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 47Branch: comdex-fall-1999 48Description: Special release branch for pre-1.5 release at 49 Fall 1999 COMDEX. 50Status: Terminated 51Start Date: 52End Date: 53Base Tag: comdex-fall-1999-base 54Maintainer: mycroft 55Scope: Entire tree. 56Notes: 57 58Branch: netbsd-0-9 59Description: The NetBSD 0.9 release branch 60Status: Terminated 61Start Date: 62End Date: 63Base Tag: netbsd-0-9-base 64Maintainer: Release Engineering <releng@NetBSD.org> 65Scope: Entire tree. 66Notes: 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 70Branch: netbsd-1-0 71Description: The NetBSD 1.0 release branch 72Status: Terminated 73Start Date: 74End Date: 75Base Tag: netbsd-1-0-base 76Maintainer: Release Engineering <releng@NetBSD.org> 77Scope: Entire tree. 78Notes: 79 Commits restricted to release engineering. 80 81Branch: netbsd-1-1 82Description: The NetBSD 1.1 release branch 83Status: Terminated 84Start Date: 85End Date: 86Base Tag: netbsd-1-1-base 87Maintainer: Release Engineering <releng@NetBSD.org> 88Scope: Entire tree. 89Notes: 90 Commits restricted to release engineering. 91 92Branch: netbsd-1-2 93Description: The NetBSD 1.2 release branch 94Status: Terminated 95Start Date: 96End Date: 97Base Tag: netbsd-1-2-base 98Maintainer: Release Engineering <releng@NetBSD.org> 99Scope: Entire tree. 100Notes: 101 Commits restricted to release engineering. 102 103Branch: netbsd-1-3 104Description: The NetBSD 1.3 release branch 105Status: Terminated 106Start Date: 107End Date: 108Base Tag: netbsd-1-3-base 109Maintainer: Release Engineering <releng@NetBSD.org> 110Scope: Entire tree. 111Notes: 112 Commits restricted to release engineering. 113 114Branch: netbsd-1-4 115Description: The NetBSD 1.4 release branch 116Status: Terminated 117Start Date: 1 Apr 2000 118End Date: 119Base Tag: netbsd-1-4-base 120Maintainer: 1.4 Release Engineering <releng-1-4@NetBSD.org> 121Scope: Entire tree. 122Notes: 123 Commits restricted to release engineering. 124 125Branch: netbsd-1-5 126Description: The NetBSD 1.5 release branch 127Status: Terminated 128Start Date: 20 Jun 2000 129End Date: 26 Jan 2005 130Base Tag: netbsd-1-5-base 131Maintainer: 1.5 Release Engineering <releng-1-5@NetBSD.org> 132Scope: Entire tree. 133Notes: 134 Commits restricted to release engineering. 135 136Branch: netbsd-1-6 137Description: The NetBSD 1.6 release branch 138Status: Terminated 139Start Date: 22 May 2002 140End Date: 141Base Tag: netbsd-1-6-base 142Maintainer: 1.6 Release Engineering <releng-1-6@NetBSD.org> 143Scope: Entire tree. 144Notes: 145 Commits restricted to Release Engineering. 146 147Branch: netbsd-2 148Description: The NetBSD 2 release branch 149Status: Terminated 150Start Date: 23 Dec 2004 151End Date: 152Base Tag: netbsd-2-base 153Maintainer: 2 Release Engineering <releng-2@NetBSD.org> 154Scope: Entire tree.

About 1/2 of the 372 drivers are converted, the remaining 1/2 need more changes. 373 374 As of import this is snapshot of work in progress and so 375 may not compile; in particular the midi changes are very 376 much "in progress". The audio component has been tested 377 and verified to work with emuxki and auvia. There may 378 be a locking issue in the ac97 code at boot. 379 380 The are two locks per device instance, an ISR lock and 381 a character device lock. The ISR lock replaces calls to 382 splaudio()/splx(), and will be held across calls to device 383 methods which were called at splaudio() before (e.g. 384 trigger_output). The character device lock is held across 385 calls to nearly all of the methods, excluding some only 386 used for initialization, e.g. get_locks. This needs to be 387 documented at merge time. 388 389 To test on a multi way x86 system, search for "mpsafe" in 390 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 391 that will acquire the ISR lock (depends on the hardware, but 392 "while true; do mixerctl -a > /dev/null; done" may suffice). 393 Play audio, run lockstat and verify that that there is 394 contention on the ISR lock. 395 396Branch: ad-audiomp2 397Description: Add MP locking to the audio drivers 398Status: Terminated 399Start Date: 7 December 2008 400End Date: 19 November 2011 401Base Tag: ad-audiomp2-base 402Maintainer: Andrew Doran <ad@NetBSD.org> 403Scope: kernel 404Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 405 406Branch: ad-namecache 407Description: Redo the namecache 408Status: Active 409Start Date: 8 January 2020 410End Date: 411Base Tag: ad-namecache-base 412Maintainer: Andrew Doran <ad@NetBSD.org> 413Scope: src/sys src/common 414Notes: 1) Redo the namecache to focus on per-directory data 415 structures, removing the huge hashtable and nasty locking 416 scheme. 417 418 Initially this uses rbtrees (because that's what's there). 419 The intent is that ultimately some other data structure 420 will be used. 421 422 2) Experiment with having namei() traverse the cache and 423 avoid vnode locks except for the leaf in the totally 424 in-cache case. 425 426Branch: agc-netpgp-standalone 427Description: Remove dependency on openssl libraries in netpgp 428Status: Active 429Start Date: 5 May 2012 430End Date: 431Base Tag: agc-netpgp-standalone-base 432Maintainer: Alistair Crooks <agc@NetBSD.org> 433Scope: src/crypto/external/bsd/netpgp 434Notes: This branch is used to develop the version of netpgp 435 which has its own version of bignum, ciphers, and signatures 436 libraries, so that it is able to operate without openssl 437 being in place. 438 439Branch: agc-symver 440Description: Add library symbol versioning information 441Status: Active 442Start Date: 24 March 2013 443End Date: 444Base Tag: agc-symver-base 445Maintainer: Alistair Crooks <agc@NetBSD.org> 446Scope: src 447Notes: This branch is used to develop DSO symbol versioning, allowing 448 symbols to be added, modified and removed from shared libraries. 449 450Branch: bjh21-hydra 451Description: Simtec Hydra support and ARM SMP in general 452Status: Dormant 453Start Date: 18 Oct 2002 454End Date: 455Base Tag: bjh21-hydra-base 456Maintainer: Ben Harris <bjh21@NetBSD.org> 457Scope: sys/arch/arm sys/arch/acorn32 458Notes: This code was on a branch because it involves changes to 459 cpuswitch.S which would otherwise make merging the 460 nathanw_sa branch difficult. 461 462Branch: bouyer-socketcan 463Description: Implement a CAN socket layer compatible with linux SocketCAN 464Status: Terminated 465Start Date: Sun Jan 15 2017 466End Date: May 27 2017 467Base Tag: bouyer-socketcan-base 468Maintainer: Manuel Bouyer <bouyer@NetBSD.org> 469Scope: src/ 470Notes: Some documentation on SocketCAN is there: 471 https://www.kernel.org/doc/Documentation/networking/can.txt 472 473Branch: cherry-xenmp 474Description: Port i386 and amd64 Xen kernels to run MP 475Status: Terminated 476Start Date: 1st June 2011 477End Date: 13th January 2012 478Base Tag: cherry-xenmp-base 479Maintainer: Cherry G.

