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! Enjoy! -Søren

Provide the interface to atacontrol and associated logic. see atacontrol(8) for more. Also the ATA_ENABLE_ATAPI_DMA, ATA_ENABLE_WC and ATA_ENABLE_TAGS options are gone, use the tuneables listed in ata.4 instead from the loader (this makes it possible to switch off DMA before the driver has to touch the devices on broken hardware).

Separate the struct bio related stuff out of <sys/buf.h> into <sys/bio.h>. <sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall not be made a nested include according to bdes teachings on the subject of nested includes. Diskdrivers and similar stuff below specfs::strategy() should no longer need to include <sys/buf.> unless they need caching of data. Still a few bogus uses of struct buf to track down.

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! -Søren

#include <vm/pmap.h>
#include <pci/pcivar.h>
* 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.

Add support for the HPT366 chip, this is used on the Abit boards and their HotRod controller and on SIIG PCI ultra DMA controller. These changes also made lots of the Promise code go away, its all much more generic this way. Get rid of atapi_immed_cmd, instead use the queue to move atapi commands from interrupt context if nessesary, the entire atapi layer has gotten an overhaul. Lots of fixes to utililize the new features in subr_disk.c etc, and get rid of the last biots of softc arrays in the drivers, the only one left is atadevices which cannot easily go away (yet). Use our own malloc names, its a lot easier to track memory usage this way. General cleanup overall.

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. Sponsored by: Advanis Inc.

/* misc defines */
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.

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. Sponsored by: Advanis Inc.

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. Add support for the Promise ATA100 OEM chip (pdc20265) Add support for the Cyrix 5530 Change the way status is read from the drives, use the alternate status reg when possible. Better support for DEVFS, the acdXtY devices are now created when needed. Lots of little cleanups.

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! Enjoy! -Søren

Add support for the HPT366 chip, this is used on the Abit boards and their HotRod controller and on SIIG PCI ultra DMA controller. These changes also made lots of the Promise code go away, its all much more generic this way. Get rid of atapi_immed_cmd, instead use the queue to move atapi commands from interrupt context if nessesary, the entire atapi layer has gotten an overhaul. Lots of fixes to utililize the new features in subr_disk.c etc, and get rid of the last biots of softc arrays in the drivers, the only one left is atadevices which cannot easily go away (yet). Use our own malloc names, its a lot easier to track memory usage this way. General cleanup overall.

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.

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! Enjoy! -Søren

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! -Søren

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.

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. Lots of cosmetic fixes here and there. Sorry for the size of this megapatchfromhell but it was not possible otherwise... newbus patches based on work from: dfr (Doug Rabson)

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! -Søren

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! Enjoy! -Søren

Unbreak ATAPI on the Aladdin chipset, only DMA access worked. Try to use a 32bit mask on the IO addresses, this fixes the alpha and hopefully doesn't break on any i386 machines. Try to enable both read & write cache on disks, they should be as default, but better be sure..

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.

Add DMA support for the SiS 5591 and old PIIX chipsets. Add a missing DELAY(1) in ata_wait. Change the info from ad_version, so the ATA version from the disk can be used to quantify the DAM modes valid for this drive, ie be more selective with turning DMA on on older disks that should not support it.. Fix the probe for BIOS enabled DMA in the generic case, master/slave was reversed in the test. 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... Cleanup the printf's in the drivers, use the prober device name (if possible) instead of ataN-master/slave.

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! Enjoy! -Søren

Lots of fixes to utililize the new features in subr_disk.c etc, and get rid of the last biots of softc arrays in the drivers, the only one left is atadevices which cannot easily go away (yet).

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! -Søren

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! -Søren

Unbreak ATAPI on the Aladdin chipset, only DMA access worked. Try to use a 32bit mask on the IO addresses, this fixes the alpha and hopefully doesn't break on any i386 machines. Try to enable both read & write cache on disks, they should be as default, but better be sure..

Get rid of atapi_immed_cmd, instead use the queue to move atapi commands from interrupt context if nessesary, the entire atapi layer has gotten an overhaul. Lots of fixes to utililize the new features in subr_disk.c etc, and get rid of the last biots of softc arrays in the drivers, the only one left is atadevices which cannot easily go away (yet).

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.

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.

