Name:mp_check_pin_attr
Proto:static bool mp_check_pin_attr(int irq, struct irq_alloc_info *info)
Type:bool
Parameter:
| Type | Parameter | Name |
|---|---|---|
| int | irq | |
| struct irq_alloc_info * | info |
| 941 | data = irq_get_chip_data(irq) |
| 948 | If irq < nr_legacy_irqs() && count == 1 Then |
| 949 | If ioapic_trigger != trigger Then mp_register_handler(irq, ioapic_trigger) |
| 951 | 0: edge, 1: level = trigger = ioapic_trigger |
| 952 | polarity = polarity = ioapic_polarity |
| 955 | Return trigger == ioapic_trigger && polarity == ioapic_polarity |
| Name | Describe |
|---|---|
| alloc_isa_irq_from_domain | Need special handling for ISA IRQs because there may be multiple IOAPIC pins* sharing the same ISA IRQ number and irqdomain only supports 1:1 mapping* between IOAPIC pin and IRQ number. A typical IOAPIC has 24 pins, pin 0-15 are |
