87fcda4634 Remove FAT_CURSOR, it is already non-existent during several

5ddda58b2e o Restore removed hardware cursor support and make it _default_
case, software cursor now optional case. Driver must provide
  raw things (what hardware do for us, exactly) as default case,
  all driver features must be _optional_. Modern VGAs have internal
  configuration utilities to set cursor shape/blinking which stored
  into cards ROM, and syscons nuke out such features completely
  by forcing software cursor. Moreover, software cursor is hard
  to distinguish on standouted (or near standouted) fields and
  tends to disappearse from the screen.
  Set "flags 0x4" to enable software cursor now.

o Cleanup screen savers.

o Don't draw cursor if saver or blinker is active.

o Duplicated code moved to functons.

o Add more checks for blinker in progress, character lost otherwise
  when blinker restore old contents.

o Reduce blinking counter to 3, too slow in old variant.

o Fix timeout code in scrn_timer(), old variant can reenter iself,
  if action takes too long time.

o Disable visual bell for scroll lock mode, saved screen
  becomes overwritted otherwise.

d3a10e2cad Comment out pmap_prefault for the time being (perhaps until after 2.1).
The object_init_pt routine is still enabled and used, however, and this
is where most of the 'pre-faulting' performance improvement comes from.

b5d89ca8ad Load the kernel symbol table in the boot loader and not at compile time.
(Boot with the -D flag if you want symbols.)

Make it easier to extend `struct bootinfo' without losing either forwards
or backwards compatibility.

ddb_aout.c:
Get the symbol table from wherever the loader put it.
Nuke db_symtab[SYMTAB_SPACE].

boot.c:
Enable loading of symbols.  Align them on a page boundary.  Add printfs
about the symbol table sizes.
Pass the memory sizes to the kernel.
Fix initialization of `unit' (it got moved out of the loop).
Fix adding the bss size (it got moved inside an ifdef).
Initialize serial port when RB_SERIAL is toggled on.
Fix comments.
Clean up formatting of recently added code.

io.c:
Clean up formatting of recently added code.

netboot/main.c, machdep.c, wd.c:
Change names of bootinfo fields.

LINT:
Nuke SYMTAB_SPACE.
Fix comment about DODUMP.

Makefile.i386:
Nuke use of dbsym.
Exclude gcc symbols from kernel unless compiling with -g.
Remove unused macro.
Fix comments and formatting.

genassym.c:
Generate defines for some new bootinfo fields.  Change names of old ones.

locore.s:
Copy only the valid part of the `struct bootinfo' passed by the loader.
Reserve space for symbol table, if any.

machdep.c:
Check the memory sizes passed by the loader, if any.  Don't use them yet.

bootinfo.h:
Add a size field so that we can resolve some mismatches between the loader
bootinfo and the kernel boot info.  The version number is not so good for
this because of historical botches and because it's harder to maintain.
Add memory size and symbol table fields.  Change the names of everything.

Hacks to save a few bytes:

asm.S, boot.c, boot2.S:
Replace `ouraddr' by `(BOOTSEG << 4)'.

boot.c:
Don't statically initialize `loadflags' to 0.  Disable the "REDUNDANT"
code that skips the BIOS variables.  Eliminate `total'.  Combine some
more printfs.

boot.h, disk.c, io.c, table.c:
Move all statically initialzed data to table.c.

io.c:
Don't put the A20 gate bits in a variable.

fb1322e408 Decrease MCLBYTES from 4k back to 2k. It isn't likely that we'll be doing
page flipping anytime soon and 4k just wastes memory. Performance via the
looback interface will decrease slightly by this change. Idealy, we need
buffers that can have variable sizes, but this requires a rewrite of far
too much code at the moment.

Obtained from:
bios boot block changed to allow booting from both the attached graphics
display and from a serial port. (A specially compiled serial boot block
is no longer necessary.) The boot block should detect the presence or
absence of a keyboard: if there is no keyboard, COM1 is turned into the
console. This simulates the behavior of the Sun boot PROMs. Unplug your
keyboard, attach a terminal to COM1 and you should be ready to go. :)

Obtained from:
sio.c and sioreg.c changed to allow autodetecting the RB_SERIAL flag
passed by the boot blocks so that the kernel can switch to 'serial
console' mode automagically. 'options COMCONSOLE' can still be specified
to force the kernel to always use the serial port as a console.
CONUNIT and CONADDR can also be specified in the kernel config file
if the user wants to shift the console to a different port.

