Edward Pickup 4d83ee04f4 ShellPkg: Add revision check for DSDT Header on Arm
Bugzilla: 3995 (https://bugzilla.tianocore.org/show_bug.cgi?id=3995)

ACPI 6.4 spec states that if the revision field in the DSDT header is less
than 2, then all integers are restricted in width to 32 bits, including in
SSDTs.

Arm Base boot requirements state that platforms must conform to ACPI 6.3
or later, and that legacy tables are not supported.

Adds a check for this field and raise warning if revision is less
than 2 on arm.

Sami Mujawar cd67efa1b2 ShellPkg: Acpiview: IORT parser update for IORT Rev E.d spec
Bugzilla: 3458 - Add support IORT Rev E.d specification updates
          (https://bugzilla.tianocore.org/show_bug.cgi?id=3458)

The IO Remapping Table, Platform Design Document, Revision E.d,
Feb 2022 (https://developer.arm.com/documentation/den0049/)
introduces the following updates, collectively including the
updates and errata fixes to Rev E, Rev E.a, Rev E.b, Rev E.c:
 - increments the IORT table revision to 5.
 - updates the node definition to add an 'Identifier' field.
 - adds definition of node type 6 - Reserved Memory Range node.
 - adds definition for Memory Range Descriptors.
 - adds flag to indicate PRI support for root complexes.
 - adds flag to indicate if the root complex supports forwarding
   of PASID information on translated transactions to the SMMU.
 - adds flag to indicate if the root complex supports PASID.
 - adds flags to define access privilege and attributes for the
   memory ranges.

Therefore, update the IORT parser to:
  - parse the Identifier field.
  - parse Reserved Memory Range node.
  - parse Memory Range Descriptors.
  - add validations to check that the physical range base
    and size of the Memory Range Descriptor is 64KB aligned.
  - add validation to check that the IORT Table Revision is
    not 4 as IORT Rev E.c is deprecated.
  - add validation to check that the IORT RMR node revision
    is not 2 as it breaks backward compatibility and was
    deprecated as part of IORT Rev E.c.
  - skip parsing of IORT Rev E, Rev E.a, Rev E.b, Rev E.c as
    some fields were deprecated in these revisions.

Krzysztof Koch b85048261a ShellPkg: acpiview: Prevent infinite loop if structure length is 0
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2534

Extend validation of ACPI structure lengths which are read from the
ACPI table being parsed. Additionally check if the structure 'Length'
field value is positive. If not, stop parsing the faulting table.

Some ACPI tables define internal structures of variable size. The
'Length' field inside the substructure is used to update a pointer used
for table traversal. If the byte-length of the structure is equal to 0,
acpiview can enter an infinite loop. This condition can occur if, for
example, the zero-allocated ACPI table buffer is not fully populated.
This is typically a bug on the ACPI table writer side.

In short, this method helps acpiview recover gracefully from a
zero-valued ACPI structure length.

Krzysztof Koch 62cefaf44e ShellPkg: acpiview: IORT: Prevent buffer overruns
Modify the IORT table parsing logic to prevent reading past the buffer
lengths provided.

Change DumpIortNodeIdMappings() function's signature and implementation
to simplify buffer overrun prevention. Update all calls to this
function accordingly.

Modify the parser for each type of IORT node such that the offset from
the start of the node's buffer is tracked as the parsing function is
executed. Again, this change helps prevent buffer overruns.

Test that the IORT node buffer fits in the table buffer before the
node's buffer contents are dumped.

Krzysztof Koch 1d12f0e671 ShellPkg: acpiview: GTDT: Prevent buffer overruns
Modify the GTDT table parsing logic to prevent reading past the ACPI
buffer lengths provided and to make it consistent with other table
parsers. This includes converting the do-while loop in ParseAcpiGtdt()
into a while loop.

Remove a check which ensures that the entire Platform GT Block
Structure buffer has been parsed. The ACPI specification does not ban
from defining buffers which are larger than the size indicated by the
count and sizes of substructures which constitute it.

Change the data type of the Length parameter to the DumpGTBlock()
function to reflect the width of the respective ACPI structure's
field.

Krzysztof Koch ffb18f7710 ShellPkg: acpiview: DBG2: Prevent buffer overruns
Modify the DBG2 table parsing logic to prevent reading past the ACPI
buffer lengths provided.

Modify the signature of the DumpDbgDeviceInfo() function to make it
consistent with the ACPI structure processing functions in other
acpiview parsers. Now, the length of the Debug Device Information
Structure is read before the entire structure is dumped.

This refactoring change makes it easier to stop reading beyond the
DBG2 table buffer if the Debug Device Information Structure Buffer
does not fit in the DBG2 buffer.

For processing the first two fields of the Debug Device Information
Structure (to get the length) a new ACPI_PARSER array is defined.

Michael D Kinney eb2a1ed56f ShellPkg/AcpiView: Fix IA32 link error
https://bugzilla.tianocore.org/show_bug.cgi?id=1970

Update SLIT_ELEMENT() macro to use MultU64x64() to
perform multiplication on 64-bit operands.  This is
required to avoid use of an intrinsic on IA32 VS20xx
builds.

Krzysztof Koch 05f8e85fa7 ShellPkg: acpiview: IORT: Refactor PMCG node mapping count validation
Move Performance Monitoring Counter Group (PMCG) node ID mapping count
validation from the core IORT acpiview parser logic to a dedicated
function. Now, the pointer to the validation function is passed to the
IortNodePmcgParser[] ACPI_PARSER array.

This check does not affect the flow of IORT parsing and is limited to
a single table field in scope, therefore, it is better to keep it away
from the code responsible for traversing the table.

Krzysztof Koch d23bf79734 ShellPkg: acpiview: MADT: Split structure length validation
Split the Interrupt Controller Structure length validation in the
acpiview UEFI shell tool into two logical parts:
1. Ensuring MADT table parser forward progress.
2. Preventing MADT table buffer overruns.

Also, make the condition for infinite loop detection applicable to
all types of Interrupt Controller Structures (for all interrupt models
which can be represented in MADT). Check if the controller length
specified is shorter than the byte size of the first two fields
('Type' and 'Length') present in every valid Interrupt Controller
Structure.

Krzysztof Koch e0cf5ac693 ShellPkg: acpiview: RSDP: Make code consistent with other parsers
List ParseAcpi() function arguments one per line in order to make this
function call consistent with ParseAcpi() calls in other ACPI table
parsers.

Also, notify the user that XsdtAddress value of 0 results in RSDP
parsing being terminated and that the XSDT table will not be processed.

This effectively means that no more ACPI tables will be parsed because
of this RSDP table content error.
