Support is working on some AHCI chips but far from all. Remember this is WIP, so test reports and (constructive) suggestions are welcome! 2007-02-21T19:07:19Z Søren Schmidt sos@FreeBSD.org 2007-02-21T19:07:19Z urn:sha1:129230b81602d3e4fcc2ae4e0eef002dad24978e 2006-01-05T21:27:19Z Søren Schmidt sos@FreeBSD.org 2006-01-05T21:27:19Z urn:sha1:e2bf77c5c202b5e570101e4c918a96f402242a5c 2005-03-30T12:03:40Z Søren Schmidt sos@FreeBSD.org 2005-03-30T12:03:40Z urn:sha1:8ca4df3299628bad609cb74ee2f76671e07b4788 o ATA is now fully newbus'd and split into modules. This means that on a modern system you just load "atapci and ata" to get the base support, and then one or more of the device subdrivers "atadisk atapicd atapifd atapist ataraid". All can be loaded/unloaded anytime, but for obvious reasons you dont want to unload atadisk when you have mounted filesystems. o The device identify part of the probe has been rewritten to fix the problems with odd devices the old had, and to try to remove so of the long delays some HW could provoke. Also probing is done without the need for interrupts, making earlier probing possible. o SATA devices can be hot inserted/removed and devices will be created/ removed in /dev accordingly. NOTE: only supported on controllers that has this feature: Promise and Silicon Image for now. On other controllers the usual atacontrol detach/attach dance is still needed. o Support for "atomic" composite ATA requests used for RAID. o ATA RAID support has been rewritten and and now supports these metadata formats: "Adaptec HostRAID" "Highpoint V2 RocketRAID" "Highpoint V3 RocketRAID" "Intel MatrixRAID" "Integrated Technology Express" "LSILogic V2 MegaRAID" "LSILogic V3 MegaRAID" "Promise FastTrak" "Silicon Image Medley" "FreeBSD PseudoRAID" o Update the ioctl API to match new RAID levels etc. o Update atacontrol to know about the new RAID levels etc NOTE: you need to recompile atacontrol with the new sys/ata.h, make world will take care of that. NOTE2: that rebuild is done differently from the old system as the rebuild is now done piggybacked on read requests to the array, so atacontrol simply starts a background "dd" to rebuild the array. o The reinit code has been worked over to be much more robust. o The timeout code has been overhauled for races. o Support of new chipsets. o Lots of fixes for bugs found while doing the modulerization and reviewing the old code. Missing or changed features from current ATA: o atapi-cd no longer has support for ATAPI changers. Todays its much cheaper and alot faster to copy those CD images to disk and serve them from there. Besides they dont seem to be made anymore, maybe for that exact reason. o ATA RAID can only read metadata from all the above metadata formats, not write all of them (Promise and Highpoint V2 so far). This means that arrays can be picked up from the BIOS, but they cannot be created from FreeBSD. There is more to it than just the missing write metadata support, those formats are not unique to a given controller like Promise and Highpoint formats, instead they exist for several types, and even worse, some controllers can have different formats and its impossible to tell which one. The outcome is that we cannot reliably create the metadata of those formats and be sure the controller BIOS will understand it. However write support is needed to update/fail/rebuild the arrays properly so it sits fairly high on the TODO list. o So far atapicam is not supported with these changes. When/if this will change is up to the maintainer of atapi-cam so go there for questions. HW donated by: Webveveriet AS HW donated by: Frode Nordahl HW donated by: Yahoo!

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. 2003-03-08T21:32:59Z Poul-Henning Kamp phk@FreeBSD.org 2003-03-08T21:32:59Z urn:sha1:80980460993d69177eb59aee1f6a15a4a65b04a4 2003-02-20T20:02:32Z Søren Schmidt sos@FreeBSD.org 2003-02-20T20:02:32Z urn:sha1:bb5bdd386ebd744a72fb2426f8bd1bc03fb38ebd 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 2002-02-04T19:23:40Z Søren Schmidt sos@FreeBSD.org 2002-02-04T19:23:40Z urn:sha1:6ddce9039bdc992cb1b327de51754c35abdc69a7 Overhaul of the attach/detach code and structures, there were some nasty bugs in the old implementation. This made it possible to collapse the ATA/ATAPI device control structures into one generic structure. A note here, the kernel is NOT ready for detach of active devices, it fails all over in random places, but for inactive devices it works. However for ATA RAID this works, since the RAID abstration layer insulates the buggy^H^H^H^H^H^Hfragile device subsystem from the physical disks. Proberly detect the RAID's from the BIOS, and mark critical RAID1 arrays as such, but continue if there is enough of the mirror left to do so. Properly fail arrays on a live system. For RAID0 that means return EIO, and for RAID1 it means continue on the still working part of the mirror if possible, else return EIO. If the state changes, log this to the console. Allow for Promise & Highpoint controllers/arrays to coexist on the same machine. It is not possible to distribute arrays over different makes of controllers though. If Promise SuperSwap enclosures are used, signal disk state on the status LED on the front. Misc fixes that I had lying around for various minor bugs. Sponsored by: Advanis Inc.
