11+-----------------------------------------------------------------------+
12+         UPGRADING DRAGONFLY FROM 4.0 TO LATER VERSIONS                +
13+-----------------------------------------------------------------------+
14
15_KPOSIX_VERSION and P1003_1B OPTIONS REMOVED
16--------------------------------------------
17
18The _KPOSIX_VERSION and P1003_1B kernel options have been changed to
19no-ops. They can be removed from custom kernel configurations.
20
21SOUND SYSTEM UPDATED FROM FreeBSD 11-CURRENT
22--------------------------------------------
23
24Many more sound devices may be detected.
25
26If the default device choosen isn't to your liking, setting the sysctl
27hw.snd.default_unit to a different number will change it.
28
29SCTP SUPPORT DROPPED
30--------------------
31
32Support for the SCTP protocol has been removed.
33
34OLD USB DRIVERS REMOVED
35-----------------------
36
37The old USB stack, along with the kernel config option "device oldusb"
38and the make.conf variable "WANT_OLDUSB" have been removed. This means
39that for custom kernel configuration files which were derived from a
40GENERIC or X86_64_GENERIC file prior to making the usb4bsd stack default,
41various (old USB stack specific) devices will now complain about being
42unknown:
43
44  * oldusb	(obviously)
45  * natausb	(not yet ported to usb4bsd)
46  * rue		(not yet ported to usb4bsd)
47  * ugen	(no longer needed in usb4bsd)
48  * urio	(not yet ported to usb4bsd)
49  * uscanner	(no longer needed in usb4bsd)
50
51They should be removed or commented out in such custom kernel configs.
52
53+-----------------------------------------------------------------------+
54+         UPGRADING DRAGONFLY FROM 3.8 TO LATER VERSIONS                +
55+-----------------------------------------------------------------------+
56
57SMP AND DEVICE_POLLING OPTIONS MADE UNKNOWN
58-------------------------------------------
59
60DEVICE_POLLING was replaced by IFPOLL_ENABLE and the former SMP code is
61the default now (even on single-core systems), both for, like, 21 months.
62We kept the options around as no-ops as a convenience, to allow people
63using the same config for the then current release and the then current
64master. That period is now over, so any configs still having those
65options have to be adjusted.
66
67SYSVIPC SYSCALLS MADE NON-OPTIONAL
68----------------------------------
69
70The code related to the SYSVMSG, SYSVSEM and SYSVSHM kernel options is
71now compiled in by default. The options are no-ops for now.
72
73DEFAULT DRIVER CHANGED FOR LSI "THUNDERBOLT" SERIES RAID CONTROLLERS
74--------------------------------------------------------------------
75
76The default driver for those controllers is now mrsas(4) due to reports
77of file system corruption using the mfi(4) driver. The whole issue (and
78how to deal with potential problems when switching) was explained here:
79
80http://lists.dragonflybsd.org/pipermail/users/2014-July/128703.html
81
82A tunable is provided for letting those controllers still attach via
83the mfi(4) driver, hw.mrsas.mfi_enable (see mrsas(4) manual page).
84
85OLDER NETWORK DRIVERS MOVED TO I386 ONLY
86----------------------------------------
87
88The following drivers have been made i386 only: ed(4), sr(4), ng_sync_ar
89and ng_sync_sr. ed(4) used to be in X86_64_GENERIC, so it has to be
90removed in kernel configs derived from X86_64_GENERIC.
91
92+-----------------------------------------------------------------------+
93+         UPGRADING DRAGONFLY FROM 3.6 TO LATER VERSIONS                +
94+-----------------------------------------------------------------------+
95
96UPDATE FROM MOST RECENT 3.6
97---------------------------
98
99Versions of 3.6 built before June 25th have a bug where installworld might
100crash during installation of the new initrd.  Upgrade to the latest version
101of 3.6 before updating to 3.8 or later.
102
103ATM, IPX, NCP AND NWFS SUPPORT DROPPED
104--------------------------------------
105
106Support for the IPX and NCP network protocols and for mouting NetWare
107file systems has been dropped. Dito for ATM protocol support.
108
109INITRD IMAGES NOW INSTALLED BY DEFAULT
110--------------------------------------
111
112An initial ramdisk image is now installed in /boot/kernel/initrd.img.gz
113
114Older images installed under the file name of initrd.img will be removed
115automatically by the make upgrade process.
