From: Zhao Liu <zhao1.liu@xxxxxxxxx> Currently, QEMU checks the specify number of topology domains to detect if there's extended topology levels (e.g., checking nr_dies). With this bitmap, the extended CPU topology (the levels other than SMT, core and package) could be easier to detect without touching the topology details. This is also in preparation for the follow-up to decouple CPUID[0x1F] subleaf with specific topology level. Tested-by: Yongwei Ma <yongwei.ma@xxxxxxxxx> Signed-off-by: Zhao Liu <zhao1.liu@xxxxxxxxx>
