01fef73008 Don't mark unallocated resources as active; the goal is to reserve them,
and there may be a good reason for them being unallocated (eg. they're
nonsensical or not useful).  The goal here is simply to reserve them
against accidental use by other code.

a9d565fcd2 Don't do device_set_desc() until after checking for PnP probes. Otherwise
things like sound cards can get called "Parallel port".  A note to the
unwary; the isa-pnp devices in the system are probed like PCI - each
device ID is passed to *all* isa probe routines to find the best match.
If the driver is not prepared to deal with this, it must abort in this
scenario or it will try and claim all PnP devices.

0f210c922b Port of ppbus standalone framework to the newbus system.
Note1: the correct interrupt level is invoked correctly for each driver.
       For this purpose, drivers request the bus before being able to
       call BUS_SETUP_INTR and BUS_TEARDOWN_INTR call is forced by the ppbus
       core when drivers release it. Thus, when BUS_SETUP_INTR is called
       at ppbus driver level, ppbus checks that the caller owns the
       bus and stores the interrupt handler cookie (in order to unregister
       it later).

       Printing is impossible while plip link is up is still TRUE.
       vpo (ZIP driver) and lpt are make in such a way that
       using the ZIP and printing concurrently is permitted is also TRUE.

Note2: specific chipset detection is not done by default. PPC_PROBE_CHIPSET
       is now needed to force chipset detection. If set, the flags 0x40
       still avoid detection at boot.

Port of the pcf(4) driver to the newbus system (was previously directly
connected to the rootbus and attached by a bogus pcf_isa_probe function).

35e61cbd71 Add a new mechanism, cndbctl(), to tell the console driver that
ddb is entered.  Don't refer to `in_Debugger' to see if we
are in the debugger.  (The variable used to be static in Debugger()
and wasn't updated if ddb is entered via traps and panic anyway.)

- Don't refer to `in_Debugger'.
- Add `db_active' to i386/i386/db_interface.d (as in
  alpha/alpha/db_interface.c).
- Remove cnpollc() stub from ddb/db_input.c.
- Add the dbctl function to syscons, pcvt, and sio. (The function for
  pcvt and sio is noop at the moment.)

b6e5f28e51 Futher cleanup.. "device_print_prettyname(); printf()" -> device_printf()
It seems that the IDE system uses 0x3f6 for itself, which conflicts with
fdc's default 0x3f0-3f7 allocation range. Sigh.  Work around this.
Use bus_set_resource() rather than allocating specific areas, it makes
the code a little cleaner.

3b1782065f Merge most of FDC_YE into the mainline driver.
o Rename FDC_PCMCIA to FDC_NODMA to allow systems that don't have dma
  for floppies.
o Remove all but two FDC_YE ifdefs.  They aren't needed.
o Move defines for YE_DATAPORT to fdreg.h.

Not fixed:
o The pccard probe/attach.  However, motivated individuals can more
  easily add this now.

This is a merge of changes I've had in my tree for a long time.  These
fixes were tested on my VAIO with its normal floppy.  Please let me

b9da888fcb Make the evil broken pnpbios compensation slightly less evil.
This is the hack that compensates for when bios vendors "forget" to
include the fdc control (0x3f7) port in their io port mappings.  Instead
of accessing ports outside of a range allocated to a handle, simply
allocate the port directly.  It even shows up in the probe..

37286586ff Patch up some of the evilness left over from the early newbus porting.
In particular:
 - Don't leave resources allocated in the probe routine.  Allocate them
   during probe and release them.  Probe's job is to identify devices only.
 - Don't abuse the ivars pointer.. (!).  Create real ivars and use the
   proper access system.  (the bus_read_ivar method)
 - Don't add the children until attach() has successfully grabbed the
   hardware, otherwise there are potential leaks if attach fails.

82916a1126 ISA device drivers use the ISA source interrupt number in locations where
the low level interrupt handler number should be used.  Change
setup_apic_irq_mapping() to allocate low level interrupt handler X (Xintr${X})
for any ISA interrupt X mentioned in the MP table.

Remove an assumption in the driver for the system clock (clock.c) that
interrupts mentioned in the MP table as delivered to IOAPIC #0 intpin Y
is handled by low level interrupt handler Y (Xintr${Y}) but don't assume
that low level interrupt handler 0 (Xintr0) is used.

Don't allocate two low level interrupt handlers for the system clock.

