Awiral Shrivastava 5b08df03f8 MdeModulePkg: Optimize PEI Core Migration Algorithm
REF : https://bugzilla.tianocore.org/show_bug.cgi?id=4750

Migrate the FV that doesn't contain the currently executing PEI Core
when permanent memory is initialized but PEI Core is still potentially
running from faster memory (Tepmorary RAM). This may reduce the time
required to migrate FVs to permanent memory. The FV containing PEI
Core is migrated after the PEI Core reentry when it is executed from
permanent memory.

This may or may not improve performance depending on the behavior of
temporary RAM and the actual performance changes must be measured with
the feature enabled and disabled.

This migration algorithm is only used for FVs specified in the
gEdkiiMigrationInfoGuid HOB and built with flag
FLAGS_FV_MIGRATE_BEFORE_PEI_CORE_REENTRY.

Dun Tan 43e2395c1b MdeModulePkg: fix issue caused by uninitialized variable
This patch is to fix issue caused by uninitialized local
variable in Pei/Variable.c.

In the fucntion CalculateHobVariableCacheSize(), the local
variable VARIABLE_STORE_INFO StoreInfo is used without
initialization. When the uninitialized variable is passed
to CalculateAuthVarStorageSize() and GetNextVariablePtr(),
the field StoreInfo->FtwLastWriteData might be a uninitialized
non-zero value. Then the code execution will access the
invalid address StoreInfo->FtwLastWriteData->TargetAddress.
This might cause issue.

So in this commit, the local variable VARIABLE_STORE_INFO
StoreInfo is initialized by a ZeroMem() before use.

Kun Qin cee9d1b16b MdeModulePkg: DxeCore: Fix Use-After-Free guard causing page fault
REF:https://bugzilla.tianocore.org/show_bug.cgi?id=2411

With Use-After-Free heap guard feature enabled, the DxeCore would blindly
attempt to "level-up" when the `GuardAllFreedPages` inspect a non-max
level table entry from the last loop. This could cause the next round of
inspection to dereference a potentially null pointer and as such causing
a page fault.

This change adds a null pointer check to prevent such case from happening.

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4653

In DxeIplFindDxeCore function, there exists different behavior between
Debug and Release built BIOS. This change is used to unify both of
the code flow and fix the potential overflow of "Instance" variable.

In this change,
  [1] Move the ASSERT_EFI_ERROR (Status) in failure to find DxeCore

  [2] Break the while-loop when not found required DxeCore.
      This would make the Instance variable not overflow in while-loop.
  [3] Add the CpuDeadLoop () in the end of the function and do not
      return since DxeCore is mandatory for the following booting
      to hand-off the PEI phase to DXE phase.
  [4] In case of the CpuDeadLoop () is de-assert by debugger,

Britton Chesley ed07a2bb11 MdeModulePkg/UsbBusDxe: USB issue fix when the port reset
BZ #4456

Fixed a bug which led to an ASSERT due to the USB device
context being maintained after a port reset, but the
underlying XHCI context was uninitialized. Specifically,
Xhc->UsbDevContext is freed after a reset and only
re-allocates the default [0] enpoint transfer ring.
In order to avoid a memory leak, device enumeration is
performed after freeing the necessary buffers. This
allocates the Xhc->UsbDevContext for all endpoints of
the USB device.

This patch fix a use-after-free issue where unregistering an
SMI handler could lead to the deletion of the SMI_HANDLER while it is
still in use by SmiManage(). The fix involves modifying
SmiHandlerUnRegister() to detect whether it is being called from
within the SmiManage() stack. If so, the removal of the SMI_HANDLER
is deferred until SmiManage() has finished executing.
Additionally, due to the possibility of recursive SmiManage() calls,
the unregistration and subsequent removal of the SMI_HANDLER are
ensured to occur only after the outermost SmiManage() invocation has
completed.

