* Remove all legacy ATA code parts, not used since options ATA_CAM enabled inAlexander Motin2013-04-041-607/+0

| | | | | | | | | | | It seems strchr() and strrchr() are used more often than index() and rindex(). Therefore, simply migrate all kernel code to use it. For the XFS code, remove an empty line to make the code identical to the code in the Linux kernel. Notes: svn path=/head/; revision=229272

* 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
* Rework device probing by moving ata_getparam() call from ata_identify() toAlexander Motin2009-02-281-0/+12
| | | | | | | | | | | | | | drivers' probe routines. It allows not to sleep and so not drop Giant inside ata_identify() critical section and so avoid crash if it reentered on request timeout. 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 softc memory deallocation on device destruction. Notes: svn path=/head/; revision=189166

* 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.
