This patch series provides the following updates:
- The patches 1 & 2 add the new fields introduced
  in MADT (APIC table) by ACPI 6.5 and the patch
  7/11 updates the Acpiview MADT parser accordingly.
- The patches 3, 4 & 5 adds TRBE support to the MADT
  table generator in DynamicTablesPkg.
- Patch 6/11 updates the FADT ACPI revision to 6.5.
- The patches 8, 9 & 10 add support to generate ETE
  device nodes.
- The last patch series fixes a bug wherein the CPC
  token was incorrectly referenced.

The changes can be seen at:

Bugzilla: 3706 'Code First - MADT GICC new flags'

On ARM systems physical CPU hotplug is not supported.
All CPUs are considered present and this is true
throughout the system uptime.

The ECR 2285 introduces a new 'online-capable' flag
in the GICC structure flags in ACPI 6.5, to signal
firmware policy (CPU is not enabled but it can be
enabled and onlined). This enables OSPM to support
virtual CPU hotplug (on virtual platforms for
instance).

This ECR also updates the MADT table revision to 6
to reflect the ACPI 6.5 changes. Therefore, update
the MADT table revision to match the value as
specified in ACPI 6.5.

TRBE interrupt is a Processor Private interrupt (PPI) and is
used to specify a platform-specific interrupt to signal TRBE

This field has already been added to the CM_ARM_GICC_INFO
structure in a previous patch.

Therefore, update the Configuration Manager Object Parser to
reflect the addition of the TRBE interrupt field.

The ACPI 6.5 specification updates the MADT table to add
a new field to GICC for specifying the TRBE interrupt and
also adds support for Online Capable flag to the GICC flags.

The Online Capable flags should be passed transparently
through as specified in the CM_ARM_GICC_INFO.Flags field
and only require the MADT table revision to be setup to
6 to reflect the ACPI 6.5 specification.

The TRBE field needs to be appropriately setup in the
GICC structure.

Therefore, update the MADT generator to reflect the
above updates required for supporting ACPI 6.5

The ACPI 6.5 specification updates the minor revision
of the FADT table to 5. Therefore, update the FADT
generator to setup the minor revision for ACPI 6.5.

ACPI 6.5 introduces a new filed to the MADT GICC
structure to specify the TRBE interrupt. The TRBE
interrupt is a Processor Private interrupt (PPI)
and is used to specify a platform-specific
interrupt to signal TRBE events.

Therefore, update the MADT GICC structure parser
to parse the new TRBE interrupt field. Also, add
validations to check that the TRBE interrupt is
within the PPI interrupt range.

Add an Embedded Trace (ET) info object that can be
used to provide information about Embedded Trace
Extension (ETE) or Embedded Trace Module (ETM)
available on a platform.

Although ETE and ETM share the same HID,
ETE has a system register interfaces, unlike
ETM which requires memory mapped registers.

Since this patch aims to support ETE it does
not describe any memory mapped registers.
However, required support for ETM can be added
in the future.

An Embedded Trace (ET) info object is used to provide
information about an Embedded Trace Extension (ETE) or
an Embedded Trace Module (ETM) available on a platform.

The CM_ARM_ET_INFO object has already been added to the
Arm namespace objects list by a previous patch.

Therefore, update the CM Object parser to add support
for parsing the CM_ARM_ET_INFO object.

The Coresight Embedded Trace Extension (ETE) feature
can be detected by the platform firmware by examining
the debug feature register ID_AA64DFR0_EL1.TraceVer
field.
The platform configuration manager can then describe
the ETE by creating CM_ARM_ET_INFO object(s) and
referencing these in CM_ARM_GICC_INFO.EtToken.

The 'Table 3: Compatible IDs for architected
CoreSight components' in the 'ACPI for CoreSight
1.2 Platform Design Document' specifies the HID
value for Coresight ETE and CoreSight Embedded
Trace Macrocell (ETM) v4.x as ARMH C500.

Therefore, update the SsdtCpuTopologyGenerator
to add an ETE device to the CPU node in the AML
CPU hierarchy so that an OS can utilise this
information.

Note: Although ETE and ETM share the same HID,
ETE has a system register interfaces, unlike
ETM which requires memory mapped registers.
Since this patch aims to support ETE, the AML
description does not describe any memory mapped
registers. However, support for ETM can be
added in the future.

The CpcToken has been incorrectly referenced in the
CreateTopologyFromGicC() and always points to the
CPC token in the first GICC Info object.

Therefore, fix this by correctly indexing into the
GicCInfo object array.

It looks like you are setting the wrong field here (should be TrbeInterrupt, not SpeOverflowInterrupt):
+    // Setting TrbeInterrupt to 0 ensures backward compatibility with
+    // ACPI 6.4
+    Gicc->SpeOverflowInterrupt = 0;

Subject: [edk2-devel] [PATCH v1 05/11] DynamicTablesPkg: Update MADT generator for ACPI 6.5

External email: Use caution opening links or attachments


The ACPI 6.5 specification updates the MADT table to add a new field to GICC for specifying the TRBE interrupt and also adds support for Online Capable flag to the GICC flags.

The Online Capable flags should be passed transparently through as specified in the CM_ARM_GICC_INFO.Flags field and only require the MADT table revision to be setup to
6 to reflect the ACPI 6.5 specification.

The TRBE field needs to be appropriately setup in the GICC structure.

Therefore, update the MADT generator to reflect the above updates required for supporting ACPI 6.5
