d98667394d make obj before building the aic7xxx assembler. This puts the object
files in the right place.

The clean rule still isn't quite right since currently config doesn't
allow the specification of arbitrary clean rules.

4c024bbdf8 Improved CPU identification and initialization routines. This
supports All Cyrix CPUs, IBM Blue Lightning CPU and NexGen (now AMD)
Nx586 CPU, and initialize special registers of Cyrix CPU and msr of
IBM Blue Lightning CPU.

If revision of Cyrix 6x86 CPU < 2.7, CPU cache is enabled in
write-through mode.  This can be disabled by kernel configuration
options.

e4107dcf00 This mega-merge brings Matt Thomas' 960801 FDDI driver (almost) up
to -current.

Thanks goes to Ulrike Nitzsche <ulrike@ifw-dresden.de> for giving me
a chance to test this.  Only the PCI driver is tested though.

One final patch will follow in a separate commit.  This is so that
everything up to here can be dragged into 2.2, if we decide so.

3b20426160 Add the ex driver (Intel EtherExpress Pro/10).
I have no idea if this works since I don't have one of the cards to test.
I also don't know what the LINT and GENERIC entries should look like,
so I just made up some values for now and left them commented out.
Someone who knows the factory settings for a Pro/10, please contact me!

2fa4e5a7fc Set a more explicit #include path for building aix7xxx_asm, otherwise it
uses /usr/include/sys/*, which may point to a different build tree.  I'm
not sure that this is necessary, but there was a question mark over what
/usr/include/sys points to when building the "user mode" binaries in the
kernel code, especially when building the smp tree.

I suspect that the "right" line here is to use ${INCLUDES}, but that
causes warnings about unused static inline functions in stdio.h and ctype.h

6a90d9750d Finally a start at sharing the kdb controller routines between
syscons and psm, curtesy Kazutaka Yokota with minor changes by
me. This contains an update of the psm driver as well.
This also fixes the breakage that I introduced to the psm driver by
making syscons poll for keyboard events in the atempt to fix the
hanging keyboard problem.

It works perfectly for me, and I'd like to hear from all that
have had keyboard/ps/2 mouse problems if this is the cure...

b3ac88f13f New vx driver for:

        3COM 3C900 Etherlink XL PCI and
        3COM 3C905 Fast Etherlink XL PCI.

This driver is based on OpenBSD's driver. I modified it to run under FreeBSd
and made it actually work usefully.
Afterwards, nao@tom-yam.or.jp (HAMADA Naoki) added EISA support as well as
early support for 3C900 Etherlink XL PCI and 3C905 Fast Etherlink XL PCI.
He also split up the driver in a bus independant and bus dependant parts.

Especially the 3c59X support should be pretty stable now.

d6b9e17eb5 Improved non-statistical (GUPROF) profiling:
- use a more accurate and more efficient method of compensating for
  overheads.  The old method counted too much time against leaf
  functions.
- normally use the Pentium timestamp counter if available.
  On Pentiums, the times are now accurate to within a couple of cpu
  clock cycles per function call in the (unlikely) event that there
  are no cache misses in or caused by the profiling code.
- optionally use an arbitrary Pentium event counter if available.
- optionally regress to using the i8254 counter.
- scaled the i8254 counter by a factor of 128.  Now the i8254 counters
  overflow slightly faster than the TSC counters for a 150MHz Pentium :-)
  (after about 16 seconds).  This is to avoid fractional overheads.

files.i386:
permon.c temporarily has to be classified as a profiling-routine
because a couple of functions in it may be called from profiling code.

options.i386:
- I586_CTR_GUPROF is currently unused (oops).
- I586_PMC_GUPROF should be something like 0x70000 to enable (but not
  use unless prof_machdep.c is changed) support for Pentium event
  counters.  7 is a control mode and the counter number 0 is somewhere
  in the 0000 bits (see perfmon.h for the encoding).

profile.h:
- added declarations.
- cleaned up separation of user mode declarations.

prof_machdep.c:
Mostly clock-select changes.  The default clock can be changed by
editing kmem.  There should be a sysctl for this.

subr_prof.c:
- added copyright.
- calibrate overheads for the new method.
- documented new method.
- fixed races and and machine dependencies in start/stop code.

mcount.c:
Use the new overhead compensation method.

gmon.h:
- changed GPROF4 counter type from unsigned to int.  Oops, this should
  be machine-dependent and/or int32_t.
- reorganized overhead counters.

d805b866fa This driver supports the SDL Communications RISCom/N2 ISA cards that is
based on the HD64570 chip. Both the 1 and 2 port cards is supported.

Line speeds of up to 2Mbps is possible. At this speed about 95% of the
bandwidth is usable with 486DX processors.

The standard FreeBSD sppp code is used for the link level layer. The
default protocol used is PPP. The Cisco HDLC protocol can be used by
adding "link2" to the ifconfig line in /etc/sysconfig or where ever
ifconfig is run.

At the moment only the X.21 interface is tested. The others may need
tweaks to the clock selection code.

there is also a kernel-size interface which might be used to aid

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.

9d2baf5cdf Update the Connectix QuickCam driver to match my current work.
- split driver into FreeBSD specific and camera specific portions
  (qcamio.c can run in user mode, with a Linux "driver top" etc,
   and qcam.c should be trivial to port to NetBSD and BSDI.)
- support for 4bppand bidirectional transfers working better
- start of interleaved data-transfers byte-stream decodes (some of this
  stuff has been pulled out for the moment to make it easier to debug)

At this point, anyone who wants to port it to other platforms should feel
free to do so.  Please feed changes directly back to me so that I can produce
a unified distribution.

912e603778 Implemented non-statistical kernel profiling. This is based on
looking at a high resolution clock for each of the following events:
function call, function return, interrupt entry, interrupt exit,
and interesting branches.  The differences between the times of
these events are added at appropriate places in a ordinary histogram
(as if very fast statistical profiling sampled the pc at those
places) so that ordinary gprof can be used to analyze the times.

gmon.h:
Histogram counters need to be 4 bytes for microsecond resolutions.
They will need to be larger for the 586 clock.
The comments were vax-centric and wrong even on vaxes.  Does anyone
disagree?

gprof4.c:
The standard gprof should support counters of all integral sizes
and the size of the counter should be in the gmon header.  This
hack will do until then.  (Use gprof4 -u to examine the results
of non-statistical profiling.)

config/*:
Non-statistical profiling is configured with `config -pp'.
`config -p' still gives ordinary profiling.

kgmon/*:
Non-statistical profiling is enabled with `kgmon -B'.  `kgmon -b'
still enables ordinary profiling (and distables non-statistical
profiling) if non-statistical profiling is configured.
