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: hpcarm-cleanup 305Description: Fix build problems for hpcarm 306Status: Active 307Start Date: 31 July 2007 308End Date: 309Base Tag: hpcarm-cleanup-base 310Maintainer: Robert Swindells <rjs@NetBSD.org> 311Scope: kernel 312Notes: Modify SA11x0 interrupt code to match PXA2x0 equivalent. 313 314Branch: itohy-usb1 315Description: USB stack overhaul, mostly DMA related 316Status: Active 317Start Date: 22 May 2007 318End Date: 319Base Tag: itohy-usb1-base 320Maintainer: ITOH Yasufumi <itohy@NetBSD.org> 321Scope: kernel 322Notes: To check out the kernel source tree, 323 1. check out checkout script 324 cvs checkout -ritohy-usb1 src/sys/dev/usb/filelist 325 2. update files in the branch 326 sh -e src/sys/dev/usb/filelist 327 328Branch: kame 329Description: KAME Project 330Status: Dormant 331Start Date: 28 Jun 1999 332End Date: 333Base Tag: 334Maintainer: Jun-ichiro itojun Hagino <itojun@NetBSD.org> 335Scope: kernel 336Notes: http://www.kame.net 337 Used for "reference" purposes for early part of KAME 338 integration effort.

If you plan to 456 continue this branch, sys/netinet/in_pcb.h already contains 457 the proposed structure layout (which was roughly discussed 458 in the tech-net mailing list). 459 I also defined INP_*() macros to mimicate FreeBSD's inpcb 460 locking style, but currently they do nothing and are not 461 yet called at the correct places (needs discussion about 462 kernel fine-grained locking). 463 To continue this branch, one needs to read all the relevant 464 inpcb/in6pcb source files and change the function names, 465 structure names, structure fields according to the new 466 layout (in6pcb is gone). 467 Don't try to build a kernel from this branch because it won't 468 work. The missing pieces required to do a complete build 469 were not committed because they were incomplete and generated 470 panics. 471 You shouldn't need to worry about KAME syncs because 472 they did most of them by now. 473 After the work is done, you are required to test the branch 474 (before the merge to -current) with an interop IPv6 test. 475 More info at: http://www.tahi.org/ 476 477Branch: rtr-xorg-branch 478Description: xorg & static build alterations to src/x11 479Status: Active 480Start Date: Nov 15 2004 481End Date: 482Base tag: rtr-xorg-branch-base 483Maintainer: Tyler R.

