2015-01-27remove the second void * argument on tasks.David Gwynne
when workqs were introduced, we provided a second argument so you could pass a thing and some context to work on it in. there were very few things that took advantage of the second argument, so when i introduced pools i suggested removing it. since tasks were meant to replace workqs, it was requested that we keep the second argument to make porting from workqs to tasks easier. now that workqs are gone, i had a look at the use of the second argument again and found only one good use of it (vdsp(4) on sparc64 if you're interested) and a tiny handful of questionable uses. the vast majority of tasks only used a single argument. i have since modified all tasks that used two args to only use one, so now we can remove the second argument. so this is a mechanical change. all tasks only passed NULL as their second argument, so we can just remove it. ok krw@

2013-12-09replace workq_task_add with a task. stash teh struct in the ata xfer thingDavid Gwynne
so its now reliable.
2013-11-06teach the side-effect free drivers about the partition they are dealingTheo de Raadt
by passing a start/length in the HIB_INIT op. Then rebase all hibernate-time block offsets to be relative to the start of that partition. This simplifies things a lot. ok mlarkin
2013-10-14Use DL_SECTOBLK() instead of handrolling same calculation to getKenneth R Westerback
wdsize() return value.
2013-10-14XXsize() returns daddr_t, so calculate the return value in a daddr_tKenneth R Westerback
variable and not (usually) an int. ok miod@
2013-09-27Try harder to ensure wddump() doesn't decrement the countKenneth R Westerback
of sectors to write by one value and increment the address the next i/o will start at by a different amount.

2013-09-15Make it clearer that sc_wdc_bio.blkno is actuall a disk hardwareKenneth R Westerback
address by using the DL_BLKTOSEC() and DL_SECTOBLK() defines rather than handrolling the equivalent. Fixes current addition of a 512-byte block value (b_blkno) to a disk hardware address (DL_GETPOFFSET()). Tested on real wd(4) hardware by guenther@.

2013-01-17Add a hibernate HIB_DONE op. After the memory-side-effect driver finishesTheo de Raadt
IO to the disk, DVACT_RESUME the controller back to normal operation. That allows us to do the full DVACT_POWERDOWN sequence afterwards. ok mlarkin
2012-10-08Revamp the sequences for suspend/hibernate -> resume so that the codeTheo de Raadt
paths are reflexive. It is now possible to fail part-way through a suspend sequence, and recover along the resume code path. Split DVACT_SUSPEND by adding a new DVACT_POWERDOWN method is used after hibernate (and suspend too) to finish the job. Some drivers must be converted at the same time to use this instead of shutdown hooks (the others will follow at a later time) ok kettenis mlarkin

2011-11-15on failure, the hibernate io function should return an errno type variable,Theo de Raadt
instead of 1.
2011-11-14Use a fixed io_page for all hibernate I/O, which is needed forMike Larkin
ahci_hibernate_io, a skeleton of which is also provided in this diff. This code is from deraadt@. Tested on a few wd machines to ensure it works there as well.
2011-11-13Add some #defines for the various hibernate I/O modes, some of theMike Larkin
groundwork for *_hibernate_io functions other than wd_hibernate_io These changes were sent to me by deraadt@

2011-07-09translate the scsi UNMAP command into an equiv TRIM, and advertise UNMAPDavid Gwynne
support via the thin provisioning page. this emul is a bit unreliable since atascsi needs to allocate memory for the TRIM command to use, but we figure that the world wont end if we lose a TRIM unlink real io. ok matthew@
2011-07-09Fix fallout from my previous SCSI refactoring diff (movingMatthew Dempsky
adapter_buswidth to sc_targets): gdt(4) and atascsi(4) still used it in other ways. Apply appropriate fixes; tested on ahci(4). ok krw@
2011-07-08First batch of converting SCSI HBAs from setting saa_targets andMatthew Dempsky
saa_luns instead of adapter_buswidth and luns in the prototype link. ok dlg@, miod@
2011-07-08fill in the ata vpd page as best we can. i dont know how to fill in theDavid Gwynne
device signature so i left it blank, and the identify is the cached copy in the port structure. i filled the SAT vendor stuff in as "OpenBSD", "atascsi", osrelease.
2011-07-08provide the thin provisining vpd page if the disk does trim. only claimDavid Gwynne
to do WRITE SAME 16 for now (which is all we do).
2011-07-08macros for TRIMDavid Gwynne
2011-07-08some trim cleanups and additions.David Gwynne
use less magic numbers when check the block limits for trim. fill in the block limits vpd page with some conservative numbers about how much unmap we can do at a time (~32MB over 64 descriptors).
2011-07-06Eliminate redundant buf validation checks in xxstrategy() methods nowMatthew Dempsky
that they're implemented consistently in bounds_check_with_label(). Also, per krw's request, change bounds_check_with_label() to return 0 if the checks succeed, and change the drivers to test == -1 instead of <= 0. (Man page update to follow; intentionally omitting arch/vax/mba/hp.c from this commit because it doesn't even build currently and miod@ promises to kill it soon.) ok krw@

