sd.c: Julian's removal of subdriver requests
st.c, scsi_tape.h: Julian's suport of compressed tape drives
Note: compressed tape drives are still not working fully.
scsiconf.h, scsi_base.c, scsi_driver.c: address problems in probes
and error console logs

2. Clean up probe messages. This is how I propose it looks for 2.1 so
if you don't like it you have my e-mail address.
|

|

2. Add "pt" (processor type) driver.
3. Add "worm" (Write Once) driver for Jordan.
|

|
|
|

|

1. Support for fixed device configuration
2. Hoisted common code to scsi_driver
3. SCSI busses dynamically allocated at boot
4. Reorg'd for LKMs

Left most current invocations as signed, though that could be wrong.
|
| |
|
|
| |
2. Use "uprintf" (instead of printf) to log the "tape not ready" message
|

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.

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).

cd.c sd.c: implement disk stats
|

|

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.

with BOUNCE_BUFFERS. This is more intuitive, and is better for future
multiplatform support. Added BOUNCE_BUFFERS option to the GENERIC and
LINT kernel config files.

cd.c:
Initialize channel info in CDIOCSETVOL ioctl.
Correct CDIOCSTOP and CDIOCEJCET ioctls to use scsi_stop_unit
instead of scsi_start_unit.
Add CDIOCALLOW and CDIOCPREVENT ioctls.
ch.h:
Return EBUSY instead of ENXIO if the device is already in use.
scsi_base.c:
Add scsi_stop_unit routine.
sd.c:
Add mising indirection through sc_link to sd_get_parms routine
when checking for media loaded.
st.c:
Return EBUSY instead of ENXIO if the device is already in use.
Clear the SDEV_WAITING flag in ststart if we do the wakeup call.

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.

Editors Note:
Line ended with comma (``,'') instead of semicolon (``;''),
this should not have effected the code.
Submitter made no comments other than it was ``simple''.

Subject: Re: Error reading from DAT (fwd)
Date: Mon, 11 Oct 1993 03:02:39 -40962758 (WST)
Some tapes won't do anything until you tell them to load.
Other tapes think that being asked to load is a great excuse to
make the next command return a "unit attention" (media changed) error.
Since we need to do the load, throw in a dummy instruction to cop the
error.
specifically for DEC DAT drives.

local fixes and makeing diffs to send back to Julian so he can update his
code.
