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

u32 mask

precomputed bitmask for accessing the chip registers

unsigned int irq

interrupt number

unsigned long hwirq

hardware interrupt number, local to the interrupt domain

struct irq_common_data * common

point to data shared by all irqchips

struct irq_chip * chip

low level interrupt hardware access

struct irq_domain * domain

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

struct irq_data * parent_data

pointer to parent struct irq_data to support hierarchy irq_domain

void * chip_data

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