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.

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.

Have another go at the VIA support, this time use the PCI ID form the main component in the southbridge chip to determine which VIA chip we are dealing with. Try to enable DMA on generic controllers that say they has the capability, instead of relying on the BIOS to have set it up.

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

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)

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...

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.

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.

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

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.

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.

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

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.

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).

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

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.

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.

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

Refine the detach/attach code. Proberly fail outstanding bio requests on devices that are detached. This makes it possible to change between disk/cdrom/dvd/whathaveyou in a notebook, just by suspending it, changing the device in the bay (or what you model calls it), unsuspend and the ATA driver will figure out what disappeared and properly fail those, and attach any new devices found.

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.

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.

This makes it possible to change between disk/cdrom/dvd/whathaveyou in a notebook, just by suspending it, changing the device in the bay (or what you model calls it), unsuspend and the ATA driver will figure out what disappeared and properly fail those, and attach any new devices found.

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

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.

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

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.

Nine'th update to the new ATA/ATAPI driver: The atapi subsystem has gotten better error handeling and timeouts, it also tries a REQUEST SENSE command when devices returns errors, to give a little more info as to what went wrong. It might be a little verbose for now, but I'm interested in as much feedback on errors as possible, especially timeouts, as I'm a bit in doubt if I've chosen resonable default values everywhere. The disk driver has been changed a bit to prepare for tagged queing, which is next on my list. The disk driver has grown a dump routine, I got one implementation from Darrell Anderson <anderson@cs.duke.edu> which also did partial dumps (usefull on big memory machines) I left out the partial stuff for now, and changed the rest alot to fit into the new ad_request framework. Some minor cleanups and rearrangements as well. As usual USE AT YOUR OWN RISK!!, this is still pre alpha level code. Especially the DMA support can hose your disk real bad if anything goes wrong, again you have been warned :) Notebook owners should be carefull that their machines dont suspend as this might cause trouble... But please tell me how it works for you! Enjoy! -Søren

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.

Refine the detach/attach code. Proberly fail outstanding bio requests on devices that are detached. This makes it possible to change between disk/cdrom/dvd/whathaveyou in a notebook, just by suspending it, changing the device in the bay (or what you model calls it), unsuspend and the ATA driver will figure out what disappeared and properly fail those, and attach any new devices found.
