1 # $NetBSD: BRANCHES,v 1.275 2009/01/11 14:49:48 christos Exp $ 2 # 3 # This file contains a list of branches that exist in the NetBSD CVS 4 # tree and their current state. 5 # 6 # This list is necessarily incomplete. 7 # 8 # Within reason, developers may create branch and version tags at any 9 # time for any purpose. 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: ? 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 232 drivers are converted, the remaining 1/2 need more changes. 233 234 As of import this is snapshot of work in progress and so 235 may not compile; in particular the midi changes are very 236 much "in progress". The audio component has been tested 237 and verified to work with emuxki and auvia. There may 238 be a locking issue in the ac97 code at boot. 239 240 The are two locks per device instance, an ISR lock and 241 a character device lock. The ISR lock replaces calls to 242 splaudio()/splx(), and will be held across calls to device 243 methods which were called at splaudio() before (e.g. 244 trigger_output). The character device lock is held across 245 calls to nearly all of the methods, excluding some only 246 used for initialization, e.g. get_locks. This needs to be 247 documented at merge time. 248 249 To test on a multi way x86 system, search for "mpsafe" in 250 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 251 that will acquire the ISR lock (depends on the hardware, but 252 "while true; do mixerctl -a > /dev/null; done" may suffice). 253 Play audio, run lockstat and verify that that there is 254 contention on the ISR lock. 255 256 Branch: ad-audiomp2 257 Description: Add MP locking to the audio drivers 258 Status: Active 259 Start Date: 7 December 2008 260 End Date: 261 Base Tag: ad-audiomp2-base 262 Maintainer: Andrew Doran <ad (a] NetBSD.org> 263 Scope: kernel 264 Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 265 266 Branch: bjh21-hydra 267 Description: Simtec Hydra support and ARM SMP in general 268 Status: Dormant 269 Start Date: 18 Oct 2002 270 End Date: 271 Base Tag: bjh21-hydra-base 272 Maintainer: Ben Harris <bjh21 (a] NetBSD.org> 273 Scope: sys/arch/arm sys/arch/acorn32 274 Notes: This code was on a branch because it involves changes to 275 cpuswitch.S which would otherwise make merging the 276 nathanw_sa branch difficult. 277 278 Branch: chris-arm-intr-rework 279 Description: Rework arm interrupt handling code 280 Status: Active 281 Start Date: 11 Aug 2007 282 End Date: 283 Base Tag: chris-arm-intr-rework-base 284 Maintainer: Chris Gilbert <chris (a] NetBSD.org> 285 Scope: sys/arch/arm sys/arch/cats (other arm archs to follow) 286 Notes: Rework arm interrupt code to provide a shared set of interrupt 287 routines, and allow improvements to be shared across all arm 288 based hardware. 289 290 Branch: cube-autoconf 291 Description: Renovate autoconf(9) API 292 Status: Active 293 Start Date: 11 Dec 2007 294 End Date: 295 Base Tag: cube-autoconf-base 296 Maintainer: Quentin Garnier <cube (a] NetBSD.org> 297 Scope: kernel usr.bin/config (and some other userland bits) 298 Notes: Address a number of issues the current autoconf(9) API has. 299 300 Branch: gmcgarry_ctxsw 301 Description: Separate scheduler from context-switch code 302 Status: Dormant 303 Start Date: 18 December 2002 304 End Date: 305 Base Tag: gmcgarry_ctxsw_base 306 Maintainer: Gregory McGarry <gmcgarry (a] NetBSD.org> 307 Scope: kernel 308 Notes: Removing knowledge of the scheduler and its run queues 309 from the machine-dependent context switch code is the 310 first step in cleaning up the scheduler. It is necessary 311 for the newlock branch, making the scheduler SMP friendly, 312 adding real-time scheduler extensions, and reducing the 313 number of code paths for LWP and proc switching. 314 315 Branch: gmcgarry_ucred 316 Description: Integrate and encapsulate user credentials 317 Status: Dormant 318 Start Date: 18 December 2002 319 End Date: 320 Base Tag: gmcgarry_ucred_base 321 Maintainer: Gregory McGarry <gmcgarry (a] NetBSD.org> 322 Scope: kernel 323 Notes: merge pcred and ucred and poolify 324 325 Branch: hpcarm-cleanup 326 Description: Fix build problems for hpcarm 327 Status: Active 328 Start Date: 31 July 2007 329 End Date: 330 Base Tag: hpcarm-cleanup-base 331 Maintainer: Robert Swindells <rjs (a] NetBSD.org> 332 Scope: kernel 333 Notes: Modify SA11x0 interrupt code to match PXA2x0 equivalent. 334 335 Branch: itohy-usb1 336 Description: USB stack overhaul, mostly DMA related 337 Status: Active 338 Start Date: 22 May 2007 339 End Date: 340 Base Tag: itohy-usb1-base 341 Maintainer: ITOH Yasufumi <itohy (a] NetBSD.org> 342 Scope: kernel 343 Notes: To check out the kernel source tree, 344 1. check out checkout script 345 cvs checkout -ritohy-usb1 src/sys/dev/usb/filelist 346 2. update files in the branch 347 sh -e src/sys/dev/usb/filelist 348 349 Branch: kame 350 Description: KAME Project 351 Status: Dormant 352 Start Date: 28 Jun 1999 353 End Date: 354 Base Tag: 355 Maintainer: Jun-ichiro itojun Hagino <itojun (a] NetBSD.org> 356 Scope: kernel 357 Notes: http://www.kame.net 358 Used for "reference" purposes for early part of KAME 359 integration effort.

