Star Zeng c1acb0f9b8 MdeModulePkg FirmwarePerfPei: Remove SEC performance data getting code
Current SEC performance data getting code in FirmwarePerformancePei
may get wrong SEC performance data if FirmwarePerformancePei executes
after memory discovered.

And as SecCore has added SecPerformancePpiCallBack to get SEC performance
data and build HOB to convey the SEC performance data to DXE phase.

This patch is to remove the SEC performance data getting code in
FirmwarePerformancePei.

Ard Biesheuvel 09da110819 MdeModulePkg/BootGraphicsResourceTableDxe: don't allocate below 4 GB
The BGRT table has an 8 byte field for the memory address of the image
data, and yet the driver explicitly allocates below 4 GB. This results
in an ASSERT() on systems that do not have any memory below 4 GB to begin
with.

Since neither the PI, the UEFI or the ACPI spec contain any mention of
why this data should reside below 4 GB, replace the allocation call
with an ordinary AllocatePages() call.

Ard Biesheuvel f859c6796f MdeModulePkg/AcpiTableDxe: consider version mask when removing tables
Invocations of EFI_ACPI_TABLE_PROTOCOL::UninstallAcpiTable() may
result in a crash when the value of PcdAcpiExposedTableVersions does
not include EFI_ACPI_TABLE_VERSION_1_0B.

The reason is that EFI_ACPI_TABLE_PROTOCOL::InstallAcpiTable() will
only populate the Rsdt1/Rsdt3 pointers when EFI_ACPI_TABLE_VERSION_1_0B
is set, whereas EFI_ACPI_TABLE_PROTOCOL::UninstallAcpiTable() will
invoke PublishTables with EFI_ACPI_TABLE_VERSION_1_0B alawys set,
resulting in a NULL pointer dereference of the Rsdt1/Rsdt3 pointers.

So take PcdAcpiExposedTableVersions into account for UninstallAcpiTable
as well.

Star Zeng 78807f6050 MdeModulePkg/AcpiTableDxe: Not make FADT.{DSDT,X_DSDT} mutual exclusion
198a46d768 improved the DSDT and X_DSDT
fields mutual exclusion by checking FADT revision, but that breaks
some OS that has assumption to only consume X_DSDT field even the
DSDT address is < 4G.

To have better compatibility, this patch is to update the code to not
make FADT.{DSDT,X_DSDT} mutual exclusion, but always set both DSDT and
X_DSDT fields in the FADT when the DSDT address is < 4G.

Laszlo Ersek 198a46d768 MdeModulePkg/AcpiTableDxe: improve FADT.{DSDT,X_DSDT} mutual exclusion
The ACPI specification, up to and including revision 5.1 Errata A, allows
the DSDT and X_DSDT fields to be both set in the FADT. (Obviously, this
only makes sense if the DSDT address is representable in 4 bytes.)

Starting with 5.1 Errata B, specifically for Mantis 1393
<https://mantis.uefi.org/mantis/view.php?id=1393>, the spec requires at
most one of DSDT and X_DSDT to be set to a nonzero value.

MdeModulePkg/AcpiTableDxe handles this mutual exclusion somewhat
inconsistently.

- If the caller of EFI_ACPI_TABLE_PROTOCOL.InstallAcpiTable() installs the
  tables in "DSDT, FADT" order, then we enforce the exclusion between the
  DSDT and X_DSDT fields:

  DSDT under 4GB  FADT.DSDT  FADT.X_DSDT    [VARIANT B]
  --------------  ---------  -----------
  yes             set        clear
  no              clear      set

  This behavior conforms to 5.1 Errata B. (And it's not required by
  earlier versions of the spec.)

- If the caller passes in the tables in "FADT, DSDT" relative order, then
  we do not enforce the exclusion:

  DSDT under 4GB  FADT.DSDT  FADT.X_DSDT    [VARIANT A]
  --------------  ---------  -----------
  yes             set        set
  no              clear      set

  This satisfies 5.1 Errata A and earlier, but breaks 5.1 Errata B and
  later.

Unify the handling of both relative orders. In particular, check the major
and minor version numbers in the FADT. If the FADT version is strictly
before 5.1, then implement [VARIANT A]. If the FADT version is equal to or
larger than 5.1, then implement [VARIANT B].

We make three observations:

- We can't check the FADT table version precisely against "5.1 Errata B";
  erratum levels are not captured in the table. We err in the safe
  direction, namely we enforce the exclusion for "5.1" and "5.1 Errata A".

