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 844 file data is the VM cache, which needs to operate 845 in terms of VM pages. As no existing device has native 846 pages the same size as our VM pages, there already is 847 a mapping going on between the VM system and the 848 underlying blocks. So it would be easier and cleaner 849 to adjust that to deal w/ different block sizes. 850 Also with UBC, all i/o is in terms of bytes at an offset 851 with a certain length, so the exact block size isn't a big 852 deal. 853 854 Any other wrstuden-devbsize tag may (and should) go away. 855 856 Branch: yamt-km, yamt-km-doc 857 Description: simplify/improve kernel memory management and bootstrap 858 Status: Terminated; merged to -current 859 Start Date: Tue Jan 25 2005 860 End Date: Fri Apr 1 2005 861 Base Tag: yamt-km-base{,2,3,4}, yamt-km-doc-base 862 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 863 Scope: yamt-km: src/sys 864 yamt-km-doc: src/share/man/man9/uvm.9 865 Notes: http://mail-index.NetBSD.org/tech-kern/2004/12/25/0005.html 866 867 the followings are per-port status. 868 (account names mean "tested by".) 869 870 works enough to go to multiuser: 871 alpha, i386, xen (yamt@) 872 pc532 (simonb@) 873 alpha, i386, mac68k, macppc, pmax, shark, 874 sparc, sparc64, sun3, x68k (chs@) 875 cobalt, dreamcast, hp300, news68k, newsmips, 876 sun3x (tsutsui@) 877 amiga (mhitch@) 878 cats, hp700 (skrll@) 879 xen (bouyer@) 880 881 known to have the same problem as trunk: 882 vax (chs@, stuck while running kvm_mkdb) 883 884 known to have a problem: 885 luna68k (and, if any, other m68k ports which use TTR) 886 needs to be revisited. 887 -> for luna68k, although not tested, 888 Sysmap has been moved to avoid kva conflict with 889 I/O ranges. 890 891 buildable: 892 src/sys/arch/acorn26/conf/GENERIC 893 src/sys/arch/acorn32/conf/GENERIC 894 src/sys/arch/algor/conf/P6032 895 src/sys/arch/alpha/conf/GENERIC 896 src/sys/arch/alpha/conf/GENERIC.MP 897 src/sys/arch/amd64/conf/GENERIC 898 src/sys/arch/amd64/conf/GENERIC.MP 899 src/sys/arch/amiga/conf/GENERIC 900 src/sys/arch/arc/conf/GENERIC 901 src/sys/arch/atari/conf/MILAN-PCIIDE 902 src/sys/arch/bebox/conf/GENERIC 903 src/sys/arch/cats/conf/GENERIC 904 src/sys/arch/cesfic/conf/GENERIC 905 src/sys/arch/cobalt/conf/GENERIC 906 src/sys/arch/dreamcast/conf/GENERIC 907 src/sys/arch/evbarm/conf/TS7200 908 src/sys/arch/evbppc/conf/WALNUT 909 src/sys/arch/evbsh3/conf/COMPUTEXEVB 910 src/sys/arch/evbsh5/conf/CAYMAN64 911 src/sys/arch/hp300/conf/GENERIC 912 src/sys/arch/hp700/conf/GENERIC 913 src/sys/arch/hpcarm/conf/JORNADA728 914 src/sys/arch/hpcmips/conf/GENERIC 915 src/sys/arch/hpcsh/conf/GENERIC 916 src/sys/arch/hpcsh/conf/HPW650PA 917 src/sys/arch/i386/conf/GENERIC 918 src/sys/arch/i386/conf/GENERIC.MP 919 src/sys/arch/i386/conf/XEN0 920 src/sys/arch/i386/conf/XENU 921 src/sys/arch/ibmnws/conf/GENERIC 922 src/sys/arch/iyonix/conf/GENERIC 923 src/sys/arch/luna68k/conf/GENERIC 924 src/sys/arch/mac68k/conf/GENERIC 925 src/sys/arch/macppc/conf/GENERIC 926 src/sys/arch/macppc/conf/GENERIC.MP 927 src/sys/arch/mipsco/conf/GENERIC 928 src/sys/arch/mmeye/conf/GENERIC 929 src/sys/arch/mvme68k/conf/GENERIC 930 src/sys/arch/netwinder/conf/GENERIC 931 src/sys/arch/news68k/conf/GENERIC 932 src/sys/arch/newsmips/conf/GENERIC 933 src/sys/arch/next68k/conf/GENERIC 934 src/sys/arch/ofppc/conf/GENERIC 935 src/sys/arch/pc532/conf/GENERIC 936 src/sys/arch/pmax/conf/GENERIC 937 src/sys/arch/prep/conf/GENERIC 938 src/sys/arch/sandpoint/conf/GENERIC 939 src/sys/arch/sbmips/conf/GENERIC 940 src/sys/arch/sgimips/conf/GENERIC32_IP3x 941 src/sys/arch/shark/conf/GENERIC 942 src/sys/arch/sparc/conf/GENERIC 943 src/sys/arch/sparc/conf/GENERIC.MP 944 src/sys/arch/sparc64/conf/GENERIC 945 src/sys/arch/sparc64/conf/GENERIC.MP 946 src/sys/arch/sun2/conf/GENERIC 947 src/sys/arch/sun3/conf/GENERIC 948 src/sys/arch/vax/conf/GENERIC 949 src/sys/arch/vax/conf/GENERIC.MP 950 src/sys/arch/x68k/conf/GENERIC 951 952 src/sys/arch/playstation2/conf/GENERIC 953 954 Branch: yamt-readahead 955 Description: play with file readahead 956 Status: Terminated; merged to -current 957 Start Date: Mon Nov 14 2005 958 End Date: Wed Nov 30 2005 959 Base Tag: yamt-readahead-base3 960 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 961 Scope: src/sys 962 Notes: 963 964 Branch: yamt-uio_vmspace 965 Description: uio_lwp/uio_segflg -> uio_vmspace 966 Status: Terminated; merged to -current 967 Start Date: Mon Dec 31 2005 968 End Date: Wed Mar 1 2006 969 Base Tag: yamt-uio_vmspace-base5 970 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 971 Scope: src/sys 972 Notes: 973 974 Branch: yamt-vop 975 Description: remove several VOPs 976 Status: Terminated; merged to -current 977 Start Date: Wed Oct 19 2005 978 End Date: Wed Nov 2 2005 979 Base Tag: yamt-vop-base3 980 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 981 Scope: src/sys 982 Notes: http://mail-index.NetBSD.org/tech-kern/2005/09/27/0000.html 983 984 985 ######################################################################## 986 # Other: 987 ######################################################################## 988 989 Branch: magnum 990 Description: ?
