> 主题: [edk2-devel] [PATCH v1 0/7] Support ACPI 6.4 PPTT changes
>
> 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:
