Giant lock, bce and uhc using the same irq

[Murat Balaban]

Hello hackers,

In one of my production servers (64-bit Intel Xeon machine) running

6.3-RELEASE-p4 (amd64) FreeBSD 6.3-RELEASE-p4 #0: Fri Sep 12 17:07:19
EEST 2008

I see this "top -S" output excerpt:

32 root          1 -68 -187     0K    16K *Giant 0  48.3H  3.08% irq17:
bce1 uhci1

What I get from above is that bce and uhc drivers both use irq17. I
assume
bce is SMPng'ed, and uhc is not.

Does uhc being Giant locked, affect bce performance, because they use
the same
interrupt handler thread?
