1 # $NetBSD: BRANCHES,v 1.153 2007/02/17 10:38:49 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: Dormant 288 Start Date: March 9, 2002 289 End Date: 290 Base Tag: newlock-base 291 Maintainer: Jason R. Thorpe <thorpej (a] NetBSD.org> 292 Scope: Kernel 293 Notes: The goal is to replace the existing lockmgr() and 294 simple_lock() based locking mechanisms with the 295 primitives found in Solaris: mutexes and rwlocks. 296 297 Branch: newlock2 298 Description: New locking primitives, based on Solaris's 299 Status: Active 300 Start Date: September 9, 2006 301 End Date: 302 Base Tag: newlock2-base 303 Maintainer: Andrew Doran <ad (a] NetBSD.org> 304 Scope: Kernel 305 Notes: As per the newlock branch, however given the amount of time 306 the original branch has lain dormant, a new one has been 307 created. Goals: 308 - Implement new locking primitives on most-used ports. 309 - Minor locking improvements. 310 - Remove spinlockmgr(). 311 312 Branch: pkgviews 313 Description: package views, enabling multiple conflicting packages to co-exist 314 Status: Active 315 Start Date: 22 July 2002 316 End Date: 317 Base Tag: pkgviews 318 Maintainer: Alistair Crooks <agc (a] NetBSD.org> 319 Scope: pkgsrc, basesrc/usr.sbin/pkg_install 320 Notes: A more flexible infrastructure for third-party packages by 321 allowing multiple conflicting packages and versions to co-exist 322 within the same tree 323 324 Branch: rpaulo-netinet-merge-pcb 325 Description: merge in6pcb with inpcb 326 Status: Dormant 327 Start Date: Wed Feb 01 2006 328 End Date: 329 Base Tag: rpaulo-netinet-merge-pcb-base 330 Maintainer: Rui Paulo <rpaulo (a] NetBSD.org> 331 Scope: src/sys 332 Notes: No longer active due to the lack of time. If you plan to 333 continue this branch, sys/netinet/in_pcb.h already contains 334 the proposed structure layout (which was roughly discussed 335 in the tech-net mailing list). 336 I also defined INP_*() macros to mimicate FreeBSD's inpcb 337 locking style, but currently they do nothing and are not 338 yet called at the correct places (needs discussion about 339 kernel fine-grained locking). 340 To continue this branch, one needs to read all the relevant 341 inpcb/in6pcb source files and change the function names, 342 structure names, structure fileds according to the new 343 layout (in6pcb is gone). 344 Don't try to build a kernel from this branch because it won't 345 work. The missing pieces required to do a complete build 346 were not committed because they were incomplete and generated 347 panics. 348 You shouldn't need to worry about KAME syncs because 349 they did most of them by now. 350 After the work is done, you are required to test the branch 351 (before the merge to -current) with an interop IPv6 test. 352 More info at: http://www.tahi.org/ 353 354 Branch: rtr-xorg-branch 355 Description: xorg & static build alterations to src/x11 356 Status: Active 357 Start Date: Nov 15 2004 358 End Date: 359 Base tag: rtr-xorg-branch-base 360 Maintainer: Tyler R.

