[PATCH 0/4] Only generate cluster node in PPTT when specified
Posted by Yicong Yang via 1 year, 7 months ago
From: Yicong Yang <yangyicong@hisilicon.com>

This series mainly change the policy for building a cluster topology node
in PPTT. Previously we'll always build a cluster node in PPTT without
asking the user, after this set the cluster node will be built only the
the user specify through "-smp clusters=X".

Update the tests and test tables accordingly.

Yicong Yang (4):
  hw/acpi/aml-build: Only generate cluster node in PPTT when specified
  tests: virt: update expected ACPI tables for virt test
  tests: acpi: aarch64: add topology test for aarch64
  tests: acpi: aarch64: add *.topology tables

This will need an ack from virt maintainers.

And I think what people are asking is about the impact
of this patch on guests.

Sure.

On the current kernel (tested on 6.1-rc1), there's no impact for the kernel
side, only the cluster node in PPTT is not generated. Booted with `-smp 8`

without this patch:

with this patch:
estuary:/sys/devices/system/cpu/cpu0/topology$ cat cluster_*
ff	# cluster_cpus
0-7	# cluster_cpus_list
56	# cluster_id

with this patch:
estuary:/sys/devices/system/cpu/cpu0/topology$ cat cluster_*
ff	# cluster_cpus
0-7	# cluster_cpus_list
36	# cluster_id, with no cluster node kernel will make it to physical package id

Will send a v2 version and update this information.

Thanks.

Given it's virt machine only, I'd like an ack from relevant maintainers.

> Update the tests and test tables accordingly.
Hi Yicong,

Does this bring an issue with backwards compatibility?
I'm assuming we need to make this something controlled in
virt_machine_7_1_options()?

One of those things we probably should have noticed originally but now
we are stuck with the slightly messy backwards compatibility problem.

Also, looks like you picked up a bunch of tables that are unrelated
to the change.

Hi Jonathan,

Thanks for the comments!

I'm not sure but I cannot come up with one for now. Any hints for this?
Maybe Yanan can shed some light on this since they are using this cluster
feature.

The tables are updated by tests/data/acpi/rebuild-expected-aml.sh so I think
it's doing the proper thing. These tables are introduced due to:

Patch 1 - Don't build the cluster node by default, so the "virt" test is influenced
Patch 2 - Update the expected PPTT table to get rid of the cluster node
Patch 3 - Since the cluster is not tested, add a new test for topology test of all
          level for aarch64, with command "-smp sockets=1,clusters=2,cores=2,threads=2"
Patch 4 - Update the expected tables for the topology test introduced in Patch 3
