Only Cascadelake-AP CPUs appear to report "die_id" values != 0 on Linux right now - AMD EPYC's don't report "die_id" (at least with Fedora 31 kernel). Lacking access to Cascadelake-AP CPUs, this test data was from a Fedora 31 QEMU guest launched with -cpu qemu64 -smp sockets=2,dies=3,cores=2,threads=1 Ideally we'd replace this data with some from a real machine reporting "die_id", to ensure we're not mislead by QEMU's impl.