In terms of UBC, the primary cache for 859 file data is the VM cache, which needs to operate 860 in terms of VM pages. As no existing device has native 861 pages the same size as our VM pages, there already is 862 a mapping going on between the VM system and the 863 underlying blocks. So it would be easier and cleaner 864 to adjust that to deal w/ different block sizes. 865 Also with UBC, all i/o is in terms of bytes at an offset 866 with a certain length, so the exact block size isn't a big 867 deal. 868 869 Any other wrstuden-devbsize tag may (and should) go away. 870 871 Branch: yamt-km, yamt-km-doc 872 Description: simplify/improve kernel memory management and bootstrap 873 Status: Terminated; merged to -current 874 Start Date: Tue Jan 25 2005 875 End Date: Fri Apr 1 2005 876 Base Tag: yamt-km-base{,2,3,4}, yamt-km-doc-base 877 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 878 Scope: yamt-km: src/sys 879 yamt-km-doc: src/share/man/man9/uvm.9 880 Notes: http://mail-index.NetBSD.org/tech-kern/2004/12/25/0005.html 881 882 the followings are per-port status. 883 (account names mean "tested by".) 884 885 works enough to go to multiuser: 886 alpha, i386, xen (yamt@) 887 pc532 (simonb@) 888 alpha, i386, mac68k, macppc, pmax, shark, 889 sparc, sparc64, sun3, x68k (chs@) 890 cobalt, dreamcast, hp300, news68k, newsmips, 891 sun3x (tsutsui@) 892 amiga (mhitch@) 893 cats, hp700 (skrll@) 894 xen (bouyer@) 895 896 known to have the same problem as trunk: 897 vax (chs@, stuck while running kvm_mkdb) 898 899 known to have a problem: 900 luna68k (and, if any, other m68k ports which use TTR) 901 needs to be revisited. 902 -> for luna68k, although not tested, 903 Sysmap has been moved to avoid kva conflict with 904 I/O ranges. 905 906 buildable: 907 src/sys/arch/acorn26/conf/GENERIC 908 src/sys/arch/acorn32/conf/GENERIC 909 src/sys/arch/algor/conf/P6032 910 src/sys/arch/alpha/conf/GENERIC 911 src/sys/arch/alpha/conf/GENERIC.MP 912 src/sys/arch/amd64/conf/GENERIC 913 src/sys/arch/amd64/conf/GENERIC.MP 914 src/sys/arch/amiga/conf/GENERIC 915 src/sys/arch/arc/conf/GENERIC 916 src/sys/arch/atari/conf/MILAN-PCIIDE 917 src/sys/arch/bebox/conf/GENERIC 918 src/sys/arch/cats/conf/GENERIC 919 src/sys/arch/cesfic/conf/GENERIC 920 src/sys/arch/cobalt/conf/GENERIC 921 src/sys/arch/dreamcast/conf/GENERIC 922 src/sys/arch/evbarm/conf/TS7200 923 src/sys/arch/evbppc/conf/WALNUT 924 src/sys/arch/evbsh3/conf/COMPUTEXEVB 925 src/sys/arch/evbsh5/conf/CAYMAN64 926 src/sys/arch/hp300/conf/GENERIC 927 src/sys/arch/hp700/conf/GENERIC 928 src/sys/arch/hpcarm/conf/JORNADA728 929 src/sys/arch/hpcmips/conf/GENERIC 930 src/sys/arch/hpcsh/conf/GENERIC 931 src/sys/arch/hpcsh/conf/HPW650PA 932 src/sys/arch/i386/conf/GENERIC 933 src/sys/arch/i386/conf/GENERIC.MP 934 src/sys/arch/i386/conf/XEN0 935 src/sys/arch/i386/conf/XENU 936 src/sys/arch/ibmnws/conf/GENERIC 937 src/sys/arch/iyonix/conf/GENERIC 938 src/sys/arch/luna68k/conf/GENERIC 939 src/sys/arch/mac68k/conf/GENERIC 940 src/sys/arch/macppc/conf/GENERIC 941 src/sys/arch/macppc/conf/GENERIC.MP 942 src/sys/arch/mipsco/conf/GENERIC 943 src/sys/arch/mmeye/conf/GENERIC 944 src/sys/arch/mvme68k/conf/GENERIC 945 src/sys/arch/netwinder/conf/GENERIC 946 src/sys/arch/news68k/conf/GENERIC 947 src/sys/arch/newsmips/conf/GENERIC 948 src/sys/arch/next68k/conf/GENERIC 949 src/sys/arch/ofppc/conf/GENERIC 950 src/sys/arch/pc532/conf/GENERIC 951 src/sys/arch/pmax/conf/GENERIC 952 src/sys/arch/prep/conf/GENERIC 953 src/sys/arch/sandpoint/conf/GENERIC 954 src/sys/arch/sbmips/conf/GENERIC 955 src/sys/arch/sgimips/conf/GENERIC32_IP3x 956 src/sys/arch/shark/conf/GENERIC 957 src/sys/arch/sparc/conf/GENERIC 958 src/sys/arch/sparc/conf/GENERIC.MP 959 src/sys/arch/sparc64/conf/GENERIC 960 src/sys/arch/sparc64/conf/GENERIC.MP 961 src/sys/arch/sun2/conf/GENERIC 962 src/sys/arch/sun3/conf/GENERIC 963 src/sys/arch/vax/conf/GENERIC 964 src/sys/arch/vax/conf/GENERIC.MP 965 src/sys/arch/x68k/conf/GENERIC 966 967 src/sys/arch/playstation2/conf/GENERIC 968 969 Branch: yamt-pdpolicy 970 Description: play with page replacement policy 971 - separate page replacement policy from the rest of kernel 972 - implement alternative replacement policy 973 - related read-ahead adjustment?
