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 839 file data is the VM cache, which needs to operate 840 in terms of VM pages. As no existing device has native 841 pages the same size as our VM pages, there already is 842 a mapping going on between the VM system and the 843 underlying blocks. So it would be easier and cleaner 844 to adjust that to deal w/ different block sizes. 845 Also with UBC, all i/o is in terms of bytes at an offset 846 with a certain length, so the exact block size isn't a big 847 deal. 848 849 Any other wrstuden-devbsize tag may (and should) go away. 850 851 Branch: yamt-km, yamt-km-doc 852 Description: simplify/improve kernel memory management and bootstrap 853 Status: Terminated; merged to -current 854 Start Date: Tue Jan 25 2005 855 End Date: Fri Apr 1 2005 856 Base Tag: yamt-km-base{,2,3,4}, yamt-km-doc-base 857 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 858 Scope: yamt-km: src/sys 859 yamt-km-doc: src/share/man/man9/uvm.9 860 Notes: http://mail-index.NetBSD.org/tech-kern/2004/12/25/0005.html 861 862 the followings are per-port status. 863 (account names mean "tested by".) 864 865 works enough to go to multiuser: 866 alpha, i386, xen (yamt@) 867 pc532 (simonb@) 868 alpha, i386, mac68k, macppc, pmax, shark, 869 sparc, sparc64, sun3, x68k (chs@) 870 cobalt, dreamcast, hp300, news68k, newsmips, 871 sun3x (tsutsui@) 872 amiga (mhitch@) 873 cats, hp700 (skrll@) 874 xen (bouyer@) 875 876 known to have the same problem as trunk: 877 vax (chs@, stuck while running kvm_mkdb) 878 879 known to have a problem: 880 luna68k (and, if any, other m68k ports which use TTR) 881 needs to be revisited. 882 -> for luna68k, although not tested, 883 Sysmap has been moved to avoid kva conflict with 884 I/O ranges. 885 886 buildable: 887 src/sys/arch/acorn26/conf/GENERIC 888 src/sys/arch/acorn32/conf/GENERIC 889 src/sys/arch/algor/conf/P6032 890 src/sys/arch/alpha/conf/GENERIC 891 src/sys/arch/alpha/conf/GENERIC.MP 892 src/sys/arch/amd64/conf/GENERIC 893 src/sys/arch/amd64/conf/GENERIC.MP 894 src/sys/arch/amiga/conf/GENERIC 895 src/sys/arch/arc/conf/GENERIC 896 src/sys/arch/atari/conf/MILAN-PCIIDE 897 src/sys/arch/bebox/conf/GENERIC 898 src/sys/arch/cats/conf/GENERIC 899 src/sys/arch/cesfic/conf/GENERIC 900 src/sys/arch/cobalt/conf/GENERIC 901 src/sys/arch/dreamcast/conf/GENERIC 902 src/sys/arch/evbarm/conf/TS7200 903 src/sys/arch/evbppc/conf/WALNUT 904 src/sys/arch/evbsh3/conf/COMPUTEXEVB 905 src/sys/arch/evbsh5/conf/CAYMAN64 906 src/sys/arch/hp300/conf/GENERIC 907 src/sys/arch/hp700/conf/GENERIC 908 src/sys/arch/hpcarm/conf/JORNADA728 909 src/sys/arch/hpcmips/conf/GENERIC 910 src/sys/arch/hpcsh/conf/GENERIC 911 src/sys/arch/hpcsh/conf/HPW650PA 912 src/sys/arch/i386/conf/GENERIC 913 src/sys/arch/i386/conf/GENERIC.MP 914 src/sys/arch/i386/conf/XEN0 915 src/sys/arch/i386/conf/XENU 916 src/sys/arch/ibmnws/conf/GENERIC 917 src/sys/arch/iyonix/conf/GENERIC 918 src/sys/arch/luna68k/conf/GENERIC 919 src/sys/arch/mac68k/conf/GENERIC 920 src/sys/arch/macppc/conf/GENERIC 921 src/sys/arch/macppc/conf/GENERIC.MP 922 src/sys/arch/mipsco/conf/GENERIC 923 src/sys/arch/mmeye/conf/GENERIC 924 src/sys/arch/mvme68k/conf/GENERIC 925 src/sys/arch/netwinder/conf/GENERIC 926 src/sys/arch/news68k/conf/GENERIC 927 src/sys/arch/newsmips/conf/GENERIC 928 src/sys/arch/next68k/conf/GENERIC 929 src/sys/arch/ofppc/conf/GENERIC 930 src/sys/arch/pc532/conf/GENERIC 931 src/sys/arch/pmax/conf/GENERIC 932 src/sys/arch/prep/conf/GENERIC 933 src/sys/arch/sandpoint/conf/GENERIC 934 src/sys/arch/sbmips/conf/GENERIC 935 src/sys/arch/sgimips/conf/GENERIC32_IP3x 936 src/sys/arch/shark/conf/GENERIC 937 src/sys/arch/sparc/conf/GENERIC 938 src/sys/arch/sparc/conf/GENERIC.MP 939 src/sys/arch/sparc64/conf/GENERIC 940 src/sys/arch/sparc64/conf/GENERIC.MP 941 src/sys/arch/sun2/conf/GENERIC 942 src/sys/arch/sun3/conf/GENERIC 943 src/sys/arch/vax/conf/GENERIC 944 src/sys/arch/vax/conf/GENERIC.MP 945 src/sys/arch/x68k/conf/GENERIC 946 947 src/sys/arch/playstation2/conf/GENERIC 948 949 Branch: yamt-pdpolicy 950 Description: play with page replacement policy 951 - separate page replacement policy from the rest of kernel 952 - implement alternative replacement policy 953 - related read-ahead adjustment?
