1 Updating Information for FreeBSD current users
3 This file is maintained by imp@village.org. Please send new entries
4 directly to him. See end of file for further details.
7 Most of the problems with newbus have been corrected, but
8 it is still current and evolving.
10 libcam's ABI has changed. You must recompile the world and
11 any ports that use it.
14 Massive changes to SMP went into the tree that should speed
15 things up. However, if you experience problems with SMP
16 machines, you can back off to the PRE_SMP_VMSHARE tag in the
17 CVS repository (or run an MP kernel).
20 Pccardd and the pccard bus in general seem to be broken or
21 most people. Soren has patches to make it better for some,
22 but not all people. Work is underway to make it better for
26 new bus changes integrated into -current. Many problems were
27 initially reported, but most have been fixed. You'll need a
28 new config and to tweak your kernel config file the way that
29 GENERIC was tweaked. Keep a copy of your old kernel when
30 upgrading in case your new kernel doesn't work (and report the
31 breakage to current@freebsd.org).
33 As of 19990421 the remaining problems/quirks are
35 o sio no longer supports pnp nor pccard. This will be corrected,
36 but the new pccard code needs to be completed.
37 o Some of the sound drivers broke for some people. It seems
38 inconsistant as to who/what/when/where things broke.
39 o Duplicate device entries in your config do not work. Previously
40 they were silently ignored. psm0 seems to be the most common
41 duplicate choice, although some reports have come in from people
42 that wired their scsi disk entries.
43 o You must move the keyboard and mouse attachments from the
44 isa bus to the atkbdc bus. See GENERIC for details.
45 o Machines with multiple host-pci bridges (Intel 450NX) will not
46 probe the second pci bus.
47 o Some probe ordering may have changed, so device naming may change
48 with the new kernel. If you have multiple devices, please double
49 check to make sure they didn't move. This is especially true
50 for cards on different buses.
51 o The bus attachment for vga0 is always isa0 and never pci0 when
52 it is in fact a pci card. It is safe to ignore this.
53 o The format of the boot messages has changed (and is not
54 guaranteed to be constant for a while) so you may see this
55 in some shell scripts that diff dmesg from day to day as well
56 as scripts that parse dmesg output.
59 cc -aout sometimes has problems compiling with -g, remove -g
60 from those compilation units affected until this is corrected.
62 cc -aout has problems with producing some threaded libraries,
63 so make world -DWANT_AOUT is not functional at this time.
65 Since make world for a.out isn't functional, you cannot do
66 make aout-to-elf from a pre-egcs a.out system. To work around
67 this problem, make aout-to-elf using 3.1-stable first (or a
68 pre egcs -current) and then a simple make world will take you
69 the rest of the way with a -current source base.
72 Make -j works again for make world. As always, use it with
73 care, and be sure to try a make world w/o -j before reporting
74 problems (that is, know if the problem exists w/o -j before
75 reporting the problem with -j).
78 Note cc -aout, which had been broken since the conversion to
79 egcs, now supposedly works. If you have rebuilt things like
80 XFree86 a.out libraries, you should rebuild them again or
81 progams that use them, including netscape, will fail to work.
84 NOTE: New c++ compiler cannot be used with c++ binaries from
85 the old compiler and vice versa.
88 In recent days egcs has been imported into the tree. A number
89 of problems have been discussed in -current. Here is a highlight
90 of a few of the more common ones. With the exception of make
91 -j n, they have been claimed to have been fixed.
93 c++ is broken after make world: This is correct. Because we
94 changed compilers two make worlds are necessary to get C++
95 working again. The code generated by the old compiler and new
96 compiler are not compatible, so things wind up being
99 cpp is broken in make world: There was a window where cpp
100 would be built incorrectly. The fix for this is
101 cd src/gnu/usr.bin/cc
105 and this should correct your problems. See the -current
106 archives for a version of this that does moer cleaning.
108 Make -j n doesn't work. Work contiunes to make this work,
109 I've seen no reports of success as of April 7th.
112 Previously, one would define "NOAOUT" to keep from building
113 the legacy a.out bits. Now one would define "WANT_AOUT" to
117 The name of the old wd.c and atapi.c based CDROM driver has
118 been changed back to wcd. So update your config file to use
119 "device wcd" instead of "device acd".
122 For those of you using the VN device as a loadable module,
123 please be aware that the new VN device has been committed to
124 -4.x and cannot yet be used as a loadable module. This will
125 be fixed in the future.
128 New loader.rc mechanism. Please see src/sys/boot/README for
132 struct proc size changed. Recompile kernel and the
133 usual suspects. Make world if in doubt.
