have bad grounding characteristics which allow small static discharges
(or sunspots, we're not 100% sure which) to reach the bridge chip.
This causes the bridge chip to wedge/reset itself. There's no known
cure short of rebooting.
The bug manifests itself by the STAT_CHG return 0xff when read. This
is impossible because the upper bits are reserved (and therefore
zero). In addition, some of the lower bits are one only for memory
cards, which OLDCARD doesn't support, so if they are set, something
seriously foobar'd is going on.
So far we've seen this in exactly one brand of pcmcia <-> isa bridge
which plug and play identifies only as "VIA PCMCIA CARD". This card
just has buffers on the isa card and the actual bridge chip on the
remote slot, which is connected by long ribbon cables. We think this
long cable run, coupled with the lack of coupling capacitors is a
major reason why it is so static sensitive while its bretheren aren't.

attached to the pccard bus and thus fails to call device_delete_child()
on them. The end result is that when a card is removed, its detach
routine is never called, and re-insertion always fails.

abuses its argument, which is supposed to be an integer unit number, as
a pointer to the head of the 'struct slot' list. When this code was
hacked^Wupdated for newbus, a new mechanism for registering slot_irq_handler()
was put in place and the significance of the unit number was overlooked.
When registering an interrupt, we have both device_id and unit. The unit
number is passed as 'unit' but /sys/i386/usa/intr_machdep.c:register_intr()
drops unit on the floor and uses device_id instead. Since pccard_alloc_intr()
always sets device_id to 0, this means the unit number is always zero, and
slot_irq_handler() is always called with 0, which becomes a NULL pointer
which slot_irq_handler() tries to dereference and the kernel explodes.
Result: if you assign a PCMCIA driver in the kernel config file like this:
device wi0 at isa? port? irq?
Then the system will panic the moment a PCMCIA device is attached and
an interrupt is triggered.
The quick fix: make pccard_alloc_intr() pass the unit number as both
the device_id and unit arguments to register_pcic_intr(). The correct fix
would be to rewrite /sys/pccard to be less disgusting.

already.

The only reason the drivers are still on the list is because of race
conditions where the card is removed while the driver is in use. We
leave the drivers on the slot list (leaving all of their structures in
place in case a process is using it) but set it's state to empty so that
further uses by the pccard code know not to expect active cards.

2. pccard.c: PCIC_RESUME_RESET is now (also) a sysctl. (Never make it
a #ifdef if it can be made a sysctl!)

pcic_slot. Add a couple of missing casts.
Use the name argument almost the same in all LKM types. Maintain
the current behavior for the external (e.g., modstat) name for DEV,
EXEC, and MISC types being #name ## "_mod" and SYCALL and VFS only
#name. This is a candidate for change and I vote just the name without
the "_mod".
Change the DISPATCH macro to MOD_DISPATCH for consistency with the
other macros.
Add an LKM_ANON #define to eliminate the magic -1 and associated
signed/unsigned warnings.
Add MOD_PRIVATE to support wcd.c's poking around in the lkm structure.

Assuming that the intr_mask[] was updated by changing the maskptrs (the
existing update_intr_masks() function will not work) this code was
written so the PCIC controller insertion/removal events will not
interrupt the card IRQ handler events.
Some possible scenarios:
+ Card is removed during IRQ handler:
- PCIC card handler is allowed to interrupt
- card removal event is called, removing the driver and data structures
* card interrupt handler continues w/out driver, data structures, and hardware
OR (the code just committed)
* card IRQ handler has no hardware to read/write to, but has code and
data to run on (XXX- Assume it completes and doesn't spin forever)
- PCIC card handler unloads the card driver
The current situation at least leaves the card interrupt handlers the
drivers and data structures to work with although the hardware can't be
guaranteed.

- don't include <sys/ioctl.h> in any header. Include <sys/ioccom.h>
instead. This was already done in 4.4Lite for the most important
ioctl headers. Header spam currently increases kernel build
times by 10-20%. There are more than 30000 #includes (not counting
duplicates) for compiling LINT.
- include <sys/types.h> if and only it is necessary to make the header
almost self-sufficient (some ioctl headers still need structs from
elsewhere).
- uniformized idempotency ifdefs. Copied the style in the 4.4Lite
ioctl headers.
All new code is "#ifdef PC98"ed so this should make no difference to
PC/AT (and its clones) users.

most devsw referenced functions are now static, as they are
in the same file as their devsw structure. I've also added DEVFS
support for nearly every device in the system, however
many of the devices have 'incorrect' names under DEVFS
because I couldn't quickly work out the correct naming conventions.
(but devfs won't be coming on line for a month or so anyhow so that doesn't
matter)
If you "OWN" a device which would normally have an entry in /dev
then search for the devfs_add_devsw() entries and munge to make them right..
check out similar devices to see what I might have done in them in you
can't see what's going on..
for a laugh compare conf.c conf.h defore and after... :)
I have not doen DEVFS entries for any DISKSLICE devices yet as that will be
a much more complicated job.. (pass 5 :)
pass 4 will be to make the devsw tables of type (cdevsw * )
rather than (cdevsw)

complaints to the usual places.. :)
That's EVERY SINGLE driver that has an entry in conf.c..
my next trick will be to define cdevsw[] and bdevsw[]
as empty arrays and remove all those DAMNED defines as well..
Each of these drivers has a SYSINIT linker set entry
that comes in very early.. and asks teh driver to add it's own
entry to the two devsw[] tables.
some slight reworking of the commits from yesterday (added the SYSINIT
stuff and some usually wrong but token DEVFS entries to all these
devices.
BTW does anyone know where the 'ata' entries in conf.c actually reside?
seems we don't actually have a 'ataopen() etc...

please make sure I know
so I can keep it up to date too..
