STRUCT
IRQ_DATA(9) Structures STRUCT IRQ_DATA(9)
NAME
struct_irq_data - per irq and irq chip data passed down to chip functions
SYNOPSIS
struct irq_data {
unsigned int irq;
unsigned long hwirq;
unsigned int node;
unsigned int state_use_accessors;
struct irq_chip * chip;
struct irq_domain * domain;
void * handler_data;
void * chip_data;
struct msi_desc * msi_desc;
cpumask_var_t affinity;
};
MEMBERS
irq
interrupt number
hwirq
hardware interrupt number, local to the interrupt domain
node
node index useful for balancing
state_use_accessors
status information for irq chip functions. Use accessor functions to deal with it
chip
low level interrupt hardware access
domain
Interrupt translation domain; responsible for mapping between hwirq number and linux irq number.
handler_data
per-IRQ data for the irq_chip methods
chip_data
platform-specific per-chip private data for the chip methods, to allow shared chip implementations
msi_desc
MSI descriptor
affinity
IRQ affinity on SMP
DESCRIPTION
The fields here need to overlay the ones in irq_desc until we cleaned up the direct references and switched everything over to irq_data.
