a986a974e9 It seems that I slipped a nasty bug into the CAPI support. The message
lengths for CONNECT_REQ and CONNECT_IND are incorrect, which causes
dialouts to fail after certain error situations (an invalid -- not
wrong! -- number has been dialed). Since these messages are tagged as
too short, the device reads trailing garbage as the B protocol
parameters; this is OK as long as the garbage consists of zero bytes,
which it usually does, except after the said error.

Another change we have taken into use is to send an explicit Q.850
"normal call clearing" code when a call is ignored using PRI equipment
(specifically AVM T1); the CAPI pseudo-code for ignore, 1, translates
into something at least Ericsson exchanges interpret oddly (message
"this area is not reachable from your number"). NCCLR makes the exchange
give a busy signal, which is the behaviour at least we prefer
(conceivably, the ignore code could be made a sysctl variable).

The attached patch corrects the message length issue. It also includes a
somewhat unpretty solution for the PRI ignore code (if device's number
of channels equals 30, assume PRI and send NCCLR, otherwise send CAPI
ignore). Tested using AVM B1 PCI and T1 PCI.

Added FPU_ERROR_BROKEN option.  This forces a successful probe for

f2465b0df3 Remove this driver from FreeBSD.
Jonathon Lemon's driver (gx) is at least as fast and has more features
and is likely to be better supported.

It is also possible that Intel might support this chipset in FreeBSD
with their own driver. Somewhat secretive and furtive rumblings from
certain Yahoo employees have indicated that this might happen soon.

I'm a little unhappy at the lack of discussion on the net list about
this, or on developers, or on hackers, or the lack of mention on
audit. This then leaves me to try and figure out the right thing
to do.

I've concluded that the right thing to do is to remove wx from FreeBSD,
as this is probably best for FreeBSD.

140bf733a7 Fix a bug in the kernel entry window handling where the wrong register
was used.  This resulted in bogus bad window traps (invalid wstate).

Add a trace to sfsr traps (alignment among other things).

Use KTR_TRAP instead of KTR_CT1.

Use the right registers when storing the values of various
mmu registers into the trap frame.  This fixes a bug where sometimes
the context number reported by a fault would be garbage.  Sometimes
it would be zero for faults on user address space so the kernel would
wrongly think that it was a fault on kernel address space and fail.

Use the preloaded registers in the vectored interrupt trap instead
of reading pointers from memory.  Remove traces due to register
pressure and excess verbosity.  We can probably still sneak in one
trace.  Remove some debug code.

Go back to using the tsb register during kernel page table lookups.
This is the best way to not have to have the address of the kernel tsb be
a compile time constant.  We lie and say we have 1 page tsb when really
its much larger.  This way the hardware provides bits 13-22 of the
virtual address (the lower 9 bits of the virtual page number) in the
form of the address of the tte corresponding to the fault address in
the (1 page) kernel tsb.  With some clever arithmetic we can then get
bits 22 and up from the tte tag and add them to the tte address in
order to index massive tsbs (basically unlimited).

Add traps for physical address hardware watchpoints.

Don't try to pass the window state from the trap table entry point
all the way down to the common trap code.  Its too easy to clobber
and reading it again doesn't cost much.

Fixup some traces.

Fiddle the cwp bits on return from the kernel to user mode so that
the window we are returning to is always the same as the one we
restore to in the trap code.  Strictly speaking this is not necessary,
it only affects return from fork and exec, but setting up the windows
right would require hard coding the right cwp values in cpu_fork and
setregs, basically hard coding the number of frames between syscall and
tl0_ret.  The result of getting it wrong is usually a spill to an invalid
stack pointer; either 0 or pointing into kernel space.  This should also
alleviate the need to context switch the cwp.

Transfer the trap state from locals to alternate globals in the trap
return code so that we can do a restore and rotate the windows before
reloading the trap registers.  If the restore fails we'll trap back
into the kernel, so there's no point in loading the trap registers
before hand.  Its is crucial that the window trap recovery code not
clobber the alternate globals.

2baa1ef450 Align the symbol that demarks the end of the signal code on a 16 byte
boundary.  It must be on at least an 8 byte boundary so that the length
of the signal code is a multiple of 8 (well aligned).  The size is used
in the calculation of the address of the argument and environment vectors
on the user stack; getting it wrong results in the string pointers being
misaligned and causes alignment faults in getenv() among other things.

Allocate a regular stack frame below the signal frame on the user stack
and join up the frame pointer to the previous frame.  This fixes longjmp-ing
out of signal handlers.  Longjmp traverses the stack upwards in order to
find the right frame to return to, so the frame pointers must join up
seamlessly.  I thought this would just work, but obviously the frame
needs to be below the signal frame, not above it like before.  Account
for the extra space in the signal code.

