Description:
Old wt driver is too incomplete and buggy.
It does not support Archive controllers, BSD-like
tape ioctls, multiple tape controllers, different
tape density etc.
Fix:
This driver is a replacement of the old one.
It was not tested on different controllers, though.
This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

the second set of changes in a move towards getting devices to be
totally dynamic.
this is only the devices in i386/isa
I'll do more tomorrow.
they're completely masked by #ifdef JREMOD at this stage...
the eventual aim is that every driver will do a SYSINIT
at startup BEFORE the probes, which will effectively
link it into the devsw tables etc.
If I'd thought about it more I'd have put that in in this set (damn)
The ioconf lines generated by config will also end up in the
device's own scope as well, so ioconf.c will eventually be gutted
the SYSINIT call to the driver will include a phase where the
driver links it's ioconf line into a chain of such. when this phase is done
then the user can modify them with the boot: -c
config menu if he wants, just like now..
config will put the config lines out in the .h file
(e.g. in aha.h will be the addresses for the aha driver to look.)
as I said this is a very small first step..
the aim of THIS set of edits is to not have to edit conf.c at all when
adding a new device.. the tabe will be a simple skeleton..
when this is done, it will allow other changes to be made,
all teh time still having a fully working kernel tree,
but the logical outcome is the complete REMOVAL of the devsw tables.
By the end of this, linked in drivers will be exactly the same as
run-time loaded drivers, except they JUST HAPPEN to already be linked
and present at startup..
the SYSINIT calls will be the equivalent of the "init" call
made to a newly loaded driver in every respect.
For this edit,
each of the files has the following code inserted into it:
obviously, tailored to suit..
----------------------somewhere at the top:
#ifdef JREMOD
#include <sys/conf.h>
#define CDEV_MAJOR 13
#define BDEV_MAJOR 4
static void sd_devsw_install();
#endif /*JREMOD */
---------------------somewhere that's run during bootup: EVENTUALLY a SYSINIT
#ifdef JREMOD
sd_devsw_install();
#endif /*JREMOD*/
-----------------------at the bottom:
#ifdef JREMOD
struct bdevsw sd_bdevsw =
{ sdopen, sdclose, sdstrategy, sdioctl, /*4*/
sddump, sdsize, 0 };
struct cdevsw sd_cdevsw =
{ sdopen, sdclose, rawread, rawwrite, /*13*/
sdioctl, nostop, nullreset, nodevtotty,/* sd */
seltrue, nommap, sdstrategy };
static sd_devsw_installed = 0;
static void sd_devsw_install()
{
dev_t descript;
if( ! sd_devsw_installed ) {
descript = makedev(CDEV_MAJOR,0);
cdevsw_add(&descript,&sd_cdevsw,NULL);
#if defined(BDEV_MAJOR)
descript = makedev(BDEV_MAJOR,0);

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.
Thanks to all who helped to test it on the following hardware:

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

Description:
Old wt driver is too incomplete and buggy.
It does not support Archive controllers, BSD-like
tape ioctls, multiple tape controllers, different
tape density etc.
Fix:
This driver is a replacement of the old one.
It was not tested on different controllers, though.
This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker

wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

Description:
Old wt driver is too incomplete and buggy.
It does not support Archive controllers, BSD-like
tape ioctls, multiple tape controllers, different
tape density etc.
Fix:
This driver is a replacement of the old one.
It was not tested on different controllers, though.
This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait

4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange

wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

the second set of changes in a move towards getting devices to be
totally dynamic.
this is only the devices in i386/isa
I'll do more tomorrow.
they're completely masked by #ifdef JREMOD at this stage...
the eventual aim is that every driver will do a SYSINIT
at startup BEFORE the probes, which will effectively
link it into the devsw tables etc.
If I'd thought about it more I'd have put that in in this set (damn)
The ioconf lines generated by config will also end up in the
device's own scope as well, so ioconf.c will eventually be gutted
the SYSINIT call to the driver will include a phase where the
driver links it's ioconf line into a chain of such. when this phase is done
then the user can modify them with the boot: -c
config menu if he wants, just like now..
config will put the config lines out in the .h file
(e.g. in aha.h will be the addresses for the aha driver to look.)
as I said this is a very small first step..
the aim of THIS set of edits is to not have to edit conf.c at all when
adding a new device.. the tabe will be a simple skeleton..
when this is done, it will allow other changes to be made,
all teh time still having a fully working kernel tree,
but the logical outcome is the complete REMOVAL of the devsw tables.
By the end of this, linked in drivers will be exactly the same as
run-time loaded drivers, except they JUST HAPPEN to already be linked
and present at startup..
the SYSINIT calls will be the equivalent of the "init" call
made to a newly loaded driver in every respect.
For this edit,
each of the files has the following code inserted into it:
obviously, tailored to suit..
----------------------somewhere at the top:
#ifdef JREMOD
#include <sys/conf.h>
#define CDEV_MAJOR 13
#define BDEV_MAJOR 4
static void sd_devsw_install();
#endif /*JREMOD */
---------------------somewhere that's run during bootup: EVENTUALLY a SYSINIT
#ifdef JREMOD
sd_devsw_install();
#endif /*JREMOD*/
-----------------------at the bottom:
#ifdef JREMOD
struct bdevsw sd_bdevsw =
{ sdopen, sdclose, sdstrategy, sdioctl, /*4*/
sddump, sdsize, 0 };
struct cdevsw sd_cdevsw =
{ sdopen, sdclose, rawread, rawwrite, /*13*/
sdioctl, nostop, nullreset, nodevtotty,/* sd */
seltrue, nommap, sdstrategy };
static sd_devsw_installed = 0;
static void sd_devsw_install()
{
dev_t descript;
if( ! sd_devsw_installed ) {
descript = makedev(CDEV_MAJOR,0);
cdevsw_add(&descript,&sd_cdevsw,NULL);
#if defined(BDEV_MAJOR)
descript = makedev(BDEV_MAJOR,0);