116
117USB4BSD IS NOW THE DEFAULT USB STACK
118------------------------------------
119
120To get back to the old stack, put "WANT_OLDUSB=yes" in /etc/make.conf and
121replace "device usb" with "device oldusb" in the kernel configuration.
122
123MORE ISA SUPPORT DROPPED
124------------------------
125
126ISA support has been dropped from the following drivers: adv(4), an(4),
127ar(4), cs(4), digi(4), ed(4), ep(4), ex(4), fe(4), lnc(4), sbni(4),
128si(4), sn(4), and stg(4).
129
130+-----------------------------------------------------------------------+
131+         UPGRADING DRAGONFLY FROM 3.4 TO LATER VERSIONS                +
132+-----------------------------------------------------------------------+
133
134ABI CHANGE
135----------
136
137Installed third-party software (dports) will have to be rebuilt after upgrade,
138or reinstalled from binary packages.
139
140UPDATING FROM 3.4 TO 3.6
141------------------------
142
143This only applies for this specific upgrade due to locale changes; it is
144not needed for upgrades after 3.6.  Please update in this order:
145
146make buildworld
147make buildkernel
148make installworld
149make installkernel
150*reboot*
151make upgrade
152
153See this mailing list post for details:
154http://lists.dragonflybsd.org/pipermail/users/2013-September/090163.html
155
156CYRIX OPTIONS REMOVED
157---------------------
158
159The following Cyrix related options have been removed: CPU_BTB_EN,
160CPU_CYRIX_NO_LOCK, CPU_DIRECT_MAPPED_CACHE, CPU_DISABLE_5X86_LSSER,
161CPU_FASTER_5X86_FPU, CPU_IORT, CPU_LOOP_EN, CPU_RSTK_EN, CPU_SUSP_HLT,
162CYRIX_CACHE_WORKS, and CYRIX_CACHE_REALLY_WORKS
163
164ISA SUPPORT REMOVED FROM RP(4)
165------------------------------
166
167ISA support has been removed from the rp(4) driver. It is now PCI only.
168
169+-----------------------------------------------------------------------+
170+         UPGRADING DRAGONFLY FROM 3.2 TO LATER VERSIONS                +
171+-----------------------------------------------------------------------+
172
173COMPAT_SUNOS OPTION REMOVED
174---------------------------
175
176The COMPAT_SUNOS option has been removed. It was meant to provide binary
177compatibility with SunOS 4.x for the sparc32 port of 4.4BSD.
178
179ISA SOUND CARD SUPPORT REMOVED
180------------------------------
181
182The following modules have been removed (all for ISA sound cards):
183snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko
184
185GCC 4.7
186-------
187
188DragonFly has switched base compilers.  GCC 4.7 is now the default
189compiler and GCC 4.4 is the alternative compiler.  The "NO_GCC47" make
190variable ceases to work now.
191
192Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
193/etc/make.conf to prohibit GCC 4.4 from building.  However, using it is
194highly discouraged.  There are a few packages in pkgsrc that do not build
195with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default.  At
196this time, it is recommended to keep both compilers on the base system.
197
198SMP OPTION REMOVED
199------------------
200
201The SMP kernel option has been made a no-op. All kernels now feature SMP
202support. If you have 'options SMP' in your kernel config, you can as well
203remove it.
204
205DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED
206---------------------------------------------------------------------------
207
208The DEVICE_POLLING kernel option has been made a no-op and it has been
209replaced by IFPOLL_ENABLE.  If you have 'options DEVICE_POLLING' in your
210kernel config, you need to change it to IFPOLL_ENABLE.
211
212Also, the KTR_POLLING kernel option has been removed, so it must be
213removed from kernel configs that have it.
214
215BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED
216---------------------------------------------------
217
218The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA
219cards will no longer be detected.
220
221The same has been done for Stallion multiport serial controllers. stli(4)
222has been completely removed (along with the stlload(8) and stlstty(8)
223utilities) and stl(4) was changed to support only PCI cards. Similarly,
224ISA support was removed from cy(4) too. All these drivers are i386 only.
225
226COMPAT_OLDISA OPTION GONE
227-------------------------
228
229The i386 specific COMPAT_OLDISA kernel option has been removed, since
230nothing needs it anymore.
