1 # $NetBSD: BRANCHES,v 1.130 2006/11/18 06:59:24 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 902 file data is the VM cache, which needs to operate 903 in terms of VM pages. As no existing device has native 904 pages the same size as our VM pages, there already is 905 a mapping going on between the VM system and the 906 underlying blocks. So it would be easier and cleaner 907 to adjust that to deal w/ different block sizes. 908 Also with UBC, all i/o is in terms of bytes at an offset 909 with a certain length, so the exact block size isn't a big 910 deal. 911 912 Any other wrstuden-devbsize tag may (and should) go away. 913 914 Branch: yamt-km, yamt-km-doc 915 Description: simplify/improve kernel memory management and bootstrap 916 Status: Terminated; merged to -current 917 Start Date: Tue Jan 25 2005 918 End Date: Fri Apr 1 2005 919 Base Tag: yamt-km-base{,2,3,4}, yamt-km-doc-base 920 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 921 Scope: yamt-km: src/sys 922 yamt-km-doc: src/share/man/man9/uvm.9 923 Notes: http://mail-index.NetBSD.org/tech-kern/2004/12/25/0005.html 924 925 the followings are per-port status. 926 (account names mean "tested by".) 927 928 works enough to go to multiuser: 929 alpha, i386, xen (yamt@) 930 pc532 (simonb@) 931 alpha, i386, mac68k, macppc, pmax, shark, 932 sparc, sparc64, sun3, x68k (chs@) 933 cobalt, dreamcast, hp300, news68k, newsmips, 934 sun3x (tsutsui@) 935 amiga (mhitch@) 936 cats, hp700 (skrll@) 937 xen (bouyer@) 938 939 known to have the same problem as trunk: 940 vax (chs@, stuck while running kvm_mkdb) 941 942 known to have a problem: 943 luna68k (and, if any, other m68k ports which use TTR) 944 needs to be revisited. 945 -> for luna68k, although not tested, 946 Sysmap has been moved to avoid kva conflict with 947 I/O ranges. 948 949 buildable: 950 src/sys/arch/acorn26/conf/GENERIC 951 src/sys/arch/acorn32/conf/GENERIC 952 src/sys/arch/algor/conf/P6032 953 src/sys/arch/alpha/conf/GENERIC 954 src/sys/arch/alpha/conf/GENERIC.MP 955 src/sys/arch/amd64/conf/GENERIC 956 src/sys/arch/amd64/conf/GENERIC.MP 957 src/sys/arch/amiga/conf/GENERIC 958 src/sys/arch/arc/conf/GENERIC 959 src/sys/arch/atari/conf/MILAN-PCIIDE 960 src/sys/arch/bebox/conf/GENERIC 961 src/sys/arch/cats/conf/GENERIC 962 src/sys/arch/cesfic/conf/GENERIC 963 src/sys/arch/cobalt/conf/GENERIC 964 src/sys/arch/dreamcast/conf/GENERIC 965 src/sys/arch/evbarm/conf/TS7200 966 src/sys/arch/evbppc/conf/WALNUT 967 src/sys/arch/evbsh3/conf/COMPUTEXEVB 968 src/sys/arch/evbsh5/conf/CAYMAN64 969 src/sys/arch/hp300/conf/GENERIC 970 src/sys/arch/hp700/conf/GENERIC 971 src/sys/arch/hpcarm/conf/JORNADA728 972 src/sys/arch/hpcmips/conf/GENERIC 973 src/sys/arch/hpcsh/conf/GENERIC 974 src/sys/arch/hpcsh/conf/HPW650PA 975 src/sys/arch/i386/conf/GENERIC 976 src/sys/arch/i386/conf/GENERIC.MP 977 src/sys/arch/i386/conf/XEN0 978 src/sys/arch/i386/conf/XENU 979 src/sys/arch/ibmnws/conf/GENERIC 980 src/sys/arch/iyonix/conf/GENERIC 981 src/sys/arch/luna68k/conf/GENERIC 982 src/sys/arch/mac68k/conf/GENERIC 983 src/sys/arch/macppc/conf/GENERIC 984 src/sys/arch/macppc/conf/GENERIC.MP 985 src/sys/arch/mipsco/conf/GENERIC 986 src/sys/arch/mmeye/conf/GENERIC 987 src/sys/arch/mvme68k/conf/GENERIC 988 src/sys/arch/netwinder/conf/GENERIC 989 src/sys/arch/news68k/conf/GENERIC 990 src/sys/arch/newsmips/conf/GENERIC 991 src/sys/arch/next68k/conf/GENERIC 992 src/sys/arch/ofppc/conf/GENERIC 993 src/sys/arch/pc532/conf/GENERIC 994 src/sys/arch/pmax/conf/GENERIC 995 src/sys/arch/prep/conf/GENERIC 996 src/sys/arch/sandpoint/conf/GENERIC 997 src/sys/arch/sbmips/conf/GENERIC 998 src/sys/arch/sgimips/conf/GENERIC32_IP3x 999 src/sys/arch/shark/conf/GENERIC 1000 src/sys/arch/sparc/conf/GENERIC 1001 src/sys/arch/sparc/conf/GENERIC.MP 1002 src/sys/arch/sparc64/conf/GENERIC 1003 src/sys/arch/sparc64/conf/GENERIC.MP 1004 src/sys/arch/sun2/conf/GENERIC 1005 src/sys/arch/sun3/conf/GENERIC 1006 src/sys/arch/vax/conf/GENERIC 1007 src/sys/arch/vax/conf/GENERIC.MP 1008 src/sys/arch/x68k/conf/GENERIC 1009 1010 src/sys/arch/playstation2/conf/GENERIC 1011 1012 Branch: yamt-pdpolicy 1013 Description: play with page replacement policy 1014 - separate page replacement policy from the rest of kernel 1015 - implement alternative replacement policy 1016 - related read-ahead adjustment?
