Do you have further ideas for buddy cpu on such example?
Which kind of sched_domain configuration have you for such system ? and how many sched_domain level have you ?
it is general X86 domain configuration. with 4 levels, sibling/core/cpu/numa.
CPU is a bug that slipped into domain degeneration. You should have SIBLING/MC/NUMA (chasing that down is on todo).
Maybe. the CPU/NUMA is different on domain flags, CPU has SD_PREFER_SIBLING.
