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: mycroft 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: Terminated 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.

About 1/2 of the 327 drivers are converted, the remaining 1/2 need more changes. 328 329 As of import this is snapshot of work in progress and so 330 may not compile; in particular the midi changes are very 331 much "in progress". The audio component has been tested 332 and verified to work with emuxki and auvia. There may 333 be a locking issue in the ac97 code at boot. 334 335 The are two locks per device instance, an ISR lock and 336 a character device lock. The ISR lock replaces calls to 337 splaudio()/splx(), and will be held across calls to device 338 methods which were called at splaudio() before (e.g. 339 trigger_output). The character device lock is held across 340 calls to nearly all of the methods, excluding some only 341 used for initialization, e.g. get_locks. This needs to be 342 documented at merge time. 343 344 To test on a multi way x86 system, search for "mpsafe" in 345 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 346 that will acquire the ISR lock (depends on the hardware, but 347 "while true; do mixerctl -a > /dev/null; done" may suffice). 348 Play audio, run lockstat and verify that that there is 349 contention on the ISR lock. 350 351 Branch: ad-audiomp2 352 Description: Add MP locking to the audio drivers 353 Status: Terminated 354 Start Date: 7 December 2008 355 End Date: 19 November 2011 356 Base Tag: ad-audiomp2-base 357 Maintainer: Andrew Doran <ad (a] NetBSD.org> 358 Scope: kernel 359 Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 360 361 Branch: agc-netpgp-standalone 362 Description: Remove dependency on openssl libraries in netpgp 363 Status: Active 364 Start Date: 5 May 2012 365 End Date: 366 Base Tag: agc-netpgp-standalone-base 367 Maintainer: Alistair Crooks <agc (a] NetBSD.org> 368 Scope: src/crypto/external/bsd/netpgp 369 Notes: This branch is used to develop the version of netpgp 370 which has its own version of bignum, ciphers, and signatures 371 libraries, so that it is able to operate without openssl 372 being in place. 373 374 Branch: agc-symver 375 Description: Add library symbol versioning information 376 Status: Active 377 Start Date: 24 March 2013 378 End Date: 379 Base Tag: agc-symver-base 380 Maintainer: Alistair Crooks <agc (a] NetBSD.org> 381 Scope: src 382 Notes: This branch is used to develop DSO symbol versioning, allowing 383 symbols to be added, modified and removed from shared libraries. 384 385 Branch: bjh21-hydra 386 Description: Simtec Hydra support and ARM SMP in general 387 Status: Dormant 388 Start Date: 18 Oct 2002 389 End Date: 390 Base Tag: bjh21-hydra-base 391 Maintainer: Ben Harris <bjh21 (a] NetBSD.org> 392 Scope: sys/arch/arm sys/arch/acorn32 393 Notes: This code was on a branch because it involves changes to 394 cpuswitch.S which would otherwise make merging the 395 nathanw_sa branch difficult. 396 397 Branch: bouyer-socketcan 398 Description: Implement a CAN socket layer compatible with linux SocketCAN 399 Status: Terminated 400 Start Date: Sun Jan 15 2017 401 End Date: May 27 2017 402 Base Tag: bouyer-socketcan-base 403 Maintainer: Manuel Bouyer <bouyer (a] NetBSD.org> 404 Scope: src/ 405 Notes: Some documentation on SocketCAN is there: 406 https://www.kernel.org/doc/Documentation/networking/can.txt 407 408 Branch: cherry-xenmp 409 Description: Port i386 and amd64 Xen kernels to run MP 410 Status: Terminated 411 Start Date: 1st June 2011 412 End Date: 13th January 2012 413 Base Tag: cherry-xenmp-base 414 Maintainer: Cherry G.

