Please correct me, if I'm about smth. different, but isn't it already? /sys/amd64/include/param.h:#define MAXCPU 32 /sys/arm/include/param.h:#define MAXCPU 2 /sys/i386/include/param.h:#define MAXCPU 32 /sys/ia64/include/param.h:#define MAXCPU 32 /sys/mips/include/param.h:#define MAXCPU MAXSMPCPU /sys/powerpc/include/param.h:#define MAXCPU 2 /sys/sparc64/include/param.h:#define MAXCPU 16 /sys/sun4v/include/param.h:#define MAXCPU 32 (almost 2y ago for x86) -- wbr, pluknet _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
