6c56727456 - Change fast interrupts on x86 to push a full interrupt frame and to
return through doreti to handle ast's.  This is necessary for the
  clock interrupts to work properly.
- Change the clock interrupts on the x86 to be fast instead of threaded.
  This is needed because both hardclock() and statclock() need to run in
  the context of the current process, not in a separate thread context.
- Kill the prevproc hack as it is no longer needed.
- We really need Giant when we call psignal(), but we don't want to block
  during the clock interrupt.  Instead, use two p_flag's in the proc struct
  to mark the current process as having a pending SIGVTALRM or a SIGPROF
  and let them be delivered during ast() when hardclock() has finished
  running.
- Remove CLKF_BASEPRI, which was #ifdef'd out on the x86 anyways.  It was
  broken on the x86 if it was turned on since cpl is gone.  It's only use
  was to bogusly run softclock() directly during hardclock() rather than
  scheduling an SWI.
- Remove the COM_LOCK simplelock and replace it with a clock_lock spin
  mutex.  Since the spin mutex already handles disabling/restoring
  interrupts appropriately, this also lets us axe all the *_intr() fu.
- Back out the hacks in the APIC_IO x86 cpu_initclocks() code to use
  temporary fast interrupts for the APIC trial.
- Add two new process flags P_ALRMPEND and P_PROFPEND to mark the pending
  signals in hardclock() that are to be delivered in ast().

1931cf940a - Heavyweight interrupt threads on the alpha for device I/O interrupts.
- Make softinterrupts (SWI's) almost completely MI, and divorce them
  completely from the x86 hardware interrupt code.
  - The ihandlers array is now gone.  Instead, there is a MI shandlers array
    that just contains SWI handlers.
  - Most of the former machine/ipl.h files have moved to a new sys/ipl.h.
- Stub out all the spl*() functions on all architectures.

9a94c9c5c3 - Remove the inthand2_t type and use the equivalent driver_intr_t type from
newbus for referencing device interrupt handlers.
- Move the 'struct intrec' type which describes interrupt sources into
  sys/interrupt.h instead of making it just be a x86 structure.
- Don't create 'ithd' and 'intrec' typedefs, instead, just use 'struct ithd'
  and 'struct intrec'
- Move the code to translate new-bus interrupt flags into an interrupt thread
  priority out of the x86 nexus code and into a MI ithread_priority()
  function in sys/kern/kern_intr.c.
- Remove now-uneeded x86-specific headers from sys/dev/ata/ata-all.c and
  sys/pci/pci_compat.c.

a0e1678488 Add a nasty hack to get remote kernel gdb working from ddb. ddb would
complain before that a suitable gdb port had not been setup because gdbdev
was NULL.  This abuses the fact that the gdb port is hard-coded to the
address normally assigned to sio1 and thus hard-codes in sio1 as the gdb
port.  Yuck.

0384fff8c5 Major update to the way synchronization is done in the kernel. Highlights
include:

* Mutual exclusion is used instead of spl*().  See mutex(9).  (Note: The
  alpha port is still in transition and currently uses both.)

* Per-CPU idle processes.

* Interrupts are run in their own separate kernel threads and can be
  preempted (i386 only).

db90128160 Avoid the modules madness I inadvertently introduced by making the
cloning infrastructure standard in kern_conf.  Modules are now
the same with or without devfs support.

If you need to detect if devfs is present, in modules or elsewhere,
check the integer variable "devfs_present".

This happily removes an ugly hack from kern/vfs_conf.c.

This forces a rename of the eventhandler and the standard clone
helper function.

Include <sys/eventhandler.h> in <sys/conf.h>: it's a helper #include
like <sys/queue.h>

Remove all #includes of opt_devfs.h they no longer matter.

21c3015a24 * Completely rewrite the alpha busspace to hide the implementation from
the drivers.
* Remove legacy inx/outx support from chipset and replace with macros
  which call busspace.
* Rework pci config accesses to route through the pcib device instead of
  calling a MD function directly.

With these changes it is possible to cleanly support machines which have
more than one independantly numbered PCI busses. As a bonus, the new
busspace implementation should be measurably faster than the old one.

2b2b44c983 Don't assume that any ISA device that fails to probe is a PnP device,
instead, use the bus_print_child_* functions to display the error message.
Also, since this is more of a warning than an error, hide it behind
bootverbose.

Similarly, if isa_assign_resources() fails to allocate resources to a
device, use bus_print_child_header() instead of device_printf(), and
display the resources that could not be allocated if bootverbose is true.

2a50a6d730 Add PnP probe methods to some common AT hardware drivers. In each case,

somewhat.

81e3fd99fc This is a temporary bandaid to get vidconsole working again without
options USERCONFIG being present.  Due to the lack of early boot hints
neither sio or sc would succeed the console probe.  If USERCONFIG was
active, there was a second cninit() after userconfig had run and that
happened to make the console selection work.  If you left out USERCONFIG,
you would end up with no console at all. :-(

This needs a proper fix, especially when sc looses the "at isa" hint.
But for now, this works.

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.

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?

  - 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.

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).
