1999-03-19 Martin Baulig <martin@home-of-linux.org> Added first kstat based implementation for Solaris 7. * open.c (glibtop_open_s): Walk kstat list and save interesting kstats in the `server->machine'. * cpu.c: This can already provide `idle', `user' and `sys' with full SMP support. * swap.c: This can already provide `total', `used' and `free'.
