ddi_intr_set_mask(9F)													     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). h DDI interrupt handle 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 interrupts 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 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. 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. The system framework will clear any device or host bridge mask bits when the interrupt is initially enabled. The ddi_intr_set_mask() and ddi_intr_clr_mask() functions return: 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_set_mask() and ddi_intr_clr_mask() functions can be called from any context. See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Evolving | +-----------------------------+-----------------------------+ attributes(5), ddi_intr_block_disable(9F), ddi_intr_block_enable(9F), ddi_intr_disable(9F), ddi_intr_enable(9F), ddi_intr_get_pending(9F) 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. 22 Apri 2005 ddi_intr_set_mask(9F)
