- * This module provides support for the bus-master IDE DMA functions
- * of various PCI chipsets, including the Intel PIIX (i82371FB for
- * the 430 FX chipset), the PIIX3 (i82371SB for the 430 HX/VX and
- * 440 chipsets), and the PIIX4 (i82371AB for the 430 TX chipset)
- * ("PIIX" stands for "PCI ISA IDE Xcellerator").
- *
- * Pretty much the same code works for other IDE PCI bus-mastering chipsets.
- *
- * 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.
- *
- * Keep an eye on /var/adm/messages for "DMA disabled" messages.

- * Some people have reported trouble with Intel Zappa motherboards.