If you plan to 651 continue this branch, sys/netinet/in_pcb.h already contains 652 the proposed structure layout (which was roughly discussed 653 in the tech-net mailing list). 654 I also defined INP_*() macros to mimicate FreeBSD's inpcb 655 locking style, but currently they do nothing and are not 656 yet called at the correct places (needs discussion about 657 kernel fine-grained locking). 658 To continue this branch, one needs to read all the relevant 659 inpcb/in6pcb source files and change the function names, 660 structure names, structure fields according to the new 661 layout (in6pcb is gone). 662 Don't try to build a kernel from this branch because it won't 663 work. The missing pieces required to do a complete build 664 were not committed because they were incomplete and generated 665 panics. 666 You shouldn't need to worry about KAME syncs because 667 they did most of them by now. 668 After the work is done, you are required to test the branch 669 (before the merge to -current) with an interop IPv6 test. 670 More info at: http://www.tahi.org/ 671 672 Branch: wrstuden-fixsa 673 Description: Fix a number of issues present with Scheduler Activations. 674 Status: Active 675 Start Date: 15 May 2007 676 End Date: 677 Base Tag: wrstuden-fixsa-base 678 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org> 679 Scope: src, though all the interesting stuff is in the kernel 680 or lib/libpthread or maybe gdb. 681 Notes: This branch is based off of the netbsd-4 branch! 682 This branch is intended to stage improvements for the 683 Scheduler Activations system for NetBSD 4. Improvements 684 include not allocating memory while preparing to tsleep(), 685 reducing inappropriate upcall delivery (hopefully also 686 eliminating the need to mlock stacks), and being 687 able to pthread_kill() running threads. At this date, 688 most goals have been achieved.

This branch will re-add necessary 704 upcall support, and will also serve as a chance to clean 705 out cruft that had accumulated in the implementation over 706 time. 707 708 Branch: yamt-kmem 709 Description: 710 - separate kernel va allocation from kernel fault handling. 711 - make kmem_alloc interrupt-safe. 712 Status: Active 713 Start Date: Sun Dec 9 2007 714 End Date: 715 Base Tag: yamt-kmem-base3 716 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 717 Scope: src/sys (src/common is tagged but not branched) 718 Notes: 719 todo: 720 - investigate if PMAP_PREFER equivalent can be done 721 with vmem_xalloc. find a tester with hardware for it. 722 - g/c replaced code, including kmapent and malloc. 723 - consider to remove other submaps. eg. mb_map 724 725 Branch: yamt-nfs-mp 726 Description: make nfs client mp-safe 727 Status: Active 728 Start Date: Sun Apr 27 2008 729 End Date: 730 Base Tag: yamt-nfs-mp-base11 731 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 732 Scope: src/sys (src/common is tagged but not branched) 733 Notes: 734 735 Branch: yamt-pagecache 736 Description: page cache related changes 737 Status: Active 738 Start Date: Wed Nov 2 2011 739 End Date: 740 Base Tag: yamt-pagecache-base8 741 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 742 Scope: src 743 Notes: - maintain object pages in radix tree rather than rb tree. 744 - shrink the size of vm_page. 745 - reduce unnecessary page scan in putpages. esp. when an 746 object has a ton of pages cached but only a few of them 747 are dirty. 748 - reduce the number of pmap operations by tracking page 749 dirtiness more precisely in uvm layer. 750 - fix nfs commit range tracking. 751 - fix nfs write clustering.

So it would be easier and cleaner 1644 to adjust that to deal w/ different block sizes. 1645 Also with UBC, all i/o is in terms of bytes at an offset 1646 with a certain length, so the exact block size isn't a big 1647 deal. 1648 1649 Any other wrstuden-devbsize tag may (and should) go away. 1650 1651 Branch: yamt-idlelwp 1652 Description: idle lwp, and some changes depending on it. 1653 1654 1. separate context switching and thread scheduling. 1655 (cf. gmcgarry_ctxsw) 1656 2. implement idle lwp. 1657 3. clean up related MD/MI interfaces. 1658 4. make scheduler(s) modular. 1659 1660 Status: Terminated; merged to -current 1661 Start Date: Fri Feb 17 2007 1662 End Date: Thu May 17 2007 1663 Base Tag: yamt-idlelwp-base8 1664 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 1665 Scope: src/sys (src/common is tagged but not branched) 1666 Notes: 1667 Status of ports: 1668 alpha [ Done, UP tested, MP not tested ] 1669 i386 [ Done, tested ] 1670 amd64 [ Done, tested ] 1671 mips [ Done, both MIPS1 and MIPS3 tested] 1672 sparc [ Done, UP tested, MP might have 1673 some problem after newlock2 merge ] 1674 sparc64 [ Done, tested ] 1675 arm [ Done, SA1 tested.
