| 2008-05-31 | if a dma mapping contains oddly addressed or odd length segments, then we | David Gwynne | |
| reject that mapping. this diff cleans up the mapping if it fails those diagnostics. found while looking into an issue for krw@ | |||
| 2008-04-19 | add a driver flag to force the negotiation of SATA 1 transfers | Damien Miller | |
| (1.5Gb/s). Useful where faster speeds are unstable; ok dlg@ | |||
| 2008-04-08 | pci_chipset_tag_t already_t is_t a_t pointer_t | Mark Kettenis | |
| 2008-04-08 | Make ahci detachable. Not tested as the ppb on my shitty nvidia | Jonathan Gray | |
| board doesn't seem to properly propagate expresscard interrupts. Incoporating suggestions from dlg and kettenis, ok dlg. | |||
| 2007-11-28 | the ccb lists protect themselves, so we dont have to check if we're at | David Gwynne | |
| splbio when getting and putting ata xfers. | |||
| 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 | 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@ | |||
| 2007-11-19 | When ignoring whether FR turns on or not, we should still set FRE, | Christopher Pascoe | |
| otherwise we risk leaving the port disabled after a stop/start during error recovery. ok dlg@ | |||
| 2007-11-05 | recognise (and use) ahci 1.2 controllers. | David Gwynne | |
| diff from Henrik Gustafsson | |||
| 2007-11-04 | when the ati ahci stuff is in the ide compat mode, it can sometimes cause | David Gwynne | |
| a wdc(4) controller to appear. this code disables the compat mode using some magic niklas gleaned from the linux driver. | |||
| 2007-10-27 | work around a chip bug on the ati ixp600 ahci controller. diff mostly from | David Gwynne | |
| niklas@ and tested on hardware generously provided by paul de weird. | |||
| 2007-10-01 | More easy bzero() -> M_ZERO. Use 'p = malloc(sizeof(*p) ...' where | Kenneth R Westerback | |
| obvious. | |||
| 2007-07-03 | join ahci attach code back together into one function. | David Gwynne | |
| 2007-07-03 | jmb pretends to be pci now, so i dont need to let it see ahci_softc so it | David Gwynne | |
| can provide its own attach glue to ahci. | |||
| 2007-07-02 | kettenis suggested that i can use pci_intr_map twice on the same device | David Gwynne | |
| safely, so i tried it and it worked great. i can reuse the pci_attach_args to attach ahci and now pciide to jmb without really modifying either of them. lots of code shrinks. ok jsg@ | |||
| 2007-07-02 | dont attach on jmicron parts now that jmb(4) does that for us. | David Gwynne | |
| 2007-07-02 | move ahci_softc and the prototype for ahci_attach into a header so other | David Gwynne | |
| code will be able to see it. | |||
| 2007-07-02 | pull ahci_attach apart slightly to accommodate attaching ahci(4) to things | David Gwynne | |
| other than pci(4). | |||
| 2007-06-29 | when we attach to the jmicron controllers, whack their configuration around | David Gwynne | |
| a bit. this guarantees that the controller has its ahci stuff enabled for us to use (which was previously done with magic numbers). this also configs the controller to enable a second function for pciide to attach to. | |||
| 2007-06-29 | demystify a little more of the jmicron pci control registers | David Gwynne | |
| 2007-06-29 | define away some of the magic on jmicron controllers | David Gwynne | |
| 2007-06-12 | Use SATA_SIGNATURE_ATAPI constant instead of a magic number. | Alexander Yurchenko | |
| ok dlg@ | |||
| 2007-05-30 | my (dlg says crappy) laptop requires some more delays in port_reset or | Ted Unangst | |
| things go really crazy. ok/help toby tom. dlg unhappy but ok. | |||
| 2007-05-10 | remove and hide code that isn't used. | David Gwynne | |
| found by deraadt@ | |||
| 2007-04-22 | mark the ccb used for error handling as complete when it completes. this | David Gwynne | |
| prevents dmesg spam when we return this ccb to the free list. | |||
| 2007-04-22 | unload the dmamap of the ccb used in ncq error handling once we've finished | David Gwynne | |
| with it. prevents free panics on sparc64. found by deraadt on a v215. | |||
| 2007-04-22 | prettier debug, if it is ever re-enabled, ok dlg | Theo de Raadt | |
| 2007-04-21 | disable ahci debug output. ahci is working on the majority of chipsets, | David Gwynne | |
| and its not helping us on those that arent. | |||
