1# $NetBSD: BRANCHES,v 1.138 2006/12/02 22:31:05 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 47Branch: comdex-fall-1999 48Description: Special release branch for pre-1.5 release at 49 Fall 1999 COMDEX. 50Status: Terminated 51Start Date: 52End Date: 53Base Tag: comdex-fall-1999-base 54Maintainer: ? 55Scope: Entire tree. 56Notes: 57 58Branch: netbsd-0-9 59Description: The NetBSD 0.9 release branch 60Status: Terminated 61Start Date: 62End Date: 63Base Tag: netbsd-0-9-base 64Maintainer: Release Engineering <releng@NetBSD.org> 65Scope: Entire tree. 66Notes: 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 70Branch: netbsd-1-0 71Description: The NetBSD 1.0 release branch 72Status: Terminated 73Start Date: 74End Date: 75Base Tag: netbsd-1-0-base 76Maintainer: Release Engineering <releng@NetBSD.org> 77Scope: Entire tree. 78Notes: 79 Commits restricted to release engineering. 80 81Branch: netbsd-1-1 82Description: The NetBSD 1.1 release branch 83Status: Terminated 84Start Date: 85End Date: 86Base Tag: netbsd-1-1-base 87Maintainer: Release Engineering <releng@NetBSD.org> 88Scope: Entire tree. 89Notes: 90 Commits restricted to release engineering. 91 92Branch: netbsd-1-2 93Description: The NetBSD 1.2 release branch 94Status: Terminated 95Start Date: 96End Date: 97Base Tag: netbsd-1-2-base 98Maintainer: Release Engineering <releng@NetBSD.org> 99Scope: Entire tree. 100Notes: 101 Commits restricted to release engineering. 102 103Branch: netbsd-1-3 104Description: The NetBSD 1.3 release branch 105Status: Terminated 106Start Date: 107End Date: 108Base Tag: netbsd-1-3-base 109Maintainer: Release Engineering <releng@NetBSD.org> 110Scope: Entire tree. 111Notes: 112 Commits restricted to release engineering. 113 114Branch: netbsd-1-4 115Description: The NetBSD 1.4 release branch 116Status: Terminated 117Start Date: 1 Apr 2000 118End Date: 119Base Tag: netbsd-1-4-base 120Maintainer: 1.4 Release Engineering <releng-1-4@NetBSD.org> 121Scope: Entire tree. 122Notes: 123 Commits restricted to release engineering. 124 125Branch: netbsd-1-5 126Description: The NetBSD 1.5 release branch 127Status: Terminated 128Start Date: 20 Jun 2000 129End Date: 26 Jan 2005 130Base Tag: netbsd-1-5-base 131Maintainer: 1.5 Release Engineering <releng-1-5@NetBSD.org> 132Scope: Entire tree. 133Notes: 134 Commits restricted to release engineering. 135 136Branch: netbsd-1-6 137Description: The NetBSD 1.6 release branch 138Status: Terminated 139Start Date: 22 May 2002 140End Date: 141Base Tag: netbsd-1-6-base 142Maintainer: 1.6 Release Engineering <releng-1-6@NetBSD.org> 143Scope: Entire tree. 144Notes: 145 Commits restricted to Release Engineering. 146 147Branch: netbsd-2 148Description: The NetBSD 2 release branch 149Status: Active 150Start Date: 23 Dec 2004 151End Date: 152Base Tag: netbsd-2-base 153Maintainer: 2 Release Engineering <releng-2@NetBSD.org> 154Scope: 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 238Branch: gmcgarry_ucred 239Description: Integrate and encapsulate user credentials 240Status: Dormant 241Start Date: 18 December 2002 242End Date: 243Base Tag: gmcgarry_ucred_base 244Maintainer: Gregory McGarry <gmcgarry@NetBSD.org> 245Scope: kernel 246Notes: merge pcred and ucred and poolify 247 248Branch: kame 249Description: KAME Project 250Status: Dormant 251Start Date: 28 Jun 1999 252End Date: 253Base Tag: 254Maintainer: Jun-ichiro itojun Hagino <itojun@NetBSD.org> 255Scope: kernel 256Notes: http://www.kame.net 257 Used for "reference" purposes for early part of KAME 258 integration effort.

Goals: 308 - Implement new locking primitives on most-used ports. 309 - Minor locking improvements. 310 - Remove spinlockmgr(). 311 312Branch: pkgviews 313Description: package views, enabling multiple conflicting packages to co-exist 314Status: Active 315Start Date: 22 July 2002 316End Date: 317Base Tag: pkgviews 318Maintainer: Alistair Crooks <agc@NetBSD.org> 319Scope: pkgsrc, basesrc/usr.sbin/pkg_install 320Notes: 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 324Branch: rpaulo-netinet-merge-pcb 325Description: merge in6pcb with inpcb 326Status: Dormant 327Start Date: Wed Feb 01 2006 328End Date: 329Base Tag: rpaulo-netinet-merge-pcb-base 330Maintainer: Rui Paulo <rpaulo@NetBSD.org> 331Scope: src/sys 332Notes: 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 354Branch: rtr-xorg-branch 355Description: xorg & static build alterations to src/x11 356Status: Active 357Start Date: Nov 15 2004 358End Date: 359Base tag: rtr-xorg-branch-base 360Maintainer: Tyler R.

