 241  * The DATA flags specify the type of data provided.  If DATA_NONE, the

 244  * flags = (DATA_NONE|ACTION_UNMASK), index = 0, start = 0, count = 1.
 245  *
 246  * DATA_BOOL allows sparse support for the same on arrays of interrupts.
 247  * For example, to mask interrupts [0,1] and [0,3] (but not [0,2]):
 248  * flags = (DATA_BOOL|ACTION_MASK), index = 0, start = 1, count = 3,
 249  * data = {1,0,1}

 255  * flags = (DATA_EVENTFD|ACTION_TRIGGER), index = 0, start = 0, count = 3,

 257  * If index [0,1] is previously set, two count = 1 ioctls calls would be
 258  * required to set [0,0] and [0,2] without changing [0,1].
 259  *
 260  * Once a signaling mechanism is set, DATA_BOOL or DATA_NONE can be used

 262  * from userspace (ie. simulate hardware triggering).
 263  *
 264  * Setting of an event triggering mechanism to userspace for ACTION_TRIGGER
 265  * enables the interrupt index for the device.  Individual subindex interrupts
 266  * can be disabled using the -1 value for DATA_EVENTFD or the index can be
 267  * disabled as a whole with: flags = (DATA_NONE|ACTION_TRIGGER), count = 0.