Oliver Smith-Denny 1fb6462c67 MdeModulePkg: ImagePropertiesRecordLib: Use SectionAlignment for CodeSize
When an ImageRecord is stored by ImagePropertiesRecordLib, it reports the
CodeSegmentSize as the SizeOfRawData from the image. However, the image
as loaded into memory is aligned to the SectionAlignment, so
SizeOfRawData is under the actual size in memory. This is important,
because the memory attributes table uses these image records to create
its entries and it will report that the alignment of an image is
incorrect, even though the actual image is correct.

This was discovered on ARM64, which has a 64k runtime page granularity
alignment, which is backed by a 64k section alignment for
DXE_RUNTIME_DRIVERs. The runtime code and data was correctly being
loaded into memory, however the memory attribute table was incorrectly
reporting misaligned ranges to the OS, causing attributes to be
ignored for these sections for OSes using greater than 4k pages.

This patch correctly aligns the CodeSegmentSize to the SectionAlignment
and the corresponding memory attribute table entries are now correctly
aligned and pointing to the right places in memory.

Oliver Smith-Denny e7486b5064 MdeModulePkg: DxeCore: Do Not Apply Guards to Unsupported Types
Currently, there are multiple issues when page or pool guards are
allocated for runtime memory regions that are aligned to
non-EFI_PAGE_SIZE alignments. Multiple other issues have been fixed for
these same systems (notably ARM64 which has a 64k runtime page
allocation granularity) recently. The heap guard system is only built to
support 4k guard pages and 4k alignment.

Today, the address returned to a caller of AllocatePages will not be
aligned correctly to the runtime page allocation granularity, because
the heap guard system does not take non-4k alignment requirements into
consideration.

However, even with this bug fixed, the Memory Allocation Table cannot be
produced and an OS with a larger than 4k page granularity will not have
aligned memory regions because the guard pages are reported as part of
the same memory allocation. So what would have been, on an ARM64 system,
a 64k runtime memory allocation is actually a 72k memory allocation as
tracked by the Page.c code because the guard pages are tracked as part
of the same allocation. This is a core function of the current heap
guard architecture.

This could also be fixed with rearchitecting the heap guard system to
respect alignment requirements and shift the guard pages inside of the
outer rounded allocation or by having guard pages be the runtime
granularity. Both of these approaches have issues. In the former case,
we break UEFI spec 2.10 section 2.3.6 for AARCH64, which states that
each 64k page for runtime memory regions may not have mixed memory
attributes, which pushing the guard pages inside would create. In the
latter case, an immense amount of memory is wasted to support such large
guard pages, and with pool guard many systems could not support an
additional 128k allocation for all runtime memory.

The simpler and safer solution is to disallow page and pool guards for
runtime memory allocations for systems that have a runtime granularity
greater than the EFI_PAGE_SIZE (4k). The usefulness of such guards is
limited, as OSes do not map guard pages today, so there is only boot
time protection of these ranges. This also prevents other bugs from
being exposed by using guards for regions that have a non-4k alignment
requirement, as again, multiple have cropped up because the heap guard
system was not built to support it.

This patch adds both a static assert to ensure that either the runtime
granularity is the EFI_PAGE_SIZE or that the PCD bits are not set to
enable heap guard for runtime memory regions. It also adds a check in
the page and pool allocation system to ensure that at runtime we are not
allocating a runtime region and attempt to guard it (the PCDs are close
to being removed in favor of dynamic heap guard configurations).

Li, Zhihao 371940932d MdeModulePkg/Core/Pei: Improve the copy performance
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4697

EvacuateTempRam function will copy the temporary memory context to the rebased
pages and the raw pages. Migrations of rebased PEIMs is from cache to memory,
while raw PEIMs is from memory to memory. So the migrations of raw PEIMs
is slower than rebased PEIMs. Experimental data indicates that changing the source
address of raw PEIMs migration will improve performance by 35%.

So running in 4-level paging mode with PcdUse5LevelPageTable=TRUE is

Michael Kubacki 33c81c25bb MdeModulePkg/TraceHubDebugSysTLib: Use wider type for loop comparisons
Resolves a new CodeQL error due to the value being incremented in the
loop being a narrower type than the variable it is being compared
against.

