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: haad-dm 305Description: Add support for LVM to NetBSD 306Status: Active 307Start Date: 7 July 2008 308End Date: 309Base Tag: haad-dm-base 310Maintainer: Adam Hamsik <haad@NetBSD.org> 311Scope: kernel 312Notes: LVM support is based on Linux lvm2tools, 313 libdevmapper library and NetBSD device-mapper 314 driver. 315 316Branch: hpcarm-cleanup 317Description: Fix build problems for hpcarm 318Status: Active 319Start Date: 31 July 2007 320End Date: 321Base Tag: hpcarm-cleanup-base 322Maintainer: Robert Swindells <rjs@NetBSD.org> 323Scope: kernel 324Notes: Modify SA11x0 interrupt code to match PXA2x0 equivalent. 325 326Branch: itohy-usb1 327Description: USB stack overhaul, mostly DMA related 328Status: Active 329Start Date: 22 May 2007 330End Date: 331Base Tag: itohy-usb1-base 332Maintainer: ITOH Yasufumi <itohy@NetBSD.org> 333Scope: kernel 334Notes: To check out the kernel source tree, 335 1. check out checkout script 336 cvs checkout -ritohy-usb1 src/sys/dev/usb/filelist 337 2. update files in the branch 338 sh -e src/sys/dev/usb/filelist 339 340Branch: kame 341Description: KAME Project 342Status: Dormant 343Start Date: 28 Jun 1999 344End Date: 345Base Tag: 346Maintainer: Jun-ichiro itojun Hagino <itojun@NetBSD.org> 347Scope: kernel 348Notes: http://www.kame.net 349 Used for "reference" purposes for early part of KAME 350 integration effort.

If you plan to 468 continue this branch, sys/netinet/in_pcb.h already contains 469 the proposed structure layout (which was roughly discussed 470 in the tech-net mailing list). 471 I also defined INP_*() macros to mimicate FreeBSD's inpcb 472 locking style, but currently they do nothing and are not 473 yet called at the correct places (needs discussion about 474 kernel fine-grained locking). 475 To continue this branch, one needs to read all the relevant 476 inpcb/in6pcb source files and change the function names, 477 structure names, structure fields according to the new 478 layout (in6pcb is gone). 479 Don't try to build a kernel from this branch because it won't 480 work. The missing pieces required to do a complete build 481 were not committed because they were incomplete and generated 482 panics. 483 You shouldn't need to worry about KAME syncs because 484 they did most of them by now. 485 After the work is done, you are required to test the branch 486 (before the merge to -current) with an interop IPv6 test. 487 More info at: http://www.tahi.org/ 488 489Branch: rtr-xorg-branch 490Description: xorg & static build alterations to src/x11 491Status: Active 492Start Date: Nov 15 2004 493End Date: 494Base tag: rtr-xorg-branch-base 495Maintainer: Tyler R.

