This tunable allows one to enable (1) or disable (0) gestures like tap
and tap-hold on Synaptics TouchPad when the Extended mode isn't enabled
(ie. "hw.psm.synaptics_support" not set).
By default, the value is -1 in order to keep the current behaviour of
not enabling/disabling gestures explicitly.

The newbus lock is responsible for protecting newbus internIal structures,
device states and devclass flags. It is necessary to hold it when all
such datas are accessed. For the other operations, softc locking should
ensure enough protection to avoid races.
Newbus lock is automatically held when virtual operations on the device
and bus are invoked when loading the driver or when the suspend/resume
take place. For other 'spourious' operations trying to access/modify
the newbus topology, newbus lock needs to be automatically acquired and
dropped.
For the moment Giant is also acquired in some key point (modules subsystem)
in order to avoid problems before the 8.0 release as module handlers could
make assumptions about it. This Giant locking should go just after
the release happens.
Please keep in mind that the public interface can be expanded in order
to provide more support, if there are really necessities at some point
and also some bugs could arise as long as the patch needs a bit of
further testing.
Bump __FreeBSD_version in order to reflect the newbus lock introduction.

After I removed all the unit2minor()/minor2unit() calls from the kernel
yesterday, I realised calling minor() everywhere is quite confusing.
Character devices now only have the ability to store a unit number, not
a minor number. Remove the confusion by using dev2unit() everywhere.
This commit could also be considered as a bug fix. A lot of drivers call
minor(), while they should actually be calling dev2unit(). In -CURRENT
this isn't a problem, but it turns out we never had any problem reports
related to that issue in the past. I suspect not many people connect
more than 256 pieces of the same hardware.

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.

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.

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

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.
