15SMP OPTION REMOVED
16------------------

18The SMP kernel option has been made a no-op. All kernels now feature SMP
19support. If you have 'options SMP' in your kernel config, you can as well
20remove it.

24
25The DEVICE_POLLING kernel option has been made a no-op and it has been
26replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your
27kernel config, you need to change it to IFPOLL_ENABLE.
28

29Also, the KTR_POLLING kernel option has been removed, so it must be
30removed from kernel configs that have it.

38The same has been done for Stallion multiport serial controllers. stli(4)
39has been completely removed (along with the stlload(8) and stlstty(8)
558b0a0b

56The APIC_IO kernel option is no longer accepted after having been without

74-------
75
76GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non-
77default compiler in base (default is still GCC 4.4).
78
79Users who wish to build only GCC 4.4 have to replace NO_GCC41 with
80NO_GCC47 in /etc/make.conf.

82USB4BSD
83-------
84
85A new USB stack (from FreeBSD) has been brought in. The following
86modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass,
87usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk,
88and uaudio.
89
90It is not yet the default. To activate it, WANT_USB4BSD=yes has to
c7200221
SW
91be put in make.conf and device "usb4bsd" (quotes needed) has to
92replace device usb in the kernel config. After that, a full
93build/install/upgrade cycle is needed.

145Due to changes in the way we build with more than one make job, you
146will have to update install(1) and mkdir(1) prior to buildworld if you
147want to build with 'make -j':

166GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has
167been made DragonFly's default Binutils.
30c91f0c
SW
168
169That means that any settings that set CCVER to 'gcc44' are not needed
170anymore. Instead, CCVER can be set to 'gcc41' to go back to using
171GCC 4.1.
172
b1242318
SW
173It also means that 'binutils221' as a value for BINUTILSVER has no
174effect anymore. 2.17 has been removed and 'binutils220' is available
175as an option.
176
5738210d 177The NO_GCC44 option has been removed and will not affect the build
30c91f0c
SW
178anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from
179building in a similar fashion.
180

199OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto.

JT
206A new loader (dloader) has been added which better handles booting from
207multiple kernel/module versions.
208
209To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below)
210
211 cd /usr/src
212 make buildworld
213 make installworld
214 make upgrade
215 make buildkernel KERNCONF=<KERNELNAME>
216 make installkernel KERNCONF=<KERNELNAME>
217
218Note that you must installworld and run the 'upgrade' target before
219installing the new kernel.

223
224BIND has been removed from the base system. The ldns and drill tools have
225been added for basic functionality. Use 'drill' where you would normally
226use nslookup or dig, or install BIND from pkgsrc. It's available as
227net/bind95, net/bind96, or net/bind97 as of this writing.
228
229This only affects older systems upgrading to 2.8. New 2.8+ installs
230include BIND as a pkgsrc package.

238are in the development(7) manual page.
d2a0decc

239
240To upgrade a DragonFly system from sources you run the following sequence:
241
242 cd /usr/src
243 make buildworld
244 make buildkernel KERNCONF=<KERNELNAME>
245 make installkernel KERNCONF=<KERNELNAME>
246 make installworld
247
248You will also want to run the 'upgrade' target to upgrade your /etc and the
249rest of your system. The upgrade target is aware of stale files created by
250older DragonFly installations and should delete them automatically.
251
252 make upgrade
253

254See the build(7) manual page for further information.
255
d2a0decc
MD
256Once you've done a full build of the world and kernel you can do incremental
257upgrades of either by using the 'quickworld' and 'quickkernel' targets
258instead of 'buildworld' and 'buildkernel'. If you have any problems with
a700883c 259the quick targets, try updating your repo first, and then a full buildworld
d2a0decc 260and buildkernel as shown above, before asking for help.

