Remove remnants of ATA_LOCKING uses in the ATA_CAM case and wrap it along with functions, SYSCTLs and tunables that are not used with ATA_CAM in #ifndef ATA_CAM, similar to the existing #ifdef'ed ATA_CAM code for the other way around. This makes it easier to understand which parts of ata(4) actually are used in the new world order and to later on remove the !ATA_CAM bits. It also makes it obvious that there is something fishy with the C-bus front-end as well as in the ATP850 support, as these used ATA_LOCKING which is defunct in the ATA_CAM case. When fixing the former, ATA_LOCKING probably needs to be brought back in some form or other.

Add a "kern.features.ata_cam" sysctl in the kernel when the ATA_CAM kernel option is defined. This sysctl can be queried by feature_present(3).
Query for this feature in /sbin/atacontrol and /usr/sbin/burncd. If these utilities detect that ATA_CAM is enabled, then these utilities will error out. These utilities are compatible with the old ATA driver, but are incomptible with the new ATA_CAM driver. By erroring out, we give end-users an idea as to what remedies to use, and reduce the need for them to file PR's. For atacontrol, camcontrol must be used instead, and for burncd, alternative utilties from the ports collection must be used such as sysutils/cdrtools.
In future, maybe someone can re-write burncd to work with ATA_CAM, but at least for now, we give a somewhat useful error message to end users.

MFp4: Large set of CAM inprovements.
- Unify bus reset/probe sequence. Whenever bus attached at boot or later, CAM will automatically reset and scan it. It allows to remove duplicate code from many drivers. - Any bus, attached before CAM completed it's boot-time initialization, will equally join to the process, delaying boot if needed. - New kern.cam.boot_delay loader tunable should help controllers that are still unable to register their buses in time (such as slow USB/ PCCard/ CardBus devices), by adding one more event to wait on boot. - To allow synchronization between different CAM levels, concept of requests priorities was extended. Priorities now split between several "run levels". Device can be freezed at specified level, allowing higher priority requests to pass. For example, no payload requests allowed, until PMP driver enable port. ATA XPT negotiate transfer parameters, periph driver configure caching and so on. - Frozen requests are no more counted by request allocation scheduler. It fixes deadlocks, when frozen low priority payload requests occupying slots, required by higher levels to manage theit execution. - Two last changes were holding proper ATA reinitialization and error recovery implementation. Now it is done: SATA controllers and Port Multipliers now implement automatic hot-plug and should correctly recover from timeouts and bus resets. - Improve SCSI error recovery for devices on buses without automatic sense reporting, such as ATAPI or USB. For example, it allows CAM to wait, while CD drive loads disk, instead of immediately return error status. - Decapitalize diagnostic messages and make them more readable and sensible. - Teach PMP driver to limit maximum speed on fan-out ports. - Make boot wait for PMP scan completes, and make rescan more reliable. - Fix pass driver, to return CCB to user level in case of error. - Increase number of retries in cd driver, as device may return several UAs.

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.

Make the newbus subsystem Giant free by adding the new newbus sxlock. The newbus lock is responsible for protecting newbus internIal structures, device states and devclass flags. It is necessary to hold it when all such datas are accessed. For the other operations, softc locking should ensure enough protection to avoid races.
Newbus lock is automatically held when virtual operations on the device and bus are invoked when loading the driver or when the suspend/resume take place. For other 'spourious' operations trying to access/modify the newbus topology, newbus lock needs to be automatically acquired and dropped.
For the moment Giant is also acquired in some key point (modules subsystem) in order to avoid problems before the 8.0 release as module handlers could make assumptions about it. This Giant locking should go just after the release happens.
Please keep in mind that the public interface can be expanded in order to provide more support, if there are really necessities at some point and also some bugs could arise as long as the patch needs a bit of further testing.
Bump __FreeBSD_version in order to reflect the newbus lock introduction.

