- Make a number of filesystems work again when they are statically compiled
(blush)
- FIFOs are no longer optional; ``options FIFO'' removed from distributed
config files.
has no effect now, and MROUTING should never be defined by default.
(Eventually the code should be dynamically loadable.)
Also, allow for Pentium CPUs in GENERICBT kernels.
Add an `install' rule to Makefile.i386, which looks like this:
mv /kernel /kernel.old
install -c -m 555 -o root -g root -fschg kernel /
I'd like comments on whether or not you think it's a good idea to have
the kernel be immutable by default; I'm happy either way.
CVS:
Added "device pci" and "device ncr" lines for a generic kernel with
support for the NCR 53c810 PCI SCSI host adapter (with no interrupts
configured, ie. working with 100Hz timer interrupts only).
with BOUNCE_BUFFERS. This is more intuitive, and is better for future
multiplatform support. Added BOUNCE_BUFFERS option to the GENERIC and
LINT kernel config files.
This is the slowest and most stupid of our SCSI-drivers, but it is there
and it works. It has been tested with CD-ROM and disk.
It uses no interrupts, no DMA, just polled I/0.
Transfer-rate is <= 100Kbyte/sec.
If you set the jumpers on the board, you can change the unit-number and
you will be able to have four of these co-exist in one computer, why one
would do that is somewhat unclear though.
If I ever get my hand on the docs for this, I will improve it of course,
but for now we can install and access those CD-ROMs.
This inetrface should be used from now on.
pseudo device pty xx still keeps its meaning: a maximum of
xx ptys is allowed.
A ringbuffer is now 2040 bytes long, per Garrett Wollman's request.
The changes are inspired by the way NetBSD did it (thanks for that!),
though I made it slihghtly different, including the interface so
at least 75% of the allocated space is deallocated when the tty is
closed.
Note further that it is easy to modify the ringbuffer length runtime.
This will have to wait untill some later date...

Removed com port comments, since we are about to depricate the driver.
Fix several plaes in LINT where people have been cutting and pasting using
xterms :-(
a binary link-kit. Make all non-optional options (pagers, procfs) standard,
and update LINT to reflect new symtab requirements.
NB: -Wtraditional will henceforth be forgotten. This editing pass was
primarily intended to detect any constructions where the old code might
have been relying on traditional C semantics or syntax. These were all
fixed, and the result of fixing some of them means that -Wall is now a
realistic possibility within a few weeks.
John Dyson to make it reliably work under FreeBSD.
2) Added and enabled PROCFS in the GENERICxx and LINT kernels.
3) New execve() from me. Still work to be done here, but this version
works well and is needed before other changes can be made. For
a description of the design behind this, see freebsd-arch or
ask me.
4) Rewrote stack fault code; made user stack VM grow as needed rather
than all up front; improves performance a little and reduces
process memory requirements.
5) Incorporated fix from Gene Stark to fault/wire a user page table
page to fix a problem in copyout. This is a temporary fix and
is not appropriate for pageable page tables. For a description
of the problem, see Gene's post to the freebsd-hackers mailing
list.
6) Tighten up vm_page struct to reduce memory requirements for it. ifdef
pager page lock code as it's not being used currently.
7) Introduced new element to vmspace struct - vm_minsaddr; initial
(minimum) stack address. Compliment to vm_maxsaddr.
8) Added a panic if the allocation for process u-pages fails.
9) Improve performance and accuracy of kernel profiling by putting in
a little inline assembly instead of spl().
10) Made serial console with sio driver work. Still has problems with
serial input, but is almost useable.
11) Added -Bstatic to SYSTEM_LD in Makefile.i386 so that kernels will
build properly with the new ld.
pccons or syscons usage. Modified comment in LINT for FAT_CURSOR.
Now the FAT_CURSOR can be controlled over the option, instead of hacking
syscons.c and pccons.c.
other bio type devices.
Add mcd0 (mitsumi cd rom driver), to bad that GENERICBT is to large,
otherwise I could add this driver to it too.

Change the cpu "i386" line to 2 lines:
cpu "I386_CPU"
cpu "I486_CPU"
This is so we can do real CPU classification of code.
Fix missing depend for assym.s which does depend on genassym.c
wd80x3 class boards can be configured to the GENERIC kernels.
