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. AUTHORS