This is the roumored ATA modulerisation works, and it needs a little explanation.
If you just config KERNEL as usual there should be no apparent changes, you'll get all chipset support code compiled in.
However there is now a way to only compile in code for chipsets needed on a pr vendor basis. ATA now has the following "device" entries:
atacore: ATA core functionality, always needed for any ATA setup
atacard: CARDBUS support atacbus: PC98 cbus support ataisa: ISA bus support atapci: PCI bus support only generic chipset support.
ataahci: AHCI support, also pulled in by some vendor modules.
ataacard, ataacerlabs, ataadaptec, ataamd, ataati, atacenatek, atacypress, atacyrix, atahighpoint, ataintel, ataite, atajmicron, atamarvell, atamicron, atanational, atanetcell, atanvidia, atapromise, ataserverworks, atasiliconimage, atasis, atavia; Vendor support, ie atavia for VIA chipsets
atadisk: ATA disk driver ataraid: ATA softraid driver
atapicd: ATAPI cd/dvd driver atapifd: ATAPI floppy/flashdisk driver atapist: ATAPI tape driver
atausb: ATA<>USB bridge atapicam: ATA<>CAM bridge
This makes it possible to config a kernel with just VIA chipset support by having the following ATA lines in the kernel config file:
device atacore device atapci device atavia
And then you need the atadisk, atapicd etc lines in there just as usual.
If you use ATA as modules loaded at boot there is few changes except the rename of the "ata" module to "atacore", things looks just as usual. However under atapci you now have a whole bunch of vendor specific drivers, that you can kldload individually depending on you needs. Drivers have the same names as used in the kernel config explained above.

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.

Use 'pause' in several places rather than trying to tsleep() on NULL (which triggers a KASSERT) or local variables. In the case of kern_ndis, the tsleep() actually used a common sleep address (curproc) making it susceptible to a premature wakeup.

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.

Add support for the Promise command sequencer present on all modern Promise controllers (PDC203** PDC206**).
This also adds preliminary support for the Promise SX4/SX4000 but *only* as a "normal" Promise ATA controller (ATA RAID's are supported though but only RAID0, RAID1 and RAID0+1).
This cuts off yet another 5-8% of the command overhead on promise controllers, making them the fastest we have ever had support for.
Work is now continuing to add support for this in ATA RAID, to accellerate ATA RAID quite a bit on these controllers, and especially the SX4/SX4000 series as they have quite a few tricks in there..
This commit also adds a few fixes to the SATA code needed for proper support.

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.

Clean up the DMA interface too much unneeded stuff crept in with the busdma code back when.
Modify the ATA_IN* / ATA_OUT* macros so that resource and offset are gotten from a table. That allows for new chipsets that doesn't nessesarily have things ordered the good old way. This also removes the need for the wierd PC98 resource functions.

- Add a new ioctl to get the maximum number of ATA channels. - Use it in atacontrol(8) when listing ATA devices instead of stopping at the first ENXIO received.
This makes atacontrol list work on my sparc64 where the two ATA channels I have are numbered 2 and 3.

First round off updates/fixes to the ATA driver.
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!

Fix crash dumps on ata and scsi.
To fix scsi, don't wait for ithreads if we're dumping, it makes the debugger sad.
To fix ata, use what appears to be a polling method if we're dumping, I stole this from tmm but added code to ensure that this change is only in effect while dumping.

Add support for the PC98 platform to the ATA driver. This mostly consists of functionality to serialize accesses to the two ATA channels (which can also be used to "fix" certain PCI based controllers). Add support for Acard controllers. Enable the ATA driver in PC98 GENERIC, and add device hints. Update man page with latest support.
The PC98 core team has kindly provided me with a PC98 machine that made this all possible, thanks to all that contributed to that effort, without that this would probably newer have been possible..

In ata_reinit, when ata_getparam fails for a new device (indicating that the device is not actually present), clear the corresponding bit in the ch->devices bitmap. This resolves a panic that occurred with ATAPI/CAM after an APM suspend/resume, when the ATA hardware would erroneously report an extra ATAPI device.

Fill in missing parts of the ATAPI/CAM XPT: implement XPT_RESET_BUS and XPT_RESET_DEV.
In order to properly handle reset requests whether they originate in the ATA layer (atacontrol reinit) or from the CAM layer (camcontrol reset) ata_reinit does not cause the SIM to be deallocated anymore. The SIM is now unconditionnally created for each ATAPI bus.
This change may cause existing bus ids to change on some setups.

