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: ad-audiomp2 246Description: Add MP locking to the audio drivers 247Status: Active 248Start Date: 7 December 2008 249End Date: 250Base Tag: ad-audiomp2-base 251Maintainer: Andrew Doran <ad@NetBSD.org> 252Scope: kernel 253Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 254 255Branch: bjh21-hydra 256Description: Simtec Hydra support and ARM SMP in general 257Status: Dormant 258Start Date: 18 Oct 2002 259End Date: 260Base Tag: bjh21-hydra-base 261Maintainer: Ben Harris <bjh21@NetBSD.org> 262Scope: sys/arch/arm sys/arch/acorn32 263Notes: This code was on a branch because it involves changes to 264 cpuswitch.S which would otherwise make merging the 265 nathanw_sa branch difficult. 266 267Branch: chris-arm-intr-rework 268Description: Rework arm interrupt handling code 269Status: Active 270Start Date: 11 Aug 2007 271End Date: 272Base Tag: chris-arm-intr-rework-base 273Maintainer: Chris Gilbert <chris@NetBSD.org> 274Scope: sys/arch/arm sys/arch/cats (other arm archs to follow) 275Notes: Rework arm interrupt code to provide a shared set of interrupt 276 routines, and allow improvements to be shared across all arm 277 based hardware. 278 279Branch: cube-autoconf 280Description: Renovate autoconf(9) API 281Status: Active 282Start Date: 11 Dec 2007 283End Date: 284Base Tag: cube-autoconf-base 285Maintainer: Quentin Garnier <cube@NetBSD.org> 286Scope: kernel usr.bin/config (and some other userland bits) 287Notes: Address a number of issues the current autoconf(9) API has. 288 289Branch: gmcgarry_ctxsw 290Description: Separate scheduler from context-switch code 291Status: Dormant 292Start Date: 18 December 2002 293End Date: 294Base Tag: gmcgarry_ctxsw_base 295Maintainer: Gregory McGarry <gmcgarry@NetBSD.org> 296Scope: kernel 297Notes: Removing knowledge of the scheduler and its run queues 298 from the machine-dependent context switch code is the 299 first step in cleaning up the scheduler.

If you plan to 477 continue this branch, sys/netinet/in_pcb.h already contains 478 the proposed structure layout (which was roughly discussed 479 in the tech-net mailing list). 480 I also defined INP_*() macros to mimicate FreeBSD's inpcb 481 locking style, but currently they do nothing and are not 482 yet called at the correct places (needs discussion about 483 kernel fine-grained locking). 484 To continue this branch, one needs to read all the relevant 485 inpcb/in6pcb source files and change the function names, 486 structure names, structure fields according to the new 487 layout (in6pcb is gone). 488 Don't try to build a kernel from this branch because it won't 489 work. The missing pieces required to do a complete build 490 were not committed because they were incomplete and generated 491 panics. 492 You shouldn't need to worry about KAME syncs because 493 they did most of them by now. 494 After the work is done, you are required to test the branch 495 (before the merge to -current) with an interop IPv6 test. 496 More info at: http://www.tahi.org/ 497 498Branch: rtr-xorg-branch 499Description: xorg & static build alterations to src/x11 500Status: Active 501Start Date: Nov 15 2004 502End Date: 503Base tag: rtr-xorg-branch-base 504Maintainer: Tyler R.

Improvements 526 include not allocating memory while preparing to tsleep(), 527 reducing inappropriate upcall delivery (hopefully also 528 eliminating the need to mlock stacks), and being 529 able to pthread_kill() running threads. At this date, 530 most goals have been achieved. This branch also includes 531 fixes to gdb to support working with threaded apps. 532 533Branch: wrstuden-revivesa 534Description: Fix a number of issues present with Scheduler Activations. 535Status: Active 536Start Date: 10 May 2008 537End Date: 538Base Tag: wrstuden-revivesa-base 539Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 540Scope: src, though all the interesting stuff is in the kernel 541Notes: This branch is intended to revive Scheduler Activations 542 in -current in the 5.0 era. This branch's main goal is 543 to re-add syscall compatability so that SA-based libpthread 544 programs can run with a -current kernel. 1:1 threading will 545 remain the NetBSD-default.

In terms of UBC, the primary cache for 1314 file data is the VM cache, which needs to operate 1315 in terms of VM pages. As no existing device has native 1316 pages the same size as our VM pages, there already is 1317 a mapping going on between the VM system and the 1318 underlying blocks. So it would be easier and cleaner 1319 to adjust that to deal w/ different block sizes. 1320 Also with UBC, all i/o is in terms of bytes at an offset 1321 with a certain length, so the exact block size isn't a big 1322 deal. 1323 1324 Any other wrstuden-devbsize tag may (and should) go away. 1325 1326Branch: yamt-idlelwp 1327Description: idle lwp, and some changes depending on it. 1328 1329 1. separate context switching and thread scheduling. 1330 (cf. gmcgarry_ctxsw) 1331 2. implement idle lwp. 1332 3. clean up related MD/MI interfaces. 1333 4. make scheduler(s) modular. 1334 1335Status: Terminated; merged to -current 1336Start Date: Fri Feb 17 2007 1337End Date: Thu May 17 2007 1338Base Tag: yamt-idlelwp-base8 1339Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1340Scope: src/sys (src/common is tagged but not branched) 1341Notes: 1342 Status of ports: 1343 alpha [ Done, UP tested, MP not tested ] 1344 i386 [ Done, tested ] 1345 amd64 [ Done, tested ] 1346 mips [ Done, both MIPS1 and MIPS3 tested] 1347 sparc [ Done, UP tested, MP might have 1348 some problem after newlock2 merge ] 1349 sparc64 [ Done, tested ] 1350 arm [ Done, SA1 tested.
