77GCC 4.7
78-------
79
80DragonFly has switched base compilers. GCC 4.7 is now the default
81compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make
82variable ceases to work now.
83
84Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
85/etc/make.conf to prohibit GCC 4.4 from building. However, using it is
86highly discouraged. There are a few packages in pkgsrc that do not build
87with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At
88this time, it is recommended to keep both compilers on the base system.

90SMP OPTION REMOVED
91------------------
92
93The SMP kernel option has been made a no-op. All kernels now feature SMP
94support. If you have 'options SMP' in your kernel config, you can as well
95remove it.

97DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED
98---------------------------------------------------------------------------
640dc18f
SZ
99
100The DEVICE_POLLING kernel option has been made a no-op and it has been
101replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your
102kernel config, you need to change it to IFPOLL_ENABLE.
103
1c297ed0
SW
104Also, the KTR_POLLING kernel option has been removed, so it must be
105removed from kernel configs that have it.

107BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED
108---------------------------------------------------

110The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA
111cards will no longer be detected.
112
e6f626a1
SW
113The same has been done for Stallion multiport serial controllers. stli(4)
114has been completely removed (along with the stlload(8) and stlstty(8)
558b0a0b
SW
115utilities) and stl(4) was changed to support only PCI cards. Similarly,
116ISA support was removed from cy(4) too. All these drivers are i386 only.

130
131The APIC_IO kernel option is no longer accepted after having been without
132effect for a while. The hw.ioapic_enable tunable now serves its purpose.
133If you have 'options APIC_IO' in your kernel config, you'll have to
134remove it.

148GCC 4.7
149-------
150
151GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non-
152default compiler in base (default is still GCC 4.4).
153
154Users who wish to build only GCC 4.4 have to replace NO_GCC41 with
155NO_GCC47 in /etc/make.conf.

157USB4BSD
158-------
159
160A new USB stack (from FreeBSD) has been brought in. The following
161modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass,
162usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk,
163and uaudio.
164
165It is not yet the default. To activate it, WANT_USB4BSD=yes has to
c7200221
SW
166be put in make.conf and device "usb4bsd" (quotes needed) has to
167replace device usb in the kernel config. After that, a full
168build/install/upgrade cycle is needed.
2508820f

169
170Note that this is experimental and incomplete, but we are interested
171in hearing about issues with it, of course.

184
185The following ISA only drivers have been removed along with a couple of
186associated userland tools:
187
188aha(4)
189asc(4) & sasc(1)
190ctx
191dgb(4)

204wt(4)
205
206Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC
207config and one (aha(4)) is in our X86_64_GENERIC kernel configuration
208file.
209
210If buildkernel complains about any of these drivers, just remove them
211from your kernel configuration.

219---------------------------------------
220Due to changes in the way we build with more than one make job, you
221will have to update install(1) and mkdir(1) prior to buildworld if you
222want to build with 'make -j':
223
224cd /usr/src/usr.bin/xinstall; make; make install; make clean

b1242318
SW
241GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has
242been made DragonFly's default Binutils.
30c91f0c
SW
243
244That means that any settings that set CCVER to 'gcc44' are not needed
245anymore. Instead, CCVER can be set to 'gcc41' to go back to using
246GCC 4.1.
247
b1242318
SW
248It also means that 'binutils221' as a value for BINUTILSVER has no
249effect anymore. 2.17 has been removed and 'binutils220' is available
250as an option.
251
5738210d 252The NO_GCC44 option has been removed and will not affect the build
30c91f0c
SW
253anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from
254building in a similar fashion.
255

273
274OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto.

JT
281A new loader (dloader) has been added which better handles booting from
282multiple kernel/module versions.
283
284To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below)
285
286 cd /usr/src
287 make buildworld
288 make installworld
289 make upgrade
290 make buildkernel KERNCONF=<KERNELNAME>
291 make installkernel KERNCONF=<KERNELNAME>

293Note that you must installworld and run the 'upgrade' target before
294installing the new kernel.

c983d16e 297-----
8eb0b612
JS
298
299BIND has been removed from the base system. The ldns and drill tools have
300been added for basic functionality. Use 'drill' where you would normally
301use nslookup or dig, or install BIND from pkgsrc. It's available as
302net/bind95, net/bind96, or net/bind97 as of this writing.
303
304This only affects older systems upgrading to 2.8. New 2.8+ installs
305include BIND as a pkgsrc package.

