being used without ever being initialized. From examining
the rest of the routine, it looks like this is a typo,
and it really should have been "1" instead of "i".

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.

All new code is "#ifdef PC98"ed so this should make no difference to
PC/AT (and its clones) users.

in place device drivers can now register power-down/power-up routines so
that we can use common routines to power-up/power-down cards for
insert/removals, suspend/resume, etc..

#include <i386/include/clock.h> to get sysbeep() prototype
pcic.c:
add appropriate #ifdef around a prototype to quiet GCC because
fn decl. is also #ifdef'd.
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)
seems to work here..
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...
If you want to add a new device in conf.c
please make sure I know
so I can keep it up to date too..
as before, this is all dependent on #if defined(JREMOD)
(and #ifdef DEVFS in parts)
to <machine/conf.h>. conf.h was mechanically generated by
`grep ^d_ conf.c >conf.h'. This accounts for part of its ugliness. The
prototypes should be moved back to the driver sources when the functions
are staticalized.
This is still very green, but I have managed to get my modem working.
Lots of work still to do, but now at least we can commit it. /phk
