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

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.

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.

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)

/* device structures */
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. 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...

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.

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

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

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).

Finally!! The much roumored replacement for our current IDE/ATA/ATAPI is materialising in the CVS repositories around the globe. So what does this bring us: A new reengineered ATA/ATAPI subsystem, that tries to overcome most of the deficiencies with the current drivers. It supports PCI as well as ISA devices without all the hackery in ide_pci.c to make PCI devices look like ISA counterparts. It doesn't have the excessive wait problem on probe, in fact you shouldn't notice any delay when your devices are getting probed. Probing and attaching of devices are postponed until interrupts are enabled (well almost, not finished yet for disks), making things alot cleaner. Improved performance, although DMA support is still WIP and not in this pre alpha release, worldstone is faster with the new driver compared to the old even with DMA. So what does it take away: There is NO support for old MFM/RLL/ESDI disks. There is NO support for bad144, if your disk is bad, ditch it, it has already outgrown its internal spare sectors, and is dying. For you to try this out, you will have to modify your kernel config file to use the "ata" controller instead of all wdc? entries. example: # for a PCI only system (most modern machines) controller ata0 device atadisk0 # ATA disks device atapicd0 # ATAPI CDROM's device atapist0 # ATAPI tapes #You should add the following on ISA systems: controller ata1 at isa? port "IO_WD1" bio irq 14 controller ata2 at isa? port "IO_WD2" bio irq 15 You can leave it all in there, the system knows how to manage.

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.

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...

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

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

It doesn't have the excessive wait problem on probe, in fact you shouldn't notice any delay when your devices are getting probed. Probing and attaching of devices are postponed until interrupts are enabled (well almost, not finished yet for disks), making things alot cleaner. Improved performance, although DMA support is still WIP and not in this pre alpha release, worldstone is faster with the new driver compared to the old even with DMA. So what does it take away: There is NO support for old MFM/RLL/ESDI disks. There is NO support for bad144, if your disk is bad, ditch it, it has already outgrown its internal spare sectors, and is dying. For you to try this out, you will have to modify your kernel config file to use the "ata" controller instead of all wdc? entries. example: # for a PCI only system (most modern machines) controller ata0 device atadisk0 # ATA disks device atapicd0 # ATAPI CDROM's device atapist0 # ATAPI tapes #You should add the following on ISA systems: controller ata1 at isa? port "IO_WD1" bio irq 14 controller ata2 at isa? port "IO_WD2" bio irq 15 You can leave it all in there, the system knows how to manage. For now this driver reuses the device entries from the old system (that will probably change later), but remember that disks are now numbered in the sequence they are found (like the SCSI system) not as absolute positions as the old system. Although I have tested this on all the systems I can get my hands on, there might very well be gremlins in there, so use AT YOU OWN RISK!! This is still WIP, so there are lots of rough edges and unfinished things in there, and what I have in my lab might look very different from whats in CVS at any given time. So please have all eventual changes go through me, or chances are they just dissapears... I would very much like to hear from you, both good and bad news are very welcome. Enjoy!! -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.

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

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.

For you to try this out, you will have to modify your kernel config file to use the "ata" controller instead of all wdc? entries. example: # for a PCI only system (most modern machines) controller ata0 device atadisk0 # ATA disks device atapicd0 # ATAPI CDROM's device atapist0 # ATAPI tapes #You should add the following on ISA systems: controller ata1 at isa? port "IO_WD1" bio irq 14 controller ata2 at isa? port "IO_WD2" bio irq 15 You can leave it all in there, the system knows how to manage. For now this driver reuses the device entries from the old system (that will probably change later), but remember that disks are now numbered in the sequence they are found (like the SCSI system) not as absolute positions as the old system. Although I have tested this on all the systems I can get my hands on, there might very well be gremlins in there, so use AT YOU OWN RISK!! This is still WIP, so there are lots of rough edges and unfinished things in there, and what I have in my lab might look very different from whats in CVS at any given time. So please have all eventual changes go through me, or chances are they just dissapears... I would very much like to hear from you, both good and bad news are very welcome. Enjoy!! -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

/* flush buffers, some drives fail here, they should report ctl = 0 */
Finally!! The much roumored replacement for our current IDE/ATA/ATAPI is materialising in the CVS repositories around the globe. So what does this bring us: A new reengineered ATA/ATAPI subsystem, that tries to overcome most of the deficiencies with the current drivers. It supports PCI as well as ISA devices without all the hackery in ide_pci.c to make PCI devices look like ISA counterparts. It doesn't have the excessive wait problem on probe, in fact you shouldn't notice any delay when your devices are getting probed. Probing and attaching of devices are postponed until interrupts are enabled (well almost, not finished yet for disks), making things alot cleaner. Improved performance, although DMA support is still WIP and not in this pre alpha release, worldstone is faster with the new driver compared to the old even with DMA. So what does it take away: There is NO support for old MFM/RLL/ESDI disks.