312Instructions on how to obtain and maintain DragonFly source code using git
313are in the development(7) manual page.
d2a0decc
MD
314
315To upgrade a DragonFly system from sources you run the following sequence:
316
317 cd /usr/src
318 make buildworld
319 make buildkernel KERNCONF=<KERNELNAME>
320 make installkernel KERNCONF=<KERNELNAME>
321 make installworld
322
323You will also want to run the 'upgrade' target to upgrade your /etc and the
324rest of your system. The upgrade target is aware of stale files created by
325older DragonFly installations and should delete them automatically.
326
327 make upgrade
328
a700883c
SW
329See the build(7) manual page for further information.
330
d2a0decc
MD
331Once you've done a full build of the world and kernel you can do incremental
332upgrades of either by using the 'quickworld' and 'quickkernel' targets
333instead of 'buildworld' and 'buildkernel'. If you have any problems with
a700883c 334the quick targets, try updating your repo first, and then a full buildworld
d2a0decc 335and buildkernel as shown above, before asking for help.

338+ UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 +
339+-----------------------------------------------------------------------+
340
341In 2.1 kernel and modules has moved to boot directory. For most cases
342this is handled automatically by 'make upgrade'. A few cases needs manual
343intervention:
344
345 * When installing a kernel without first doing a make buildworld,
346 installworld and upgrade to the same DESTDIR as kernel:
347 make DESTDIR/boot directory and move kernel and modules into this boot
348 directory; also move kernel.old and modules.old.
349 Typical example is vkernel(7), use (no modules used):
350
351 cd /var/vkernel
352 mkdir boot
353 chflags noschg kernel
354 mv kernel kernel.old boot
355 chflags schg boot/kernel
356
357 * When using a boot-only partition, /boot/loader.rc needs to be edited:
358 delete occurrences of '/boot/'.
359 These occurences can normally be deleted in any case, see loader(8).

362+ UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 +
363+-----------------------------------------------------------------------+
364
365In 1.9 major changes to the disk management infrastructure have taken
366place. make upgrade may not catch all of your disk devices in /dev,
367so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
45e80934
MD
368are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
369and MAKEDEV no longer exists.
d2a0decc
MD
370
371The biggest changes in 1.9 are:
372
373(1) That whole-slice devices such as da0s1 no longer share the same device
374 id as partition c devices such as da0s1c.
375
376(2) The whole-disk device (e.g. da0) is full raw access to the disk,
377 with no snooping or reserved sectors. Consequently you cannot run
378 disklabel on this device. Instead you must run disklabel on a
379 whole-slice device.
380
381(3) The 'compatibility' partitions now use slice 0 in the device name,
382 so instead of da0a you must specify da0s0a. Also, as per (1) above,
383 accessing the disklabel for the compatibility partitions must be
384 done via slice 0 (da0s0).
385
386(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
387 and CCD now run through the disk management layer and are assigned
388 real disk management devices. VN and CCD in particular do not usually
389 use a MBR and disklabels must be accessed through the compatibility
390 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
391 don't name it 'ccd0s0' in the config file.
392
393Generally speaking, you have to get used to running fdisk and disklabel on
394the correctly specified device names. A lot of the wiggle, such as running
395disklabel on a partition, has been removed.

404Kerberos IV (eBones) was removed from the tree, please consider moving to
405Kerberos 5 (Heimdal).
406
407> Package Management System
408---------------------------
409
410Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
411management system. The necessary tools to build and maintain packages
412are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
413directories are in your PATH variable.
414
415In order to obtain a reasonably current snapshot of the pkgsrc tree, use
416the tarball from NetBSD:
417
418 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
419 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
420
421This tree can then be kept up to date with cvs update:
422
423 cd /usr/pkgsrc; cvs up
424
425NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
426build and install the pkgsrc bootstrap manually:
427
428 cd /usr/pkgsrc/bootstrap

489Once you have built DragonFly you have to install it over FreeBSD. Since
490DragonFly does not track changes made by FreeBSD to its include file
491hierarchy and include file pollution can cause all sorts of unexpected
492compilation issues to come up, it is best to wipe your include hierarchy
493prior to installing DragonFly. Note that you should not wipe any installed
494FreeBSD header files or binaries until after you have successfully completed
495the build steps above.

f419daca 503will unconditionally upgrade the /etc files that sysops do not usually

SW
504mess around with, such as the files in /etc/rc.d. It will also remove any
505obsolete files such as utilities and manpages that have been removed from
506the system since the version you're coming from. If you are unsure we
507recommend that you make a backup of at least your /etc before applying
508this step. Note that DragonFly's RC system is basically RCNG from
509FreeBSD-5, but there are some differences in the contents of the RC files.

513NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
514Doing so might leave your system in an unusable state.

f419daca 516Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
b8cbf045
SW
517/usr/bin, and /usr/lib, and remove any stale files that you find. Please
518report these files to the DragonFly developers so that they can be added to
519the 'upgrade' target.
