[PATCH v2 03/16] tests: bios-tables-test: Add test for smbios type4 count |

From: Zhao Liu <zhao1.liu@intel.com>
This tests the commit d79a284a44bb7 ("hw/smbios: Fix smbios_smp_sockets
calculation").
In smbios_get_tables() (hw/smbios/smbios.c), smbios type4 table is built
for each socket, so the count of type4 tables should be equal to the
number of sockets.
Thus for the topology in this case, there're the following considerations:
1. The topology should include multiple sockets to ensure smbios could
create type4 tables for each socket.
2. In addition to sockets, for the more general topology, we should also
configure as many topology levels as possible (multiple dies, no
module since x86 hasn't supported it), to ensure that smbios is able
to exclude the effect of other topology levels to create the type4
tables only for sockets.
3. The original miscalculation bug also misused "smp.cpus", so it's
necessary to configure "cpus" (presented threads for machine) and
"maxcpus" (total threads for machine) as well to make sure that
configuring unpluged CPUs in smp (cpus < maxcpus) does not affect
the correctness of the count of type4 tables.
Based on these considerations, select the topology as the follow:
-smp cpus=100,maxcpus=120,sockets=5,dies=2,cores=4,threads=3
The expected count of type4 tables = sockets (5).
