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 339 drivers are converted, the remaining 1/2 need more changes. 340 341 As of import this is snapshot of work in progress and so 342 may not compile; in particular the midi changes are very 343 much "in progress". The audio component has been tested 344 and verified to work with emuxki and auvia. There may 345 be a locking issue in the ac97 code at boot. 346 347 The are two locks per device instance, an ISR lock and 348 a character device lock. The ISR lock replaces calls to 349 splaudio()/splx(), and will be held across calls to device 350 methods which were called at splaudio() before (e.g. 351 trigger_output). The character device lock is held across 352 calls to nearly all of the methods, excluding some only 353 used for initialization, e.g. get_locks. This needs to be 354 documented at merge time. 355 356 To test on a multi way x86 system, search for "mpsafe" in 357 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 358 that will acquire the ISR lock (depends on the hardware, but 359 "while true; do mixerctl -a > /dev/null; done" may suffice). 360 Play audio, run lockstat and verify that that there is 361 contention on the ISR lock. 362 363Branch: ad-audiomp2 364Description: Add MP locking to the audio drivers 365Status: Terminated 366Start Date: 7 December 2008 367End Date: 19 November 2011 368Base Tag: ad-audiomp2-base 369Maintainer: Andrew Doran <ad@NetBSD.org> 370Scope: kernel 371Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 372 373Branch: agc-netpgp-standalone 374Description: Remove dependency on openssl libraries in netpgp 375Status: Active 376Start Date: 5 May 2012 377End Date: 378Base Tag: agc-netpgp-standalone-base 379Maintainer: Alistair Crooks <agc@NetBSD.org> 380Scope: src/crypto/external/bsd/netpgp 381Notes: This branch is used to develop the version of netpgp 382 which has its own version of bignum, ciphers, and signatures 383 libraries, so that it is able to operate without openssl 384 being in place. 385 386Branch: agc-symver 387Description: Add library symbol versioning information 388Status: Active 389Start Date: 24 March 2013 390End Date: 391Base Tag: agc-symver-base 392Maintainer: Alistair Crooks <agc@NetBSD.org> 393Scope: src 394Notes: This branch is used to develop DSO symbol versioning, allowing 395 symbols to be added, modified and removed from shared libraries. 396 397Branch: bjh21-hydra 398Description: Simtec Hydra support and ARM SMP in general 399Status: Dormant 400Start Date: 18 Oct 2002 401End Date: 402Base Tag: bjh21-hydra-base 403Maintainer: Ben Harris <bjh21@NetBSD.org> 404Scope: sys/arch/arm sys/arch/acorn32 405Notes: This code was on a branch because it involves changes to 406 cpuswitch.S which would otherwise make merging the 407 nathanw_sa branch difficult. 408 409Branch: bouyer-socketcan 410Description: Implement a CAN socket layer compatible with linux SocketCAN 411Status: Terminated 412Start Date: Sun Jan 15 2017 413End Date: May 27 2017 414Base Tag: bouyer-socketcan-base 415Maintainer: Manuel Bouyer <bouyer@NetBSD.org> 416Scope: src/ 417Notes: Some documentation on SocketCAN is there: 418 https://www.kernel.org/doc/Documentation/networking/can.txt 419 420Branch: cherry-xenmp 421Description: Port i386 and amd64 Xen kernels to run MP 422Status: Terminated 423Start Date: 1st June 2011 424End Date: 13th January 2012 425Base Tag: cherry-xenmp-base 426Maintainer: Cherry G.

If you plan to 663 continue this branch, sys/netinet/in_pcb.h already contains 664 the proposed structure layout (which was roughly discussed 665 in the tech-net mailing list). 666 I also defined INP_*() macros to mimicate FreeBSD's inpcb 667 locking style, but currently they do nothing and are not 668 yet called at the correct places (needs discussion about 669 kernel fine-grained locking). 670 To continue this branch, one needs to read all the relevant 671 inpcb/in6pcb source files and change the function names, 672 structure names, structure fields according to the new 673 layout (in6pcb is gone). 674 Don't try to build a kernel from this branch because it won't 675 work. The missing pieces required to do a complete build 676 were not committed because they were incomplete and generated 677 panics. 678 You shouldn't need to worry about KAME syncs because 679 they did most of them by now. 680 After the work is done, you are required to test the branch 681 (before the merge to -current) with an interop IPv6 test. 682 More info at: http://www.tahi.org/ 683 684Branch: wrstuden-fixsa 685Description: Fix a number of issues present with Scheduler Activations. 686Status: Active 687Start Date: 15 May 2007 688End Date: 689Base Tag: wrstuden-fixsa-base 690Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 691Scope: src, though all the interesting stuff is in the kernel 692 or lib/libpthread or maybe gdb. 693Notes: This branch is based off of the netbsd-4 branch! 694 This branch is intended to stage improvements for the 695 Scheduler Activations system for NetBSD 4.

