* Partially revert previous mallocarray conversions that containdhill2017-04-111-2/+2

* Force openings to 1 for devices that can't do tagged i/o, i.e. morekrw2010-10-121-1/+2
| | | | | | | | | | | | | | 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@

* Change the scsi_cmd function member of scsi_adapter from int tokrw2010-03-231-15/+10
| | | | | | | | | | | | | 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@
* Zap all setting of ITSDONE in drivers that don't look at it. Nobodykrw2010-01-091-11/+1

* Bring last drivers fully into the NO_CCB world by replacingkrw2009-11-221-2/+2
| | | | | | | | | | | TRY_AGAIN_LATER uses with equivalent NO_CCB. Eliminates confusion between the two as was always intended. buf I/O's that can't be started get pushed back onto the front of the queue and retried. Others get sent back to originator as failures. No more epi-cycle looping inside the SCSI midlayer hoping the problem goes away. Various testers, no objection from miod@ as vs(4) was tested by nick@.

* Extend the scsi_adapter minphys() callback to take a struct scsi_link *miod2009-02-161-2/+2

* The first thing done when XXX_scsi_cmd() returns TRY_AGAIN_LATER iskrw2005-12-031-3/+1
| | | | | | | | to set xs->error to XS_BUSY. So it is pointless and misleading to set xs->error to XS_TIMEOUT, XS_DRIVER_STUFFUP or XS_BUSY just before returning TRY_AGAIN_LATER. No functional change.
* Major improvements to the aac(4) device driver.nate2005-11-181-1247/+2399
| | | | | | | | | | | | | - decouple the command structures from scsi structures, allowing non block oriented commands (e.g. management commands) to be built. - redesign the various command queues to remove race conditions and to allow commands from multiple sources to coexist in the system - move major processing of commands and messages to a dedicated kernel thread to avoid spending too long in the interrupt handler - add device data structures for various management commands to the header file Much code from FreeBSD

* Fix data_length values in simulationed MODE SENSE page 4 responses sokrw2005-07-031-3/+4
| | | | | | | | | | | | | that scsi_do_mode_sense() accepts them. The data_length value does not include itself, and the pg_length value in a mode page does not include itself or the page_code fields. We were +1 on the former and -2 on the latter resulting in a data_length value that was too small by one. Eliminates 'mode sense page 5 not simulated' messages. ok marco@
