253a42c5fc I have a new adaptec 1542CF board bought, that has the board id of 0x45.
Added it to the list of known boards and put it into the the list for
the mailbox unlock. Maybe all board-ids over 0x42 should be in the
mailbox unlock part ?

37a08e7002 sddump code is now standard, no more options SDDUMP needed in the kernel
config file.
Fixed to not use pmap_enter as this causes side effects and other
problems like a page fault while trying to do the dump.

b935223e65 Added dumps on wd0 to the end of all config lines so people know about it
and can change it.  This really won't change the kernels, it just documents
how to do the dumps on option.

4aba964ef1 New wd driver, based on Bruce Evans 'wx/altwd' driver which has passed
enough tests to be considered more stable than current driver.

Lots of work by Bruce, David G., and Guido have gone into this version, and
more is to come in the future.

Support for multiple controllers is in, but doesn't work correctly with
different controllers (IDE AND MFM), but multiple alike controllers appears
to work.

Most of the stray interrupts problems should be fixed, although you will
get a couple 'extra interrupts' when disklabeling and on startup.

33811d39ec First round of changes from John Dyson and myself to the VM system. This
set improves performance and fixes the following problems (description
from John Dyson):

1.	Growing swap space problem in both static usage and
	in situations with lots of fork/execs in heavy paging
	situations.

2.	Sparse swap space allocation (internal fragmentation.)

3.	General swap_pager slowness.

Additionally, the new swap_pager also provides hooks for multi-page
I/O that is currently being developed (in early testing phases.)

Problem #1 is a result of a problem where objects cannot be collapsed
once a pager has been allocated for them.  This problem has been solved
by relaxing the restriction by allowing the pages contained in a shadow
object's pager be copied to the parent object's pager.  The copy is
afforded by manipulating pointers to the disk blocks on the swap space.
Since an improved swap_pager has already been developed with the data
structures to support the copy operation, this new swap_pager has been
introduced.  Also, shadow object bypass in the collapse code has been
enhanced to support checking for pages on disk.  The vm_pageout daemon
has also been modified to defer creation of an object's pager when the
object's shadow is paging.  This allows efficient immediate collapsing
of a shadow into a parent object under many circumstances without the
creation of an intermediate pager.

Problem #2 is solved by the allocation data structures and algorithms
in the new swap_pager.  Additionally, a newer version of this new swap_pager
is being tested that permits multiple page I/O and mitigation of the
fragmentation problems associated with allocation of large contiguous blocks
of swap space.

Problem #3 is addressed by better algorithms and a fix of a couple of bugs
in the swap_pager.  Additionally, this new pager has a growth path allowing
multi-page inputs from disk.  Approximately 50% performance improvement can
be expected under certain circumstances when using this pager in the standard
single page mode.

(Actually, I've seen more like twice the speed in my tests. -DLG)

PF_DATAKIT (no great loss).

aaf08d94ca Make everything compile with -Wtraditional. Make it easier to distribute
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.

8b4d35c5ee 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:

fa4700b4f1 Add more strictly size check into Fdopen to eliminate
possible end-user errors.
Now:
1) on physical 1.2 can open logical 1.2, 720, 360H
2) on physical 1.44 can open logical 1.44, 720
3) on physical 360 can open logical 360
All other variants refused.
C-style improved in this check, multiply if's changed to switch.

dffff499a9 Add 360K floppy support.
More work to add 720K floppy support.
Restore good old dependance of device and floppy type.
Now:
fd?a == 1.44
fd?b == 1.2
fd?c == 720
fd?d == 360 in HD
fd?e == 360
Add more strict size check in Fdopen, not it refuse:
1) Attempt to open any type expect fd?e, if you have only 360K drive.
2) Attempt to open fd?a if you have only 1.2 drive.

1a5569c650 1) Added proc file system from Paul Kranenburg with changes from
John Dyson to make it reliably work under FreeBSD.
2) Added and enabled PROCFS in the GENERICxx and LINT kernels.
3) New execve() from me. Still work to be done here, but this version
	works well and is needed before other changes can be made. For
	a description of the design behind this, see freebsd-arch or
	ask me.
4) Rewrote stack fault code; made user stack VM grow as needed rather
	than all up front; improves performance a little and reduces
	process memory requirements.
5) Incorporated fix from Gene Stark to fault/wire a user page table
	page to fix a problem in copyout. This is a temporary fix and
	is not appropriate for pageable page tables. For a description
	of the problem, see Gene's post to the freebsd-hackers mailing
	list.
6) Tighten up vm_page struct to reduce memory requirements for it. ifdef
	pager page lock code as it's not being used currently.
7) Introduced new element to vmspace struct - vm_minsaddr; initial
	(minimum) stack address. Compliment to vm_maxsaddr.
8) Added a panic if the allocation for process u-pages fails.
9) Improve performance and accuracy of kernel profiling by putting in
	a little inline assembly instead of spl().
10) Made serial console with sio driver work. Still has problems with
	serial input, but is almost useable.
11) Added -Bstatic to SYSTEM_LD in Makefile.i386 so that kernels will
	build properly with the new ld.