The variable is changed to a UINT32 type so it has the same width as
the type it is being compared against.

Issue explanation: In a loop condition, comparison of a value of a
narrow type with a value of a wide type may result in unexpected
behavior if the wider value is sufficiently large (or small). This
is because the narrower value may overflow. This can lead to an
infinite loop.

Michael D Kinney af6e0e728f MdeModulePkg/Core/Dxe: Set MemoryTypeInfo bin range from HOB
Provide an optional method for PEI to declare a specific address
range to use for the Memory Type Information bins. The current
algorithm uses heuristics that tends to place the Memory Type
Information bins in the same location, but memory configuration
changes across boots or algorithm changes across a firmware
updates could potentially change the Memory Type Information bin
location. If the bin locations move across an S4 save/resume
cycle, then the S4 resume may fail. Enabling this feature
increases the number of scenarios that an S4 resume operation
may succeed.

If the HOB List contains a Resource Descriptor HOB that
describes tested system memory and has an Owner GUID of
gEfiMemoryTypeInformationGuid, then use the address range
described by the Resource Descriptor HOB as the preferred
location of the Memory Type Information bins. If this HOB is
not detected, then the current behavior is preserved.

The HOB with an Owner GUID of gEfiMemoryTypeInformationGuid
is ignored for the following conditions:
* The HOB with an Owner GUID of gEfiMemoryTypeInformationGuid
  is smaller than the Memory Type Information bins.
* The HOB list contains more than one Resource Descriptor HOB
  with an owner GUID of gEfiMemoryTypeInformationGuid.
* The Resource Descriptor HOB with an Owner GUID of
  gEfiMemoryTypeInformationGuid is the same Resource Descriptor
  HOB that that describes the PHIT memory range.

Neal Gompa 8c1e9f9c6f MdeModulePkg/UefiBootManagerLib: Signal ReadyToBoot on platform recovery
Currently, the ReadyToBoot event is only signaled when a formal Boot
Manager option is executed (in BmBoot.c -> EfiBootManagerBoot ()).

However, the introduction of Platform Recovery in UEFI 2.5 makes it
necessary to signal ReadyToBoot when a Platform Recovery boot loader
runs because otherwise it may lead to the execution of a boot loader
that has similar requirements to a regular one that is not launched
as a Boot Manager option.

This is especially critical to ensuring that the graphical console is
actually usable during platform recovery, as some platforms do rely on
the ConsolePrefDxe driver, which only performs console initialization
after ReadyToBoot is triggered.

This patch fixes that behavior by calling EfiSignalEventReadyToBoot ()
in EfiBootManagerProcessLoadOption () when invoking platform recovery,
which is the function that sets up the platform recovery boot process.

The expected behavior has been clarified in the UEFI 2.10 specification
to explicitly indicate this behavior is required for correct operation.

This is a rebased version of the patch originally written by Pete Batard.

Nate DeSimone ff4c49a5ee MdeModulePkg/Bus: Fix XhciDxe Linker Issues
The DXE & MM standalone variant of AcpiTimerLib defines a global
named mPerformanceCounterFrequency. A global with an identical
name is also present in MdeModulePkg/Bus/Pci/XhciDxe/Xhci.c

Since XhciDxe has a dependency on TimerLib, this can cause link
errors due to the same symbol being defined twice if the platform
DSC chooses to use AcpiTimerLib as the TimerLib implementation for
any given platform.

To resolve this, I noted that some of the globals in Xhci.c are not
used outside of the Xhci.c compilation unit:

- mPerformanceCounterStartValue
- mPerformanceCounterEndValue
- mPerformanceCounterFrequency
- mPerformanceCounterValuesCached

I have changed the definition for all of these to static and added
an Xhci prefix. Since they are not used outside of the Xhci.c
compilation unit, there is no reason to have them exported as
globals.

   path.
2. Replace CoreLocateDevicePath with IsDevicePathInstalled in
   CoreInstallMultipleProtocolInterfaces.

This optimization could save several seconds in PCI enumeration on a
