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: chris-arm-intr-rework 289 Description: Rework arm interrupt handling code 290 Status: Dormant 291 Start Date: 11 Aug 2007 292 End Date: 293 Base Tag: chris-arm-intr-rework-base 294 Maintainer: Chris Gilbert <chris (a] NetBSD.org> 295 Scope: sys/arch/arm sys/arch/cats (other arm archs to follow) 296 Notes: Rework arm interrupt code to provide a shared set of interrupt 297 routines, and allow improvements to be shared across all arm 298 based hardware. 299 300 Branch: gmcgarry_ucred 301 Description: Integrate and encapsulate user credentials 302 Status: Dormant 303 Start Date: 18 December 2002 304 End Date: 305 Base Tag: gmcgarry_ucred_base 306 Maintainer: Gregory McGarry <gmcgarry (a] NetBSD.org> 307 Scope: kernel 308 Notes: merge pcred and ucred and poolify 309 310 Branch: hpcarm-cleanup 311 Description: Fix build problems for hpcarm 312 Status: Active 313 Start Date: 31 July 2007 314 End Date: 315 Base Tag: hpcarm-cleanup-base 316 Maintainer: Robert Swindells <rjs (a] NetBSD.org> 317 Scope: kernel 318 Notes: Modify SA11x0 interrupt code to match PXA2x0 equivalent. 319 320 Branch: itohy-usb1 321 Description: USB stack overhaul, mostly DMA related 322 Status: Terminated 323 Start Date: 22 May 2007 324 End Date: 325 Base Tag: itohy-usb1-base 326 Maintainer: ITOH Yasufumi <itohy (a] NetBSD.org> 327 Scope: kernel 328 Notes: To check out the kernel source tree, 329 1. check out checkout script 330 cvs checkout -ritohy-usb1 src/sys/dev/usb/filelist 331 2. update files in the branch 332 sh -e src/sys/dev/usb/filelist 333 334 Branch: jruoho-x86intr 335 Description: Cleanup and rework the x86 APIC and PIC subsystems 336 Status: Active 337 Start Date: 17 January 2011 338 End Date: 339 Base Tag: jruoho-x86intr-base 340 Maintainer: Jukka Ruohonen <jruoho (a] NetBSD.org> 341 Scope: kernel 342 Notes: This branch aims to cleanup the x86 interrupt routing code. 343 In particular, a new implementation is provided for all 344 elements of the APIC that involve ACPI. In addition, better 345 abstractions are provided for the whole PIC layer. The main 346 work areas are sys/arch/x86 and sys/dev/acpi. 347 348 Branch: jym-xensuspend 349 Description: Implement xm save/restore/migrate for NetBSD domU 350 Status: Active 351 Start Date: 2009-02-08 352 End Date: 353 Base Tag: jym-xensuspend-base 354 Maintainer: Jean-Yves Migeon <jym (a] NetBSD.org> 355 Scope: kernel 356 Notes: This branch contains the code required to support the Xen 357 save/restore/migrate facilities. It affects domU frontend 358 drivers (xbd, xennet, xencons, hypervisor), autoconf(9) 359 machinery, as well as MD code (mostly pmap(9)). 360 361 Branch: kame 362 Description: KAME Project 363 Status: Dormant 364 Start Date: 28 Jun 1999 365 End Date: 366 Base Tag: 367 Maintainer: Jun-ichiro itojun Hagino <itojun (a] NetBSD.org> 368 Scope: kernel 369 Notes: http://www.kame.net 370 Used for "reference" purposes for early part of KAME 371 integration effort.

New lock order: [vmpage-lock] -> pmap-lock. 500 Based on the patch from ad@. 501 - Simplify locking in pmap(9) modules by removing P->V locking. 502 - Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock) 503 to share locks among UVM objects where necessary. 504 - Rewrite and optimize x86 TLB shootdown code. 505 - Unify /dev/mem et al in MI code and provide required locking. 506 507 Future work: 508 509 - Optimize pmap_remove() with tracking in struct vm_map_entry. 510 511 Branch: rpaulo-netinet-merge-pcb 512 Description: merge in6pcb with inpcb 513 Status: Dormant 514 Start Date: Wed Feb 01 2006 515 End Date: 516 Base Tag: rpaulo-netinet-merge-pcb-base 517 Maintainer: Rui Paulo <rpaulo (a] NetBSD.org> 518 Scope: src/sys 519 Notes: No longer active due to the lack of time. If you plan to 520 continue this branch, sys/netinet/in_pcb.h already contains 521 the proposed structure layout (which was roughly discussed 522 in the tech-net mailing list). 523 I also defined INP_*() macros to mimicate FreeBSD's inpcb 524 locking style, but currently they do nothing and are not 525 yet called at the correct places (needs discussion about 526 kernel fine-grained locking). 527 To continue this branch, one needs to read all the relevant 528 inpcb/in6pcb source files and change the function names, 529 structure names, structure fields according to the new 530 layout (in6pcb is gone). 531 Don't try to build a kernel from this branch because it won't 532 work. The missing pieces required to do a complete build 533 were not committed because they were incomplete and generated 534 panics. 535 You shouldn't need to worry about KAME syncs because 536 they did most of them by now. 537 After the work is done, you are required to test the branch 538 (before the merge to -current) with an interop IPv6 test. 539 More info at: http://www.tahi.org/ 540 541 Branch: wrstuden-fixsa 542 Description: Fix a number of issues present with Scheduler Activations. 