Hello there,
My PCI device driver disables ethernet card IRQ upon loading and thus
causing ethernet to fail to connect to Internet. This is on Fedora Core
5, 2.6.11 onwards. I have not checked any previous kernel versions. Most
unfortunate is that the irq is not being shared by the devices. But, my
driver implements SA_SHIRQ to enable sharing.
Do you think using spin_lock_irq_save and restore functions be of any
help? If so, where exactly do you think I should use them. Should it be
used in the interrupt handler method or in the open method where I have
request_irq? I read the interrupt handling chapter of device drivers 3rd
edition. I could not find a real good explanation in there.
Can anyone please help?
Thanks,
Dinesh