In terms of UBC, the primary cache for 1651 file data is the VM cache, which needs to operate 1652 in terms of VM pages. As no existing device has native 1653 pages the same size as our VM pages, there already is 1654 a mapping going on between the VM system and the 1655 underlying blocks. So it would be easier and cleaner 1656 to adjust that to deal w/ different block sizes. 1657 Also with UBC, all i/o is in terms of bytes at an offset 1658 with a certain length, so the exact block size isn't a big 1659 deal. 1660 1661 Any other wrstuden-devbsize tag may (and should) go away. 1662 1663Branch: yamt-idlelwp 1664Description: idle lwp, and some changes depending on it. 1665 1666 1. separate context switching and thread scheduling. 1667 (cf. gmcgarry_ctxsw) 1668 2. implement idle lwp. 1669 3. clean up related MD/MI interfaces. 1670 4. make scheduler(s) modular. 1671 1672Status: Terminated; merged to -current 1673Start Date: Fri Feb 17 2007 1674End Date: Thu May 17 2007 1675Base Tag: yamt-idlelwp-base8 1676Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1677Scope: src/sys (src/common is tagged but not branched) 1678Notes: 1679 Status of ports: 1680 alpha [ Done, UP tested, MP not tested ] 1681 i386 [ Done, tested ] 1682 amd64 [ Done, tested ] 1683 mips [ Done, both MIPS1 and MIPS3 tested] 1684 sparc [ Done, UP tested, MP might have 1685 some problem after newlock2 merge ] 1686 sparc64 [ Done, tested ] 1687 arm [ Done, SA1 tested.

It is necessary 2041 for the newlock branch, making the scheduler SMP friendly, 2042 adding real-time scheduler extensions, and reducing the 2043 number of code paths for LWP and proc switching. 2044 2045Branch: nick-hppapmap 2046Description: Update of hppa pmap with OpenBSD code. 2047Status: Terminated; merged to -current 2048Start Date: 27 October 2008 2049End Date: 30 April 2009 2050Base Tag: nick-hppapmap-base3 2051Maintainer: Nick Hudson <skrll@NetBSD.org> 2052Scope: sys/ 2053Notes: Port of the OpenBSD pmap including support for PA2.0 CPUs in 2054 32-bit mode. 2055 2056Branch: thorpej-atomic 2057Description: Implementation of an atomic memory operations API modeled 2058 after the one in Solaris 10. 2059Status: Terminated; merged to -current 2060Start Date: Apr 11 2007 2061End Date: Nov 18 2007 2062Base tag: thorpej-atomic-base 2063Maintainer: Jason Thorpe <thorpej@netbsd.org> 2064Scope: src/common 2065 src/sys 2066Notes: Base atomic primitives need to be implemented for 2067 all of the supported architectures: 2068 2069 alpha DONE 2070 arm DONE 2071 hppa 2072 i386 DONE 2073 ia64 2074 m68k DONE (except for 68010) 2075 mips 2076 ns32k 2077 powerpc DONE except for membar_*() 2078 powerpc64 DONE except for membar_*() 2079 sh3 2080 sparc DONE except for membar_*() 2081 sparc64 DONE except for membar_*() 2082 vax 2083 x86_64 DONE 2084 2085 Tested: 2086 2087 alpha NO 2088 arm NO 2089 hppa NO 2090 i386 NO 2091 ia64 NO 2092 m68k NO 2093 mips NO 2094 ns32k NO 2095 powerpc NO 2096 powerpc64 NO 2097 sh3 NO 2098 sparc NO 2099 sparc64 NO 2100 vax NO 2101 x86_64 NO 2102 2103 TODO: 2104 2105 all - Need to replace mb_*() with membar_*(). 2106 2107 - Audit MUTEX_CAS() and RWLOCK_CAS() uses 2108 to see of membar_enter() is required here. 2109 2110 - Talk to ad@ -- figure out of non-atomic 2111 mutex / rwlock release is actually safe. 2112 2113 arm - Consider using a RAS technique like 2114 MIPS uses for _lock_cas() and the mutex 2115 stubs.
