NAME
ddi_intr_get_pending - get pending bit for a given interrupt SYNOPSIS
#include <sys/types.h> #include <sys/conf.h> #include <sys/ddi.h> #include <sys/sunddi.h> int ddi_intr_get_pending(ddi_intr_handle_t h, int *pendingp); INTERFACE LEVEL
Solaris DDI specific (Solaris DDI). h DDI interrupt handle pendingp Pointer to the pending capability returned for this handle The ddi_intr_get_pending() function returns non-zero as the integer pointed to by the pendingp argument if a corresponding interrupt is pending. The corresponding interrupt handle h must already be allocated. The call succeeds if the device or host bridge supports the abil- ity to read the interrupt pending bits of its interrupts. The driver should use ddi_intr_get_cap() function to see if the DDI_INTR_FLAG_PENDING flag is returned to indicate that interrupts support interrupt pending bits. If the DDI_INTR_FLAG_PENDING capability is not supported, ddi_intr_get_pending() returns DDI_ENOTSUP and zero in pendingp. The ddi_intr_get_pending() function returns: DDI_SUCCESS On success. DDI_EINVAL On encountering invalid input parameters. DDI_FAILURE On any implementation specific failure. DDI_ENOTSUP On device not supporting operation. CONTEXT
The ddi_intr_get_pending() function can be called from either user or kernel non-interrupt context. See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ attributes(5), ddi_intr_block_enable(9F), ddi_intr_block_disable(9F), ddi_intr_clr_mask(9F), ddi_intr_disable(9F), ddi_intr_enable(9F), ddi_intr_set_mask(9F) 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. 07Apr 2005 ddi_intr_get_pending(9F)
