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 36 # Release branches: 37 38 Branch: comdex-fall-1999 39 Description: Special release branch for pre-1.5 release at 40 Fall 1999 COMDEX. 41 Status: Terminated 42 Start Date: 43 End Date: 44 Base Tag: comdex-fall-1999-base 45 Maintainer: ? 46 Scope: Entire tree. 47 Notes: 48 49 Branch: netbsd-0-9 50 Description: The NetBSD 0.9 release branch 51 Status: Terminated 52 Start Date: 53 End Date: 54 Base Tag: netbsd-0-9-base 55 Maintainer: Release Engineering <releng (a] netbsd.org> 56 Scope: Entire tree. 57 Notes: Subsidiary tags of: netbsd-0-9-ALPHA, netbsd-0-9-ALPHA2, 58 netbsd-0-9-BETA, netbsd-0-9-RELEASE. 59 Commits restricted to release engineering. 60 61 Branch: netbsd-1-0 62 Description: The NetBSD 1.0 release branch 63 Status: Terminated 64 Start Date: 65 End Date: 66 Base Tag: netbsd-1-0-base 67 Maintainer: Release Engineering <releng (a] netbsd.org> 68 Scope: Entire tree. 69 Notes: 70 Commits restricted to release engineering. 71 72 Branch: netbsd-1-1 73 Description: The NetBSD 1.1 release branch 74 Status: Terminated 75 Start Date: 76 End Date: 77 Base Tag: netbsd-1-1-base 78 Maintainer: Release Engineering <releng (a] netbsd.org> 79 Scope: Entire tree. 80 Notes: 81 Commits restricted to release engineering. 82 83 Branch: netbsd-1-2 84 Description: The NetBSD 1.2 release branch 85 Status: Terminated 86 Start Date: 87 End Date: 88 Base Tag: netbsd-1-2-base 89 Maintainer: Release Engineering <releng (a] netbsd.org> 90 Scope: Entire tree. 91 Notes: 92 Commits restricted to release engineering. 93 94 Branch: netbsd-1-3 95 Description: The NetBSD 1.3 release branch 96 Status: Terminated 97 Start Date: 98 End Date: 99 Base Tag: netbsd-1-3-base 100 Maintainer: Release Engineering <releng (a] netbsd.org> 101 Scope: Entire tree. 102 Notes: 103 Commits restricted to release engineering. 104 105 Branch: netbsd-1-4 106 Description: The NetBSD 1.4 release branch 107 Status: Active 108 Start Date: 1 Apr 2000 109 End Date: 110 Base Tag: netbsd-1-4-base 111 Maintainer: 1.4 Release Engineering <releng-1-4 (a] netbsd.org> 112 Scope: Entire tree. 113 Notes: 114 Commits restricted to release engineering. 115 116 Branch: netbsd-1-5 117 Description: The NetBSD 1.5 release branch 118 Status: Active 119 Start Date: 20 Jun 2000 120 End Date: 121 Base Tag: netbsd-1-5-base 122 Maintainer: 1.5 Release Engineering <releng-1-5 (a] netbsd.org> 123 Scope: Entire tree. 124 Notes: 125 Commits restricted to release engineering. 126 127 Branch: netbsd-1-6 128 Description: The NetBSD 1.6 release branch 129 Status: Active 130 Start Date: 22 May 2002 131 End Date: 132 Base Tag: netbsd-1-6-base 133 Maintainer: 1.6 Release Engineering <releng-1-6 (a] netbsd.org> 134 Scope: Entire tree. 135 Notes: 136 Commits restricted to Release Engineering. 137 138 139 # Individual developers' branches: 140 141 142 Branch: bjh21-hydra 143 Description: Simtec Hydra support and ARM SMP in general 144 Status: Active 145 Start Date: 18 Oct 2002 146 End Date: 147 Base Tag: bjh21-hydra-base 148 Maintainer: Ben Harris <bjh21 (a] netbsd.org> 149 Scope: sys/arch/arm sys/arch/acorn32 150 Notes: This code is on a branch because it involves changes to 151 cpuswitch.S which would otherwise make merging the 152 nathanw_sa branch difficult.

In terms of UBC, the primary cache for 546 file data is the VM cache, which needs to operate 547 in terms of VM pages. As no existing device has native 548 pages the same size as our VM pages, there already is 549 a mapping going on between the VM system and the 550 underlying blocks. So it would be easier and cleaner 551 to adjust that to deal w/ different block sizes. 552 Also with UBC, all i/o is in terms of bytes at an offset 553 with a certain length, so the exact block size isn't a big 554 deal. 555 556 Any other wrstuden-devbsize tag may (and should) go away. 557 558 559 560 # Other: 561 562 Branch: magnum 563 Description: ? 564 Status: ? 565 Start Date: 566 End Date: 567 Base Tag: magnum-base 568 Maintainer: ? 569 Scope: kernel 570 Notes: 571
