Better diagnostics.  No other functional change.

wsmouse: add support for "precision scrolling" events and (GET|SET)PARAMS

WSCONS_EVENT_HSCROLL and WSCONS_EVENT_VSCROLL are two new wscons event
types that allow scrolling with a higher precision ("smoothness") than an
emulated scroll wheel, and are useful for touch input drivers.

WSMOUSEIO_GETPARAMS and WSMOUSEIO_SETPARAMS are two new ioctls that allow
the speed and direction of precision scrolling to be configured.

both features were originally implemented in OpenBSD.

Sync w/ HEAD.

Explicitly include generated ioconf.h for struct cfdrivers.

update from HEAD

Remove redundant includes of malloc.h

Use __arraycount a bunch
Also, DIAGNOSTIC panic -> KASSERT

Remove more unnecessary #include for sys/localcount.h

Restore all work from the former pgoyette-localcount branch (which is
now abandoned doe to cvs merge botch).

The branch now builds, and installs via anita.  There are still some
problems (cgd is non-functional and all atf tests time-out) but they
will get resolved soon.

Rename LOCALCOUNT_INITIALIZER to DEVSW_MODULE_INIT.  This better describes
what we're doing, and why.

Instead of repeatedly typing the conditional initialization of the
.d_localcount members in the various {b,c}devsw, define an initializer
macro and use it.  This also removes the need for defining new symbols
for each 'struct localcount'.

As suggested by riastradh@

Rump drivers are always installed via devsw_attach() so we need to
always allocate a 'struct localcount' for these drivers whenever they
are built as modules.

Rebase to HEAD as of a few days ago.

Rebase.

Add d_discard to all struct cdevsw instances I could find.

All have been set to "nodiscard"; some should get a real implementation.

for a reference, the tree before this commit was tagged

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

Change (mostly mechanically) every cdevsw/bdevsw I can find to use
designated initializers.

I have not built every extant kernel so I have probably broken at
least one build; however I've also found and fixed some wrong
cdevsw/bdevsw entries so even if so I think we come out ahead.

Correct copy/paste error in previous.

Initialize the W axis value on open as is already done for the other axes.

- after some discussion with agc@ i agreed it would be a good idea to move

- sbin/init: Run devfsd -s before going to multiuser.

- sys/arch: Provide arm32, i386, sparc with a mem_init() function to request
  	    device nodes for /dev/null, /dev/zero, etc.

- sys/dev: Convert rnd, wd, agp, raid, cd, sd, wsdisplay, wskbd, wsmouse,
	   wsmux, tty, bpf, swap to devfs New World Order.

- sys/fs/devfs: Make the visibility attribute of device nodes configurable.
	        Also provide a function to mount a devfs on boot.

- sys/kern: Add a new boot flag, -n. This disables devfs support. Unless
	    the -n flag is specified the kernel will mount a devfs file
	    system on boot.

Split device_t and softc for wskbd(4), wsmouse(4) and that creepy wsmux(4).

Refactor PNP API:
- Make suspend/resume directly a device functionality. It consists of
  three layers (class logic, device logic, bus logic), all of them being
  optional. This replaces D0/D3 transitions.
- device_is_active returns true if the device was not disabled and was
  not suspended (even partially), device_is_enabled returns true if the
  device was enabled.
- Change pnp_global_transition into pnp_system_suspend and
  pnp_system_resume. Before running any suspend/resume handlers, check
  that all currently attached devices support power management and bail
  out otherwise. The latter is not done for the shutdown/panic case.
- Make the former bus-specific generic network handlers a class handler.
- Make PNP message like volume up/down/toogle PNP events. Each device
  can register what events they are interested in and whether the handler
  should be global or not.
- Introduce device_active API for devices to mark themselve in use from
  either the system or the device. Use this to implement the idle handling
  for audio and input devices. This is intended to replace most ad-hoc
  watchdogs as well.
- Fix somes situations in which audio resume would lose mixer settings.
- Make USB host controllers better deal with suspend in the light of
  shared interrupts.
- Flush filesystem cache on suspend.
- Flush disk caches on suspend. Put ATA disks into standby on suspend as
  well.
- Adopt drivers to use the new PNP API.
- Fix a critical bug in the generic cardbus layer that made D0->D3
  break.
- Fix ral(4) to set if_stop.
- Convert cbb(4) to the new PNP API.
- Apply the PCI Express SCI fix on resume again.

PR/32794: Paul Shupak: Panic in wsmouse code.
Checking the number of events after you've trashed the stack is not very
useful. Instead, break out of the loop if we ran out, printing a message.
Also don't try to inject 0 events; reset our state instead. Maybe having
0 events should be a diagnostic printf at this point? Anyway it is not
nice having the kernel die because the mouse code got confused. Finally,
explain why the array of events is sized funny.

wsevent cleanup:

- Add a wsevent_inject function that atomically adds a set of events to an
  event queue and change all code that directly messed with a queue to use it.
- Replace the WSEVENT_WAKEUP macro with a regular function.
- Make WSEVENT_QSIZE, PWSEVENT and splwsevent private definitions to
  wsevent.c, instead of exposing them in the header file.
- Make the wsevent_init function take a process to attach to the queue,
  instead of leaving this task to the caller (which always did it).

Reviewed in tech-kern@.

Add support to automatically repeat mouse button events in wsmouse(4) and
change wsconsctl(4) so that this is configurable.

This is specially useful for mice that provide page up/down buttons instead
of a real wheel and that do not send events repeatedly from the hardware.
(E.g.: Logitech Marble Mouse.)

