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 350 drivers are converted, the remaining 1/2 need more changes. 351 352 As of import this is snapshot of work in progress and so 353 may not compile; in particular the midi changes are very 354 much "in progress". The audio component has been tested 355 and verified to work with emuxki and auvia. There may 356 be a locking issue in the ac97 code at boot. 357 358 The are two locks per device instance, an ISR lock and 359 a character device lock. The ISR lock replaces calls to 360 splaudio()/splx(), and will be held across calls to device 361 methods which were called at splaudio() before (e.g. 362 trigger_output). The character device lock is held across 363 calls to nearly all of the methods, excluding some only 364 used for initialization, e.g. get_locks. This needs to be 365 documented at merge time. 366 367 To test on a multi way x86 system, search for "mpsafe" in 368 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 369 that will acquire the ISR lock (depends on the hardware, but 370 "while true; do mixerctl -a > /dev/null; done" may suffice). 371 Play audio, run lockstat and verify that that there is 372 contention on the ISR lock. 373 374 Branch: ad-audiomp2 375 Description: Add MP locking to the audio drivers 376 Status: Terminated 377 Start Date: 7 December 2008 378 End Date: 19 November 2011 379 Base Tag: ad-audiomp2-base 380 Maintainer: Andrew Doran <ad (a] NetBSD.org> 381 Scope: kernel 382 Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 383 384 Branch: ad-namecache 385 Description: Redo the namecache 386 Status: Active 387 Start Date: 8 January 2020 388 End Date: 389 Base Tag: ad-namecache-base 390 Maintainer: Andrew Doran <ad (a] NetBSD.org> 391 Scope: src/sys src/common 392 Notes: 1) Redo the namecache to focus on per-directory data 393 structures, removing the huge hashtable and nasty locking 394 scheme. 395 396 Initially this uses rbtrees (because that's what's there). 397 The intent is that ultimately some other data structure 398 will be used. 399 400 2) Experiment with having namei() traverse the cache and 401 avoid vnode locks except for the leaf in the totally 402 in-cache case. 403 404 Branch: agc-netpgp-standalone 405 Description: Remove dependency on openssl libraries in netpgp 406 Status: Active 407 Start Date: 5 May 2012 408 End Date: 409 Base Tag: agc-netpgp-standalone-base 410 Maintainer: Alistair Crooks <agc (a] NetBSD.org> 411 Scope: src/crypto/external/bsd/netpgp 412 Notes: This branch is used to develop the version of netpgp 413 which has its own version of bignum, ciphers, and signatures 414 libraries, so that it is able to operate without openssl 415 being in place. 416 417 Branch: agc-symver 418 Description: Add library symbol versioning information 419 Status: Active 420 Start Date: 24 March 2013 421 End Date: 422 Base Tag: agc-symver-base 423 Maintainer: Alistair Crooks <agc (a] NetBSD.org> 424 Scope: src 425 Notes: This branch is used to develop DSO symbol versioning, allowing 426 symbols to be added, modified and removed from shared libraries. 427 428 Branch: bjh21-hydra 429 Description: Simtec Hydra support and ARM SMP in general 430 Status: Dormant 431 Start Date: 18 Oct 2002 432 End Date: 433 Base Tag: bjh21-hydra-base 434 Maintainer: Ben Harris <bjh21 (a] NetBSD.org> 435 Scope: sys/arch/arm sys/arch/acorn32 436 Notes: This code was on a branch because it involves changes to 437 cpuswitch.S which would otherwise make merging the 438 nathanw_sa branch difficult. 439 440 Branch: bouyer-socketcan 441 Description: Implement a CAN socket layer compatible with linux SocketCAN 442 Status: Terminated 443 Start Date: Sun Jan 15 2017 444 End Date: May 27 2017 445 Base Tag: bouyer-socketcan-base 446 Maintainer: Manuel Bouyer <bouyer (a] NetBSD.org> 447 Scope: src/ 448 Notes: Some documentation on SocketCAN is there: 449 https://www.kernel.org/doc/Documentation/networking/can.txt 450 451 Branch: cherry-xenmp 452 Description: Port i386 and amd64 Xen kernels to run MP 453 Status: Terminated 454 Start Date: 1st June 2011 455 End Date: 13th January 2012 456 Base Tag: cherry-xenmp-base 457 Maintainer: Cherry G.

If you plan to 705 continue this branch, sys/netinet/in_pcb.h already contains 706 the proposed structure layout (which was roughly discussed 707 in the tech-net mailing list). 708 I also defined INP_*() macros to mimicate FreeBSD's inpcb 709 locking style, but currently they do nothing and are not 710 yet called at the correct places (needs discussion about 711 kernel fine-grained locking). 712 To continue this branch, one needs to read all the relevant 713 inpcb/in6pcb source files and change the function names, 714 structure names, structure fields according to the new 715 layout (in6pcb is gone). 716 Don't try to build a kernel from this branch because it won't 717 work. The missing pieces required to do a complete build 718 were not committed because they were incomplete and generated 719 panics. 720 You shouldn't need to worry about KAME syncs because 721 they did most of them by now. 722 After the work is done, you are required to test the branch 723 (before the merge to -current) with an interop IPv6 test. 724 More info at: http://www.tahi.org/ 725 726 Branch: thorpej-futex 727 Description: Overhaul of futex operations to fix thread priority issues 728 Status: Active 729 Start Date: Sun Nov 1 2020 730 End Date: 731 Base Tag: thorpej-futex-base 732 Maintainer: Jason Thorpe <thorpej (a] netbsd.org> 733 Scope: src/sys src/tests/lib/libc/sys src/distrib/sets/lists 734 Note: Normal futex operataions pass the test suite, but there are 735 issues with Linux compatibility currently, that need to be 736 addressed before merging.

In terms of UBC, the primary cache for 1729 file data is the VM cache, which needs to operate 1730 in terms of VM pages. As no existing device has native 1731 pages the same size as our VM pages, there already is 1732 a mapping going on between the VM system and the 1733 underlying blocks. So it would be easier and cleaner 1734 to adjust that to deal w/ different block sizes. 1735 Also with UBC, all i/o is in terms of bytes at an offset 1736 with a certain length, so the exact block size isn't a big 1737 deal. 1738 1739 Any other wrstuden-devbsize tag may (and should) go away. 1740 1741 Branch: yamt-idlelwp 1742 Description: idle lwp, and some changes depending on it. 1743 1744 1. separate context switching and thread scheduling. 1745 (cf. gmcgarry_ctxsw) 1746 2. implement idle lwp. 1747 3. clean up related MD/MI interfaces. 1748 4. make scheduler(s) modular. 1749 1750 Status: Terminated; merged to -current 1751 Start Date: Fri Feb 17 2007 1752 End Date: Thu May 17 2007 1753 Base Tag: yamt-idlelwp-base8 1754 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 1755 Scope: src/sys (src/common is tagged but not branched) 1756 Notes: 1757 Status of ports: 1758 alpha [ Done, UP tested, MP not tested ] 1759 i386 [ Done, tested ] 1760 amd64 [ Done, tested ] 1761 mips [ Done, both MIPS1 and MIPS3 tested] 1762 sparc [ Done, UP tested, MP might have 1763 some problem after newlock2 merge ] 1764 sparc64 [ Done, tested ] 1765 arm [ Done, SA1 tested.
