SA_INTERRUPT or SA_SHIRQ

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi All,

If I register an ISR using both the flags SA_INTERRUPT and SA_SHIRQ set, what kind of interrupt line will I get a dedicated one or a shared one ?
the exact definition is

request_irq(dev->pci_dev->irq, soc_intr, SA_INTERRUPT | SA_SHIRQ,
                      MODULE_NAME, dev);

thanks in advance,
Devendra
