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

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.

Fixed.

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.

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)

fe3380ea19 Removed $Log$ section and patch kit headers. And here is the full
message for Bruces changes:

>From: bde@kralizec.zeta.org.au (Bruce Evans)
>Subject: fixes for fd driver

I think I've fixed some bugs in the 0.2.4 fd driver.

1. The main cause of hangs was that there was no timeout for seeks.  So
   attempting i/o with no floppy in the drive hung iff a seek was required.

2. Opens of unattached drives were allowed.  The kernel usually paniced
   soon after due to a bad pointer.

3. Some timeout functions ran at splclock() instead of splbio().  This
   may not have mattered.

4. The state machine was left in a funny state after a timeout.

5. Some function headers were new-style.

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.

That is because TIOCMGET was broken. Yes...this is known for some time
and no, we (Bruce and me) never posted it. Why? Simply because we choose
to post fixes when we fixed most of the bugs.

Anyway..now that the slip problems are coming, here is a fix for
correct TIOCMGET behaviour.

9c6b6f0846 The scsi cd.c driver is now fully dynamic. You can change the lines
in your config file from:
device          cd0
device          cd1
...
device          cdn
to either
device          cd0
or
psuedo-device   cd0

The driver now dynamically allocates all per unit dependent structs, so it
will never run out of units (okay, so now we need 32 bit device major/minor
numbers!).  It will allocate unit numbers as it needs them.

e0b6b31115 As of this revision, all known bugs have been fixed. Some of the fixes include:
1) fixed 3c503 lock-up if the thinwire cable was disconnected at boot time
2) 8013EBT boards now work (quite well!) in 16bit/16k mode
3) ED_NO_DOUBLE_BUFFERING flag now works
4) slightly higer performance (about 3%) with 16bit WD/SMC boards
5) support for WD8013WC (10BaseT) boards

   Additionally, the probe code has been reorganized to be much cleaner. This
revision of the driver is 1.25. The release notes have been updated as well.

Gentlemen,
I have been trying for some time now to get "netstat -r"
working from the 0.2.2 patchkit. I have the following solution to the
bug.

The symbol _radix_node_head needs to be added to the symbols.raw file
to enable the new routing table access. If this symbol is not present
then the old system us used which results in no routes being given. I
don't think that this justifies a patch in its own right but perhaps
could be added to a related patch sometime..

This fixes several problems.

It has almost everything that is in the FreeBSD version of Aug 22.
It is missing the bug for 2 drives and still prints <> around the

95c4372f76 From guido@gvr.win.tue.nl Sat Aug 7 06:58:04 1993
I posted some patches on the 386bsd_patchkit list to prohibit io access.
Because of a noninitialised filed in the tss, this was possible.
It is included below as the patch to machdep.c
However, when you do this *necessary* fix (security), it will be
impossible form within user space to do io.

therefor, I included another fix: when you open /dev/io, you
get the access. Of course you can rewrite it to use another minor
and thus giving access to the iospace when /dev/mem is opened, e.g.

NOTE: The /dev/io entry has not been added to /dev/MAKEDEV yet.
The patch is in NetBSD.

355f5f9e0e Fixed for DQFLQUIET flag from: Terry Lee <terry@uivlsisd.csl.uiuc.edu>
I submitted the part of patch00155 that fixes wd.c not reporting any
bad blocks.  Unfortunately, the patch created a new problem that makes new
installations using that kernel impossible.  I have included a patch below that
should fix both problems.  The fix comes from Tom Ivar Helbekkmo's wd driver
(the Norway wd driver).  I've also eliminated the use of the DKFL_QUIET flag
completely, since it is not used anymore.

Fixed wdgetctrl routines for so that it returns a meaniful string for
non IDE disk drives.  It also nolonger returns success when a drive is
not really there.

to work because they ignore IO address bits >10bits and the 3c503 asic is

780b2904e1 From Bruce Evans:
lpt doesn't work here if the printer is not turned on at boot time (this
has been reported for other systems).

lpt has a weird mapping of the flag bits vs printer numbers and MAKEDEV
does not understand this (printer 0 uses minor numbers 0-0x3f, printer 1
uses minors 0x40-0x7f, etc).

The following (simpler) problems are fixed by the patch.

lpt did not check the minor number on open, so if NLPT1 == 1 and you
try to open printer 1 then random memory above the lpt_sc array is
accessed.  I thought I had this problem for minors 1 and 2.  However,
it does not actually occur until minor 0x40.  Does anyone have lpt64?

lpt had several unnecessary && broken ANSIisms and other sloppy
declarations.
