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.
to do this as I have changed to using PDTI's as the bases for the vm
system layout.
Eliminate constants SYSPDROFF and SYSPDREND, now use NKPTE to control the size
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.
Cleaned up tabs vs spaces after #define to make file consistent.
Removed now unused definitions of I386_PAGE_SIZE and I386_PDR_SIZE
Note That these two where unused and had the wrong values anyway!
Changed I386_KPDES to NKPDE
Changed I386_UPDES to NUPDE
Redid constant assignments of *PTDI's to be sizeable and relative.

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 1.29 93/06/20 15:40:13 wollman
* Started fixing some of the cast-qual warnings (most just commented).
*
* Revision 1.28 93/06/12 20:39:14 wollman
* Changed definition of MK_24 to silence -Wcast-qual.
*
* Revision 1.27 93/06/08 17:05:57 wollman
* Attach routine now returns void.
*
* Revision 1.26 93/06/08 16:31:21 wollman
* Deleted attempt to set watchdog timer, since we don't use it.
*
* 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
* and over again. This crashes the router (really!) and makes other
* network users very angry.
*
* Revision 1.24 93/04/14 23:57:47 wollman
* Increased transmit buffer size from 1504 to 1512, just in case I don't
* understand how the MTU is used.
*
* Revision 1.23 93/04/14 23:16:19 wollman
* Fix iestart() so that it only tries to execute a command if one was
* queued up (oops...).
*
* Revision 1.22 93/04/14 23:02:16 wollman
* 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.
*
* Revision 1.19 93/03/23 18:58:44 wollman
* Raised count of receive buffers from 32 to 48 and included analysis of
* memory usage in a comment near that definition.
*
* Revision 1.18 93/03/18 03:59:53 wollman
* 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.
*
* Revision 1.2 92/11/14 13:30:26 wollman
* Added RCS keywords
*

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.
the proper I_X86CPU in the config file the following error will occur
while building the kernel: (had to line wrap the error for this message)
../../i386/i386/machdep.c:343: #error This kernel is not configured for one \
of the supported CPUs
Remove patch kit headers, and add $Id$
This is mostly to align some more code with NetBSD.
cpu.h:
Remove the old function vs. include configuration stuff that was
ifdefed out when we went to inline functions.
Remove the define of resettodr that made it a nop, there is
already a function that makes it a nop, no need to #define one.
Remove the #defines of processor types, they are now defined
in cputypes.h, #include that file.
Add struct cpu_nameclass for support of cpu types.
frame.h:
include sys/signal.h, it will be needed in the future.
put the sigframe structure here that was in machdep.c
pcb.h:
Add multiple inclusion protection.
Add pcb_ldt and pcb_ldt_len to pcb structure, this is for the
user mode ldt.
removed patch kit headers and sccsids, add $Id$. This is a general
clean up and reallignment with NetBSD-current where possible.
genassym.c:
removed extranious include of reg.h
removed old FP_* defines that have been ifdefed out since the patch kit
removed PCB_SIGC that is not referenced anywhere
add trapframe and sigframe defines
add KERNBASE define for use in locore.s
locore.s:
include npx.h and use NNPX for turning on and off FPU
include machine/cputypes.h for the types of cpu (used in cpu_identify)
change SYSPDREND to be one higher, this is really the base of the
next area, and will be changing again next time I revise the file
Reverse the NOP defines, you now get slow NOP's by default, this
may be what is casuing us trouble with some systems. If you want
the NOPS to be null you now need to have options DUMMY_NOPS.
Now get esym from the boot blocks which don't pass it yet, and
it is not used, but this will be changing.
Move the bit_colors stuff to be in with the rest of Bruces SHOW_A_LOT
things for debugging.
Added NetBSD's CPU type probe code, we now know what type of CPU
we are running on.
Adjust kernel pde calcuation to correct for change in SYSPDREND, no
longer need the +1.
machdep.c
include npx.h and use NNPX for turning on and off FPU
include isa.h, map.h(new file), exec.h in preperation for
changes that are still in process.
Add some of the code for MACHINE_NONCONTIG that will alow us
to better map around the BIOS memory area.
Now print the version, cpu id, real memory and availiable memory
during boot.
Correct the calculation of bufpages, the code was mixing pages
and bytes, it now does the right things. Removed Bill's hack
for limiting the erronous calculation.
add the identifycpu print out code from NetBSD.
remove the definition of the sigframe struct, it belongs in
frame.h
put in printf's about syncing disks on a halt/reboot.
Change the halted message to be a little easier reading.
Clean up of the dump messages, makes the source and the output
much more readable.
Change 0,0 in several places to have spaces after the commas.
is so often reported as an error condition when it is not. We print the
size of things so for those who want to know if this happened they can
figure it out from the size information that is printed.
Change the cpu "i386" line to 2 lines:
cpu "I386_CPU"
cpu "I486_CPU"
This is so we can do real CPU classification of code.
Fix missing depend for assym.s which does depend on genassym.c
lines to match NetBSD. Added $Id$.
Added MID_MACHINE from NetBSD.
Removed definition of DELAY() for non-kernel soures.
Fixed some small english errors that had been corrected in NetBSD.
File is now identical to NetBSD's, but will be changing soon for some
of my clean up work.
machdep.o is a defined to be a target in 2 places. This was caused by
the addition of the LOAD_ADDRESS stuff. Removed the extranious target
of machdep.o.