| 2007-04-08 | Whitespace/long line fixups. No code change. | Christopher Pascoe | |
| 2007-04-08 | Add compile-time support for coalescing command interrupts to reduce the | Christopher Pascoe | |
| overall interrupt rate. #define AHCI_COALESCE to enable. | |||
| 2007-04-06 | Wait until we have idled the port before obtaining the error CCB, so as | Christopher Pascoe | |
| to avoid tripping a KASSERT in the case when there is more than one outstanding command. ok dlg@ | |||
| 2007-04-02 | Read log page 10h to determine the NCQ error, instead of aborting all | Christopher Pascoe | |
| active commands when an error is encountered. ok dlg@ | |||
| 2007-03-31 | re-blacklist the via vt8251, there's still something fishy.. | Jasper Lievisse Adriaanse | |
| ok dlg@ | |||
| 2007-03-31 | reenable the via 8251 sata chipset. jasper proved it can work if we dont | David Gwynne | |
| do ncq, so this diff quirks it. tested by jasper@ | |||
| 2007-03-30 | the VT8251 SATA says it is ahci, but we aren't ready for it. we need to | David Gwynne | |
| quirk a few things before it will work. this blacklists that controller in ahci so pciide will be able to match it instead. found by jasper@ | |||
| 2007-03-29 | Avoid leaking a ccb in error paths. | Christopher Pascoe | |
| 2007-03-29 | Correct some minor whitespace issues. | Christopher Pascoe | |
| 2007-03-28 | While we are determining which NCQ command failed, we will need to ensure | Christopher Pascoe | |
| that we don't accidentally complete any other outstanding commands. This introduces wrappers around get_ccb and put_ccb that can temporarily stash our outstanding command state while we are issuing recovery commands. This is just the first step in NCQ recovery - for now we will reset the port on error which will permit further commands to be issued after a NCQ error. ok dlg@ | |||
| 2007-03-28 | Due to a logic inversion, we would error out any commands that had completed | Christopher Pascoe | |
| successfully and not the ones that had actually failed to complete when unable to recover from an NCQ error. ok dlg@ | |||
| 2007-03-28 | Improve output of some debugging messages. | Christopher Pascoe | |
| 2007-03-28 | Some more safety checks on ccb state. | Christopher Pascoe | |
| 2007-03-27 | attach ahci based on the pci class and interface fields, not just on a | David Gwynne | |
| list of pci devices. WARNING: this will cause your disks to change name (wd -> sd) on a supported controller. | |||
| 2007-03-23 | Turn AHCI_DEBUG back on for now, so we can see if any commands are timing | Christopher Pascoe | |
| out or erroring around the cache flush time. | |||
| 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. | |||
| 2007-03-22 | 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 | NCQ commands generate a "Set Device Bits" FIS upon completion. Enable the | Christopher Pascoe | |
| generation of interrupts when they arrive. | |||
| 2007-03-21 | Add support for issuing NCQ commands via AHCI. | Christopher Pascoe | |
| Because you cannot have NCQ commands active at the same time as standard (non-queued) commands, we must introduce a queueing scheme into the driver. This scheme ensures that a standard command is only issued to the drive when all currently active NCQ commands have finished, and that NCQ command issue is delayed when we have a pending standard command. Additionally, the queueing scheme adds a constraint to ensure that there are never more than two standard commands issued on a port at once. This should ensure that commands become active in the order they were submitted (regardless of their command slot number) both initially and when the port is reactivated after error recovery. These points mean that issuing a standard command effectively serialises the port, which may help us implement meaningful I/O barriers in the future. | |||
| 2007-03-21 | dont print if there is a device found or not, you can figure that out by | David Gwynne | |
| seeing things attach to the scsibus. ok pascoe@ | |||
| 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. | |||
| 2007-03-21 | For now, reserve one opening so we always have a CCB free to issue a soft | Christopher Pascoe | |
| reset with during error recovery. Also, ensure that that CCB has been stopped on the chip before putting it back in the pool. | |||
