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 47 Branch: comdex-fall-1999 48 Description: Special release branch for pre-1.5 release at 49 Fall 1999 COMDEX. 50 Status: Terminated 51 Start Date: 52 End Date: 53 Base Tag: comdex-fall-1999-base 54 Maintainer: mycroft 55 Scope: Entire tree. 56 Notes: 57 58 Branch: netbsd-0-9 59 Description: The NetBSD 0.9 release branch 60 Status: Terminated 61 Start Date: 62 End Date: 63 Base Tag: netbsd-0-9-base 64 Maintainer: Release Engineering <releng (a] NetBSD.org> 65 Scope: Entire tree. 66 Notes: 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 70 Branch: netbsd-1-0 71 Description: The NetBSD 1.0 release branch 72 Status: Terminated 73 Start Date: 74 End Date: 75 Base Tag: netbsd-1-0-base 76 Maintainer: Release Engineering <releng (a] NetBSD.org> 77 Scope: Entire tree. 78 Notes: 79 Commits restricted to release engineering. 80 81 Branch: netbsd-1-1 82 Description: The NetBSD 1.1 release branch 83 Status: Terminated 84 Start Date: 85 End Date: 86 Base Tag: netbsd-1-1-base 87 Maintainer: Release Engineering <releng (a] NetBSD.org> 88 Scope: Entire tree. 89 Notes: 90 Commits restricted to release engineering. 91 92 Branch: netbsd-1-2 93 Description: The NetBSD 1.2 release branch 94 Status: Terminated 95 Start Date: 96 End Date: 97 Base Tag: netbsd-1-2-base 98 Maintainer: Release Engineering <releng (a] NetBSD.org> 99 Scope: Entire tree. 100 Notes: 101 Commits restricted to release engineering. 102 103 Branch: netbsd-1-3 104 Description: The NetBSD 1.3 release branch 105 Status: Terminated 106 Start Date: 107 End Date: 108 Base Tag: netbsd-1-3-base 109 Maintainer: Release Engineering <releng (a] NetBSD.org> 110 Scope: Entire tree. 111 Notes: 112 Commits restricted to release engineering. 113 114 Branch: netbsd-1-4 115 Description: The NetBSD 1.4 release branch 116 Status: Terminated 117 Start Date: 1 Apr 2000 118 End Date: 119 Base Tag: netbsd-1-4-base 120 Maintainer: 1.4 Release Engineering <releng-1-4 (a] NetBSD.org> 121 Scope: Entire tree. 122 Notes: 123 Commits restricted to release engineering. 124 125 Branch: netbsd-1-5 126 Description: The NetBSD 1.5 release branch 127 Status: Terminated 128 Start Date: 20 Jun 2000 129 End Date: 26 Jan 2005 130 Base Tag: netbsd-1-5-base 131 Maintainer: 1.5 Release Engineering <releng-1-5 (a] NetBSD.org> 132 Scope: Entire tree. 133 Notes: 134 Commits restricted to release engineering. 135 136 Branch: netbsd-1-6 137 Description: The NetBSD 1.6 release branch 138 Status: Terminated 139 Start Date: 22 May 2002 140 End Date: 141 Base Tag: netbsd-1-6-base 142 Maintainer: 1.6 Release Engineering <releng-1-6 (a] NetBSD.org> 143 Scope: Entire tree. 144 Notes: 145 Commits restricted to Release Engineering. 146 147 Branch: netbsd-2 148 Description: The NetBSD 2 release branch 149 Status: Terminated 150 Start Date: 23 Dec 2004 151 End Date: 152 Base Tag: netbsd-2-base 153 Maintainer: 2 Release Engineering <releng-2 (a] NetBSD.org> 154 Scope: 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. 265 266 Branch: ad-audiomp2 267 Description: Add MP locking to the audio drivers 268 Status: Active 269 Start Date: 7 December 2008 270 End Date: 271 Base Tag: ad-audiomp2-base 272 Maintainer: Andrew Doran <ad (a] NetBSD.org> 273 Scope: kernel 274 Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 275 276 Branch: bjh21-hydra 277 Description: Simtec Hydra support and ARM SMP in general 278 Status: Dormant 279 Start Date: 18 Oct 2002 280 End Date: 281 Base Tag: bjh21-hydra-base 282 Maintainer: Ben Harris <bjh21 (a] NetBSD.org> 283 Scope: sys/arch/arm sys/arch/acorn32 284 Notes: 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. 287 288 Branch: cherry-xenmp 289 Description: Port i386 and amd64 Xen kernels to run MP 290 Status: Active 291 Start Date: 1st June 2011 292 End Date: 293 Base Tag: cherry-xenmp-base 294 Maintainer: Cherry G.

