d4033edb0b Reverted back to older version of ./genassym, instead of ./genassym.o
since make depend wasn't picking up any new dependencies.  However, due
to a bug in the old code, the original dependencies weren't being used, so
this version is better than the original and the lastest version.
(And is more readable as well)

2d3f6b81db This is my patched version of a busmouse driver originally by Rick Macklem
(rick@snowhite.cis.uoguelph.ca).  I am currently using it with a Microsoft
InPort busmouse, under FreeBSD Epsilon.  I hadn't planned on supporting it,
but I have patched it a few times, and I guess this is now the de facto
reference version, so send me any problems or improvements.

As the subject line says:
I can;t believe this typo is still here.

Has NOBODY used the isa_dmastart() routine for 16bit DMA?

I know I just hit the dma regs directly for the AHA1542,
and it appears that either everybody else does as well, or
they only use 8bit DMA (e.g. floppy)

Editors Note:
	The definition of DMA2_CHN was incorrectly using IO_DMA1!

98dbbc5399 genassym.c:
Remove NKMEMCLUSTERS, it is no longer define or used.

locores.s:
	Fix comment on PTDpde and APTDpde to be pde instead of pte
	Add new equation for calculating location of Sysmap
	Remove Bill's old #ifdef garbage for counting up memory,
	that stuff will never be made to work and was just cluttering
	up the file.

	Add code that places the PTD, page table pages, and kernel
	stack below the 640k ISA hole if there is room for it, otherwise
	put this stuff all at 1MB.  This fixes the 28K bogusity in
	the boot blocks, that can now go away!

	Fix the caclulation of where first is to be dependent on
	NKPDE so that we can skip over the above mentioned areas.
	The 28K thing is now 44K in size due to the increase in
	kernel virtual memory space, but since we no longer have
	to worry about that this is no big deal.

	Use if NNPX > 0 instead of ifdef NPX for floating point code.

machdep.c
	Change the calculation of for the buffer cache to be
	20% of all memory above 2MB and add back the upper limit
	of 2/5's of the VM_KMEM_SIZE so that we do not eat ALL
	of the kernel memory space on large memory machines, note
	that this will not even come into effect unless you have
	more than 32MB.  The current buffer cache limit is 6.7MB
	due to this caclulation.

	It seems that we where erroniously allocating bufpages pages
	for buffer_map.  buffer_map is UNUSED in this implementation
	of the buffer cache, but since the map is referenced in
	several if statements a quick fix was to simply allocate
	1 vm page (but no real memory) to it.

pmap.h
	Remove rcsid, don't want them in the kernel files!

	Removed some cruft inside an #ifdef DEBUGx that caused
	compiler errors if you where compiling this for debug.

	Use the #defines for PD_SHIFT and PG_SHIFT in place of
	constants.

trap.c:
	Remove patch kit header and rcsid, fix $Id$.
	Now include "npx.h" and use NNPX for controlling the
	floating point code.

	Remove a now completly invalid check for a maximum virtual
	address, the virtual address now ends at 0xFFFFFFFF so
	there is no more MAX!!  (Thanks David, I completly missed
	that one!)

vm_machdep.c
	Remove patch kit header and rcsid, fix $Id$.
	Now include "npx.h" and use NNPX for controlling the
	floating point code.

	Replace several 0xFE00000 constants with KERNBASE

276a33545e param.h:
Mark the fact that PGSHIFT and PDRSHIFT are really the same as
PG_SHIFT and PD_SHIFT, these should be collapsed some day soon.

Document that KERNBASE should really be KPTDPTDI << PDRSHIFT, for
now leave it as the constant 0xFE000000 until I make a seperate
common header file for this stuff (vmaddresses.h?)

Remove NKMEMCLUSTERS define, it was only being used to define
VM_KMEM_SIZE, so why have all the indirection.  Besides who wants
to work in CLBYTE sizes chuncks.


pmap.h:

Fix $Id$ and some other minor format clean ups.

