In order to use the increased number of cpus, we need to bring smbios
tables in line with the SMBIOS 3.0 specification. This allows us to
introduce core_count2 which acts as a duplicate of core_count if we have
fewer cores than 256, and contains the actual core number per socket if
we have more.
core_enabled2 and thread_count2 fields work the same way.

on the other hand,
is it ok unconditionally extend type 4 and use v3 structure
if qemu was started with v2 smbios?

We have a flag for the entry point type, not the smbios version per
se. Additional fields added to structures were not previously tracked
(for instance, processor_family2 is v2.6 and status is v2.0). AFAIU it
can affect only the total table length and the maximum structure size
(word). But if you like, I can raise an error (warning) if someone
tries to start a vm with cpus > 255 and smbios v2.

table length is fixed depending on used version,
so if we follow it, we should set length and use part of structure
correctly if old version is specified (i.e.
1. old structure + v30 structure,
2. copy only a relevant part of v30 structure and
fixup length when v2 version is asked for

it's a separate thing, I'd error out
(it will break users that use v2 with too may CPUs but then
they should fix their configuration to use v3)

Introduce the 64-bit entry point. Since we no longer have a total
number of structures, stop checking for the new ones at the EOF
structure (type 127).

This is quite an unreadable way to specify the loop condition. I
wonder if there is a better way to structure this.
Secondly, instead of hardcoding 127 why do we not say (type < SMBIOS_MAX_TYPE) ?

Here we are looking for a special structure type 127. There can be up
to 256 structure types, and they can be placed before the final
structure.
But it seems like we need to change SMBIOS_MAX_TYPE in the test.

keep original v2 code and just add similar chunk for v3,
drop found_foo locals,
that should make it easier to read/follow
(i.e. less conditions to think about and no magic fiddling with the length of signature)

The new test is run with a large number of cpus and checks if the
core_count field in smbios_cpu_test (structure type 4) is correct.
Choose q35 as it allows to run with -smp > 255.

while you are at it, I suggest renaming this to real_speed or some such so
that its better redeable.

How about checking thread count as well in the same test or in a
different test?

The check is not whether it fits into the field, but whether the field
is initialized.

Maybe a different test.

yes so the real_cc will contain the actual value of core count only
when the core count value is less than 256. This value should be the
same as the expect_cc (the cc value we pass). Is this not what is
being tested?

The real_cc should always be equal to expect_cc (which is 0xFF with
-smp 275). So if the core count is less than 256, this checks for the
actual core counter, and if it's over, it checks if real_cc is equal
to 0xFF, which eliminates several unnecessary comparisons. If we
didn't initialize expect_cc in the test, the value is undefined, and
we shouldn't check anything.

I have convinced myself that the logic is correct. You are right in
that real_cc should always be equal to expect_cc when expect_cc is set
(either to actual core count or to 0xff when number of cores > 255).

since you are rewriting it anyways, how about

change the original code too.
