++ * The NORESIZE flag indicates that the interrupt lines within the index

++ * disabling the entire index. This is used for interrupts like PCI MSI
++ * and MSI-X where the driver may only use a subset of the available
++ * indexes, but VFIO needs to enable a specific number of vectors
++ * upfront. In the case of MSI-X, where the user can enable MSI-X and
++ * then add and unmask vectors, it's up to userspace to make the decision
++ * whether to allocate the maximum supported number of vectors or tear
++ * down setup and incrementally increase the vectors as each is enabled.

++ * the range of subindexes being specified.
++ *
++ * The DATA flags specify the type of data provided. If DATA_NONE, the
++ * operation performs the specified action immediately on the specified
++ * interrupt(s). For example, to unmask AUTOMASKED interrupt [0,0]:
++ * flags = (DATA_NONE|ACTION_UNMASK), index = 0, start = 0, count = 1.
++ *
++ * DATA_BOOL allows sparse support for the same on arrays of interrupts.
++ * For example, to mask interrupts [0,1] and [0,3] (but not [0,2]):
++ * flags = (DATA_BOOL|ACTION_MASK), index = 0, start = 1, count = 3,
++ * data = {1,0,1}
++ *
++ * DATA_EVENTFD binds the specified ACTION to the provided __s32 eventfd.
++ * A value of -1 can be used to either de-assign interrupts if already
++ * assigned or skip un-assigned interrupts. For example, to set an eventfd
++ * to be trigger for interrupts [0,0] and [0,2]:
++ * flags = (DATA_EVENTFD|ACTION_TRIGGER), index = 0, start = 0, count = 3,
++ * data = {fd1, -1, fd2}
++ * If index [0,1] is previously set, two count = 1 ioctls calls would be
++ * required to set [0,0] and [0,2] without changing [0,1].
++ *
++ * Once a signaling mechanism is set, DATA_BOOL or DATA_NONE can be used
++ * with ACTION_TRIGGER to perform kernel level interrupt loopback testing
++ * from userspace (ie. simulate hardware triggering).
++ *
++ * Setting of an event triggering mechanism to userspace for ACTION_TRIGGER
++ * enables the interrupt index for the device. Individual subindex interrupts
++ * can be disabled using the -1 value for DATA_EVENTFD or the index can be
++ * disabled as a whole with: flags = (DATA_NONE|ACTION_TRIGGER), count = 0.
++ *
++ * Note that ACTION_[UN]MASK specify user->kernel signaling (irqfds) while
++ * ACTION_TRIGGER specifies kernel->user signaling.
