND when the variable should be found.
* The issue is a regression introduced to the variable services only
when the variable runtime cache is enabled by the following PCD
being set to TRUE:
gEfiMdeModulePkgTokenSpaceGuid.PcdEnableVariableRuntimeCache
* The issue was implemented in commit aab3b9b9a1 but the PCD was not
set to TRUE by default enabling the issue until commit e07b7d024a.

This change implements the Runtime Service GetNextVariableName()
using the runtime cache in VariableSmmRuntimeDxe. Runtime Service
calls to GetNextVariableName() will no longer trigger a SW SMI
when gEfiMdeModulePkgTokenSpaceGuid.PcdEnableVariableRuntimeCache

Overall system performance and stability will be improved by
eliminating an SMI for these calls as they typically result in a
relatively large number of invocations to retrieve all variable
names in all variable stores present.

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2220
This change reduces SMIs for GetVariable () by maintaining a
UEFI variable cache in Runtime DXE in addition to the pre-
existing cache in SMRAM. When the Runtime Service GetVariable()
is invoked, a Runtime DXE cache is used instead of triggering an
SMI to VariableSmm. This can improve overall system performance
by servicing variable read requests without rendezvousing all
cores into SMM.
The runtime cache can be disabled with by setting the FeaturePCD
gEfiMdeModulePkgTokenSpaceGuid.PcdEnableVariableRuntimeCache
to FALSE. If the PCD is set to FALSE, the runtime cache will not be
used and an SMI will be triggered for Runtime Service
GetVariable () and GetNextVariableName () invocations.
The following are important points regarding the behavior of the
variable drivers when the variable runtime cache is enabled.
1. All of the non-volatile storage contents are loaded into the
cache upon driver load. This one time load operation from storage
is preferred as opposed to building the cache on demand. An on-
demand cache would require a fallback SMI to load data into the
cache as variables are requested.
2. SetVariable () requests will continue to always trigger an SMI.
This occurs regardless of whether the variable is volatile or
non-volatile.
3. Both volatile and non-volatile variables are cached in a runtime
buffer. As is the case in the current EDK II variable driver, they
continue to be cached in separate buffers.
4. The cache in Runtime DXE and SMM are intended to be exact copies
of one another. All SMM variable accesses only return data from the
SMM cache. The runtime caches are only updated after the variable I/O
operation is successful in SMM. The runtime caches are only updated
from SMM.
5. Synchronization mechanisms are in place to ensure the runtime cache
content integrity with the SMM cache. These may result in updates to
runtime cache that are the same in content but different in offset and
size from updates to the SMM cache.
When using SMM variables with runtime cache enabled, two caches will now
be present.
1. "Runtime Cache" - Maintained in VariableSmmRuntimeDxe. Used to service
Runtime Services GetVariable () and GetNextVariableName () callers.
2. "SMM Cache" - Maintained in VariableSmm to service SMM GetVariable ()
and GetNextVariableName () callers.
a. This cache is retained so SMM modules do not operate on data outside
SMRAM.
Because a race condition can occur if an SMI occurs during the execution
of runtime code reading from the runtime cache, a runtime cache read lock
is introduced that explicitly moves pending updates from SMM to the runtime
cache if an SMM update occurs while the runtime cache is locked. Note that
it is not expected a Runtime services call will interrupt SMM processing
since all CPU cores rendezvous in SMM.
It is possible to view UEFI variable read and write statistics by setting
the gEfiMdeModulePkgTokenSpaceGuid.PcdVariableCollectStatistics FeaturePcd
to TRUE and using the VariableInfo UEFI application in MdeModulePkg to dump
variable statistics to the console. By doing so, a user can view the number
of GetVariable () hits from the Runtime DXE variable driver (Runtime Cache
hits) and the SMM variable driver (SMM Cache hits). SMM Cache hits for
GetVariable () will occur when SMM modules invoke GetVariable ().

The patch is to merge multiple FMP instances into single ESRT entry
when they have the same GUID.
The policy to LastAttemptStatus/LastAttemptVersion of ESRT entry is:
If all the LastAttemptStatus are LAST_ATTEMPT_STATUS_SUCCESS, then
LastAttemptVersion should be the smallest of LastAttemptVersion. If
any of the LastAttemptStatus is not LAST_ATTEMPT_STATUS_SUCCESS,
then the LastAttemptVersion/LastAttemptStatus should be the values
of the first FMP instance whose LastAttemptStatus is not
LAST_ATTEMPT_STATUS_SUCCESS.
To detect possible duplicated GUID/HardwareInstance, a table of
GUID/HardwareInstance pairs from all the EFI_FIRMWARE_IMAGE_DESCRIPTORs
from all FMP instances is built. If a duplicate is found, then generate
a DEBUG_ERROR message, generate an ASSERT(), and ignore the duplicate
EFI_FIRMWARE_IMAGE_DESCRIPTOR.
Add an internal worker function called FmpGetFirmwareImageDescriptor()
that retrieves the list of EFI_FIRMWARE_IMAGE_DESCRIPTORs from a single
FMP instance and returns the descriptors in an allocated buffer. This
function is used to get the descriptors used to build the table of
unique GUID/HardwareInstance pairs. It is then used again to generate
the ESRT Table from all the EFI_FIRMWARE_IMAGE_DESCRIPTORs from all the
FMP instances. 2 passes are performed so the total number of
descriptors is known. This allows the correct sized buffers to always
be allocated.

Use the PcdPlatformRecoverySupport to control the function
of platform recovery in BDS.
First, set the variable's ("OsIndicationsSupported")
EFI_OS_INDICATIONS_START_PLATFORM_RECOVERY bit base on the pcd.
It would affect the variable "OsIndications".
While the platform does not support the platform recovery,
it is inappropriate to set a PlatformRecovery#### variable. So
skip setting the variable. But it should remain the behavior of
booting from a default file path (such as \EFI\BOOT\BOOTX64.EFI)
to be compatible with the previous version UEFI spec.
Add memory check before build platform default boot option. If
fail to allocate memory for the defualt boot file path, put the
system into dead loop to indicate it is unable to boot.
