STRUCT IRQ_DATA(9)                          Structures                         STRUCT IRQ_DATA(9)



NAME
       struct_irq_data - per irq chip data passed down to chip functions

SYNOPSIS
       struct irq_data {
         u32 mask;
         unsigned int irq;
         unsigned long hwirq;
         struct irq_common_data * common;
         struct irq_chip * chip;
         struct irq_domain * domain;
       #ifdef CONFIG_IRQ_DOMAIN_HIERARCHY
         struct irq_data * parent_data;
       #endif
         void * chip_data;
       };

MEMBERS
       mask
           precomputed bitmask for accessing the chip registers

       irq
           interrupt number

       hwirq
           hardware interrupt number, local to the interrupt domain

       common
           point to data shared by all irqchips

       chip
           low level interrupt hardware access

       domain
           Interrupt translation domain; responsible for mapping between hwirq number and linux
           irq number.

       parent_data
           pointer to parent struct irq_data to support hierarchy irq_domain

       chip_data
           platform-specific per-chip private data for the chip methods, to allow shared chip
           implementations
