1 # $NetBSD: BRANCHES,v 1.157 2007/03/01 15:13:15 yamt Exp $ 2 # 3 # This file contains a list of branches that exist in the NetBSD CVS 4 # tree and their current state. 5 # 6 # This list is necessarily incomplete. 7 # 8 # Within reason, developers may create branch and version tags at any 9 # time for any purpose. To avoid name collisions, private tags should 10 # have names which begin with the developer's NetBSD login name 11 # followed by a - or _ character (e.g., thorpej_scsipi, 12 # thorpej-signal) 13 # 14 # Any branch or version tag not listed here should be assumed to be 15 # private to the developer who created it. It is inappropriate for 16 # anyone other than that developer to commit, move tags, or otherwise 17 # modify the contents of the branch. 18 # 19 # Please update this file when a new branch is ready for consumption 20 # by folks other than the maintainer, or when the use or status of an 21 # existing branch changes significantly. 22 # 23 # Format: 24 # Branch: name of branch 25 # Description: Purpose and intention of the branch 26 # Status: Active/Terminated/Dormant 27 # Start Date: date first instantiated 28 # End Date: date it was Terminated/made_Dormant, if any 29 # Base Tag: netbsd-1-5-base, etc. 30 # Maintainer: Somebody to blame. 31 # Scope: Portion of the tree covered. 32 # Notes: Various other info, perhaps explanation of special tags, 33 # who-may-commit policies, etc. 34 # 35 # There are four sections to this file: 36 # Release branches 37 # Individual developers' branches (Active/Dormant) 38 # Individual developers' branches (Terminated), and 39 # other 40 # 41 # Entries within each section should be alphabetized. 42 # 43 44 45 # Release branches: 46 47 Branch: comdex-fall-1999 48 Description: Special release branch for pre-1.5 release at 49 Fall 1999 COMDEX. 50 Status: Terminated 51 Start Date: 52 End Date: 53 Base Tag: comdex-fall-1999-base 54 Maintainer: ? 55 Scope: Entire tree. 56 Notes: 57 58 Branch: netbsd-0-9 59 Description: The NetBSD 0.9 release branch 60 Status: Terminated 61 Start Date: 62 End Date: 63 Base Tag: netbsd-0-9-base 64 Maintainer: Release Engineering <releng (a] NetBSD.org> 65 Scope: Entire tree. 66 Notes: Subsidiary tags of: netbsd-0-9-ALPHA, netbsd-0-9-ALPHA2, 67 netbsd-0-9-BETA, netbsd-0-9-RELEASE. 68 Commits restricted to release engineering. 69 70 Branch: netbsd-1-0 71 Description: The NetBSD 1.0 release branch 72 Status: Terminated 73 Start Date: 74 End Date: 75 Base Tag: netbsd-1-0-base 76 Maintainer: Release Engineering <releng (a] NetBSD.org> 77 Scope: Entire tree. 78 Notes: 79 Commits restricted to release engineering. 80 81 Branch: netbsd-1-1 82 Description: The NetBSD 1.1 release branch 83 Status: Terminated 84 Start Date: 85 End Date: 86 Base Tag: netbsd-1-1-base 87 Maintainer: Release Engineering <releng (a] NetBSD.org> 88 Scope: Entire tree. 89 Notes: 90 Commits restricted to release engineering. 91 92 Branch: netbsd-1-2 93 Description: The NetBSD 1.2 release branch 94 Status: Terminated 95 Start Date: 96 End Date: 97 Base Tag: netbsd-1-2-base 98 Maintainer: Release Engineering <releng (a] NetBSD.org> 99 Scope: Entire tree. 100 Notes: 101 Commits restricted to release engineering. 