15OLDER NETWORK DRIVERS MOVED TO I386 ONLY
16----------------------------------------
17
18The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar
19and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be
20removed in kernel configs derived from X86_64_GENERIC.

108GCC 4.7
109-------
110
111DragonFly has switched base compilers. GCC 4.7 is now the default
112compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make
113variable ceases to work now.
114
115Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
116/etc/make.conf to prohibit GCC 4.4 from building. However, using it is
117highly discouraged. There are a few packages in pkgsrc that do not build
118with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At
119this time, it is recommended to keep both compilers on the base system.
120

121SMP OPTION REMOVED
122------------------
123
124The SMP kernel option has been made a no-op. All kernels now feature SMP
125support. If you have 'options SMP' in your kernel config, you can as well
126remove it.

640dc18f
SZ
130
131The DEVICE_POLLING kernel option has been made a no-op and it has been
132replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your
133kernel config, you need to change it to IFPOLL_ENABLE.
134
1c297ed0
SW
135Also, the KTR_POLLING kernel option has been removed, so it must be
136removed from kernel configs that have it.

141The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA
142cards will no longer be detected.
143
e6f626a1
SW
144The same has been done for Stallion multiport serial controllers. stli(4)
145has been completely removed (along with the stlload(8) and stlstty(8)
558b0a0b
SW
146utilities) and stl(4) was changed to support only PCI cards. Similarly,
147ISA support was removed from cy(4) too. All these drivers are i386 only.

161
162The APIC_IO kernel option is no longer accepted after having been without
163effect for a while. The hw.ioapic_enable tunable now serves its purpose.
164If you have 'options APIC_IO' in your kernel config, you'll have to
165remove it.

179GCC 4.7
180-------
181
182GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non-
183default compiler in base (default is still GCC 4.4).
184
185Users who wish to build only GCC 4.4 have to replace NO_GCC41 with
186NO_GCC47 in /etc/make.conf.

SW
188USB4BSD
189-------
190
191A new USB stack (from FreeBSD) has been brought in. The following
192modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass,
193usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk,
194and uaudio.
195
196It is not yet the default. To activate it, WANT_USB4BSD=yes has to
c7200221
SW
197be put in make.conf and device "usb4bsd" (quotes needed) has to
198replace device usb in the kernel config. After that, a full
199build/install/upgrade cycle is needed.

201Note that this is experimental and incomplete, but we are interested
202in hearing about issues with it, of course.

216The following ISA only drivers have been removed along with a couple of
217associated userland tools:
218
219aha(4)
220asc(4) & sasc(1)
221ctx
222dgb(4)

235wt(4)
236
237Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC
238config and one (aha(4)) is in our X86_64_GENERIC kernel configuration
239file.
240
241If buildkernel complains about any of these drivers, just remove them
242from your kernel configuration.

251Due to changes in the way we build with more than one make job, you
252will have to update install(1) and mkdir(1) prior to buildworld if you
253want to build with 'make -j':

272GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has
273been made DragonFly's default Binutils.
30c91f0c
SW
274
275That means that any settings that set CCVER to 'gcc44' are not needed
276anymore. Instead, CCVER can be set to 'gcc41' to go back to using
277GCC 4.1.
278
b1242318
SW
279It also means that 'binutils221' as a value for BINUTILSVER has no
280effect anymore. 2.17 has been removed and 'binutils220' is available
281as an option.
282
5738210d 283The NO_GCC44 option has been removed and will not affect the build
30c91f0c
SW
284anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from
285building in a similar fashion.

305OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto.

312A new loader (dloader) has been added which better handles booting from
313multiple kernel/module versions.
314
315To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below)
316
317 cd /usr/src
318 make buildworld
319 make installworld
320 make upgrade
321 make buildkernel KERNCONF=<KERNELNAME>
322 make installkernel KERNCONF=<KERNELNAME>

JS
329
330BIND has been removed from the base system. The ldns and drill tools have
331been added for basic functionality. Use 'drill' where you would normally
332use nslookup or dig, or install BIND from pkgsrc. It's available as
333net/bind95, net/bind96, or net/bind97 as of this writing.
334
335This only affects older systems upgrading to 2.8. New 2.8+ installs
336include BIND as a pkgsrc package.

343Instructions on how to obtain and maintain DragonFly source code using git
344are in the development(7) manual page.
d2a0decc
MD
345
346To upgrade a DragonFly system from sources you run the following sequence:
347
348 cd /usr/src
349 make buildworld
350 make buildkernel KERNCONF=<KERNELNAME>
351 make installkernel KERNCONF=<KERNELNAME>
352 make installworld
353
354You will also want to run the 'upgrade' target to upgrade your /etc and the
355rest of your system. The upgrade target is aware of stale files created by
356older DragonFly installations and should delete them automatically.
357
358 make upgrade
359
a700883c
SW
360See the build(7) manual page for further information.
361
d2a0decc
MD
362Once you've done a full build of the world and kernel you can do incremental
363upgrades of either by using the 'quickworld' and 'quickkernel' targets
364instead of 'buildworld' and 'buildkernel'. If you have any problems with
a700883c 365the quick targets, try updating your repo first, and then a full buildworld
d2a0decc 366and buildkernel as shown above, before asking for help.

