So, I was looking at a v240 I have running stable/9 (9.1-STABLE), and =
noticed something odd. The per-CPU information displayed by top seems =
inconsistent. To simplify things, while I'm running a "make release" in =
/usr/src/release, I just started running the following command over and =
over (by hand):
cross: top | grep " CPU"
cross: top | grep " CPU"
1044 cross 1 72 0 17128K 4464K CPU1 0 0:01 1.27% zsh
22528 root 1 77 5 11672K 2592K CPU1 1 0:00 0.00% sh
cross: top | grep " CPU"
cross: top | grep " CPU"
22634 cross 1 72 0 12808K 2872K CPU1 1 0:00 0.00% top
22633 root 1 77 5 6272K 880K CPU0 1 0:00 0.00% =
make
cross: top | grep " CPU"
22637 root 1 77 5 6272K 1656K CPU0 0 0:00 0.00% =
make
cross: top | grep " CPU"
cross: top | grep " CPU"
22684 root 1 77 5 11672K 2592K CPU0 0 0:00 0.00% sh
cross:
This displayed what I had earlier seen in the full-screen top. There =
doesn't appear to be any specific binding between the "n" in the "CPUn" =
state value, and the number in the "C" column, which is according to the =
man page, should mean the same thing.
Is this a sparc64 problem, a generic FreeBSD SMP problem, or not a =
problem at all and I'm misunderstanding something?
Thanks=85
