3e3e4375c8 Shoot the LKM support in the old wd/wdc/atapi driver set in the head and
perform a cleanup/unifdef sweep over it to tidy things up.  The atapi
code is permanently attached to the wd driver and is always probed.

I will add an extra option bit in the flags to disable an atapi probe on
either the master or slave if needed, if people want this.

Remember, this driver is destined to die some time.  It's possible that
it will loose all atapi support down the track and only be used for
dumb non-ATA disks and all ata/atapi devices will be handled by the new
ata system.

ATAPI, ATAPI_STATIC and CMD640 are no longer options, all are implicit.

e9deda23ae Keyboard driver update in preparation for the USB keyboard driver.
- Refined internal interface in keyboard drivers so that:
  1. the side effect of device probe is kept minimal,
  2. polling mode function is added,
  3. and new ioctl and configuration options are added (see below).

- Added new ioctl: KDSETREPEAT
  Set keyboard typematic rate.  There has existed an ioctl command,
  KDSETRAD, for the same purpose.  However, KDSETRAD is dependent on
  the AT keyboard.  KDSETREPEAT provides more generic interface.
  KDSETRAD will still be supported in the atkbd driver.

- Added new configuration options:
  ATKBD_DFLT_KEYMAP
  Specify a keymap to be used as the default, built-in keymap.
  (There has been undocumented options, DKKEYMAP, UKKEYMAP, GRKEYMAP,
  SWKEYMAP, RUKEYMAP, ESKEYMAP, and ISKEYMAP to set the default keymap.
  These options are now gone for good.  The new option is more general.)

  KBD_DISABLE_KEYMAP_LOADING
  Don't allow the user to change the keymap.

2ad872c579 The first stage of console driver reorganization: activate new
keyboard and video card drivers.

Because of the changes, you are required to update your kernel
configuration file now!

The files in sys/dev/syscons are still i386-specific (but less so than
before), and won't compile for alpha and PC98 yet.

syscons still directly accesses the video card registers here and
there; this will be rectified in the later stages.

925f368193 From the submitter:
CPU_WT_ALLOC does not work correctly for K6-2s of model 8+ and
probably K6-3s (when they appear on the market soon). In addition,
print_AMD_info() incorrectly printfs write allocation's size. I've
fixed them, so they now Do The Right Thing, and added a
"NO_MEMORY_HOLE" option to easily allow 15-16mb range handling for us
K6 and K6-2 users.

19c749625f Initial entry of ISDN4BSD into the FreeBSD tree.
ISDN4BSD is the work of our brand-new comitter: Hellmuth Michaelis,
who has done a tremendous amount of work to bring us this far.

There are still some outstanding issues and files to bring into
the tree, and for now it will be needed to pick up all the extra
docs from the isdn4bsd release.

It is probably also a very good idea to subscribe to the isdn@freebsd.org
mailing list before you try this out.

These files correspond to release "beta Version 0.70.00 / December
1998" from Hellmuth.

69acd21dfd Add support for the YE-Data external PCMCIA floppy driver. This
floppy is used on the toshiba Libretto line of subnotebook computers.
It differs from a normal floppy in that you must use PIO rather than
DMA to transfer the data.

To enable this, you must add options "FDC_YE" to your kernel.  I don't
have a machine that has a floppy and a pcmcia slot to test to make
sure that this doesn't impact normal floppy units, so I've left this as
an option.

I have ported this to -current and made an attempt to ensure that the
indentation conforms to style(9), aka the bruce filter.

Kazu writes:

The VESA support code requires vm86 support. Make sure your kernel
configuration file has the following line.
        options "VM86"
If you want to statically link the VESA support code to the kernel,
add the following option to the kernel configuration file.
        options "VESA"

The vidcontrol command now accepts the following video mode names:
VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600

The VESA_800x600 mode is a raster display mode. The 80x25 text will
be displayed on the 800x600 screen. Useful for some laptop computers.

vidcontrol accepts the new `-i <info>' option, where <info> must be
either `adapter' or `mode'.  When the `-i adapter' option is given,
vidcontrol will print basic information (not much) on the video
adapter. When the `-i mode' option is specified, vidcontrol will
list video modes which are actually supported by the video adapter.

b3196e4b9f Preliminary support for per-cpu data pages.
This eliminates a lot of #ifdef SMP type code.  Things like _curproc reside
in a data page that is unique on each cpu, eliminating the expensive macros
like:    #define curproc (SMPcurproc[cpunumber()])

There are some unresolved bootstrap and address space sharing issues at
present, but Steve is waiting on this for other work.  There is still some
strictly temporary code present that isn't exactly pretty.

This is part of a larger change that has run into some bumps, this part is
standalone so it should be safe.  The temporary code goes away when the
full idle cpu support is finished.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

11b5ea7239 Since there have been so many reports of the Memory Mapped I/O to the
aic7xxx cards failing on certain motherboards, reverse the logic used to
control this feature.  AHC_FORCE_PIO is replaced with AHC_ALLOW_MEMIO.
GENERIC no longer needs to specify the AHC_FORCE_PIO option since this is
the default.

