Find the interrupt vector associated with a device
#include <drvr/hwinfo.h> unsigned hwitag_find_ivec( unsigned hwi_off, unsigned *irq );
libdrvr
Use the -l drvr option to qcc to link against this library.
You can use hwitag_find_ivec() to find one or more interrupt vectors associated with the device at hwi_off in the hwinfo section of the system page. You can get the hwi_off parameter by calling hwi_find_device().
Some devices contain multiple interrupt vectors. You can retrieve all of them by using the ivec_idx parameter as follows:
The interrupt vector, or HWI_ILLEGAL_VECTOR if the vector isn't found.
