2011-01-26Add port multiplier support, has been in snaps for a while with no reportedDale Rahn
issues. No actual OKs, but general acknowledgement and 'get it in' from several.

2010-12-30The NVIDIA MCP89 SATA controller found on the 2010 Apple 13" MacBook ProMark Kettenis
can't address block 0xffffffff in LBA mode, at least in combination with the Hitachi HTS545032B9SA02 and HTS545050B9SA02 drives that Apple ships. So use LBA48 mode from that block onwards. ok marco@, deraadt@, miod@

2010-11-06If the dma_init callback function returns with EINVAL, fall back to PIO.Mark Kettenis
This will be used to work around bugs in certain pciide(4) controllers. From NetBSD. ok jsg@, krw@, deraadt@
2010-10-12Force openings to 1 for devices that can't do tagged i/o, i.e. moreKenneth R Westerback
than 1 i/o active at once. This reduces the chances that concurrent i/o's for such devices will confuse the device or the adapter code. It also eliminates a reason for adapter code to maintain its own queues. Tweak all drivers that fake INQUIRY results to set the SID_CmdQue flag, thus continuing to claim to be able to do tagged i/o. Positive feedback from matthew@ and marco@ for an earlier version. ok dlg@

2010-09-19move the ncq depth calculation into atascsi_probe where it belongs. byDavid Gwynne
default we now only give devices 1 openings unless both the adapter and device support ncq and a queue depth greater than one. tested by josh elsasser, who always seems to get hurt when i change the openings handling in atascsi. ok krw@

2010-09-08Introduce a disk_lookup() function which calls device_lookup(), beforeJoel Sing
verifying that the resulting device is present on the disklist. This avoids a race whereby the disk driver can be accessed as soon as the softc has been allocated, but before the disk has completed initialisation and has called disk_attach() (up until this point dk_label is still a null pointer). Cut cd(4), sd(4) and wd(4) across to disk_lookup(). All callers of disk_attach() need to be tested and cut over in due course. ok deraadt@ krw@
2010-09-08Store a struct device pointer within struct disk and populate this whenJoel Sing
disk_attach() is called by the device driver. We will be building on this shortly. ok deraadt@ krw@

ok krw@ marco@ matthew@
2010-09-01make struct bufq a member of the softc for devices that use it,David Gwynne
rather than it being a pointer to something that needs to be allocated at attach. since all these devices need a bufq to operate, it makes sense to have it allocated as part of the softc and get bufq_init to just initialise all its fields. it also gets rid of the possibility that you wont be able to allocate the bufq struct during attach, which is something you dont want to happen. secondly, it consistently implements a split between wrapper functions and the per discipline implementation of the bufq handlers. it consistently does the locking in the wrappers rather than doing half in the wrappers and the other half in the implementations. it also consistently handles the outstanding bufq bq pointer in the wrappers. this hides most of the implementation inside kern_bufq.c. the only stuff left in buf.h is for the bits each implementation needs to put inside struct buf. tested by thib@ krw@ and me ok thib@ matthew@ no objection from krw@

2010-07-27Add scsi_cmd_rw_decode() for decoding any SCSI READ or WRITE command,Matthew Dempsky

2010-07-22Give the drive a little bit more time to complete the STANDBY IMMED command.Mark Kettenis
The ATA spec seems to suggest it may take up to 30s. This seems a little bit long. To quote Theo: "by that time some drives have probably parked their own heads in boredom". But it shouldn't hurt unless your drive is seriously broken. Makes some laptops suspend much better. ok deraadt@

2010-05-26Reintroduce bufqs. A few changes since it was backed out after some goodThordur I. Bjornsson
comments from dlg@. No need for a separate bufq.h, keep all of in buf.h; As requested by kittens and deraadt. Only sd(4) and wd(4) for now. The rest of the drivers will be converted soon, also other goodies like heuristics for sd(4) for selecting the bufq type and the death of disksort() are forthcoming.

gets rid of #include <sys/dkio.h> in sys/ioctl.h and adds #include <sys/dkio.h> to the places that actually want and use the disk ioctls. this became an issue when krw@'s X build failed when he was testing a change to dkio.h. tested by krw@ help from and ok miod@

2010-04-23the SAT spec from t10.org defines messages for tunnelling ATA commands overDavid Gwynne
SCSI when you're talking to a scsi to ata translation layer (satl). this implements the ata command ioctl handler in scsi_ioctl.c that wraps the ata command requests up in these scsi commands and then issues them against the hardware. this cuts atascsi over to interpreting these scsi commands rather than the ioctls directly. this should allow mpi users (with a relatively recent firmware) to use atactl against their SATA disks. i cant test cos my mpi(4) parts are too old to either support these scsi commands or too old to take recent firmwares. ok marco@ @krw tested by krw@ and me on ahci/atascsi
2010-04-22cut atascsi over to providing and using iopools. this gets rid of NO_CCBDavid Gwynne
and makes the ioctl path more reliable on busy disks by allowing it to sleep in the runqueue for an io to use. mk@ did the original diff and figured most of the problems out. ok mk@

2010-04-11Send "STANDBY IMMEDIATE" command to ATA disks upon suspend. For this to work,Mark Kettenis
pciide(4) needs to formward DVACT_SUSPEND and DVACT_RESUME events to its children, so do that. Gets rid of the nasty "click" sound from the disk on many laptops. ok marco@, jsg@
