I missed this the first time. I think at a minimum the VENDOR_ID needs
to contain something other than 0 if your populating a type2 structure.
Did I miss it getting overridden somewhere?
Checking the ACPI id, registry there is an existing entry for Hisilicon
Technologies Co.., LTD and its 'HISI'.
I would suggest you use that, and come up with a plan for how the
remaining fields are provided.

I think these two flags belong in the acpi header file.. That said they
are already defined by the bitfields in
EFI_ACPI_6_2_PPTT_STRUCTURE_PROCESSOR_FLAGS so it might be a good idea
to just remove them and convert the following definitions to the struct.
That said, its a bit ugly either way, so your choice.

Its more clear for these two, they should be in the acpi header file.
While your at it the write policy and cache type should also probably be
defined and used in your init routing.

This feels like it belongs in a diffrent header file closer to the
ReadCCISDR() function (ArmLibPrivate.h).

+typedef struct {
+ UINT8 Type;
+ UINT8 Length;

+ UINT32 Flags;
+ UINT32 Parent;
+ UINT32 AcpiProcessorId;
+ UINT32 NumberOfPrivateResources;
+} EFI_ACPI_6_2_PPTT_TYPE0;
This belongs in the common ACPI header too.

Ok, so other than the above comments i'm pretty happy with it. IMHO the
largest problem is the Type2 id definition which definitly needs to be
'HISI'.

Generally, I think this is a pretty good way to build the table. Enough
so, that the next person to do an arm PPTT implementation should make an
effort to move some of your helper functions (InitCacheInfo, Add*
routines) into a generic library and tweak them enough that they can be
resused across multiple platforms.
Thanks,
