15ISA SOUND CARD SUPPORT REMOVED
16------------------------------
17
18The following modules have been removed (all for ISA sound cards):
19snd_ad1816.ko, snd_ess.ko, snd_mss.ko, snd_sb8.ko, snd_sb16.ko, snd_sbc.ko

21GCC 4.7
22-------
23
24DragonFly has switched base compilers. GCC 4.7 is now the default
25compiler and GCC 4.4 is the alternative compiler. The "NO_GCC47" make
26variable ceases to work now.
27
28Users who wish to build only GCC 4.7 have to use NO_GCC44 in the
29/etc/make.conf to prohibit GCC 4.4 from building. However, using it is
30highly discouraged. There are a few packages in pkgsrc that do not build
31with GCC 4.7 and the new "DPorts" system uses GCC 4.4 by default. At
32this time, it is recommended to keep both compilers on the base system.

34SMP OPTION REMOVED
35------------------
36
37The SMP kernel option has been made a no-op. All kernels now feature SMP
38support. If you have 'options SMP' in your kernel config, you can as well
39remove it.

41DEVICE_POLLING OPTION REPLACED BY IFPOLL_ENABLE OPTION, KTR_POLLING REMOVED
42---------------------------------------------------------------------------
640dc18f
SZ
43
44The DEVICE_POLLING kernel option has been made a no-op and it has been
45replaced by IFPOLL_ENABLE. If you have 'options DEVICE_POLLING' in your
46kernel config, you need to change it to IFPOLL_ENABLE.
47
1c297ed0
SW
48Also, the KTR_POLLING kernel option has been removed, so it must be
49removed from kernel configs that have it.

51BUSLOGIC, CYCLADES AND STALLION ISA SUPPORT REMOVED
52---------------------------------------------------

53
54The bt(4) driver for Buslogic SCSI adapters has been made PCI only. ISA
55cards will no longer be detected.
56
e6f626a1
SW
57The same has been done for Stallion multiport serial controllers. stli(4)
58has been completely removed (along with the stlload(8) and stlstty(8)
558b0a0b
SW
59utilities) and stl(4) was changed to support only PCI cards. Similarly,
60ISA support was removed from cy(4) too. All these drivers are i386 only.

73----------------------
74
75The APIC_IO kernel option is no longer accepted after having been without
76effect for a while. The hw.ioapic_enable tunable now serves its purpose.
77If you have 'options APIC_IO' in your kernel config, you'll have to
78remove it.

92GCC 4.7
93-------
94
95GCC 4.7 has been brought in and replaces GCC 4.1 as DragonFly's non-
96default compiler in base (default is still GCC 4.4).
97
98Users who wish to build only GCC 4.4 have to replace NO_GCC41 with
99NO_GCC47 in /etc/make.conf.

101USB4BSD
102-------
103
104A new USB stack (from FreeBSD) has been brought in. The following
105modules have been ported so far: usb, uhci, ohci, ehci, xhci, umass,
106usfs, uether, if_axe, if_udav, ukbd, ums, uep, uhid, usb_quirk,
107and uaudio.
108
109It is not yet the default. To activate it, WANT_USB4BSD=yes has to
c7200221
SW
110be put in make.conf and device "usb4bsd" (quotes needed) has to
111replace device usb in the kernel config. After that, a full
112build/install/upgrade cycle is needed.

126SEVERAL ISA DRIVERS REMOVED
127---------------------------
128
129The following ISA only drivers have been removed along with a couple of
130associated userland tools:
131
132aha(4)
133asc(4) & sasc(1)
134ctx
135dgb(4)

148wt(4)
149
150Note that two of these drivers (aha(4) and ie(4)) are in our GENERIC
151config and one (aha(4)) is in our X86_64_GENERIC kernel configuration
152file.
153
154If buildkernel complains about any of these drivers, just remove them
155from your kernel configuration.

