Want ps with symbolic wait channel info

[Dave Yost]

Many years ago at Usenix in Austin, Texas (wadda time!)
the now-famous George Goble of Purdue showed a film of
a continuous ps display running on a sattelite
processor which peeked into the /dev/mem of its planet.
One wonderful little feature of this was that the wait
channel was listed symbolically.  Oh, such a useful
feature!  I put that capability into the Fortune ps and
kernel a couple of years ago.  Has anyone done it for
4.2, and would they please tell me about it and send it
to Berkeley?  Thanks.

It's also nice to be able to get valid information no
matter where the vmunix you booted from is.  You just
put pointers to everything in nailed-down places in
kernel memory and have ps, pstat, vmstat, etc. look
there instead of in the symbol table of /vmunix.

A Fortune ps looks like this:

% ps alx
   FLAGS S UID   PID  PPID CPU PRI NICE SZ WCHAN     TTY TIME CMD
      KC S   0     0     0 211   0   20  2 runout    ?  534:53 swapper
       C S   0     1     0   0  30   20  8 (wait)    ?   0:11 /etc/init 
       C S   0   894     1   0  40   20 23 (pause)   ?   0:01 /etc/cron 
       C S 101   904     1  18  30   20 52 (wait)    co  0:21 -csh 
       C S   0   907     1   0  25   20  8 tty6,2+56 ?   0:00 /etc/init 
       C S   0   961     1   0  29   20 15 tty6,0+28 02  0:00 - n 
       C S 101   985     1   3  30   20 43 (wait)    01  0:22 -csh 
       C R   0   994   985  36  51   20 20           01  0:01 ps alx 
       C S 101   995   904  15  21   20 45 buf[3]    co  0:00 cat /etc/termcap 

While we're at it, check these out:

% vmstat -c
--Procs-  Traps/sec  -----%Cpu----- ---Int priority--  Non-int priority
RQ DW SW INT SYS CSW US NI SY IN ID  5  4  3  2  1  0  5  4  3  2  1  0
 1  1  0   0   0   0  2  0  2  0 96  0  0  0  0  0  0  0  0  0  0  0100

And would you believe pstat -u takes a pid instead of a upage address?

% pstat -u 985
