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: ? 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: Active 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 221 drivers are converted, the remaining 1/2 need more changes. 222 223 As of import this is snapshot of work in progress and so 224 may not compile; in particular the midi changes are very 225 much "in progress". The audio component has been tested 226 and verified to work with emuxki and auvia. There may 227 be a locking issue in the ac97 code at boot. 228 229 The are two locks per device instance, an ISR lock and 230 a character device lock. The ISR lock replaces calls to 231 splaudio()/splx(), and will be held across calls to device 232 methods which were called at splaudio() before (e.g. 233 trigger_output). The character device lock is held across 234 calls to nearly all of the methods, excluding some only 235 used for initialization, e.g. get_locks. This needs to be 236 documented at merge time. 237 238 To test on a multi way x86 system, search for "mpsafe" in 239 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 240 that will acquire the ISR lock (depends on the hardware, but 241 "while true; do mixerctl -a > /dev/null; done" may suffice). 242 Play audio, run lockstat and verify that that there is 243 contention on the ISR lock. 244 245Branch: bjh21-hydra 246Description: Simtec Hydra support and ARM SMP in general 247Status: Dormant 248Start Date: 18 Oct 2002 249End Date: 250Base Tag: bjh21-hydra-base 251Maintainer: Ben Harris <bjh21@NetBSD.org> 252Scope: sys/arch/arm sys/arch/acorn32 253Notes: This code was on a branch because it involves changes to 254 cpuswitch.S which would otherwise make merging the 255 nathanw_sa branch difficult. 256 257Branch: chris-arm-intr-rework 258Description: Rework arm interrupt handling code 259Status: Active 260Start Date: 11 Aug 2007 261End Date: 262Base Tag: chris-arm-intr-rework-base 263Maintainer: Chris Gilbert <chris@NetBSD.org> 264Scope: sys/arch/arm sys/arch/cats (other arm archs to follow) 265Notes: Rework arm interrupt code to provide a shared set of interrupt 266 routines, and allow improvements to be shared across all arm 267 based hardware. 268 269Branch: cube-autoconf 270Description: Renovate autoconf(9) API 271Status: Active 272Start Date: 11 Dec 2007 273End Date: 274Base Tag: cube-autoconf-base 275Maintainer: Quentin Garnier <cube@NetBSD.org> 276Scope: kernel usr.bin/config (and some other userland bits) 277Notes: Address a number of issues the current autoconf(9) API has. 278 279Branch: gmcgarry_ctxsw 280Description: Separate scheduler from context-switch code 281Status: Dormant 282Start Date: 18 December 2002 283End Date: 284Base Tag: gmcgarry_ctxsw_base 285Maintainer: Gregory McGarry <gmcgarry@NetBSD.org> 286Scope: kernel 287Notes: Removing knowledge of the scheduler and its run queues 288 from the machine-dependent context switch code is the 289 first step in cleaning up the scheduler. It is necessary 290 for the newlock branch, making the scheduler SMP friendly, 291 adding real-time scheduler extensions, and reducing the 292 number of code paths for LWP and proc switching. 293 294Branch: gmcgarry_ucred 295Description: Integrate and encapsulate user credentials 296Status: Dormant 297Start Date: 18 December 2002 298End Date: 299Base Tag: gmcgarry_ucred_base 300Maintainer: Gregory McGarry <gmcgarry@NetBSD.org> 301Scope: kernel 302Notes: merge pcred and ucred and poolify 303 304Branch: haad-dm 305Description: Add support for LVM to NetBSD 306Status: Active 307Start Date: 7 July 2008 308End Date: 309Base Tag: haad-dm-base 310Maintainer: Adam Hamsik <haad@NetBSD.org> 311Scope: kernel 312Notes: LVM support is based on Linux lvm2tools, 313 libdevmapper library and NetBSD device-mapper 314 driver. 315 316Branch: hpcarm-cleanup 317Description: Fix build problems for hpcarm 318Status: Active 319Start Date: 31 July 2007 320End Date: 321Base Tag: hpcarm-cleanup-base 322Maintainer: Robert Swindells <rjs@NetBSD.org> 323Scope: kernel 324Notes: Modify SA11x0 interrupt code to match PXA2x0 equivalent. 325 326Branch: itohy-usb1 327Description: USB stack overhaul, mostly DMA related 328Status: Active 329Start Date: 22 May 2007 330End Date: 331Base Tag: itohy-usb1-base 332Maintainer: ITOH Yasufumi <itohy@NetBSD.org> 333Scope: kernel 334Notes: To check out the kernel source tree, 335 1. check out checkout script 336 cvs checkout -ritohy-usb1 src/sys/dev/usb/filelist 337 2. update files in the branch 338 sh -e src/sys/dev/usb/filelist 339 340Branch: kame 341Description: KAME Project 342Status: Dormant 343Start Date: 28 Jun 1999 344End Date: 345Base Tag: 346Maintainer: Jun-ichiro itojun Hagino <itojun@NetBSD.org> 347Scope: kernel 348Notes: http://www.kame.net 349 Used for "reference" purposes for early part of KAME 350 integration effort.