Improvements 505 include not allocating memory while preparing to tsleep(), 506 reducing inappropriate upcall delivery (hopefully also 507 eliminating the need to mlock stacks), and being 508 able to pthread_kill() running threads. At this date, 509 most goals have been achieved. This branch also includes 510 fixes to gdb to support working with threaded apps. 511 512Branch: wrstuden-revivesa 513Description: Fix a number of issues present with Scheduler Activations. 514Status: Active 515Start Date: 10 May 2008 516End Date: 517Base Tag: wrstuden-revivesa-base 518Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 519Scope: src, though all the interesting stuff is in the kernel 520Notes: This branch is intended to revive Scheduler Activations 521 in -current in the 5.0 era. This branch's main goal is 522 to re-add syscall compatability so that SA-based libpthread 523 programs can run with a -current kernel. 1:1 threading will 524 remain the NetBSD-default. This branch will re-add necessary 525 upcall support, and will also serve as a chance to clean 526 out cruft that had accumulated in the implementation over 527 time. 528 529Branch: yamt-kmem 530Description: 531 - separate kernel va allocation from kernel fault handling. 532 - make kmem_alloc interrupt-safe. 533Status: Active 534Start Date: Sun Dec 9 2007 535End Date: 536Base Tag: yamt-kmem-base3 537Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 538Scope: src/sys (src/common is tagged but not branched) 539Notes: 540 todo: 541 - investigate if PMAP_PREFER equivalent can be done 542 with vmem_xalloc. find a tester with hardware for it. 543 - g/c replaced code, including kmapent and malloc. 544 - consider to remove other submaps. eg. mb_map 545 546Branch: yamt-nfs-mp 547Description: make nfs client mp-safe 548Status: Active 549Start Date: Sun Apr 27 2008 550End Date: 551Base Tag: yamt-nfs-mp-base2 552Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 553Scope: src/sys (src/common is tagged but not branched) 554Notes: 555 556Branch: reinoud-bufcleanup 557Description: implement and evaluate struct buf usage cleanup strategies. 558 Ideas currently in mind (preference for b): 559 a) 560 1. use of bio_ops per buffer. 561 2. allow chaining/overloading of functions in bio_ops 562 and provide some private context. 563 3. extend the bio_ops with commonly used functionality 564 like pending action counting, custom context passing, 565 last minute processing of buffer data, buffer cache 566 etc. 567 4. investigate the use of the kcont() 568 continuation-passing framework for async io 569 completion notification for bufs 570 ... 571 b) 572 1. all sequencing use of B_CALL replaced by 573 device-threads, if possible generic code around BUFQ 574 2. possibly use kcont() for async IO finished signaling 575 3. counter of pending and queued actions requestable 576 by IOCTL interface? 577 4. implement `last minute buffer fixup' calls and maybe 578 even finished I/O calls as vnode operations 579 ... 580Status: Active 581Start Date: Thu Mar 15 2007 582End Date: 583Base Tag: reinoud-bufcleanup-base 584Maintainer: Reinoud Zandijk <reinoud@NetBSD.org> 585Scope: src/sys and src/common 586Notes: Used as experiment sandbox and if successful hopefully one day 587 to be integrated. 588 589Branch: simonb-wapbl 590Description: Wasabi's journaling filesystem support 591Status: Active 592Start Date: Tue Jun 10 2008 593End Date: 594Base Tag: simonb-wapbl-base 595Maintainer: Simon Burge <simonb@NetBSD.org> 596Scope: src/distrib/sets/lists/comp src/distrib/utils/sysinst 597 src/include 598 src/sbin/fsck_ffs src/sbin/fsdb src/sbin/mount_ffs 599 src/sys 600Notes: Still has a number of issues: 601 - Can't log the root filesystem (or any FS if /dev isn't an 602 ffs) or update existing mounts from non-logged to logged. 603 See kern/38057 - a fix for the PR has been committed but 604 at this stage it doesn't play well with WAPBL. 605 - Log must currently live at end of partition. 606 - No log locators. 607 - Some heavy workload performance issues on SMP machines. 608 - Some stability issues on SMP machines. 609 610Branch: thorpej-atomic 611Description: Implementation of an atomic memory operations API modeled 612 after the one in Solaris 10. 613Status: Active 614Start Date: Apr 11 2007 615End Date: 616Base tag: thorpej-atomic-base 617Maintainer: Jason Thorpe <thorpej@netbsd.org> 618Scope: src/common 619 src/sys 620Notes: Base atomic primitives need to be implemented for 621 all of the supported architectures: 622 623 alpha DONE 624 arm DONE 625 hppa 626 i386 DONE 627 ia64 628 m68k DONE (except for 68010) 629 mips 630 ns32k 631 powerpc DONE except for membar_*() 632 powerpc64 DONE except for membar_*() 633 sh3 634 sparc DONE except for membar_*() 635 sparc64 DONE except for membar_*() 636 vax 637 x86_64 DONE 638 639 Tested: 640 641 alpha NO 642 arm NO 643 hppa NO 644 i386 NO 645 ia64 NO 646 m68k NO 647 mips NO 648 ns32k NO 649 powerpc NO 650 powerpc64 NO 651 sh3 NO 652 sparc NO 653 sparc64 NO 654 vax NO 655 x86_64 NO 656 657 TODO: 658 659 all - Need to replace mb_*() with membar_*(). 660 661 - Audit MUTEX_CAS() and RWLOCK_CAS() uses 662 to see of membar_enter() is required here. 663 664 - Talk to ad@ -- figure out of non-atomic 665 mutex / rwlock release is actually safe. 666 667 arm - Consider using a RAS technique like 668 MIPS uses for _lock_cas() and the mutex 669 stubs.

In terms of UBC, the primary cache for 1280 file data is the VM cache, which needs to operate 1281 in terms of VM pages. As no existing device has native 1282 pages the same size as our VM pages, there already is 1283 a mapping going on between the VM system and the 1284 underlying blocks. So it would be easier and cleaner 1285 to adjust that to deal w/ different block sizes. 1286 Also with UBC, all i/o is in terms of bytes at an offset 1287 with a certain length, so the exact block size isn't a big 1288 deal. 1289 1290 Any other wrstuden-devbsize tag may (and should) go away. 1291 1292Branch: yamt-idlelwp 1293Description: idle lwp, and some changes depending on it. 1294 1295 1. separate context switching and thread scheduling. 1296 (cf. gmcgarry_ctxsw) 1297 2. implement idle lwp. 1298 3. clean up related MD/MI interfaces. 1299 4. make scheduler(s) modular. 1300 1301Status: Terminated; merged to -current 1302Start Date: Fri Feb 17 2007 1303End Date: Thu May 17 2007 1304Base Tag: yamt-idlelwp-base8 1305Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1306Scope: src/sys (src/common is tagged but not branched) 1307Notes: 1308 Status of ports: 1309 alpha [ Done, UP tested, MP not tested ] 1310 i386 [ Done, tested ] 1311 amd64 [ Done, tested ] 1312 mips [ Done, both MIPS1 and MIPS3 tested] 1313 sparc [ Done, UP tested, MP might have 1314 some problem after newlock2 merge ] 1315 sparc64 [ Done, tested ] 1316 arm [ Done, SA1 tested.
