回复: [edk2-devel] [PATCH v2 0/8] IORT Rev E.b specification updates

["gaoliming" <gaoliming@byosoft.com.cn>]

Sami:
  I agree this change. With this patch, will you update the existing
platform to use the matched version macro EFI_ACPI_IO_REMAPPING_TABLE_REV0? 

Thanks

>           (https://bugzilla.tianocore.org/show_bug.cgi?id=3458)

> The IO Remapping Table (IORT) specification has been updated to
> rev E.b. The following updates are introduced including the errata
> to rev E and E.a:
>   - increments the IORT table revision to 3.
>   - 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.
> 
> The v1 patch series:
>   - Updates the IORT header file to match the Rev E.b specification.
>   - Add support to parse IORT Rev E.b tables
>   - Add support to generate IORT Rev E.b compliant ACPI tables
>     using Dynamic Tables Framework.
> 
> This v2 patch series includes all changes from v1 patch series
> except the following 2 patches have been modified to set the
> EFI_ACPI_IO_REMAPPING_TABLE_REVISION macro to Rev 0 as setting
> to Rev 3 will break existing platforms, the problem being that
> the Identifier field in the IORT nodes would not be unique.
