Would you please commit this two-line patch to /sys/i386/isa/b004.c
(the Transputer driver) so that it at least compiles under 2.x
Haven't tried if the driver is working properly, but a kernel with
compiled-in driver has been running for two days now with no apparent
problems.

This is new version of Seagate ST01/02, Future Domain TMC-885, TMC-950
SCSI driver for FreeBSD. I started from the 2.0R version and mostly
rewrote it. New features are:
1) New probe algorithm. Old driver read the BIOS region of the adapter
memory and find the copyright string. The problem was in the BIOS itself:
it conflicted with IDE disks. The solution was to unplug it and
make the probe algorithm to work without it.
2) Proper timeout handling in numerous places where the driver
polls waiting for some event.
3) Assembler flagments added in critical places, mostly for data transfer
to of from the target. It was possible to make it faster,
but at the price of decreasing reliability.
4) Target-dependent delays when waiting for REQ deassert event.
Some devices seem to be slower (CD-ROMS, some tape drives),
and some seem to be too fast (disks). The driver tests the REQ
deassert timeout for each target and then uses it for polling.
5) Device flags added for SCSI parity control and sense request
priority control.
6) Generic cleanup, after which the driver became much more readable
(at least by me:).
7) Target data parity error logging is limited to avoid log file overflow.
8) Manual page added.

the wild, slippery orgy commence!
Gary Jennejohn, too studly for his own good, has finally come through with
the new, improved gdb 4.13. This gdb features:
o kgdb support - if this works (and I urge folks to test it), we can
finally purge the old and hateful version of kgdb from our source
tree.
o attach/detach support. See comments in README.FreeBSD for more
details.
o Well, it's newer. Our previous version was 4.11.
Comments and flames to gj, of course! :-)
Thanks, Gary. Much appreciated. The previous state of gdb/kgdb has been a
thorn in all of our sides for some time..

- The -a flag now works just as it does in SunOS: '-a' is actually
handled like a wildcard for all interfaces. 'ifconfig -a' displays
the status of all interfaces, 'ifconfig -a netmask 0xffffff00' sets
the netmask of all interfaces, and so forth. I don't know if many
people really need to be able to set the netmasks of all interfaces
at once, but the SunOS ifconfig seems to allow this, so there you
have it.
- An 'ether_status' function has been added to display the ethernet
address of all ethernet interfaces. Again, as in SunOS, you must
be root in order for this to work. The ethernet address is read
from /dev/kmem using kvm_open() and kvm_read(), much in the same
was as it's done with netstat. If you choose to install ifconfig
set-gid kmem then normal users will be able to see the ethernet
address as well, though this may not be desireable. This feature
requires a small change to the ifconfig Makefile: you need to link
with -lkvm in order to use the kvm_*() functions.

stat the pathname "" in order to decide that the pathname "/" is
a directory. This caused `cp kernel /' to fail if the kernel has
the POSIX behaviour of not allowing the pathname "" to be an alias
for ".". It presumably also caused `cp /etc/motd /' to fail in
the unlikely event that "." is not stat'able.
Be more careful about concatenating pathnames: don't check that
the pathname fits until prefixes have been discarded (the check
was too strict). Print the final pathname in error messages.
Terminate the target directory name properly for error messages.
Don't add a slash between components if there is already a slash.
Move definition of `stat_imask' to clock.c.
clock.c:
Rename `rtcmask' to `stat_imask' and export it. Rename `clkmask' to
`clk_imask' for consistency.
Only calculate TIMER_DIV(hz) once.
Merge debugging and "garbage" code to produce debugging code and format the
output better.
Make writertc() static inline and use it everywhere. Now all accesses to
the clock registers go through rtcin() and writertc().
Move rtc initialization to cpu_initclocks().
Merge enablertclock() with cpu_initclocks() and remove enablertclock().
The extra entry point was just a leftover from 1.1.5.
