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: agc-netpgp-standalone 288Description: Remove dependency on openssl libraries in netpgp 289Status: Active 290Start Date: 5 May 2012 291End Date: 292Base Tag: agc-netpgp-standalone-base 293Maintainer: Alistair Crooks <agc@NetBSD.org> 294Scope: src/crypto/external/bsd/netpgp 295Notes: This branch is used to develop the version of netpgp 296 which has its own version of bignum, ciphers, and signatures 297 libraries, so that it is able to operate without openssl 298 being in place. 299 300Branch: agc-symver 301Description: Add library symbol versioning information 302Status: Active 303Start Date: 24 March 2013 304End Date: 305Base Tag: agc-symver-base 306Maintainer: Alistair Crooks <agc@NetBSD.org> 307Scope: src 308Notes: This branch is used to develop DSO symbol versioning, allowing 309 symbols to be added, modified and removed from shared libraries. 310 311Branch: bjh21-hydra 312Description: Simtec Hydra support and ARM SMP in general 313Status: Dormant 314Start Date: 18 Oct 2002 315End Date: 316Base Tag: bjh21-hydra-base 317Maintainer: Ben Harris <bjh21@NetBSD.org> 318Scope: sys/arch/arm sys/arch/acorn32 319Notes: This code was on a branch because it involves changes to 320 cpuswitch.S which would otherwise make merging the 321 nathanw_sa branch difficult. 322 323Branch: cherry-xenmp 324Description: Port i386 and amd64 Xen kernels to run MP 325Status: Terminated 326Start Date: 1st June 2011 327End Date: 13th January 2012 328Base Tag: cherry-xenmp-base 329Maintainer: Cherry G.

If you plan to 542 continue this branch, sys/netinet/in_pcb.h already contains 543 the proposed structure layout (which was roughly discussed 544 in the tech-net mailing list). 545 I also defined INP_*() macros to mimicate FreeBSD's inpcb 546 locking style, but currently they do nothing and are not 547 yet called at the correct places (needs discussion about 548 kernel fine-grained locking). 549 To continue this branch, one needs to read all the relevant 550 inpcb/in6pcb source files and change the function names, 551 structure names, structure fields according to the new 552 layout (in6pcb is gone). 553 Don't try to build a kernel from this branch because it won't 554 work. The missing pieces required to do a complete build 555 were not committed because they were incomplete and generated 556 panics. 557 You shouldn't need to worry about KAME syncs because 558 they did most of them by now. 559 After the work is done, you are required to test the branch 560 (before the merge to -current) with an interop IPv6 test. 561 More info at: http://www.tahi.org/ 562 563Branch: wrstuden-fixsa 564Description: Fix a number of issues present with Scheduler Activations. 565Status: Active 566Start Date: 15 May 2007 567End Date: 568Base Tag: wrstuden-fixsa-base 569Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 570Scope: src, though all the interesting stuff is in the kernel 571 or lib/libpthread or maybe gdb. 572Notes: This branch is based off of the netbsd-4 branch! 573 This branch is intended to stage improvements for the 574 Scheduler Activations system for NetBSD 4. Improvements 575 include not allocating memory while preparing to tsleep(), 576 reducing inappropriate upcall delivery (hopefully also 577 eliminating the need to mlock stacks), and being 578 able to pthread_kill() running threads. At this date, 579 most goals have been achieved. This branch also includes 580 fixes to gdb to support working with threaded apps. 581 582Branch: wrstuden-revivesa 583Description: Fix a number of issues present with Scheduler Activations. 584Status: Active 585Start Date: 10 May 2008 586End Date: 587Base Tag: wrstuden-revivesa-base 588Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 589Scope: src, though all the interesting stuff is in the kernel 590Notes: This branch is intended to revive Scheduler Activations 591 in -current in the 5.0 era. This branch's main goal is 592 to re-add syscall compatability so that SA-based libpthread 593 programs can run with a -current kernel. 1:1 threading will 594 remain the NetBSD-default. This branch will re-add necessary 595 upcall support, and will also serve as a chance to clean 596 out cruft that had accumulated in the implementation over 597 time. 598 599Branch: yamt-kmem 600Description: 601 - separate kernel va allocation from kernel fault handling. 602 - make kmem_alloc interrupt-safe. 603Status: Active 604Start Date: Sun Dec 9 2007 605End Date: 606Base Tag: yamt-kmem-base3 607Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 608Scope: src/sys (src/common is tagged but not branched) 609Notes: 610 todo: 611 - investigate if PMAP_PREFER equivalent can be done 612 with vmem_xalloc. find a tester with hardware for it. 613 - g/c replaced code, including kmapent and malloc. 614 - consider to remove other submaps. eg. mb_map 615 616Branch: yamt-nfs-mp 617Description: make nfs client mp-safe 618Status: Active 619Start Date: Sun Apr 27 2008 620End Date: 621Base Tag: yamt-nfs-mp-base11 622Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 623Scope: src/sys (src/common is tagged but not branched) 624Notes: 625 626Branch: yamt-pagecache 627Description: page cache related changes 628Status: Active 629Start Date: Wed Nov 2 2011 630End Date: 631Base Tag: yamt-pagecache-base8 632Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 633Scope: src 634Notes: - maintain object pages in radix tree rather than rb tree. 635 - shrink the size of vm_page. 636 - reduce unnecessary page scan in putpages. esp. when an 637 object has a ton of pages cached but only a few of them 638 are dirty. 639 - reduce the number of pmap operations by tracking page 640 dirtiness more precisely in uvm layer. 641 - fix nfs commit range tracking. 642 - fix nfs write clustering.

In terms of UBC, the primary cache for 1502 file data is the VM cache, which needs to operate 1503 in terms of VM pages. As no existing device has native 1504 pages the same size as our VM pages, there already is 1505 a mapping going on between the VM system and the 1506 underlying blocks. So it would be easier and cleaner 1507 to adjust that to deal w/ different block sizes. 1508 Also with UBC, all i/o is in terms of bytes at an offset 1509 with a certain length, so the exact block size isn't a big 1510 deal. 1511 1512 Any other wrstuden-devbsize tag may (and should) go away. 1513 1514Branch: yamt-idlelwp 1515Description: idle lwp, and some changes depending on it. 1516 1517 1. separate context switching and thread scheduling. 1518 (cf. gmcgarry_ctxsw) 1519 2. implement idle lwp. 1520 3. clean up related MD/MI interfaces. 1521 4. make scheduler(s) modular. 1522 1523Status: Terminated; merged to -current 1524Start Date: Fri Feb 17 2007 1525End Date: Thu May 17 2007 1526Base Tag: yamt-idlelwp-base8 1527Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1528Scope: src/sys (src/common is tagged but not branched) 1529Notes: 1530 Status of ports: 1531 alpha [ Done, UP tested, MP not tested ] 1532 i386 [ Done, tested ] 1533 amd64 [ Done, tested ] 1534 mips [ Done, both MIPS1 and MIPS3 tested] 1535 sparc [ Done, UP tested, MP might have 1536 some problem after newlock2 merge ] 1537 sparc64 [ Done, tested ] 1538 arm [ Done, SA1 tested.
