Fourth update to the new ATA/ATAPI driver: Well, better late than newer, but things has been hectic around here, sorry for the long delay. DMA support has been added to the ATA disk driver. This only works on Intel PIIX3/4, Acer Aladdin and Promise controllers. The promise support works without the BIOS on the board, and timing modes are set to support up to UDMA speed. This solves the problems with having more than one promise controller in the same system. There is support for "generic" DMA, that might work on other controllers, but now you have been warned :) More chipset specific code will come soon, I have to find testers with the approbiate HW, more on that when I have it ready. The system now uses its own major numbers, please run MAKEDEV with the devices you need (ad?, acd?, afd?, ast?). For now the disk driver will also attach to the old wd major so one can at least boot without this step, but be warned, this will eventually go away. The bootblocks will have to be changed before one can boot directly from an "ad" device though. Fixed problems: All known hang problems should be solved The probe code has been sligthly changed, this should solve the reports I have lying around (I hope). Hangs when accessing ata & atapi device on the same channel simultaniously. A real braino in ata_start caused this, fixed. As usual USE AT YOUR OWN RISK!!, this is still pre alpha level code. Especially the DMA support can hose your disk real bad if anything goes wrong, agaiin you have been warned :) But please tell me how it works for you! Enjoy! -Søren

Support DMA on ATAPI devices (finally). This makes my system use only ~5% CPU on reading 4.5Mbyte/sec from a CDROM, which before was limitted to 1.8Mbyte/sec due to 100% CPU load..

It works now both on LS120 & ZIP drives. ISA only configs wont compile. Fixed. The ATA driver wont share interrupts. Fixed. The "unwanted interrupt" warning gave wrong controller.

Bring the 'new-bus' to the i386. This extensively changes the way the i386 platform boots, it is no longer ISA-centric, and is fully dynamic. Most old drivers compile and run without modification via 'compatability shims' to enable a smoother transition. eisa, isapnp and pccard* are not yet using the new resource manager. Once fully converted, all drivers will be loadable, including PCI and ISA. (Some other changes appear to have snuck in, including a port of Soren's ATA driver to the Alpha. Soren, back this out if you need to.) This is a checkpoint of work-in-progress, but is quite functional. The bulk of the work was done over the last few years by Doug Rabson and Garrett Wollman.

Seventh update to the new ATA/ATAPI driver: Fixed problems: LS120 drives currupted data. The workaround for drives not supporting upto 64K transfers has been reworked. It works now both on LS120 & ZIP drives. ISA only configs wont compile. Fixed. The ATA driver wont share interrupts. Fixed. The "unwanted interrupt" warning gave wrong controller. Another lun<>unit messup from the newbus integration. Some minor cleanups and rearrangements as well. As usual USE AT YOUR OWN RISK!!, this is still pre alpha level code. Especially the DMA support can hose your disk real bad if anything goes wrong, again you have been warned :) Notebook owners should be carefull that their machines dont suspend as this might cause trouble...

Fourth update to the new ATA/ATAPI driver: Well, better late than newer, but things has been hectic around here, sorry for the long delay. DMA support has been added to the ATA disk driver. This only works on Intel PIIX3/4, Acer Aladdin and Promise controllers. The promise support works without the BIOS on the board, and timing modes are set to support up to UDMA speed. This solves the problems with having more than one promise controller in the same system. There is support for "generic" DMA, that might work on other controllers, but now you have been warned :) More chipset specific code will come soon, I have to find testers with the approbiate HW, more on that when I have it ready. The system now uses its own major numbers, please run MAKEDEV with the devices you need (ad?, acd?, afd?, ast?). For now the disk driver will also attach to the old wd major so one can at least boot without this step, but be warned, this will eventually go away. The bootblocks will have to be changed before one can boot directly from an "ad" device though. Fixed problems: All known hang problems should be solved The probe code has been sligthly changed, this should solve the reports I have lying around (I hope). Hangs when accessing ata & atapi device on the same channel simultaniously. A real braino in ata_start caused this, fixed. As usual USE AT YOUR OWN RISK!!, this is still pre alpha level code.

Bring the 'new-bus' to the i386. This extensively changes the way the i386 platform boots, it is no longer ISA-centric, and is fully dynamic. Most old drivers compile and run without modification via 'compatability shims' to enable a smoother transition. eisa, isapnp and pccard* are not yet using the new resource manager. Once fully converted, all drivers will be loadable, including PCI and ISA. (Some other changes appear to have snuck in, including a port of Soren's ATA driver to the Alpha. Soren, back this out if you need to.) This is a checkpoint of work-in-progress, but is quite functional. The bulk of the work was done over the last few years by Doug Rabson and Garrett Wollman.