2011-06-30Refactor some common open/close/detach disk driver code intoMatthew Dempsky
subr_disk.c. For now just the MI disk drivers. ok deraadt@, krw@; jsing@ liked the approach too
2011-06-22Print correct function name in debug statements. ata_get_params, notKenneth R Westerback
ata_get_parms or wdc_ata_get_parms.
2011-06-21Laurence Tratt reported that his "Intel 6 Series AHCI" ahci(4) noMatthew Dempsky
longer detects his OCZ Vertex 3 after atascsi.c r1.104. For some reason, the first IDENTIFY command issued silently fails without any notification. In lieu of a better fix, workaround this for now by allowing IDENTIFY to be reissued a second time for non-PMP disks. Discussed with jmatthew@ and dlg@; ok dlg@
2011-06-20Call bufq_drain() in wddetach() instead of reimplementing the sameMatthew Dempsky
logic.
2011-06-19Use disk_lock_nointr() in the xxclose() routines so that they cannotTheo de Raadt
be interrupted. ok matthew
2011-06-19Use disk_lock/disk_unlock directly and in the same way in these drivers,Theo de Raadt
rather than using various wrappings. Convert vnd to using the sc_dk rwlock instead of using one of its own. ok matthew
2011-06-06Delete the long dead LOCKED and WANTED flags from cd(4), sd(4), andMatthew Dempsky
wd(4). They haven't been used for 10+ years, since the drivers were switched to use disk_lock() and disk_unlock() instead. No binary change.
2011-06-05Drop kernel support for the useless DIOCWLABEL ioctl and prune a lotMatthew Dempsky
of silly flag twiddling code in various disk drivers. ok deraadt@, miod@ N.B., users will need a -current disklabel(8) to be able to write new disklabels to disk now.
2011-06-03Get rid of the wlabel argument to bounds_check_with_label(). It'sMatthew Dempsky
never done anything in OpenBSD and just clutters disk drivers with silly flag handling. More cleanup to follow. ok deraadt@, millert@; no objections krw@
2011-06-02Small refactoring of atascsi and fix non-data ATA commands to not setMatthew Dempsky
ATA_F_PIO or ATA_F_READ. ok dlg@
2011-05-31Change a few of the more common disk drivers (sd, cd, wd, rd, and vnd)Matthew Dempsky
to return EBUSY if the user tries to modify an open partition's offset or size. Only sadness can result if a user tries this, and rejecting it prevents a race between sdstart() and sdstrategy(). Curiously, there was already code in the kernel and in disklabel(8) to detect/handle this, but it was effectively disabled because the disk drivers always used something like "/* sc->sc_dk.dk_openmask */ 0", and this commented out code has existed since even r1.1 in NetBSD. I had no problems building a release and messing around with disklabel(8) for a bit with this diff. Canarying the more common MI disk drivers until we gain confidence that there aren't any regressions, then we can switch the remaining drivers. "I am surprised you got me convinced that this stuff is safe" deraadt@ ok krw@
2011-05-24Move wdc_cd from ata/ata_wdc.c to ic/wdc.c so that you can compile aMatthew Dempsky
kernel without the former. Also, eliminate two dead stores in wdcattach(). ok dlg@
2011-05-08Move ata_put_xfer() from ata_xfer to atascsi_methods. It's just sillyMatthew Dempsky
to have a non-changing function pointer be part of an object rather than it's virtual method table. ok dlg@; tested on ahci(4) by Mattieu Baptiste, jasper@, and Jason Crawford; no sili(4) testers, but identical changes to ahci(4)
2011-05-05Go back to only attempting one IDENTIFY command against directlyMatthew Dempsky
attached devices as in the pre-port-multiplier code. (Devices attached via port multipliers still get multiple attempts though.) Also don't bother sleeping after the last iteration if all attempts failed. Discussed with dlg@ and Jonathan Matthew; ok dlg@
2011-04-27Fix a few off-by-1 errors in atascsi.Matthew Dempsky
ok dlg@
2011-04-18keep an eye out for wdc registers returning 0xff. if they return 0xff,Theo de Raadt
this probably means the controller is dead -- as in, a hot plug eject event. in that case, mark the driver dead and try harder to return -1 in the interrupt handler. tested by many ok dlg, miod did not object
2011-04-15Change wdc_reset_channel() to take a `no wait' argument. Pass in turn thisMiod Vallat
argument to wdcreset(), to have it skip waiting until active channels see their BUSY bit clear in the status register. Use this feature in the resume path, during the first reset operation. The first reset is supposed to only wake up the controller, and the disks don't come back until the second reset is issued, therefore waiting for them to report themselves as ready after the first reset, but before the second, is moot - and as a matter of fact some controllers, such as the AMD 754 and clones/offspring (e.g. Geode) keep the BUSY bit asserted after the first reset. Last, but not least, make sure wd@ata invokes wd_get_params() again before returning from the resume code, as we will still be using polled transfers for a short while. This causes the Lemote Yeelong to resume within less than one second, instead of the lousy 30 seconds wait between the two resets; and the wd_get_params() voodoo prevents it from getting spurious ide interrupts afterwards. wd_get_params() magic from dlg; rest of the work by yours truly after enough prodding by dlg@ and pirofti@, among others. ok deraadt@ dlg@
