310IDE ATAPI streaming tape driver
311-------------------------------
312
313This driver is a part of the Linux ide driver and works in co-operation
314with linux/drivers/block/ide.c.
315
316The driver, in co-operation with ide.c, basically traverses the
317request-list for the block device interface. The character device
318interface, on the other hand, creates new requests, adds them
319to the request-list of the block device, and waits for their completion.
320
321Pipelined operation mode is now supported on both reads and writes.
322
323The block device major and minor numbers are determined from the
324tape's relative position in the ide interfaces, as explained in ide.c.
325
326The character device interface consists of the following devices:
327
328 ht0 major 37, minor 0 first IDE tape, rewind on close.
329 ht1 major 37, minor 1 second IDE tape, rewind on close.
330 ...
331 nht0 major 37, minor 128 first IDE tape, no rewind on close.
332 nht1 major 37, minor 129 second IDE tape, no rewind on close.
333 ...
334
335Run /dev/MAKEDEV to create the above entries.
336
337The general magnetic tape commands compatible interface, as defined by
338include/linux/mtio.h, is accessible through the character device.
339
340General ide driver configuration options, such as the interrupt-unmask
341flag, can be configured by issuing an ioctl to the block device interface,
342as any other ide device.
343
344Our own ide-tape ioctl's can be issued to either the block device or
345the character device interface.
346
347Maximal throughput with minimal bus load will usually be achieved in the
348following scenario:
349
350 1. ide-tape is operating in the pipelined operation mode.
351 2. No buffering is performed by the user backup program.
