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).
