1 # $NetBSD: BRANCHES,v 1.104 2006/09/21 14:33:24 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 847 file data is the VM cache, which needs to operate 848 in terms of VM pages. As no existing device has native 849 pages the same size as our VM pages, there already is 850 a mapping going on between the VM system and the 851 underlying blocks. So it would be easier and cleaner 852 to adjust that to deal w/ different block sizes. 853 Also with UBC, all i/o is in terms of bytes at an offset 854 with a certain length, so the exact block size isn't a big 855 deal. 856 857 Any other wrstuden-devbsize tag may (and should) go away. 858 859 Branch: yamt-km, yamt-km-doc 860 Description: simplify/improve kernel memory management and bootstrap 861 Status: Terminated; merged to -current 862 Start Date: Tue Jan 25 2005 863 End Date: Fri Apr 1 2005 864 Base Tag: yamt-km-base{,2,3,4}, yamt-km-doc-base 865 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 866 Scope: yamt-km: src/sys 867 yamt-km-doc: src/share/man/man9/uvm.9 868 Notes: http://mail-index.NetBSD.org/tech-kern/2004/12/25/0005.html 869 870 the followings are per-port status. 871 (account names mean "tested by".) 872 873 works enough to go to multiuser: 874 alpha, i386, xen (yamt@) 875 pc532 (simonb@) 876 alpha, i386, mac68k, macppc, pmax, shark, 877 sparc, sparc64, sun3, x68k (chs@) 878 cobalt, dreamcast, hp300, news68k, newsmips, 879 sun3x (tsutsui@) 880 amiga (mhitch@) 881 cats, hp700 (skrll@) 882 xen (bouyer@) 883 884 known to have the same problem as trunk: 885 vax (chs@, stuck while running kvm_mkdb) 886 887 known to have a problem: 888 luna68k (and, if any, other m68k ports which use TTR) 889 needs to be revisited. 890 -> for luna68k, although not tested, 891 Sysmap has been moved to avoid kva conflict with 892 I/O ranges. 893 894 buildable: 895 src/sys/arch/acorn26/conf/GENERIC 896 src/sys/arch/acorn32/conf/GENERIC 897 src/sys/arch/algor/conf/P6032 898 src/sys/arch/alpha/conf/GENERIC 899 src/sys/arch/alpha/conf/GENERIC.MP 900 src/sys/arch/amd64/conf/GENERIC 901 src/sys/arch/amd64/conf/GENERIC.MP 902 src/sys/arch/amiga/conf/GENERIC 903 src/sys/arch/arc/conf/GENERIC 904 src/sys/arch/atari/conf/MILAN-PCIIDE 905 src/sys/arch/bebox/conf/GENERIC 906 src/sys/arch/cats/conf/GENERIC 907 src/sys/arch/cesfic/conf/GENERIC 908 src/sys/arch/cobalt/conf/GENERIC 909 src/sys/arch/dreamcast/conf/GENERIC 910 src/sys/arch/evbarm/conf/TS7200 911 src/sys/arch/evbppc/conf/WALNUT 912 src/sys/arch/evbsh3/conf/COMPUTEXEVB 913 src/sys/arch/evbsh5/conf/CAYMAN64 914 src/sys/arch/hp300/conf/GENERIC 915 src/sys/arch/hp700/conf/GENERIC 916 src/sys/arch/hpcarm/conf/JORNADA728 917 src/sys/arch/hpcmips/conf/GENERIC 918 src/sys/arch/hpcsh/conf/GENERIC 919 src/sys/arch/hpcsh/conf/HPW650PA 920 src/sys/arch/i386/conf/GENERIC 921 src/sys/arch/i386/conf/GENERIC.MP 922 src/sys/arch/i386/conf/XEN0 923 src/sys/arch/i386/conf/XENU 924 src/sys/arch/ibmnws/conf/GENERIC 925 src/sys/arch/iyonix/conf/GENERIC 926 src/sys/arch/luna68k/conf/GENERIC 927 src/sys/arch/mac68k/conf/GENERIC 928 src/sys/arch/macppc/conf/GENERIC 929 src/sys/arch/macppc/conf/GENERIC.MP 930 src/sys/arch/mipsco/conf/GENERIC 931 src/sys/arch/mmeye/conf/GENERIC 932 src/sys/arch/mvme68k/conf/GENERIC 933 src/sys/arch/netwinder/conf/GENERIC 934 src/sys/arch/news68k/conf/GENERIC 935 src/sys/arch/newsmips/conf/GENERIC 936 src/sys/arch/next68k/conf/GENERIC 937 src/sys/arch/ofppc/conf/GENERIC 938 src/sys/arch/pc532/conf/GENERIC 939 src/sys/arch/pmax/conf/GENERIC 940 src/sys/arch/prep/conf/GENERIC 941 src/sys/arch/sandpoint/conf/GENERIC 942 src/sys/arch/sbmips/conf/GENERIC 943 src/sys/arch/sgimips/conf/GENERIC32_IP3x 944 src/sys/arch/shark/conf/GENERIC 945 src/sys/arch/sparc/conf/GENERIC 946 src/sys/arch/sparc/conf/GENERIC.MP 947 src/sys/arch/sparc64/conf/GENERIC 948 src/sys/arch/sparc64/conf/GENERIC.MP 949 src/sys/arch/sun2/conf/GENERIC 950 src/sys/arch/sun3/conf/GENERIC 951 src/sys/arch/vax/conf/GENERIC 952 src/sys/arch/vax/conf/GENERIC.MP 953 src/sys/arch/x68k/conf/GENERIC 954 955 src/sys/arch/playstation2/conf/GENERIC 956 957 Branch: yamt-pdpolicy 958 Description: play with page replacement policy 959 - separate page replacement policy from the rest of kernel 960 - implement alternative replacement policy 961 - related read-ahead adjustment?
