1# $NetBSD: BRANCHES,v 1.86 2006/06/21 15:20:39 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: Active 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-2-0 148Description: Originally the NetBSD 2.0 release branch and now the branch 149 tracking security/critical fixes for the NetBSD 2.0 series 150Status: Active 151Start Date: 28 Mar 2004 and changed for security/critical function on 152 23 Dec 2004 153End Date: 154Base Tag: netbsd-2-0-base 155Maintainer: 2.0 Release Engineering <releng-2-0@NetBSD.org> 156Scope: Entire tree.

Also DEV_BSIZE would go away. 806Status: Terminated 807Start Date: Aug or Sept 1999 808End Date: 1 Apr 2000 809Base tag: wrstuden-devbsize-base 810Maintainer: Bill Studenmund <wrstuden@NetBSD.org> 811Scope: kernel 812Notes: No longer active due to lack of time, and introduction 813 of UBC. In terms of UBC, the primary cache for 814 file data is the VM cache, which needs to operate 815 in terms of VM pages. As no existing device has native 816 pages the same size as our VM pages, there already is 817 a mapping going on between the VM system and the 818 underlying blocks. So it would be easier and cleaner 819 to adjust that to deal w/ different block sizes. 820 Also with UBC, all i/o is in terms of bytes at an offset 821 with a certain length, so the exact block size isn't a big 822 deal. 823 824 Any other wrstuden-devbsize tag may (and should) go away. 825 826Branch: yamt-km, yamt-km-doc 827Description: simplify/improve kernel memory management and bootstrap 828Status: Terminated; merged to -current 829Start Date: Tue Jan 25 2005 830End Date: Fri Apr 1 2005 831Base Tag: yamt-km-base{,2,3,4}, yamt-km-doc-base 832Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 833Scope: yamt-km: src/sys 834 yamt-km-doc: src/share/man/man9/uvm.9 835Notes: http://mail-index.NetBSD.org/tech-kern/2004/12/25/0005.html 836 837 the followings are per-port status. 838 (account names mean "tested by".) 839 840 works enough to go to multiuser: 841 alpha, i386, xen (yamt@) 842 pc532 (simonb@) 843 alpha, i386, mac68k, macppc, pmax, shark, 844 sparc, sparc64, sun3, x68k (chs@) 845 cobalt, dreamcast, hp300, news68k, newsmips, 846 sun3x (tsutsui@) 847 amiga (mhitch@) 848 cats, hp700 (skrll@) 849 xen (bouyer@) 850 851 known to have the same problem as trunk: 852 vax (chs@, stuck while running kvm_mkdb) 853 854 known to have a problem: 855 luna68k (and, if any, other m68k ports which use TTR) 856 needs to be revisited. 857 -> for luna68k, although not tested, 858 Sysmap has been moved to avoid kva conflict with 859 I/O ranges. 860 861 buildable: 862 src/sys/arch/acorn26/conf/GENERIC 863 src/sys/arch/acorn32/conf/GENERIC 864 src/sys/arch/algor/conf/P6032 865 src/sys/arch/alpha/conf/GENERIC 866 src/sys/arch/alpha/conf/GENERIC.MP 867 src/sys/arch/amd64/conf/GENERIC 868 src/sys/arch/amd64/conf/GENERIC.MP 869 src/sys/arch/amiga/conf/GENERIC 870 src/sys/arch/arc/conf/GENERIC 871 src/sys/arch/atari/conf/MILAN-PCIIDE 872 src/sys/arch/bebox/conf/GENERIC 873 src/sys/arch/cats/conf/GENERIC 874 