231
232+-----------------------------------------------------------------------+
233+         UPGRADING DRAGONFLY FROM 3.0 TO LATER VERSIONS                +
234+-----------------------------------------------------------------------+
235
236APIC_IO OPTION REMOVED
237----------------------
238
239The APIC_IO kernel option is no longer accepted after having been without
240effect for a while. The hw.ioapic_enable tunable now serves its purpose.
241If you have 'options APIC_IO' in your kernel config, you'll have to
242remove it.
243
244WATCHDOG_ENABLE & HW_WDOG OPTIONS REMOVED
245-----------------------------------------
246
247The wdog framework is now compiled into our kernels by default, so the
248options are no longer needed.
249
250DOSCMD(1) REMOVED
251-----------------
252
253doscmd(1) has been removed. It was i386 only. The doscmd(1) specific
254NO_X make.conf option was removed too.
255
256GCC 4.7
257-------
258
259GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non-
260default compiler in base (default is still GCC 4.4).
261
262Users who wish to build only GCC 4.4 have to replace NO_GCC41 with
263NO_GCC47 in /etc/make.conf.
264
265USB4BSD
266-------
267
268A new USB stack (from FreeBSD) has been brought in. The following
269modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass,
270usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk,
271and uaudio.
272
273It is not yet the default. To activate it, WANT_USB4BSD=yes has to
274be put in make.conf and device "usb4bsd" (quotes needed) has to
275replace device usb in the kernel config. After that, a full
276build/install/upgrade cycle is needed.
277
278Note that this is experimental and incomplete, but we are interested
279in hearing about issues with it, of course.
280
281ISA SUPPORT REMOVED FROM AIC-6260/6360 DRIVER
282---------------------------------------------
283
284ISA adapter support was dropped from the aic(4) driver.
285
286+-----------------------------------------------------------------------+
287+         UPGRADING DRAGONFLY FROM 2.10 TO LATER VERSIONS               +
288+-----------------------------------------------------------------------+
289
290SEVERAL ISA DRIVERS REMOVED
291---------------------------
292
293The following ISA only drivers have been removed along with a couple of
294associated userland tools:
295
296aha(4)
297asc(4) & sasc(1)
298ctx
299dgb(4)
300el(4)
301gpib
302gsc(4) & sgsc(1)
303ie(4)
304labpc(4)
305le(4)
306mse(4)
307rc(4)
308rdp(4)
309spigot
310tw(4) & xten(1) & xtend(8)
311wl(4) & wlconfig(8)
312wt(4)
313
314Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC
315config and one (aha(4)) is in our X86_64_GENERIC kernel configuration
316file.
317
318If buildkernel complains about any of these drivers, just remove them
319from your kernel configuration.
320
321BINUTILS 2.20
322-------------
323Binutils 2.20 has been removed in favor of Binutils 2.22.  The accepted
324values of BINUTILSVERS are now binutils221 and binutils222 (default).
325
326BUILDWORLD/-KERNEL PARALLELIZATION WORK
327---------------------------------------
328Due to changes in the way we build with more than one make job, you
329will have to update install(1) and mkdir(1) prior to buildworld if you
330want to build with 'make -j':
331
332cd /usr/src/usr.bin/xinstall; make; make install; make clean
333cd /usr/src/bin/mkdir; make; make install; make clean
334
335DMA(8) UPGRADE
336--------------
337dma(8) has been upgraded to v0.7 which no longer supports the
338/etc/dma/virtusertable. Some of its functionality has been replaced
339with the MASQUERADE keyword and the EMAIL environment variable (see
340the dma(8) manual page).
341
342+-----------------------------------------------------------------------+
343+         UPGRADING DRAGONFLY FROM 2.8 TO LATER VERSIONS                +
344+-----------------------------------------------------------------------+
345
346GCC 4.4 & BINUTILS 2.21
347-----------------------
348
349GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has
350been made DragonFly's default Binutils.
351
352That means that any settings that set CCVER to 'gcc44' are not needed
353anymore. Instead, CCVER can be set to 'gcc41' to go back to using
354GCC 4.1.
355
356It also means that 'binutils221' as a value for BINUTILSVER has no
357effect anymore. 2.17 has been removed and 'binutils220' is available
358as an option.
359
360The NO_GCC44 option has been removed and will not affect the build
361anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from
362building in a similar fashion.
363
364Note that you must do a full buildworld/buildkernel for upgrading.