Add support for the HPT366 chip, this is used on the Abit boards and their HotRod controller and on SIIG PCI ultra DMA controller. These changes also made lots of the Promise code go away, its all much more generic this way. Get rid of atapi_immed_cmd, instead use the queue to move atapi commands from interrupt context if nessesary, the entire atapi layer has gotten an overhaul. Lots of fixes to utililize the new features in subr_disk.c etc, and get rid of the last biots of softc arrays in the drivers, the only one left is atadevices which cannot easily go away (yet). Use our own malloc names, its a lot easier to track memory usage this way. General cleanup overall.

Fix the probe for BIOS enabled DMA in the generic case, master/slave was reversed in the test. 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... Cleanup the printf's in the drivers, use the prober device name (if possible) instead of ataN-master/slave.

case 0x55131039: /* SiS 5591 */
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. Sponsored by: Advanis Inc.

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.

Add DMA support for the SiS 5591 and old PIIX chipsets. Add a missing DELAY(1) in ata_wait. Change the info from ad_version, so the ATA version from the disk can be used to quantify the DAM modes valid for this drive, ie be more selective with turning DMA on on older disks that should not support it.. Fix the probe for BIOS enabled DMA in the generic case, master/slave was reversed in the test. 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... Cleanup the printf's in the drivers, use the prober device name (if possible) instead of ataN-master/slave.

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.

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.

Fix IRQ allocation bug on controllers using a shared interrupt. Fix a bug which could cause panics in ad/atapi-interrupt. Add support for UDMA66 on Promise Ultra/Fasttrak controllers. Get rid of ATA_IGNORE_INTR, and introduce ATA_WAIT_INTR instead. Add a delay in the dump routine in ata-disk.c, some controllers seem to need this. Also dont use the timeout watchdog when dumping. Disable DMA on ATAPI devices as default, add option ATA_ENABLE_ATAPI_DMA for those that has HW that works. Add support for some not-up-to-spec ATAPI devices that returns data together with completition status on data moving cmd's.

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. Sponsored by: Advanis Inc.

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.

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! -Søren

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! Enjoy! -Søren

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. Sponsored by: Advanis Inc.

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! Enjoy! -Søren

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! -Søren

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! Enjoy! -Søren

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! -Søren

These changes also made lots of the Promise code go away, its all much more generic this way. Get rid of atapi_immed_cmd, instead use the queue to move atapi commands from interrupt context if nessesary, the entire atapi layer has gotten an overhaul. Lots of fixes to utililize the new features in subr_disk.c etc, and get rid of the last biots of softc arrays in the drivers, the only one left is atadevices which cannot easily go away (yet). Use our own malloc names, its a lot easier to track memory usage this way. General cleanup overall.

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! -Søren

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. Sponsored by: Advanis Inc.

ata_prtdev(atadev, "%s setting WDMA2 on generic chip\n",
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.

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! Enjoy! -Søren

Add support for the Promise ATA100 OEM chip (pdc20265) Add support for the Cyrix 5530 Change the way status is read from the drives, use the alternate status reg when possible.

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. Sponsored by: Advanis Inc.

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.

Add support for the HPT366 chip, this is used on the Abit boards and their HotRod controller and on SIIG PCI ultra DMA controller. These changes also made lots of the Promise code go away, its all much more generic this way. Get rid of atapi_immed_cmd, instead use the queue to move atapi commands from interrupt context if nessesary, the entire atapi layer has gotten an overhaul. Lots of fixes to utililize the new features in subr_disk.c etc, and get rid of the last biots of softc arrays in the drivers, the only one left is atadevices which cannot easily go away (yet). Use our own malloc names, its a lot easier to track memory usage this way. General cleanup overall.

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. Sponsored by: Advanis Inc.

Lots of fixes to utililize the new features in subr_disk.c etc, and get rid of the last biots of softc arrays in the drivers, the only one left is atadevices which cannot easily go away (yet).

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.

I can write >64MB/s on the promise and >50MB/s on the HPT370 so it seems writing is still done in ATA66 mode :( The ICH2 support is untested as of yet...

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. Sponsored by: Advanis Inc.

Add support for the HPT366 chip, this is used on the Abit boards and their HotRod controller and on SIIG PCI ultra DMA controller. These changes also made lots of the Promise code go away, its all much more generic this way. Get rid of atapi_immed_cmd, instead use the queue to move atapi commands from interrupt context if nessesary, the entire atapi layer has gotten an overhaul. Lots of fixes to utililize the new features in subr_disk.c etc, and get rid of the last biots of softc arrays in the drivers, the only one left is atadevices which cannot easily go away (yet). Use our own malloc names, its a lot easier to track memory usage this way. General cleanup overall.