src/sys/arch/cesfic/conf/GENERIC 875 src/sys/arch/cobalt/conf/GENERIC 876 src/sys/arch/dreamcast/conf/GENERIC 877 src/sys/arch/evbarm/conf/TS7200 878 src/sys/arch/evbppc/conf/WALNUT 879 src/sys/arch/evbsh3/conf/COMPUTEXEVB 880 src/sys/arch/evbsh5/conf/CAYMAN64 881 src/sys/arch/hp300/conf/GENERIC 882 src/sys/arch/hp700/conf/GENERIC 883 src/sys/arch/hpcarm/conf/JORNADA728 884 src/sys/arch/hpcmips/conf/GENERIC 885 src/sys/arch/hpcsh/conf/GENERIC 886 src/sys/arch/hpcsh/conf/HPW650PA 887 src/sys/arch/i386/conf/GENERIC 888 src/sys/arch/i386/conf/GENERIC.MP 889 src/sys/arch/i386/conf/XEN0 890 src/sys/arch/i386/conf/XENU 891 src/sys/arch/ibmnws/conf/GENERIC 892 src/sys/arch/iyonix/conf/GENERIC 893 src/sys/arch/luna68k/conf/GENERIC 894 src/sys/arch/mac68k/conf/GENERIC 895 src/sys/arch/macppc/conf/GENERIC 896 src/sys/arch/macppc/conf/GENERIC.MP 897 src/sys/arch/mipsco/conf/GENERIC 898 src/sys/arch/mmeye/conf/GENERIC 899 src/sys/arch/mvme68k/conf/GENERIC 900 src/sys/arch/netwinder/conf/GENERIC 901 src/sys/arch/news68k/conf/GENERIC 902 src/sys/arch/newsmips/conf/GENERIC 903 src/sys/arch/next68k/conf/GENERIC 904 src/sys/arch/ofppc/conf/GENERIC 905 src/sys/arch/pc532/conf/GENERIC 906 src/sys/arch/pmax/conf/GENERIC 907 src/sys/arch/prep/conf/GENERIC 908 src/sys/arch/sandpoint/conf/GENERIC 909 src/sys/arch/sbmips/conf/GENERIC 910 src/sys/arch/sgimips/conf/GENERIC32_IP3x 911 src/sys/arch/shark/conf/GENERIC 912 src/sys/arch/sparc/conf/GENERIC 913 src/sys/arch/sparc/conf/GENERIC.MP 914 src/sys/arch/sparc64/conf/GENERIC 915 src/sys/arch/sparc64/conf/GENERIC.MP 916 src/sys/arch/sun2/conf/GENERIC 917 src/sys/arch/sun3/conf/GENERIC 918 src/sys/arch/vax/conf/GENERIC 919 src/sys/arch/vax/conf/GENERIC.MP 920 src/sys/arch/x68k/conf/GENERIC 921 922 src/sys/arch/playstation2/conf/GENERIC 923 924Branch: yamt-readahead 925Description: play with file readahead 926Status: Terminated; merged to -current 927Start Date: Mon Nov 14 2005 928End Date: Wed Nov 30 2005 929Base Tag: yamt-readahead-base3 930Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 931Scope: src/sys 932Notes: 933 934Branch: yamt-uio_vmspace 935Description: uio_lwp/uio_segflg -> uio_vmspace 936Status: Terminated; merged to -current 937Start Date: Mon Dec 31 2005 938End Date: Wed Mar 1 2006 939Base Tag: yamt-uio_vmspace-base5 940Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 941Scope: src/sys 942Notes: 943 944Branch: yamt-vop 945Description: remove several VOPs 946Status: Terminated; merged to -current 947Start Date: Wed Oct 19 2005 948End Date: Wed Nov 2 2005 949Base Tag: yamt-vop-base3 950Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 951Scope: src/sys 952Notes: http://mail-index.NetBSD.org/tech-kern/2005/09/27/0000.html 953 954 955######################################################################## 956# Other: 957######################################################################## 958 959Branch: magnum 960Description: ? 961Status: ? 962Start Date: 963End Date: 964Base Tag: magnum-base 965Maintainer: ? 966Scope: kernel 967Notes: 968 969
