For reasons we don't understand, the plug & play system moved the IRQ for our custom board to share an IRQ with the Ethernet controller. Now when we try to install our custom RTLinux module the Ethernet interface dies.
We looked in ...MAN\rtl_request_irq.3.html, which says "If it is necessary to receive further interrupts from this device, you must reenable the interrupt line with the rtl_hard_enable_irq(3) function."; after the reply by Yodaiken on 9/12, it sounds like this sentence was meant to cover only highly unusual cases, and a normal RTLinux interrupt handler should just handle and clear the associated interrupt source and then return. Right?? Even if we leave the interrupts on our custom board disabled and install an interrupt handler that just executes a return 0, installing the module with a shared IRQ still kills the Ethernet interface that shares the IRQ. Do we need to do anything in our interrupt handler to support shared interrupts? Is there anything that we can do to force a unique IRQ for our plug and play board?
