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: Active 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: jym-xensuspend 335 Description: Implement xm save/restore/migrate for NetBSD domU 336 Status: Active 337 Start Date: 2009-02-08 338 End Date: 339 Base Tag: jym-xensuspend-base 340 Maintainer: Jean-Yves Migeon <jym (a] NetBSD.org> 341 Scope: kernel 342 Notes: This branch contains the code required to support the Xen 343 save/restore/migrate facilities.

New lock order: [vmpage-lock] -> pmap-lock. 476 Based on the patch from ad@. 477 - Simplify locking in pmap(9) modules by removing P->V locking. 478 - Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock) 479 to share locks among UVM objects where necessary. 480 - Optimize pmap_remove() with tracking in struct vm_map_entry. 481 - Unify /dev/mem et al in MI code and provide required locking. 482 483 Branch: rpaulo-netinet-merge-pcb 484 Description: merge in6pcb with inpcb 485 Status: Dormant 486 Start Date: Wed Feb 01 2006 487 End Date: 488 Base Tag: rpaulo-netinet-merge-pcb-base 489 Maintainer: Rui Paulo <rpaulo (a] NetBSD.org> 490 Scope: src/sys 491 Notes: No longer active due to the lack of time. If you plan to 492 continue this branch, sys/netinet/in_pcb.h already contains 493 the proposed structure layout (which was roughly discussed 494 in the tech-net mailing list). 495 I also defined INP_*() macros to mimicate FreeBSD's inpcb 496 locking style, but currently they do nothing and are not 497 yet called at the correct places (needs discussion about 498 kernel fine-grained locking). 499 To continue this branch, one needs to read all the relevant 500 inpcb/in6pcb source files and change the function names, 501 structure names, structure fields according to the new 502 layout (in6pcb is gone). 503 Don't try to build a kernel from this branch because it won't 504 work. The missing pieces required to do a complete build 505 were not committed because they were incomplete and generated 506 panics. 507 You shouldn't need to worry about KAME syncs because 508 they did most of them by now. 509 After the work is done, you are required to test the branch 510 (before the merge to -current) with an interop IPv6 test. 511 More info at: http://www.tahi.org/ 512 513 Branch: wrstuden-fixsa 514 Description: Fix a number of issues present with Scheduler Activations. 515 Status: Active 516 Start Date: 15 May 2007 517 End Date: 518 Base Tag: wrstuden-fixsa-base 519 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org> 520 Scope: src, though all the interesting stuff is in the kernel 521 or lib/libpthread or maybe gdb. 522 Notes: This branch is based off of the netbsd-4 branch! 523 This branch is intended to stage improvements for the 524 Scheduler Activations system for NetBSD 4. Improvements 525 include not allocating memory while preparing to tsleep(), 526 reducing inappropriate upcall delivery (hopefully also 527 eliminating the need to mlock stacks), and being 528 able to pthread_kill() running threads. At this date, 529 most goals have been achieved. This branch also includes 530 fixes to gdb to support working with threaded apps. 531 532 Branch: wrstuden-revivesa 533 Description: Fix a number of issues present with Scheduler Activations. 534 Status: Active 535 Start Date: 10 May 2008 536 End Date: 537 Base Tag: wrstuden-revivesa-base 538 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org> 539 Scope: src, though all the interesting stuff is in the kernel 540 Notes: This branch is intended to revive Scheduler Activations 541 in -current in the 5.0 era. This branch's main goal is 542 to re-add syscall compatability so that SA-based libpthread 543 programs can run with a -current kernel. 1:1 threading will 544 remain the NetBSD-default. This branch will re-add necessary 545 upcall support, and will also serve as a chance to clean 546 out cruft that had accumulated in the implementation over 547 time. 548 549 Branch: yamt-kmem 550 Description: 551 - separate kernel va allocation from kernel fault handling. 552 - make kmem_alloc interrupt-safe. 553 Status: Active 554 Start Date: Sun Dec 9 2007 555 End Date: 556 Base Tag: yamt-kmem-base3 557 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 558 Scope: src/sys (src/common is tagged but not branched) 559 Notes: 560 todo: 561 - investigate if PMAP_PREFER equivalent can be done 562 with vmem_xalloc. find a tester with hardware for it. 563 - g/c replaced code, including kmapent and malloc. 564 - consider to remove other submaps. eg. mb_map 565 566 Branch: yamt-nfs-mp 567 Description: make nfs client mp-safe 568 Status: Active 569 Start Date: Sun Apr 27 2008 570 End Date: 571 Base Tag: yamt-nfs-mp-base11 572 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 573 Scope: src/sys (src/common is tagged but not branched) 574 Notes: 575 576 Branch: reinoud-bufcleanup 577 Description: implement and evaluate struct buf usage cleanup strategies. 578 Ideas currently in mind (preference for b): 579 a) 580 1. use of bio_ops per buffer. 581 2. allow chaining/overloading of functions in bio_ops 582 and provide some private context. 583 3. extend the bio_ops with commonly used functionality 584 like pending action counting, custom context passing, 585 last minute processing of buffer data, buffer cache 586 etc. 587 4. investigate the use of the kcont() 588 continuation-passing framework for async io 589 completion notification for bufs 590 ... 591 b) 592 1. all sequencing use of B_CALL replaced by 593 device-threads, if possible generic code around BUFQ 594 2. possibly use kcont() for async IO finished signaling 595 3. counter of pending and queued actions requestable 596 by IOCTL interface?

In terms of UBC, the primary cache for 1298 file data is the VM cache, which needs to operate 1299 in terms of VM pages. As no existing device has native 1300 pages the same size as our VM pages, there already is 1301 a mapping going on between the VM system and the 1302 underlying blocks. So it would be easier and cleaner 1303 to adjust that to deal w/ different block sizes. 1304 Also with UBC, all i/o is in terms of bytes at an offset 1305 with a certain length, so the exact block size isn't a big 1306 deal. 1307 1308 Any other wrstuden-devbsize tag may (and should) go away. 1309 1310 Branch: yamt-idlelwp 1311 Description: idle lwp, and some changes depending on it. 1312 1313 1. separate context switching and thread scheduling. 1314 (cf. gmcgarry_ctxsw) 1315 2. implement idle lwp. 1316 3. clean up related MD/MI interfaces. 1317 4. make scheduler(s) modular. 1318 1319 Status: Terminated; merged to -current 1320 Start Date: Fri Feb 17 2007 1321 End Date: Thu May 17 2007 1322 Base Tag: yamt-idlelwp-base8 1323 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 1324 Scope: src/sys (src/common is tagged but not branched) 1325 Notes: 1326 Status of ports: 1327 alpha [ Done, UP tested, MP not tested ] 1328 i386 [ Done, tested ] 1329 amd64 [ Done, tested ] 1330 mips [ Done, both MIPS1 and MIPS3 tested] 1331 sparc [ Done, UP tested, MP might have 1332 some problem after newlock2 merge ] 1333 sparc64 [ Done, tested ] 1334 arm [ Done, SA1 tested.
