Name

struct irq_common_data — per irq data shared by all irqchips

Synopsis

struct irq_common_data {
  unsigned int __private state_use_accessors;
#ifdef CONFIG_NUMA
  unsigned int node;
#endif
  void * handler_data;
  struct msi_desc * msi_desc;
  cpumask_var_t affinity;
#ifdef CONFIG_GENERIC_IRQ_IPI
  unsigned int ipi_offset;
#endif
};

Members

unsigned int __private state_use_accessors: status information for irq chip functions. Use accessor functions to deal with it
unsigned int node: node index useful for balancing
void * handler_data: per-IRQ data for the irq_chip methods
struct msi_desc * msi_desc: MSI descriptor
cpumask_var_t affinity: IRQ affinity on SMP. If this is an IPI related irq, then this is the mask of the CPUs to which an IPI can be sent.
unsigned int ipi_offset: Offset of first IPI target cpu in affinity. Optional.
