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 242 drivers are converted, the remaining 1/2 need more changes. 243 244 As of import this is snapshot of work in progress and so 245 may not compile; in particular the midi changes are very 246 much "in progress". The audio component has been tested 247 and verified to work with emuxki and auvia. There may 248 be a locking issue in the ac97 code at boot. 249 250 The are two locks per device instance, an ISR lock and 251 a character device lock. The ISR lock replaces calls to 252 splaudio()/splx(), and will be held across calls to device 253 methods which were called at splaudio() before (e.g. 254 trigger_output). The character device lock is held across 255 calls to nearly all of the methods, excluding some only 256 used for initialization, e.g. get_locks. This needs to be 257 documented at merge time. 258 259 To test on a multi way x86 system, search for "mpsafe" in 260 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 261 that will acquire the ISR lock (depends on the hardware, but 262 "while true; do mixerctl -a > /dev/null; done" may suffice). 263 Play audio, run lockstat and verify that that there is 264 contention on the ISR lock. 265 266Branch: ad-audiomp2 267Description: Add MP locking to the audio drivers 268Status: Terminated 269Start Date: 7 December 2008 270End Date: 19 November 2011 271Base Tag: ad-audiomp2-base 272Maintainer: Andrew Doran <ad@NetBSD.org> 273Scope: kernel 274Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 275 276Branch: bjh21-hydra 277Description: Simtec Hydra support and ARM SMP in general 278Status: Dormant 279Start Date: 18 Oct 2002 280End Date: 281Base Tag: bjh21-hydra-base 282Maintainer: Ben Harris <bjh21@NetBSD.org> 283Scope: sys/arch/arm sys/arch/acorn32 284Notes: This code was on a branch because it involves changes to 285 cpuswitch.S which would otherwise make merging the 286 nathanw_sa branch difficult. 287 288Branch: cherry-xenmp 289Description: Port i386 and amd64 Xen kernels to run MP 290Status: Active 291Start Date: 1st June 2011 292End Date: 293Base Tag: cherry-xenmp-base 294Maintainer: Cherry G.

If you plan to 507 continue this branch, sys/netinet/in_pcb.h already contains 508 the proposed structure layout (which was roughly discussed 509 in the tech-net mailing list). 510 I also defined INP_*() macros to mimicate FreeBSD's inpcb 511 locking style, but currently they do nothing and are not 512 yet called at the correct places (needs discussion about 513 kernel fine-grained locking). 514 To continue this branch, one needs to read all the relevant 515 inpcb/in6pcb source files and change the function names, 516 structure names, structure fields according to the new 517 layout (in6pcb is gone). 518 Don't try to build a kernel from this branch because it won't 519 work. The missing pieces required to do a complete build 520 were not committed because they were incomplete and generated 521 panics. 522 You shouldn't need to worry about KAME syncs because 523 they did most of them by now. 524 After the work is done, you are required to test the branch 525 (before the merge to -current) with an interop IPv6 test. 526 More info at: http://www.tahi.org/ 527 528Branch: wrstuden-fixsa 529Description: Fix a number of issues present with Scheduler Activations. 530Status: Active 531Start Date: 15 May 2007 532End Date: 533Base Tag: wrstuden-fixsa-base 534Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 535Scope: src, though all the interesting stuff is in the kernel 536 or lib/libpthread or maybe gdb. 537Notes: This branch is based off of the netbsd-4 branch! 538 This branch is intended to stage improvements for the 539 Scheduler Activations system for NetBSD 4. Improvements 540 include not allocating memory while preparing to tsleep(), 541 reducing inappropriate upcall delivery (hopefully also 542 eliminating the need to mlock stacks), and being 543 able to pthread_kill() running threads. At this date, 544 most goals have been achieved. This branch also includes 545 fixes to gdb to support working with threaded apps. 546 547Branch: wrstuden-revivesa 548Description: Fix a number of issues present with Scheduler Activations. 549Status: Active 550Start Date: 10 May 2008 551End Date: 552Base Tag: wrstuden-revivesa-base 553Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 554Scope: src, though all the interesting stuff is in the kernel 555Notes: This branch is intended to revive Scheduler Activations 556 in -current in the 5.0 era. This branch's main goal is 557 to re-add syscall compatability so that SA-based libpthread 558 programs can run with a -current kernel. 1:1 threading will 559 remain the NetBSD-default. This branch will re-add necessary 560 upcall support, and will also serve as a chance to clean 561 out cruft that had accumulated in the implementation over 562 time. 563 564Branch: yamt-kmem 565Description: 566 - separate kernel va allocation from kernel fault handling. 567 - make kmem_alloc interrupt-safe. 568Status: Active 569Start Date: Sun Dec 9 2007 570End Date: 571Base Tag: yamt-kmem-base3 572Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 573Scope: src/sys (src/common is tagged but not branched) 574Notes: 575 todo: 576 - investigate if PMAP_PREFER equivalent can be done 577 with vmem_xalloc. find a tester with hardware for it. 578 - g/c replaced code, including kmapent and malloc. 579 - consider to remove other submaps. eg. mb_map 580 581Branch: yamt-nfs-mp 582Description: make nfs client mp-safe 583Status: Active 584Start Date: Sun Apr 27 2008 585End Date: 586Base Tag: yamt-nfs-mp-base11 587Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 588Scope: src/sys (src/common is tagged but not branched) 589Notes: 590 591Branch: yamt-pagecache 592Description: page cache related changes 593Status: Active 594Start Date: Wed Nov 2 2011 595End Date: 596Base Tag: yamt-pagecache-base3 597Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 598Scope: src 599Notes: - maintain object pages in radix tree rather than rb tree. 600 - reduce unnecessary page scan in putpages. esp. when an 601 object has a ton of pages cached but only a few of them 602 are dirty. 603 - reduce the number of pmap operations by tracking page 604 dirtiness more precisely in uvm layer. 605 - fix nfs commit range tracking. 606 - fix nfs write clustering.

In terms of UBC, the primary cache for 1383 file data is the VM cache, which needs to operate 1384 in terms of VM pages. As no existing device has native 1385 pages the same size as our VM pages, there already is 1386 a mapping going on between the VM system and the 1387 underlying blocks. So it would be easier and cleaner 1388 to adjust that to deal w/ different block sizes. 1389 Also with UBC, all i/o is in terms of bytes at an offset 1390 with a certain length, so the exact block size isn't a big 1391 deal. 1392 1393 Any other wrstuden-devbsize tag may (and should) go away. 1394 1395Branch: yamt-idlelwp 1396Description: idle lwp, and some changes depending on it. 1397 1398 1. separate context switching and thread scheduling. 1399 (cf. gmcgarry_ctxsw) 1400 2. implement idle lwp. 1401 3. clean up related MD/MI interfaces. 1402 4. make scheduler(s) modular. 1403 1404Status: Terminated; merged to -current 1405Start Date: Fri Feb 17 2007 1406End Date: Thu May 17 2007 1407Base Tag: yamt-idlelwp-base8 1408Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1409Scope: src/sys (src/common is tagged but not branched) 1410Notes: 1411 Status of ports: 1412 alpha [ Done, UP tested, MP not tested ] 1413 i386 [ Done, tested ] 1414 amd64 [ Done, tested ] 1415 mips [ Done, both MIPS1 and MIPS3 tested] 1416 sparc [ Done, UP tested, MP might have 1417 some problem after newlock2 merge ] 1418 sparc64 [ Done, tested ] 1419 arm [ Done, SA1 tested.