136 The nlpt driver has changed names back to be the lpt driver.
137 See ppbus(4) or http://www.freebsd.org/~nsouch/ppbus.html
138 for proper configuration details.
141 The 'lpt' driver is now obsolete. Replace it with the 'nlpt'
142 driver and 'ppbus' controller combination.
145 New devstat API requires recompilation of libdevstat, systat,
146 iostat, vmstat and rpc.rstatd. A new kernel is also required.
147 make world + building a kernel should do all of this. Any
148 ports that use devstat need to be recompiled as well.
151 Linux threads options has gone away (they are now standard in
152 the FreeBSD kernel). A recompile of all libkvm using programs
153 is in order (or better yet a make world).
156 On or about this date there was a small window when the boot
157 blocks had some minor problems which seemed to force one to
158 edit /etc/fstab. This has been corrected, if you are seeing this
159 problem, please rebuild and reinstall your boot blocks.
162 Vinum has changed. The "vinum read" command has changed. For
165 http://www.freebsd.org/cgi/getmsg.cgi?fetch=800363+0+current/freebsd-current
169 Matt Dillon committed a boatload of VM changes, for
170 information please see
172 http://www.freebsd.org/cgi/getmsg.cgi?fetch=886676+0+current/freebsd-current
174 http://www.freebsd.org/cgi/getmsg.cgi?fetch=827400+0+current/freebsd-current
176 for details. These changes will likely not impact anybody,
177 but large chagnes to the VM need at least a heads up.
180 Stable branch created. You might want to consider using this
181 branch. It is tagged with RELENG_3.
184 More work on the syscons driver has been committed. Since
185 files moved around, you will need to reconfigure your kernel,
186 and make clean; make depend before rebuilding the kernel. No
187 config file changes are needed.
190 New keyboard and video card drivers are introduced as the first
191 stage of console driver reorganization. You are required to
192 update the kernel configuration file and rebuild the kernel.
193 kbdcontrol, vidcontrol, and screen savers also need recompilation.
194 The instruction can be found in
196 http://www.freebsd.org/~yokota/sc_update.txt
198 It has notes on splash screen too.
201 Robert Nordier was kind enough to make this page to enable people to
202 install the new bootblocks:
204 http://www.freebsd.org/~rnordier/boot.txt
206 When updating to ELF, make sure that you have updated your
207 /etc/rc files which have different ldconfig invocations for
208 elf and aout. Otherwise things like X will stop working with
209 messages about being unable to find library files. The
210 mergemaster utility in ports/sysutils/mergemaster helps to
211 keep critical files like this in sync, and its use is
215 Information about ELF day (see 19981230) can be found in
217 http://www.freebsd.org/~peter/elfday.html
219 about the upcoming change, its motivations and instructions
220 for doing the upgrade.
223 You should install new bootblocks now. The ELF kernel will
224 become default soon. In addition, you'll need to upgrade
225 your userland programs to ELF before then as well. Use
226 make aout-to-elf to upgrade your userland programs (old
227 a.out programs in, for example, /usr/local/bin will
228 continue to work, even after the upgrade). See src/Makefile
232 The old wcd driver has been deleted from the kernel. The
233 driver that replaces it is named acd. You'll need to change
234 this in your configuration files.
236 Failure to do this will result in "ATAPI CD-ROMs not
237 configured" at boot time.
239 The floppy tape driver (ft) has been removed from the kernel,
240 with no replacement driver.
243 New groups from 19981201 commented out of mtree, so they
244 aren't strictly needed, but still a good idea to have.
247 New user/group added: bind. From src/etc/master.passwd and
249 % grep <newstuff> /usr/src/etc/group
251 % grep <newstuff> /usr/src/etc/master.passwd
252 tty:*:4:65533::0:0:Tty Sandbox:/:/sbin/nologin
253 kmem:*:5:65533::0:0:KMem Sandbox:/:/sbin/nologin
254 bind:*:53:53::0:0:Bind Sandbox:/:/sbin/nologin
257 PAM integrated into the tree. Requires new /etc/pam.conf file
258 to silence warnings from authentication programs (login, etc).
259 See src/etc/pam.conf for a sample.
261 This file contains a list, in reverse chronologocal order, of major
262 breakages in tracking -current. Not all things will be listed here,
263 and it only starts on Novemeber 18, 1998. If you have an earlier
264 version of FreeBSD, you are on your own to get to November 18, 1998.
266 Please filter your entries through Warner (imp@village.org) so that
267 the style, formatting, etc of this file can be maintained.