Preload pointers to interrupt data structures in interrupt globals.
This avoids the need to load the pointers from memory in the vectored
interrupt trap handler.

Transfer the first 2 out registers into td_retval in setregs.  We use
the same registers for system call arguments as return values, so these
registers got clobbered by the system call return values on return from
execve.  They now get clobbered by the right values.  We must put the values
in both the out registers in the trapframe and in td_retval because init
calls exec but fails to transfer the return value into the out registers.
This fixes a bug where the first exec after init would pass junk to the
c runtime, instead of a pointer to the argument strings.  A better solution
would be to return EJUSTRETURN on success from execve.

Adjust for change in pmap_bootstraps prototype.

Map the message buffer after the trap table is setup.  We will fault
on it immediately.

72ec63a53d Introduce some jitter to the timing of the samples that determine
the system load average. Previously, the load average measurement
was susceptible to synchronisation with processes that run at
regular intervals such as the system bufdaemon process.

Each interval is now chosen at random within the range of 4 to 6
seconds. This large variation is chosen so that over the shorter
5-minute load average timescale there is a good dispersion of
samples across the 5-second sample period (the time to perform 60
5-second samples now has a standard deviation of approx 4.5 seconds).

5577bd2bca Rework pmap so that it separates the PTE structure from the pv_entry
structure. This makes it possible to pre-allocate PTEs for the kernel,
which is necessary for a reliable implementation of pmap_kenter(). This
also avoids wasting space (about 48 bytes per page) for kernel mappings
and user mappings of memory-mapped devices.

This also fixes a bug with the previous version where the implementation
required the pv_entry structure to be physically contiguous but did not
enforce this (the structure size was not a power of two). This meant
that the pv_entry free list was quickly corrupted as soon as the system
was even mildly loaded.

3c7b85d4f0 Fix Alpha related brokenness. We used to have a MD linux_ioctl.h
that appeared to be very different from the MI version. These
differences were mostly bogus and caused by copying octal
definitions and write them as hexadecimal values without doing
any base conversion (ie 010 was copied to 0x10). After filtering
out these differences, any remaining (real) incompatibilities
have been merged into the MI header file to make them more visible.

While here, fix the termios <-> termio conversion WRT to the c_cc
field for Alpha. The termios values do not match the termio values
and thus prevents us from copying.

By eliminating the Alpha MD copy of linux_ioctl.h we also fixed
the recent build breakage caused by putting new bits in the MI
header and not in the MD header.

265e95d904 Deleted most of npxprobe(), and merged npxprobe1() back into npxprobe().
Use the normal interrupt handler (npx_intr()) instead of a special
probe-time interrupt handler, although this causes problems due to
the bus_teardown_intr() not actually even tearing down the interrupt
(these problems were avoided by doing interrupt attachment for the
special interrupt handler directly).  Fixed minor bitrot in comments.

The reason for the npxprobe()/npxprobe1() split mostly went away at
about the same time it was made (in 1992 or 1993 just before the
beginning of history).  386BSD ran all probes with interrupts completely
masked, and I didn't want to disturb this when I added an irq probe
to npxprobe().  An irq (not necessarily npx) must be acked for at least
external npx's to take the cpu out of the wait state that it enters
when an npx error occurs, so the probe must be done with a suitable
irq unmasked.  npxprobe() went to great lengths to unmask precisely
the npx irq.

Running probes with all interrupts masked was never really needed in
FreeBSD, since FreeBSD always masked interrupts well enough using
splhigh(), but it wasn't until rev.1.48 (1995/12/12) of autoconf.c
that all probes were run with CPU interrupts enabled.  This permits
npxprobe() to probe its irq using normal interrupt resources.  Note
that most drivers still can't depend on this.  It depends on the
interrupt handler being fast and the irq not being shared.

2504f76272 Commit my old fixes for cosmetic bugs in npxprobe() so that they aren't
lost when the buggy code goes away completely:
- don't assume that the npx irq number is >= 8.  Rev.1.73 only reversed
  part of the hard-coding of it to 13 in rev.1.66.
- backed out the part of rev.1.84 that added a highly confused comment
  about an enable_intr() being "highly bogus".  The whole reason for
  existence of npxprobe() (separate from the main probe, npxprobe1())
  is to handle the complications to make this enable_intr() safe.
- backed out the part of rev.1.94 that modified npxprobe().  It mainly
  broke the enable_intr() to restore_intr().  Restoring the interrupt
  state in a nested way is precisely what is not wanted here.  It was
  harmless in practice because npxprobe() is called with interrupts
  enabled, so restoring the interrupt state enables interrupts.  Most
  of npxprobe() is a no-op for the same reason...

