unsigned int __private state_use_accessors
.RS 4
status information for irq chip functions\&. Use accessor functions to deal with it
.RE
.PP
unsigned int node
.RS 4
node index useful for balancing
.RE
.PP
void * handler_data
.RS 4
per\-IRQ data for the irq_chip methods
.RE
.PP
struct msi_desc * msi_desc
.RS 4
MSI descriptor

cpumask_var_t affinity
.RS 4
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\&.
.RE
.PP
unsigned int ipi_offset
.RS 4
Offset of first IPI target cpu in
\fIaffinity\fR\&. Optional\&.
