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 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 374Branch: ad-audiomp2 375Description: Add MP locking to the audio drivers 376Status: Terminated 377Start Date: 7 December 2008 378End Date: 19 November 2011 379Base Tag: ad-audiomp2-base 380Maintainer: Andrew Doran <ad@NetBSD.org> 381Scope: kernel 382Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 383 384Branch: ad-namecache 385Description: Redo the namecache 386Status: Active 387Start Date: 8 January 2020 388End Date: 389Base Tag: ad-namecache-base 390Maintainer: Andrew Doran <ad@NetBSD.org> 391Scope: src/sys src/common 392Notes: 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 404Branch: agc-netpgp-standalone 405Description: Remove dependency on openssl libraries in netpgp 406Status: Active 407Start Date: 5 May 2012 408End Date: 409Base Tag: agc-netpgp-standalone-base 410Maintainer: Alistair Crooks <agc@NetBSD.org> 411Scope: src/crypto/external/bsd/netpgp 412Notes: 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 417Branch: agc-symver 418Description: Add library symbol versioning information 419Status: Active 420Start Date: 24 March 2013 421End Date: 422Base Tag: agc-symver-base 423Maintainer: Alistair Crooks <agc@NetBSD.org> 424Scope: src 425Notes: This branch is used to develop DSO symbol versioning, allowing 426 symbols to be added, modified and removed from shared libraries. 427 428Branch: bjh21-hydra 429Description: Simtec Hydra support and ARM SMP in general 430Status: Dormant 431Start Date: 18 Oct 2002 432End Date: 433Base Tag: bjh21-hydra-base 434Maintainer: Ben Harris <bjh21@NetBSD.org> 435Scope: sys/arch/arm sys/arch/acorn32 436Notes: 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 440Branch: bouyer-socketcan 441Description: Implement a CAN socket layer compatible with linux SocketCAN 442Status: Terminated 443Start Date: Sun Jan 15 2017 444End Date: May 27 2017 445Base Tag: bouyer-socketcan-base 446Maintainer: Manuel Bouyer <bouyer@NetBSD.org> 447Scope: src/ 448Notes: Some documentation on SocketCAN is there: 449 https://www.kernel.org/doc/Documentation/networking/can.txt 450 451Branch: cherry-xenmp 452Description: Port i386 and amd64 Xen kernels to run MP 453Status: Terminated 454Start Date: 1st June 2011 455End Date: 13th January 2012 456Base Tag: cherry-xenmp-base 457Maintainer: Cherry G.

If you plan to 704 continue this branch, sys/netinet/in_pcb.h already contains 705 the proposed structure layout (which was roughly discussed 706 in the tech-net mailing list). 707 I also defined INP_*() macros to mimicate FreeBSD's inpcb 708 locking style, but currently they do nothing and are not 709 yet called at the correct places (needs discussion about 710 kernel fine-grained locking). 711 To continue this branch, one needs to read all the relevant 712 inpcb/in6pcb source files and change the function names, 713 structure names, structure fields according to the new 714 layout (in6pcb is gone). 715 Don't try to build a kernel from this branch because it won't 716 work. The missing pieces required to do a complete build 717 were not committed because they were incomplete and generated 718 panics. 719 You shouldn't need to worry about KAME syncs because 720 they did most of them by now. 721 After the work is done, you are required to test the branch 722 (before the merge to -current) with an interop IPv6 test. 723 More info at: http://www.tahi.org/ 724 725Branch: wrstuden-fixsa 726Description: Fix a number of issues present with Scheduler Activations. 727Status: Active 728Start Date: 15 May 2007 729End Date: 730Base Tag: wrstuden-fixsa-base 731Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 732Scope: src, though all the interesting stuff is in the kernel 733 or lib/libpthread or maybe gdb. 734Notes: This branch is based off of the netbsd-4 branch! 735 This branch is intended to stage improvements for the 736 Scheduler Activations system for NetBSD 4. Improvements 737 include not allocating memory while preparing to tsleep(), 738 reducing inappropriate upcall delivery (hopefully also 739 eliminating the need to mlock stacks), and being 740 able to pthread_kill() running threads. At this date, 741 most goals have been achieved.

