even if PCI and the IDs are right), just for sanity, before declaring
success. Split the single 0x3b0 -> 0x3df allocation into three seperate
ones: 0x3b0 -> 0x3bc (leaving the 4 ports available for lpt),
0x3c0 -> 0x3cf, and 0x3d0 -> 0x3df. The former chunk has to be split
off if the lpt can exist there, and it's sort-of pretty to have each
group (based on second hex digit) have its own handle.
These alternative macros have a workaround for the STM^ bug in revision < 3
StrongARM CPU's that causes incorrect register saving if a cache line fill
is in progress during the STM.
a podulebus.
Make sure the podulebus driver conforms to the Acorn expansion card
specification:
- Probe the podule bus using sync access cycles rather than slow access
cycles.
- Read the podulebus header/ROM using sync access cycles rather than slow
access cycles
of targets attached and access those simultaneously (like in a ccd(4) array).
We (now) allocate (somewhat arbitrarily) three per target.
Noticed by Marshall Midden.
1. fix possible hang in en_txlaunch(). when attempting to extend
the length of an mbuf to avoid a flush we should extend it
by cnt [which is ((need - len) % 4)] rather than 4 - cnt.
also, add an EN_DEBUG printf() when we pad/FLUSH a buffer
to help with debugging/understanding what the driver is up to.
2. use interface packet counters
3. when turning off a recv VCI we recompute the new mode. make sure
we don't include the "in service" bit in the new mode, otherwise
a VCI may appear "hung" if you turn it off while a service
interrupt is pending.
4. when shutting down a VCI that is still receiving data, don't bother
going into "drain mode" if only the hardware in service bit is
set (otherwise the VCI may get "hung" in drain mode).
as a result of this we may get "unexpected rx interrupt" messages
which are not really an error, so put this printf in EN_DEBUG.
5. be sure to zero txspeed[lcv] when enabling a VCI (start at full
speed). (hooks for setting txspeed[] are currently not in
the driver, but we are playing with it locally).

If not compiled with -D_KERNEL, include different includes and
do so macro magic so that this will fit sanely into test harnesses.
When used in user-land, this should be compiled with -D_EXTENT_TESTING.
Bug fixes:
(extent_insert_and_optimize) You can't do things like:
LIST_REMOVE(elem->...le_next, ...);
free(elem->...le_next, ...);
They just don't work (and will corrupt your list and/or malloc free list).
(extent_alloc_region_descriptor) Unless you wait, malloc can fail.
Don't accidentally deref a potentially-NULL pointer.
-o (the reverse of this, also the default)
- use vis(3) in vputc() instead of handcrufted function (from OpenBSD).
- move gecos expansion into expandusername() (a la sendmail's buildfname).
A generic version of this last bit in libutil would be useful...
- cleanup the code, fix prototypes, etc.
2841, plus some fixes to make the patches work on the Alpha. Seems to
improve the NCR driver a lot. We probably should try to incorporate
any updates that have happened since, too.
Interrupts for irqs with handlers are counted as normal, even if none of
the handlers claim the interrupt.
Should all be redone with hierarchical event counters. that count
hardware events and invocations of each handler separately.
* Increment cnt.v_intr for normal interrupts (bugfix).

to initialize conspa was invalid on non-040 machines, since we don't
know which MMU we're using on those, yet. On the other hand, by the time
we get to check_video() on the 040 machines, the MMU has been disabled.
Compromise: get the video PA in setmachdep() on the 040, and in
check_video() on the others. (This is not optimal. *sigh*)
ioctl and mmap routines take a void *, rather than a struct device *,
so that they can be set up to work more easily when using a 'struct device *'
isn't appropriate. Add a cookie (void *) to be passed to the mmap and
ioctl routines. Rename a few struct members, and shuffle them into
a more sensible order.
