| 2010-03-23 | Change the scsi_cmd function member of scsi_adapter from int to | Kenneth R Westerback | |
| void. Use XS_NO_CCB error in the scsi command (xs) to report the NO_CCB condition. Eliminates all SUCCESSFULLY_QUEUED and COMPLETE confusion and untangles the midlayer from the adapter a bit more. Eyes and some fixes by miod@ There may be some compile issues on little used (i.e. I don't have any) drivers but the change is mechanical and thus easy to remedy. ok dlg@ | |||
| 2010-02-28 | If no TOC header is read, report EIO. Even if the command finished | Kenneth R Westerback | |
| ok. Stops cdio(1) from printing bogus TOC info. ok marco@ beck@ | |||
| 2010-02-27 | Don't print sense info for ioctl's. Let the userland program decide | Kenneth R Westerback | |
| what to tell the user. Silences cdio and cdrecord while probing media. ok dlg@ marco@ deraadt@ | |||
| 2010-01-15 | Oops. Respect the various IGNORE flags when not in SCSIDEBUG mode. | Kenneth R Westerback | |
| Should quieten booting again. And thus ends n2k10. | |||
| 2010-01-15 | Abstract and merge the manual buf queue manipulating functions into | Kenneth R Westerback | |
| one place for easier debugging and maintenance. No intended functional changes. ok dlg@ | |||
| 2010-01-15 | Restore XS_BUSY delay behaviour for buf i/o. Same as for sync path. | Kenneth R Westerback | |
| ok dlg@ | |||
| 2010-01-14 | Print sense data during SCSIDEBUG again. Always print the decoded | Kenneth R Westerback | |
| data when SCSIDEBUG is set, irrespective of SCSI_SILENT. Tweak output a bit. Noticed in output generated by todd@. | |||
| 2010-01-14 | Tweak names a bit. show_mem -> scsi_show_mem, show_scsi_xs -> | Kenneth R Westerback | |
| scsi_xs_show. No functional change. | |||
| 2010-01-13 | Get new xs's with PR_ZERO to ensure all shiny new fields get | Kenneth R Westerback | |
| initialized. Bring back panics on non-NULL done and cookie fields, but put inside DIAGNOSTIC. ok dlg@ | |||
| 2010-01-13 | Cookie or done is set on entry to scsi_xs_sync(). Take panic() out | Kenneth R Westerback | |
| until we figure out why. | |||
| 2010-01-13 | when checking an xs for errors, first check if the device the xs is for | David Gwynne | |
| is dying. if so, return ENXIO. this should make detach of devices during scsi attaches less dangerous. idea (and the first version of this diff) ok deraadt@ ok krw@ | |||
| 2010-01-13 | scsi_xs_sync uses the xs cookie and done pointers, so users of scsi_xs_sync | David Gwynne | |
| cannot. panic if theyre set before scsi_xs_sync is called. question raised by and ok krw@ | |||
| 2010-01-13 | Oops. Restore decrement of xs->retries I optimized away. Not everything | Kenneth R Westerback | |
| is dlg@'s fault. ok dlg@ | |||
| 2010-01-13 | Fix SCSIDEBUG compiles. | Kenneth R Westerback | |
| Pointed out and original diff by jcs@. | |||
| 2010-01-13 | typo in panic message | joshua stein | |
| 2010-01-12 | bring sd.c r1.180 over to the other drivers now using the antisemaphore, | David Gwynne | |
| ie, dont clear the WAITING flag when restarting the xxstart loops. | |||
| 2010-01-12 | dont let the antisemaphore clear the WAITING flag so NO_CCB doesnt cause | David Gwynne | |
| us to loop forever. follow sdstart through to to an adapters scsi_cmd handler and assume that handler returns NO_CCB to enjoy the bug in full. ok kettenis@ krw@ beck@ | |||
| 2010-01-11 | dlg@ lost the SCSI_IGNORE_ILLEGAL_REQUEST flag on all SYNCHRONIZE_CACHE | Kenneth R Westerback | |
| commands. Noticed & fix tested by halex@. ok dlg@ | |||
| 2010-01-11 | Bring mutex protections to ststart, cdstart and ssstart, as already | Kenneth R Westerback | |
| done in sd. Make names consistant across all three. ok dlg@ tested (cd) & ok beck@ | |||
| 2010-01-11 | Be as careful with sd/cd buf queue manipulations as was found necessary for | Kenneth R Westerback | |
| st's queue manipulations. i.e. ensure b_actb is correctly updated as the queue becomes empty or has an i/o requeued on it. Tested on claudio@'s backup crashing box. ok dlg@ beck@ | |||
| 2010-01-11 | Add mutex around work consuming loop in sdstart - this ensures that only | Bob Beck | |
| one thread will be grabbing xs's at a time and dequeuing work, but avoids a race between notification there is work to do and exiting the loop releasing the xs's. Fixes problem noticed by claudio where usb disks would hang with the new minty dlg midlayer. ok krw@, dlg@, tested by claudio@ | |||
| 2010-01-10 | Restore delay on XS_BUSY result, just in case it is needed somewhere. Polish | Kenneth R Westerback | |
| logic to eliminate FALLTHROUGH craziness. ok marco@ dlg@ | |||