819e7ffdf3 Whack on this soon to be deprecated driver.
What the heck, the OpenBSD version will benefit.

1. Add wx_txint_delay as a tunable (defaults to 5000 now, or ~5ms) and switch
to using delayed TXDW interrupts. Since the chip continues to reload the
TIDV with this value for each descriptor written back, this allows continued
deferral of the actual interrupt until the last packet completes (assuming
that 5ms between multiple packets transmitting is reasonable).

2. Add two other SYSCTL entities:

hw.wx.dump_stats
hw.wx.clear_stats

to be used, hackey hackey, to get the watchdog routine to dump/clear
the current softc statistics.

Usage would be:

	sysctl -w hw.wx.dump_stats=UNIT

to cause the current stats to be dumped for UNIT.

3. Attempt to clean up wx_detach routine so we don't panic. Well, things
still panic, but given that the code is just like other NIC drivers,
I suspect it's actually something elsewhere, like e1000phy, that's actually
blowing up.

4. Skip the entire test for runt packets- after doing somet thinking
and experimenting, I believe that the chip only doesn't like it if
the whole frame to xmit is < 16 bytes- each TFD can be some fragment
of that. This should improve performance a chunk because of all of the
(14 byte ETHERHEADER + DATA) mbuf chains.

5. Keep track of total frame length. Try not to xmit an odd byte frame-
this is supposed to get around some dumb Cisco switch problems.

6. On the last packet, also set Interrupt Delay && Report Packet Sent
(see #1 above)

7. Attempt to do xmit garbage collection *first* in order to avoid setting
IFF_OACTIVE if at all possible.

422ec2ace1 Save WIP. Partial rewrite of cpu_switch() and savectx(). This makes it closer
to working but still needs some work to properly switch the full context
(such as saving the fpu registers, switch stacks, etc.).  Also, remove some
dead code that was mixed in.

10ad529832 Change vmapbuf() to use pmap_qenter() and vunmapbuf() to use pmap_qremove().
This significantly reduces the number of TLB shootdowns caused by
vmapbuf/vunmapbuf when performing many large reads from raw disk devices.

e7673b8424 Fix locking violations during page wiring:
- vm map entries are not valid after the map has been unlocked.

 - An exclusive lock on the map is needed before calling
   vm_map_simplify_entry().

Fix cleanup after page wiring failure to unwire all pages that had been
successfully wired before the failure was detected.

8166ba27bd Hack for the "out-of-sync" error.
- Count the number of this error.
- When the error is detected for the first time, the psm driver will
  throw few data bytes (up to entire packet size) and see if it can
  get back to sync.
- If the error still persists, the psm driver disable/enable the mouse
  and see if it works.
- If the error still persists and the count goes up to 20,
  the psm driver reset and reinitialize the mouse. The counter
  is reset to zero.
- It also discards an incomplete data packet when the interval
  between two consequtive bytes are longer than pre-defined timeout
  (2 seconds).  The last byte which arrived late will be regarded as
  the first byte of a new packet.  This is louie's idea.

You may see the following error logs during the above operations:

  "psmintr: delay too long; resetting byte count"
  "psmintr: out of sync (%04x != %04x)"
  "psmintr: discard a byte (%d)"
  "psmintr: re-enable the mouse"
  "psmintr: reset the mouse"

kernel map and object in a manner that contigfree() is actually able to
free.  Previously contigfree() freed up the KVA space but could not
unwire & free the underlying VM pages due to mismatched pageability between
the map entry and the VM pages.

00a6f47f13 Finally fix the VM bug where a file whos EOF occurs in the middle of a page
would sometimes prevent a dirty page from being cleaned, even when synced,
resulting in the dirty page being re-flushed to disk every 30-60 seconds or
so, forever.  The problem is that when the filesystem flushes a page to
its backing file it typically does not clear dirty bits representing areas
of the page that are beyond the file EOF.  If the file is also mmap()'d and
a fault is taken, vm_fault (properly, is required to) set the vm_page_t->dirty
bits to VM_PAGE_BITS_ALL.  This combination could leave us with an uncleanable,
unfreeable page.

The solution is to have the vnode_pager detect the edge case and manually
clear the dirty bits representing areas beyond the file EOF.  The filesystem
does the rest and the page comes up clean after the write completes.

instruction.  Stefan Keller <dres@earth.serd.org> noticed that CPU
identification was broken when compiled with -O2, and tracked it
down to the asm statement, which was storing values into memory
without specifying that memory was modified.  He submitted a patch
which added "memory" as a clobber, but I refined it further to
arrive at this version.
