Subject: Buggy idle time reported in /proc/uptime for SMP systems?
Date: Thu, 18 Oct 2007 21:55:13 +0530 [thread overview]
Message-ID: <20071018162513.GA19214@linux.vnet.ibm.com> (raw)
The idle time reported in /proc/uptime (2nd field) seems to be the idle
time of only CPU0. Shouldn't it reflect the total idle time on a SMP system?
Do folks agree that it is a bug that needs to be fixed? If so, will send
a patch ...
Fyi, I see patches submitted to fix this way back in 2001
[http://lkml.org/lkml/2001/3/17/55], but don't think they made in ..
