9626b608de Separate the struct bio related stuff out of <sys/buf.h> into
<sys/bio.h>.

<sys/bio.h> is now a prerequisite for <sys/buf.h> but it shall
not be made a nested include according to bdes teachings on the
subject of nested includes.

Diskdrivers and similar stuff below specfs::strategy() should no
longer need to include <sys/buf.> unless they need caching of data.

Still a few bogus uses of struct buf to track down.

3aae7b16d2 Fixed the type of some ivar access functions. Ivars have type uintptr_t,
not u_long.  On i386's with 64-bit longs, returning u_longs indirectly
in (more than) the space reserved for uintptr_t's tended to corrupt the
previous frame pointer in the stack frame, so it was not easy to debug.
The type mismatches are hidden by the bogus cast in DEVMETHOD().

f7b7769172 * Factor out the object system from new-bus so that it can be used by
non-device code.
* Re-implement the method dispatch to improve efficiency. The new system
  takes about 40ns for a method dispatch on a 300Mhz PII which is only
  10ns slower than a direct function call on the same hardware.

This changes the new-bus ABI slightly so make sure you re-compile any
driver modules which you use.

21144e3bf1 Remove B_READ, B_WRITE and B_FREEBUF and replace them with a new
field in struct buf: b_iocmd.  The b_iocmd is enforced to have
exactly one bit set.

B_WRITE was bogusly defined as zero giving rise to obvious coding
mistakes.

Also eliminate the redundant struct buf flag B_CALL, it can just
as efficiently be done by comparing b_iodone to NULL.

Should you get a panic or drop into the debugger, complaining about
"b_iocmd", don't continue.  It is likely to write on your disk
where it should have been reading.

This change is a step in the direction towards a stackable BIO capability.

A lot of this patch were machine generated (Thanks to style(9) compliance!)

5f830ea2cd Make the Y-E Data PCMCIA floppy of the Toshiba Libretto work under
-current.  It doesn't work yet as stable as the 3.x/PAO version of the
driver does, however, i get occasional `FDC direction bit not set' and
other weird messages, but it basically works at least.

The old (defunct) #ifdef FDC_YE stuff has been eliminated completely
now, PCMCIA-FDC specific functions have been implemented differently
where needed.

Unfortunately, due to the fact that the traditional PeeCee FDC with
its funny non-contiguous register space (one register for WD1003
harddisk controllers is interleaved into the FDC register set), and
Peter's subsequent changes involving two different bus space handles
for normal FDCs, the changes required for the Y-E stuff are more
complex than i'd love them to be.  I've done my best to keep the logic
for normal FDCs intact.

Since the Y-E FDC seems to lose interrupts after a FDC reset
sometimes, i've also replaced the timeout logic in fd_turnoff() to
generate an artificial pseudo interrupt in case of a timeout while the
drive has still outstanding transfers waiting.  This avoids the total
starvation of the driver that could be observed with highly damaged
media under 3.x/PAO.  This part of the patch has been revied by bde
previously.

I've fixed a number of occasions where previous commits have been
missing the encapuslation of ISA DMA related functions inside
FDC_NODMA checks.

I've added one call to SET_BCDR() during preparation of the format
floppy operation.  Floppy formatting has been totally broken before in
3.x/PAO (garbage ID fields have been written to the medium, causing
`wrong cylinder' errors upon media reading).  This is just black
magic, i don't have the slightes idea _why_ this needs to be but just
copied over the hack that has been used by the PAO folks in the normal
read/write case anyway.

The entired device_busy() stuff seems to be pointless to me.  In any
case, i had to add device_unbusy() calls symmetrical to the
device_busy() calls, otherwise the PCMCIA floppy driver could never be
deactivated.  (As it used to be, it caused a `mark the device busier
and busier' situation.)  IMHO, all block device drivers should be
marked busy based on active buffers still waiting for the driver, so
the device_unbusy() calls should probably go to biodone().  Only one
other driver (whose name escapes me at the moment) uses device_busy()
calls at all, so i question the value of all this...

I think this entire `device busy' logic simply doesn't fit for PCMCIA
&al.  It cannot be the decision of some piece of kernel software to
declare a device `busy by now, you can't remove it', when the actual
physical power of removing it is the user pulling the card.  The
kernel simply has to cope with the removal, however busy the device
might have been by the time of the removal, period.  Perhaps a force
flag needs to be added?

Upon inserting the card a second time, i get:

WARNING: "fd" is usurping "fd"'s cdevsw[]
WARNING: "fd" is usurping "fd"'s bmaj

I suspect this is related to the XXX comment at the call to
cdevsw_add().  Does anybody know what the correct way is to cleanup
this?

  - IBM ScrollPoint: 2 buttons on top and a stick between the buttons.
    The stick can perform "horizontal scroll" in W*ndows environment.
    The horizontal movement of the stick is detected.  It is currently
    mapped to the Z axis movement in the same way as the first wheel.
    The mouse is recognized as "MouseMan+", as it is considered to be
    a variation of MouseMan.

    of the second wheel is reported as the Z axis movement in the

    Mouse" and "4D+ Mouse".
  - Tweak IntelliMouse support code a bit so that less-than-compatible
    wheel mice can work properly with the psm driver.
- Add driver configuration flags which correspond to the kernel
  options PSM_HOOKRESUME and PSM_RESETAFTERSUSPEND, so that we don't
  need to recompile the kernel when we need these functions.
- Properly keep track of the irq resource.
- Add a watchdog timer in case interrupts are lost (experimental).
- Add `detach' function (experimental).

