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) dip Pointer to dev_info structure typesp Pointer to supported interrupt types 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 hardware interrupts. 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. See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ pci(4), attributes(5), pcmcia(7D), sysbus(4), ddi_intr_add_handler(9F), ddi_intr_alloc(9F), ddi_intr_enable(9F) 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 han- dler for a given interrupt type. Soft interrupts are always usable and are not returned by this interface. 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. 07 Apr 2005 ddi_intr_get_supported_types(9F)