1fe048505d Replaced I586_OPTIMIZED_BCOPY and I586_OPTIMIZED_BZERO with boot-time
negative-logic flags (flags 0x01 and 0x02 for npx0, defaulting to unset = on).
This changes the default from off to on.  The options have been in current
for several months with no problems reported.

Added a boot-time negative-logic flag for the old I5886_FAST_BCOPY option
which went away too soon (flag 0x04 for npx0, defaulting to unset = on).

Added a boot-time way to set the memory size (iosiz in config, iosize in
userconfig for npx0).

LINT:
Removed old options.  Documented npx0's flags and iosiz.

options.i386:
Removed old options.

identcpu.c:
Don't set the function pointers here.  Setting them has to be delayed
until after userconfig has had a chance to disable them and until after
a good npx0 has been detected.

machdep.c:
Use npx0's iosize instead of MAXMEM if it is nonzero.

support.s:
Added vectors and glue code for copyin() and copyout().
Fixed ifdefs for i586_bzero().
Added ifdefs for i586_bcopy().

npx.c:
Set the function pointers here.
Clear hw_float when an npx exists but is too broken to use.
Restored style from a year or three ago in npxattach().

33c58c9f8f Remove option I586_FAST_BCOPY. The code will be included by default
if I586_CPU is defined.  Note there is a runtime check so the code
won't be run for non-Pentium CPUs anyway.

2.2 candidate, this code has been tested for almost half year in -current.

1affda38c1 Add two new aic7xxx driver options:
AHC_FORCE_PIO - This forces the driver to use PIO even on systems that
	say they have memory mapped the controller's registers.  This
	seems to fix Ken Lam's problems.  I've also placed this option
	in the GENERIC kernel file so that we are guaranteed to install
	even on these flakey machines.

AHC_SHARE_SCBS - This option attempts to share the external SCB SRAM on
	the 398X controllers allowing a totoll of 255 non-paged SCBs.
	This doesn't work quite yet, so this option is mostly here to
	help 398X owners to experiment and give me feedback until this
	works properly.

dcb21864dc Remove SC_KBD_PROBE_WORKS option and replace it with a simple run-time flag
bit (0x0008) in the sc driver configuration line.  This way it's easy to
boink a generic kernel.

Also, document and place in an opt_ file the #define's for overriding which
serial port is the system console.

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.

d50a30076c Multiple changes stacked as one commit since they all depend on one another.
First, change sysinstall and the Makefile rules to not build the kernel
nlist directly into sysinstall now.  Instead, spit it out as an ascii
file in /stand and parse it from sysinstall later.  This solves the chicken-n-
egg problem of building sysinstall into the fsimage before BOOTMFS is built
and can have its symbols extracted.  Now we generate the symbol file in
release.8.

Second, add Poul-Henning's USERCONFIG_BOOT changes.  These have two
effects:

	1. Userconfig is always entered, rather than only after a -c
	   (don't scream yet, it's not as bad as it sounds).

	2. Userconfig reads a message string which can optionally be
	   written just past the boot blocks.  This string "preloads"
	   the userconfig input buffer and is parsed as user input.
	   If the first command is not "USERCONFIG", userconfig will
	   treat this as an implied "quit" (which is why you don't need
	   to scream - you never even know you went through userconfig
	   and back out again if you don't specifically ask for it),
	   otherwise it will read and execute the following commands
	   until a "quit" is seen or the end is reached, in which case
	   the normal userconfig command prompt will then be presented.

  How to create your own startup sequences, using any boot.flp image
from the next snap forward (not yet, but soon):

	% dd of=/dev/rfd0 seek=1 bs=512 count=1 conv=sync <<WAKKA_WAKKA_DOO
USERCONFIG
irq ed0 10
iomem ed0 0xcc000
disable ed1
quit
WAKKA_WAKKA_DOO


Third, add an intro screen to UserConfig so that users aren't just thrown
into this strange screen if userconfig is auto-launched.  The default
boot.flp startup sequence is now, in fact, this:

	USERCONFIG
	intro
	visual

(Since visual never returns, we don't need a following "quit").

dad0de774e Removed bogus LARGMEM code and option. The code paniced when
biosextmem > 65536, but biosextmem is a 16-bit quantity so it is
guaranteed to be < 65536.  Related cruft for biosbasemem was
mostly cleaned up in rev.1.26.

683cbdf4af Fixed spelling of new SC_KBD_PROBE_WORKS option in options.i386.
It worked because it is spelled correctly in LINT.

Added old obscure syscons options MAXCONS, SLOW_VGA and XT_KEYBOARD.
This file should be sorted both alphabetically and on the module
name by using a consistent prefix for each module, but there is no
consistency in the old options.  E.g., MAXCONS is spelled PCVT_NSCREENS
for pcvt.

d69e850255 Add support for Pentium and Pentium Pro performance counters.
(This code is as yet untested; to come after man page is written.)
This also adds inlines to cpufunc.h for the RDTSC, RDMSR, WRMSR, and RDPMC
instructions.  The user-mode interface is via a subdevice of mem.c;
there is also a kernel-size interface which might be used to aid
profiling.

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.

d92566062f Choose a different name to hold the option definition.. The original one
