| 2008-09-25 | Initialize 'capacity' to 0 and use tabs to indent. "won't hurt" miod@. | Kenneth R Westerback | |
| 2008-05-05 | Don't set the adaptor template link's flags and quirks when trying to | Kenneth R Westerback | |
| set the flags and quirks for a device. Should fix weird issues where the device after an ATAPI device gets marked as ATAPI. First reported on misc@ by Daniel Wade, who also provided some useful testing. ok dlg@ | |||
| 2008-03-26 | plug a mem leak. the array of ports wasnt freed on detach. | David Gwynne | |
| 2007-12-30 | dont freeze lock or set caching modes on ata devices that arent disks, its | David Gwynne | |
| not a good idea. found by simon@ who plugged a sata dvd drive into ahci. | |||
| 2007-12-29 | the scsi layer always had function pointers for asking the hba about a | David Gwynne | |
| device before issuing scsi commands to it, but it was never implemented, never used, and no hba actually filled them in. i came along and added another two function pointers for the same thing. this cleans up the extra pointers. ok krw@ marco@ miod@ deraadt@ | |||
| 2007-12-28 | provide vpd page 0, which lists which vpd pages we provide. | David Gwynne | |
| 2007-12-28 | rename some functions to make it clear theyre used to emulate vpd responses | David Gwynne | |
| 2007-12-28 | implement emulation of vpd page 83, the device identification page. if the | David Gwynne | |
| disk provides a wwn, use it, otherwise do our best to generate an id from the model and serial number. | |||
| 2007-12-28 | massage the way vpds are defined. rename the page used for the devices | David Gwynne | |
| serial number and split the vpd header out for use in other places. while here define the device identification page bits too. ok krw@ marco@ | |||
| 2007-12-09 | unify synchronous scsi xfer completion handling. this started out as a fix | David Gwynne | |
| to the completions for some scsi commands we simply ack in the disk_cmd handler. | |||
| 2007-12-09 | remove the nosleep argument to ata_get_xfer. it is a relic from when i | David Gwynne | |
| used to allocated xfers out of a pool rather than as part of the hbas ccb structure. | |||
| 2007-12-06 | Ask for write cache and read look ahead to be turned | Jonathan Gray | |
| on if supported as per the wd changes. Some drives don't do this for us and it helps performance by a large amount. ok dlg@ | |||
| 2007-11-28 | when we probe a port send an ata inquiry to the device and cache | David Gwynne | |
| the result in the ata_port struct. use this cached inquiry data when building the replies to scsi commands rather than fetching a new copy of ata inq every time. this shrinks the code by 100 lines. it also avoids a malloc in a scsi io path, which could be issued at a time when malloc isnt guaranteed to succeed, but a real scsi io definitely should. | |||
| 2007-11-28 | make ata controllers protect their own command lists so atascsi doesnt have | David Gwynne | |
| to continually go to splbio to ensure its safe to work on them. shrinks code a little. | |||
| 2007-11-26 | implement atascsi_probe_dev and atascsi_detach_dev. they let a hba tell | David Gwynne | |
| the midlayer(s) what to do. | |||
| 2007-11-26 | drive port probes from the scsi midlayer now that it will ask the adapter | David Gwynne | |
| if a device is there before doing any scsi commands. also implement a free path for when devices are detached. software hotplug has been tested on sili, and ahci is still working according to claudio@ | |||
| 2007-11-23 | starting bits to implement hotplug of sili controllers. this adds the code | David Gwynne | |
| to clean up the atascsi stuff, and has sili call it when its going away. tested on an expresscard sili variant by kettenis@ | |||
| 2007-11-23 | use copyin and copyout to get the actual ata data in and out of the kernel | David Gwynne | |
| for the ata ioctl used by atactl. i dont know how this worked before. | |||
| 2007-11-23 | implement translation of the scsi vpd page for fetching a disks serial | David Gwynne | |
| number. lets bioctl against an atascsi disk see the serial number. continually requested by henning@ | |||
| 2007-11-23 | t10 has a whole spec on doing SCSI to ATA translation called SAT. i wish | David Gwynne | |
| id known about it when i wrote atascsi. anyway. it says we should claim SPC-3 when we fake INQUIRY. | |||
| 2007-11-16 | accept ATA ioctls so tools like atactl work on disks behind the atascsi | David Gwynne | |
| layer. i intended to write better ways to deal with disks, but i have been too slack. shame on me. this is less code than the equivilent in wdc/pciide, which amuses me greatly. | |||
| 2007-10-01 | More easy bzero() -> M_ZERO. Use 'p = malloc(sizeof(*p) ...' where | Kenneth R Westerback | |
| obvious. | |||
| 2007-04-22 | when an ata command returns an error, dont fill dmesg with messages about | David Gwynne | |
