Kill duplicates for programs that have been in the boot crunched image
as well as on the fixit floppy (pwd, newfs, hostname, test). Our
space is really too valuable to have them around there twice. I doubt
pwd needs to be there at all since it's a builtin into sh(1) anyway
(oh, and the same applies to test(1) IIRC), but heck, leave them by
now.
Use the new `fixit' target in MAKEDEV to create the /dev nodes on
the floppy, instead of including the kitchensink...
Finally, tune the values used for creating the floppy. I currently
end up with
Filesystem 1K-blocks Used Avail Capacity iused ifree %iused
/dev/vnn0c 1363 1301 -47 104% 368 14 96%
...which is not quite ideal yet, but at least a working configuration
again.
longer really suitable as a default to create the various /dev nodes
to be contained on the fixit floppy, since all our proud new devide
nodes finally made the fixit floppy run over...
So instead create a new target titled `fixit' which creates just the
dev nodes for a single unit per each default driver; whoever needs
more of them is free to create whatever he needs, perhaps after
killing unused nodes before. There were more than 700 /dev nodes on
the floppy before that action, and it's still around 350 now. I doubt
all the various /dev/ugen* entries are really useful on such a tool,
so people, please check, and if you feel like more could be eliminated
from that floppy, kill'em.
While i was at it, removed traces of ft(8) that still survived even
though the driver has long since been dead.
That's step #1. #2 will follow...

History:
The bulk of this code was obtained from NetBSD approximately one year
ago (I have taken care to preserve the original NetBSD copyrights and
I thank the authors for their work.) At that time, the OSF/1 code was
what was left over from their initial bootstrapping off of OSF/1 and
did not provide support for executing shared binaries.
I have independently added support for shared libraries, and support
for some of the more obscure system calls. This code has been
available for testing and comment since January of 1999 and running on
production machines here at Duke since April.
Known working applications include:
- Netscape (all versions I've tried)
- Mathematica 3.0.2
- Splus 3.4
- ArcInfo 7.1
- Matlab (version unknown)
- SimOS
- Atom instrumented binaries (built on a real OSF/1 system)
Applications which are known not to work:
- All applications linking to libmach
- Adobe Acrobat (uses libmach)
This has been tested with applications running against shared
libraries from OSF/1 (aka Tru64) 4.0D and 4.0F.

occur due to np->n_size potentially changing if nfs_getcacheblk()
blocks in nfs_write().
Second, under -current we must supply the proper bufsize when obtaining
buffers that straddle the EOF, but due to the fact that np->n_size can
change out from under us it is possible that we may specify the wrong
buffer size and wind up truncating dirty data written by another
process.
Both problems are solved by implementing nfs_rslock(), which allows us
to lock around sensitive buffer cache operations such as those that
occur when appending to a file.
It is believed that this race is responsible for causing dirtyoff/dirtyend
and (in stable) validoff/validend to exceed the buffer size. Therefore
we have now added a warning printf for the dirtyoff/end case in current.
However, we have introduced a new problem which we need to fix at some
point, and that is that soft or intr NFS mounts may become
uninterruptable from the point of view of process A which is stuck waiting
on rslock while process B is stuck doing the rpc. To unstick process A,
process B would have to be interrupted first.

tsunami systems and the PCI bus-numbering system of FreeBSD. Eg, the former
allows for 2 PCI bus 2's (one each on hoses 0 and 1) while the latter
needs to give each PCI bus a unique monotonically increasing number.
It has been fairly well tested and correctly maps machines with a ppb on
hose 1 as well as machines with ppbs on both hoses.
DS10s remain untested, as I do not have a pci card with a ppb which will
pass POST in a tsunami.
This is a house of cards.
MAN8+= rstat_svc.8
The file it talks about doesn't exist on FreeBSD, so there's no point in
installing the manual page. There was already a comment to this effect in
this file, but the entry hadn't been commented out.
rstat.1 and rstat_svc.8 can probably actually be removed.

This requires my recent update to libdialog to work properly and will

The variables "m_mclalloc_wid" and "m_mballoc_wid" were not in the
proper place. They should have been in uipc_mbuf.c and have been global,
not in mbuf.h and local per each file that uses mbuf.h.
Sorta bug fix:
In mbuf.h, the definitions of various things for KERNEL and not
KERNEL cases were very screwy. This fixes all of that which I could
find.
- Add a flag DC_TX_INTR_ALWAYS which causes the transmit code to
request a TX done interrupt for every packet. The PNIC seems to need
this to insure that the sent TX buffers get reaped in a timely fashion.
- Try to unreset the SIA as soon as possible after resetting the whole
chip.
- Change dcphy to support either 10/100 or 10Mbps only NICs. The
built-in 21143 ethernet in Compaq Presario machines is 10Mbps only
and it doesn't work right if we try to advertise 100Mbps modes during
autoneg. When restricted to only 10mbps modes, it works fine.
Note that for now, I detect this condition by checking the PCI
subsystem ID on this NIC (which has a Compaq vendor/device ID).
Yes, I know that's what the SROM is supposed to be for. I'm deliberately
ignoring the SROM wherever possible. Sue me.
The latter two fixes allow if_dc to work correctly with the built-in
ethernet on certain Compaq Presario boxes. There are liable to be quite
a few people using these as their home systems who might want to try
FreeBSD; may as well be nice to them.
Now if anybody out there has an Alpha miata with 10Mbps ethernet and
can show me the output from pciconf -l on their system, I'd be grateful.

NFS read performance increases from 8.5 MBytes/sec to 10 MB/sec (maxed
