MFp4: 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.

Revert my ata_identify()/ata_reinit() related changes: r189166, r189091 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.

Rework device probing by moving ata_getparam() call from ata_identify() to 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().

Replace all calls to minor() with dev2unit().
After I removed all the unit2minor()/minor2unit() calls from the kernel yesterday, I realised calling minor() everywhere is quite confusing. Character devices now only have the ability to store a unit number, not a minor number. Remove the confusion by using dev2unit() everywhere.
This commit could also be considered as a bug fix. A lot of drivers call minor(), while they should actually be calling dev2unit(). In -CURRENT this isn't a problem, but it turns out we never had any problem reports related to that issue in the past. I suspect not many people connect more than 256 pieces of the same hardware.

Normalize a significant number of kernel malloc type names:
- 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.

This is the much rumoured ATA mkIII update that I've been working on.
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.

Overhaul of the timeout/reinit framework. This should clear up most of the leftovers from the old version that really doesn't work anymore.
Add a reset function for host-end of the ATA channel. This is needed for the SiI3112 in order to whack it back to reality if a device locks up the SATA interface (thereby preventing that we can reset the device). The result is that ATA now recovers from the timeouts that happens with the SiI3112A and more or less all disks based on old PATA electronics with a Marvell PATA->SATA converter. This includes lots of the popular SATA dongles and the WDC Raptor disks..

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

Major update of the ATA RAID code, part 1:
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.

Remove B_READ, B_WRITE and B_FREEBUF and replace them with a new field in struct buf: b_iocmd. The b_iocmd is enforced to have exactly one bit set.
B_WRITE was bogusly defined as zero giving rise to obvious coding mistakes.
Also eliminate the redundant struct buf flag B_CALL, it can just as efficiently be done by comparing b_iodone to NULL.
Should you get a panic or drop into the debugger, complaining about "b_iocmd", don't continue. It is likely to write on your disk where it should have been reading.
This change is a step in the direction towards a stackable BIO capability.
A lot of this patch were machine generated (Thanks to style(9) compliance!)
Vinum users: Greg has not had time to test this yet, be careful.

Update the ata driver to take more advantage of newbus, this was needed to make attach/detach of devices work, which is needed for the PCCARD support. (PCCARD support is still not working though, more to come on that)
Support the CMD646 chip which is used on many alphas, sadly only in WDMA2 mode, as the silicon is broken beyond belief for UDMA modes.

General cleanup.
Dont be so verbose in the probe, only ONE line printed now, to get more info boot verbose. Centralise most printf's in ata-all & ata-dma to use the ata_printf function, it saves alot of codelines.
Repeat the identify command if drive fails the first.
Protect the timeout functions with splbio.
Dont update the transfer details before we are sure the transfer succeded, this way they are proberly retried on errors.
Move the handling of next_writeable to userland.
Use the READ_CD command to read CD's. That enables us to read _anything_ via the normal read/write interface. This kindof obsoletes the READAUDIO ioctl, but we keep that for now.

Check the return for ata_command in all cases, and print warnings if it fails.
Call ata_dmainit with all dmamodes off when falling back to PIO mode, that should take care of both the Promise & HPT366 controllers not being able to handle the fallback...

Ten'th update to the new ATA/ATAPI driver:
It been awhile since the last major update, as a benefit there are some cool things in this one (and new bugs probably :) )...
The ATA driver has grown "real" timeout support for all devices. This means that it should be possible to get in contact with (especially) lost ATAPI devices. It also means that the ATA driver is now usable on notebooks as it will DTRT on resume.
An experimental hack at utilizing the Promise66's at UDMA66 is in there, but I cant test it. If someone feels like sending me one, give me a ping.
The ATAPI DMA enableling scheme has been changed, also better DMA support for the Aladdin chipset has been implemented for ATAPI devices. Note that the Aladdin apparently only can do DMA reads on ATAPI devices, and the Promise cant do ATAPI DMA at all. I have seen problems on some ATAPI devices that should be able to run in DMA mode, so if you encounter problems with hanging atapi devices during the probe, or during access, disable DMA in atapi-all.c, and let me know. It might be nessesary to do this via a "white list" for known good devices...
The ATAPI CDROM driver can now use eject/close without hanging and the bug that caused reading beyond the end of a CD has been fixed. Media change is also handled proberly. DVD drives are identified and are usable as CDROM devices at least, I dont have the HW to test this further, see above :).
The ATAPI tape driver has gotten some support for using the DSC method for not blocking the IDE channel during read/write when the device has full buffers. It knows about the OnStream DI-30 device, support is not completed yet, but it can function as a primitive backup medium, without filemarks, and without bad media handeling. This is because the OnStream device doesn't handle this (like everybody else) in HW. It also now supports getting/setting the record position on devices that supports it.
Some rather major cleanups and rearrangements as well (cvs -b diff is your freind). I'm closing in on declaring this for beta code, most of the infrastruture is in place by now.
As usual USE AT YOUR OWN RISK!!, this is still alpha level code. This driver can hose your disk real bad if anything goes wrong, but now you have been warned :)
But please tell me how it works for you!
Enjoy!

