The AMD Threadripper 2990WX is basically a slightly crippled Epyc. Rather than having 4 memory controllers, one per NUMA domain, it has only 2 memory controllers enabled. This means that only 2 of the 4 NUMA domains can be populated with physical memory, and the others are empty. Add support to FreeBSD for empty NUMA domains by: - creating empty memory domains when parsing the SRAT table, rather than failing to parse the table - not running the pageout deamon threads in empty domains - adding defensive code to UMA to avoid allocating from empty domains - adding defensive code to cpuset to avoid binding to an empty domain Thanks to Jeff for suggesting this strategy.
