290dd077ef Here is a minor patch for FreeBSD 2.0R to allow it to recognize
2.88MB floppy drives.  All it does is set the type to 1.44MB if
it finds the 2.88MB drive.

cronix.h is <machine/cronix.h>, not "cronyx.h" (ambiguous) or
<sys/cronyx.h> (nonexistent; caused compile to fail).

cxreg.h is <i386/isa/cxreg.h>, not "cxreg.h".

<i386/isa/cpufunc.h> shouldn't be included directly; it is always
included by <sys/systm.h>.

<kernel.h> is <sys/kernel.h>.

<bpfilter.h> is "bpfilter.h".  It really is in the current directory.

>Description:

       If a process attempts to open a floppy tape device when the
device has been configured in the kernel, but did not probe and attach
on bootup, then a panic will occur.

[Review:  The current ft situation is a crock, and this only bandaids
 an earlier wound inflicted by making the attach conditional.  This urgently
 requires a review]

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.

a7d72265c4 The values for setrlimit in the data size and stack size case are
used as an address value. Then all comparisons should be done unsigned
and not signed. Fix it with a typecast of u_quad_t.
Error can be demonstrated with the current bash in port, do a
ulimit -s unlimited and the machine hangs. bash delivers through
an internal error a large negative value for the stacksize, the
comparison saw this smaller than MAXSSIZ and then tried to expand
the stack to this size.

d439025208 Temporary kludge: treat \r same as \n in input, so working on a
comconsole will behave as expected.  The true problem should be fixed
instead, Bruce' comment for this:

>Anyway, i found the reason for my problems: somehow, ICRNL isn't in
>effect at `userconfig' time (but only for comconsole?), hence only

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.

eadf9e27cd These changes fix a couple of lingering VM problems:
1.	The pageout daemon used to block under certain
	circumstances, and we needed to add new functionality
	that would cause the pageout daemon to block more often.
	Now, the pageout daemon mostly just gets rid of pages
	and kills processes when the system is out of swap.
	The swapping, rss limiting and object cache trimming
	have been folded into a new daemon called "vmdaemon".
	This new daemon does things that need to be done for
	the VM system, but can block.  For example, if the
	vmdaemon blocks for memory, the pageout daemon
	can take care of it.  If the pageout daemon had
	blocked for memory, it was difficult to handle
	the situation correctly (and in some cases, was
	impossible).

2.	The collapse problem has now been entirely fixed.
	It now appears to be impossible to accumulate unnecessary
	vm objects.  The object collapsing now occurs when ref counts
	drop to one (where it is more likely to be more simple anyway
	because less pages would be out on disk.)  The original
	fixes were incomplete in that pathological circumstances
	could still be contrived to cause uncontrolled growth
	of swap.  Also, the old code still, under steady state
	conditions, used more swap space than necessary.  When
	using the new code, users will generally notice a
	significant decrease in swap space usage, and theoretically,
	the system should be leaving fewer unused pages around
	competing for memory.

9b1096e759 From: wpaul@ctr.columbia.edu (Bill Paul)
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.

0ef8c3017a John Aycock's aic7770 sequencer code and assembler. There is currently
a discussion going on about removing this code from the burden of the
GPL, but it won't happen before Beta, and this code should be tested
before release.

Supports 27/2842 class adaptec cards and is almost capable of supporting
aic7870 based adapters (294X series cards).  It does not support Wide
controllers or the second channel on Twin boards although I have work in
progress on getting both channels and running.

I have also added a few performance improvements to this version that give
us approximately a 25% boost over the original driver.  These patches have
been submitted to the author.

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)

471e5fa096 John Dyson's patches (and a few from me too) to LFS to use a different
buffering scheme and make it more in tune with FreeBSD's vfs_bio
implementation.  The filesystem seems fairly stable, but I wouldn't recommend
it to anyone not willing to experience problems.  This is very green code and
has the limitation that YOU CAN ONLY HAVE ONE LFS PARTITION MOUNTED AT A TIME.

What LFS is good for:

	Non fsynced writes	FASTER THAN FFS
	Large deletions		Increadibly fast

Reads are a little bit slower than FFS right now, but that is a factor of
how under optimized this code is.  LFS should in theory perform at least as
well as FFS under fsync (iozone) type loads, and this is what I'm currently
working on.

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.

sometimes leak across exits and clobber another process.  I can't see

I couldn't find a better way to avoid compiler warnings about
redundant and/or inconsistent declaration of ffs().  I'd like to
be able to declare prototypes in general headers without committing
to implementing them as `static inline' or `extern', but there
seems to be no way to do this with gcc-2.6.1.  E.g.,

	int foo(void);
	static __inline int foo(void) { return 1; }

causes a warning about the linkage mismatch, while the opposite
order causes a warning about the redundant declaration.

412ac969ed Add Matt Thomas' le0 DEPCA driver to the GENERIC kernel. This works
but I can't test to see if it walks on other ethernet drivers.  Can the
install folks add this driver to the install script?

ef53d2f8b6 Nuked ed2 - it was added for the common 16bit card case where the
irq is 10. This is auto-sensed/configured now in the 'ed' driver.

fed69e2fd2 In cases where it is possible, use the card's configured irq rather than
the one compiled into the kernel. Left in some commented-out shared memory
performance test code.

501cc59d80 I *almost* had it right. Skip over the rest of the command if it's
abbreviated.

95ea0c1390 Make the command set actually work the way I'd intended - you can abbrevate
commands now, as long as whatever you abbreviate them to remains unique.

b5cd0f92f4 mem's 2nd arg was incorrectly defined as an integer, not address parameter.
I found this out the hard way when I went to do:

	mem ed0 0xe8000

And found out that I had to enter the second parameter in decimal.. :-)

this to be coupled with the adapter specification in the config file,
so that you can say which adapters need it ?

bc8cb7d0b4 Avoid a division by zero if the actual sector size isn't known during the
device announcement; assume a sector size of 512 instead (likely to be
right at all).
This case happens when booting with a removable disk device attached
(e.g. an MOD), but no medium inserted.

98020fdd6c Added a kernel variable, "dodump" defaulting to zero, which disables dumps.
Somebody should make a mib variable for it.
Just now it is pointless to dump the kernel, since we have nothing which
can read the dump.
Furthermore is should never be the default to dump.
	options	DODUMP
will enable dumps.
