Weird? Daemon showing up in 'top'

[Richard.Hubbard at nhwny.com]

Thank you!

I was not nearly so presumptuous to call it a bug. (That implies that I am
knowledgeable enough to understand what it should look like!)  But it is
reassuring to know that the kernel isn't using 94% of it's time asking 'is
anything happening yet?')

Thanks to all for all the help in the past couple of days.  I'll be able to
bring 'hermione' on line soon to show at least this corner of the world
that linux on a crippled desktop still beats NT on a couple of monster
servers!

>>From a Linux listserv:


The message quoted below is from a MandrakeSoft co-worker and friend, in
a thread discussing APM's kernel thread, and how the idle function uses
CPU time. This thread was in response to yet another Bugzilla bug
report about kapm-idled using CPU time.


Several months ago, kapmd was renamed to kapm-idled in an attempt to
signal users that it was a special process, and that its CPU time wasn't
"real CPU time." This hasn't silenced the bug reports and confusion.


Is there some way to hack the scheduler statistics so that idle
processes are special cases, which do not accumulate CPU time nor
contribute to the load average?


I agree that it's not pretty to special case idle function process(es),
but those idle functions in turn are causing an incorrect picture of the
system state to be presented to userland.