If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

Description:
Old wt driver is too incomplete and buggy.
It does not support Archive controllers, BSD-like
tape ioctls, multiple tape controllers, different
tape density etc.
Fix:
This driver is a replacement of the old one.
It was not tested on different controllers, though.
This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait

4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange

wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,

Description:
Old wt driver is too incomplete and buggy.
It does not support Archive controllers, BSD-like
tape ioctls, multiple tape controllers, different
tape density etc.
Fix:
This driver is a replacement of the old one.
It was not tested on different controllers, though.
This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning

Description:
Old wt driver is too incomplete and buggy.
It does not support Archive controllers, BSD-like
tape ioctls, multiple tape controllers, different
tape density etc.
Fix:
This driver is a replacement of the old one.
It was not tested on different controllers, though.
This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape

wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation

wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation

pwoperly. Use raw interface instead.

Description:
Old wt driver is too incomplete and buggy.
It does not support Archive controllers, BSD-like
tape ioctls, multiple tape controllers, different
tape density etc.
Fix:
This driver is a replacement of the old one.
It was not tested on different controllers, though.
This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

wt.c - version 1.3

E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait

4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange

5) Tape density switching added.

wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

Description:
Old wt driver is too incomplete and buggy.
It does not support Archive controllers, BSD-like
tape ioctls, multiple tape controllers, different
tape density etc.
Fix:
This driver is a replacement of the old one.
It was not tested on different controllers, though.
This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker

wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.
Thanks to all who helped to test it on the following hardware:

7) It's possible to use the tape with "default density",

Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

Description:
Old wt driver is too incomplete and buggy.
It does not support Archive controllers, BSD-like
tape ioctls, multiple tape controllers, different
tape density etc.
Fix:
This driver is a replacement of the old one.
It was not tested on different controllers, though.
This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:

b - Long block size flag. With this bit set,
the driver will perform all i/o operations

Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

Description:
Old wt driver is too incomplete and buggy.
It does not support Archive controllers, BSD-like
tape ioctls, multiple tape controllers, different
tape density etc.
Fix:
This driver is a replacement of the old one.
It was not tested on different controllers, though.
This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker

wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.
Thanks to all who helped to test it on the following hardware:

This driver is a replacement of the old one.
It was not tested on different controllers, though.
This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker

wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.
Thanks to all who helped to test it on the following hardware:

Description:
Old wt driver is too incomplete and buggy.
It does not support Archive controllers, BSD-like
tape ioctls, multiple tape controllers, different
tape density etc.
Fix:
This driver is a replacement of the old one.
It was not tested on different controllers, though.
This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
Block interface (writing blocks less than 2048 bytes) is not functioning

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait

4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.

5) Tape density switching added.
6) The status of the process, blocked on the tape operation,

wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

b - Long block size flag. With this bit set,
the driver will perform all i/o operations

Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV

Block interface (writing blocks less than 2048 bytes) is not functioning

Description:
Old wt driver is too incomplete and buggy.
It does not support Archive controllers, BSD-like
tape ioctls, multiple tape controllers, different
tape density etc.
Fix:
This driver is a replacement of the old one.
It was not tested on different controllers, though.
This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
5) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
6) Tape density switching added.
7) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker

wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation

wt.c - version 1.3
from:
Sergey Ryzhkov, Serge Vakulenko
E-mail: <sir@kiae.su>, <vak@zebub.msk.su>
This is the streamer tape driver for 386bsd and FreeBSD, which
supports Wangtek and Archive compatible QIC-02/QIC-36 controllers.
It was developed as a replacement of the old Wangtek tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
2) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.