369+ UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1 +
370+-----------------------------------------------------------------------+
371
372In 2.1 kernel and modules has moved to boot directory. For most cases
373this is handled automatically by 'make upgrade'. A few cases needs manual
374intervention:
375
376 * When installing a kernel without first doing a make buildworld,
377 installworld and upgrade to the same DESTDIR as kernel:
378 make DESTDIR/boot directory and move kernel and modules into this boot
379 directory; also move kernel.old and modules.old.
380 Typical example is vkernel(7), use (no modules used):
381
382 cd /var/vkernel
383 mkdir boot
384 chflags noschg kernel
385 mv kernel kernel.old boot
386 chflags schg boot/kernel
387
388 * When using a boot-only partition, /boot/loader.rc needs to be edited:
389 delete occurrences of '/boot/'.
390 These occurences can normally be deleted in any case, see loader(8).

393+ UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 +
394+-----------------------------------------------------------------------+
395
396In 1.9 major changes to the disk management infrastructure have taken
397place. make upgrade may not catch all of your disk devices in /dev,
398so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
45e80934
MD
399are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
400and MAKEDEV no longer exists.
d2a0decc
MD
401
402The biggest changes in 1.9 are:
403
404(1) That whole-slice devices such as da0s1 no longer share the same device
405 id as partition c devices such as da0s1c.
406
407(2) The whole-disk device (e.g. da0) is full raw access to the disk,
408 with no snooping or reserved sectors. Consequently you cannot run
409 disklabel on this device. Instead you must run disklabel on a
410 whole-slice device.
411
412(3) The 'compatibility' partitions now use slice 0 in the device name,
413 so instead of da0a you must specify da0s0a. Also, as per (1) above,
414 accessing the disklabel for the compatibility partitions must be
415 done via slice 0 (da0s0).
416
417(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
418 and CCD now run through the disk management layer and are assigned
419 real disk management devices. VN and CCD in particular do not usually
420 use a MBR and disklabels must be accessed through the compatibility
421 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
422 don't name it 'ccd0s0' in the config file.
423
424Generally speaking, you have to get used to running fdisk and disklabel on
425the correctly specified device names. A lot of the wiggle, such as running
426disklabel on a partition, has been removed.

435Kerberos IV (eBones) was removed from the tree, please consider moving to
436Kerberos 5 (Heimdal).
437
438> Package Management System
439---------------------------
440
441Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
442management system. The necessary tools to build and maintain packages
443are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
444directories are in your PATH variable.
445
446In order to obtain a reasonably current snapshot of the pkgsrc tree, use
447the tarball from NetBSD:
448
449 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
450 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
451
452This tree can then be kept up to date with cvs update:
453
454 cd /usr/pkgsrc; cvs up
455
456NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
457build and install the pkgsrc bootstrap manually:
458
459 cd /usr/pkgsrc/bootstrap

f419daca 494> Upgrading to DragonFly from FreeBSD

497You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
498FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
499FreeBSD. Note that the DragonFly buildworld target does not try to reuse
500make depend information, it starts from scratch, so no pre-cleaning of the
501object hierarchy is necessary.

520Once you have built DragonFly you have to install it over FreeBSD. Since
521DragonFly does not track changes made by FreeBSD to its include file
522hierarchy and include file pollution can cause all sorts of unexpected
523compilation issues to come up, it is best to wipe your include hierarchy
524prior to installing DragonFly. Note that you should not wipe any installed
525FreeBSD header files or binaries until after you have successfully completed
526the build steps above.

f419daca 534will unconditionally upgrade the /etc files that sysops do not usually
b8cbf045
SW
535mess around with, such as the files in /etc/rc.d. It will also remove any
536obsolete files such as utilities and manpages that have been removed from
537the system since the version you're coming from. If you are unsure we
538recommend that you make a backup of at least your /etc before applying
539this step. Note that DragonFly's RC system is basically RCNG from
540FreeBSD-5, but there are some differences in the contents of the RC files.

542 make upgrade

544NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
545Doing so might leave your system in an unusable state.
546
f419daca 547Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
b8cbf045
SW
548/usr/bin, and /usr/lib, and remove any stale files that you find. Please
549report these files to the DragonFly developers so that they can be added to
550the 'upgrade' target.
