Indeed, this was a small step towards lifting some of the code in x86/acpica/srat.c into the generic driver for use on arm64. In my case I'm looking a ThunderX, which exposes NUMA locality info in both the ofw device tree and the SRAT table. I'm looking at ofw first, and in the meantime I just needed a buildable options NUMA kernel. _______________________________________________ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
