lapic_assign_system_vectors

Name:lapic_assign_system_vectors

Proto:void __init lapic_assign_system_vectors(void)

Type:void

Parameter:Nothing

679

vector = 0

681

same as for_each_set_bit() but use bit as value to start with (vector, system_vectors, NR_VECTORS)

682

irq_matrix_assign_system(vector_matrix, vector, false)

684

If nr_legacy_irqs() > 1 Then lapic_assign_legacy_vector(8259A PIC related value , false)

688

irq_matrix_online(vector_matrix)

691

When i < nr_legacy_irqs() cycle

692

If i != 8259A PIC related value Then irq_matrix_assign(vector_matrix, Vectors 0x30-0x3f are used for ISA interrupts.* round up to the next 16-vector boundary(i))
