Currently we'll always generate a cluster node no matter user has
specified '-smp clusters=X' or not. Cluster is an optional level
and it's unncessary to build it if user don't need. So only generate
it when user specify explicitly.
Also update the test ACPI tables.

This is an example of a commit log repeating what the patch does.
Which is ok but the important thing is to explain the motivation -
why is it a bug to generate a cluster node without '-smp clusters'?

It may not be a bug but may build the unneeded topology unconsciously
and doesn't provide a way to inhibit this. So I thought the policy
can be improved.

It would be much more helpful to explain the problem you
have met in practice without this patch. (maybe have some
description or a link of the issue in the cover-letter if we
need a v2).
In qemu which behaves as like a firmware vendor for VM,
the ACPI PPTT is built based on the topology info produced
by machine_parse_smp_config(). And machine_parse_smp_config
will always calculate a complete topology hierarchy using its
algorithm, if the user gives an incomplete -smp CLI.
I think there are two options for us to chose:
1) approach described in this patch
2) qemu will always generate a full topology hierarchy in PPTT
with all the topo members it currently supports. While users
need to consider the necessity to use an incomplete -smp or
an complete one according to their specific scenario, and
should be aware of the kernel behavior resulted from the
config.
There is some Doc for users to explain how qemu will
parse user-specified -smp in [1].

My problem is related to this but not fully caused by this.
I found my schedule domains are not built as expected with command
`-smp 8` and 4 NUMA nodes. The final schedule domains built look
like below with no NUMA domains built.
[ 2.141316] CPU0 attaching sched-domain(s):
[ 2.142558] domain-0: span=0-7 level=MC
[ 2.145364] groups: 0:{ span=0 cap=964 }, 1:{ span=1 cap=914 }, 2:{ span=2 cap=921 }, 3:{ span=3 cap=964 }, 4:{ span=4 cap=925 }, 5:{ span=5 cap=964 }, 6:{ span=6 cap=967 }, 7:{ span=7 cap=967 }
[ 2.158357] CPU1 attaching sched-domain(s):
[ 2.158964] domain-0: span=0-7 level=MC
should be:
[ 2.008885] CPU0 attaching sched-domain(s):
[ 2.009764] domain-0: span=0-1 level=MC
[ 2.012654] groups: 0:{ span=0 cap=962 }, 1:{ span=1 cap=925 }
[ 2.016532] domain-1: span=0-3 level=NUMA
[ 2.017444] groups: 0:{ span=0-1 cap=1887 }, 2:{ span=2-3 cap=1871 }
[ 2.019354] domain-2: span=0-5 level=NUMA
[ 2.019983] groups: 0:{ span=0-3 cap=3758 }, 4:{ span=4-5 cap=1935 }
[ 2.021527] domain-3: span=0-7 level=NUMA
[ 2.022516] groups: 0:{ span=0-5 mask=0-1 cap=5693 }, 6:{ span=4-7 mask=6-7 cap=3978 }
[...]
It's because the MC level span extends to Cluster level which spans
all the cpus in the system, then the schedule domain building stops
at MC level since it already includes all the cpus.
It makes people confusing that cluster node is generated without
asking for it.
A discussion for the problem:

Considering cluster is an optional level and most platforms don't
have it, they may even don't realize this is built and a always
build policy cannot emulate the topology on these platforms.
Also it may influences the build of schedule domains uncousiously
in some cases so...

...I'd prefer 1) then users can generate this *only* when they
explicitly know what they want and what they'll get. A full
topology hierachy generation lacks flexibility. Any thought?

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.

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

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

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.
