MIPS AU1XXX IDE driver
======================
Released 2005-07-15
About
=====
This file describes the 'drivers/ide/au1xxx-ide.c', related files and the
services they provide.
If you are short in patience and just want to know how to add your hard disc to
the white or black list, go to the 'ADD NEW HARD DISC TO WHITE OR BLACK LIST'

Interface and Linux Device Driver" Application Note.
Files, Configs and Compatibility
================================
Two files are introduced:
a) 'arch/mips/include/asm/mach-au1x00/au1xxx_ide.h'
contains : struct _auide_hwif
- timing parameters for PIO mode 0/1/2/3/4
- timing parameters for MWDMA 0/1/2
b) 'drivers/ide/mips/au1xxx-ide.c'
contains the functionality of the AU1XXX IDE driver
Following extra configs variables are introduced:
CONFIG_BLK_DEV_IDE_AU1XXX_PIO_DBDMA
- enable the PIO+DBDMA mode
CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA
- enable the MWDMA mode
Supported IDE Modes
===================
The AU1XXX IDE driver supported all PIO modes - PIO mode 0/1/2/3/4 - and all
MWDMA modes - MWDMA 0/1/2 -. There is no support for SWDMA and UDMA mode.
To change the PIO mode use the program hdparm with option -p, e.g.
'hdparm -p0 [device]' for PIO mode 0. To enable the MWDMA mode use the option
-X, e.g. 'hdparm -X32 [device]' for MWDMA mode 0.
Performance Configurations
==========================
If the used system doesn't need USB support enable the following kernel
configs::
CONFIG_IDE=y
CONFIG_BLK_DEV_IDE=y
CONFIG_IDE_GENERIC=y
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_BLK_DEV_GENERIC=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
CONFIG_BLK_DEV_IDE_AU1XXX=y
CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA=y
CONFIG_BLK_DEV_IDEDMA=y
Also define 'IDE_AU1XXX_BURSTMODE' in 'drivers/ide/mips/au1xxx-ide.c' to enable
the burst support on DBDMA controller.
If the used system need the USB support enable the following kernel configs for
high IDE to USB throughput.
::
CONFIG_IDE_GENERIC=y
CONFIG_BLK_DEV_IDEPCI=y
CONFIG_BLK_DEV_GENERIC=y
CONFIG_BLK_DEV_IDEDMA_PCI=y
CONFIG_BLK_DEV_IDE_AU1XXX=y
CONFIG_BLK_DEV_IDE_AU1XXX_MDMA2_DBDMA=y
CONFIG_BLK_DEV_IDEDMA=y
Also undefine 'IDE_AU1XXX_BURSTMODE' in 'drivers/ide/mips/au1xxx-ide.c' to
disable the burst support on DBDMA controller.
Acknowledgments
===============
These drivers wouldn't have been done without the base of kernel 2.4.x AU1XXX
IDE driver from AMD.
Additional input also from:
Matthias Lenk <matthias.lenk@amd.com>
Happy hacking!
Enrico Walther <enrico.walther@amd.com>