365
366pkg_radd settings
367-----------------
368
369The config file for pkg_radd has moved from /etc/settings.conf to
370/etc/pkg_radd.conf.  Save the contents of settings.conf before upgrading
371if this is needed.  This warning only applies if /etc/settings.conf
372exists.  pkg_radd will continue to work with defaults.
373
374+-----------------------------------------------------------------------+
375+         20100927							+
376+         UPGRADING DRAGONFLY FROM 2.6 to 2.8 or HEAD			+
377+-----------------------------------------------------------------------+
378
379OpenSSL
380--------
381
382OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto.
383This shouldn't break any 3rd-party software, but you'll need to recompile your
3843rd-party software if you want it to link against the new version of OpenSSL.
385
386Loader
387-------
388
389A new loader (dloader) has been added which better handles booting from
390multiple kernel/module versions.
391
392To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below)
393
394	cd /usr/src
395	make buildworld
396	make installworld
397	make upgrade
398	make buildkernel KERNCONF=<KERNELNAME>
399	make installkernel KERNCONF=<KERNELNAME>
400
401Note that you must installworld and run the 'upgrade' target before
402installing the new kernel.
403
404BIND
405-----
406
407BIND has been removed from the base system.  The ldns and drill tools have
408been added for basic functionality.  Use 'drill' where you would normally
409use nslookup or dig, or install BIND from pkgsrc.  It's available as
410net/bind95, net/bind96, or net/bind97 as of this writing.
411
412This only affects older systems upgrading to 2.8.  New 2.8+ installs
413include BIND as a pkgsrc package.
414
415+-----------------------------------------------------------------------+
416+         UPGRADING DRAGONFLY ON AN EXISTING DRAGONFLY SYSTEM		+
417+				GENERAL					+
418+-----------------------------------------------------------------------+
419
420Instructions on how to obtain and maintain DragonFly source code using git
421are in the development(7) manual page.
422
423To upgrade a DragonFly system from sources you run the following sequence:
424
425	cd /usr/src
426	make buildworld
427	make buildkernel KERNCONF=<KERNELNAME>
428	make installkernel KERNCONF=<KERNELNAME>
429	make installworld
430
431You will also want to run the 'upgrade' target to upgrade your /etc and the
432rest of your system.  The upgrade target is aware of stale files created by
433older DragonFly installations and should delete them automatically.
434
435	make upgrade
436
437See the build(7) manual page for further information.
438
439Once you've done a full build of the world and kernel you can do incremental
440upgrades of either by using the 'quickworld' and 'quickkernel' targets
441instead of 'buildworld' and 'buildkernel'.  If you have any problems with
442the quick targets, try updating your repo first, and then a full buildworld
443and buildkernel as shown above, before asking for help.
444
445+-----------------------------------------------------------------------+
446+         UPGRADING FROM DRAGONFLY <= 2.0 TO DRAGONFLY >= 2.1		+
447+-----------------------------------------------------------------------+
448
449In 2.1 kernel and modules has moved to boot directory.  For most cases
450this is handled automatically by 'make upgrade'.  A few cases needs manual
451intervention:
452
453 * When installing a kernel without first doing a make buildworld,
454   installworld and upgrade to the same DESTDIR as kernel:
455   make DESTDIR/boot directory and move kernel and modules into this boot
456   directory; also move kernel.old and modules.old.
457   Typical example is vkernel(7), use (no modules used):
458
459	cd /var/vkernel
460	mkdir boot
461	chflags noschg kernel
462	mv kernel kernel.old boot
463	chflags schg boot/kernel
464
465 * When using a boot-only partition, /boot/loader.rc needs to be edited:
466   delete occurrences of '/boot/'.
467   These occurences can normally be deleted in any case, see loader(8).
468
469+-----------------------------------------------------------------------+
470+         UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9		+
471+-----------------------------------------------------------------------+
472
473In 1.9 major changes to the disk management infrastructure have taken
474place.  make upgrade may not catch all of your disk devices in /dev,
475so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
476are all of your disk devices.  HOWEVER, from late 2.3 on we run devfs
477and MAKEDEV no longer exists.
478
479The biggest changes in 1.9 are:
480
481(1) That whole-slice devices such as da0s1 no longer share the same device
482    id as partition c devices such as da0s1c.
483
484(2) The whole-disk device (e.g. da0) is full raw access to the disk,
485    with no snooping or reserved sectors.  Consequently you cannot run
486    disklabel on this device.  Instead you must run disklabel on a
487    whole-slice device.
