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: agc-netpgp-standalone 385Description: Remove dependency on openssl libraries in netpgp 386Status: Active 387Start Date: 5 May 2012 388End Date: 389Base Tag: agc-netpgp-standalone-base 390Maintainer: Alistair Crooks <agc@NetBSD.org> 391Scope: src/crypto/external/bsd/netpgp 392Notes: This branch is used to develop the version of netpgp 393 which has its own version of bignum, ciphers, and signatures 394 libraries, so that it is able to operate without openssl 395 being in place. 396 397Branch: agc-symver 398Description: Add library symbol versioning information 399Status: Active 400Start Date: 24 March 2013 401End Date: 402Base Tag: agc-symver-base 403Maintainer: Alistair Crooks <agc@NetBSD.org> 404Scope: src 405Notes: This branch is used to develop DSO symbol versioning, allowing 406 symbols to be added, modified and removed from shared libraries. 407 408Branch: bjh21-hydra 409Description: Simtec Hydra support and ARM SMP in general 410Status: Dormant 411Start Date: 18 Oct 2002 412End Date: 413Base Tag: bjh21-hydra-base 414Maintainer: Ben Harris <bjh21@NetBSD.org> 415Scope: sys/arch/arm sys/arch/acorn32 416Notes: This code was on a branch because it involves changes to 417 cpuswitch.S which would otherwise make merging the 418 nathanw_sa branch difficult. 419 420Branch: bouyer-socketcan 421Description: Implement a CAN socket layer compatible with linux SocketCAN 422Status: Terminated 423Start Date: Sun Jan 15 2017 424End Date: May 27 2017 425Base Tag: bouyer-socketcan-base 426Maintainer: Manuel Bouyer <bouyer@NetBSD.org> 427Scope: src/ 428Notes: Some documentation on SocketCAN is there: 429 https://www.kernel.org/doc/Documentation/networking/can.txt 430 431Branch: cherry-xenmp 432Description: Port i386 and amd64 Xen kernels to run MP 433Status: Terminated 434Start Date: 1st June 2011 435End Date: 13th January 2012 436Base Tag: cherry-xenmp-base 437Maintainer: Cherry G.

If you plan to 673 continue this branch, sys/netinet/in_pcb.h already contains 674 the proposed structure layout (which was roughly discussed 675 in the tech-net mailing list). 676 I also defined INP_*() macros to mimicate FreeBSD's inpcb 677 locking style, but currently they do nothing and are not 678 yet called at the correct places (needs discussion about 679 kernel fine-grained locking). 680 To continue this branch, one needs to read all the relevant 681 inpcb/in6pcb source files and change the function names, 682 structure names, structure fields according to the new 683 layout (in6pcb is gone). 684 Don't try to build a kernel from this branch because it won't 685 work. The missing pieces required to do a complete build 686 were not committed because they were incomplete and generated 687 panics. 688 You shouldn't need to worry about KAME syncs because 689 they did most of them by now. 690 After the work is done, you are required to test the branch 691 (before the merge to -current) with an interop IPv6 test. 692 More info at: http://www.tahi.org/ 693 694Branch: wrstuden-fixsa 695Description: Fix a number of issues present with Scheduler Activations. 696Status: Active 697Start Date: 15 May 2007 698End Date: 699Base Tag: wrstuden-fixsa-base 700Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 701Scope: src, though all the interesting stuff is in the kernel 702 or lib/libpthread or maybe gdb. 703Notes: This branch is based off of the netbsd-4 branch! 704 This branch is intended to stage improvements for the 705 Scheduler Activations system for NetBSD 4.

In terms of UBC, the primary cache for 1680 file data is the VM cache, which needs to operate 1681 in terms of VM pages. As no existing device has native 1682 pages the same size as our VM pages, there already is 1683 a mapping going on between the VM system and the 1684 underlying blocks. So it would be easier and cleaner 1685 to adjust that to deal w/ different block sizes. 1686 Also with UBC, all i/o is in terms of bytes at an offset 1687 with a certain length, so the exact block size isn't a big 1688 deal. 1689 1690 Any other wrstuden-devbsize tag may (and should) go away. 1691 1692Branch: yamt-idlelwp 1693Description: idle lwp, and some changes depending on it. 1694 1695 1. separate context switching and thread scheduling. 1696 (cf. gmcgarry_ctxsw) 1697 2. implement idle lwp. 1698 3. clean up related MD/MI interfaces. 1699 4. make scheduler(s) modular. 1700 1701Status: Terminated; merged to -current 1702Start Date: Fri Feb 17 2007 1703End Date: Thu May 17 2007 1704Base Tag: yamt-idlelwp-base8 1705Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1706Scope: src/sys (src/common is tagged but not branched) 1707Notes: 1708 Status of ports: 1709 alpha [ Done, UP tested, MP not tested ] 1710 i386 [ Done, tested ] 1711 amd64 [ Done, tested ] 1712 mips [ Done, both MIPS1 and MIPS3 tested] 1713 sparc [ Done, UP tested, MP might have 1714 some problem after newlock2 merge ] 1715 sparc64 [ Done, tested ] 1716 arm [ Done, SA1 tested.