No objections in tech-kern@.

Adapt for timecounters: mostly use get*time() and use "time_second"
instead of "time.tv_sec".

Some devices provide more than three (X, Y, and Z) "directions".  So add
a W "coordinate" that can be used for these.
This changes the type of wsmouse_input().  To avoid changing a lot of drivers
a compatibilty #define is provided.  Maybe changing all drivers would have
been better?

cleanup & uniform descriptor owner handling:

  these routines instead of custom code where appropriate
* make every place handling TIOCSPGRP/TIOCGPGRP handle also FIOSETOWN/FIOGETOWN
  properly, and remove the translation of FIO[SG]OWN to TIOC[SG]PGRP
  in sys_ioctl() & sys_fcntl()
* also remove the socket-specific hack in sys_ioctl()/sys_fcntl() and
  pass the ioctls down to soo_ioctl() as any other ioctl

change discussed on tech-kern@

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

Apply the aborted ktrace-lwp changes to a specific branch.  This is just for
others to review, I'm concerned that patch fuziness may have resulted in some
errant code being generated but I'll look at that later by comparing the diff
from the base to the branch with the file I attempt to apply to it.  This will,
at the very least, put the changes in a better context for others to review
them and attempt to tinker with removing passing of 'struct lwp' through
the kernel.

Back out the lwp/ktrace changes. They contained a lot of colateral damage,
and need to be examined and discussed more.

Pass lwp pointers throughtout the kernel, as required, so that the lwpid can
be inserted into ktrace records.  The general change has been to replace
"struct proc *" with "struct lwp *" in various function prototypes, pass
the lwp through and use l_proc to get the process pointer when needed.

merge kqueue branch into -current

kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals

kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)

based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe

Merge the gehenna-devsw branch into the trunk.

This merge changes the device switch tables from static array to
dynamically generated by config(8).

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

Improve debug messages a little.

Change back to have a wseventvar in the softc for event sources.  This

Also add some more debug stuff.

Major rototilling of the wsmux code.  No user visible changes (except that
many bugs have been fixed).
Changes:
The wskbd, wsmouse, and wsmux are now "sub-classes" of wsevsrc, which is
a source of ws events.  This make the structure of those drivers a little
more uniform.
Many bug fixes involving adding and removing devices from muxes.
When a kernel is configured without wsmux there will now be none (unlike
before where you got a console mux anyway).
The kernel now compiles with all combinations of ws devices present.

Catch up to -current.

Fix a (very old) pasto.

ANSIfy.

Two changes to the wsmux code:
* Allow the wsmux used by wsdisplay for the keyboard(s) to be explicitely
  specified with the kbdmux locator.
* Allow keyboards and mice that have a mux to be opened in the regular way.
These changes should be totally backwards compatible.

* add a VCLONED vnode flag that indicates a vnode representing a cloned
  device.
* rename REVOKEALL to REVOKEALIAS, and add a REVOKECLONE flag, to pass
  to VOP_REVOKE
* the revoke system call will revoke all aliases, as before, but not the
  clones
* vdevgone is called when detaching a device, so make it use REVOKECLONE
  to get rid of all clones as well
* clean up all uses of VOP_OPEN wrt. locking.
* add a few VOPS to spec_vnops that need to do something when it's a
  clone vnode (access and getattr)
* add a copy of the vnode vattr structure of the original 'master' vnode
  to the specinfo of a cloned vnode. could possibly redirect getattr to
  the 'master' vnode, but this has issues with revoke
* add a vdev_reassignvp function that disassociates a vnode from its
  original device, and reassociates it with the specified dev_t. to be
  used by cloning devices only, in case a new minor is allocated.
* change all direct references in drivers to v_devcookie and v_rdev
  to vdev_privdata(vp) and vdev_rdev(vp). for diagnostic purposes
  when debugging race conditions that still exist wrt. locking and
  revoking vnodes.
* make the locking state of a vnode consistent when passed to
  d_open and d_close (unlocked). locked would be better, but has
  some deadlock issues

Add kqueue support to wscons events.

Commit my "devvp" changes to the thorpej-devvp branch.  This
replaces the use of dev_t in most places with a struct vnode *.

This will form the basic infrastructure for real cloning device
support (besides being architecurally cleaner -- it'll be good
to get away from using numbers to represent objects).

Fix an uninitialised variable which could have caused corruption of the user

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

Mouse move event should be made before mouse bown event. Without that,
you may got a mouse down event in strange plase.

Absolute pointing device support.
 - Wsmouse_input() get new argument 'flag', which indicates whether x/y/z are
   relative or absolute.
 - Wsmouse get new io controls, WSMOUSEIO_SCALIBCOORDS and
   WSMOUSEIO_GCALIBCOORDS.

replace embedded _rcsid[] string by __KERNEL_RCSID(), remove _copyright[]

Get the dependencies on NWSMUX right (I hope).

Update from trunk.

Add the wsmux pseudo device.

Sync w/ -current.

Make it possible to detach wsmouse and wskbd.
XXX wskbd probably needs some more work.

Remove redundant test if the unit numbers is in range.

Allow the wsmouse device to be opened for writing even if it is already
open, this way ioctl() can be performed on it and wsconsctl works.

add third axis for pointing devices (flying mice)

Insert lots of ``#if NWSMOUSE > 0'' and ``#if NWSDISPLAY > 0'' to make it
possible to have a wsmouse and/or wskbd without having a wsdisplay.