Improvements 517 include not allocating memory while preparing to tsleep(), 518 reducing inappropriate upcall delivery (hopefully also 519 eliminating the need to mlock stacks), and being 520 able to pthread_kill() running threads. At this date, 521 most goals have been achieved. This branch also includes 522 fixes to gdb to support working with threaded apps. 523 524Branch: wrstuden-revivesa 525Description: Fix a number of issues present with Scheduler Activations. 526Status: Active 527Start Date: 10 May 2008 528End Date: 529Base Tag: wrstuden-revivesa-base 530Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org> 531Scope: src, though all the interesting stuff is in the kernel 532Notes: This branch is intended to revive Scheduler Activations 533 in -current in the 5.0 era. This branch's main goal is 534 to re-add syscall compatability so that SA-based libpthread 535 programs can run with a -current kernel. 1:1 threading will 536 remain the NetBSD-default. This branch will re-add necessary 537 upcall support, and will also serve as a chance to clean 538 out cruft that had accumulated in the implementation over 539 time. 540 541Branch: yamt-kmem 542Description: 543 - separate kernel va allocation from kernel fault handling. 544 - make kmem_alloc interrupt-safe. 545Status: Active 546Start Date: Sun Dec 9 2007 547End Date: 548Base Tag: yamt-kmem-base3 549Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 550Scope: src/sys (src/common is tagged but not branched) 551Notes: 552 todo: 553 - investigate if PMAP_PREFER equivalent can be done 554 with vmem_xalloc. find a tester with hardware for it. 555 - g/c replaced code, including kmapent and malloc. 556 - consider to remove other submaps. eg. mb_map 557 558Branch: yamt-nfs-mp 559Description: make nfs client mp-safe 560Status: Active 561Start Date: Sun Apr 27 2008 562End Date: 563Base Tag: yamt-nfs-mp-base2 564Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 565Scope: src/sys (src/common is tagged but not branched) 566Notes: 567 568Branch: reinoud-bufcleanup 569Description: implement and evaluate struct buf usage cleanup strategies. 570 Ideas currently in mind (preference for b): 571 a) 572 1. use of bio_ops per buffer. 573 2. allow chaining/overloading of functions in bio_ops 574 and provide some private context. 575 3. extend the bio_ops with commonly used functionality 576 like pending action counting, custom context passing, 577 last minute processing of buffer data, buffer cache 578 etc. 579 4. investigate the use of the kcont() 580 continuation-passing framework for async io 581 completion notification for bufs 582 ... 583 b) 584 1. all sequencing use of B_CALL replaced by 585 device-threads, if possible generic code around BUFQ 586 2. possibly use kcont() for async IO finished signaling 587 3. counter of pending and queued actions requestable 588 by IOCTL interface? 589 4. implement `last minute buffer fixup' calls and maybe 590 even finished I/O calls as vnode operations 591 ... 592Status: Active 593Start Date: Thu Mar 15 2007 594End Date: 595Base Tag: reinoud-bufcleanup-base 596Maintainer: Reinoud Zandijk <reinoud@NetBSD.org> 597Scope: src/sys and src/common 598Notes: Used as experiment sandbox and if successful hopefully one day 599 to be integrated. 600 601Branch: simonb-wapbl 602Description: Wasabi's journaling filesystem support 603Status: Active 604Start Date: Tue Jun 10 2008 605End Date: 606Base Tag: simonb-wapbl-base 607Maintainer: Simon Burge <simonb@NetBSD.org> 608Scope: src/distrib/sets/lists/comp src/distrib/utils/sysinst 609 src/include 610 src/sbin/fsck_ffs src/sbin/fsdb src/sbin/mount_ffs 611 src/sys 612Notes: Still has a number of issues: 613 - Can't log the root filesystem (or any FS if /dev isn't an 614 ffs) or update existing mounts from non-logged to logged. 615 See kern/38057 - a fix for the PR has been committed but 616 at this stage it doesn't play well with WAPBL. 617 - Log must currently live at end of partition. 618 - No log locators. 619 - Some heavy workload performance issues on SMP machines. 620 - Removing large files (sparse only?) takes a long time. 621 Eg, a file created with 622 dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550 623 takes 0:00.00 to remove on my test box without logging and 624 0:22.25 to remove with logging.

In terms of UBC, the primary cache for 1296 file data is the VM cache, which needs to operate 1297 in terms of VM pages. As no existing device has native 1298 pages the same size as our VM pages, there already is 1299 a mapping going on between the VM system and the 1300 underlying blocks. So it would be easier and cleaner 1301 to adjust that to deal w/ different block sizes. 1302 Also with UBC, all i/o is in terms of bytes at an offset 1303 with a certain length, so the exact block size isn't a big 1304 deal. 1305 1306 Any other wrstuden-devbsize tag may (and should) go away. 1307 1308Branch: yamt-idlelwp 1309Description: idle lwp, and some changes depending on it. 1310 1311 1. separate context switching and thread scheduling. 1312 (cf. gmcgarry_ctxsw) 1313 2. implement idle lwp. 1314 3. clean up related MD/MI interfaces. 1315 4. make scheduler(s) modular. 1316 1317Status: Terminated; merged to -current 1318Start Date: Fri Feb 17 2007 1319End Date: Thu May 17 2007 1320Base Tag: yamt-idlelwp-base8 1321Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1322Scope: src/sys (src/common is tagged but not branched) 1323Notes: 1324 Status of ports: 1325 alpha [ Done, UP tested, MP not tested ] 1326 i386 [ Done, tested ] 1327 amd64 [ Done, tested ] 1328 mips [ Done, both MIPS1 and MIPS3 tested] 1329 sparc [ Done, UP tested, MP might have 1330 some problem after newlock2 merge ] 1331 sparc64 [ Done, tested ] 1332 arm [ Done, SA1 tested.
