1# $NetBSD: BRANCHES,v 1.109 2006/09/30 12:58:31 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.

In terms of UBC, the primary cache for 870 file data is the VM cache, which needs to operate 871 in terms of VM pages. As no existing device has native 872 pages the same size as our VM pages, there already is 873 a mapping going on between the VM system and the 874 underlying blocks. So it would be easier and cleaner 875 to adjust that to deal w/ different block sizes. 876 Also with UBC, all i/o is in terms of bytes at an offset 877 with a certain length, so the exact block size isn't a big 878 deal. 879 880 Any other wrstuden-devbsize tag may (and should) go away. 881 882Branch: yamt-km, yamt-km-doc 883Description: simplify/improve kernel memory management and bootstrap 884Status: Terminated; merged to -current 885Start Date: Tue Jan 25 2005 886End Date: Fri Apr 1 2005 887Base Tag: yamt-km-base{,2,3,4}, yamt-km-doc-base 888Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 889Scope: yamt-km: src/sys 890 yamt-km-doc: src/share/man/man9/uvm.9 891Notes: http://mail-index.NetBSD.org/tech-kern/2004/12/25/0005.html 892 893 the followings are per-port status. 894 (account names mean "tested by".) 895 896 works enough to go to multiuser: 897 alpha, i386, xen (yamt@) 898 pc532 (simonb@) 899 alpha, i386, mac68k, macppc, pmax, shark, 900 sparc, sparc64, sun3, x68k (chs@) 901 cobalt, dreamcast, hp300, news68k, newsmips, 902 sun3x (tsutsui@) 903 amiga (mhitch@) 904 cats, hp700 (skrll@) 905 xen (bouyer@) 906 907 known to have the same problem as trunk: 908 vax (chs@, stuck while running kvm_mkdb) 909 910 known to have a problem: 911 luna68k (and, if any, other m68k ports which use TTR) 912 needs to be revisited. 913 -> for luna68k, although not tested, 914 Sysmap has been moved to avoid kva conflict with 915 I/O ranges. 916 917 buildable: 918 src/sys/arch/acorn26/conf/GENERIC 919 src/sys/arch/acorn32/conf/GENERIC 920 src/sys/arch/algor/conf/P6032 921 src/sys/arch/alpha/conf/GENERIC 922 src/sys/arch/alpha/conf/GENERIC.MP 923 src/sys/arch/amd64/conf/GENERIC 924 src/sys/arch/amd64/conf/GENERIC.MP 925 src/sys/arch/amiga/conf/GENERIC 926 src/sys/arch/arc/conf/GENERIC 927 src/sys/arch/atari/conf/MILAN-PCIIDE 928 src/sys/arch/bebox/conf/GENERIC 929 src/sys/arch/cats/conf/GENERIC 930 src/sys/arch/cesfic/conf/GENERIC 931 src/sys/arch/cobalt/conf/GENERIC 932 src/sys/arch/dreamcast/conf/GENERIC 933 src/sys/arch/evbarm/conf/TS7200 934 src/sys/arch/evbppc/conf/WALNUT 935 src/sys/arch/evbsh3/conf/COMPUTEXEVB 936 src/sys/arch/evbsh5/conf/CAYMAN64 937 src/sys/arch/hp300/conf/GENERIC 938 src/sys/arch/hp700/conf/GENERIC 939 src/sys/arch/hpcarm/conf/JORNADA728 940 src/sys/arch/hpcmips/conf/GENERIC 941 src/sys/arch/hpcsh/conf/GENERIC 942 src/sys/arch/hpcsh/conf/HPW650PA 943 src/sys/arch/i386/conf/GENERIC 944 src/sys/arch/i386/conf/GENERIC.MP 945 src/sys/arch/i386/conf/XEN0 946 src/sys/arch/i386/conf/XENU 947 src/sys/arch/ibmnws/conf/GENERIC 948 src/sys/arch/iyonix/conf/GENERIC 949 src/sys/arch/luna68k/conf/GENERIC 950 src/sys/arch/mac68k/conf/GENERIC 951 src/sys/arch/macppc/conf/GENERIC 952 src/sys/arch/macppc/conf/GENERIC.MP 953 src/sys/arch/mipsco/conf/GENERIC 954 src/sys/arch/mmeye/conf/GENERIC 955 src/sys/arch/mvme68k/conf/GENERIC 956 src/sys/arch/netwinder/conf/GENERIC 957 src/sys/arch/news68k/conf/GENERIC 958 src/sys/arch/newsmips/conf/GENERIC 959 src/sys/arch/next68k/conf/GENERIC 960 src/sys/arch/ofppc/conf/GENERIC 961 src/sys/arch/pc532/conf/GENERIC 962 src/sys/arch/pmax/conf/GENERIC 963 src/sys/arch/prep/conf/GENERIC 964 src/sys/arch/sandpoint/conf/GENERIC 965 src/sys/arch/sbmips/conf/GENERIC 966 src/sys/arch/sgimips/conf/GENERIC32_IP3x 967 src/sys/arch/shark/conf/GENERIC 968 src/sys/arch/sparc/conf/GENERIC 969 src/sys/arch/sparc/conf/GENERIC.MP 970 src/sys/arch/sparc64/conf/GENERIC 971 src/sys/arch/sparc64/conf/GENERIC.MP 972 src/sys/arch/sun2/conf/GENERIC 973 src/sys/arch/sun3/conf/GENERIC 974 src/sys/arch/vax/conf/GENERIC 975 src/sys/arch/vax/conf/GENERIC.MP 976 src/sys/arch/x68k/conf/GENERIC 977 978 src/sys/arch/playstation2/conf/GENERIC 979 980Branch: yamt-pdpolicy 981Description: play with page replacement policy 982 - separate page replacement policy from the rest of kernel 983 - implement alternative replacement policy 984 - related read-ahead adjustment?