| it. returning an error to the scsi midlayer is all we need to do, which in turn will do the right thing. | |||
| 2007-04-12 | Do a security freeze lock like we do in wd(4) to deal with systems | Jonathan Gray | |
| that leave the security set on by default. "looks sane" grange@, "looks ok" pascoe@, "put it in" dlg@ | |||
| 2007-04-10 | endian fixes for the read capacity handling. | David Gwynne | |
| 2007-03-24 | Complete the right scsi_xfer when processing a disk sync request. | Christopher Pascoe | |
| 2007-03-23 | Track the ATA xfer's state more closely - may help us identify why some | Christopher Pascoe | |
| are seeing a panic at halt time. | |||
| 2007-03-23 | Really clear the device register on the flush cache command. Last commit | Christopher Pascoe | |
| adjusted the packet and identify commands. | |||
| 2007-03-23 | Clear the device register on the flush cache command, in case something | Christopher Pascoe | |
| that shouldn't care about don't care bits does care. | |||
| 2007-03-23 | Catch timed out disk commands. | Christopher Pascoe | |
| 2007-03-22 | Let atascsi issue NCQ commands if the controller supports it. | Christopher Pascoe | |
| This includes a nasty hack to reduce openings and throw away command slots if the device supports a lower queue depth than the host controller does. Yes, we're thinking about a better solution. | |||
| 2007-03-21 | A polled xfer has completed and been put by the time ata_cmd returns, so | Christopher Pascoe | |
| don't use xa->flags afterwards. | |||
| 2007-03-21 | atascsi sends h2d fis's, not d2h. | David Gwynne | |
| 2007-03-21 | replace the array of u_int8_ts for the fis/registers with a struct to make | David Gwynne | |
| it a bit easier to read. there are variations on this, but they can be defined later. | |||
| 2007-03-20 | Be sure to reset ata_xfer flags for all PACKET transfers, otherwise we | Christopher Pascoe | |
| could pick up a previous ATA_F_POLL from a previous non-data command. | |||
| 2007-03-20 | Basic FLUSH CACHE support. | Christopher Pascoe | |
| Note that the ATA spec says we're should retry after error until we see no more errors. This is not (yet) implemented. | |||
| 2007-03-20 | Tag ATAPI transfers that have no data phase correctly, otherwise the command | Christopher Pascoe | |
| isn't sent to the device. | |||
| 2007-03-20 | Oops, remove some unused variables and unmangle a command name. | Christopher Pascoe | |
| 2007-03-20 | Cap the device size we present to 2TB, just in case someone attaches | Christopher Pascoe | |
| something really big. The SCSI layer isn't yet ready for it. | |||
| 2007-03-20 | Move common completion handling into ata_exec itself. Removes a double free | Christopher Pascoe | |
| in the inquiry error paths, as the HBA will have already completed the ata_xfer with an error. Reminder and ok dlg@ | |||
| 2007-03-20 | Add support for ATA PACKET commands. This should make ATAPI cdrom drives, | Christopher Pascoe | |
| etc, just work. | |||
| 2007-03-20 | move ata command definitions from atascsi.c to atascsi.h | David Gwynne | |
| 2007-03-20 | nothing from wdc, wd, or any of the existing ata stuff pls. this gets rid | David Gwynne | |
| of the wdcreg.h include in atascsi. "feel free to remove" pascoe@ | |||
| 2007-03-20 | Request "descriptor processed" interrupts only for PIO requests (inquiry, | Christopher Pascoe | |
| etc), and request that the D2H FIS at the completion of all (DMA) commands generate an interrupt. This makes each data transfer generate one interrupt instead of two and should guarantee that the interrupt that is generated actually arrives after the command has completed. | |||
| 2007-03-20 | Calculate the residual and copy it back to the scsi_xfer, so that RW actually | Christopher Pascoe | |
| works. From dlg@ | |||
| 2007-03-20 | Add support for issuing sector read/write commands. | Christopher Pascoe | |
| 2007-03-20 | Instead of having a copy of every register that we will issue in the ata_cmd, | Christopher Pascoe | |
| simply include a pointer to the command FIS that we will issue to the device. Include another space where we can copy back an error register set from a failed command. This means that we can now build and issue arbitrary commands from atascsi, and retrieve errors back. | |||
| 2007-03-20 | Change API for struct ata_xfer allocation to move it into the device that | Christopher Pascoe | |
| atascsi will be driving, and add it to the AHCI CCB. This effectively gives us all the resources we need for a transfer in one hit, meaning that we don't need to worry about whether we will have a pool shortage or not enough CCBs. The SCSI mid layer should take care to never exceed the number of CCBs we have available, based on our sc_link.openings. | |||
| 2007-03-13 | add timeouts on ata_xfers | David Gwynne | |
| 2007-03-12 | ata counts sectors from 1, scsi counts from 0. adjust the value in the | David Gwynne | |
| read capacity completion to compensate. | |||
