60767a2384 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.

27235775e1 Add option ALT_BREAK_TO_DEBUGGER.
Implement the Solaris way to break into DDB over a serial console
instead of sending a break.  Sending the character sequence
CR ~ ^b will break the kernel into DDB (if DDB is enabled).

more frequently than the core part of the sio driver, it might
be good to move the PnP IDs to sio_isapnp.h or something like
that.

2c5c997046 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().

a246e10f55 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!)

5ca5ef9503 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?

b91cbcb4f1 - Add Support for the following PS/2 mice:

  - 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.
  - A4 Tech 4D and 4D+ mice. These mice have two wheels! The movement
    of the second wheel is reported as the Z axis movement in the
    same way as the first wheel. These mice are recognized as "4D
    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).

036c5aaf83 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.

75e6ea817c 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.

2) AST4 multiport cards apparently were broken by inverting the test for

3) Error handling for nonexistent master devices was broken by removing a

4) `int' error codes returned by bus_get_resource() were assigned directly

59c87d6c95 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.
