Like I answer Oak's question,
"For GCD parsing, the relation of GCD to CCD is defined by AMD, generic
parsing in srat.c is considering a GCD as a new numa node which is not
suitable for our need."
GCD's pxm domain will get a wrong numa node which may be bigger than CCD
domains, so I have to d

Why numa node number is compared to a proximity domain? Since you are already
using pxm_to_node() API, assume that should take care.
That also will avoid parsing ACPI_SRAT_TYPE_CPU_AFFINITY structs.

Ok, that makes sense. Thanks for explaining.

In drivers/acpi/numa/srat.c, the generic CCD parsing is for the mapping
of numa node and pxm domain that creates arrays of pxm_to_node_map and
node_to_pxm_map. We are currently using API pxm_to_node() to get the
corresponding information.
For GCD parsing, the relation of GCD to CCD is defined

I feel such parsing work should be part of the ACPI generic work so should be
done in drivers/acpi/num/srat.c (see acpi_table_parse_srat) and the acpi
subsystem should expose APIs for rest drivers to query such numa information.

Thanks Felix for your review. I will send another patch.
