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 253 drivers are converted, the remaining 1/2 need more changes. 254 255 As of import this is snapshot of work in progress and so 256 may not compile; in particular the midi changes are very 257 much "in progress". The audio component has been tested 258 and verified to work with emuxki and auvia. There may 259 be a locking issue in the ac97 code at boot. 260 261 The are two locks per device instance, an ISR lock and 262 a character device lock. The ISR lock replaces calls to 263 splaudio()/splx(), and will be held across calls to device 264 methods which were called at splaudio() before (e.g. 265 trigger_output). The character device lock is held across 266 calls to nearly all of the methods, excluding some only 267 used for initialization, e.g. get_locks. This needs to be 268 documented at merge time. 269 270 To test on a multi way x86 system, search for "mpsafe" in 271 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 272 that will acquire the ISR lock (depends on the hardware, but 273 "while true; do mixerctl -a > /dev/null; done" may suffice). 274 Play audio, run lockstat and verify that that there is 275 contention on the ISR lock. 276 277Branch: ad-audiomp2 278Description: Add MP locking to the audio drivers 279Status: Terminated 280Start Date: 7 December 2008 281End Date: 19 November 2011 282Base Tag: ad-audiomp2-base 283Maintainer: Andrew Doran <ad@NetBSD.org> 284Scope: kernel 285Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 286 287Branch: bjh21-hydra 288Description: Simtec Hydra support and ARM SMP in general 289Status: Dormant 290Start Date: 18 Oct 2002 291End Date: 292Base Tag: bjh21-hydra-base 293Maintainer: Ben Harris <bjh21@NetBSD.org> 294Scope: sys/arch/arm sys/arch/acorn32 295Notes: This code was on a branch because it involves changes to 296 cpuswitch.S which would otherwise make merging the 297 nathanw_sa branch difficult. 298 299Branch: cherry-xenmp 300Description: Port i386 and amd64 Xen kernels to run MP 301Status: Terminated 302Start Date: 1st June 2011 303End Date: 13th January 2012 304Base Tag: cherry-xenmp-base 305Maintainer: Cherry G.

If you plan to 518 continue this branch, sys/netinet/in_pcb.h already contains 519 the proposed structure layout (which was roughly discussed 520 in the tech-net mailing list). 521 I also defined INP_*() macros to mimicate FreeBSD's inpcb 522 locking style, but currently they do nothing and are not 523 yet called at the correct places (needs discussion about 524 kernel fine-grained locking). 525 To continue this branch, one needs to read all the relevant 526 inpcb/in6pcb source files and change the function names, 527 structure names, structure fields according to the new 528 layout (in6pcb is gone). 529 Don't try to build a kernel from this branch because it won't 530 work. The missing pieces required to do a complete build 531 were not committed because they were incomplete and generated 532 panics. 533 You shouldn't need to worry about KAME syncs because 534 they did most of them by now. 535 After the work is done, you are required to test the branch 536 (before the merge to -current) with an interop IPv6 test. 537 More info at: http://www.tahi.org/ 538 539Branch: wrstuden-fixsa 540Description: Fix a number of issues present with Scheduler Activations. 541Status: Active 542Start Date: 15 May 2007 543End Date: 544Base Tag: wrstuden-fixsa-base 545Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 546Scope: src, though all the interesting stuff is in the kernel 547 or lib/libpthread or maybe gdb. 548Notes: This branch is based off of the netbsd-4 branch! 549 This branch is intended to stage improvements for the 550 Scheduler Activations system for NetBSD 4. Improvements 551 include not allocating memory while preparing to tsleep(), 552 reducing inappropriate upcall delivery (hopefully also 553 eliminating the need to mlock stacks), and being 554 able to pthread_kill() running threads. At this date, 555 most goals have been achieved. This branch also includes 556 fixes to gdb to support working with threaded apps. 557 558Branch: wrstuden-revivesa 559Description: Fix a number of issues present with Scheduler Activations. 560Status: Active 561Start Date: 10 May 2008 562End Date: 563Base Tag: wrstuden-revivesa-base 564Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 565Scope: src, though all the interesting stuff is in the kernel 566Notes: This branch is intended to revive Scheduler Activations 567 in -current in the 5.0 era. This branch's main goal is 568 to re-add syscall compatability so that SA-based libpthread 569 programs can run with a -current kernel. 1:1 threading will 570 remain the NetBSD-default. This branch will re-add necessary 571 upcall support, and will also serve as a chance to clean 572 out cruft that had accumulated in the implementation over 573 time. 574 575Branch: yamt-kmem 576Description: 577 - separate kernel va allocation from kernel fault handling. 578 - make kmem_alloc interrupt-safe. 579Status: Active 580Start Date: Sun Dec 9 2007 581End Date: 582Base Tag: yamt-kmem-base3 583Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 584Scope: src/sys (src/common is tagged but not branched) 585Notes: 586 todo: 587 - investigate if PMAP_PREFER equivalent can be done 588 with vmem_xalloc. find a tester with hardware for it. 589 - g/c replaced code, including kmapent and malloc. 590 - consider to remove other submaps. eg. mb_map 591 592Branch: yamt-nfs-mp 593Description: make nfs client mp-safe 594Status: Active 595Start Date: Sun Apr 27 2008 596End Date: 597Base Tag: yamt-nfs-mp-base11 598Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 599Scope: src/sys (src/common is tagged but not branched) 600Notes: 601 602Branch: yamt-pagecache 603Description: page cache related changes 604Status: Active 605Start Date: Wed Nov 2 2011 606End Date: 607Base Tag: yamt-pagecache-base3 608Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 609Scope: src 610Notes: - maintain object pages in radix tree rather than rb tree. 611 - shrink the size of vm_page. 612 - reduce unnecessary page scan in putpages. esp. when an 613 object has a ton of pages cached but only a few of them 614 are dirty. 615 - reduce the number of pmap operations by tracking page 616 dirtiness more precisely in uvm layer. 617 - fix nfs commit range tracking. 618 - fix nfs write clustering.

In terms of UBC, the primary cache for 1475 file data is the VM cache, which needs to operate 1476 in terms of VM pages. As no existing device has native 1477 pages the same size as our VM pages, there already is 1478 a mapping going on between the VM system and the 1479 underlying blocks. So it would be easier and cleaner 1480 to adjust that to deal w/ different block sizes. 1481 Also with UBC, all i/o is in terms of bytes at an offset 1482 with a certain length, so the exact block size isn't a big 1483 deal. 1484 1485 Any other wrstuden-devbsize tag may (and should) go away. 1486 1487Branch: yamt-idlelwp 1488Description: idle lwp, and some changes depending on it. 1489 1490 1. separate context switching and thread scheduling. 1491 (cf. gmcgarry_ctxsw) 1492 2. implement idle lwp. 1493 3. clean up related MD/MI interfaces. 1494 4. make scheduler(s) modular. 1495 1496Status: Terminated; merged to -current 1497Start Date: Fri Feb 17 2007 1498End Date: Thu May 17 2007 1499Base Tag: yamt-idlelwp-base8 1500Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1501Scope: src/sys (src/common is tagged but not branched) 1502Notes: 1503 Status of ports: 1504 alpha [ Done, UP tested, MP not tested ] 1505 i386 [ Done, tested ] 1506 amd64 [ Done, tested ] 1507 mips [ Done, both MIPS1 and MIPS3 tested] 1508 sparc [ Done, UP tested, MP might have 1509 some problem after newlock2 merge ] 1510 sparc64 [ Done, tested ] 1511 arm [ Done, SA1 tested.
