9bf308efab Eliminate T_KDBTRAP, which will soon go away. It was only used for an
unreachable case label in kdb_trap().

Use the correct case labels in kdb_trap() so that normal ddb entry doesn't
print a message.

Change all printf's to db_printf's.  Now you can put a breakpoint at printf,
and ddb entry messages don't spam the syslog output.

Cosmetic:

Use ISPL() instead of magic numbers.

Don't compile the unused function kdb_kbd_trap().

Improve some asms.

Print the arg to Debugger().

dac0f2dbc1 Argl!, finally found this bummer. The code testing for a write-
protected drive at open() time has been *totally bogus*!  The guy who
submitted it didn't understand all the implications of calling
set_motor(), and the `who' who included the patch into the tree did it
blindly...  Pleeeeze, don't commit code to this driver unless you are
really going to understand what it does!  This one caused me to pull
out even more hears, and those who know me do know that i ain't got
too many o'them. :-)

dc16046f96 Finally implement support for the `lsdev' program. The controller is
now marked busy as long as it's being in non-reset state, and the
drives are busy as long as at least one instance is open.

Also reformat everything to fit into 80 columns again.

Changed my mind wrt. error reporting for a write-protected drive and
an open() with write intent; ENXIO has been too weird, now return EIO.
Some portions of the code need to be rewritten to use tprintf()
instead of simple printf()'s, so the messages will also appear on the
session terminal, however.

0d94caffca These changes embody the support of the fully coherent merged VM buffer cache,
much higher filesystem I/O performance, and much better paging performance. It
represents the culmination of over 6 months of R&D.

The majority of the merged VM/cache work is by John Dyson.

The following highlights the most significant changes. Additionally, there are
(mostly minor) changes to the various filesystem modules (nfs, msdosfs, etc) to
support the new VM/buffer scheme.

vfs_bio.c:
Significant rewrite of most of vfs_bio to support the merged VM buffer cache
scheme.  The scheme is almost fully compatible with the old filesystem
interface.  Significant improvement in the number of opportunities for write
clustering.

vfs_cluster.c, vfs_subr.c
Upgrade and performance enhancements in vfs layer code to support merged
VM/buffer cache.  Fixup of vfs_cluster to eliminate the bogus pagemove stuff.

vm_object.c:
Yet more improvements in the collapse code.  Elimination of some windows that
can cause list corruption.

vm_pageout.c:
Fixed it, it really works better now.  Somehow in 2.0, some "enhancements"
broke the code.  This code has been reworked from the ground-up.

vm_fault.c, vm_page.c, pmap.c, vm_object.c
Support for small-block filesystems with merged VM/buffer cache scheme.

pmap.c vm_map.c
Dynamic kernel VM size, now we dont have to pre-allocate excessive numbers of
kernel PTs.

vm_glue.c
Much simpler and more effective swapping code.  No more gratuitous swapping.

proc.h
Fixed the problem that the p_lock flag was not being cleared on a fork.

swap_pager.c, vnode_pager.c
Removal of old vfs_bio cruft to support the past pseudo-coherency.  Now the
code doesn't need it anymore.

machdep.c
Changes to better support the parameter values for the merged VM/buffer cache
scheme.

machdep.c, kern_exec.c, vm_glue.c
Implemented a seperate submap for temporary exec string space and another one
to contain process upages. This eliminates all map fragmentation problems
that previously existed.

ffs_inode.c, ufs_inode.c, ufs_readwrite.c
Changes for merged VM/buffer cache.  Add "bypass" support for sneaking in on
busy buffers.

f73f117cf0 Don't allow negative console numbers for the VT_WAITACTIVE ioctl. Use the
correct console number for the VT_WAITACTIVE ioctl.  Invalid console numbers
caused waiting on an invalid pointer.

Use bcopyw() instead of move_up() and move_down().  bcopyw() handles
overlapped copies and should be faster.  Actually use bcopy().  bcopy()
is slightly faster if video memory is 16-bit and about twice as fast if
it is 32-bit.  bcopy() is said to fail on someGA's, but syscons already
depends on it working for other accesses to video memory.

37e52b59cc Use sufficient parentheses in macros.
Remove bogus input operands for fnsave(), fnstcw() and fnstsw().

Change all fwait's to fnop's.  This might help avoid hardware bugs.
Wait after fninit with an fnop.  This should be safer now.

Fix some spelling and formatting errors.

Use natural sizes for control and status words (u_short, promotes to int).

Don't clobber the SWI_CLOCK_MASK bits in npx0_imask when using IRQ13.

