https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=294513 Bug ID: 294513 Summary: amd64 loader(8) could do with a hw.ncpu tunable Product: Base System Version: 15.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: dch@freebsd.org At least on arm64, we can limit # of cpus in loader.conf via `hw.ncpu=4` and this is very handy for testing & debugging. There appears to be no equivalent for amd64, other than the brutal `kern.smp.disabled=1`. -- You are receiving this mail because: You are the assignee for the bug.home | help
