-IDE ATAPI streaming tape driver
--------------------------------
-
-This driver is a part of the Linux ide driver and works in co-operation
-with linux/drivers/block/ide.c.
-
-The driver, in co-operation with ide.c, basically traverses the
-request-list for the block device interface. The character device
-interface, on the other hand, creates new requests, adds them
-to the request-list of the block device, and waits for their completion.
-
-Pipelined operation mode is now supported on both reads and writes.
-
-The block device major and minor numbers are determined from the
-tape's relative position in the ide interfaces, as explained in ide.c.
-
-The character device interface consists of the following devices:
-
- ht0 major 37, minor 0 first IDE tape, rewind on close.
- ht1 major 37, minor 1 second IDE tape, rewind on close.
- ...
- nht0 major 37, minor 128 first IDE tape, no rewind on close.
- nht1 major 37, minor 129 second IDE tape, no rewind on close.
- ...
-
-Run /dev/MAKEDEV to create the above entries.
-
-The general magnetic tape commands compatible interface, as defined by
-include/linux/mtio.h, is accessible through the character device.
-
-General ide driver configuration options, such as the interrupt-unmask
-flag, can be configured by issuing an ioctl to the block device interface,
-as any other ide device.
-
-Our own ide-tape ioctl's can be issued to either the block device or
-the character device interface.
-
-Maximal throughput with minimal bus load will usually be achieved in the
-following scenario:
-
- 1. ide-tape is operating in the pipelined operation mode.
- 2. No buffering is performed by the user backup program.

- * This module provides support for the bus-master IDE DMA functions

- * DMA is supported for all IDE devices (disk drives, cdroms, tapes, floppies).
- *
- * By default, DMA support is prepared for use, but is currently enabled only
- * for drives which already have DMA enabled (UltraDMA or mode 2 multi/single),
- * or which are recognized as "good" (see table below). Drives with only mode0
- * or mode1 (multi/single) DMA should also work with this chipset/driver
- * (eg. MC2112A) but are not enabled by default.
- *
- * Use "hdparm -i" to view modes supported by a given drive.
- *
- * The hdparm-3.5 (or later) utility can be used for manually enabling/disabling
- * DMA support, but must be (re-)compiled against this kernel version or later.
- *
- * To enable DMA, use "hdparm -d1 /dev/hd?" on a per-drive basis after booting.
- * If problems arise, ide.c will disable DMA operation after a few retries.
- * This error recovery mechanism works and has been extremely well exercised.
- *
- * IDE drives, depending on their vintage, may support several different modes
- * of DMA operation. The boot-time modes are indicated with a "*" in
- * the "hdparm -i" listing, and can be changed with *knowledgeable* use of
- * the "hdparm -X" feature. There is seldom a need to do this, as drives
- * normally power-up with their "best" PIO/DMA modes enabled.
- *
- * Testing has been done with a rather extensive number of drives,
- * with Quantum & Western Digital models generally outperforming the pack,
- * and Fujitsu & Conner (and some Seagate which are really Conner) drives
- * showing more lackluster throughput.
