DDI_INTR_GET_SUPPORTED_TYPES(9F)	      DDI_INTR_GET_SUPPORTED_TYPES(9F)

NAME
       ddi_intr_get_supported_types - return information on supported hardware
       interrupt types

SYNOPSIS
       #include <sys/types.h>
       #include <sys/conf.h>
       #include <sys/ddi.h>
       #include <sys/sunddi.h>

       int ddi_intr_get_supported_types(dev_info_t *dip, int *typesp);

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI)

PARAMETERS
       dip
		 Pointer to dev_info structure

       typesp
		 Pointer to supported interrupt types

DESCRIPTION
       The ddi_intr_get_supported_types()  function  retrieves	the  interrupt
       types supported by a particular hardware device and by the system soft‐
       ware. Upon successful return, the supported types are returned as a bit
       mask   in   the	 integer  pointed  to  by  the	typesp	argument.  See
       <sys/ddi_intr.h> for a list of interrupts that can  be  returned	 by  a
       hardware device.

       For  PCI	 devices  that	support	 MSI and/or MSI-X based hardware, this
       interface returns only the interrupt types that are  supported  by  all
       the hardware in the path to the hardware device.

       An interrupt type is usable by the hardware device if it is returned by
       the ddi_intr_get_supported_types() function. The device driver  can  be
       programmed  to use one of the returned interrupt types to receive hard‐
       ware interrupts.

RETURN VALUES
       The ddi_intr_get_supported_types() function returns:

       DDI_SUCCESS
			    On success.

       DDI_EINVAL
			    On encountering invalid input parameters.

       DDI_INTR_NOTFOUND
			    Returned when the hardware device is found not  to
			    support any hardware interrupts.

CONTEXT
       The  ddi_intr_get_supported_types() function can be called from user or
       kernel non-interrupt context.

       Writing Device Drivers

NOTES
       The ddi_intr_get_supported_types() function can be called by the device
       driver even at any time if the driver has added	an  interrupt  handler
       for a given interrupt type.

       Soft  interrupts	 are always usable and are not returned by this inter‐
       face.

       Any consumer of this interface should verify that the return  value  is
       not  equal  to DDI_SUCCESS. Incomplete checking for failure codes could
       result in inconsistent behavior among platforms.