2d2fb1bf6b The %eflags checking introduced in the previous commit was too zealous.
sigreturn() sometimes failed for ordinary returns from signal handlers.
Failures of ordinary returns "can't happen" and are badly handled.
"Temporary" fix: allow users to corrupt PSL_RF.  This is fairly
harmless.  A correct fix would involve saving the old %eflags (and
perhaps the old segment registers) where the user can't get at them.

b60e6e6e9f Some fixes to device configuration, now that I've had a chance to do it
properly from the beginning:

	1) The `kern_devconf' struct should be a part of the driver's
	   `softc' structure (now it is).
	2) The `description' should say what the device actually is,
	   rather than just giving a model number (now it does).
	3) The device should be registered even if the probe fails, so
	   that it can be reconfigured later.
	4) For netifs, the device state should follow the IFF_UP flag.

Other network interfaces should follow this example.  (Please?)  Eventually
there should be a rundown routine doing the equivalent of setting IFF_UP
off, and perhaps more if warranted.

20415301cd Fix security holes in sigreturn(), ptrace() and procfs. sigreturn()
attempted to check for insecure and fatal eflags and segment
selectors, but missed many cases and got the IOPL check back to
front.  The other syscalls didn't check at all.

sys_process.c, machdep.c:
Only allow PT_WRITE_U to write to the registers (ordinary and FP).

psl.h, locore.s, machdep.c:
Eliminate PSL_MBZ, PSL_MBO and PSL_USERCLR.  We are not supposed
to assume anything about the reserved bits.  Use PSL_USERCHANGE
and PSL_KERNEL instead.  Rename PSL_USERSET to PSL_USER.

exception.s:
Define a private label for use by doreti when returning to user
mode fails.

machdep.c:
In syscalls, allow changing only the eflags that can be changed on
486's in user mode (no longer attempt to allow benign IOPL changes;
allow changing the nasty PSL_NT; don't allow changing the i586
bits).

Don't attempt to check all the cases involving invalid selectors
and %eip's.  Just check for privilege violations and let the invalid
things cause a trap.

procfs_machdep.c:
Call the ptrace register functions to do all the work for reading
and writing ordinary registers and for single stepping.

trap.c:
Ignore traps caused by PSL_NT being set.  Previously, users could
cause a fatal trap in user mode by setting PSL_NT and executing an
iret, and a fatal trap in kernel mode by setting PSL_NT and making
a syscall.  PSL_NT was cleared too late and not in enough modes to
fix the problem.

Make all traps in user mode (except T_NMI) nonfatal.

Recover from traps caused by attempting to load invalid user
registers in doreti by restarting the traps so that they appear to
occur in user mode.
---

Fix bogons that I noticed while fixing the above:

psl.h:
Fix some comments.

Uniformize idempotency ifdef.

exception.s, machdep.c:
Remove rsvd[0-14].  rsvd0 hasn't been reserved since the 486 came
out.  Replace rsvd0 by `align'.  rsvd[0-11] used wrong (magic
non-unique) trap numbers.  Replace rsvd[1-14] by rsvd.

locore.s:
Enable alignment check flag on 486's and 586's.

machdep.c:
Use a better type for kstack[].

Use TFREGP() to find the registers.

Reformat ptrace functions from SEF to something closer to KNF.

procfs_machdep.c:
The wrong pointer to the registers got fixed as a side effect.

Implement reading and writing of FP registers.

/proc/*/*regs now work (only) for processes that are in memory.

Clean up comments.

trap.c, trap.h:
Remove unused trap types.

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.

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

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:

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.

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.

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.

kernel happens to have an "options COMCONSOLE".  Most of the code is
actually shared with "biosboot", and make will not (and should not)

d33095d2b2 The physical memory allocated for input DMA must be contiguous. The driver
worked in the past only because of good fortune. Anyway, use the contig alloc
routine I wrote awhile ago (vm_page_alloc_contig) for the sound code to do
this allocation. Also, specify read+write on the permissions to pmap_enter().
Specifying just read can have unexpected consquences.

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>.

>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.

1ca6f46d56 Reverse the meaning of previous change.
Now floppy tape support is *disabled* unless you specifically

though it may seem counter-intuitive.  We can always change it back, later.

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.