Remove the XXX comment about NKPDE, since it now has the correct value
of 7.

Remove unused LASTPTDI and move the APTD into the very end of memory to
free up 4MB of kernel virtual address space.
Remove unused RSVDPTDI and free up 12MB of kernel virtual address space.


vmparam.h

Fix $Id$.

Increase SHMMAXPGS to 512 (2MB) now that there is room for it to be
bigger.  The XXX comment stays until the kernel moves down in memory
to free up enough space to use the proper default of 4MB.

VM_KMEM_SIZE is now a direct constant stating the size of the kernel
malloc region.  Increased the value from 3MB to 16MB.

1b5a6f1c95 Add detection code for what model of AHA154X/Z we are running on,
then use that information to fix the enhancemode features of the
1542C/CF boards by turning them off.

When doing this I found that the Buslogic 545S does NOT properly
mimic the 1542 families AHA_INQUIRE command.  It only returns 1
byte of information, when the adaptec manual clearly states that 4
bytes are to be returned.  I added a printf that explains the error
when we see a 545S for now, I tried to come up with a better solution,
but it involved to much work for now.

Bruce Evans had limited the kernel virtual address space to not include the

line of Makefile.i386.  Fixes the extra rule that gmake complains about
for machdep.o.  This fix is from Joans 0lsson.

Rework the depends and rules for assym.s and genassym so that we now use
the .depend rule for genassym.o such that if you change any header files
that are included by genassym.c the right things happen.  This is probably
what has caused more bad kernel builds than any other thing in the
Makefile.i386!

2b976dc12a ALL:
Removed patch kit headers and rcsid strings, add $Id$.

isa.c:

Removed old #ifdef notyet isa_configure code, since it will never be
used, and I have done 90% of what it attempted to.

Add conflict checking code that searchs back through the devtab's looking
for any device that has already been found that may conflict with what
we are about to probe.  Checks are mode for I/O address, memory address,
IRQ, and DRQ.  This should stop the screwing up of any device that has
alread been found by other device probes.
Print out messages when we are not going to probe a device due to
a conflict so the user knows WHY something was not found.  For example:

aha0 not probed due to irq conflict with ahb0 at 11

Now print out a message when a device is not found so the user knows
that it was probed for, but could not be found.  For example:

ed1 not found at 0x320

For devices that have I/O address < 0x100 say that they are on the
motherboard, not on isa!  The 0x100 magic number is per ISA spec.  It
may seem funny that pc0 and sc0 report as being on the motherboard, but
this is due to the fact that the I/O address used is that of the keyboard
controller which IS on the motherboard.  We really need to split the
keyboard probe from the display probe.  It is completly legal to build
a pc with out one or the other, or even with out both!

npx.c:

Return -1 from the probe routine if we are using the Emulator so
that the i/o addresses are not printed, this is the same trick used
for 486's.

Do not print the ``Errors reported via Exception 16'', and
``Errors reported via IRQ 13'' messages any more, since these just lead
to more user confusion that anything.  It still prints the message
``Error reporting broken, using 387 emulator'' so that the person is
aware that there mother board is ill.

69995035ce Removed hack that did the R_SHIFT of unsigned numbers, no longer need
to do this as I have changed to using PDTI's as the bases for the vm
system layout.

of the kernel virtual space.

Eliminate constant PDRPDROFF, now use PDTDTPI to control location of PTD,
PTDmap and PTDpde

Eliminate constant APDRPDROFF, now use APTDPTDI to control location of APTD,
APTDmap and APTDpde.

Still need to fix Sysmap location (it is still a constant).

.globl statements are now consistent with respect to <comma><space>, the
<space> being removed from all .globl statements.

Document the fillkpt macro as to what registers control what.

Fix some comments that went past column 80, and clean/line some others up.

Remove constand for _Crtat, now use KERNBASE+constant, this still needs work.

