basically, reserve a new 32k space right after firstaddr,
and put the buffer space there...
the diffs are below, and are in ~cgd/sys/i386/i386 (in machdep.c)
on freefall. i obviously can't test them, so if some of you would
look the diffs over and try them out...
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.

To bring this error try to make two swap partitons on one disk:
one of the partitions will be not recognized.
Fix is simple: set uninitialized val variable.

define SHMMAXPGS where it is suppose to be, you can over ride this with
a kernel config options "SHMAXPGS=xxx", default is currently 64 pages
due to limit kernel map space.
Added at 0xFE100000 to config line as this kernel HAS to load high, and
it is the place people seem to look for samples. Also since this kernel
has so so many symbols in it also added SYMTAB_SPACE=89000.
This Makefile is for FreeBSD, not 4.3 BSD-Reno. Moved $Id$.
Added STRIP=, DBSYM=, and LOAD_ADDRESS?=
Now use LOAD_ADDRESS for linking kernel and for dbsym, added strip -x to
cut kernel size.
Added machde.o: dependency, this will be needed in the future, and for
now it does not hurt anyone.
Cleaned out conf.o: dependency, mkdep does the right things. Same for
param.c:
This is really a Merge in of NetBSD's Makefile.i386, here is the relevant

This will allow you to compile and run a freebsd kernel with shared
memory support. I haven't tested the shm*() calls yet.
You run out of page table descriptors if you specify 4Mb of sharable
memory (SHMMAXPGS=1024). I don't know what the limit is, but
SHMMAXPGS=64 works. Rich
Fixed bug that was reported (with patch) on gnu.utils.bug.
Immediate operands of the pushw instruction were being output as 32
bits, rather than the 16 bits they were supposed to be.
This is gnu lib malloc from NetBSD verbatium, here is the version info
that Chris created:
this version of GNU malloc was obtained from prep.ai.mit.edu on
9/22/1993. There was no version noted.

I think removing FINDWORK would make things clearer.
Nothing much is going to start work on the next item. However, it is
pointless to continue processing the queue for the same unready drive.
Aborting all reads and trying harder to perform all writes would be
better.
Julian writes.

