Browse Source 
* glibtop_machine.h: added fields for page size, clock ticks and
        boot time. These are constants. Also added three new kstats.

        * open.c (glibtop_get_kstats): Initialize kstats in *server.
        We need to call this at init time (obviously) and each time
        kstat_chain_update() says that kstat chain has changed. In this
        case all kstat pointers and data are invalid, so we need to
        reinitialize everything.

        (glibtop_open_s): Made it call glibtop_get_kstats(). Added
        initialization for run time constants in struct machine.

        * cpu.c (glibtop_get_cpu_s): Call kstat_chain_update().
        See if processor is on-line and set bits in xcpu_flags.
        Added frequency (bad name, should have been ticks).

        * swap.c (glibtop_get_swap_s): Call kstat_chain_update().
        I probably broke vminfo_snaptime consistency. Fix later.

        * uptime.c (glibtop_get_uptime_s): Implemented uptime and boot_time.
        Still looking for a sane way to get idletime.

        * mem.c (glibtop_get_mem_s): Implemented. Will use bunyip
        module if it's loaded. Or when it gets loaded. kstat_chain_update()
        is our friend. And with a friends like that...

        * loadavg.c (glibtop_get_loadavg_s): Solaris 2.6 code brought
        into sync with everything else.

        * msg_limits.c (glibtop_init_msg_limits_s): Implemented.

        * sem_limits.c (glibtop_get_sem_limits_s): Implemented.

        Solaris takes kernel modularity too seriously. We can't get
        IPC configuration data if the kernel module is not loaded and
        it won't be loaded until some process actually asks for a
        particular IPC resource. There's no way to tell our applications
        about this. Possible API additions?

        All three IPC functions should go into daemon, but I'm keeping
        them in the normal library because I can't build daemon yet. All
        praise 64 bits!