163---------------------------------------
164Due to changes in the way we build with more than one make job, you
165will have to update install(1) and mkdir(1) prior to buildworld if you
166want to build with 'make -j':
167
168cd /usr/src/usr.bin/xinstall; make; make install; make clean

175with the MASQUERADE keyword and the EMAIL environment variable (see
176the dma(8) manual page).

b1242318

185GCC 4.4 has been made DragonFly's default compiler and Binutils 2.21 has
186been made DragonFly's default Binutils.
30c91f0c
SW
187
188That means that any settings that set CCVER to 'gcc44' are not needed
189anymore. Instead, CCVER can be set to 'gcc41' to go back to using
190GCC 4.1.
191
b1242318
SW
192It also means that 'binutils221' as a value for BINUTILSVER has no
193effect anymore. 2.17 has been removed and 'binutils220' is available
194as an option.
195
5738210d 196The NO_GCC44 option has been removed and will not affect the build
30c91f0c
SW
197anymore. There is now a NO_GCC41 option that will prevent GCC 4.1 from
198building in a similar fashion.
199

217
218OpenSSL has been upgraded, and SHLIB_MAJOR was bumped for libssh and libcrypto.

JT
225A new loader (dloader) has been added which better handles booting from
226multiple kernel/module versions.
227
228To upgrade (Only for this upgrade, for post 2.8 upgrades see GENERAL below)
229
230 cd /usr/src
231 make buildworld
232 make installworld
233 make upgrade
234 make buildkernel KERNCONF=<KERNELNAME>
235 make installkernel KERNCONF=<KERNELNAME>

237Note that you must installworld and run the 'upgrade' target before
238installing the new kernel.

242
243BIND has been removed from the base system. The ldns and drill tools have
244been added for basic functionality. Use 'drill' where you would normally
245use nslookup or dig, or install BIND from pkgsrc. It's available as
246net/bind95, net/bind96, or net/bind97 as of this writing.
247
248This only affects older systems upgrading to 2.8. New 2.8+ installs
249include BIND as a pkgsrc package.

256Instructions on how to obtain and maintain DragonFly source code using git
257are in the development(7) manual page.
d2a0decc
MD
258
259To upgrade a DragonFly system from sources you run the following sequence:
260
261 cd /usr/src
262 make buildworld
263 make buildkernel KERNCONF=<KERNELNAME>
264 make installkernel KERNCONF=<KERNELNAME>
265 make installworld
266
267You will also want to run the 'upgrade' target to upgrade your /etc and the
268rest of your system. The upgrade target is aware of stale files created by
269older DragonFly installations and should delete them automatically.
270
271 make upgrade
272
a700883c
SW
273See the build(7) manual page for further information.
274
d2a0decc
MD
275Once you've done a full build of the world and kernel you can do incremental
276upgrades of either by using the 'quickworld' and 'quickkernel' targets
277instead of 'buildworld' and 'buildkernel'. If you have any problems with
a700883c 278the quick targets, try updating your repo first, and then a full buildworld
d2a0decc 279and buildkernel as shown above, before asking for help.

283+-----------------------------------------------------------------------+
284
285In 2.1 kernel and modules has moved to boot directory. For most cases
286this is handled automatically by 'make upgrade'. A few cases needs manual
287intervention:
288
289 * When installing a kernel without first doing a make buildworld,
290 installworld and upgrade to the same DESTDIR as kernel:
291 make DESTDIR/boot directory and move kernel and modules into this boot
292 directory; also move kernel.old and modules.old.
293 Typical example is vkernel(7), use (no modules used):
294
295 cd /var/vkernel
296 mkdir boot
297 chflags noschg kernel
298 mv kernel kernel.old boot
299 chflags schg boot/kernel
300
301 * When using a boot-only partition, /boot/loader.rc needs to be edited:
302 delete occurrences of '/boot/'.
303 These occurences can normally be deleted in any case, see loader(8).