Add support for creating/deleting ATA RAID's. This completes the ATA RAID support, since all functions to manipulate the RAID are accessible from FreeBSD, the BIOS on the ATA RAID cards are only nessesary for booting.
I decided to allow for creation of ATA RAID's on any ATA controller, but please keep in mind the restrictions on that. Due to the BIOS not knowing what to do you can only boot from a RAID1 or the first disk in a SPAN, if its not located on a "real" ATA RAID controller like the Promise or Highpoint controllers.

Major update of the ATA RAID code, part 3:
Add code to properly detach/attach disks that are part of a RAID.
Mark a disk that is attached on an ATA channel belonging to a RAID as a spare disk that can be used for rebuilding failed RAID1's.
Add support for rebuilding failed RAID1's.
Several fixes to the detach/attach code.
For replacing a disk in a failed RAID1 do the following:
Find the controller channel# of the failed disk.
Exec 'atacontrol detach <channel#>' to free the disk from the system.
Replace the failed disk with a new one of at least the same size. If your have your disks in drawers/enclosures this can be done with the system still running.
Exec 'atacontrol attach <channel#>' to add the disk to the system and mark it as a valid spare for rebuild.
Exec 'atacontrol rebuild <array#>'
The system will rebuild the array on the fly, the array can still be used during this, although with slower performance.
Please let me know of any problems with this!

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.

- Heavyweight interrupt threads on the alpha for device I/O interrupts. - Make softinterrupts (SWI's) almost completely MI, and divorce them completely from the x86 hardware interrupt code. - The ihandlers array is now gone. Instead, there is a MI shandlers array that just contains SWI handlers. - Most of the former machine/ipl.h files have moved to a new sys/ipl.h. - Stub out all the spl*() functions on all architectures.

Add support for tagged queuing on ATA drives. There is only support for IBM's DPTA and DTLA series of drives (no other disk vendors are known to support this) on non-Promise controllers (promise controllers lockup when given the tagged queuing specific commands). It gives especially master/slave comboes about 5% better performance.

Major update to the way synchronization is done in the kernel. Highlights include:
* Mutual exclusion is used instead of spl*(). See mutex(9). (Note: The alpha port is still in transition and currently uses both.)
* Per-CPU idle processes.
* Interrupts are run in their own separate kernel threads and can be preempted (i386 only).

* Completely rewrite the alpha busspace to hide the implementation from the drivers. * Remove legacy inx/outx support from chipset and replace with macros which call busspace. * Rework pci config accesses to route through the pcib device instead of calling a MD function directly.
With these changes it is possible to cleanly support machines which have more than one independantly numbered PCI busses. As a bonus, the new busspace implementation should be measurably faster than the old one.

Diskdrivers and similar stuff below specfs::strategy() should no longer need to include <sys/buf.> unless they need caching of data.

Be much more selective in claiming devices that might be IDE controllers.
The old algorithm was:
if class == storage and subclass != SCSI device must be IDE

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!

This represents essentially a complete rewrite of the ISA PnP code. The new system is integrated with the ISA bus code more cleanly and allows the future addition of more enumerators such as PnPBIOS and ACPI.

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...

Stage 1 of a cleanup of the i386 interrupt registration mechanism. Interrupts under the new scheme are managed by the i386 nexus with the awareness of the resource manager.

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.

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!

ZIP drives should now be working, I'm not sure about LS120 drives, reports on those most welcome!
Fixed problems:
Hang on probe on "fantom" devices. The probe now use a timeout to avoid hangs if no interrupt is recevied.
There has also been more general code clenaups, and some reorgs.

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.

Added driver to support ATAPI floppies ie LS-120 & ZIP drives.
Added "options ATA_STATIC_ID" that wires ATA disks like the old wd driver.
Fixed problems:
Dont use more sectors/intr than the drive supports. Fix announce of > 8.4G disks. Dont call ad_interrupt/ad_transfer when no disks config'd. Use the right page# for CDR write mode params. Fix breakage when no PCI support in kernel. Implement DEVFS stuff.
General code clenaup.

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!!
