ddi_intr_clr_mask(9f)

ddi_intr_set_mask(9F)          Kernel Functions          ddi_intr_set_mask(9F)

NAME
       ddi_intr_set_mask,  ddi_intr_clr_mask  -  set or clear mask for a given
       interrupt

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

       int ddi_intr_set_mask(ddi_intr_handle_t h);


       int ddi_intr_clr_mask(ddi_intr_handle_t h);

INTERFACE LEVEL
       Solaris DDI specific (Solaris DDI).

PARAMETERS
       h    DDI interrupt handle


DESCRIPTION
       The ddi_intr_set_mask() function masks the given interrupt  pointed  to
       by  the  device's  interrupt handle h if the device or host bridge sup‐
       ports the masking operation. The  ddi_intr_get_cap()  function  returns
       the  RO  flag  DDI_INTR_FLAG_MASKABLE if the device or host bridge sup‐
       ports interrupt mask bits for the given interrupt type. In  flight  in‐
       terrupts can still be taken and delivered to the driver.


       The ddi_intr_clr_mask() function unmasks the given interrupt pointed by
       the  device's  interrupt handle h if the device or host bridge supports
       the masking operation.


       The ddi_intr_set_mask() and  ddi_intr_clr_mask()  functions  should  be
       called  only  if  an interrupt is enabled. Otherwise the framework will
       return DDI_EINVAL to such calls.


       The mask cannot be cleared directly if the OS implementation  has  also
       temporarily masked the interrupt. A call to ddi_intr_clr_mask() must be
       preceded  by a call to ddi_intr_set_mask(). It is not necessary to call
       ddi_intr_clr_mask() when adding and enabling the interrupt.

RETURN VALUES
       The ddi_intr_set_mask() and ddi_intr_clr_mask() functions return:

       DDI_SUCCESS    On success.


       DDI_EINVAL     On encountering invalid input parameters or when an  in‐
                      terrupt is not enabled.


       DDI_FAILURE    On any implementation specific failure.


       DDI_ENOTSUP    On device not supporting operation.


CONTEXT
       The ddi_intr_set_mask() and ddi_intr_clr_mask() functions can be called
       from any context.

NOTES
       Consumers  of  these  interfaces should verify that the return value is
       not equal to DDI_SUCCESS. Incomplete checking for failure  codes  could
       result in inconsistent behavior among platforms.