306+ UPGRADING FROM DRAGONFLY <= 1.8 TO DRAGONFLY >= 1.9 +
307+-----------------------------------------------------------------------+
308
309In 1.9 major changes to the disk management infrastructure have taken
310place. make upgrade may not catch all of your disk devices in /dev,
311so after upgrading be sure to cd /dev; ./MAKEDEV <blah> where <blah>
45e80934
MD
312are all of your disk devices. HOWEVER, from late 2.3 on we run devfs
313and MAKEDEV no longer exists.
d2a0decc
MD
314
315The biggest changes in 1.9 are:
316
317(1) That whole-slice devices such as da0s1 no longer share the same device
318 id as partition c devices such as da0s1c.
319
320(2) The whole-disk device (e.g. da0) is full raw access to the disk,
321 with no snooping or reserved sectors. Consequently you cannot run
322 disklabel on this device. Instead you must run disklabel on a
323 whole-slice device.
324
325(3) The 'compatibility' partitions now use slice 0 in the device name,
326 so instead of da0a you must specify da0s0a. Also, as per (1) above,
327 accessing the disklabel for the compatibility partitions must be
328 done via slice 0 (da0s0).
329
330(4) Many device drivers that used to fake up labels, such as CD, ACD, VN,
331 and CCD now run through the disk management layer and are assigned
332 real disk management devices. VN and CCD in particular do not usually
333 use a MBR and disklabels must be accessed through the compatibility
334 slice 0. Your /etc/ccd.conf file still specifies 'ccd0', though, you
335 don't name it 'ccd0s0' in the config file.
336
337Generally speaking, you have to get used to running fdisk and disklabel on
338the correctly specified device names. A lot of the wiggle, such as running
339disklabel on a partition, has been removed.

348Kerberos IV (eBones) was removed from the tree, please consider moving to
349Kerberos 5 (Heimdal).
350
351> Package Management System
352---------------------------
353
354Starting with the 1.4 release, DragonFly uses NetBSD's pkgsrc package
355management system. The necessary tools to build and maintain packages
356are provided in /usr/pkg/bin and /usr/pkg/sbin. Make sure that these
357directories are in your PATH variable.
358
359In order to obtain a reasonably current snapshot of the pkgsrc tree, use
360the tarball from NetBSD:
361
362 fetch -o /tmp/pkgsrc.tar.gz ftp://ftp.NetBSD.org/pub/NetBSD/packages/pkgsrc.tar.gz
363 cd /usr; tar -xzf /tmp/pkgsrc.tar.gz; chown -R root:wheel pkgsrc
364
365This tree can then be kept up to date with cvs update:
366
367 cd /usr/pkgsrc; cvs up
368
369NOTE! If you upgraded from a pre-1.4 system to 1.4 or later, you need to
370build and install the pkgsrc bootstrap manually:
371
372 cd /usr/pkgsrc/bootstrap

410You can build the DragonFly world and DragonFly kernels on a FreeBSD-4.x or
411FreeBSD-5.x machine and then install DragonFly over FreeBSD, replacing
412FreeBSD. Note that the DragonFly buildworld target does not try to reuse
413make depend information, it starts from scratch, so no pre-cleaning of the
414object hierarchy is necessary.

433Once you have built DragonFly you have to install it over FreeBSD. Since
434DragonFly does not track changes made by FreeBSD to its include file
435hierarchy and include file pollution can cause all sorts of unexpected
436compilation issues to come up, it is best to wipe your include hierarchy
437prior to installing DragonFly. Note that you should not wipe any installed
438FreeBSD header files or binaries until after you have successfully completed
439the build steps above.

443 make installkernel KERNCONF=<KERNELNAME>
444 make installworld
fb12f484 445
b8cbf045 446Then you need to upgrade your system. DragonFly's 'make upgrade' target
f419daca 447will unconditionally upgrade the /etc files that sysops do not usually
b8cbf045
SW
448mess around with, such as the files in /etc/rc.d. It will also remove any
449obsolete files such as utilities and manpages that have been removed from
450the system since the version you're coming from. If you are unsure we
451recommend that you make a backup of at least your /etc before applying
452this step. Note that DragonFly's RC system is basically RCNG from
453FreeBSD-5, but there are some differences in the contents of the RC files.

454
455 make upgrade
456
b8cbf045
SW
457NOTE! Never do a 'make upgrade' before 'make installworld' has been run.
458Doing so might leave your system in an unusable state.
459
f419daca 460Finally we recommend that you do an 'ls -lta BLAH' for /bin, /sbin, /usr/bin,
b8cbf045
SW
461/usr/bin, and /usr/lib, and remove any stale files that you find. Please
462report these files to the DragonFly developers so that they can be added to
463the 'upgrade' target.
