* Since dlg@'s 2009 scsi midlayer refactoring the 'struct scsi_generic *cmd'krw2020-09-221-4/+4
| | | | | | | | | | | | member of 'struct scsi_xfer' has always been pointed at the 'struct scsi_generic cmdstore' member of the same instance. So nuke 'cmdstore' and remove the '*' from cmd. Take the address of cmd as required by the various casts. No intentional functional change. luna88k test by aoyama@, sparc64 test by jmatthew@ Identification of 2009's last *cmd use and ok jmatthew@

* Turning on various scsi drivers' *DEBUG options reveals that this haskrw2020-07-241-3/+3
| | | | | | | | rarely (if ever) been done. Fix many printf format errors to calm clang and gcc on amd64, i386, hppa. Missing #include, complaints if 'option <blah>DEBUG' is used in config files, etc. All in debug code.
* Move remaining scsi bus initialization info from "prototype scsi link"krw2020-07-201-5/+5
| | | | | | | fields to struct scsibus_attach_args. Nuke the struct scsi_link * (saa_sc_link) in scaibus_attach_args. Explicitly initialize each field in scsibus_attach_args variables.
* Move the adapter related items (luns, adapter, adapter_target,krw2020-07-191-6/+6
| | | | | | | adapter_buswidth, adapter_softc) from struct scsi_link to struct scsibus_attach_args. Additional compile tests by jmatthew@ (sparc64) and aoyam@ (luna88k).
* Access adapter softc via link->bus->sb_adapter_softc.krw2020-07-161-4/+4
| | | | | | | | In sparc64 autoconf access 'luns' via sb_luns and 'adapter_buswidth' via sb_adapter_buswidth. Removes last post-config uses of the copies of bus related information in scsi_link.

* If the adapter card needs to keep track of its own id on the bus, orkrw2020-07-011-8/+10
| | | | | | | | | | | the width of the bus it is providing, it should rely on info in its softc. i.e. not on info in the prototype scsi_link that is passed out for other bits of the kernel to fiddle with. Most drivers already do this. Make it so for the laggards iha(4) and siop(4). Actually use the existing softc value in wd33c93.c. No intentional functional change.

* The siop family members use various atop/ptoa dances (oosiop/osiop) orkrw2020-02-171-2/+2

| | | | | | | | | | | | | | | are first sent to target/lun, as opposed to failing to allocate a ccb (which ive already fixed). this moves the allocation and freeing of this device state in siop into the scsi_probe and scsi_free handlers. if siop cant allocate memory for a device when the midlayer is about to probe it, we dont send commands to it. if the midlayer fails to find a device at that target/lun, it asks siop to free it. simplifies the io path and avoids work during interrupts. ok deraadt@ reads good to both marco@ and krw@

* Change the scsi_cmd function member of scsi_adapter from int tokrw2010-03-231-10/+19
| | | | | | | | | | | | | 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@

| | | | | | | disks actually do queueing correctly. Keep it SIMPLE. Fixes naddy@'s magic DNES disks on siop even if dlg@'s new midlayer is active. ok marco@, tested by naddy@.
* Bring last drivers fully into the NO_CCB world by replacingkrw2009-11-221-5/+5
| | | | | | | | | | | 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@.

* The first thing done when XXX_scsi_cmd() returns TRY_AGAIN_LATER iskrw2005-12-031-6/+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.
