Updating Information for FreeBSD current users
This file is maintained by imp@village.org. Please send new entries
directly to him. See end of file for further details.
19990509:
Most of the problems with newbus have been corrected, but
it is still current and evolving.
libcam's ABI has changed. You must recompile the world and
any ports that use it.
19990427:
Massive changes to SMP went into the tree that should speed
things up. However, if you experience problems with SMP
machines, you can back off to the PRE_SMP_VMSHARE tag in the
CVS repository (or run an MP kernel).
19990420:
Pccardd and the pccard bus in general seem to be broken or
most people. Soren has patches to make it better for some,
but not all people. Work is underway to make it better for
all people.
19990416:
new bus changes integrated into -current. Many problems were
initially reported, but most have been fixed. You'll need a
new config and to tweak your kernel config file the way that
GENERIC was tweaked. Keep a copy of your old kernel when
upgrading in case your new kernel doesn't work (and report the
breakage to current@freebsd.org).
As of 19990421 the remaining problems/quirks are
o sio no longer supports pnp nor pccard. This will be corrected,
but the new pccard code needs to be completed.
o Some of the sound drivers broke for some people. It seems
inconsistant as to who/what/when/where things broke.
o Duplicate device entries in your config do not work. Previously
they were silently ignored. psm0 seems to be the most common
duplicate choice, although some reports have come in from people
that wired their scsi disk entries.
o You must move the keyboard and mouse attachments from the
isa bus to the atkbdc bus. See GENERIC for details.
o Machines with multiple host-pci bridges (Intel 450NX) will not
probe the second pci bus.
o Some probe ordering may have changed, so device naming may change
with the new kernel. If you have multiple devices, please double
check to make sure they didn't move. This is especially true
for cards on different buses.
o The bus attachment for vga0 is always isa0 and never pci0 when
it is in fact a pci card. It is safe to ignore this.
o The format of the boot messages has changed (and is not
guaranteed to be constant for a while) so you may see this
in some shell scripts that diff dmesg from day to day as well
as scripts that parse dmesg output.
19990414:
cc -aout sometimes has problems compiling with -g, remove -g
from those compilation units affected until this is corrected.
cc -aout has problems with producing some threaded libraries,
so make world -DWANT_AOUT is not functional at this time.
Since make world for a.out isn't functional, you cannot do
make aout-to-elf from a pre-egcs a.out system. To work around
this problem, make aout-to-elf using 3.1-stable first (or a
pre egcs -current) and then a simple make world will take you
the rest of the way with a -current source base.
19990413:
Make -j works again for make world. As always, use it with
care, and be sure to try a make world w/o -j before reporting
problems (that is, know if the problem exists w/o -j before
reporting the problem with -j).
19990413:
Note cc -aout, which had been broken since the conversion to
egcs, now supposedly works. If you have rebuilt things like
XFree86 a.out libraries, you should rebuild them again or
progams that use them, including netscape, will fail to work.
19990409:
NOTE: New c++ compiler cannot be used with c++ binaries from
the old compiler and vice versa.
19990408:
In recent days egcs has been imported into the tree. A number
of problems have been discussed in -current. Here is a highlight
of a few of the more common ones. With the exception of make
-j n, they have been claimed to have been fixed.
c++ is broken after make world: This is correct. Because we
changed compilers two make worlds are necessary to get C++
working again. The code generated by the old compiler and new
compiler are not compatible, so things wind up being
undefined.
cpp is broken in make world: There was a window where cpp
would be built incorrectly. The fix for this is
cd src/gnu/usr.bin/cc
make clean
make all
make install
and this should correct your problems. See the -current
archives for a version of this that does moer cleaning.
Make -j n doesn't work. Work contiunes to make this work,
I've seen no reports of success as of April 7th.
19990329:
Previously, one would define "NOAOUT" to keep from building
the legacy a.out bits. Now one would define "WANT_AOUT" to
build them.
19990316:
The name of the old wd.c and atapi.c based CDROM driver has
been changed back to wcd. So update your config file to use
"device wcd" instead of "device acd".