Replace constants for offsets of sigcode parameters with symbolic names
from assym.s

Mark the sigreturn() call with XXX since we use the hardcoded constant
for the system call number, this is bogus and should be a #define or
something some place!

The kernel before and after this change was verified with cmp, not one
byte changed.  These are all cosmetic clean up changes that makes the
code more correct and easier to move the kernels virtual address space
and size.

Okay, I tracked down the d*mn thing that is causing the memcpy to be
emmitted by gcc2.  In the following patch is a fix to eliminate the
one place that was causing gcc to do the memcpy in function ie_readframe
for the ie_recv_frame_desc rfd = *(ie->rframes[num]) structure copy.

I also fixed the code so that the NS (XNS) support would compile with
out error and removed the cruft #define ns_* stuff from the softc
structures (I did this a while back for all the other either drivers)

Removed the $Log$ and all of the old log stuff, that is all kept in
the cvs tree, no need to duplicate it in the file... I'll copy it
into my commit message so that it is all retained, except the
revision numbers are going to get screwed up.

It now compiles cleanly under my LINT kernel...

 * Revision 1.25  93/04/16  22:15:31  wollman
 * Fixed infinite loop in iestart() which would cause the transmitter
 * to constantly step on the Ethernet, sending the same two packets over

 * Increased transmit buffer size from 1504 to 1512, just in case I don't
 * understand how the MTU is used.

 * Unknown changes.
 *
 * Revision 1.21  93/04/12  18:29:33  wollman
 * Added multiple transmit commands.  Note that they are always queued in
 * pairs (there are only two to begin with), and the I flag is only set
 * on the second one.  This should decrease interrupt activity somewhat.
 *
 * Revision 1.20  93/04/12  15:36:05  wollman
 * Changed setup of config block to take into account difference between
 * StarLAN (10BASE-T) and Ethernet: StarLAN is Manchester, Ethernet is NRZ.