Set the devconf state correctly (always busy, if configured).  Improve
code for npx_registerdev() a little (gcc can't keep id->id_unit in a
register for some reason).  Don't register a nonexistent npx device.

Print a useful message in npxattach() again (delete references to errors
and not the whole message).  Don't print "387 emulator" if there is no
emulator in the kernel.

Use %p for pointers in error messages.

Don't clobber the FPU state when there is an FPU exception.  Just clear
the exception flags (after saving the flags as before).  This allows
debuggers and SIGFPE handlers to look at the full exception state.
SIGFPE handlers should normally return via longjmp(), which restores a
good FPU state (as before).  Returning from a SIGFPE handler may leave
the FPU in the wrong state (as before).

Clear the busy latch _after_ clearing the exception flags so that there
is less chance of getting a bogus h/w interrupt for a control operation.

Clear the saved exception status word when the next FPU instruction is
excuted so that it doesn't stick around until the next exception.

Clear the busy latch after fnsave() in npxsave() in case it was set when
npxsave() was called.

dd4a485085 From Bill Paul:
- /sys/i386/i386/swapgeneric.c is just plain broke. But fear not, for I
  have unbroken it. One thing that swapgeneric.c does is walk through the
  list of configured devices searching for a boot device. The only easy
  way to accomplish this in 2.0 is to use Garret Wollman's kern_devconf
  stuff. *BUT*, the head of the kern_devconf linked list (dc_list) is declared
  static in /sys/kern/kern_devconf.c. This means that swapgeneric.c can't
  see it at link time. I had to remove the 'static' keyword to get around
  this little problem. I hope this doesn't break anything anywhere.

  *Furthermore,* there's a small matter of making the call to setconf()
  in swapgeneric.c disappear when 'config kernel swap generic' isn't used.
  You could change /sbin/config to create a dummy setconf() function in
  swapkernel.c, but that seems messy somehow. (It's also someting of an
  'it isn't broken, why are you fixing it' situation.) My solution was to
  do what the NetBSD people did and put an #ifdef GENERIC around the call
  to setconf(). If your kernel is called GENERIC or you define 'options
  GENERIC,' then you can use 'config kernel swap generic' and it'll work.

  That aside, the upshot is that: a) swapgeneric.c actually works, and
  and b) the -a boot flag now works as well. If you boot with -a, as in
  "Boot: wd(0,a)/kernel -a" you will be presented with a 'root device?'
  prompt after the autoconfig phase, at which point you can specify what
  device you want mounted as root. Regrettably, you can't specify an NFS
  filesystem. Yet. Three files are affected: /sys/i386/i386/swapgeneric.c,
  /sys/i386/i386/autoconf.c and /sys/kern/kern_devconf.c.

63c5d14d1b Miscellaneous changes from Bill Paul:
- /sys/i386/isa/if_ed.c doesn't quite know how to deal with SMC EtherEZ
  ethernet cards. The EtherEZ looks just like the Elite Ultra, except it
  has only 8K of shared memory. The only way to have it properly detected
  is to zero and test a few bytes of memory just about the first 8K region.
  If it clears properly, it's an Elite Ultra, otherwise it's an EtherEZ.

  I've also got an EtherEZ patch for netboot (Makefile, ether.c and ether.h).

- /sys/i386/isa/syscons.c wraps at the next to the last column rather than
  the last column, like it should. You don't really notice this unless you
  use certain programs that write all the way out to, say, the 80th column,
  like VMSmail. Along with a one-line fix for this are some changes to
  implement a non-blinking cursor. Put 'options "NOBLINK_CURSOR"' in your
  config file and give it a try. :)

10bfdf2bae From: "Serge V.Vakulenko" <vak@gw.cronyx.msk.su>
This is new version of Seagate ST01/02, Future Domain TMC-885, TMC-950
SCSI driver for FreeBSD.  I started from the 2.0R version and mostly
rewrote it.  New features are:

1) New probe algorithm.  Old driver read the BIOS region of the adapter
   memory and find the copyright string.  The problem was in the BIOS itself:
   it conflicted with IDE disks.  The solution was to unplug it and
   make the probe algorithm to work without it.
2) Proper timeout handling in numerous places where the driver
   polls waiting for some event.
3) Assembler flagments added in critical places, mostly for data transfer
   to of from the target.  It was possible to make it faster,
   but at the price of decreasing reliability.
4) Target-dependent delays when waiting for REQ deassert event.
   Some devices seem to be slower (CD-ROMS, some tape drives),
   and some seem to be too fast (disks).  The driver tests the REQ
   deassert timeout for each target and then uses it for polling.
5) Device flags added for SCSI parity control and sense request
   priority control.
6) Generic cleanup, after which the driver became much more readable
   (at least by me:).
7) Target data parity error logging is limited to avoid log file overflow.
8) Manual page added.

e72e8750d3 Insert a hook to initialize the serial port at the beginning of
boot().  This is needed so the "serialboot" stuff can share this file,
too.

