PR/53906: Paul Ripke: systat(1) vmstat & syscall get
"alternate system clock has died" on terminal resize (SIGWINCH)

branches: 1.38.2; 1.38.4;
Use I/O timestamps to compute disk statistics for better precisison.

branches: 1.37.38;
Fix -Wsign-compare issues

branches: 1.36.30;
Update to use new kernel io statistics.

Count both read bytes and write bytes when we are not showing separate read
and write statistics. Discovered by go.
Since I broke in in rev 1.31, I guess I'll fix it first!

Match changes to vmstat.c (splitting of dkreadstats).
Read tape stats if there are no disks found - is this possible?

Add tape statistics.

branches: 1.32.2;
Add an extra digit to the kBps column - now overflows at 100MB/s

Fix field widths for 'numbers' display, and allow it without 'secs'.

Uppercase CPU, plural is CPUs.

Correct boundary conditions for drive table for 'systat io num'.
Correct fix for bin/18823 (which was incomplete and wrong!)

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22365, verified by myself.

Create subwins that end one line from the bottom of the screen even
after the window is resized.

When disk activity exceeds 100kB/s divide length of bar by 10s and report
factor on RHS screen.
(approved by christos)

Prevent the "kBps" field from overflowing for values > 1M/s.

From Paul Shupak in PR 18822.

Remove extra args from a printf.

iostat(8) and systat(8) support for separate read/write disk statistics.
"iostat -x" now shows these (ala linux/solaris), but this is only splitting
the read/write bytes/transactions, not adding any new metrics. "systat
iostat" now has two new commands to switch between combined/separate mode
for both it's numbers & bar modes.

PR/18408: Chris Demetriou: Kilo is abbreviated using a small k not a CAPITAL K.

Since the KERN_CP_TIME sysctl reports total clock ticks across all
cpus and hz is measured in ticks per cpu, divide tick count by ncpu to
determine elapsed time since last sample.

Fixes I/O rate deflation observed on multiprocessors.

format fix in number mode. PR 16911

branches: 1.19.2; 1.19.4;
Make it compile (more vmstat fallout).

comment or delete text after CPP directives.

Remove extern variables and functions now declared in dkstats.h.
While here, remove 77 (!) unneed #includes.

- Add `boot', `run', `time' and `zero' commands to all IP displays. These work
as in the `vmstat' display mode. The default mode is now `time', not `boot'.
- ANSIfy.
- s@kre\(@vmstat\(@.
- __RCSID() police.
- Tweak inet.icmp display visual a little.

branches: 1.15.2;
Use hline() and variants in a bunch of places.

Need to include <sys/sched.h> to get cp_time-related constants.

branches: 1.13.2;
Two things:

1.) fix a bug which caused coredumps when starting with no mode arguments
2.) move to table-lookup for mode-specific command parsing as well.
all command matching is now table-driven.

branches: 1.12.4;
Enlarge disk names in labels from 3 to 7 to cater for things like raid0.

Fix handling of privileges - the gid was given up before dkinit()
was called.
Pass the gid to use for KVM access explicitely to dkinit(), the caller
decides whether to call setgid(getgid()) or not.

- KNF
- use snprintf
- don't overwrite the keyboard buffer (and make this sized on
the window size).

fix .Nm usage, deprecate register, getopt returns -1 not EOF, s/[br]*/[ms]*/

- some KNF.
- use __RCSID().
- WARNS=1

Use the new getmaxx and getmaxy macros instead of directly accessing
the private fields of WINDOW.

Be explicit about iostat transfer rate by displaying `KBps' instead of
`Kps'. As per (and noticed by) J.T.

New userland code to read the statistics kept by the NetBSD generic
disk framework, from John M. Vinopal <banshee@gabriella.resort.com>

Removed a couple of #ifdef vax causing systat to malfunction.

Print out interrupt CPU time.

Changed to conform to NetBSD's new RCS Id convention.