102 103 Branch: netbsd-1-3 104 Description: The NetBSD 1.3 release branch 105 Status: Terminated 106 Start Date: 107 End Date: 108 Base Tag: netbsd-1-3-base 109 Maintainer: Release Engineering <releng (a] NetBSD.org> 110 Scope: Entire tree. 111 Notes: 112 Commits restricted to release engineering. 113 114 Branch: netbsd-1-4 115 Description: The NetBSD 1.4 release branch 116 Status: Terminated 117 Start Date: 1 Apr 2000 118 End Date: 119 Base Tag: netbsd-1-4-base 120 Maintainer: 1.4 Release Engineering <releng-1-4 (a] NetBSD.org> 121 Scope: Entire tree. 122 Notes: 123 Commits restricted to release engineering. 124 125 Branch: netbsd-1-5 126 Description: The NetBSD 1.5 release branch 127 Status: Terminated 128 Start Date: 20 Jun 2000 129 End Date: 26 Jan 2005 130 Base Tag: netbsd-1-5-base 131 Maintainer: 1.5 Release Engineering <releng-1-5 (a] NetBSD.org> 132 Scope: Entire tree. 133 Notes: 134 Commits restricted to release engineering. 135 136 Branch: netbsd-1-6 137 Description: The NetBSD 1.6 release branch 138 Status: Terminated 139 Start Date: 22 May 2002 140 End Date: 141 Base Tag: netbsd-1-6-base 142 Maintainer: 1.6 Release Engineering <releng-1-6 (a] NetBSD.org> 143 Scope: Entire tree. 144 Notes: 145 Commits restricted to Release Engineering. 146 147 Branch: netbsd-2 148 Description: The NetBSD 2 release branch 149 Status: Active 150 Start Date: 23 Dec 2004 151 End Date: 152 Base Tag: netbsd-2-base 153 Maintainer: 2 Release Engineering <releng-2 (a] NetBSD.org> 154 Scope: Entire tree.

It is necessary 234 for the newlock branch, making the scheduler SMP friendly, 235 adding real-time scheduler extensions, and reducing the 236 number of code paths for LWP and proc switching. 237 238 Branch: gmcgarry_ucred 239 Description: Integrate and encapsulate user credentials 240 Status: Dormant 241 Start Date: 18 December 2002 242 End Date: 243 Base Tag: gmcgarry_ucred_base 244 Maintainer: Gregory McGarry <gmcgarry (a] NetBSD.org> 245 Scope: kernel 246 Notes: merge pcred and ucred and poolify 247 248 Branch: kame 249 Description: KAME Project 250 Status: Dormant 251 Start Date: 28 Jun 1999 252 End Date: 253 Base Tag: 254 Maintainer: Jun-ichiro itojun Hagino <itojun (a] NetBSD.org> 255 Scope: kernel 256 Notes: http://www.kame.net 257 Used for "reference" purposes for early part of KAME 258 integration effort. The branch is not actively used, as I 259 (itojun) use patch(1) and diff(1) for the KAME syncs. 260 261 Branch: kent-audio2 262 Description: In-kernel audio mixer 263 Status: Active 264 Start Date: Sun Jan 16 2005 265 End Date: 266 Base Tag: kent-audio2-base 267 Maintainer: TAMURA Kent <kent (a] NetBSD.org> 268 Scope: kernel (audio device drivers) 269 Notes: http://mail-index.netbsd.org/tech-kern/2004/12/03/0007.html 270 Please consult with the maintainer before committing 271 to this branch. 272 This branch is not expected to be compilable yet. 273 274 Branch: matt-timespec 275 Description: Convert the kernel to struct timespec as its primary time 276 storage mechanism. 277 Status: Active 278 Start Date: 2005-02-19 279 End Date: 280 Base Tag: 281 Maintainer: Matt Thomas <matt (a] NetBSD.org> 282 Scope: kernel 283 Notes: 284 285 Branch: newlock 286 Description: New locking primitives, based on Solaris's 287 Status: Terminated 288 Start Date: March 9, 2002 289 End Date: Febuary 12, 2007 290 Base Tag: newlock-base 291 Maintainer: Jason R.