until they finish. The next open() will wait for it instead.
4) Use of WTQICMD ioctl is limited to ERASE and RETENS operations.
This prevents the user from locking the tape driver by strange
tape operations.
5) Tape density switching added.
6) The status of the process, blocked on the tape operation,
is displayed at the WCHAN column of the `ps' command as:
wtread reading data from the tape
wtwrite writing data to the tape
wtrfm reading the tape marker
wtwfm writing the tape marker
wtrew rewinding the tape
wterase doing WTQICMD ERASE operation
wtretens doing WTQICMD RETENS operation
wtorew doing MTIOCTOP REW/OFFL operation
wtorfm doing MTIOCTOP FSF operation
wtowfm doing MTIOCTOP WEOF operation
7) It's possible to use the tape with "default density",
useful for devices which don't support density switching
or do automatic format determination.
8) Some controllers support only 1024 block length.
Setting WT_BSIZE bit in device minor number turns on this mode.
Minor number structure:
0bfffuuu
Fields:
uuu - Unit number. It's possible to install
up to three tape controllers on the same machine,
using DRQs 1..3. Hence, unit number can lie
in range 0..2.
fff - Tape format number:
0 - /dev/rwt0 - default density (auto select)
1 - /dev/rwt0a - QIC 11 (obsolete)
2 - /dev/rwt0b - QIC 24 (60 megabytes)
3 - /dev/rwt0c - QIC 120 (120 megabytes)
4 - /dev/rwt0d - QIC 150 (150 megabytes)
5 - /dev/rwt0e - QIC 300 (300 megabytes?)
6 - /dev/rwt0f - QIC 600 (600 megabytes?)
b - Long block size flag. With this bit set,
the driver will perform all i/o operations
with the controller using 1024-byte
blocks, instead of 512 ones.
Some controllers need it (CMS for example).
If you Wangtek controller does not stream well,
you can try to use /dev/rWt0 device instead
of /dev/rwt0 (uncomment needed lines in /dev/MAKEDEV
to create it).
Block interface (writing blocks less than 2048 bytes) is not functioning
pwoperly. Use raw interface instead.
Thanks to all who helped to test it on the following hardware:

Description:
Old wt driver is too incomplete and buggy.
It does not support Archive controllers, BSD-like
tape ioctls, multiple tape controllers, different
tape density etc.
Fix:
This driver is a replacement of the old one.
It was not tested on different controllers, though.
This is the streamer tape driver for 386bsd and FreeBSD,
which supports Wangtek and Archive controllers.
It was developed as a replacement of the old Wangtek
tape driver from CMU.
In comparison with the CMU driver, this version has the following enhancements:
1) Support for Archive SC402 and SC499 tape controllers added.
2) Support for up to three tape controllers on the same machine.
3) Support for BSD-style ioctls MTIOCGET, MTIOCTOP.
Mt command now works adequately with this driver.
4) Asynchronous REWIND and FSF operations, close() will not wait
until they finish. The next open() will wait for it instead.

the second set of changes in a move towards getting devices to be
totally dynamic.
this is only the devices in i386/isa
I'll do more tomorrow.
they're completely masked by #ifdef JREMOD at this stage...
the eventual aim is that every driver will do a SYSINIT
at startup BEFORE the probes, which will effectively
link it into the devsw tables etc.
If I'd thought about it more I'd have put that in in this set (damn)
The ioconf lines generated by config will also end up in the
device's own scope as well, so ioconf.c will eventually be gutted
the SYSINIT call to the driver will include a phase where the
driver links it's ioconf line into a chain of such. when this phase is done
then the user can modify them with the boot: -c
config menu if he wants, just like now..
config will put the config lines out in the .h file
(e.g. in aha.h will be the addresses for the aha driver to look.)
as I said this is a very small first step..
the aim of THIS set of edits is to not have to edit conf.c at all when
adding a new device.. the tabe will be a simple skeleton..
when this is done, it will allow other changes to be made,
all teh time still having a fully working kernel tree,
but the logical outcome is the complete REMOVAL of the devsw tables.
By the end of this, linked in drivers will be exactly the same as
run-time loaded drivers, except they JUST HAPPEN to already be linked
and present at startup..
the SYSINIT calls will be the equivalent of the "init" call
made to a newly loaded driver in every respect.
For this edit,
each of the files has the following code inserted into it:
obviously, tailored to suit..
----------------------somewhere at the top:
#ifdef JREMOD
#include <sys/conf.h>
#define CDEV_MAJOR 13
#define BDEV_MAJOR 4
static void sd_devsw_install();
#endif /*JREMOD */
---------------------somewhere that's run during bootup: EVENTUALLY a SYSINIT
#ifdef JREMOD
sd_devsw_install();
#endif /*JREMOD*/
-----------------------at the bottom:
#ifdef JREMOD
struct bdevsw sd_bdevsw =
{ sdopen, sdclose, sdstrategy, sdioctl, /*4*/
sddump, sdsize, 0 };
struct cdevsw sd_cdevsw =
{ sdopen, sdclose, rawread, rawwrite, /*13*/
sdioctl, nostop, nullreset, nodevtotty,/* sd */
seltrue, nommap, sdstrategy };
static sd_devsw_installed = 0;
static void sd_devsw_install()
{
dev_t descript;
if( ! sd_devsw_installed ) {
descript = makedev(CDEV_MAJOR,0);
cdevsw_add(&descript,&sd_cdevsw,NULL);
#if defined(BDEV_MAJOR)
descript = makedev(BDEV_MAJOR,0);
bdevsw_add(&descript,&sd_bdevsw,NULL);
#endif /*BDEV_MAJOR*/
sd_devsw_installed = 1;
}
}
#endif /* JREMOD */