| 2010-01-10 | Set ITSDONE in scsi_done() and zap trivial instances of setting it | Kenneth R Westerback | |
| in the drivers just before calling scsi_done(). ok dlg@ beck@ | |||
| 2010-01-09 | panic with a nice message if scsi_xs_sync_done gets called twice | David Gwynne | |
| rather than generating a fluffy printf. | |||
| 2010-01-09 | dont try to prevent multiple concurrent runs of a devices start routine | David Gwynne | |
| by setting flags around the loop. there is a race which can prevent necessary work being completed by any of the currently running instances of xxstart. the caveat with the removal of this code is because multiple xxstarts can be running at the same time they can cause io reordering, but that is less of a problem than no io. found by and fix tested by claudio@ debugged with krw@ claudio@ beck@ deraadt@ | |||
| 2010-01-09 | always try to restart io on a device when an opening is made available from | David Gwynne | |
| scsi_xs_put. | |||
| 2010-01-07 | warn if scsi_done has been called twice on an xs in the scsi_xs_sync path | David Gwynne | |
| rather than panic. ok krw@ | |||
| 2010-01-05 | only call disk_unbusy when we're finished with the io (or we're requeuing | David Gwynne | |
| it when we hit NO_CCB). retried io would call unbusy twice before this change. noticed by deraadt@ | |||
| 2010-01-04 | nothing in the midlayer cares about ITSDONE anymore. if a command is done, | David Gwynne | |
| the adapter will call scsi_done on it. | |||
| 2010-01-04 | introduce scsi_xs_sync. this will synchronously execute a scsi_xfer | David Gwynne | |
| and do the appropriate sleeps, retries, error processing, and finally returns an errno style value to the caller. this cuts scsi_scsi_cmd, the ioctl code, sd_flush, and scsi_inquiry over to scsi_xs_sync. ok krw@ | |||
| 2010-01-03 | disk cache mode page | David Gwynne | |
| 2010-01-03 | scsi_done sets ITSDONE, we dont have to do it. | David Gwynne | |
| 2010-01-02 | move the buf handling from using scsi_scsi_cmd over to scsi_xs_exec. i | David Gwynne | |
| think this is the last chunk of code using a buf pointer in the scsi_xfer now. this has not been tested due to a lack of hardware anywhere. if there are problems please report them as soon as possible. ok krw@ miod@ | |||
| 2010-01-01 | If you want to use atomic ops, you need to #include the proper files instead | Miod Vallat | |
| of relying upon other headers bringing it in for you. | |||
| 2010-01-01 | deck chair shuffling | David Gwynne | |
| 2010-01-01 | split the flags used in a scsi_link structure to represent its state at | David Gwynne | |
| runtime out into a separate state variable. only operate on the state bits with atomic ops. introduce the DYING state so things that sleep can figure out if they should keep going or not. | |||
| 2009-12-26 | move st over to the new midlayer. | David Gwynne | |
| much testing and debugging from krw@ his diff was a nice christmas present | |||
| 2009-12-16 | nothing needs to see cd_softc except the driver, so move it into cd.c | David Gwynne | |
| ok marco@ guenther@ | |||
| 2009-12-13 | remove #ifdef CDDA bits cos nothing in cd.c uses it and nothing i can find | David Gwynne | |
| defines it. | |||
| 2009-12-13 | prefix all softc members with sc_, not just most of them. | David Gwynne | |
| 2009-12-13 | use sc consistently as the name of the pointer to the softc variable, not | David Gwynne | |
| cd. | |||
| 2009-12-12 | move cd(4) from using scsi_scsi_cmd over to scsi_xs_exec for doing io. | David Gwynne | |
| this brings it in line with the new midlayer changes. mostly borrowed from sd(4) changes. tested by krw@ and me ok krw@ | |||
| 2009-12-09 | Nuke stray comment referencing deceased TRY_AGAIN_LATER that dlg@ | Kenneth R Westerback | |
| snuck back in. Noticed by kettenis@. | |||
| 2009-12-07 | Re-enable SCSIDEBUG display of commands and data. Original diff | Kenneth R Westerback | |
| from dlg@, tweaking by me to make it compile. ok dlg@ | |||
| 2009-12-06 | Nuke SCSI_URGENT after removing its only use, in ncr53c9x.c. That use | Kenneth R Westerback | |
| was to try to play dangerous games with tagged queuing. ok marco@ | |||
| 2009-12-06 | SCSI_USER is deprecated. the ioctl handlers arent special with regard to | David Gwynne | |
| the midlayer. | |||
| 2009-12-06 | consistently refer to the softc pointer as sc, not sd. | David Gwynne | |
| 2009-12-06 | biodone must be called at splbio. | David Gwynne | |
| 2009-12-06 | nitems(array) is prettier than sizeof(array)/sizeof(array[0]) | David Gwynne | |
| 2009-12-06 | whitespace tweaks | David Gwynne | |
