hv_gic_config_set_msi_interrupt_range(_:_:_:)

Sets the range of message signaled interrupts (MSIs) the generic interrupt controller supports.

Declaration

func hv_gic_config_set_msi_interrupt_range(_ config: hv_gic_config_t, _ msi_intid_base: UInt32, _ msi_intid_count: UInt32) -> hv_return_t

Parameters

  • config:

    A generic interrupt controller (GIC) configuration object.

  • msi_intid_base:

    The lowest MSI interrupt number.

  • msi_intid_count:

    Number of message signaled interrupts.

Return Value

HV_SUCCESS on success; otherwise, an error code.

Discussion

Use this method to configure the range of identifiers supported for MSIs. If it’s outside of the range given by hv_gic_get_spi_interrupt_range(_:_:), the method returns an error.

Set the region base address with hv_gic_config_set_msi_region_base(_:_:).