Everything is #ifdef'ed so it evaluates to nothing when actually been
built in the "biosboot" directory.

2c681fc102 This became a frequently requested item now.
The files in this directory are modified version of "biosboot".  The
only difference is in that they perform their I/O via a serial port,
so their preferrable usage is to form bootblocks for systems where the
kernel happens to have an "options COMCONSOLE".  Most of the code is
actually shared with "biosboot", and make will not (and should not)
descend into this directory by default.  It is in the responsibility
of the user to build these bootblocks instead of the original ones.

This stabilizes a couple of APM bioses quite a bit.

Later they do a

|	movw %ax,0x6(%si)

is already relocated, so adding 0xf0171ce9 to the base of it is bad news.

b39b673d37 i386/exception.s,
Keep track of interrupt nesting level.  It is normally 0
	for syscalls and traps, but is fudged to 1 for their exit
	processing in case they metamorphose into an interrupt
	handler.

i386/genassym.c;
	Remove support for the obsolete pcb_iml and pcb_cmap2.

	Add support for pcb_inl.

i386/swtch.s:
	Fudge the interrupt nesting level across context switches and in
	the idle loop so that the work for preemptive context switches
	gets counted as interrupt time, the work for voluntary context
	switches gets counted mostly as system time (the part when
	curproc == 0 gets counted as interrupt time), and only truly idle
	time gets counted as idle time.

	Remove obsolete support (commented out and otherwise) for pcb_iml.

	Load curpcb just before curproc instead of just after so that
	curpcb is always valid if curproc is.  A few more changes like
	this may fix tracing through context switches.

	Remove obsolete function swtch_to_inactive().

include/cpu.h:
	Use the new interrupt nesting level variable to implement a
	non-fake CLF_INTR() so that accounting for the interrupt state
	works.

	You can use top, iostat or (best) an up to date systat to see
	interrupt overheads.  I see the expected huge interrupt overheads
	for ISA devices (on a 486DX/33, about 55% for an IDE drive
	transferring 1250K/sec and the same for a WD8013EBT network card
	transferring 1100K/sec).  The huge interrupt overheads for serial
	devices are unfortunately normally invisible.

include/pcb.h:
	Remove the obsolete pcb_iml and pcb_cmap2.  Replace them by
	padding to preserve binary compatibility.

	Use part of the new padding for pcb_inl.

isa/icu.s:
isa/vector.s:
	Keep track of interrupt nesting level.

instead, Bruce' comment for this:

>Anyway, i found the reason for my problems: somehow, ICRNL isn't in

ICRNL doesn't apply to cngetc().  cnputc() unconditionally does the
equivalent of ONLCR; perhaps cngetc() should unconditionally do the
equivalent of ICRNL.  Ddb must be checking for CR.  Userconfig only
checks for NL.  Userconfig works with syscons because pccngetc()
does the conversion.  This is probably the wrong place to do it.

Subject: Mea culpa -- small fix for netboot fixes

In accordance with the unavoidable principle sof Murphy's Law, I discovered
that the fixes I recently contributed for the netboot code had some small
flaws in them. Two of them were just typos and had no effect on how the
program functioned. The other one was a missing line from the rootopts and
swapopts functions I created in bootmenu.c, which was supposed to initialize
the NFS sotype flag. It defaults to UDP, and you can change it to TCP with
the rootopts or swapopts commands, but then you can't change it back again.
I originally had a line at the top of each function to reinitialize this
flag, but somehow it got lost in the shuffle, probably because I don't
actually have a need for that flag yet.

68cbb04819 Many fixes from Bill Paul:
Smack the netboot program around so that it will allow the user to
  specify mount options.  [So that you can boot from a privileged port]

  Change the default boot image name in netboot to /kernel, then strip
  the leading slash when actually going out to get the NFS file handle.

  Added support for 3Com 3c503 cards. Also added another command to
  the (trans) that allows you to switch the 3Com's on-board transceiver
  on and off. (ether.c, ether.h, bootmenu.c)

  Modified the Makefile to support new compile-time options for 3c503
  cards:

  -DINCLUDE_3COM                Include support for 3c503
  -D_3COM_BASE=0x300            Define 3c503 base i/o address (if not
                                specified, 0x300 is the default)
  -D_3COM_USE_AUI               Disable the 3c503's transceiver by
                                default (without this flag the transceiver
                                is on by default)

004bedeb68 Rewrite almost everything.
Alphabetize.