In terms of UBC, the primary cache for 1711 file data is the VM cache, which needs to operate 1712 in terms of VM pages. As no existing device has native 1713 pages the same size as our VM pages, there already is 1714 a mapping going on between the VM system and the 1715 underlying blocks. So it would be easier and cleaner 1716 to adjust that to deal w/ different block sizes. 1717 Also with UBC, all i/o is in terms of bytes at an offset 1718 with a certain length, so the exact block size isn't a big 1719 deal. 1720 1721 Any other wrstuden-devbsize tag may (and should) go away. 1722 1723Branch: yamt-idlelwp 1724Description: idle lwp, and some changes depending on it. 1725 1726 1. separate context switching and thread scheduling. 1727 (cf. gmcgarry_ctxsw) 1728 2. implement idle lwp. 1729 3. clean up related MD/MI interfaces. 1730 4. make scheduler(s) modular. 1731 1732Status: Terminated; merged to -current 1733Start Date: Fri Feb 17 2007 1734End Date: Thu May 17 2007 1735Base Tag: yamt-idlelwp-base8 1736Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1737Scope: src/sys (src/common is tagged but not branched) 1738Notes: 1739 Status of ports: 1740 alpha [ Done, UP tested, MP not tested ] 1741 i386 [ Done, tested ] 1742 amd64 [ Done, tested ] 1743 mips [ Done, both MIPS1 and MIPS3 tested] 1744 sparc [ Done, UP tested, MP might have 1745 some problem after newlock2 merge ] 1746 sparc64 [ Done, tested ] 1747 arm [ Done, SA1 tested.

It is necessary 2101 for the newlock branch, making the scheduler SMP friendly, 2102 adding real-time scheduler extensions, and reducing the 2103 number of code paths for LWP and proc switching. 2104 2105Branch: nick-hppapmap 2106Description: Update of hppa pmap with OpenBSD code. 2107Status: Terminated; merged to -current 2108Start Date: 27 October 2008 2109End Date: 30 April 2009 2110Base Tag: nick-hppapmap-base3 2111Maintainer: Nick Hudson <skrll@NetBSD.org> 2112Scope: sys/ 2113Notes: Port of the OpenBSD pmap including support for PA2.0 CPUs in 2114 32-bit mode. 2115 2116Branch: thorpej-atomic 2117Description: Implementation of an atomic memory operations API modeled 2118 after the one in Solaris 10. 2119Status: Terminated; merged to -current 2120Start Date: Apr 11 2007 2121End Date: Nov 18 2007 2122Base tag: thorpej-atomic-base 2123Maintainer: Jason Thorpe <thorpej@netbsd.org> 2124Scope: src/common 2125 src/sys 2126Notes: Base atomic primitives need to be implemented for 2127 all of the supported architectures: 2128 2129 alpha DONE 2130 arm DONE 2131 hppa 2132 i386 DONE 2133 ia64 2134 m68k DONE (except for 68010) 2135 mips 2136 ns32k 2137 powerpc DONE except for membar_*() 2138 powerpc64 DONE except for membar_*() 2139 sh3 2140 sparc DONE except for membar_*() 2141 sparc64 DONE except for membar_*() 2142 vax 2143 x86_64 DONE 2144 2145 Tested: 2146 2147 alpha NO 2148 arm NO 2149 hppa NO 2150 i386 NO 2151 ia64 NO 2152 m68k NO 2153 mips NO 2154 ns32k NO 2155 powerpc NO 2156 powerpc64 NO 2157 sh3 NO 2158 sparc NO 2159 sparc64 NO 2160 vax NO 2161 x86_64 NO 2162 2163 TODO: 2164 2165 all - Need to replace mb_*() with membar_*(). 2166 2167 - Audit MUTEX_CAS() and RWLOCK_CAS() uses 2168 to see of membar_enter() is required here. 2169 2170 - Talk to ad@ -- figure out of non-atomic 2171 mutex / rwlock release is actually safe. 2172 2173 arm - Consider using a RAS technique like 2174 MIPS uses for _lock_cas() and the mutex 2175 stubs.
