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.
|

|
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.