0f19e631e2 Fixed races accessing the RTC. The races apparently caused
apm_default_resume() to sometimes set a very wrong time.
(1) Accesses to the RTC index and data registers were not atomic enough.
    Interrupts were not masked.  This was only good enough until an
    interrupt handler (rtcintr()) started accessing the RTC in FreeBSD-2.0.
(2) Access to the block of time registers in inittodr() was not atomic
    enough.  inittodr() has 244us to read the time registers.  Interrupts
    were not masked.  This was only good enough until something (apm)
    started calling inittodr() after boot time in FreeBSD-2.0.
The fix for (2) also makes the timecounter update more atomic, although
this is currently unimportant due to the low resolution of the RTC.

684fb19e34 Extract a list of extra isa pnp modem ID's from NetBSD and OpenBSD. Some
of these are bound to have a PNP05xx compatid, but there's no easy way to
tell.  Since it's just an ID list and uses the pnp header's description
strings rather than encoding strings here, it doesn't seem to be too
expensive to err on the safe side.

While i was at it, i (partially) fixed option FCC_YE since it would no

a2639a184d Add a truely evil workaround (hack!) for some unfortunate BIOS
programming practices.  It seems that newer fdc chips have an
alternative way of setting the transfer speed (including high speed
modes for floppy tape) that doesn't use the control register (which
we don't support - we use the old way only).  So, they (the BIOS
programmers) sometimes leave out the 0x3f6 control register from
the PnP ports descriptor(!!).  "Hey, it works with windows, so
what's the problem?" :-(  Anyway, this hack tries to compensate
for that.  This was discussed with dfr (who did the pnp attachment).

d0029cf5f3 Use bus_get_resource() instead of bus_get_resource_start() as the latter
returns "0" on failure, which is indistinguishable from (say) irq 0.  This
should stop a couple of stray messages that turn up.

Also, if a BUS_SETUP_INTR() fails with INTR_TYPE_FAST, try falling back to
a normal interrupt.  This might help pccard folks with a shared slot
interrupt.  This whole thing needs to be revisited.

fe0d408987 Remove the 'ivars' arguement to device_add_child() and
device_add_child_ordered().  'ivars' may now be set using the
device_set_ivars() function.

This makes it easier for us to change how arbitrary data structures are
associated with a device_t.  Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.

Despite my best efforts I've probably forgotten something so let me know
if this breaks anything.  I've been running with this change for months
and its been quite involved actually isolating all the changes from

e09f49b6fa Fix the hang on card eject problem and maybe the hang on suspend
problem.

o Create new timeout routine so we don't detach the card inside a ISR
  but instead drop back to spl0 via a timeout of 0.
o Actually delete the child of the pccard device rather than just faking
  it badly.
o Fix sio, ed and ep to have pccard detach routines that are int rather
  than void.
o Fix ep and ed pccard detach routines to use if_detach rather than just
  if_down.  if_detach destroys the device, while if_down just marks it
  down.  In this incarnation of the pccard things, we map the disable
  the slot action to detach the driver, which removes the driver from the
  device tree.  When that is done, a panic would soon follow as the
  ifconfig tried to down the device.

Didn't fix:
o Should cache the pccard dev child's pointer in struct slot
o remove now unused parts of struct slot
o Any driver using softc after detach has been called.  sio's softc used
  to be statically allocated, so you could check sc->gone, but that is
  now gone.
o Didn't remove gone from softc of drivers that use the old pccard method.

Didn't test:
o ed driver changes
o sio driver changes on pccards
o suspend (no laptop or apm support on my desktop)

- device_print_child() either lets the BUS_PRINT_CHILD

	  it prints "foo0: not found\n"

Alter sys/kern/subr_bus.c:bus_generic_print_child() to take on
the previous behavior of device_print_child() (printing the
"foo0: <FooDevice 1.1>" bit of the announce message.)

Provide bus_print_child_header() and bus_print_child_footer()
to actually print the output for bus_generic_print_child().
These functions should be used whenever possible (unless you can
just use bus_generic_print_child())

The BUS_PRINT_CHILD method now returns int instead of void.

Modify everything else that defines or uses a BUS_PRINT_CHILD
method to comply with the above changes.

	- Devices are 'on' a bus, not 'at' it.
	- If a custom BUS_PRINT_CHILD method does the same thing
	  as bus_generic_print_child(), use bus_generic_print_child()
	- Use device_get_nameunit() instead of both
	  device_get_name() and device_get_unit()

e33bfde398 We're called too early to have any idea whether APM is going to be
active or not.  The only sane thing we can do here is assume that if
APM is supported it might be active at some point, and bail.

