[patch 1/3] genirq: Add config option for reservation mode

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

 



The interrupt reservation mode requires reactivation of PCI/MSI
interrupts. Create a config option, so the PCI code can set the
corresponding flag when required.
