pls, run checkpatch on patches and fix up whatever it complains about
before posting

it doesn't really matter here, that we read bogus core_count2 in case of v2 
tables,
but to be cleaner I'd move reads above below respective 'if's

shouldn't we have a test for #cpus < 256 as well?

[PATCH v2 4/5] bios-tables-test: add test for number of cores > 255

2022-07-31 Thread Julia Suvorova
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.