- The same applies to "6.0" versus "6.0 Errata A". Because we cannot
  distinguish these two, we consider "6.0" to be "equal to or larger than
  5.1", and apply [VARIANT B], enforcing the exclusion.

- While a blanket [VARIANT B] would be simpler, there is a significant
  benefit to [VARIANT A], under the spec versions that permit it:
  compatibility with a wider range of OSPMs (typically, older ones).

  For example, Igor reported about a "DELL R430 system with rev4 FADT
  where DSDT and X_DSDT are pointing to the same address". Michael also
  reported about several systems that exhibit the same.

Hao Wu 16f6922709 MdeModulePkg: Refine casting expression result to bigger size
There are cases that the operands of an expression are all with rank less
than UINT64/INT64 and the result of the expression is explicitly cast to
UINT64/INT64 to fit the target size.

An example will be:
UINT32 a,b;
// a and b can be any unsigned int type with rank less than UINT64, like
// UINT8, UINT16, etc.
UINT64 c;
c = (UINT64) (a + b);

Some static code checkers may warn that the expression result might
overflow within the rank of "int" (integer promotions) and the result is
then cast to a bigger size.

The commit refines codes by the following rules:
1). When the expression is possible to overflow the range of unsigned int/
int:
c = (UINT64)a + b;

2). When the expression will not overflow within the rank of "int", remove
the explicit type casts:
c = a + b;

3). When the expression will be cast to pointer of possible greater size:
UINT32 a,b;
VOID *c;
c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b);

4). When one side of a comparison expression contains only operands with
rank less than UINT32:
UINT8 a;
UINT16 b;
UINTN c;
if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...}

For rule 4), if we remove the 'UINTN' type cast like:
if (a + b > c) {...}
The VS compiler will complain with warning C4018 (signed/unsigned
mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

Laszlo Ersek 387ccad8f6 MdeModulePkg: S3SaveStateDxe, SmmS3SaveState: save 64-bit LoopTimes
The BootScriptWriteMemPoll() helper function in both drivers does the
following:

- pop Delay from the variable argument list as UINT64, then truncate it to
  UINTN,

- divide Delay by 10, using DivU64x32Remainder(), then store the quotient
  in LoopTimes (also UINTN),

- pass LoopTimes to S3BootScriptSaveMemPoll() as last argument.

The truncation to UINTN is superfluous and wrong in this logic (not to
mention incompatible with the PI spec); it prevents callers from
specifying Delays longer than 0xFFFF_FFFF * 100ns (approximately 429
seconds == 7 minutes 9 seconds) on Ia32. In particular it prevents callers
from specifying an infinite timeout (for example, 0xFFFF_FFFF_FFFF_FFFF *
100ns, approximately 58494 years).

Change the type of Delay and LoopTimes to UINT64. Keep the same logic,
just remove the truncations. The resultant LoopTimes values can be safely
passed to S3BootScriptSaveMemPoll() thanks to the previous patch.

The S3Ready() functional code in AcpiS3SaveDxe of IntelFrameworkModulePkg
is to do ACPI S3 Context save. In fact, that is not really related to
Intel framework ACPI S3 protocol.

IntelFrameworkModulePkg will be deprecated step by step, so move the
functional code to MdeModulePkg and S3SaveStateDxe is a good place.
The ACPI global variable related code is leaved as is in IntelFrameworkModulePkg
AcpiS3SaveDxe for compatibility.
PcdS3BootScriptStackSize is also moved from IntelFrameworkModulePkg.

The functional code need to get ACPI FACS table and consume LockBoxLib,
so need to be before DxeSmmReadyToLock that will shut down SMM lock box
interface, EndOfDxe is a good point (OVMF AcpiS3SaveDxe has the reference
implementation).

can just move it and merge the two conditional blocks together.

Ard Biesheuvel f9bbb8d9c3 MdeModulePkg: AcpiTableDxe: make 4 GB table allocation limit optional
AARCH64 systems never require compatibility with legacy ACPI OSes, and
may not have any 32-bit addressable system RAM. To support ACPI on these
systems, we need to be able to relax the 4 GB allocation restriction.

So add a PCD PcdAcpiExposedTableVersions containing a bitmask describing
which ACPI versions are targeted, and wire it up it up to the memory
allocation calls in AcpiTableDxe/AcpiTableProtocol.c. I.e., if ACPI v1.0b
is not among the supported versions, the memory allocations are not limited
to 4 GB, and only table types that carry 64-bit addresses are emitted.

