563 *
564 * The %FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE ioctl initiates allocation of an
565 * isochronous channel and/or of isochronous bandwidth at the isochronous
566 * resource manager (IRM). Only one of the channels specified in @channels is
567 * allocated. An %FW_CDEV_EVENT_ISO_RESOURCE_ALLOCATED is sent after
568 * communication with the IRM, indicating success or failure in the event data.
569 * The kernel will automatically reallocate the resources after bus resets.
570 * Should a reallocation fail, an %FW_CDEV_EVENT_ISO_RESOURCE_DEALLOCATED event
571 * will be sent. The kernel will also automatically deallocate the resources
572 * when the file descriptor is closed.
573 *
574 * The %FW_CDEV_IOC_DEALLOCATE_ISO_RESOURCE ioctl can be used to initiate
575 * deallocation of resources which were allocated as described above.
576 * An %FW_CDEV_EVENT_ISO_RESOURCE_DEALLOCATED event concludes this operation.

578 * The %FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE_ONCE ioctl is a variant of allocation
579 * without automatic re- or deallocation.
580 * An %FW_CDEV_EVENT_ISO_RESOURCE_ALLOCATED event concludes this operation,
581 * indicating success or failure in its data.
582 *
583 * The %FW_CDEV_IOC_DEALLOCATE_ISO_RESOURCE_ONCE ioctl works like
584 * %FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE_ONCE except that resources are freed

586 * An %FW_CDEV_EVENT_ISO_RESOURCE_DEALLOCATED event concludes this operation.
587 *
588 * To summarize, %FW_CDEV_IOC_DEALLOCATE_ISO_RESOURCE allocates iso resources
589 * for the lifetime of the fd or handle.
590 * In contrast, %FW_CDEV_IOC_ALLOCATE_ISO_RESOURCE_ONCE allocates iso resources
591 * for the duration of a bus generation.

594 * representing channel 0 and the most significant bit representing channel 63:
595 * 1ULL << c for each channel c that is a candidate for (de)allocation.
