Bruce Evans 71fa328eb5 Made minimal changes to make this work again (it depended on devconf).
swapgeneric.c hasn't had anything to do with swapping for some time.
It just makes the -a boot option actually work, and breaks the static
configuration of rootdev and dumpdev.  It should be reorganized to
only support -a.

Bruce Evans ab372207b2 Fixed botched tables:
- the operands for bt, bts, arpl and `enter' were reversed.
- btr was reported as bts (with the correct operand order).
- cmpxchg was misplaced.  It was misplaced differently in the
  comments.  It is misplaced differently again in the i486 manual.
  I put it where the i586 manual and gas say it is.
- fucompp was misplaced.
- the rr table for(s) some versions of fstp, fcom and fcomp was non-null.
  This caused some invalid opcodes to be reported as "" instead of as
  "<bad instruction>".
- the word and long versions of the fi* instructions were reversed.
- aaa and daa were reversed.

Fixed bugs involving unusual operand sizes:
- 32-bit registers weren't always forced for bswap or for moves to and
  from special registers.
- the operand sizes weren't reported for [l]call or [l]jmp.
- displacements weren't truncated mod 2^16 when the operand size was
  16-bit.
- too-large displacements and offsets were fetched, and too-large
  offsets were reported, when the operand size was 16-bit.
- sign extended immediate bytes were extended too far when the operand
  size was 16-bit.

Fixed bugs involving usual operand sizes:
- 8-bit source registers weren't forced for mov[sz]b[wl].
- 16-bit source registers weren't forced for mov[sz]w[wl].
- immediate bytes were sometimes reported as sign extended even for
  byte operations.  Same for immediate words in word operations.
- the immediate byte was not reported as sign extended for `push'.

Finished Pentium support:
- cpuid, cmpxchg8b and rsm were missing.

Finished i287 support:
- fneni, fndisi and fsetpm were missing.  These are harmless nops on
  later FPUs.

Improvements:
- report invalid opcodes 0xd6 and 0xf1 using .byte.  They are special
  in not causing invalid operand exceptions when executed.
- report the immediate byte for unusual aam and aad instuctions.
  Immediate bytes other than 0x0a always worked and are documented to
  work on Pentiums.

Stefan Eßer 8c39a12760 Add code to copy the LDT, if required.
This code was sent to me by Bruce Evans, and seems to fix some
possible kernel panic in case of an execution error. It did not
cause any problems on my system, but I did never observe the
problem this patch is supposed to fix, anyway.

This patch is a NOP, unless the kernel is built with "options
USER_LDT", and doesn't affect the GENERIC kernel for this reason.

Joerg Wunsch effbfcfdc6 Apparently, someone changed the gsc driver to allocate one big buffer
at device attach time, instead of allocating and freeing buffers as
necessary. But he or she forgot to remove the line that invalidated
the buffer when the device is closed. Therefore, after using the
device for the first time, the buffer was incorrectly invalidated and
that caused a page fault on the second, and subsequent uses.

John Dyson d0aea04fe0 Let the VM system know that on certain arch's that VM_PROT_READ
also implies VM_PROT_EXEC.  We support it that way for now,
since the break system call by default gives VM_PROT_ALL.  Now
we have a better chance of coalesing map entries when mixing
mmap/break type operations.  This was contributing to excessive
numbers of map entries on the modula-3 runtime system.  The
problem is still not "solved", but the situation makes more
sense.

Eventually, when we work on architectures where VM_PROT_READ
is orthogonal to VM_PROT_EXEC, we will have to visit this
issue carefully (esp. regarding security issues.)

Broke locking on named pipes in the same way as locking on non-vnodes

The fix involves negative logic.  Named pipes are now distinguished from
other types of files with vnodes, and there is additional code to handle
vnodes and named pipes in the same way only where that makes sense (not
for lseek, locking or TIOCSCTTY).

Poul-Henning Kamp 673f8923d0 PR kern/2141:
function ed_attach_NE2000_pci() in if_ed.c passes
        an uninitialized block of memory (got with malloc())
        to ed_attach. This prevents a proper initialization
        of the device descriptor and in my case causes a panic
        during the probe, while printing out device info.

Søren Schmidt 1f9d9075e4 Alot of fixes from kazu:
1. All the suggestions earlier made by Bruce: renaming some symbols,
stricter error checking, removing redundant code, etc.

2. The `psm' driver preserves the default counter resolution and
report rate, whatever they are after reset. (Based on reports and
suggestion from Nate and Rob Bolin).

3. The `psm' driver now does not check the so-called sync. bit in the
first byte of the data packet by default, so that the tapping feature
of ALPUS GlidePoint works (based on reports from Louis Mamakos). I
tested the code with ALPUS Desktop GlidePoint (M/N GP101) and found
no problem; tapping worked. It appears ALPUS produces several models
of GlidePoint. I hope the other models are OK too.

