This is a major rework of the ATA driver (ATAng)

2003-08-24T09:22:26Z

Restructure the way ATA/ATAPI commands are processed, use a common ata_request structure for both. This centralises the way requests are handled so locking is much easier to handle. The driver is now layered much more cleanly to seperate the lowlevel HW access so it can be tailored to specific controllers without touching the upper layers. This is needed to support some of the newer semi-intelligent ATA controllers showing up. The top level drivers (disk, ATAPI devices) are more or less still the same with just corrections to use the new interface. Pull ATA out from under Gaint now that locking can be done in a sane way. Add support for a the National Geode SC1100. Thanks to Soekris engineering for sponsoring a Soekris 4801 to make this support. Fixed alot of small bugs in the chipset code for various chips now we are around in that corner anyways.

Second round of updates to the ATA driver.

Clean up the DMA interface too much unneeded stuff crept in with the busdma code back when. Modify the ATA_IN* / ATA_OUT* macros so that resource and offset are gotten from a table. That allows for new chipsets that doesn't nessesarily have things ordered the good old way. This also removes the need for the wierd PC98 resource functions. Tested on: i386, PC98, Alpha, Sparc64

Dont call dma->free unless dma is there.

Always set the setmode funcptr.

More low-hanging fruit: kill caddr_t in calls to wakeup(9) / [mt]sleep(9).

First round off updates/fixes to the ATA driver.

2003-02-20T20:02:32Z

This moves all chipset specific code to a new file 'ata-chipset.c'. Extensive use of tables and pointers to avoid having the same switch on chipset type in several places, and to allow substituting various functions for different HW arch needs. Added PIO mode setup and all DMA modes. Support for all known SiS chipsets. Thanks to Christoph Kukulies for sponsoring a nice ASUS P4S8X SiS648 based board for this work! Tested on: i386, PC98, alpha and sparc64

Fix an indentation problem.

Dont hang in atprq on poll_dsc command.

This is a temporary fix until I get proper locking done. Submitted by: iedowse@maths.tcd.ie

Fix buffer length.

PR: 41063

Add the ability to use ATAPI devices via CAM.

2002-08-09T20:54:06Z

The CAM<>ATAPI layer was submitted by "Thomas Quinot " changes form the version on the net by me (formatting, ability to be used alone without the ATAPI native device driver, proper speed reporting...) See /sys/conf/NOTES for usage. Submitted by: Thomas Quinot
