* Since dlg@'s 2009 scsi midlayer refactoring the 'struct scsi_generic *cmd'krw2020-09-221-5/+5
| | | | | | | | | | | | 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@
* Move remaining scsi bus initialization info from "prototype scsi link"krw2020-07-201-6/+6
| | | | | | | 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,krw2020-07-191-5/+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.krw2020-07-161-3/+3
| | | | | | | | 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.

* Expunge some Captain Obvious comments, tweak whitespace a bit, move a debugkrw2020-07-111-7/+1

* The siop family members use various atop/ptoa dances (oosiop/osiop) orkrw2020-02-171-11/+2

* Drivers that implement their own *minphys() don't need to call thekrw2020-01-251-2/+1

* Use a consistant idiom/format when declaring scsi_adapter structureskrw2020-01-231-5/+2
| | | | | | | | | | | in drivers. Terse one liners, NULLs instead of 0's, explicitly specify all members, etc. Nuke #ifdef notyet blocks related to the scsi_adapter in aic. No intentional functional change. ok tedu@

* Change the scsi_cmd function member of scsi_adapter from int tokrw2010-03-231-10/+5
| | | | | | | | | | | | | 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@

* Extend the scsi_adapter minphys() callback to take a struct scsi_link *miod2009-02-161-3/+3
