NameDescribe
irq_set_vcpu_affinityq_set_vcpu_affinity - Set vcpu affinity for the interrupt*@irq: interrupt number to set affinity*@vcpu_info: vCPU specific data or pointer to a percpu array of vCPU* specific data for percpu_devid interrupts* This function uses the vCPU specific data to
can_request_irqInternal function that tells the architecture code whether a* particular irq has been exclusively allocated or is available* for driver use.
enable_percpu_irq
irq_percpu_is_enabledq_percpu_is_enabled - Check whether the per cpu irq is enabled*@irq: Linux irq number to check for* Must be called from a non migratable context. Returns the enable* state of a per cpu interrupt on the current cpu.
disable_percpu_irq
prepare_percpu_nmiprepare_percpu_nmi - performs CPU local setup for NMI delivery*@irq: Interrupt line to prepare for NMI delivery* This call prepares an interrupt line to deliver NMI on the current CPU,* before that interrupt line gets enabled with enable_percpu_nmi()
teardown_percpu_nmiardown_percpu_nmi - undoes NMI setup of IRQ line*@irq: Interrupt line from which CPU local NMI configuration should be* removed* This call undoes the setup done by prepare_percpu_nmi()
irq_set_chipq_set_chip - set the irq chip for an irq*@irq: irq number*@chip: pointer to irq chip description structure
irq_set_handler_dataq_set_handler_data - set irq handler data for an irq*@irq: Interrupt number*@data: Pointer to interrupt specific data* Set the hardware irq controller data for an irq
irq_set_msi_desc_offq_set_msi_desc_off - set MSI descriptor data for an irq at offset*@irq_base: Interrupt number base*@irq_offset: Interrupt number offset*@entry: Pointer to MSI descriptor data* Set the MSI descriptor entry for an irq at offset
irq_set_chip_dataq_set_chip_data - set irq chip data for an irq*@irq: Interrupt number*@data: Pointer to chip specific data* Set the hardware irq chip data for an irq
