I read about the MSI interrupt handling for FreeBSD, and I don't know if there's a way to split the interrupt request for each bce's Rx and Tx, which means a total of four IRQs, and eventually four cores (or 4 CPU) for the transactions. With this way, the IDLE processors would be utilized. Other ways how I can maximize the use of the IDLE CPUs? Thanks, Won --------------------------------------------------------------------------------------------------------------------------- ________________________________ From: Jeremy Chadwick <koitsu@FreeBSD.org> To: Won De Erick <won.derick@yahoo.com> Cc: freebsd-hardware@freebsd.org Sent: Thursday, November 13, 2008 3:26:10 PM Subject: Re: IRQ31 and IRQ32 on HPDL585 running FreeBSD 7.0 are consuming HIGH CPU usage On Wed, Nov 12, 2008 at 10:55:06PM -0800, Won De Erick wrote: > Hello, Nobody can read the pasted output you've sent.
