[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v2 04/21] xen/arm: vgic: Introduce a function to initialize pending_irq
The structure pending_irq is initialized on the same way in 2 differents place. Introduce vgic_init_pending_irq to avoid code duplication. Also move the setting of the irq field in this function as we need to initialize it once rather than every time an IRQ is injected to the guest.
