Virgin import of Xircom PCCARD driver v1.17
v1.17 (1999/03/28) has xperimental fixes to 10Mbit autonegotiation and
CE2 input lockup.
KNOWN BUGS
==========
* Media auto-negotiation is definitely not right. It will work in most
circumstances and seems to connect OK to most 100Mbit networks, however some
pathological combinations of hubs/networks/peers seem to confuse it.
* CE2 support is somewhat flakey (ranging from 'works perfectly' to 'hangs the
machine' so far). I've fixed the probe routine and a potential lockup in
the output routine, but a lot of people still report that they can't receive
or transmit.
* You won't be able to use the modem and Ethenet parts of a multifunction card
simultaneously. This is limitation the current FreeBSD PCMCIA support.
Likewise, there is no support for CardBus devices.

Previously directories were sync'ed every 10 seconds while bitmaps &
inodes were synced every 15 seconds. This is now reversed as during
directory create, we cannot commit the directory entry until its
inode has been written. With this switch, the inodes will be more
likely to be written by the time that the directory is written thus
reducing the number of directory rollbacks that are needed.
Kirk McKusick [Fri, 14 May 1999 01:26:46 +0000 (01:26 +0000)]
Add a hook to ffs_fsync to allow soft updates to get first chance at doing
a sync on the block device for the filesystem. That allows it to push the
bitmap blocks before the inode blocks which greatly reduces the number of
inode rollbacks that need to be done.

Remove unneeded line of code that got left behind when I converted this
driver to use bus_space_read_foo()/bus_space_write_foo(). The line is not
visible unless you compile the driver to use PCI memory mapped mode, which
not done by default, but it should be fixed anyway.

Fixed 10 out of 40 lines of -Wcast-qual warnings/errors. 3 lines were
for old confusion of `volatile char *' with `volatile caddr_t'. 7 lines
were for not being careful about aligning pointers to volatiles.

Fixed nonsense arg type `const caddr_t' in the prototype() for utrace().
Changed to `const void *'. utrace() is undocumented, so nothing should
notice.
Fixed missing consts for utrace() and ktrace() in syscalls.master.
sys/ktrace.h is missing some Lite2 changes of shorts to ints.

memcmp -> bcmp. memcmp doesn't exist in the kernel, but unfortunately
it exists as a gcc builtin provided the kernel is not compiled with

Renamed the private copies of strlen and strcpy to gdb_strlen and
gdb_strcpy, respectively. This saves fixing the wrong return type
of the private strlen and makes the addresses of strlen and strcpy
unambiguous.

Backed out the previous commit, except for the parts that reduced
the magicness of 200. Cleaned up the remaining parts. Circularisation
of the list of malloc types was a kernel bug (now fixed). Interfering
with applications' definitions of pgtok is a system header bug (not
fixed).

Fixed corruption of the kmemstatistcs list. The first malloc()
with malloc type at the tail of the list changed the list from
linear to circular. This seemed to cause surprisingly few problems,
but it now causes weird output from `vmstat -m', probably because
a more important malloc type is now at the tail of the list.
Fix it by abusing ks_limit instead of ks_next as a flag for being
on the list. Don't forget to clear the flag when a malloc type is
uninit'ed. Uninit'ing is still fundamentally broken -- it loses
history.

Allow ``host:port/udp'' devices and support ``host:port/tcp'' as
being the same as the previous (still supported) ``host:port''
syntax for tcp socket devices.
A udp device uses synchronous ppp rather than async, and avoids
the double-retransmit overhead that comes with ppp over tcp (it's
usually a bad idea to transport IP over a reliable transport that
itself is using an unreliable transport). PPP over UDP provides
througput of ** 1.5Mb per second ** with all compression disabled,
maxing out a PPro/200 when running ppp twice, back-to-back.
This proves that PPPoE is plausable in userland....
This change adds a few more handler functions to struct device and
allows derivations of struct device (which may contain their own
data etc) to pass themselves through the unix domain socket for MP.
** At last **, struct physical has lost all the tty crud !
iov2physical() is now smart enough to restore the correct stack of
layers so that MP servers will work again.
The version number has bumped as our MP link transfer contents have
changed (they now may contain a `struct device').
Don't extract the protocol twice in MP mode (resulting in protocol
rejects for every MP packet). This was broken with my original
layering changes.
Add ``Physical'' and ``Sync'' log levels for logging the relevent
raw packets and add protocol-tracking LogDEBUG stuff in various
LayerPush & LayerPull functions.
Assign our physical device name for incoming tcp connections by
calling getpeername().
Assign our physical device name for incoming udp connections from
the address retrieved by the first recvfrom().
Completely change the way package_add() does its work. Now we
handle dependencies at a lower level and use package add for this.
Also made index searches stricter.
Erm, delete the package base hint again. Gotta lay off the crack!
I simply forgot that I'd already proven this to be a "really good idea that
unfortunately didn't work at all" the *last* time I tried it. Now
I remember. Hmmm. I WILL defeat this evil problem.

Removed global variable `Crtat'. This was once (bogusly) shared with
pcvt, but it had rotted into unuse here, and of course its type had
become inconsisent with its type in pcvt.
Divorce "dev_t" from the "major|minor" bitmap, which is now called
udev_t in the kernel but still called dev_t in userland.
Provide functions to manipulate both types:
major() umajor()
minor() uminor()
makedev() umakedev()
dev2udev() udev2dev()
For now they're functions, they will become in-line functions
after one of the next two steps in this process.
Return major/minor/makedev to macro-hood for userland.
Register a name in cdevsw[] for the "filedescriptor" driver.
In the kernel the udev_t appears in places where we have the
major/minor number combination, (ie: a potential device: we
may not have the driver nor the device), like in inodes, vattr,
cdevsw registration and so on, whereas the dev_t appears where
we carry around a reference to a actual device.
In the future the cdevsw and the aliased-from vnode will be hung
directly from the dev_t, along with up to two softc pointers for
the device driver and a few houskeeping bits. This will essentially
replace the current "alias" check code (same buck, bigger bang).
A little stunt has been provided to try to catch places where the
wrong type is being used (dev_t vs udev_t), if you see something
not working, #undef DEVT_FASCIST in kern/kern_conf.c and see if
it makes a difference. If it does, please try to track it down
(many hands make light work) or at least try to reproduce it
as simply as possible, and describe how to do that.
Without DEVT_FASCIST I belive this patch is a no-op.
Stylistic/posixoid comments about the userland view of the <sys/*.h>
files welcome now, from userland they now contain the end result.
Next planned step: make all dev_t's refer to the same devsw[] which
means convert BLK's to CHR's at the perimeter of the vnodes and
other places where they enter the game (bootdev, mknod, sysctl).