In terms of UBC, the primary cache for 930 file data is the VM cache, which needs to operate 931 in terms of VM pages. As no existing device has native 932 pages the same size as our VM pages, there already is 933 a mapping going on between the VM system and the 934 underlying blocks. So it would be easier and cleaner 935 to adjust that to deal w/ different block sizes. 936 Also with UBC, all i/o is in terms of bytes at an offset 937 with a certain length, so the exact block size isn't a big 938 deal. 939 940 Any other wrstuden-devbsize tag may (and should) go away. 941 942Branch: yamt-km, yamt-km-doc 943Description: simplify/improve kernel memory management and bootstrap 944Status: Terminated; merged to -current 945Start Date: Tue Jan 25 2005 946End Date: Fri Apr 1 2005 947Base Tag: yamt-km-base{,2,3,4}, yamt-km-doc-base 948Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 949Scope: yamt-km: src/sys 950 yamt-km-doc: src/share/man/man9/uvm.9 951Notes: http://mail-index.NetBSD.org/tech-kern/2004/12/25/0005.html 952 953 the followings are per-port status. 954 (account names mean "tested by".) 955 956 works enough to go to multiuser: 957 alpha, i386, xen (yamt@) 958 pc532 (simonb@) 959 alpha, i386, mac68k, macppc, pmax, shark, 960 sparc, sparc64, sun3, x68k (chs@) 961 cobalt, dreamcast, hp300, news68k, newsmips, 962 sun3x (tsutsui@) 963 amiga (mhitch@) 964 cats, hp700 (skrll@) 965 xen (bouyer@) 966 967 known to have the same problem as trunk: 968 vax (chs@, stuck while running kvm_mkdb) 969 970 known to have a problem: 971 luna68k (and, if any, other m68k ports which use TTR) 972 needs to be revisited. 973 -> for luna68k, although not tested, 974 Sysmap has been moved to avoid kva conflict with 975 I/O ranges. 976 977 buildable: 978 src/sys/arch/acorn26/conf/GENERIC 979 src/sys/arch/acorn32/conf/GENERIC 980 src/sys/arch/algor/conf/P6032 981 src/sys/arch/alpha/conf/GENERIC 982 src/sys/arch/alpha/conf/GENERIC.MP 983 src/sys/arch/amd64/conf/GENERIC 984 src/sys/arch/amd64/conf/GENERIC.MP 985 src/sys/arch/amiga/conf/GENERIC 986 src/sys/arch/arc/conf/GENERIC 987 src/sys/arch/atari/conf/MILAN-PCIIDE 988 src/sys/arch/bebox/conf/GENERIC 989 src/sys/arch/cats/conf/GENERIC 990 src/sys/arch/cesfic/conf/GENERIC 991 src/sys/arch/cobalt/conf/GENERIC 992 src/sys/arch/dreamcast/conf/GENERIC 993 src/sys/arch/evbarm/conf/TS7200 994 src/sys/arch/evbppc/conf/WALNUT 995 src/sys/arch/evbsh3/conf/COMPUTEXEVB 996 src/sys/arch/evbsh5/conf/CAYMAN64 997 src/sys/arch/hp300/conf/GENERIC 998 src/sys/arch/hp700/conf/GENERIC 999 src/sys/arch/hpcarm/conf/JORNADA728 1000 src/sys/arch/hpcmips/conf/GENERIC 1001 src/sys/arch/hpcsh/conf/GENERIC 1002 src/sys/arch/hpcsh/conf/HPW650PA 1003 src/sys/arch/i386/conf/GENERIC 1004 src/sys/arch/i386/conf/GENERIC.MP 1005 src/sys/arch/i386/conf/XEN0 1006 src/sys/arch/i386/conf/XENU 1007 src/sys/arch/ibmnws/conf/GENERIC 1008 src/sys/arch/iyonix/conf/GENERIC 1009 src/sys/arch/luna68k/conf/GENERIC 1010 src/sys/arch/mac68k/conf/GENERIC 1011 src/sys/arch/macppc/conf/GENERIC 1012 src/sys/arch/macppc/conf/GENERIC.MP 1013 src/sys/arch/mipsco/conf/GENERIC 1014 src/sys/arch/mmeye/conf/GENERIC 1015 src/sys/arch/mvme68k/conf/GENERIC 1016 src/sys/arch/netwinder/conf/GENERIC 1017 src/sys/arch/news68k/conf/GENERIC 1018 src/sys/arch/newsmips/conf/GENERIC 1019 src/sys/arch/next68k/conf/GENERIC 1020 src/sys/arch/ofppc/conf/GENERIC 1021 src/sys/arch/pc532/conf/GENERIC 1022 src/sys/arch/pmax/conf/GENERIC 1023 src/sys/arch/prep/conf/GENERIC 1024 src/sys/arch/sandpoint/conf/GENERIC 1025 src/sys/arch/sbmips/conf/GENERIC 1026 src/sys/arch/sgimips/conf/GENERIC32_IP3x 1027 src/sys/arch/shark/conf/GENERIC 1028 src/sys/arch/sparc/conf/GENERIC 1029 src/sys/arch/sparc/conf/GENERIC.MP 1030 src/sys/arch/sparc64/conf/GENERIC 1031 src/sys/arch/sparc64/conf/GENERIC.MP 1032 src/sys/arch/sun2/conf/GENERIC 1033 src/sys/arch/sun3/conf/GENERIC 1034 src/sys/arch/vax/conf/GENERIC 1035 src/sys/arch/vax/conf/GENERIC.MP 1036 src/sys/arch/x68k/conf/GENERIC 1037 1038 src/sys/arch/playstation2/conf/GENERIC 1039 1040Branch: yamt-pdpolicy 1041Description: play with page replacement policy 1042 - separate page replacement policy from the rest of kernel 1043 - implement alternative replacement policy 1044 - related read-ahead adjustment?
