o Add signed/unsigned functionality to the matrox meteor device driver.
o Apply a few fixes to the sound driver.
o Add a ``SPIGOT_UNSECURE'' compile time definition so, if one defines
SPIGOT_UNSECURE in their conf file, then they can use the spigot w/o
root. There is a warning that this allows users access to the IO
page which is probably not secure.

totally dynamic. (the first was about 7 weeeks ago)
this is only the devices in i386/isa
I'll do more tomorrow.
they're completely masked by #ifdef JREMOD at this stage...
the eventual aim is that every driver will do a SYSINIT
at startup BEFORE the probes, which will effectively
link it into the devsw tables etc.
If I'd thought about it more I'd have put that in in this set (damn)
The ioconf lines generated by config will also end up in the
device's own scope as well, so ioconf.c will eventually be gutted
the SYSINIT call to the driver will include a phase where the
driver links it's ioconf line into a chain of such. when this phase is done
then the user can modify them with the boot: -c
config menu if he wants, just like now..
config will put the config lines out in the .h file
(e.g. in aha.h will be the addresses for the aha driver to look.)
as I said this is a very small first step..
the aim of THIS set of edits is to not have to edit conf.c at all when
adding a new device.. the tabe will be a simple skeleton..
when this is done, it will allow other changes to be made,
all teh time still having a fully working kernel tree,
but the logical outcome is the complete REMOVAL of the devsw tables.
By the end of this, linked in drivers will be exactly the same as
run-time loaded drivers, except they JUST HAPPEN to already be linked
and present at startup..
the SYSINIT calls will be the equivalent of the "init" call
made to a newly loaded driver in every respect.
For this edit,
each of the files has the following code inserted into it:
obviously, tailored to suit..

self-decompressing ram disk that I'm fiddling with..
(Note, this depends on the various syscalls having correctly set uio_segflag
before calling physio - I've checked and they look correct.)
What was happening, was that the main mfs loop was sleeping, and when it was
being awoken by a wakeup when it was supposed to process some IO requests.
The problem was that if it was being woken out of the tsleep() by a signal
at shutdown, it was going straight into dounmount() without servicing any
pending IO requests, causing dounmount() to fail because there were busy
buffers (and they could not be "processed" because the processing loop was
trying to unmount rather than dispatching into mfs_doio()).
This (dare I say it :-) appears to be a layering problem....
to get the prototypes.
Changed some `int's to `boolean_t's. boolean_t's are ints so they are
hard to distinguish from ints.
Converted function headers to old-style. ddb is written in K&R1 C
except where we broke it.
- don't #include other headers just to get struct names.
- don't use __BEGIN_DECLS/__END_DECLS for system prototypes. It is for
user prototypes.
- don't use extern.
- don't use lines longer than 80 columns.
- use alphabetical order.
- use tabs.
Uniformized idempotency ifdefs.
it `const' to inhibit compiler warnings.
Added #include of <pccard/driver.h> to get prototypes. <pccard/slot.h>
is still necessary for its side effect of exporting non-slot things.
HD64570 chip. Both the 2 and 4 port cards is supported and auto detected.
Line speeds of up to 2Mbps is possible. At this speed about 85% of the
bandwidth is usable with 486DX processors.
The standard FreeBSD sppp code is used for the link level layer. The
default protocol used is PPP. The Cisco HDLC protocol can be used by
adding "link2" to the ifconfig line in /etc/sysconfig or where ever
ifconfig is run.
At the moment only the V.35 and X.21 interfaces is supported. The others
may need tweaks to the clock selection code.

is acknowledged, it should go to the lcp ack sent state.
Don't reply on lcp echo requests when not in the lcp opened state.
If the interface is set to CISCO mode, it should still be marked
running when ifconfiged.
Fixed a few indentations that had gone wrong somewhere.

bit set. I broke stat_imask in Dec 1994 and update_intr_masks() has
copied the breakage to intr_mask[8] since Mar 1995. This can cause
the RTC to stop interrupting in rare cases (under loads heavy enough
for a new RTC interrupt to occur at a critical time just before Xintr8
finishes handling the previous one) and may have caused worse problems.
Convert the remaining sysctl stuff to the new way of doing things.
the devconf stuff is the reason for the large number of files.
Cleaned up some compiler warnings while I were there.