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.
* Added software NIC reset in NE probe to work around a problem
* with some NE boards where the 8390 doesn't reset properly on

The only place I found with a printf("status %x") is in /sys/i386/isa/lpt.c,

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.

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.

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.
-Guido
Note: this should be tested first (Rich?). Tested by rgrimes
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.
going to panic shortly after this anyway. Destroys less state, and
keeps the machine from waiting for someone to smash the return key
a few times before it panics!

4. Move printf("\n"); at line 491 in "/sys/i386/isa/sio.c" to after
COM_MULTIPORT block at line 512.
From rgrimes:
The above would cause the word (multiport) with out a new line to
appear after the uart type message if you had COM_MULTIPORT enabled.
Added support of DONET({IMP,NS,ISO}) so you can now compile with options
NS and ISO, still missing some IMP code, but since the imp is old and
gone I doubt this will ever be used.
Subject: More information on "netstat -r

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
drive type. It handles BADEND144 less verbosely. It does wdgetctlr()
somewhat differently from NetBSD/FreeBSD.

Fixed printf's to be correct, since Bruce used the old ones. This driver
still prints phantom wd1's on some Maxtor and other IDE drives, I have
a patch I am sending to Bruce for checking.
wd80x3 class boards can be configured to the GENERIC kernels.
Entry was:
device ed0 at isa? port 0x280 net irq 9 iomem 0xd0000 vector edintr
Is now:
device ed0 at isa? port 0x280 net irq 5 iomem 0xd8000 vector edintr
FP and we try to call the emulator when it is not compiled in.
Removed the #if defined(i486) || defined(i387) that use to call the
panic if we did not have a math emulator.
Removed an extranious include of i386/i386/math_emu.h from math_emulate.c.
you'll get to the dump code. If you don't trust this on your disk also
add option NOT_TRUSTED, that disables the dump code, but prints out what
it WOULD do it it was going to scrible on your disk.
reinitialized between while loops. Added comments about what was going
on in the out_fdc routine.
out_fdc now returns if the direction bit is not set in time instead of
trying to wait for MRQ to get cleared.
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.
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.
profiling, and various protection checks that cause security holes
and system crashes.
* Changed min/max/bcmp/ffs/strlen to be static inline functions
- included from cpufunc.h in via systm.h. This change
improves performance in many parts of the kernel - up to 5% in the
networking layer alone. Note that this requires systm.h to be included
in any file that uses these functions otherwise it won't be able to
find them during the load.
* Fixed incorrect call to splx() in if_is.c
* Fixed bogus variable assignment to splx() in if_ed.c
* them in cpufunc.h. Modified wait loop in reset to look a little better.
* Added read for talley counters to prevent an infinite loop on old
* 8003E's if they (the counters) overflow.
asic register even if the board isn't a 3c503. This caused old 8003E's not
to work because they ignore IO address bits >10bits and the 3c503 asic is
located at +0x400....the offset was ignored by the 8003E and so the
value was written to one of the NIC registers. The bug was discovered by
Wolfgang Solfrank.
8bit or 16bit operation, and a flag to disable transmitter double buffering.
See the updated "ed.relnotes" file for information about how to set
the flags.
This should be considered the first "production" release. It still
needs a manual page, though.
argument definitions outside of the function parameter list. This is
to reduce the copious warning messages that (non-Jolitz) gcc produces.
Also fixed some bogus variable declarations and casts to make the
compiler happy.
way of doing things. There still remain several drivers that need to
be updated. Also added a compile-time option to pccons to switch the
control and caps-lock keys (REVERSE_CAPS_CTRL) - added for my personal
sanity.
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.
