Command to display struct_irq_data manual in Linux: $ man 9 struct_irq_data

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