The branch is 452 currently only the kernel, but will likely extend to some userland 453 areas. 454 455 Branch: pkgviews 456 Description: package views, enabling multiple conflicting packages to co-exist 457 Status: Active 458 Start Date: 22 July 2002 459 End Date: 460 Base Tag: pkgviews 461 Maintainer: Alistair Crooks <agc (a] NetBSD.org> 462 Scope: pkgsrc, basesrc/usr.sbin/pkg_install 463 Notes: A more flexible infrastructure for third-party packages by 464 allowing multiple conflicting packages and versions to co-exist 465 within the same tree 466 467 Branch: rpaulo-netinet-merge-pcb 468 Description: merge in6pcb with inpcb 469 Status: Dormant 470 Start Date: Wed Feb 01 2006 471 End Date: 472 Base Tag: rpaulo-netinet-merge-pcb-base 473 Maintainer: Rui Paulo <rpaulo (a] NetBSD.org> 474 Scope: src/sys 475 Notes: No longer active due to the lack of time. If you plan to 476 continue this branch, sys/netinet/in_pcb.h already contains 477 the proposed structure layout (which was roughly discussed 478 in the tech-net mailing list). 479 I also defined INP_*() macros to mimicate FreeBSD's inpcb 480 locking style, but currently they do nothing and are not 481 yet called at the correct places (needs discussion about 482 kernel fine-grained locking). 483 To continue this branch, one needs to read all the relevant 484 inpcb/in6pcb source files and change the function names, 485 structure names, structure fields according to the new 486 layout (in6pcb is gone). 487 Don't try to build a kernel from this branch because it won't 488 work. The missing pieces required to do a complete build 489 were not committed because they were incomplete and generated 490 panics. 491 You shouldn't need to worry about KAME syncs because 492 they did most of them by now. 493 After the work is done, you are required to test the branch 494 (before the merge to -current) with an interop IPv6 test. 495 More info at: http://www.tahi.org/ 496 497 Branch: rtr-xorg-branch 498 Description: xorg & static build alterations to src/x11 499 Status: Active 500 Start Date: Nov 15 2004 501 End Date: 502 Base tag: rtr-xorg-branch-base 503 Maintainer: Tyler R.

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.

In terms of UBC, the primary cache for 1325 file data is the VM cache, which needs to operate 1326 in terms of VM pages. As no existing device has native 1327 pages the same size as our VM pages, there already is 1328 a mapping going on between the VM system and the 1329 underlying blocks. So it would be easier and cleaner 1330 to adjust that to deal w/ different block sizes. 1331 Also with UBC, all i/o is in terms of bytes at an offset 1332 with a certain length, so the exact block size isn't a big 1333 deal. 1334 1335 Any other wrstuden-devbsize tag may (and should) go away. 1336 1337 Branch: yamt-idlelwp 1338 Description: idle lwp, and some changes depending on it. 1339 1340 1. separate context switching and thread scheduling. 1341 (cf. gmcgarry_ctxsw) 1342 2. implement idle lwp. 1343 3. clean up related MD/MI interfaces. 1344 4. make scheduler(s) modular. 1345 1346 Status: Terminated; merged to -current 1347 Start Date: Fri Feb 17 2007 1348 End Date: Thu May 17 2007 1349 Base Tag: yamt-idlelwp-base8 1350 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 1351 Scope: src/sys (src/common is tagged but not branched) 1352 Notes: 1353 Status of ports: 1354 alpha [ Done, UP tested, MP not tested ] 1355 i386 [ Done, tested ] 1356 amd64 [ Done, tested ] 1357 mips [ Done, both MIPS1 and MIPS3 tested] 1358 sparc [ Done, UP tested, MP might have 1359 some problem after newlock2 merge ] 1360 sparc64 [ Done, tested ] 1361 arm [ Done, SA1 tested.
