586079cc26 Don't include <isa/isavar.h> or compile code depending on it when isa
is not configured.  Including <isa/isavar.h> when it is not used is
harmful as well as bogus, since it includes "isa_if.h" which is not
generated when isa is not configured.

This was fixed in 1999 but was broken by unconditionalizing PNPBIOS.

98f9879242 Introduce a standard name for the lock protecting an interrupt controller
and it's associated state variables: icu_lock with the name "icu".  This
renames the imen_mtx for x86 SMP, but also uses the lock to protect
access to the 8259 PIC on x86 UP.  This also adds an appropriate lock to
the various Alpha chipsets which fixes problems with Alpha SMP machines
dropping interrupts with an SMP kernel.

038d1bbd1a Change the test for _MACHINE_ARCH == i386 into #ifdef __i386__ since it
otherwise breaks on the Alpha arch.  I think this is wrong since i'd
actually like to probe for a PC architecture, not for a particular CPU
type.  Anyway, now it's again the way it used to be.

1a6bed6863 Long promised major enhancement set for the floppy disk driver:
. The main device node now supports automatic density selection for
  commonly used media densities.  So you can stuff your 1.44 MB and
  720 KB media into your drive and just access /dev/fd0, no questions
  asked.  It's all that easy, isn't it? :)

. Device density handling has been completely overhauled.  The old way
  of hardwired kernel density knowledge is no longer there.  Instead,
  the kernel now implements 16 subdevices per drive.  The first
  subdevice uses automatic density selection, while the remaining 15
  devices are freely programmable.  They can be assigned an arbitrary
  name of the form /dev/fd[:digit]+.[:digit:]{1,4}, where the second
  number is meant to either implement device names that are mnemonic
  for their raw capacity (as it used to be), or they can alternatively
  be created as "anonymous" devices like fd0.1 through fd0.15,
  depending on the taste of the administrator.  After creating a
  subdevice, it is initialized to the maximal native density of the
  respective drive type, so it needs to be customized for other
  densities by using fdcontrol(8).  Pseudo-partition devices (fd0a
  through fd0h) are still supported as symlinks.

. The old hack to use flags 0x1 to always assume drive 0 were there is
  no longer supported; this is now supposed to be done by wiring the
  devices down from the loader via device flags.  On IA32
  architectures, the first two drives are looked up in the CMOS
  configuration records though.  On PCMCIA (i. e., the Y-E Data
  controller of the Toshiba Libretto), a single drive is always
  assumed.

. Other specialities like disabling the FIFO and not probing the drive
  at boot-time are selected by per-controller or per-drive flags, too.

. Unit attentions (media has been changed) are supposed to be detected
  now; density autoselection only occurs after a unit attention.  (Can
  be turned off by a per-drive flag, this will cause each Fdopen() to
  perform the autoselection.)

. FM floppies can be handled now (on controllers that actually support
  it -- not all do these days).

. Fdopen() can be told to avoid density selection by setting
  O_NONBLOCK; this leaves the descriptor in a half-opened state where
  only a few ioctls are accepted.  This is necessary to run fdformat
  on a device that uses automatic density selection (since you cannot
  autoselect on an unformatted medium, obviously).

. Just differentiate between a plain old NE765 and the enhanced chips,
  but don't try more; the existing code was wrong and only misdetected
  the chips anyway.

BUGS and TODOs:

. All documentation update still needs to be done.

. Formatting not-so-standard format yields unpredictable results; i
  have yet to figure out why this happens.  "Standard" formats like
  720 and 1440 KB do work, however.

. rc scripts are needed to setup device nodes with nonstandard
  densities (like the old /dev/fdN.MMM we used to have).

. Obtaining device flags from the kernel environment doesn't work yet,
  thus currently only drives that are present in (IA32) CMOS are
  really detected.  Someone who knows the odds and ends about device
  flags is needed here, i can't figure out what i'm doing wrong.

. 2.88 MB still needs to be done.

f9390180fe Some fix for the recent apm module changes.
- Now that apm loadable module can inform its existence to other kernel
   components  (e.g. i386/isa/clock.c:startrtclock()'s TCS hack).
 - Exchange priority of SI_SUB_CPU and SI_SUB_KLD for above purpose.
 - Add simple arbitration mechanism for APM vs. ACPI.  This prevents
   the kernel enables both of them.
 - Remove obsolete `#ifdef DEV_APM' related code.
 - Add abstracted interface for Powermanagement operations.  Public apm(4)
   functions, such as apm_suspend(), should be replaced new interfaces.
   Currently only power_pm_suspend (successor of apm_suspend) is implemented.

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"

d117cb4e19 Handle "identifier strings" right. Each ISA PnP card must have a
mandatory "card" identifier string.  A logical devices on the ISA PnP
card may optionally have a "device" identifier string. Do not confuse
them.

The "card" identifier string is assigned to a logical device as the
default description string when the device is found. (If the "card"
identifier string has not been found, use the EISA PnP ID string.
Strictly speaking, this is an error.)  We will override it when a
"device" identifier string is found later.

  multi-line form, make them sentences where apprpriate, etc.

. Declare all functions on top, and declare them in the order they
  appear in the file.  This order is totally chaotic, but Bruce
  convinced me that reordering the file wouldn't make it better either.

. Kill a `possibly uninitialized' warning (only seen with -O2) in
  fd_read_status().

. Make the comments at return (0|1) statements in fdstate() consistent.

. Nuke a ``keep the compiler happy'' dummy return at the end of fdstate(),

fb35bd37f2 Another large patchset from Bruce.
Despite of a few cosmetic things like adding ``irritating silly
parentheses'' around all return values, this mainly improves FDC reset
handling by no longer gratuitously resetting the FDC all the time
(which causes it to lose the notion of the current track) but only in
case of errors, and it sanitizes the block and offset calculations in
fdstrategy() and fdstate().  Some additional cleanup added by me, in
particular the large switch in fdstate() now always uses return to
break out, and no branch falls off the end of the switch statement
anymore.  Per Bruce's suggestion, removed M_NOWAIT from the malloc()s
to simplify things.

6044485346 More cleanup when detaching. Clone device entries will now be
destroyed properly (otherwise bad things would happen after a clone
dev had been created, and the module was kldunloaded).  Allocated
children that have not successfully probed are being deleted again
(otherwise fd0 and fd1 have always been allocated, even if only
fd0 was acutally present, and fd1 even survived kldunloading the
module).

Still, kldunloading leaves remnants of the previously existing devices
intact.  Why doesn't it destroy all the devices?  As a consequence,
since dev->descr now points into no longer allocated memory, the
system panics deep inside printf(9) when running devinfo(1) after
kldunloading the module.  Ideas sought...

Also, when kldloading the module on a hints-populated isab0, this bus
somehow has already created an fdc0 entry (a dummy) so the load
attempt fails and will register fdc1 instead.  What are those dummy
entries for?  Loading the module from the bootloader works, and it
can be unloaded an re-loaded then later.
