* MFp4:Alexander Motin2009-12-061-3/+4
| | | | | | | | | | | | | | | | | | | | | Introduce ATA_CAM kernel option, turning ata(4) controller drivers into cam(4) interface modules. When enabled, this options deprecates all ata(4) peripheral drivers (ad, acd, ...) and interfaces and allows cam(4) drivers (ada, cd, ...) and interfaces to be natively used instead. As side effect of this, ata(4) mode setting code was completely rewritten to make controller API more strict and permit above change. While doing this, SATA revision was separated from PATA mode. It allows DMA-incapable SATA devices to operate and makes hw.ata.atapi_dma tunable work again. Also allow ata(4) controller drivers (except some specific or broken ones) to handle larger data transfers. Previous constraint of 64K was artificial and is not really required by PCI ATA BM specification or hardware. Submitted by: nwitehorn (powerpc part) Notes: svn path=/head/; revision=200171

* Improve kernel dumping reliability for busy ATA channels:Alexander Motin2009-05-011-2/+10
| | | | | | | | | | | | - Generate fake channel interrupts even if channel busy with previous request to let it finish. Without this, dumping requests were just queued and never processed. - Drop pre-dump requests queue on dumping. ATA code, working in dumping (interruptless) mode, unable to handle long request queue. Actually, to get coherent dump we anyway should do as few unrelated actions as possible. Notes: svn path=/head/; revision=191717
* Revert my ata_identify()/ata_reinit() related changes: r189166, r189091Alexander Motin2009-02-281-12/+0
| | | | | | | | | | | | | | | | | and partially r188903. Revert breaks new drives detection on reinit to the state as it was before me, but fixes series of new bugs reported by some people. Unconditional queueing of ata_completed() calls can lead to deadlock if due to timeout ata_reinit() was called at the same thread by previous ata_completed(). Calling of ata_identify() on ata_reinit() in current implementation opens numerous races and deadlocks. Problems I was touching here are still exist and should be addresed, but probably in different way. Notes: svn path=/head/; revision=189195

Reentering of probe call checked inside of it. Give device own knowledge about it's type (ata/atapi/atapicam). It is not a good idea to ask channel status for device type inside ata_getparam().

* Add a "spindown" facility to ata-disks: If no requests have been receivedPoul-Henning Kamp2008-03-171-1/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | for a configurable number of seconds, spin the disk down. Spin it back up on the next request. Notice that the timeout is only armed by a request, so to spin down a disk you may have to do: atacontrol spindown ad10 5 dd if=/dev/ad10 of=/dev/null count=1 To disable spindown, set timeout to zero: atacontrol spindown ad10 0 In order to debug any trouble caused, this code is somewhat noisy on the console. Enabling spindown on a disk containing / or /var/log/messages is not going to do anything sensible. Spinning a disk up and down all the time will wear it out, use sensibly.

* Most platforms map the actual drive geometry to the firmware's notionWarner Losh2006-08-091-0/+9
| | | | | | | | | | | | | | | | | | | | | | | of geometry. However, some platforms have a more complicated mapping of the firmware values to the actual values. pc98 is the only platform that currently does this. This mapping is necessary for large disks connected to pc98 boxes, as the firmware labels require do special hacks to the actual geometry for interoperability. We cannot do this all in the geom layer because of initialization issues (geom looks for an already initialized pc98 label, but we need the geometry information prior to initialization, classic chicken and egg problem). We pass the disk and the device_t to this function because the geometry mapping depends on what kind of controller is used. This hook allows platforms that want to override things to do so, and has 0 overhead on all other platforms. These patches have been in use locally for a long time, and received good feedback from the pc98 community and sos@ at various times during their development.

* Normalize a significant number of kernel malloc type names:Robert Watson2005-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | - Prefer '_' to ' ', as it results in more easily parsed results in memory monitoring tools such as vmstat. - Remove punctuation that is incompatible with using memory type names as file names, such as '/' characters. - Disambiguate some collisions by adding subsystem prefixes to some memory types. - Generally prefer lower case to upper case. - If the same type is defined in multiple architecture directories, attempt to use the same name in additional cases. Not all instances were caught in this change, so more work is required to finish this conversion. Similar changes are required for UMA zone names. Notes: svn path=/head/; revision=151897

* This is the much rumoured ATA mkIII update that I've been working on.Søren Schmidt2005-03-301-225/+238
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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!