The fd driver reported the wrong cylinder/head/sector numbers after an
error (ST3 is only valid after a sense-drive command), and didn't report
fs block numbers (diskerr was not used).
There was an old problem with writes to block fd devices. Try this:
1. write protect floppy in fd0.
2. tar cf /dev/fd0a /dev/null. Repeat a few times. Later writes tend to
terminate earlier.
3. un-write protect floppy.
4. repeat step 2. The writes tend to return 0, 2048, 4096, ... and then
succeed.
This was caused by a bug in vfs__bios.c. (The bug is fixed in NetBSD's
vfs_bio.c.) fd.c sets bp->b_resid to nonzero after an error. vfs__bios.c
was not initializing bp->b_resid. This causes some writes to terminate
early (e.g., writes to block devices; see spec_write()).
Related funnies:
1. Nothing tries to write the residual bytes.
2. The wd driver sets bp->b_resid to 0 after an error, so there's no
way anything else could write the residual bytes.
3. I use the block fd device for tar because the raw device seemed to
have more bugs long ago, and because it ought to be able to handle
buffering more transparently (I don't want to have to know the
device size). But spec_write() always uses the size BLKDEV_IOSIZE
== 2048 which is too small. For disks it should use the size of
one track (rounded down to meet the next track boundary or the i/o
size). Here it would help if the DIOCGPART ioctl worked. But
DIOCGPART is not implemented for floppies, and the disk size is
ignored except for partitions of type FS_BSDFFS.
added to install_notes instructions for loading distribtuion
files from a MS-DOS partition.
Minor cleanup:
fixed spelling error in inst1.install
capitalized sentences in kc.profile
reworded initial load_fd options
Extended load_fd() to support reading from the first Primary DOS
partition of the boot disk. So we have yet another medium via
which to load the FreeBSD distribution files. load_fd() has
options for listing and (if reading from the C: drive) changing
directories.
load_fd's notation assumes that the first Primary partition on
disk is the DOS drive C: (since this and only this one is mounted
by install). Otherwise, the notation may be a bit confusing.
We'll know the assumption is bad if people complain about
not finding files on their "C:" drive...
Added a device file existence check to kc.profile.
1/ fix bug where cd0a was unusable because it was compared against
the number of 2k blocks not the number of 512byte blocks.. gave
an error for all reads past 1/4 way through the disk (cd0d was ok).
2/ fix open code so that it now notices if a disk has been changed
and updates the disklabel.
3/ use the new error handling code from st.c
4/ start adding stuff to get ready for using cd_scsi_cmd from
cd_start (like is done in st and sd)
5/ more general cleanups including making dmesg report
sector size of disk.. (believe it or not SUN drives use 512 byte)
Increase the timeout from 2000 counts to 6000 counts, reported by someone
on the net (I lost the mail). This should fix some units not showing up
during probes.
The dynamically allocated struct's where not getting properly initialized
as malloc memory is NOT zerod. Added bzero's after the malloc calls
to make sure that things are initialized.
1) Install now creates a DOS partition for the first (and only the
first) Primary (un-Extended) DOS partition, providing /dev/xx0h
is available. It is mounted on /dos by default. The /etc/fstab
entry omits the dump and fsck fields, i.e.:
/dev/xx0h /dos pcfs rw
The Secondary DOS partition is not used (System ID 0xF2), because I don't
know what that is.
2) Fixed default sizes so that if someone attempts to install BSD on a 24 Mb
partition by accepting defaults, they don't end up with a 1 Mb /usr
partition (up to USRMIN Mb's). In this case, all space is split between
swap and root.
TODO:
1) Extend load_fd() to support loading distribution files directly from
the DOS partition of the hard disk.
2) Provide translated parameters to the install program (maybe
add an option to fdisk). Currently, the true geometry is used as
default, which is inappropriate for coexistence with DOS.
3) Support installing on multiple or secondary disks.

There is a typo in disktab in the NetBSD-0.9 distribution. This may be
already fixed in NetBSD-current, but it's not in any of the source that I've
sup'ed.
line 9 reads:
# sc #sectors/cylinder, nc*nt default
should read:
# sc #sectors/cylinder, ns*nt default
Added the following to the opening statement of install:
Before starting, it is important to know your hard disk's geometry
(i.e., number of cylinders, heads and sectors/track). If installing
FreeBSD on the same disk as another operating system, then the
two systems should use the same geometry. In particular, FreeBSD's
default geometry is inappropriate for MS-DOS. So in this case, the
DOS geometry should be used instead.
[This seems to be true for SCSI disks. What about IDE? With the new
boot blocks, can we ignore the disks true geometry??]
The load_fd() now initializes the `interactive' variable to -i instead
of -v (my fault).
The extract() command now rm's /tmp/cat, not /bin/cat (my fault).
Enabled floppy drive ioctl's so that disklabel on a floppy is now
quite and works correctly. This is derived from notes in Bruce Evans
lattest patches to fd.c:

>Subject: fixes for fd driver
6. I picked up some code posted the other day to implement label ioctls.
Now `disklabel fd0' works. See a comment for how to modify conf.c.

>Subject: Bad bug in kbdtables.h [FreeBSD]
I found a bug in /sys/i386/isa/kbdtables.h which contain the
different keyboard layouts for syscons. This regards all tables exept
the Danish and US. When compiling the kernel with any other keymapping
than Danish or none at all (US), you get an error that 'key_map' is undefined.
This is because there is a typo in the name of the struct containing
the tables, keymap intead of key_map.
The install disks now print the partition table data with
offsets and sizes in units of cylinders. This will help
those who want to install FreeBSD between two existing
partitions.
Renumber the section starting at the duplicate 5. section. Changed
reference to RELNOTES.FreeBSD to not have an absolute path on it since
these appear in several places!
Fixed the extract() command which I had broken attempting to implement
it without cat. It now requires cat again (no way around it unless
gunzip can accept arbitrary filename suffixes).
