Since dlg@'s 2009 scsi midlayer refactoring the 'struct scsi_generic *cmd'

2020-09-22T19:32:51Z

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@

Nuke unused struct scsi_link members of adapter softc's where the

2020-07-22T13:16:04Z

driver successfully compiles on one or more of amd64, i386, hppa.

Move remaining scsi bus initialization info from "prototype scsi link"

2020-07-20T14:41:12Z

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,

2020-07-19T18:57:57Z

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.

2020-07-16T21:18:29Z

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.

Shuffle things around so that sc->sc_link initialization is

2020-07-02T21:59:34Z

even more concentrated just before config_found().

No need to bzero()/memset() 'struct scsibus_attach_args' variables

2020-06-27T14:29:44Z

immediately before initializing the only field in the struct.

Use SDEV_NO_ADAPTER_TARGET instead of '7' to indicate the adapter is

2020-06-24T19:35:11Z

not a target on the bus. adapter_buswidth is 2. ok dlg@ as part of a larger diff.

Nuke *_minphys() functions that either simply apply MAXPHYS or do

2020-02-13T15:11:32Z

nothing at all. MAXPHYS will be applied in minphys() and nothing at all, well, doesn't do anything. Also remove any '#define MAXPHYS' statements used solely to disguise MAXPHYS in said functions.

Drivers that implement their own *minphys() don't need to call the

2020-01-25T21:48:42Z

system minphys(). scsi_minphys() will do that and cd/sd/st will call scsi_minphys(). ok jmatthew@ as part of larger diff