 * Last try to get large TCP windows to work...
 *
 * Revision 1.17  93/03/18  03:54:10  wollman
 * Added RNR processing as a part of receive interrupts.  Hopefully this
 * will make everything Just Work now.
 *
 * Revision 1.16  93/03/18  03:23:24  wollman
 * Still having problems with RNR conditions.  Basic problem: say we
 * set TCP window to 16k, which is a semsible value.  Then smart
 * partners will blast 16k to us, of which we can fit 8k minus a bit
 * into our buffers.  (Need to look at that memory map..)  So, we get
 * an RNR interrupt.  The problem is, what do we need to do in this case?
 * The original code doesn't work, but it doesn't hang the system either.
 *
 * Revision 1.15  93/03/18  02:37:00  wollman
 * Disabled watchdog timer.  This gets called from a timeout somewhere,
 * which is running up at softclock.  This is at a higher priority than
 * we are, so we can get interrupted in the process of receiving something
 * by the timer expiration, which is not a nice thing to have happen.
 * Question: how can we keep this functionality, but do it in sync with
 * our interrupts?  (Ugh!)
 *
 * Revision 1.14  93/03/18  02:35:46  wollman
 * Fixed some more problems with receive code---it works!
 *
 * Revision 1.13  93/03/17  20:15:59  wollman
 * Think we fixed the serious (showstopper) bugs in 1.12.
 *
 * Revision 1.12  93/03/15  17:45:39  wollman
 * Changed filtering logic dramatically to avoid the unnecessary copyin
 * for BPF or multicast routing when the packet is not for us.  (We
 * have to run in promiscuous mode in this case.)  We still need to
 * deal with the problem of allocating one mbuf per receive buffer;
 * we should be able to get away with a single mbuf for all reasonable
 * incoming packets, and using an mbuf cluster will help avoid unnecessary
 * copying of data.
 *
 * Revision 1.11  93/01/30  20:23:15  wollman
 * Fiddled with reset code to hopefully make it work better when the
 * watchdog timer expires.  Question: why does it make a difference that
 * we do the same thing through ieioctl() as we were doing before.  The
 * old code, when iereset() was called, the receive unit would completely
 * die.  But, a cycle of ifconfig ie0 down ; ifconfig ie0 up' would bring
 * things back to normal.  So, we try to mimic that now.  Grrr...
 *
 * Revision 1.10  93/01/29  17:26:50  wollman
 * Finally fixed multicast routing/BPF mb_map full problem!!!!
 * It turned out that, when we received a packet not for us, we
 * would just return from ie_readframe(), *WITHOUT* freeing the
 * mbuf that the packet was in.  So, when running in promiscuous
 * mode (i.e., multicast routing or BPF without -p), we would have
 * (on our extremely busy subnet 4) a memory leak of epic proportions.
 *
 * We now hold on to a single mbuf chain allocated in this way,
 * and the next time a packet is read, we free it.  Also, the
 * next time a packet is transmitted, we free it.  This way,
 * we never lose more than 6 mbufs total (and on average more like
 * 3).
 *
 * Revision 1.9  93/01/23  14:22:21  wollman
 * Added some StarLAN Fiber modifications from L. Jonas Olsson.
 *
 * Revision 1.8  93/01/23  14:02:34  wollman
 * Added support for IP multicasting.
 *
 * Revision 1.7  92/11/21  17:51:59  wollman
 * Added StarLAN Fiber version point to my driver.
 *
 * Revision 1.6  92/11/20  18:21:45  wollman
 * Fixed documentation, made out-of-mbuf condition an error.
 *
 * Revision 1.5  92/11/20  18:14:02  wollman
 * Move change of ethertype to host byte order so that it's after
 * bpf_mtap.  Hopefully, this will allow us to listen to incoming
 * IP packets.
 *
 * Revision 1.4  92/11/20  18:11:00  wollman
 * Added code to drop packets when we run out of mbufs rather than
 * panicking.  This should alleviate the problems observed when using tcpdump.
 *
 * Revision 1.3  92/11/14  14:12:40  wollman
 * Added BPF support code.

Subject: Re: Error reading from DAT (fwd)
Date: Mon, 11 Oct 1993 03:02:39 -40962758 (WST)

Some tapes won't do anything until you tell them to load.
Other tapes think that being asked to load is a great excuse to
make the next command return a "unit attention" (media changed) error.
Since we need to do the load, throw in a dummy instruction to cop the
error.

specifically for DEC DAT drives.

05e041e08b SYSPDROFF and SYSPDREND are now calculated using KERNBASE, KERNSIZE and
PDRSHIFT.

The SYSTEM constant that was defined in this file has been replaced
with KERNBASE from param.h.

Changed almost all # style comments to /* */ C style comments.  Several
comments cleaned up so that they make a little more since.

In the comments that describe C calling conventions to assembler routines
used a comma space sequence to seperate arguments and removed the space
between the function name and the argument list.

Removed useless comments like /* clr eax */.

Changed all comma space sequences on assemble instructions to just be comma.

Removed spaces after $ operators to make the file consistent, this may need
to change again (ie: $KERNBASE should probably be $(KERNBASE), but for now
it all seems to work just fine.)  This may become a problem with the C
pre-processor.

Changed several double blank lines to single blank lines that where used
to seperate the I/O routines, these routines are blocked enough that we
don't need double blank lines between them.

Changed sequence of I/O routines to be all input functions, all output
functions instead of just the opposite.

Moved the SHOW_A_LOT debug stuff to near the end of the file.

Changed two occurances of the constant 0xfff to NBPG-1.

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.

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.
From: bde@kralizec.zeta.org.au (Bruce Evans)

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.

>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.

...
device          cdn
to either

or

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.

Gentlemen,
I have been trying for some time now to get "netstat -r"

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

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.

Fixed wdgetctrl routines for so that it returns a meaniful string for

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.
