5e26fb6fdf Include <sys/buf.h> so that this does't blow up with B_WRITE undefined.
I fully updated my src tree and did a `make includes' in /usr/src before
trying this fix, so I can only presume that Bruce missed something.

b36546f69a Update the linux_sendsig() handler to the new type of the 4th
arg, now unsigned long.  This was (harmlessly on i386) conflicting
with the recent 4.4Lite2 changes.

5cf588eb8b Move the elf linux_interp structure from the lkm stub to here so that it
can be referenced when the linux emulator is statically compiled into the
kernel.

9c5ee42327 Implement rudumentry support for the linux TIOC[SG]ETSERIAL ioctl's.
To complete this, some extra state has to be kept somewhere so that the
B38400 flag in Linux can be correctly translated to/from either 38400,
57600 or 115200.

e1743d02cd First attempt at FreeBSD & Linux ELF support.
Compile and link a new kernel, that will give native ELF support, and
provide the hooks for other ELF interpreters as well.

To make native ELF binaries use John Polstras elf-kit-1.0.1..
For the time being also use his ld-elf.so.1 and put it in
/usr/libexec.

The Linux emulator has been enhanced to also run ELF binaries, it
is however in its very first incarnation.
Just get some Linux ELF libs (Slackware-3.0) and put them in the
prober place (/compat/linux/...).
I've ben able to run all the Slackware-3.0 binaries I've tried
so far.
(No it won't run quake yet :)

4613eba388 Oops.. I was wrong about the change to sigsuspend. The library interface is
different to the syscall under Linux, back this out.

4f735d8edb Add support for the old-style Linux termio (not termios) TCGETA etc.
Also, LINUX_POSIX_VDISABLE is \0, FreeBSD's is 0xff. Convert between them.

This enables some more programs to run, including the Livingston Portmaster
utilities (PMtools).

d66a506616 Mega-commit for Linux emulator update.. This has been stress tested under
netscape-2.0 for Linux running all the Java stuff.  The scrollbars are now
working, at least on my machine. (whew! :-)

I'm uncomfortable with the size of this commit, but it's too
inter-dependant to easily seperate out.

The main changes:

COMPAT_LINUX is *GONE*.  Most of the code has been moved out of the i386
machine dependent section into the linux emulator itself.  The int 0x80
syscall code was almost identical to the lcall 7,0 code and a minor tweak
allows them to both be used with the same C code.  All kernels can now
just modload the lkm and it'll DTRT without having to rebuild the kernel
first.  Like IBCS2, you can statically compile it in with "options LINUX".

A pile of new syscalls implemented, including getdents(), llseek(),
readv(), writev(), msync(), personality().  The Linux-ELF libraries want
to use some of these.

linux_select() now obeys Linux semantics, ie: returns the time remaining
of the timeout value rather than leaving it the original value.

Quite a few bugs removed, including incorrect arguments being used in
syscalls..  eg:  mixups between passing the sigset as an int, vs passing
it as a pointer and doing a copyin(), missing return values, unhandled
cases, SIOC* ioctls, etc.

The build for the code has changed.  i386/conf/files now knows how
to build linux_genassym and generate linux_assym.h on the fly.

Supporting changes elsewhere in the kernel:

The user-mode signal trampoline has moved from the U area to immediately
below the top of the stack (below PS_STRINGS).  This allows the different
binary emulations to have their own signal trampoline code (which gets rid
of the hardwired syscall 103 (sigreturn on BSD, syslog on Linux)) and so
that the emulator can provide the exact "struct sigcontext *" argument to
the program's signal handlers.

The sigstack's "ss_flags" now uses SS_DISABLE and SS_ONSTACK flags, which
have the same values as the re-used SA_DISABLE and SA_ONSTACK which are
intended for sigaction only.  This enables the support of a SA_RESETHAND
flag to sigaction to implement the gross SYSV and Linux SA_ONESHOT signal
semantics where the signal handler is reset when it's triggered.

makesyscalls.sh no longer appends the struct sysentvec on the end of the
generated init_sysent.c code.  It's a lot saner to have it in a seperate
file rather than trying to update the structure inside the awk script. :-)

At exec time, the dozen bytes or so of signal trampoline code are copied
to the top of the user's stack, rather than obtaining the trampoline code
the old way by getting a clone of the parent's user area.  This allows
Linux and native binaries to freely exec each other without getting
trampolines mixed up.

c21dee177f First incarnation of our Linux emulator or rather compatibility code.
This first shot only incorporaties so much functionality that DOOM
can run (the X version), signal handling is VERY weak, so is many
other things. But it meets my milestone number one (you guessed it
- running DOOM).

Uses /compat/linux as prefix for loading shared libs, so it won't
conflict with our own libs.

Kernel must be compiled with "options COMPAT_LINUX" for this to work.

a926a37b0a Third round in syscons update.
Display update method changed, now allways write in memory buffer,
  then periodically update physical display.
Speed improvements (now > 5 times faster than the old syscons).
History now circular buffer, with changeable size.
History scroll by up/down line, up/down page, home and end.
Backtab proberly implemented.
Now space for 96 function keys, 63 allocated standard, default now
  SCO/SYSV compat again as in the old days.
New keyboard definition files ~share/syscons/keymaps/*
Misc fixes for old "hacks" that broke SCO/SYSV compat.
More that I forgot before writing this...

6378775666 First round in syscons update. Several new features has been added:
No kernel config options anymore besides keyboard language layout.
Virtual consoles are now dynamically allocated, no NCONS anymore.
Software cursor blinking/nonblinking.
Visual bell for laptops (don't beep at meetings :-).
Cursor/bell default type setable via config "flags" instead of as defines.
Cursor/bell type setable via ioctl's.
New video modes 80x30 80x60 for some laptops, and those with multisync monitors.
Scroll-lock history (length currently fixed at 100 lines).
Lots of cleanups, some only commented out for now (will goaway soon).
Support for new features in vidcontrol/kbdcontrol.
Updated manpages.

4f683116b4 Added support for many more videomodes, including graphic modes up til
320x200 256col VGA. This is nessesary for the iBCS stuff to work right.
(And we get the benefit of more video modes). Uses the videocard BIOS
to optain mode tables.
Added a "green" saver, switches off the syncs for "green" monitors.

Subject: syscons-1.3
Date: Sat, 29 Jan 94 23:33:50 MET

But here is the (hopefully) final syscons-1.3....

....

I've changed sgetc so it works as the pccons parallel
(it now uses a scgetc internally).


[
There were a couple changes that Bruce Evans sent me that were applied
to this version along with some changes that S'ren didn't incorporate
into the final version.  There will be only minor changes if anything
from this version to his final release.