In addition, better 355 abstractions are provided for the whole PIC layer. The main 356 work areas are sys/arch/x86 and sys/dev/acpi. 357 358 Branch: jym-xensuspend 359 Description: Implement xm save/restore/migrate for NetBSD domU 360 Status: Active 361 Start Date: 2009-02-08 362 End Date: 363 Base Tag: jym-xensuspend-base 364 Maintainer: Jean-Yves Migeon <jym (a] NetBSD.org> 365 Scope: kernel 366 Notes: This branch contains the code required to support the Xen 367 save/restore/migrate facilities.

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/ 527 528 Branch: wrstuden-fixsa 529 Description: Fix a number of issues present with Scheduler Activations. 530 Status: Active 531 Start Date: 15 May 2007 532 End Date: 533 Base Tag: wrstuden-fixsa-base 534 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org> 535 Scope: src, though all the interesting stuff is in the kernel 536 or lib/libpthread or maybe gdb. 537 Notes: 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. 546 547 Branch: wrstuden-revivesa 548 Description: Fix a number of issues present with Scheduler Activations. 549 Status: Active 550 Start Date: 10 May 2008 551 End Date: 552 Base Tag: wrstuden-revivesa-base 553 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org> 554 Scope: src, though all the interesting stuff is in the kernel 555 Notes: 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. 563 564 Branch: yamt-kmem 565 Description: 566 - separate kernel va allocation from kernel fault handling. 567 - make kmem_alloc interrupt-safe. 568 Status: Active 569 Start Date: Sun Dec 9 2007 570 End Date: 571 Base Tag: yamt-kmem-base3 572 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 573 Scope: src/sys (src/common is tagged but not branched) 574 Notes: 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 580 581 Branch: yamt-nfs-mp 582 Description: make nfs client mp-safe 583 Status: Active 584 Start Date: Sun Apr 27 2008 585 End Date: 586 Base Tag: yamt-nfs-mp-base11 587 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 588 Scope: src/sys (src/common is tagged but not branched) 589 Notes: 590 591 Branch: reinoud-bufcleanup 592 Description: implement and evaluate struct buf usage cleanup strategies. 593 Ideas currently in mind (preference for b): 594 a) 595 1. use of bio_ops per buffer. 596 2. allow chaining/overloading of functions in bio_ops 597 and provide some private context. 598 3. extend the bio_ops with commonly used functionality 599 like pending action counting, custom context passing, 600 last minute processing of buffer data, buffer cache 601 etc. 602 4. investigate the use of the kcont() 603 continuation-passing framework for async io 604 completion notification for bufs 605 ... 606 b) 607 1. all sequencing use of B_CALL replaced by 608 device-threads, if possible generic code around BUFQ 609 2. possibly use kcont() for async IO finished signaling 610 3. counter of pending and queued actions requestable 611 by IOCTL interface?

In terms of UBC, the primary cache for 1346 file data is the VM cache, which needs to operate 1347 in terms of VM pages.

So it would be easier and cleaner 1351 to adjust that to deal w/ different block sizes. 1352 Also with UBC, all i/o is in terms of bytes at an offset 1353 with a certain length, so the exact block size isn't a big 1354 deal. 1355 1356 Any other wrstuden-devbsize tag may (and should) go away. 1357 1358 Branch: yamt-idlelwp 1359 Description: idle lwp, and some changes depending on it. 1360 1361 1. separate context switching and thread scheduling. 1362 (cf. gmcgarry_ctxsw) 1363 2. implement idle lwp. 1364 3. clean up related MD/MI interfaces. 1365 4. make scheduler(s) modular. 1366 1367 Status: Terminated; merged to -current 1368 Start Date: Fri Feb 17 2007 1369 End Date: Thu May 17 2007 1370 Base Tag: yamt-idlelwp-base8 1371 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 1372 Scope: src/sys (src/common is tagged but not branched) 1373 Notes: 1374 Status of ports: 1375 alpha [ Done, UP tested, MP not tested ] 1376 i386 [ Done, tested ] 1377 amd64 [ Done, tested ] 1378 mips [ Done, both MIPS1 and MIPS3 tested] 1379 sparc [ Done, UP tested, MP might have 1380 some problem after newlock2 merge ] 1381 sparc64 [ Done, tested ] 1382 arm [ Done, SA1 tested.
