1458 * The debugger specifies the size of the array allocated in @num_queues.
1459 * KFD returns the number of queues that actually existed. If this is
1460 * larger than the size specified by the debugger, KFD will not overflow
1461 * the array allocated by the debugger.
1462 *
1463 * @entry_size (IN/OUT) - size per entry in bytes
1464 * The debugger specifies sizeof(struct kfd_queue_snapshot_entry) in
1465 * @entry_size. KFD returns the number of bytes actually populated per
1466 * entry. The debugger should use the KFD_IOCTL_MINOR_VERSION to determine,
1467 * which fields in struct kfd_queue_snapshot_entry are valid. This allows
1468 * growing the ABI in a backwards compatible manner.
1469 * Note that entry_size(IN) should still be used to stride the snapshot buffer in the
1470 * event that it's larger than actual kfd_queue_snapshot_entry.
1471 *
1472 * Generic errors apply (see kfd_dbg_trap_operations).
