Hi My e1000 NIC and another card (Arcnet PCI card) shares the same interrupt. I am busy writing a RTDM driver for the Arcnet card. As I understand it is possible to share interrupts between real-time device drivers?
Anyways, I changed the rt_e1000 driver's rtdm_irq_request() call to pass the RTDM_IRQTYPE_SHARED flag, and did the same to my Arcnet driver. The Arcnet ISR returns RTDM_IRQ_NONE when it is not its interrupt (it seems as though the rt_e1000 also does this correctly?) When I insert the first of the two drivers, everything seems OK. However, when I insert the second driver (the order doesn't seem to matter), rtdm_irq_request() returns -EBUSY. Are there perhaps some steps that I am missing to get shared interrupts working? (I am using RTnet 0.9.6 and RTAI 3.4) Thanks Thinus Viljoen ------------------------------------------------------------------------- Take Surveys. Earn Cash.
