SYSCTL (7) NetBSD Miscellaneous Information Manual SYSCTL (7) hw.ncpu (HW_NCPU) The number of CPUs. hw.pagesize (HW_PAGESIZE) The software page size. hw.physmem (HW_PHYSMEM) The bytes of physical memory as a 32-bit integer. hw.physmem64 (HW_PHYSMEM64) The bytes of physical memory as a 64-bit integer. hw.usermem (HW_USERMEM) The bytes of non-kernel memory as a 32-bit integer. hw.usermem64 (HW_USERMEM64) The bytes of non-kernel memory as a 64-bit integer. The kern.∗ subtree The string and integer information available for the kern level isdetailed below. The changeable column shows whether a process with appropriate privilege may change the value. The types of data currently available are process information, system vnodes, the open file entries, routing table entries, virtual memory statistics, load average history, and clock rate information.

If set to 0, automatic lowering of priority is not performed, and if set to −1 all non-root processes are immediately lowered. NetBSD 3.0 December 27, 2007 4
