9fddcc6661 Fix our ioctl(2) implementation when the argument is "int". New
ioctls passing integer arguments should use the _IOWINT() macro.
This fixes a lot of ioctl's not working on sparc64, most notable
being keyboard/syscons ioctls.

Full ABI compatibility is provided, with the bonus of fixing the
handling of old ioctls on sparc64.

6621aa5cc7 Use the same method for detecting actual presence of AT-style keyboard
controller as we use in boot blocks (querying status register until
bit 1 goes off). If that doesn't happed during reasonable period assume
that the hardware doesn't have AT-style keyboard controller. This makes
FreeBSD working almost OOB on MacBook Pro (still there are issues with
putting second CPU core on-line, but since installation CD comes with
UP kernel with this change one should be able to install FreeBSD without
playing tricks with hints). Other legacy-free hardware (e.g. IBM NetVista
S40) should benefit from this as well, but since I don't have any I can't
verify.

It should make no difference on the ordinary i386 hardware (since in
that case that hardware already would be having an issues with A20
routines in boot blocks). I don't know much about AT-style keyboard
controller on other platforms (and don't have dedicated access to one),
therefore, the code is restricted to i386 for now. I suspect that amd64
may need this as well, but I would rather leave this decision to someone
who knows better about the platform(s) in question.

I have tested this change on as many "ordinary i386 boxes" as I can get
my hands on, and it doesn't create any false negatives on hardware with
AT-style keyboard present.

520b635320 - Hook up the new locations of the atkbdc(4), atkbd(4) and psm(4) source
files after they were repo-copied to sys/dev/atkbdc. The sources of
  atkbdc(4) and its children were moved to the new location in preparation
  for adding an EBus front-end to atkbdc(4) for use on sparc64; i.e. in
  order to not further scatter them over the whole tree which would have
  been the result of adding atkbdc_ebus.c in e.g. sys/sparc64/ebus. Another
  reason for the repo-copies was that some of the sources were misfiled,
  e.g. sys/isa/atkbd_isa.c wasn't ISA-specific at all but for hanging
  atkbd(4) off of atkbdc(4) and was renamed to atkbd_atkbdc.c accordingly.
  Most of sys/isa/psm.c, i.e. expect for its PSMC PNP part, also isn't
  ISA-specific.
- Separate the parts of atkbdc_isa.c which aren't actually ISA-specific
  but are shareable between different atkbdc(4) bus front-ends into
  atkbdc_subr.c (repo-copied from atkbdc_isa.c). While here use
  bus_generic_rl_alloc_resource() and bus_generic_rl_release_resource()
  respectively in atkbdc_isa.c instead of rolling own versions.
- Add sparc64 MD bits to atkbdc(4) and atkbd(4) and an EBus front-end for
  atkbdc(4). PS/2 controllers and input devices are used on a couple of
  Sun OEM boards and occur on either the EBus or the ISA bus. Depending on
  the board it's either the only on-board mean to connect a keyboard and
  mouse or an alternative to either RS232 or USB devices.
- Wrap the PSMC PNP part of psm.c in #ifdef DEV_ISA so it can be compiled
  without isa(4) (e.g. for EBus-only machines). This ISA-specific part
  isn't separated into its own source file, yet, as it requires more work
  than was feasible for 6.0 in order to do it in a clean way. Actually
  philip@ is working on a rewrite of psm(4) so a more comprehensive
  clean-up and separation of hardware dependent and independent parts is
  expected to happen after 6.0.

df616c9022 Make life for owners of Synaptics Touchpads more pleasant :-)
o Implement a shiny new algorithm to keep track of finger movement at

   language from users trying to resize windows.

 o Properly catch the many extra buttons and dials which manufacturers
   are known to screw onto Synaptics touchpad controllers.  Currently,
   up to seven buttons are known to work, more should work too.

 o Add a number of sysctls allowing one to tune the driver to taste in
   a simple way:

     # Should the extra buttons act as axes or as middle button
     hw.psm.synaptics.directional_scrolls

     # These control the 'stickiness' at low speeds

 o Introduce hw.psm.tap_threshold and hw.psm.tap_timeout to control
   the behaviour of taps on touchpads.  People might like to fiddle
   with these if tapping seems to slow or too fast for them.

5fb0f52712 Improve sync recovery algorithm:
o Remove PSM_SYNCERR_THRESHOLD1.  This value specified how many sync
   errors were required before the mouse is re-initialised.
   Re-initialisation is now done after (packetsize * 2) sync errors as
   things aren't likely to improve after that.

 o Reset lastinputerror when re-initialisation occurs.  We don't want
   to continue to drop data after re-initialisation.

 o Count the number of failed packets independently of the syncerrors
   statistic.  syncerrors is useful for recovering sync within a single
   packet.  pkterrors allows us to detect when the mouse changes its
   packet mode due to some external event (e.g. KVM switch).

 o Reinitialize the mouse if we see more than psmpkterrthresh errors
   during the validation period.  The validation period begins as soon
   as a sync error is detected and continues until psmerrsecs/msecs
   time has elapsed.  The defaults for these two values force a reset
   if we see two packet errors in a 2 second period.  This allows rapid
   detection of packet framing errors caused by the mouse changing packet
   modes.

 o Export psmpkterrthresh as a sysctl

 o Export psmloglevel as a sysctl.

 o Enable more debugging code to be enabled at runtime via psmloglevel.

 o Simplify verbose conditioned loging by using a VLOG macro.

 o Add several comments describing the sync recovery algorithm of
   this driver.

this avoids a bug in their mouse emulation that sends back incorrect

de75fd6d2b Significantly reduce the "jitter" that is typical for PS/2 mice
when using a KVM.

There is no actual solution possible, but this gets us pretty close.

Typically when switching back to a FreeBSD box and moving the mouse
wild data is produced, because the protocol's validation/checksum
system is extremely weak it is impossible to determine that we're
out of sync before dropping several bogus packets to user land.

The actual solution that appears to offer the best clamping of
jitter is to buffer the mouse packets if we've not seen mouse
activity for more than .5 seconds.  Then waiting to flush that data
for 1/20th of a second.  If within that 20th of a second we get any
packets that do fail the weak test we drop the entire queue and
back off accepting data from the mouse for 2 seconds and then repeat
the whole deal.

You can still get _some_ jitter, notably if you switch to the FreeBSD
box, then move the mouse just enough to generate one or two packets.
Those packets may be bogus, but may still pass the validity check.

One way to finally kill the problem once and for all is to check
the initial packets for "wild" values.  Typically one sees packets
in the +/-60 range during normal operation, however when bogus data
is generated it's typically near the outer range of +/-120 or more,
those packets would be a good candidate for dropping or clamping.

I've been running with this for several weeks now and it has
significantly helped me stay sane even with a piece of junk Belkin
KVM causing wild jitter each and every time I switch.

Lastly I'd like to note that my experience with Windows shows me that
somehow the Microsoft PS/2 driver typically avoids this problem, but
that may only be possible when running the mouse in a dumb-ed down PS/2
mode that Belkin recommends on their site.