633f93bee5 Fix crashes on card eject for pccard modems. We check for NULL when
we get the com address.  If so, we go ahead and return.  Bruce thinks
there's a bug in the pccard layer that it terminates devices with
extreme prejustice rather than letting them deside for themselves when
to terminate (and he's likely right).  This fix doesn't change that,
but instead works around it by checking for NULL pointers at more
places than before.

The detach routine still calls functions at interrupt level that
aren't reentrant.  In theory this could cause a problem, but none
showed up in practice.  Future versions should correct this problem,
likely by making the detach process a thread/process at the pccard
level.  NEWCARD will do this, and the current pccard layer should
likely be modified to that as well, should it live long enough.

A few style nits of the same form that were in my original patch sent
off to bde were also fixed as part of this process.  Mostly use of
!ptr and return ENOPARENS.

This should prevent a crash on suspend with an active ppp link as
well, but that wasn't tested.

4f9d49f140 Newbus-ify the USR Sportster TA Intern driver.
Enable the driver in sys/conf/files.i386.

In isa/isavar.h increase ISA_NPORT from 32 to 50. This is required
because this brain-damaged card maps 49 (!) port ranges. This does
not have a negative impact because this value only specifies the maximum
number of entries in a linked list and not the size of an array which
is allocated in all drivers.

The register/fifo access routines were not newbus-ified because
1) I knew that the old code worked and is simpler and more efficient
2) the if_ed driver does something similar and
3) the newbus macros collapse to inb/outb anyway.

34ae9210dd Fixed regressions in rev.1.274:
1) Non-AST4 multiport cards were broken by bypassing the code that changes
   `idev' to the multiport master device.
2) AST4 multiport cards apparently were broken by inverting the test for
   the master device having an irq.
3) Error handling for nonexistent master devices was broken by removing a
   check for a null pointer.
4) `int' error codes returned by bus_get_resource() were assigned directly
   to the boolean variable com->no_irq.  Probably harmless, since the
   boolean is implemented as a u_char.

208cc52f94 When allocating resources in the following cases:
- trying for a fit for a PnP configuration from a device
 - soaking up resources from a configuration that were not allocated by
   the driver

do not attempt to activate them.  Only a device driver that is aware of
the nature of the resource and its suitability can be certain that
activating a resource, particularly a memory resource, is a safe thing
to do.

This was prompted by the discovery that many systems report all physical
memory through a PNP0c02 device; activating this resource maps all
physical memory into the kernel's virtual space, either blowing out the
kernel pagetable or in the worst case causing a panic in pmap_mapdev()
if the system has too much physical memory.

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.

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.

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).

Also, if a BUS_SETUP_INTR() fails with INTR_TYPE_FAST, try falling back to

fe0d408987 Remove the 'ivars' arguement to device_add_child() and

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

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.

o ed driver changes

9dcbe2404a Convert DEVFS hooks in (most) drivers to make_dev().
Diskslice/label code not yet handled.

Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)

Add the correct hook for devfs to kern_conf.c

The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.

A few drivers had minor additional cleanups performed relating to cdevsw
registration.

A few drivers don't register a cdevsw{} anymore, but only use make_dev().

800da3b22a - Remove cdevsw entry points in individual keyboard drivers;
instead, use generic entry points for all drivers.
- Eliminate bogus makedev().
- Eliminate softc in the lower drivers, as it is no longer necessary.

086646f7c6 Properly set the alignment argument to bus_dma_tag_create(). If we
don't care about the alignment, set it to 1, meaning single byte alignment.

49ff4debd3 Spring cleaning around strategy and disklabels/slices:
Introduce BUF_STRATEGY(struct buf *, int flag) macro, and use it throughout.
please see comment in sys/conf.h about the flag argument.

Remove strategy argument from all the diskslice/label/bad144
implementations, it should be found from the dev_t.

Remove bogus and unused strategy1 routines.

Remove open/close arguments from dssize().  Pick them up from dev_t.

Remove unused and unfinished setgeom support from diskslice/label/bad144 code.

15317dd875 Alter the behavior of sys/kern/subr_bus.c:device_print_child()
- device_print_child() either lets the BUS_PRINT_CHILD
	  method produce the entire device announcement message or
	  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()
	- All BUS_PRINT_CHILD methods return the number of
	  characters output.

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
timer.

409aadb1c9 Hack to work around a NULL pointer dereferencation that can be triggered
by removing a floppy that as being operated on.

The spagghetti is hardly understandable at all anymore, so i can't
100 % ascertain this is really the Right Thing to do, maybe our new
floppy driver maintainer, Jesus Monroy Jr can do this. :-))

ab64b6dc3c Don't let the machdep.tsc_freq sysctl proceed if the TSC is present
but broken, since tsc_timecounter is not initialised in that case,
and updating an uninitialised timecounter is fatal.

Fixed style bugs in the machdep.i8254_freq and machdep.tsc_freq
sysctls.

67812eacd7 Convert buffer locking from using the B_BUSY and B_WANTED flags to using
lockmgr locks. This commit should be functionally equivalent to the old
semantics. That is, all buffer locking is done with LK_EXCLUSIVE
requests. Changes to take advantage of LK_SHARED and LK_RECURSIVE will
be done in future commits.
