Due to differences in (mainly) measuring and accumulating CPU times, the two top programs end up serving different purposes: the NetBSD top is a system administration tool, while the MINIX3 top (now mtop) is a performance debugging tool. Therefore, we keep both. The newly imported BSD top has a few MINIX3-specific changes. CPU statistics separate system time from kernel time, rather than kernel time from time spent on handling interrupts. Memory statistics show numbers that are currently relevant for MINIX3. Swap statistics are disabled entirely. All of these changes effectively bring it closer to how mtop already worked as well. Change-Id: I9611917cb03e164ddf012c5def6da0e7fede826d

.SH "DEC OSF/1 NOTES"
|
|
Original author was Anthony Baxter, <anthony@aaii.oz.au>.
|
|
Derived originally from m_ultrix, by David S. Comay <dsc@seismo.css.gov>,
|
|
although by now there is hardly any of the code from m_ultrix left.
|
|
Helped a lot by having the source for syd(1), by Claus Kalle, and
|
|
from several people at DEC who helped with providing information on
|
|
some of the less-documented bits of the kernel interface.
|
|
Patches from Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>

Theory of operation:
|
|
Use Mach calls to build up a structure that contains all the sorts
|
|
of stuff normally found in a struct proc in a BSD system. Then
|
|
everything else uses this structure. This has major performance wins,
|
|
and also should work for future versions of the O/S.
