Reenabled "SCIOCOMAND" ioctl.
Restructured so low level drivers can easily request retries.
Added preliminary fixed SCSI devices (should be revisited before 2.1)
Added "ssc" device that can have its' (HBA, ID, LUN) set via ioctl.
Change the sc_link structure from 8 targets with 8 lun's to
16 targets with 8 lun's. Wide scsi and the ncr 825 does support 16 targets.
scsiconf.c:
move the addition of the trailing NUL's out of a then clause, they are also
needed in the else clause for an unknown device.
and all SCSI devices (except that it's not done quite the way I want). New
information added includes:
- A text description of the device
- A ``state''---unknown, unconfigured, idle, or busy
- A generic parent device (with support in the m.i. code)
- An interrupt mask type field (which will hopefully go away) so that
. ``doconfig'' can be written
This requires a new version of the `lsdev' program as well (next commit).
Changes are only effective, if NEW_SCSICONF is defined:
1) Added u_int16 quirks to struct scsi_link for device quirks.
2) Added void *devmodes to struct scsi_link for tape density modes.
3) Modified selectdev() to return first full match (with wildcard).
With this patch all device dependent configuration is done in one place
(scsiconf.c), while there were some specifications in st.c and some
hardware dependent drivers (ie. ncr.c) before.
a binary link-kit. Make all non-optional options (pagers, procfs) standard,
and update LINT to reflect new symtab requirements.
NB: -Wtraditional will henceforth be forgotten. This editing pass was
primarily intended to detect any constructions where the old code might
have been relying on traditional C semantics or syntax. These were all
fixed, and the result of fixing some of them means that -Wall is now a
realistic possibility within a few weeks.