Convert DEVFS hooks in (most) drivers to make_dev().
Diskslice/label code not yet handled.
Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)
Add the correct hook for devfs to kern_conf.c
The net result of this excercise is that a lot less files depends on DEVFS, and devtoname() gets more sensible output in many cases.
A few drivers had minor additional cleanups performed relating to cdevsw registration.
A few drivers don't register a cdevsw{} anymore, but only use make_dev().

Nine'th update to the new ATA/ATAPI driver:
The atapi subsystem has gotten better error handeling and timeouts, it also tries a REQUEST SENSE command when devices returns errors, to give a little more info as to what went wrong. It might be a little verbose for now, but I'm interested in as much feedback on errors as possible, especially timeouts, as I'm a bit in doubt if I've chosen resonable default values everywhere.
The disk driver has been changed a bit to prepare for tagged queing, which is next on my list.
The disk driver has grown a dump routine, I got one implementation from Darrell Anderson <anderson@cs.duke.edu> which also did partial dumps (usefull on big memory machines) I left out the partial stuff for now, and changed the rest alot to fit into the new ad_request framework.
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...
But please tell me how it works for you!
Enjoy!

Simplify cdevsw registration.
The cdevsw_add() function now finds the major number(s) in the struct cdevsw passed to it. cdevsw_add_generic() is no longer needed, cdevsw_add() does the same thing.
cdevsw_add() will print an message if the d_maj field looks bogus.
Remove nblkdev and nchrdev variables. Most places they were used bogusly. Instead check a dev_t for validity by seeing if devsw() or bdevsw() returns NULL.
Move bdevsw() and devsw() functions to kern/kern_conf.c
Bump __FreeBSD_version to 400006
This commit removes: 72 bogus makedev() calls 26 bogus SYSINIT functions
if_xe.c bogusly accessed cdevsw[], author/maintainer please fix.

This commit should be a extensive NO-OP:
Reformat and initialize correctly all "struct cdevsw".
Initialize the d_maj and d_bmaj fields.
The d_reset field was not removed, although it is never used.
I used a program to do most of this, so all the files now use the same consistent format. Please keep it that way.

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!

Now all actual probing of both ATA & ATAPI devices are done after interrupts are enabled, this kills the last "unwanted interrupts" (and there is no ugly hacks like in the old driver to avoid them). COmmand interrupt devices are now supported, this applies mostly to older CDROM's and apparently also the ZIP.
Fixed problems:
Number of total sectors wrong on some older drives. Fixed by not using the LBA size unless we know its valid.
There has also been more general code clenaups, some reorgs also.

Finally!!
The much roumored replacement for our current IDE/ATA/ATAPI is materialising in the CVS repositories around the globe.
So what does this bring us:
A new reengineered ATA/ATAPI subsystem, that tries to overcome most of the deficiencies with the current drivers.
It supports PCI as well as ISA devices without all the hackery in ide_pci.c to make PCI devices look like ISA counterparts.
It doesn't have the excessive wait problem on probe, in fact you shouldn't notice any delay when your devices are getting probed.
Probing and attaching of devices are postponed until interrupts are enabled (well almost, not finished yet for disks), making things alot cleaner.
Improved performance, although DMA support is still WIP and not in this pre alpha release, worldstone is faster with the new driver compared to the old even with DMA.
So what does it take away:
There is NO support for old MFM/RLL/ESDI disks. There is NO support for bad144, if your disk is bad, ditch it, it has already outgrown its internal spare sectors, and is dying.
For you to try this out, you will have to modify your kernel config file to use the "ata" controller instead of all wdc? entries.
example:
# for a PCI only system (most modern machines) controller ata0 device atadisk0 # ATA disks device atapicd0 # ATAPI CDROM's device atapist0 # ATAPI tapes
#You should add the following on ISA systems: controller ata1 at isa? port "IO_WD1" bio irq 14 controller ata2 at isa? port "IO_WD2" bio irq 15
You can leave it all in there, the system knows how to manage.
For now this driver reuses the device entries from the old system (that will probably change later), but remember that disks are now numbered in the sequence they are found (like the SCSI system) not as absolute positions as the old system.
Although I have tested this on all the systems I can get my hands on, there might very well be gremlins in there, so use AT YOU OWN RISK!! This is still WIP, so there are lots of rough edges and unfinished things in there, and what I have in my lab might look very different from whats in CVS at any given time. So please have all eventual changes go through me, or chances are they just dissapears...
I would very much like to hear from you, both good and bad news are very welcome.
Enjoy!!
