IRQ sharing

Message-ID: <3A0AD6D3.96690F35@pro.procergs.com.br> Date: Thu, 09 Nov 2000 14:54:43 -0200 From: Flavio Arthur Leal Ferreira Subject: IRQ sharing I installed two RealTek PCI network cards in a firewall box. Both cards are using IRQ 10. It is working. I don't understand how irq sharing works. I had read something about optional support to irq sharing with serial ports. But with PCI bus, is it standard? Does it impact performance? I didn't find any information in pci-howto. Can anybody give some hints? Thanks.
