(polled I/O did) Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-mobile@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org I tried: 1) Enabling sio3 in the kernel config (didn't work) 2) Changing the modem card to sio1 and using different interrupts (didn't work) 3) Changing the modem card to use polled I/O (worked) However, if I remember right, polled I/O takes a *serious* performance hit over interrupt-driven I/O. Is there anything equivalent to "cat /proc/interrupts" in Linux that will tell you what interrupts are being used for what purposes? How can I successfully find a non-conflicting interrupt? Your assistance will be appreciated. Thank you. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
