1 # $NetBSD: BRANCHES,v 1.335 2015/11/11 06:53:36 snj 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: 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 316 drivers are converted, the remaining 1/2 need more changes. 317 318 As of import this is snapshot of work in progress and so 319 may not compile; in particular the midi changes are very 320 much "in progress". The audio component has been tested 321 and verified to work with emuxki and auvia. There may 322 be a locking issue in the ac97 code at boot. 323 324 The are two locks per device instance, an ISR lock and 325 a character device lock. The ISR lock replaces calls to 326 splaudio()/splx(), and will be held across calls to device 327 methods which were called at splaudio() before (e.g. 328 trigger_output). The character device lock is held across 329 calls to nearly all of the methods, excluding some only 330 used for initialization, e.g. get_locks. This needs to be 331 documented at merge time. 332 333 To test on a multi way x86 system, search for "mpsafe" in 334 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 335 that will acquire the ISR lock (depends on the hardware, but 336 "while true; do mixerctl -a > /dev/null; done" may suffice). 337 Play audio, run lockstat and verify that that there is 338 contention on the ISR lock. 339 340 Branch: ad-audiomp2 341 Description: Add MP locking to the audio drivers 342 Status: Terminated 343 Start Date: 7 December 2008 344 End Date: 19 November 2011 345 Base Tag: ad-audiomp2-base 346 Maintainer: Andrew Doran <ad (a] NetBSD.org> 347 Scope: kernel 348 Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 349 350 Branch: agc-netpgp-standalone 351 Description: Remove dependency on openssl libraries in netpgp 352 Status: Active 353 Start Date: 5 May 2012 354 End Date: 355 Base Tag: agc-netpgp-standalone-base 356 Maintainer: Alistair Crooks <agc (a] NetBSD.org> 357 Scope: src/crypto/external/bsd/netpgp 358 Notes: This branch is used to develop the version of netpgp 359 which has its own version of bignum, ciphers, and signatures 360 libraries, so that it is able to operate without openssl 361 being in place. 362 363 Branch: agc-symver 364 Description: Add library symbol versioning information 365 Status: Active 366 Start Date: 24 March 2013 367 End Date: 368 Base Tag: agc-symver-base 369 Maintainer: Alistair Crooks <agc (a] NetBSD.org> 370 Scope: src 371 Notes: This branch is used to develop DSO symbol versioning, allowing 372 symbols to be added, modified and removed from shared libraries. 373 374 Branch: bjh21-hydra 375 Description: Simtec Hydra support and ARM SMP in general 376 Status: Dormant 377 Start Date: 18 Oct 2002 378 End Date: 379 Base Tag: bjh21-hydra-base 380 Maintainer: Ben Harris <bjh21 (a] NetBSD.org> 381 Scope: sys/arch/arm sys/arch/acorn32 382 Notes: This code was on a branch because it involves changes to 383 cpuswitch.S which would otherwise make merging the 384 nathanw_sa branch difficult. 385 386 Branch: cherry-xenmp 387 Description: Port i386 and amd64 Xen kernels to run MP 388 Status: Terminated 389 Start Date: 1st June 2011 390 End Date: 13th January 2012 391 Base Tag: cherry-xenmp-base 392 Maintainer: Cherry G.

If you plan to 629 continue this branch, sys/netinet/in_pcb.h already contains 630 the proposed structure layout (which was roughly discussed 631 in the tech-net mailing list). 632 I also defined INP_*() macros to mimicate FreeBSD's inpcb 633 locking style, but currently they do nothing and are not 634 yet called at the correct places (needs discussion about 635 kernel fine-grained locking). 636 To continue this branch, one needs to read all the relevant 637 inpcb/in6pcb source files and change the function names, 638 structure names, structure fields according to the new 639 layout (in6pcb is gone). 640 Don't try to build a kernel from this branch because it won't 641 work. The missing pieces required to do a complete build 642 were not committed because they were incomplete and generated 643 panics. 644 You shouldn't need to worry about KAME syncs because 645 they did most of them by now. 646 After the work is done, you are required to test the branch 647 (before the merge to -current) with an interop IPv6 test. 648 More info at: http://www.tahi.org/ 649 650 Branch: wrstuden-fixsa 651 Description: Fix a number of issues present with Scheduler Activations. 652 Status: Active 653 Start Date: 15 May 2007 654 End Date: 655 Base Tag: wrstuden-fixsa-base 656 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org> 657 Scope: src, though all the interesting stuff is in the kernel 658 or lib/libpthread or maybe gdb. 659 Notes: This branch is based off of the netbsd-4 branch! 660 This branch is intended to stage improvements for the 661 Scheduler Activations system for NetBSD 4. Improvements 662 include not allocating memory while preparing to tsleep(), 663 reducing inappropriate upcall delivery (hopefully also 664 eliminating the need to mlock stacks), and being 665 able to pthread_kill() running threads. At this date, 666 most goals have been achieved. This branch also includes 667 fixes to gdb to support working with threaded apps. 668 669 Branch: wrstuden-revivesa 670 Description: Fix a number of issues present with Scheduler Activations. 671 Status: Active 672 Start Date: 10 May 2008 673 End Date: 674 Base Tag: wrstuden-revivesa-base 675 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org> 676 Scope: src, though all the interesting stuff is in the kernel 677 Notes: This branch is intended to revive Scheduler Activations 678 in -current in the 5.0 era. This branch's main goal is 679 to re-add syscall compatability so that SA-based libpthread 680 programs can run with a -current kernel. 1:1 threading will 681 remain the NetBSD-default. This branch will re-add necessary 682 upcall support, and will also serve as a chance to clean 683 out cruft that had accumulated in the implementation over 684 time. 685 686 Branch: yamt-kmem 687 Description: 688 - separate kernel va allocation from kernel fault handling. 689 - make kmem_alloc interrupt-safe. 690 Status: Active 691 Start Date: Sun Dec 9 2007 692 End Date: 693 Base Tag: yamt-kmem-base3 694 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 695 Scope: src/sys (src/common is tagged but not branched) 696 Notes: 697 todo: 698 - investigate if PMAP_PREFER equivalent can be done 699 with vmem_xalloc. find a tester with hardware for it. 700 - g/c replaced code, including kmapent and malloc. 701 - consider to remove other submaps. eg. mb_map 702 703 Branch: yamt-nfs-mp 704 Description: make nfs client mp-safe 705 Status: Active 706 Start Date: Sun Apr 27 2008 707 End Date: 708 Base Tag: yamt-nfs-mp-base11 709 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 710 Scope: src/sys (src/common is tagged but not branched) 711 Notes: 712 713 Branch: yamt-pagecache 714 Description: page cache related changes 715 Status: Active 716 Start Date: Wed Nov 2 2011 717 End Date: 718 Base Tag: yamt-pagecache-base8 719 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 720 Scope: src 721 Notes: - maintain object pages in radix tree rather than rb tree. 722 - shrink the size of vm_page. 723 - reduce unnecessary page scan in putpages. esp. when an 724 object has a ton of pages cached but only a few of them 725 are dirty. 726 - reduce the number of pmap operations by tracking page 727 dirtiness more precisely in uvm layer. 728 - fix nfs commit range tracking. 729 - fix nfs write clustering.