If you plan to 467 continue this branch, sys/netinet/in_pcb.h already contains 468 the proposed structure layout (which was roughly discussed 469 in the tech-net mailing list). 470 I also defined INP_*() macros to mimicate FreeBSD's inpcb 471 locking style, but currently they do nothing and are not 472 yet called at the correct places (needs discussion about 473 kernel fine-grained locking). 474 To continue this branch, one needs to read all the relevant 475 inpcb/in6pcb source files and change the function names, 476 structure names, structure fields according to the new 477 layout (in6pcb is gone). 478 Don't try to build a kernel from this branch because it won't 479 work. The missing pieces required to do a complete build 480 were not committed because they were incomplete and generated 481 panics. 482 You shouldn't need to worry about KAME syncs because 483 they did most of them by now. 484 After the work is done, you are required to test the branch 485 (before the merge to -current) with an interop IPv6 test. 486 More info at: http://www.tahi.org/ 487 488Branch: rtr-xorg-branch 489Description: xorg & static build alterations to src/x11 490Status: Active 491Start Date: Nov 15 2004 492End Date: 493Base tag: rtr-xorg-branch-base 494Maintainer: Tyler R.

Improvements 516 include not allocating memory while preparing to tsleep(), 517 reducing inappropriate upcall delivery (hopefully also 518 eliminating the need to mlock stacks), and being 519 able to pthread_kill() running threads. At this date, 520 most goals have been achieved. This branch also includes 521 fixes to gdb to support working with threaded apps. 522 523Branch: wrstuden-revivesa 524Description: Fix a number of issues present with Scheduler Activations. 525Status: Active 526Start Date: 10 May 2008 527End Date: 528Base Tag: wrstuden-revivesa-base 529Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 530Scope: src, though all the interesting stuff is in the kernel 531Notes: This branch is intended to revive Scheduler Activations 532 in -current in the 5.0 era. This branch's main goal is 533 to re-add syscall compatability so that SA-based libpthread 534 programs can run with a -current kernel. 1:1 threading will 535 remain the NetBSD-default.

In terms of UBC, the primary cache for 1304 file data is the VM cache, which needs to operate 1305 in terms of VM pages. As no existing device has native 1306 pages the same size as our VM pages, there already is 1307 a mapping going on between the VM system and the 1308 underlying blocks. So it would be easier and cleaner 1309 to adjust that to deal w/ different block sizes. 1310 Also with UBC, all i/o is in terms of bytes at an offset 1311 with a certain length, so the exact block size isn't a big 1312 deal. 1313 1314 Any other wrstuden-devbsize tag may (and should) go away. 1315 1316Branch: yamt-idlelwp 1317Description: idle lwp, and some changes depending on it. 1318 1319 1. separate context switching and thread scheduling. 1320 (cf. gmcgarry_ctxsw) 1321 2. implement idle lwp. 1322 3. clean up related MD/MI interfaces. 1323 4. make scheduler(s) modular. 1324 1325Status: Terminated; merged to -current 1326Start Date: Fri Feb 17 2007 1327End Date: Thu May 17 2007 1328Base Tag: yamt-idlelwp-base8 1329Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1330Scope: src/sys (src/common is tagged but not branched) 1331Notes: 1332 Status of ports: 1333 alpha [ Done, UP tested, MP not tested ] 1334 i386 [ Done, tested ] 1335 amd64 [ Done, tested ] 1336 mips [ Done, both MIPS1 and MIPS3 tested] 1337 sparc [ Done, UP tested, MP might have 1338 some problem after newlock2 merge ] 1339 sparc64 [ Done, tested ] 1340 arm [ Done, SA1 tested.