19990314:
For those of you using the VN device as a loadable module,
please be aware that the new VN device has been committed to
-4.x and cannot yet be used as a loadable module. This will
be fixed in the future.
19990309:
New loader.rc mechanism. Please see src/sys/boot/README for
details.
19990225:
struct proc size changed. Recompile kernel and the
usual suspects. Make world if in doubt.
19990214:
The nlpt driver has changed names back to be the lpt driver.
See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html
for proper configuration details.
19990210:
The 'lpt' driver is now obsolete. Replace it with the 'nlpt'
driver and 'ppbus' controller combination.
19990209:
New devstat API requires recompilation of libdevstat, systat,
iostat, vmstat and rpc.rstatd. A new kernel is also required.
make world + building a kernel should do all of this. Any
ports that use devstat need to be recompiled as well.
19990125:
Linux threads options has gone away (they are now standard in
the FreeBSD kernel). A recompile of all libkvm using programs
is in order (or better yet a make world).
19990122:
On or about this date there was a small window when the boot
blocks had some minor problems which seemed to force one to
edit /etc/fstab. This has been corrected, if you are seeing this
problem, please rebuild and reinstall your boot blocks.
19990121:
Vinum has changed. The "vinum read" command has changed. For
updates, please see
http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current
for details.
Matt Dillon committed a boatload of VM changes, for
information please see
http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current
or
http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current
for details. These changes will likely not impact anybody,
but large chagnes to the VM need at least a heads up.
19990120:
Stable branch created. You might want to consider using this
branch. It is tagged with RELENG_3.
19990119:
More work on the syscons driver has been committed. Since
files moved around, you will need to reconfigure your kernel,
and make clean; make depend before rebuilding the kernel. No
config file changes are needed.
19990111:
New keyboard and video card drivers are introduced as the first
stage of console driver reorganization. You are required to
update the kernel configuration file and rebuild the kernel.
kbdcontrol, vidcontrol, and screen savers also need recompilation.
The instruction can be found in
http://www.freebsd.org/~yokota/sc_update.txt
It has notes on splash screen too.
19990106:
Robert Nordier was kind enough to make this page to enable people to
install the new bootblocks:
http://www.freebsd.org/~rnordier/boot.txt
When updating to ELF, make sure that you have updated your
/etc/rc files which have different ldconfig invocations for
elf and aout. Otherwise things like X will stop working with
messages about being unable to find library files. The
mergemaster utility in ports/sysutils/mergemaster helps to
keep critical files like this in sync, and its use is
recommended.
19990104:
Information about ELF day (see 19981230) can be found in
http://www.freebsd.org/~peter/elfday.html
about the upcoming change, its motivations and instructions
for doing the upgrade.
19981230:
You should install new bootblocks now. The ELF kernel will
become default soon. In addition, you'll need to upgrade
your userland programs to ELF before then as well. Use
make aout-to-elf to upgrade your userland programs (old
a.out programs in, for example, /usr/local/bin will
continue to work, even after the upgrade). See src/Makefile
for more details.
19981224:
The old wcd driver has been deleted from the kernel. The
driver that replaces it is named acd. You'll need to change
this in your configuration files.
Failure to do this will result in "ATAPI CD-ROMs not
configured" at boot time.
The floppy tape driver (ft) has been removed from the kernel,
with no replacement driver.
19981202:
New groups from 19981201 commented out of mtree, so they
aren't strictly needed, but still a good idea to have.
19981201:
New user/group added: bind. From src/etc/master.passwd and
src/etc/group:
% grep <newstuff> /usr/src/etc/group
bind:*:53:
% grep <newstuff> /usr/src/etc/master.passwd
tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin
kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin
bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin
19981118:
PAM integrated into the tree. Requires new /etc/pam.conf file
to silence warnings from authentication programs (login, etc).
See src/etc/pam.conf for a sample.
This file contains a list, in reverse chronologocal order, of major
breakages in tracking -current. Not all things will be listed here,
and it only starts on Novemeber 18, 1998. If you have an earlier
version of FreeBSD, you are on your own to get to November 18, 1998.
Please filter your entries through Warner (imp@village.org) so that
the style, formatting, etc of this file can be maintained.