In reality, even this isn't good enough; regardless of whether we support
APM or not, the system may well futz with the CPU's clock speed and throw
the TSC off.  We need to stop using it for timekeeping except under
controlled circumstances.  Curse the lack of a dependable high-resolution

- Reorganized the screen update routine.

- VT switching code is reorganized.  It now should be slightly more

- Added the DEVICE_RESUME function so that syscons no longer hooks the
  APM resume event directly.

- New kernel configuration options: SC_NO_CUTPASTE, SC_NO_FONT_LOADING,
  SC_NO_HISTORY and SC_NO_SYSMOUSE.

  reduced.

  SC_PIXEL_MODE

b50641ef9c Fixed glitches (jumps) of about 1/HZ seconds for the i8254 timecounter.
The old version only worked right when the time was read strictly
more often than every 1/HZ seconds, but we only guarantee reading
it every (1/HZ + epsilon) seconds.  Part of rev.1.126-1.127 attempted
to fix this but didn't succeed.  Detect counter rollover using the
heuristic from the old version of microtime() with additional
complications for supporting calls from fast interrupt handlers.
This works provided i8254 interrupts are not delayed by more than
1/(2*HZ) seconds.

This needs more comments, and cleanups for the SMP case, and more
testing of the SMP case before it is merged into RELENG_3.

Mark the GDB port in the config file with flags 0x80. Currently
only the sio driver checks these flags and sets up a GDB port,
but adding similar code to other serial drivers would be easy.
For backward compatibility, if an sio port is marked as the console
and no port is marked as the gdb port, the GDB port will be mapped
to the console port. This hack should go away at some point.

for allocation/deallocation tracking.  Releasing a resource clears the

including pci and isa.  I have only tested the EISA part of this so far.

6182fdbda8 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

e9deda23ae Keyboard driver update in preparation for the USB keyboard driver.
- Refined internal interface in keyboard drivers so that:
  1. the side effect of device probe is kept minimal,
  2. polling mode function is added,
  3. and new ioctl and configuration options are added (see below).

- Added new ioctl: KDSETREPEAT
  Set keyboard typematic rate.  There has existed an ioctl command,
  KDSETRAD, for the same purpose.  However, KDSETRAD is dependent on
  the AT keyboard.  KDSETREPEAT provides more generic interface.
  KDSETRAD will still be supported in the atkbd driver.

- Added new configuration options:
  ATKBD_DFLT_KEYMAP
  Specify a keymap to be used as the default, built-in keymap.
  (There has been undocumented options, DKKEYMAP, UKKEYMAP, GRKEYMAP,
  SWKEYMAP, RUKEYMAP, ESKEYMAP, and ISKEYMAP to set the default keymap.
  These options are now gone for good.  The new option is more general.)

2a888f938e Add a prioritization field to the devstat_add_entry() call so that
peripheral drivers can determine where in the devstat(9) list they are
inserted.

This requires recompilation of libdevstat, systat, vmstat, rpc.rstatd, and
any ports that depend on the devstat code, since the size of the devstat
structure has changed.  The devstat version number has been incremented as
well to reflect the change.

This sorts devices in the devstat list in "more interesting" to "less
interesting" order.  So, for instance, da devices are now more important
than floppy drives, and so will appear before floppy drives in the default
output from systat, iostat, vmstat, etc.

The order of devices is, for now, kept in a central table in devicestat.h.
If individual drivers were able to make a meaningful decision on what
priority they should be at attach time, we could consider splitting the
priority information out into the various drivers.  For now, though, they
have no way of knowing that, so it's easier to put them in an easy to find
table.

Also, move the checkversion() call in vmstat(8) to a more logical place.

Thanks to Bruce and David O'Brien for suggestions, for reviewing this, and
for putting up with the long time it has taken me to commit it.  Bruce did
object somewhat to the central priority table (he would rather the
priorities be distributed in each driver), so his objection is duly noted
here.

a6796db6ce Ensure that the i8254 timecounter doesn't go backards. It sometimes
went backwards when interrupts were masked for more than one i8254
interrupt period.  It sometimes went backwards when the i8254 counter
was reprogrammed.  Neither of these should happen in normal operation.

