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

In terms of UBC, the primary cache for 1660 file data is the VM cache, which needs to operate 1661 in terms of VM pages. As no existing device has native 1662 pages the same size as our VM pages, there already is 1663 a mapping going on between the VM system and the 1664 underlying blocks. So it would be easier and cleaner 1665 to adjust that to deal w/ different block sizes. 1666 Also with UBC, all i/o is in terms of bytes at an offset 1667 with a certain length, so the exact block size isn't a big 1668 deal. 1669 1670 Any other wrstuden-devbsize tag may (and should) go away. 1671 1672Branch: yamt-idlelwp 1673Description: idle lwp, and some changes depending on it. 1674 1675 1. separate context switching and thread scheduling. 1676 (cf. gmcgarry_ctxsw) 1677 2. implement idle lwp. 1678 3. clean up related MD/MI interfaces. 1679 4. make scheduler(s) modular. 1680 1681Status: Terminated; merged to -current 1682Start Date: Fri Feb 17 2007 1683End Date: Thu May 17 2007 1684Base Tag: yamt-idlelwp-base8 1685Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1686Scope: src/sys (src/common is tagged but not branched) 1687Notes: 1688 Status of ports: 1689 alpha [ Done, UP tested, MP not tested ] 1690 i386 [ Done, tested ] 1691 amd64 [ Done, tested ] 1692 mips [ Done, both MIPS1 and MIPS3 tested] 1693 sparc [ Done, UP tested, MP might have 1694 some problem after newlock2 merge ] 1695 sparc64 [ Done, tested ] 1696 arm [ Done, SA1 tested.
