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 ().

resume.
The content of the LockBox will be a DevicePath structure that contains
zero or more DevicePath instances. Each instance denotes a storage device
that needs to get initialized during the S3 resume.
The producers of the content of this LockBox will be drivers like
OpalPassword DXE driver. This kind of drivers requires some specific
storage devices to be initialized during the PEI phase of in S3 resume.
(For the OpalPassword case, it requires the managing devices to be
automatically unlocked during the S3 resume).
The attribute of the LockBox should be set to
LOCK_BOX_ATTRIBUTE_RESTORE_IN_S3_ONLY.
The consumers of the content of this LockBox will be PEI storage device
controller/bus drivers (e.g. NvmExpressPei) during S3 resume. This kind of
drivers can use the DevicePath instances stored in the LockBox to get a
list of devices that need to get initialized. In such way, an on-demand

What to do:
1. Merge from Auth Variable driver in SecurityPkg to Variable drive in
MdeModulePkg. Then the merged Variable driver in MdeModulePkg will
link to AuthVariableLib and TpmMeasurementLib.
AuthVariableLibNull and TpmMeasurementLibNull in MdeModulePkg
could be used for non auth variable support.
AuthVariableLib and DxeTpmMeasurementLib in SecurityPkg
may be used for auth variable support.
Why to do:
1. Remove code duplication and reduce maintenance effort.
After auth variable service separated from Auth Variable driver in SecurityPkg
to AuthVariableLib. The remaining code logic of Auth Variable driver in SecurityPkg
will be almost same with Variable driver in MdeModulePkg. Now it is to
merge them.