If you plan to 727 continue this branch, sys/netinet/in_pcb.h already contains 728 the proposed structure layout (which was roughly discussed 729 in the tech-net mailing list). 730 I also defined INP_*() macros to mimicate FreeBSD's inpcb 731 locking style, but currently they do nothing and are not 732 yet called at the correct places (needs discussion about 733 kernel fine-grained locking). 734 To continue this branch, one needs to read all the relevant 735 inpcb/in6pcb source files and change the function names, 736 structure names, structure fields according to the new 737 layout (in6pcb is gone). 738 Don't try to build a kernel from this branch because it won't 739 work. The missing pieces required to do a complete build 740 were not committed because they were incomplete and generated 741 panics. 742 You shouldn't need to worry about KAME syncs because 743 they did most of them by now. 744 After the work is done, you are required to test the branch 745 (before the merge to -current) with an interop IPv6 test. 746 More info at: http://www.tahi.org/ 747 748Branch: thorpej-cfargs 749Description: Clean up how arguments are passed to various autoconfiguration 750 routines. 751Status: Merged 752Start Date: Sat March 20 2021 753End Date: Sat April 24 2021 754Base Tag: thorpej-cfargs-base 755Maintainer: Jason Thorpe <thorpej@netbsd.org> 756Scope: src/sys 757Notes: 758 759Branch: thorpej-cfargs2 760Description: Address complaints regarding the use of variadic arguments in 761 thorpej-cfargs. 762Status: Merged 763Start Date: Sun Aug 1 2021 764End Date: Sat Aug 7 2021 765Base Tag: thorpej-cfargs2-base 766Maintainer: Jason Thorpe <thorpej@netbsd.org> 767Scope: src/sys 768Notes: 769 770Branch: thorpej-futex 771Description: Overhaul of futex operations to fix thread priority issues 772Status: Partially merged 773Start Date: Sun Nov 1 2020 774End Date: Sun Aug 19 2021 775Base Tag: thorpej-futex-base 776Maintainer: Jason Thorpe <thorpej@netbsd.org> 777Scope: src/sys src/tests/lib/libc/sys src/distrib/sets/lists 778Notes: Normal futex operations pass the test suite, but there are 779 issues with Linux compatibility currently, that need to be 780 addressed before merging.

In terms of UBC, the primary cache for 1828 file data is the VM cache, which needs to operate 1829 in terms of VM pages. As no existing device has native 1830 pages the same size as our VM pages, there already is 1831 a mapping going on between the VM system and the 1832 underlying blocks. So it would be easier and cleaner 1833 to adjust that to deal w/ different block sizes. 1834 Also with UBC, all i/o is in terms of bytes at an offset 1835 with a certain length, so the exact block size isn't a big 1836 deal. 1837 1838 Any other wrstuden-devbsize tag may (and should) go away. 1839 1840Branch: yamt-idlelwp 1841Description: idle lwp, and some changes depending on it. 1842 1843 1. separate context switching and thread scheduling. 1844 (cf. gmcgarry_ctxsw) 1845 2. implement idle lwp. 1846 3. clean up related MD/MI interfaces. 1847 4. make scheduler(s) modular. 1848 1849Status: Terminated; merged to -current 1850Start Date: Fri Feb 17 2007 1851End Date: Thu May 17 2007 1852Base Tag: yamt-idlelwp-base8 1853Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1854Scope: src/sys (src/common is tagged but not branched) 1855Notes: 1856 Status of ports: 1857 alpha [ Done, UP tested, MP not tested ] 1858 i386 [ Done, tested ] 1859 amd64 [ Done, tested ] 1860 mips [ Done, both MIPS1 and MIPS3 tested] 1861 sparc [ Done, UP tested, MP might have 1862 some problem after newlock2 merge ] 1863 sparc64 [ Done, tested ] 1864 arm [ Done, SA1 tested.