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...

Although I have tested this on all the systems I can get my hands on, there might very well be gremlins in there, so use AT YOU OWN RISK!! This is still WIP, so there are lots of rough edges and unfinished things in there, and what I have in my lab might look very different from whats in CVS at any given time. So please have all eventual changes go through me, or chances are they just dissapears... I would very much like to hear from you, both good and bad news are very welcome. Enjoy!! -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.

Finally!! The much roumored replacement for our current IDE/ATA/ATAPI is materialising in the CVS repositories around the globe. So what does this bring us: A new reengineered ATA/ATAPI subsystem, that tries to overcome most of the deficiencies with the current drivers. It supports PCI as well as ISA devices without all the hackery in ide_pci.c to make PCI devices look like ISA counterparts. It doesn't have the excessive wait problem on probe, in fact you shouldn't notice any delay when your devices are getting probed. Probing and attaching of devices are postponed until interrupts are enabled (well almost, not finished yet for disks), making things alot cleaner. Improved performance, although DMA support is still WIP and not in this pre alpha release, worldstone is faster with the new driver compared to the old even with DMA. So what does it take away: There is NO support for old MFM/RLL/ESDI disks. There is NO support for bad144, if your disk is bad, ditch it, it has already outgrown its internal spare sectors, and is dying. For you to try this out, you will have to modify your kernel config file to use the "ata" controller instead of all wdc? entries. example: # for a PCI only system (most modern machines) controller ata0 device atadisk0 # ATA disks device atapicd0 # ATAPI CDROM's device atapist0 # ATAPI tapes #You should add the following on ISA systems: controller ata1 at isa? port "IO_WD1" bio irq 14 controller ata2 at isa? port "IO_WD2" bio irq 15 You can leave it all in there, the system knows how to manage.

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.

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.

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

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.

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

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

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

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.

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

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.

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

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).

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

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

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.

Fixed problems: Dont use more sectors/intr than the drive supports. Fix announce of > 8.4G disks. Dont call ad_interrupt/ad_transfer when no disks config'd. Use the right page# for CDR write mode params. Fix breakage when no PCI support in kernel. Implement DEVFS stuff. General code clenaup.

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

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

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 is still WIP, so there are lots of rough edges and unfinished things in there, and what I have in my lab might look very different from whats in CVS at any given time. So please have all eventual changes go through me, or chances are they just dissapears... I would very much like to hear from you, both good and bad news are very welcome. Enjoy!! -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.

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

Finally!! The much roumored replacement for our current IDE/ATA/ATAPI is materialising in the CVS repositories around the globe. So what does this bring us: A new reengineered ATA/ATAPI subsystem, that tries to overcome most of the deficiencies with the current drivers. It supports PCI as well as ISA devices without all the hackery in ide_pci.c to make PCI devices look like ISA counterparts. It doesn't have the excessive wait problem on probe, in fact you shouldn't notice any delay when your devices are getting probed. Probing and attaching of devices are postponed until interrupts are enabled (well almost, not finished yet for disks), making things alot cleaner. Improved performance, although DMA support is still WIP and not in this pre alpha release, worldstone is faster with the new driver compared to the old even with DMA. So what does it take away: There is NO support for old MFM/RLL/ESDI disks. There is NO support for bad144, if your disk is bad, ditch it, it has already outgrown its internal spare sectors, and is dying. For you to try this out, you will have to modify your kernel config file to use the "ata" controller instead of all wdc? entries. example: # for a PCI only system (most modern machines) controller ata0 device atadisk0 # ATA disks device atapicd0 # ATAPI CDROM's device atapist0 # ATAPI tapes #You should add the following on ISA systems: controller ata1 at isa? port "IO_WD1" bio irq 14 controller ata2 at isa? port "IO_WD2" bio irq 15 You can leave it all in there, the system knows how to manage.

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

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

if (error)
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).
