- Convert to new bus attachment scheme. Thanks to Blaz Zupan for doing
the initial work here. One thing I changed was to have the attach
and detach routines work like the PCI drivers, which means that in
theory you should be able to load and unload the driver like the PCI
NIC drivers, however the pccard support for this hasn't settled down
yet so it doesn't quite work. Once the pccard work is done, I'll have
to revisit this.
- Add device wi0 to PCCARD. If we're lucky, people should be able to
install via their WaveLAN cards now.
- Add support for signal strength caching. The wicontrol utility has
also been updated to allow zeroing and displaying the signal strength
cache.
- Add a /sys/modules/wi directory and fix a Makefile to builf if_wi.ko.
Currently this module is only built for the i386 platform, though once
the pccard stuff is done it should be able to work on the alpha too.
(Theoretically you should be able to plug one of the WaveLAN/IEEE ISA
cards into an alpha with an ISA slot, but we'll see how that turns out.
- Update LINT to use only device wi0. There is no true ISA version of
the WaveLAN/IEEE so we'll never use an ISA attachment.
- Update files.i386 so that if_wi is dependent on card.
to use a locked cmpexg when unlocking a lock that we already hold, since
nobody else can touch the lock while we hold it. Second, it is not
necessary to use a locked cmpexg when locking a lock that we already
hold, for the same reason. These changes will allow MP locks to be used
recursively without impacting performance.
Modify two procedures that are called only by assembly and are already
NOPROF entries to pass a critical argument in %edx instead of on the
stack, removing a significant amount of code from the critical path
as a consequence.

the countdown register.
this should not be necessary but there are broken laptops that
do not restore the countdown register on resume.
when it happnes, it messes up the hardclock interval and system clock,
which leads to the infamous "calcru: negative time" problem.

Merge the contents (less some trivial bordering the silly comments)
of <vm/vm_prot.h> and <vm/vm_inherit.h> into <vm/vm.h>. This puts
the #defines for the vm_inherit_t and vm_prot_t types next to their
typedefs.
This paves the road for the commit to follow shortly: change
useracc() to use VM_PROT_{READ|WRITE} rather than B_{READ|WRITE}
as argument.
Note to self; when converting a driver to newbus, the foodriver bits
must be removed from sys/i386/isa/isa_compat.h

if_fe.c uses PCCARD_MODULE() and is part of GENERIC. I've #ifdef'ed out
the #include of "card.h" to hopefully disable pccard support in this
driver until it can be converted. I'm not positive this will fix make
release, but it can't possibly make it any worse than it is now.
I hope this stuff settles down soon.
Been in production for 3 years now. Gives Instant Frame relay to if_sr
and if_ar drivers, and PPPOE support soon. See:

- PnP now supported.
Will convert to bus_space, ifmedia and add a DEVICE_IDENTIFY() method
for autodetection. As it stands
device ex0 at isa0
should find a card if one is present.
I feel less dirty now.

* Move set_resource, get_resource and delete_resource from
isa_if.m to bus_if.m.
* Simplify driver code by providing wrappers to those methods:
bus_set_resource(dev, type, rid, start, count);
bus_get_resource(dev, type, rid, startp, countp);
bus_get_resource_start(dev, type, rid);
bus_get_resource_count(dev, type, rid);
bus_delete_resource(dev, type, rid);
* Delete isa_get_rsrc and use bus_get_resource_start instead.
* Fix a stupid typo in isa_alloc_resource reported by Takahashi
Yoshihiro <nyan@FreeBSD.org>.
* Print a diagnostic message if we can't assign resources to a PnP
device.
* Change device_print_prettyname() so that it doesn't print
"(no driver assigned)-1" for anonymous devices.
- Move intrhook stuff into kernel.h
- Remove all occurrences of #device <device.h>
- Add kernel.h were necessary (nowhere)
- delete device.h
This file contained the structures for cfdata (old style config) and is no
longer used. It was included by most drivers.
It confuses the remote debugger as the definition of 'struct device' in
device.h is found before the one in bus_private.h.
Turn on the 'new' if_ep driver which supports:
ISA 3c509
MCA 3c529
EISA 3c579
PCCARD 3c589
I think all we're missing is support for the VME bus and S-100 bus
Etherlink III cards.
The new code has been tested by a number of people and all the important
bits work. I've not been able to test the EISA code but will do so once
my hardware arrives. Since I've changed nothing in the EISA code I suspect
it will perform the same manner as before.
Future changes involve whacking the ISA and PCCARD front ends to use
newbus and to convert the driver to bus_space and make it use ifmedia.
This is the first working network driver that supports MCA bus devices btw.
Enjoy.
work. Be more verbose when one cannot allocate IRQ, et al since this
is a common configuration problem. The cards have the IRQ soft wired
into their BIOS and do not try to do collision detection. This can
cause problems when this IRQ is the same as another card/device.
The PNP hasn't been tested. My PNP board is in a deployed system.
I'll sneak in testing of it sometime later. I've been able to mount
the 3.3R cdrom that arrived today and access files off it.
