Michael Kubacki 6fe77f347e MdeModulePkg/Variable: Fix volatile variable RT cache update logic
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2333

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.

Fixes: aab3b9b9a1

Jiewen Yao 995d8b8568 MdeModulePkg/Pci: Add DeviceSecurity support.
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2303

Whenever a PCI device is discovered, PCI bus calls the
EDKII_DEVICE_SECURITY_PROTOCOL to authenticate it.
If the function returns success, the PCI bus allocates
the resource and installs the PCI_IO for the device.
If the function returns fail, the PCI bus skips the device.

It is similar to EFI_SECURITY_ARCH_PROTOCOL, which
is used to verify an EFI image.

When a boot loader examines the memory map, it can see that location 0
is available memory. If it chooses to use that memory, and
PcdNullPointerDetectionPropertyMask is enabled, use of memory in page 0
will cause an exception. This does occur when running the memtest86

Leaving page 0 available is for legacy support purpose. Since we have
deprecated the support of legacy, the solution is just reserving it so
that it cannot be allocated for other uses.

Michael Kubacki 6f9838f32f MdeModulePkg/Variable: Add RT GetNextVariableName() cache support
https://bugzilla.tianocore.org/show_bug.cgi?id=2220

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
is set to TRUE (default value).

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.

Michael Kubacki aab3b9b9a1 MdeModulePkg/Variable: Add RT GetVariable() cache support
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 ().

Michael Kubacki 1747ab6c1c MdeModulePkg VariableInfo: Always consider RT DXE and SMM stats
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2220

The current VariableInfo application only checks for variable
statistics from SMM if the variable information entries are
not present in the UEFI System Configuration table as published
by the DXE UEFI variable driver (VariableRuntimeDxe).

This change first checks for variable information entries in the
UEFI System Configuration but always checks for entries in SMM
as well. If the SMM variable driver is not present, an instance of
EFI_SMM_VARIABLE_PROTOCOL will not be found and the search for
SMM variable statistics will be aborted (an SW SMI to get variable
statistics will not be triggered).

In the case variable statistics are provided by both a Runtime DXE
driver (e.g. VariableSmmRuntimeDxe) and a SMM driver (VariableSmm),
this change will clearly identify statistics from each respective
driver.

Sunny Wang b15646484e MdeModulePkg/BdsDxe: Fix PlatformRecovery issue
For now, PlatformRecovery doesn't work if OsIndications variable
doesn't exist, which is wrong.
According to the UEFI specification section 3.4.1 and 3.4.2, if
processing of BootOrder does not result in success, the OsRecovery
and PlatformRecovery options should still be processed regardless of
the existence of the OsIndications variable.
Therefore, update the code to check PcdPlatformRecoverySupport instead
of the value of OsIndications variable (PlatformRecovery) to fix
this issue.

This patch also ensures that, if PcdPlatformBootTimeOut is 0xFFFF we don't

Laszlo Ersek 0bee7dbd2b MdeModulePkg/PlatformVarCleanupLib: fix HiiConstructConfigHdr() call
The HiiConstructConfigHdr() function takes the "DriverHandle" parameter in
order to fetch the device path from it, and then turn the device path into
PATH routing information.

The HiiConstructConfigHdr() function is called from
VariableCleanupHiiExtractConfig(), which is only installed when "Type" is
"VarCleanupManually" in PlatformVarCleanup().

In that case, we create "Private->DriverHandle" as a new handle, and
install "mVarCleanupHiiVendorDevicePath" on it. Then we pass
"Private->DriverHandle" to HiiAddPackages(), which consumes the device
path for routing purposes.

It follows that the "DriverHandle" argument passed to
HiiConstructConfigHdr() should be the same driver handle, for matching
routing.

Currently we pass "Private->HiiHandle", which is clearly a typo, because
it is the return value of HiiAddPackages(), and stands for the published
HII package list.

Therefore this patch addresses an actual bug.

The typo has not been flagged by compilers because the UEFI spec
regrettably defines both EFI_HANDLE and EFI_HII_HANDLE as (VOID*).