Goals: 309 - Implement new locking primitives on most-used ports. 310 - Minor locking improvements. 311 - Remove spinlockmgr(). 312 313 Branch: pkgviews 314 Description: package views, enabling multiple conflicting packages to co-exist 315 Status: Active 316 Start Date: 22 July 2002 317 End Date: 318 Base Tag: pkgviews 319 Maintainer: Alistair Crooks <agc (a] NetBSD.org> 320 Scope: pkgsrc, basesrc/usr.sbin/pkg_install 321 Notes: A more flexible infrastructure for third-party packages by 322 allowing multiple conflicting packages and versions to co-exist 323 within the same tree 324 325 Branch: rpaulo-netinet-merge-pcb 326 Description: merge in6pcb with inpcb 327 Status: Dormant 328 Start Date: Wed Feb 01 2006 329 End Date: 330 Base Tag: rpaulo-netinet-merge-pcb-base 331 Maintainer: Rui Paulo <rpaulo (a] NetBSD.org> 332 Scope: src/sys 333 Notes: No longer active due to the lack of time. If you plan to 334 continue this branch, sys/netinet/in_pcb.h already contains 335 the proposed structure layout (which was roughly discussed 336 in the tech-net mailing list). 337 I also defined INP_*() macros to mimicate FreeBSD's inpcb 338 locking style, but currently they do nothing and are not 339 yet called at the correct places (needs discussion about 340 kernel fine-grained locking). 341 To continue this branch, one needs to read all the relevant 342 inpcb/in6pcb source files and change the function names, 343 structure names, structure fileds according to the new 344 layout (in6pcb is gone). 345 Don't try to build a kernel from this branch because it won't 346 work. The missing pieces required to do a complete build 347 were not committed because they were incomplete and generated 348 panics. 349 You shouldn't need to worry about KAME syncs because 350 they did most of them by now. 351 After the work is done, you are required to test the branch 352 (before the merge to -current) with an interop IPv6 test. 353 More info at: http://www.tahi.org/ 354 355 Branch: rtr-xorg-branch 356 Description: xorg & static build alterations to src/x11 357 Status: Active 358 Start Date: Nov 15 2004 359 End Date: 360 Base tag: rtr-xorg-branch-base 361 Maintainer: Tyler R.

In terms of UBC, the primary cache for 860 file data is the VM cache, which needs to operate 861 in terms of VM pages. As no existing device has native 862 pages the same size as our VM pages, there already is 863 a mapping going on between the VM system and the 864 underlying blocks. So it would be easier and cleaner 865 to adjust that to deal w/ different block sizes. 866 Also with UBC, all i/o is in terms of bytes at an offset 867 with a certain length, so the exact block size isn't a big 868 deal. 869 870 Any other wrstuden-devbsize tag may (and should) go away. 871 872 Branch: yamt-km, yamt-km-doc 873 Description: simplify/improve kernel memory management and bootstrap 874 Status: Terminated; merged to -current 875 Start Date: Tue Jan 25 2005 876 End Date: Fri Apr 1 2005 877 Base Tag: yamt-km-base{,2,3,4}, yamt-km-doc-base 878 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 879 Scope: yamt-km: src/sys 880 yamt-km-doc: src/share/man/man9/uvm.9 881 Notes: http://mail-index.NetBSD.org/tech-kern/2004/12/25/0005.html 882 883 the followings are per-port status. 884 (account names mean "tested by".) 885 886 works enough to go to multiuser: 887 alpha, i386, xen (yamt@) 888 pc532 (simonb@) 889 alpha, i386, mac68k, macppc, pmax, shark, 890 sparc, sparc64, sun3, x68k (chs@) 891 cobalt, dreamcast, hp300, news68k, newsmips, 892 sun3x (tsutsui@) 893 amiga (mhitch@) 894 cats, hp700 (skrll@) 895 xen (bouyer@) 896 897 known to have the same problem as trunk: 898 vax (chs@, stuck while running kvm_mkdb) 899 900 known to have a problem: 901 luna68k (and, if any, other m68k ports which use TTR) 902 needs to be revisited. 