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 327 drivers are converted, the remaining 1/2 need more changes. 328 329 As of import this is snapshot of work in progress and so 330 may not compile; in particular the midi changes are very 331 much "in progress". The audio component has been tested 332 and verified to work with emuxki and auvia. There may 333 be a locking issue in the ac97 code at boot. 334 335 The are two locks per device instance, an ISR lock and 336 a character device lock. The ISR lock replaces calls to 337 splaudio()/splx(), and will be held across calls to device 338 methods which were called at splaudio() before (e.g. 339 trigger_output). The character device lock is held across 340 calls to nearly all of the methods, excluding some only 341 used for initialization, e.g. get_locks. This needs to be 342 documented at merge time. 343 344 To test on a multi way x86 system, search for "mpsafe" in 345 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 346 that will acquire the ISR lock (depends on the hardware, but 347 "while true; do mixerctl -a > /dev/null; done" may suffice). 348 Play audio, run lockstat and verify that that there is 349 contention on the ISR lock. 350 351Branch: ad-audiomp2 352Description: Add MP locking to the audio drivers 353Status: Terminated 354Start Date: 7 December 2008 355End Date: 19 November 2011 356Base Tag: ad-audiomp2-base 357Maintainer: Andrew Doran <ad@NetBSD.org> 358Scope: kernel 359Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 360 361Branch: agc-netpgp-standalone 362Description: Remove dependency on openssl libraries in netpgp 363Status: Active 364Start Date: 5 May 2012 365End Date: 366Base Tag: agc-netpgp-standalone-base 367Maintainer: Alistair Crooks <agc@NetBSD.org> 368Scope: src/crypto/external/bsd/netpgp 369Notes: This branch is used to develop the version of netpgp 370 which has its own version of bignum, ciphers, and signatures 371 libraries, so that it is able to operate without openssl 372 being in place. 373 374Branch: agc-symver 375Description: Add library symbol versioning information 376Status: Active 377Start Date: 24 March 2013 378End Date: 379Base Tag: agc-symver-base 380Maintainer: Alistair Crooks <agc@NetBSD.org> 381Scope: src 382Notes: This branch is used to develop DSO symbol versioning, allowing 383 symbols to be added, modified and removed from shared libraries. 384 385Branch: bjh21-hydra 386Description: Simtec Hydra support and ARM SMP in general 387Status: Dormant 388Start Date: 18 Oct 2002 389End Date: 390Base Tag: bjh21-hydra-base 391Maintainer: Ben Harris <bjh21@NetBSD.org> 392Scope: sys/arch/arm sys/arch/acorn32 393Notes: This code was on a branch because it involves changes to 394 cpuswitch.S which would otherwise make merging the 395 nathanw_sa branch difficult. 396 397Branch: bouyer-socketcan 398Description: Implement a CAN socket layer compatible with linux SocketCAN 399Status: Active 400Start Date: Sun Jan 15 2017 401End Date: 402Base Tag: bouyer-socketcan-base 403Maintainer: Manuel Bouyer <bouyer@NetBSD.org> 404Scope: src/ 405Notes: Some documentation on SocketCAN is there: 406 https://www.kernel.org/doc/Documentation/networking/can.txt 407 408Branch: cherry-xenmp 409Description: Port i386 and amd64 Xen kernels to run MP 410Status: Terminated 411Start Date: 1st June 2011 412End Date: 13th January 2012 413Base Tag: cherry-xenmp-base 414Maintainer: Cherry G.

If you plan to 651 continue this branch, sys/netinet/in_pcb.h already contains 652 the proposed structure layout (which was roughly discussed 653 in the tech-net mailing list). 654 I also defined INP_*() macros to mimicate FreeBSD's inpcb 655 locking style, but currently they do nothing and are not 656 yet called at the correct places (needs discussion about 657 kernel fine-grained locking). 658 To continue this branch, one needs to read all the relevant 659 inpcb/in6pcb source files and change the function names, 660 structure names, structure fields according to the new 661 layout (in6pcb is gone). 662 Don't try to build a kernel from this branch because it won't 663 work. The missing pieces required to do a complete build 664 were not committed because they were incomplete and generated 665 panics. 666 You shouldn't need to worry about KAME syncs because 667 they did most of them by now. 668 After the work is done, you are required to test the branch 669 (before the merge to -current) with an interop IPv6 test. 670 More info at: http://www.tahi.org/ 671 672Branch: wrstuden-fixsa 673Description: Fix a number of issues present with Scheduler Activations. 674Status: Active 675Start Date: 15 May 2007 676End Date: 677Base Tag: wrstuden-fixsa-base 678Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 679Scope: src, though all the interesting stuff is in the kernel 680 or lib/libpthread or maybe gdb. 681Notes: This branch is based off of the netbsd-4 branch! 682 This branch is intended to stage improvements for the 683 Scheduler Activations system for NetBSD 4. Improvements 684 include not allocating memory while preparing to tsleep(), 685 reducing inappropriate upcall delivery (hopefully also 686 eliminating the need to mlock stacks), and being 687 able to pthread_kill() running threads. At this date, 688 most goals have been achieved.

So it would be easier and cleaner 1628 to adjust that to deal w/ different block sizes. 1629 Also with UBC, all i/o is in terms of bytes at an offset 1630 with a certain length, so the exact block size isn't a big 1631 deal. 1632 1633 Any other wrstuden-devbsize tag may (and should) go away. 1634 1635Branch: yamt-idlelwp 1636Description: idle lwp, and some changes depending on it. 1637 1638 1. separate context switching and thread scheduling. 1639 (cf. gmcgarry_ctxsw) 1640 2. implement idle lwp. 1641 3. clean up related MD/MI interfaces. 1642 4. make scheduler(s) modular. 1643 1644Status: Terminated; merged to -current 1645Start Date: Fri Feb 17 2007 1646End Date: Thu May 17 2007 1647Base Tag: yamt-idlelwp-base8 1648Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1649Scope: src/sys (src/common is tagged but not branched) 1650Notes: 1651 Status of ports: 1652 alpha [ Done, UP tested, MP not tested ] 1653 i386 [ Done, tested ] 1654 amd64 [ Done, tested ] 1655 mips [ Done, both MIPS1 and MIPS3 tested] 1656 sparc [ Done, UP tested, MP might have 1657 some problem after newlock2 merge ] 1658 sparc64 [ Done, tested ] 1659 arm [ Done, SA1 tested.