488
489(3) The 'compatibility' partitions now use slice 0 in the device name,
490    so instead of da0a you must specify da0s0a.  Also, as per (1) above,
491    accessing the disklabel for the compatibility partitions must be
492    done via slice 0 (da0s0).
493
494(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
495    and CCD now run through the disk management layer and are assigned
496    real disk management devices.   VN and CCD in particular do not usually
497    use a MBR and disklabels must be accessed through the compatibility
498    slice 0.  Your /etc/ccd.conf file still specifies 'ccd0', though, you
499    don't name it 'ccd0s0' in the config file.
500
501Generally speaking, you have to get used to running fdisk and disklabel on
502the correctly specified device names.  A lot of the wiggle, such as running
503disklabel on a partition, has been removed.

507+-----------------------------------------------------------------------+
508
509> Kerberos IV
510-------------
511
512Kerberos IV (eBones) was removed from the tree, please consider moving to
513Kerberos 5 (Heimdal).
514
515> Package Management System
516---------------------------
517
518Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
519management system.  The necessary tools to build and maintain packages
520are provided in /usr/pkg/bin and /usr/pkg/sbin.  Make sure that these
521directories are in your PATH variable.
522
523In order to obtain a reasonably current snapshot of the pkgsrc tree, use
524the tarball from NetBSD:
525
526	fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
527	cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
528
529This tree can then be kept up to date with cvs update:
530
531	cd /usr/pkgsrc; cvs up
532
533NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
534build and install the pkgsrc bootstrap manually:
535
536	cd /usr/pkgsrc/bootstrap
537	./bootstrap --pkgdbdir /var/db/pkg --prefix /usr/pkg

544
545The compatibility shims for the build environment have been removed, you
546have to update to DragonFly 1.2 release branch first.
547
548The default PAM configuration has moved from /etc/pam.conf to /etc/pam.d/.
549The existing configuration can be converted using /etc/pam.d/convert.sh.
550Entries in /etc/pam.d/ override entries in /etc/pam.conf. In addition
551the pam_skey.so module was retired, you have to remove it manually from
552your configuration, when you convert it.

571> Upgrading to DragonFly from FreeBSD
572---------------------
573
574You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
575FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
576FreeBSD.  Note that the DragonFly buildworld target does not try to reuse
577make depend information, it starts from scratch, so no pre-cleaning of the
578object hierarchy is necessary.
579
580	# get the CVS repository (it is placed in /home/dcvs, 500MB).
581	# Please use the -h option and a mirror site to pull the
582	# initial repository, but feel free to use the main repository
583	# machine to pull updates.
584	cvsup /usr/share/examples/cvsup/DragonFly-cvs-supfile
585	# install the source from the CVS hierarchy (remove preexisting
586	# FreeBSD src first) (500MB)
587	cd /usr
588	rm -rf src
589	cvs -R -d /home/dcvs checkout -P src
590
591	# build it (500MB used in /usr/obj)
592	#
593	cd /usr/src
594	make buildworld
595	make buildkernel KERNCONF=<KERNELNAME>
596
597Once you have built DragonFly you have to install it over FreeBSD.  Since
598DragonFly does not track changes made by FreeBSD to its include file
599hierarchy and include file pollution can cause all sorts of unexpected
600compilation issues to come up, it is best to wipe your include hierarchy
601prior to installing DragonFly.  Note that you should not wipe any installed
602FreeBSD header files or binaries until after you have successfully completed
603the build steps above.
604
605	rm -rf /usr/include
606	mkdir /usr/include
607	make installkernel KERNCONF=<KERNELNAME>
608	make installworld
609
610Then you need to upgrade your system.  DragonFly's 'make upgrade' target
611will unconditionally upgrade the /etc files that sysops do not usually
612mess around with, such as the files in /etc/rc.d.  It will also remove any
613obsolete files such as utilities and manpages that have been removed from
614the system since the version you're coming from.  If you are unsure we
615recommend that you make a backup of at least your /etc before applying
616this step.  Note that DragonFly's RC system is basically RCNG from
617FreeBSD-5, but there are some differences in the contents of the RC files.
618
619	make upgrade
620
621NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
622Doing so might leave your system in an unusable state.
623
624Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
625/usr/bin, and /usr/lib, and remove any stale files that you find.  Please
626report these files to the DragonFly developers so that they can be added to
627the 'upgrade' target.
