Bugzilla: 3697 (https://bugzilla.tianocore.org/show_bug.cgi?id=3697)
This patch series updates the Acpiview PPTT parser and DynamicTablesPkg
PPTT generator to support ACPI 6.4. This consists of two main changes:
- The addition of the 'Cache ID' field.
- The removal of the PPTT ID (type 2) structure.
In addition add two 'Cache ID' defines and remove the type 2 PPTT
structure from Acpi64.h as these changes were missing when Acpi64.h was
introduced.
The changes can be seen at: https://github.com/chris-jones-arm/edk2/tree/1632_64_acpi_cache_id_v1

Add Cache ID valid/invalid defines to Acpi64.h which were not initially
added when the CacheIdValid field was added to
EFI_ACPI_6_4_PPTT_STRUCTURE_CACHE_FLAGS.

Bugzilla: 3697 (https://bugzilla.tianocore.org/show_bug.cgi?id=3697)
The ACPI 6.3A specification deprecated the PPTT ID type structure (type
2) therefore remove it from Acpi64.h.

ACPI 6.3A deprecated PPTT ID (type 2) structure which was subsequently
removed in ACPI 6.4. Therefore remove support for generating PPTT ID
structures.

Don't people compile shellpkg for out of tree machines? Are we 100% sure
that there aren't any machines in the wild with older PPTT's using this
structure?
Although, this is less of a problem than below..

I suspect this breaks every single other edk2-platforms machine in this
tree not using the dynamic table generator. AKA all the hardcoded PPTTs
used on synquacer/rpi/etc. I suspect this code path should be able to
deal with multiple versions of the spec.

Hi Liming,
Yes ACPI 6.3A deprecated the ID type structure and ACPI 6.4 fully removed it from the specification.
Thanks,
Chris

Thank you for the review, Liming.
Since uploading the original patch series I noticed some issues myself and have sent a v2 for the patch series (https://edk2.groups.io/g/devel/message/83272). I have not made any MdePkg changes, so I assume your review carries over to the new series?
Thanks,
Chris

Hi Jeremy,
While we have had some discussions internally, I thought I would share these with the rest of the list for those interested.
No, this patch series does not break either build or runtime compatibility. If anyone tries to build an old table with PPTT ID type (type 2) structures then Acpiview will flag an error and not parse the structure however this only affects Acpiview and DynamicTablesPkg. Normally we would want a version check to ensure that old systems using the feature can still run and pass Acpiview validations however in this case that is not what we want. The type 2 structures were deprecated in an errata (ACPI 6.3A) and subsequently removed in ACPI 6.4. The original bugzilla ticket for removing the structure (https://bugzilla.tianocore.org/show_bug.cgi?id=2492) shows that the structure should not have been added in the first place hence it being removed before anyone had a chance to use it.
If anyone is using PPTT type 2 structures then they are doing so mistakenly and should replace those structures with the alternative SMCCC API architectural call (SMCCC_ARCH_SOC_ID).
Thanks,
Chris

Don't people compile shellpkg for out of tree machines? Are we 100% sure
that there aren't any machines in the wild with older PPTT's using this
structure?
Although, this is less of a problem than below..

I suspect this breaks every single other edk2-platforms machine in this
tree not using the dynamic table generator. AKA all the hardcoded PPTTs
used on synquacer/rpi/etc. I suspect this code path should be able to
deal with multiple versions of the spec.

Thank you for the review, Liming.
Since uploading the original patch series I noticed some issues myself and
have sent a v2 for the patch series
(https://edk2.groups.io/g/devel/message/83272). I have not made any MdePkg
changes, so I assume your review carries over to the new series?
Thanks,
Chris