263+ UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 +
264+-----------------------------------------------------------------------+
265
266In 2.1 kernel and modules has moved to boot directory. For most cases
267this is handled automatically by 'make upgrade'. A few cases needs manual
268intervention:
269
270 * When installing a kernel without first doing a make buildworld,
271 installworld and upgrade to the same DESTDIR as kernel:
272 make DESTDIR/boot directory and move kernel and modules into this boot
273 directory; also move kernel.old and modules.old.
274 Typical example is vkernel(7), use (no modules used):
275
276 cd /var/vkernel
277 mkdir boot
278 chflags noschg kernel
279 mv kernel kernel.old boot
280 chflags schg boot/kernel
281
282 * When using a boot-only partition, /boot/loader.rc needs to be edited:
283 delete occurrences of '/boot/'.
284 These occurences can normally be deleted in any case, see loader(8).

288+-----------------------------------------------------------------------+
289
290In 1.9 major changes to the disk management infrastructure have taken
291place. make upgrade may not catch all of your disk devices in /dev,
292so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
45e80934
MD
293are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
294and MAKEDEV no longer exists.
d2a0decc
MD
295
296The biggest changes in 1.9 are:
297
298(1) That whole-slice devices such as da0s1 no longer share the same device
299 id as partition c devices such as da0s1c.
300
301(2) The whole-disk device (e.g. da0) is full raw access to the disk,
302 with no snooping or reserved sectors. Consequently you cannot run
303 disklabel on this device. Instead you must run disklabel on a
304 whole-slice device.
305
306(3) The 'compatibility' partitions now use slice 0 in the device name,
307 so instead of da0a you must specify da0s0a. Also, as per (1) above,
308 accessing the disklabel for the compatibility partitions must be
309 done via slice 0 (da0s0).
310
311(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
312 and CCD now run through the disk management layer and are assigned
313 real disk management devices. VN and CCD in particular do not usually
314 use a MBR and disklabels must be accessed through the compatibility
315 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
316 don't name it 'ccd0s0' in the config file.
317
318Generally speaking, you have to get used to running fdisk and disklabel on
319the correctly specified device names. A lot of the wiggle, such as running
320disklabel on a partition, has been removed.

329Kerberos IV (eBones) was removed from the tree, please consider moving to
330Kerberos 5 (Heimdal).
331
332> Package Management System
333---------------------------
334
335Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
336management system. The necessary tools to build and maintain packages
337are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
338directories are in your PATH variable.
339
340In order to obtain a reasonably current snapshot of the pkgsrc tree, use
341the tarball from NetBSD:
342
343 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
344 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
345
346This tree can then be kept up to date with cvs update:
347
348 cd /usr/pkgsrc; cvs up
349
350NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
351build and install the pkgsrc bootstrap manually:
352
353 cd /usr/pkgsrc/bootstrap

391You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
392FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
393FreeBSD. Note that the DragonFly buildworld target does not try to reuse
394make depend information, it starts from scratch, so no pre-cleaning of the
395object hierarchy is necessary.

414Once you have built DragonFly you have to install it over FreeBSD. Since
415DragonFly does not track changes made by FreeBSD to its include file
416hierarchy and include file pollution can cause all sorts of unexpected
417compilation issues to come up, it is best to wipe your include hierarchy
418prior to installing DragonFly. Note that you should not wipe any installed
419FreeBSD header files or binaries until after you have successfully completed
420the build steps above.

424 make installkernel KERNCONF=<KERNELNAME>
425 make installworld
fb12f484 426
b8cbf045 427Then you need to upgrade your system. DragonFly's 'make upgrade' target
f419daca 428will unconditionally upgrade the /etc files that sysops do not usually
b8cbf045
SW
429mess around with, such as the files in /etc/rc.d. It will also remove any
430obsolete files such as utilities and manpages that have been removed from
431the system since the version you're coming from. If you are unsure we
432recommend that you make a backup of at least your /etc before applying
433this step. Note that DragonFly's RC system is basically RCNG from
434FreeBSD-5, but there are some differences in the contents of the RC files.

435
436 make upgrade
437
b8cbf045
SW
438NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
439Doing so might leave your system in an unusable state.
440
f419daca 441Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
b8cbf045
SW
442/usr/bin, and /usr/lib, and remove any stale files that you find. Please
443report these files to the DragonFly developers so that they can be added to
444the 'upgrade' target.