543 Status: Active 544 Start Date: 15 May 2007 545 End Date: 546 Base Tag: wrstuden-fixsa-base 547 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org> 548 Scope: src, though all the interesting stuff is in the kernel 549 or lib/libpthread or maybe gdb. 550 Notes: This branch is based off of the netbsd-4 branch! 551 This branch is intended to stage improvements for the 552 Scheduler Activations system for NetBSD 4. Improvements 553 include not allocating memory while preparing to tsleep(), 554 reducing inappropriate upcall delivery (hopefully also 555 eliminating the need to mlock stacks), and being 556 able to pthread_kill() running threads. At this date, 557 most goals have been achieved. This branch also includes 558 fixes to gdb to support working with threaded apps. 559 560 Branch: wrstuden-revivesa 561 Description: Fix a number of issues present with Scheduler Activations. 562 Status: Active 563 Start Date: 10 May 2008 564 End Date: 565 Base Tag: wrstuden-revivesa-base 566 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org> 567 Scope: src, though all the interesting stuff is in the kernel 568 Notes: This branch is intended to revive Scheduler Activations 569 in -current in the 5.0 era. This branch's main goal is 570 to re-add syscall compatability so that SA-based libpthread 571 programs can run with a -current kernel. 1:1 threading will 572 remain the NetBSD-default. This branch will re-add necessary 573 upcall support, and will also serve as a chance to clean 574 out cruft that had accumulated in the implementation over 575 time. 576 577 Branch: yamt-kmem 578 Description: 579 - separate kernel va allocation from kernel fault handling. 580 - make kmem_alloc interrupt-safe. 581 Status: Active 582 Start Date: Sun Dec 9 2007 583 End Date: 584 Base Tag: yamt-kmem-base3 585 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 586 Scope: src/sys (src/common is tagged but not branched) 587 Notes: 588 todo: 589 - investigate if PMAP_PREFER equivalent can be done 590 with vmem_xalloc. find a tester with hardware for it. 591 - g/c replaced code, including kmapent and malloc. 592 - consider to remove other submaps. eg. mb_map 593 594 Branch: yamt-nfs-mp 595 Description: make nfs client mp-safe 596 Status: Active 597 Start Date: Sun Apr 27 2008 598 End Date: 599 Base Tag: yamt-nfs-mp-base11 600 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 601 Scope: src/sys (src/common is tagged but not branched) 602 Notes: 603 604 Branch: reinoud-bufcleanup 605 Description: implement and evaluate struct buf usage cleanup strategies. 606 Ideas currently in mind (preference for b): 607 a) 608 1. use of bio_ops per buffer. 609 2. allow chaining/overloading of functions in bio_ops 610 and provide some private context. 611 3. extend the bio_ops with commonly used functionality 612 like pending action counting, custom context passing, 613 last minute processing of buffer data, buffer cache 614 etc. 615 4. investigate the use of the kcont() 616 continuation-passing framework for async io 617 completion notification for bufs 618 ... 619 b) 620 1. all sequencing use of B_CALL replaced by 621 device-threads, if possible generic code around BUFQ 622 2. possibly use kcont() for async IO finished signaling 623 3. counter of pending and queued actions requestable 624 by IOCTL interface?

In terms of UBC, the primary cache for 1336 file data is the VM cache, which needs to operate 1337 in terms of VM pages. As no existing device has native 1338 pages the same size as our VM pages, there already is 1339 a mapping going on between the VM system and the 1340 underlying blocks. So it would be easier and cleaner 1341 to adjust that to deal w/ different block sizes. 1342 Also with UBC, all i/o is in terms of bytes at an offset 1343 with a certain length, so the exact block size isn't a big 1344 deal. 1345 1346 Any other wrstuden-devbsize tag may (and should) go away. 1347 1348 Branch: yamt-idlelwp 1349 Description: idle lwp, and some changes depending on it. 1350 1351 1. separate context switching and thread scheduling. 1352 (cf. gmcgarry_ctxsw) 1353 2. implement idle lwp. 1354 3. clean up related MD/MI interfaces. 1355 4. make scheduler(s) modular. 1356 1357 Status: Terminated; merged to -current 1358 Start Date: Fri Feb 17 2007 1359 End Date: Thu May 17 2007 1360 Base Tag: yamt-idlelwp-base8 1361 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 1362 Scope: src/sys (src/common is tagged but not branched) 1363 Notes: 1364 Status of ports: 1365 alpha [ Done, UP tested, MP not tested ] 1366 i386 [ Done, tested ] 1367 amd64 [ Done, tested ] 1368 mips [ Done, both MIPS1 and MIPS3 tested] 1369 sparc [ Done, UP tested, MP might have 1370 some problem after newlock2 merge ] 1371 sparc64 [ Done, tested ] 1372 arm [ Done, SA1 tested.