Update the i8254 timecounter support variables atomically.  Calling
timecounter functions from fast interrupt handlers may actually work
in all cases now.

for 1 second's worth of input) and larger tty output buffers.  The
interrupt-level buffers are still too small for speeds above 115200

46f3ff7986 Major ppbus updates from the author.
- ppbus now supports PLIP via the if_plip driver
 - ieee1284 infrastructure added, including parallel-port PnP
 - port microsequencer added, for scripting the sort of port I/O
   that is common with parallel devices without endless calls up and down
   through the driver structure.
 - improved bus ownership behaviour among the ppbus-using drivers.
 - improved I/O chipset feature detection

The vpo driver is now implemented using the microsequencer, leading to
some performance improvements as well as providing an extensive example
of its use.

88a5f0cca7 1. Reorganized screen saver related code so that both the LKM screen
saver and splash screen can all work properly with syscons.  Note that
the splash screen option (SC_SPLASH_SCREEN) does not work yet, as it
requires additional code from msmith.

- Reorganized the splash screen code to match the latest development
  in this area.
- Delay screen switch in `switch_scr()' until the screen saver is
  stopped, if one is running,
- Start the screen saver immediately, if any, when the `saver' key is
  pressed. (There will be another commit for `kbdcontrol' to support
  this keyword in the keymap file.)
- Do not always stop the screen saver when mouse-related ioctls
  are called.  Stop it only if the mouse is moved or buttons are
  clicked; don't stop it if any other mouse ioctls are called.

2. Added provision to write userland screen savers.  (Contact me if you
are interested in writing one.)

- Added CONS_IDLE, CONS_SAVERMODE, and CONS_SAVERSTART ioctls to
  support userland screen savers.

3. Some code clean-ups.

5c1a1eae83 Fixed error handling:
- Call isa_dmadone() whenever necessary to stop DMA and/or free bounce
  buffers.  Undead DMA corrupted the malloc freelist fairly consistently
  in the following configuration: SLICE kernel, 2 floppy drives, no disk
  in fd0, disk in fd1.
- Don't call fdc_reset() from fd_timeout().  Doing so gave an "extra"
  interrupt which was usually misinterpreted as being for completion
  of the next FDC command; the interrupt for completion of the next
  FDC command was then usually misinterpreted...  There were further
  complications for interrupts latched by the soft-spl mechanism so
  that they were delivered after all the h/w interrupts went away.
  This caused at least wrong head settle delays and may be why the
  FreeBSD floppy driver seems to munch floppies more than most floppy
  drivers.  The reset was unnecessary anyway in cases that didn't have
  the bug described next, since is was repeated a little later for
  the IOTIMEDOUT state.  The state machine has complications to handle
  resets correctly, so just use it.
- Don't call retrier() from fd_timeout().  The IOTIMEDOUT state needs
  to be processed next, and it isn't valid to set to that state if
  retrier() has aborted the current transfer.  Doing so caused null
  pointer panics after the previous bug was fixed.

Improved error handling:
- If an i/o is aborted, arrange to reset in the state machine before
  doing the next i/o.  New fdc flag for this.  This fixes spurious
  warnings and lengthy busy-waiting for the next i/o.
- Split STARTRECAL into RESETCOMPLETE and STARTRECAL and only check
  for the results from reset if we actually reset.  This fixes spurious
  warnings for other paths to STARTRECAL.  [Oops, it may break reset
  handling for motor-off resets.]

Cleanups in fd_timeout():
- Renamed to fd_iotimeout() to make it clearer that it is only used
  for i/o.
- Don't handle the bp == 0 case.  This case can't happen for i/o.
- Don't check for controller-busy.  We know it must be.
- Don't print anything.  retrier() already prints too much for normal
  errors.
- Fudge the state differently so that the state machine advances
  fdc->retry and the status is invalid (perhaps this should fudge a
  valid state like the one for WP).
- Style fixes.

e5d7d24361 Fixed error handling after a seek error that can't happen. When the
controller reports a successful seek, it is very unlikely to report
seeking to a cylinder other than the one requested, but we check for
this, and botched the error handling for the requested_cylinder != 0
case.  This error happened when the bug fixed in rev.1.52 of <sys/buf.h>
caused the head of buffer queue to change to one starting on a different
cylnder - the requested cylinder was found, but it wasn't what we
thought we requested.  The fix is simply to arrange to reset the state
machine.

Corruption of the buffer queue seems to only have been a problem in the
floppy driver.  Other drivers dequeue the head of the queue before doing
physical i/o on it, so the corruption at worse broke the elevator sort
order.  Dequeueing breaks it anyway.