Note that this will inhibit the publishing of any tables that carry only
32-bit addresses, i.e., RSDPv1, RSDTv1 and RSDTv3.

Star Zeng c6368abcf0 MdeModulePkg BootScriptExecutorDxe: Reduce reserved memory consumption
We are going to reduce reserved memory consumption by page table buffer,
then OS can have more available memory to use.
Take PhysicalAddressBits = 48 and 2MB page granularity as example,
1:1 Virtual to Physical identity mapping page table buffer needs to be
((512 + 1) * 512 + 1) * 4096 = 1075843072 bytes = 0x40201000 bytes.

Current BootScriptExecutorDxe handles > 4G request by page fault because
S3ResumePeim only builds 4G page table when long mode waking vector is
not needed, but BootScriptExecutorDxe still assume the page table buffer for
page table is at 1:1 Virtual to Physical identity mapping.

To reduce reserved memory consumption, the code is updated to only use
8 extra pages to handles > 4G request by page fault.
Another, when both BIOS and OS wants long mode waking vector,
S3ResumePei should have established 1:1 Virtual to Physical identity mapping
page table for ACPI spec requirement, so no need to hook page fault handler.

Star Zeng 01267e224b MdeModulePkg AcpiTableDxe: Install config table at ACPI data change
UEFI spec has clear description below:

Configuration Table Groups
The GUID for a configuration table also defines a corresponding event group GUID with the same value.
If the data represented by a configuration table is changed,
InstallConfigurationTable() should be called.
When InstallConfigurationTable() is called, the corresponding event is signaled.
When this event is signaled,
any components that cache information from the configuration table can optionally update their cached state.
For example, EFI_ACPI_TABLE_GUID defines a configuration table for ACPI data.
When ACPI data is changed, InstallConfigurationTable() is called.
During the execution of InstallConfigurationTable(),
a corresponding event group with EFI_ACPI_TABLE_GUID is signaled,
allowing an application to invalidate any cached ACPI data.

But current implementation only InstallConfigurationTable() at first time ACPI data change.
  if (((Version & EFI_ACPI_TABLE_VERSION_1_0B) != 0) &&
      !AcpiTableInstance->TablesInstalled1) {
    Status = gBS->InstallConfigurationTable (&gEfiAcpi10TableGuid, AcpiTableInstance->Rsdp1);
    if (EFI_ERROR (Status)) {
      return EFI_ABORTED;
    }

    AcpiTableInstance->TablesInstalled1 = TRUE;
  }

  if (((Version & ACPI_TABLE_VERSION_GTE_2_0) != 0) &&
      !AcpiTableInstance->TablesInstalled3) {
    Status = gBS->InstallConfigurationTable (&gEfiAcpiTableGuid, AcpiTableInstance->Rsdp3);
    if (EFI_ERROR (Status)) {
      return EFI_ABORTED;
    }

    AcpiTableInstance->TablesInstalled3= TRUE;
  }

The AcpiTableInstance->TablesInstalled1 and AcpiTableInstance->TablesInstalled3 conditional judgment need to be removed.

Laszlo Ersek f798e8bff7 MdeModulePkg: Acpi: enforce exclusion between FirmwareCtrl and XFirmwareCtrl
The code in AcpiTableDxe handles the installation of FADT and FACS in both
possible orders. In the [FADT, FACS] installation order, the FACS is at
once linked into the FADT. In the [FACS, FADT] installation order, the
FACS is stashed temporarily, and it is linked into the FADT when the FADT
is installed later.

According to the ACPI specification, *at most one* of FADT.FirmwareCtrl
and FADT.XFirmwareCtrl may be nonzero. The code is aware of this
requirement, and it never sets both of them to nonzero values at once.

However, the code doesn't expect the following:

- The caller first installs the FACS, which is stashed. The address that
  is saved happens to fall below 4GB.

- The caller then installs a FADT, with a zero FirmwareCtrl field, and a
  nonzero (pre-populated) XFirmwareCtrl field.

In this case the code sets FADT.FirmwareCtrl to the less-than-4GB address
of the stashed FACS, and leaves the different nonzero value in
FADT.XFirmwareCtrl. This violates the ACPI specification.

Prevent this by always zeroing the field that we do *not* set.
