1 # $NetBSD: BRANCHES,v 1.117 2006/10/09 11:30:53 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.

In terms of UBC, the primary cache for 851 file data is the VM cache, which needs to operate 852 in terms of VM pages. As no existing device has native 853 pages the same size as our VM pages, there already is 854 a mapping going on between the VM system and the 855 underlying blocks. So it would be easier and cleaner 856 to adjust that to deal w/ different block sizes. 857 Also with UBC, all i/o is in terms of bytes at an offset 858 with a certain length, so the exact block size isn't a big 859 deal. 860 861 Any other wrstuden-devbsize tag may (and should) go away. 862 863 Branch: yamt-km, yamt-km-doc 864 Description: simplify/improve kernel memory management and bootstrap 865 Status: Terminated; merged to -current 866 Start Date: Tue Jan 25 2005 867 End Date: Fri Apr 1 2005 868 Base Tag: yamt-km-base{,2,3,4}, yamt-km-doc-base 869 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 870 Scope: yamt-km: src/sys 871 yamt-km-doc: src/share/man/man9/uvm.9 872 Notes: http://mail-index.NetBSD.org/tech-kern/2004/12/25/0005.html 873 874 the followings are per-port status. 875 (account names mean "tested by".) 876 877 works enough to go to multiuser: 878 alpha, i386, xen (yamt@) 879 pc532 (simonb@) 880 alpha, i386, mac68k, macppc, pmax, shark, 881 sparc, sparc64, sun3, x68k (chs@) 882 cobalt, dreamcast, hp300, news68k, newsmips, 883 sun3x (tsutsui@) 884 amiga (mhitch@) 885 cats, hp700 (skrll@) 886 xen (bouyer@) 887 888 known to have the same problem as trunk: 889 vax (chs@, stuck while running kvm_mkdb) 890 891 known to have a problem: 892 luna68k (and, if any, other m68k ports which use TTR) 893 needs to be revisited. 894 -> for luna68k, although not tested, 895 Sysmap has been moved to avoid kva conflict with 896 I/O ranges. 897 898 buildable: 899 src/sys/arch/acorn26/conf/GENERIC 900 src/sys/arch/acorn32/conf/GENERIC 901 src/sys/arch/algor/conf/P6032 902 src/sys/arch/alpha/conf/GENERIC 903 src/sys/arch/alpha/conf/GENERIC.MP 904 src/sys/arch/amd64/conf/GENERIC 905 src/sys/arch/amd64/conf/GENERIC.MP 906 src/sys/arch/amiga/conf/GENERIC 907 src/sys/arch/arc/conf/GENERIC 908 src/sys/arch/atari/conf/MILAN-PCIIDE 909 src/sys/arch/bebox/conf/GENERIC 910 src/sys/arch/cats/conf/GENERIC 911 src/sys/arch/cesfic/conf/GENERIC 912 src/sys/arch/cobalt/conf/GENERIC 913 src/sys/arch/dreamcast/conf/GENERIC 914 src/sys/arch/evbarm/conf/TS7200 915 src/sys/arch/evbppc/conf/WALNUT 916 src/sys/arch/evbsh3/conf/COMPUTEXEVB 917 src/sys/arch/evbsh5/conf/CAYMAN64 918 src/sys/arch/hp300/conf/GENERIC 919 src/sys/arch/hp700/conf/GENERIC 920 src/sys/arch/hpcarm/conf/JORNADA728 921 src/sys/arch/hpcmips/conf/GENERIC 922 src/sys/arch/hpcsh/conf/GENERIC 923 src/sys/arch/hpcsh/conf/HPW650PA 924 src/sys/arch/i386/conf/GENERIC 925 src/sys/arch/i386/conf/GENERIC.MP 926 src/sys/arch/i386/conf/XEN0 927 src/sys/arch/i386/conf/XENU 928 src/sys/arch/ibmnws/conf/GENERIC 929 src/sys/arch/iyonix/conf/GENERIC 930 src/sys/arch/luna68k/conf/GENERIC 931 src/sys/arch/mac68k/conf/GENERIC 932 src/sys/arch/macppc/conf/GENERIC 933 src/sys/arch/macppc/conf/GENERIC.MP 934 src/sys/arch/mipsco/conf/GENERIC 935 src/sys/arch/mmeye/conf/GENERIC 936 src/sys/arch/mvme68k/conf/GENERIC 937 src/sys/arch/netwinder/conf/GENERIC 938 src/sys/arch/news68k/conf/GENERIC 939 src/sys/arch/newsmips/conf/GENERIC 940 src/sys/arch/next68k/conf/GENERIC 941 src/sys/arch/ofppc/conf/GENERIC 942 src/sys/arch/pc532/conf/GENERIC 943 src/sys/arch/pmax/conf/GENERIC 944 src/sys/arch/prep/conf/GENERIC 945 src/sys/arch/sandpoint/conf/GENERIC 946 src/sys/arch/sbmips/conf/GENERIC 947 src/sys/arch/sgimips/conf/GENERIC32_IP3x 948 src/sys/arch/shark/conf/GENERIC 949 src/sys/arch/sparc/conf/GENERIC 950 src/sys/arch/sparc/conf/GENERIC.MP 951 src/sys/arch/sparc64/conf/GENERIC 952 src/sys/arch/sparc64/conf/GENERIC.MP 953 src/sys/arch/sun2/conf/GENERIC 954 src/sys/arch/sun3/conf/GENERIC 955 src/sys/arch/vax/conf/GENERIC 956 src/sys/arch/vax/conf/GENERIC.MP 957 src/sys/arch/x68k/conf/GENERIC 958 959 src/sys/arch/playstation2/conf/GENERIC 960 961 Branch: yamt-pdpolicy 962 Description: play with page replacement policy 963 - separate page replacement policy from the rest of kernel 964 - implement alternative replacement policy 965 - related read-ahead adjustment?
