ipi_send

Name:pi_send_mask - Send an IPI to target CPU(s)*@virq: linux irq number from irq_reserve_ipi()*@dest: dest CPU(s), must be a subset of the mask passed to* irq_reserve_ipi()* Returns zero on success and negative error number on failure.

Proto:int ipi_send_mask(unsigned int virq, const struct cpumask *dest)

Type:int

Parameter:

Type	Parameter	Name
unsigned int	virq
const struct cpumask *	dest

desc = Interrupt to descriptor

struct irq_data * data = desc ? irq_desc_get_irq_data(desc) : NULL

If WARN_ON_ONCE(ipi_send_verify(chip, data, dest, 0)) Then Return -EINVAL
