1# $NetBSD: BRANCHES,v 1.99 2006/09/18 10:06:58 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 831 file data is the VM cache, which needs to operate 832 in terms of VM pages. As no existing device has native 833 pages the same size as our VM pages, there already is 834 a mapping going on between the VM system and the 835 underlying blocks. So it would be easier and cleaner 836 to adjust that to deal w/ different block sizes. 837 Also with UBC, all i/o is in terms of bytes at an offset 838 with a certain length, so the exact block size isn't a big 839 deal. 840 841 Any other wrstuden-devbsize tag may (and should) go away. 842 843Branch: yamt-km, yamt-km-doc 844Description: simplify/improve kernel memory management and bootstrap 845Status: Terminated; merged to -current 846Start Date: Tue Jan 25 2005 847End Date: Fri Apr 1 2005 848Base Tag: yamt-km-base{,2,3,4}, yamt-km-doc-base 849Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 850Scope: yamt-km: src/sys 851 yamt-km-doc: src/share/man/man9/uvm.9 852Notes: http://mail-index.NetBSD.org/tech-kern/2004/12/25/0005.html 853 854 the followings are per-port status. 855 (account names mean "tested by".) 856 857 works enough to go to multiuser: 858 alpha, i386, xen (yamt@) 859 pc532 (simonb@) 860 alpha, i386, mac68k, macppc, pmax, shark, 861 sparc, sparc64, sun3, x68k (chs@) 862 cobalt, dreamcast, hp300, news68k, newsmips, 863 sun3x (tsutsui@) 864 amiga (mhitch@) 865 cats, hp700 (skrll@) 866 xen (bouyer@) 867 868 known to have the same problem as trunk: 869 vax (chs@, stuck while running kvm_mkdb) 870 871 known to have a problem: 872 luna68k (and, if any, other m68k ports which use TTR) 873 needs to be revisited. 874 -> for luna68k, although not tested, 875 Sysmap has been moved to avoid kva conflict with 876 I/O ranges. 877 878 buildable: 879 src/sys/arch/acorn26/conf/GENERIC 880 src/sys/arch/acorn32/conf/GENERIC 881 src/sys/arch/algor/conf/P6032 882 src/sys/arch/alpha/conf/GENERIC 883 src/sys/arch/alpha/conf/GENERIC.MP 884 src/sys/arch/amd64/conf/GENERIC 885 src/sys/arch/amd64/conf/GENERIC.MP 886 src/sys/arch/amiga/conf/GENERIC 887 src/sys/arch/arc/conf/GENERIC 888 src/sys/arch/atari/conf/MILAN-PCIIDE 889 src/sys/arch/bebox/conf/GENERIC 890 src/sys/arch/cats/conf/GENERIC 891 src/sys/arch/cesfic/conf/GENERIC 892 src/sys/arch/cobalt/conf/GENERIC 893 src/sys/arch/dreamcast/conf/GENERIC 894 src/sys/arch/evbarm/conf/TS7200 895 src/sys/arch/evbppc/conf/WALNUT 896 src/sys/arch/evbsh3/conf/COMPUTEXEVB 897 src/sys/arch/evbsh5/conf/CAYMAN64 898 src/sys/arch/hp300/conf/GENERIC 899 src/sys/arch/hp700/conf/GENERIC 900 src/sys/arch/hpcarm/conf/JORNADA728 901 src/sys/arch/hpcmips/conf/GENERIC 902 src/sys/arch/hpcsh/conf/GENERIC 903 src/sys/arch/hpcsh/conf/HPW650PA 904 src/sys/arch/i386/conf/GENERIC 905 src/sys/arch/i386/conf/GENERIC.MP 906 src/sys/arch/i386/conf/XEN0 907 src/sys/arch/i386/conf/XENU 908 src/sys/arch/ibmnws/conf/GENERIC 909 src/sys/arch/iyonix/conf/GENERIC 910 src/sys/arch/luna68k/conf/GENERIC 911 src/sys/arch/mac68k/conf/GENERIC 912 src/sys/arch/macppc/conf/GENERIC 913 src/sys/arch/macppc/conf/GENERIC.MP 914 src/sys/arch/mipsco/conf/GENERIC 915 src/sys/arch/mmeye/conf/GENERIC 916 src/sys/arch/mvme68k/conf/GENERIC 917 src/sys/arch/netwinder/conf/GENERIC 918 src/sys/arch/news68k/conf/GENERIC 919 src/sys/arch/newsmips/conf/GENERIC 920 src/sys/arch/next68k/conf/GENERIC 921 src/sys/arch/ofppc/conf/GENERIC 922 src/sys/arch/pc532/conf/GENERIC 923 src/sys/arch/pmax/conf/GENERIC 924 src/sys/arch/prep/conf/GENERIC 925 src/sys/arch/sandpoint/conf/GENERIC 926 src/sys/arch/sbmips/conf/GENERIC 927 src/sys/arch/sgimips/conf/GENERIC32_IP3x 928 src/sys/arch/shark/conf/GENERIC 929 src/sys/arch/sparc/conf/GENERIC 930 src/sys/arch/sparc/conf/GENERIC.MP 931 src/sys/arch/sparc64/conf/GENERIC 932 src/sys/arch/sparc64/conf/GENERIC.MP 933 src/sys/arch/sun2/conf/GENERIC 934 src/sys/arch/sun3/conf/GENERIC 935 src/sys/arch/vax/conf/GENERIC 936 src/sys/arch/vax/conf/GENERIC.MP 937 src/sys/arch/x68k/conf/GENERIC 938 939 src/sys/arch/playstation2/conf/GENERIC 940 941Branch: yamt-pdpolicy 942Description: play with page replacement policy 943 - separate page replacement policy from the rest of kernel 944 - implement alternative replacement policy 945 - related read-ahead adjustment?