903 -> for luna68k, although not tested, 904 Sysmap has been moved to avoid kva conflict with 905 I/O ranges. 906 907 buildable: 908 src/sys/arch/acorn26/conf/GENERIC 909 src/sys/arch/acorn32/conf/GENERIC 910 src/sys/arch/algor/conf/P6032 911 src/sys/arch/alpha/conf/GENERIC 912 src/sys/arch/alpha/conf/GENERIC.MP 913 src/sys/arch/amd64/conf/GENERIC 914 src/sys/arch/amd64/conf/GENERIC.MP 915 src/sys/arch/amiga/conf/GENERIC 916 src/sys/arch/arc/conf/GENERIC 917 src/sys/arch/atari/conf/MILAN-PCIIDE 918 src/sys/arch/bebox/conf/GENERIC 919 src/sys/arch/cats/conf/GENERIC 920 src/sys/arch/cesfic/conf/GENERIC 921 src/sys/arch/cobalt/conf/GENERIC 922 src/sys/arch/dreamcast/conf/GENERIC 923 src/sys/arch/evbarm/conf/TS7200 924 src/sys/arch/evbppc/conf/WALNUT 925 src/sys/arch/evbsh3/conf/COMPUTEXEVB 926 src/sys/arch/evbsh5/conf/CAYMAN64 927 src/sys/arch/hp300/conf/GENERIC 928 src/sys/arch/hp700/conf/GENERIC 929 src/sys/arch/hpcarm/conf/JORNADA728 930 src/sys/arch/hpcmips/conf/GENERIC 931 src/sys/arch/hpcsh/conf/GENERIC 932 src/sys/arch/hpcsh/conf/HPW650PA 933 src/sys/arch/i386/conf/GENERIC 934 src/sys/arch/i386/conf/GENERIC.MP 935 src/sys/arch/i386/conf/XEN0 936 src/sys/arch/i386/conf/XENU 937 src/sys/arch/ibmnws/conf/GENERIC 938 src/sys/arch/iyonix/conf/GENERIC 939 src/sys/arch/luna68k/conf/GENERIC 940 src/sys/arch/mac68k/conf/GENERIC 941 src/sys/arch/macppc/conf/GENERIC 942 src/sys/arch/macppc/conf/GENERIC.MP 943 src/sys/arch/mipsco/conf/GENERIC 944 src/sys/arch/mmeye/conf/GENERIC 945 src/sys/arch/mvme68k/conf/GENERIC 946 src/sys/arch/netwinder/conf/GENERIC 947 src/sys/arch/news68k/conf/GENERIC 948 src/sys/arch/newsmips/conf/GENERIC 949 src/sys/arch/next68k/conf/GENERIC 950 src/sys/arch/ofppc/conf/GENERIC 951 src/sys/arch/pc532/conf/GENERIC 952 src/sys/arch/pmax/conf/GENERIC 953 src/sys/arch/prep/conf/GENERIC 954 src/sys/arch/sandpoint/conf/GENERIC 955 src/sys/arch/sbmips/conf/GENERIC 956 src/sys/arch/sgimips/conf/GENERIC32_IP3x 957 src/sys/arch/shark/conf/GENERIC 958 src/sys/arch/sparc/conf/GENERIC 959 src/sys/arch/sparc/conf/GENERIC.MP 960 src/sys/arch/sparc64/conf/GENERIC 961 src/sys/arch/sparc64/conf/GENERIC.MP 962 src/sys/arch/sun2/conf/GENERIC 963 src/sys/arch/sun3/conf/GENERIC 964 src/sys/arch/vax/conf/GENERIC 965 src/sys/arch/vax/conf/GENERIC.MP 966 src/sys/arch/x68k/conf/GENERIC 967 968 src/sys/arch/playstation2/conf/GENERIC 969 970 Branch: yamt-pdpolicy 971 Description: play with page replacement policy 972 - separate page replacement policy from the rest of kernel 973 - implement alternative replacement policy 974 - related read-ahead adjustment?

The audio component has been tested 1133 and verified to work with emuxki and auvia. There may 1134 be a locking issue in the ac97 code at boot. 1135 1136 The are two locks per device instance, an ISR lock and 1137 a character device lock. The ISR lock replaces calls to 1138 splaudio()/splx(), and will be held across calls to device 1139 methods which were called at splaudio() before (e.g. 1140 trigger_output). The character device lock is held across 1141 calls to nearly all of the methods, excluding some only 1142 used for initializtion, e.g. get_locks. This needs to be 1143 documented at merge time. 1144 1145 To test on a multi way x86 system, search for "mpsafe" in 1146 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 1147 that will acquire the ISR lock (depends on the hardware, but 1148 "while true; do mixerctl -a > /dev/null; done" may suffice). 1149 Play audio, run lockstat and verify that that there is 1150 contention on the ISR lock. 1151 1152 ######################################################################## 1153 # Other: 1154 ######################################################################## 1155 1156 Branch: magnum 1157 Description: ? 1158 Status: ? 1159 Start Date: 1160 End Date: 1161 Base Tag: magnum-base 1162 Maintainer: ? 1163 Scope: kernel 1164 Notes: 1165 1166