The check code can still be activated by defining the PSM_CHECKSYNC
option in the config file. (The bit checking slightly reduces, if not
completely eliminates, weird mouse behavior cased by unsynchronized
mouse data packets. It also helps us to detect if the mouse interrupt
can ever be lost. But, well, if there are devices which cannot be
supported this way...)

4. The `psm' driver does not include the protocol emulation code by
default. The code can still be compiled in if the PSM_EMULATION option
is specified in the config file. Louis Mamakos suggests the emulation
code is putting too much in the kernel, and `moused' works well.
I will think about this later and decide if the entire emulation
code should be removed.

5. And, of course, the fix in `scprobe()' from Bruce to cure the
UserConfig problem. My code in `kbdio.c' is slightly different from
his patch, but has the same effect. There still is a possibility that
`scprobe()' gets confused, if, for whatever reasons, the user holds
down a key for very long time during the boot process. But we cannot
cope with everything, can we?

probe routine.  Since the probe routine was not yet called, the port was

Justin T. Gibbs 74bb76f011 Be even more careful in how we manipulate the QOUTQCNT variable. Now we
do reset it from the QOUTCNT register inside a pause/unpause.  This now happens
once per command complete interrupt in the paging case (one interrupt can be
for multiple completed commands).  I may introduce a counter and do a lazy
update in the future, similar to what is done with the QINCNT.

Enhance the QUEUE FULL condition handling so that the number of openings will
be reduced.  This has become more important now that the driver is faster.
This code really belongs in the gerneric SCSI layer, as will be the case once
3.0 gets the code from the 'SCSI' branch.

Add some #if 0'd out trace code I've been using to help debug sequencer
problems.

Fix the SCB paging problem that I was seeing.  This was only on my 7850
controller and stems from the fact that its QINFIFO can only handle 3bit
SCB identifiers.  This means that you can only have 8 transactions open at
a time with the current paging scheme to these controllers.  The code added
to enforce this is generic in that it tests for the number of relevent bits
that the QINFIFO can store and adjusts the max accordingly.  It may be possible
to come up with a scheme that allows for more than 8 commands at a time, but
I don't know that it is worth the effort simply to fix a low end card.  The
aic7880 still can do 255.

This problem may be related to what Andrey was seeing since I don't have n
aic7770 rev E chip here to test on, but as soon as someone probes one of these
cards with this new code, the dmesg output will tell the whole story.

Justin T. Gibbs 30136d82b2 Clean up the memory mapped/Programmed I/O stuff so that the driver completely
uses one or the other.  This required some changes to the ahc_reset()
function, and how early the probes had to allocate their softc.

Turn the AHC_IN/OUT* macros into inline functions and lowercase their names
to indicate this change.  Geting AHC_OUTSB to work as a macro doing
conditional memory mapped I/O would have been too gross.

Stop setting STPWEN in the main driver and let the PCI front end do it

only reduces the maximum nesting level by 1 with the standard

wdintr(), but such interrupt handlers hurt anyway).

the PCI probe code didn't include this file.

Fix some problems with the new sync and wide negotiation code.  First off,
go back to async transfers by using a message reject again.  The SCSI II and
III spec indicate that if a target's response to an initiater does not suit
(i.e. its too low), then performing a message reject is the appropriate
response.  If, on the other hand, the initiator begins the negotiation and
we want to go async, we will send back an SDTR message with a 0 period and
offset.

Also fix a really bad negotiation problem caused by a missing "break".  This
would usually hit people that had "smart" wide devices that immediately
attempt sync negotiation after a successful wide negotiation.

	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

Søren Schmidt 66e7fce7ac Use the calibrated/adjustable i8254 frequency `timer_freq' instead of
TIMER_FREQ.

Fixed missing splx() in scrn_timer().  The bug was harmless because of the
undocumented behaviour that the ipl is automatically restored for timeout
functions (see softclock()).  Perhaps we should depend on this behaviour.

Fixed the ddb fix in rev.1.176.  The in_debugger flag was no use because
it only works when the debugger is entered via the keyboard hotkey.  The
debugger may be entered for breakpoints and traps, and the console putc
routine has no way of knowing when it was, so the console putc routine
must (almost?) always remove the cursor image.

Not fixed: console switching in ddb doesn't work (ISTR it working), and
console 0 shouldn't be switched to for the debugger hotkey unless console
0 is /dev/console.

Fixed side effects from calling add_keyboard_randomness() in the console
getc routine by not calling it.  add_keyboard_randomness() currently
always reenables interrupts on 386's and 486's.  This is very bad if the
console getc routine is called from the debugger and the debugger was
entered with interrupts disabled.

Fixed preservation of initial screen and now-bogus comment about it.  It
was broken by setting the initial scr_buf to `buffer' instead of Crtat.
`buffer' was full of nulls and the first scroll cleared everything above
the things written through syscons.