Write all i/o functions in sleep so that we don't use anything from
NetBSD.

Restore the correct type of u_int for ports.  This saves a whole cycle
per i/o on 486's.

Change `inline' back to __inline to avoid compiler warnings with
-Wreally-all.

Don't implement bdb() unless BDE_DEBUGGER is defined.  Declare bdb_exists
outside the function to avoid hundreds of compiler warnings.

Let the compiler pick the register in asms if possible.

Implement ffs() using inline asm().  gcc provides a slightly different
one.  It was broken in gcc-2.4.5 but works now.  Declaring a correct
version inline ensures getting a correct version.  FreeBSD-1.1.5 has
an slow inline version but FreeBSD-2.0 has a library version (which
probably never gets used).

Do inb() and outb() without using %edx for constant ports below 0x100.

Remove casts to the same type in queue functions.

Declare prototypes for everything implemented i386/*.s and also for
everything that is normally implemented as an inline here (I don't
like the current complete dependency on gcc).  Ifdef out the prototypes
that are declared elsewhere.  THere should be a separate header to
declare things implemented in i386/*.s, but then it would be harder
to override declarations with inlines.

with the current default exception (un)mask.  There should be no such

gets saved so that it can be checked and this may have the side effect
of fixing a bug that was reported for 1.1.5.  (npx exceptions may
sometimes leak across exits and clobber another process.  I can't see
how this can happen.)

Use int_parms for the i/o "address" since the "address" is really a number
and is represented as an int.

Add command `flags' to allow changing device flags.

Fix scrolling of device listing.  Only scrolling of the current devtab
was controlled.  Reprint the header after scrolling.

Rename commands and change strings to match their config(8) keywords:

	io -> port
	IOaddr -> port
	mem -> iomem (abbreviation is io :-()
	MemAddr -> iomem
	case changes

Don't use NULL for ASCII NUL.

Call strtoul() with base 0 for both numbers and addresses so that input
is consistent and hex and octal can be used for numbers.

Fix entry of irq number.  Check the range at no extra cost.  It wasn't
possible to enter irq -1.

Format device listing better.  Large numbers (such as 0xffffffff for the
GENERIC lpt0 port) messed up the formatting.

Show the unit number in the device listing.  Comment about the fields

Rename `timer0_prescale' to `timer0_prescaler_count' and maintain it
correctly.  Previously we lost a few 8253 cycles for every "prescaled"
clock interrupt, and the lossage grows rapidly at 16 KHz.  Now we
only lose a few cycles for every standard clock interrupt.

Rename `*_divisor' to `*_max_count'.

Do the calculation of TIMER_DIV(rate) only once instead of 3 times each
time the rate is changed.

Don't allow preposterously large interrupt rates.  Bug fixes elsewhere
should allow the system to survive rates that saturate the system, however.

Clean up declarations.

Include <machine/clock.h> to check our own declarations.

ae406484f0 Fix a bug introduced between 1.1 and 1.1.5. Loading the time was moved
outside the critical region.

Make it work with 2.0.  It wasn't designed to be called at splclock().

Make it work with prescaling.  The overflow threshold was bogus.

Make it work for any HZ.  Side effect of fixing prescaling.

Speed it up.  Allocate registers better.  Reduce multiplication and
division to multiplication and a shift.  Speed is now 5-6 usec on a
486DX/33, was about 3 usec more.

Optimize for the non-pentium case.  The pentium code got moved around
a bit and hasn't been tested.

Change #include's to 2.0 style.

things declared in machine-independent files).

c342b9faa3 Disable the direct call from hardclock() to softclock(). Support
for it is incomplete and buggy.  There is no problem unless Xintr0()
is reentered or should be reentered, but high clock interrupt
frequencies for pcaudio cause Xintr0() to be reentered (or clock
ticks to be lost when Xintr0() should have been reentered but
wasn't), and we lose little by delaying the call to softclock().

Move declarations related to the clock driver to clock.h.

Move declarations related to the npx driver to npx.h.

Clean up the remaining declarations.

c897ebc21a Change -O2 to -O
With each gcc version -O2 can cause absolutely unpredicatable things
Second stage boot still fits in allowed size

4525c93ebf We need CD9660 and MSDOS filesystems built-in if the floppy is to have
a hope of getting at these types of filesystems without dragging all
the LKM stuff in.
