1 # $NetBSD: BRANCHES,v 1.270 2008/12/07 12:57:00 ad 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: Active 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 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. 244 245 Branch: ad-audiomp2 246 Description: Add MP locking to the audio drivers 247 Status: Active 248 Start Date: 7 December 2008 249 End Date: 250 Base Tag: ad-audiomp2-base 251 Maintainer: Andrew Doran <ad (a] NetBSD.org> 252 Scope: kernel 253 Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 254 255 Branch: bjh21-hydra 256 Description: Simtec Hydra support and ARM SMP in general 257 Status: Dormant 258 Start Date: 18 Oct 2002 259 End Date: 260 Base Tag: bjh21-hydra-base 261 Maintainer: Ben Harris <bjh21 (a] NetBSD.org> 262 Scope: sys/arch/arm sys/arch/acorn32 263 Notes: This code was on a branch because it involves changes to 264 cpuswitch.S which would otherwise make merging the 265 nathanw_sa branch difficult. 266 267 Branch: chris-arm-intr-rework 268 Description: Rework arm interrupt handling code 269 Status: Active 270 Start Date: 11 Aug 2007 271 End Date: 272 Base Tag: chris-arm-intr-rework-base 273 Maintainer: Chris Gilbert <chris (a] NetBSD.org> 274 Scope: sys/arch/arm sys/arch/cats (other arm archs to follow) 275 Notes: Rework arm interrupt code to provide a shared set of interrupt 276 routines, and allow improvements to be shared across all arm 277 based hardware. 278 279 Branch: cube-autoconf 280 Description: Renovate autoconf(9) API 281 Status: Active 282 Start Date: 11 Dec 2007 283 End Date: 284 Base Tag: cube-autoconf-base 285 Maintainer: Quentin Garnier <cube (a] NetBSD.org> 286 Scope: kernel usr.bin/config (and some other userland bits) 287 Notes: Address a number of issues the current autoconf(9) API has. 288 289 Branch: gmcgarry_ctxsw 290 Description: Separate scheduler from context-switch code 291 Status: Dormant 292 Start Date: 18 December 2002 293 End Date: 294 Base Tag: gmcgarry_ctxsw_base 295 Maintainer: Gregory McGarry <gmcgarry (a] NetBSD.org> 296 Scope: kernel 297 Notes: Removing knowledge of the scheduler and its run queues 298 from the machine-dependent context switch code is the 299 first step in cleaning up the scheduler. It is necessary 300 for the newlock branch, making the scheduler SMP friendly, 301 adding real-time scheduler extensions, and reducing the 302 number of code paths for LWP and proc switching. 303 304 Branch: gmcgarry_ucred 305 Description: Integrate and encapsulate user credentials 306 Status: Dormant 307 Start Date: 18 December 2002 308 End Date: 309 Base Tag: gmcgarry_ucred_base 310 Maintainer: Gregory McGarry <gmcgarry (a] NetBSD.org> 311 Scope: kernel 312 Notes: merge pcred and ucred and poolify 313 314 Branch: haad-dm 315 Description: Add support for LVM to NetBSD 316 Status: Active 317 Start Date: 7 July 2008 318 End Date: 319 Base Tag: haad-dm-base 320 Maintainer: Adam Hamsik <haad (a] NetBSD.org> 321 Scope: kernel 322 Notes: LVM support is based on Linux lvm2tools, 323 libdevmapper library and NetBSD device-mapper 324 driver. 325 326 Branch: hpcarm-cleanup 327 Description: Fix build problems for hpcarm 328 Status: Active 329 Start Date: 31 July 2007 330 End Date: 331 Base Tag: hpcarm-cleanup-base 332 Maintainer: Robert Swindells <rjs (a] NetBSD.org> 333 Scope: kernel 334 Notes: Modify SA11x0 interrupt code to match PXA2x0 equivalent. 335 336 Branch: itohy-usb1 337 Description: USB stack overhaul, mostly DMA related 338 Status: Active 339 Start Date: 22 May 2007 340 End Date: 341 Base Tag: itohy-usb1-base 342 Maintainer: ITOH Yasufumi <itohy (a] NetBSD.org> 343 Scope: kernel 344 Notes: To check out the kernel source tree, 345 1. check out checkout script 346 cvs checkout -ritohy-usb1 src/sys/dev/usb/filelist 347 2. update files in the branch 348 sh -e src/sys/dev/usb/filelist 349 350 Branch: kame 351 Description: KAME Project 352 Status: Dormant 353 Start Date: 28 Jun 1999 354 End Date: 355 Base Tag: 356 Maintainer: Jun-ichiro itojun Hagino <itojun (a] NetBSD.org> 357 Scope: kernel 358 Notes: http://www.kame.net 359 Used for "reference" purposes for early part of KAME 360 integration effort.

The branch is 453 currently only the kernel, but will likely extend to some userland 454 areas. 455 456 Branch: pkgviews 457 Description: package views, enabling multiple conflicting packages to co-exist 458 Status: Active 459 Start Date: 22 July 2002 460 End Date: 461 Base Tag: pkgviews 462 Maintainer: Alistair Crooks <agc (a] NetBSD.org> 463 Scope: pkgsrc, basesrc/usr.sbin/pkg_install 464 Notes: A more flexible infrastructure for third-party packages by 465 allowing multiple conflicting packages and versions to co-exist 466 within the same tree 467 468 Branch: rpaulo-netinet-merge-pcb 469 Description: merge in6pcb with inpcb 470 Status: Dormant 471 Start Date: Wed Feb 01 2006 472 End Date: 473 Base Tag: rpaulo-netinet-merge-pcb-base 474 Maintainer: Rui Paulo <rpaulo (a] NetBSD.org> 475 Scope: src/sys 476 Notes: No longer active due to the lack of time. If you plan to 477 continue this branch, sys/netinet/in_pcb.h already contains 478 the proposed structure layout (which was roughly discussed 479 in the tech-net mailing list). 480 I also defined INP_*() macros to mimicate FreeBSD's inpcb 481 locking style, but currently they do nothing and are not 482 yet called at the correct places (needs discussion about 483 kernel fine-grained locking). 484 To continue this branch, one needs to read all the relevant 485 inpcb/in6pcb source files and change the function names, 486 structure names, structure fields according to the new 487 layout (in6pcb is gone). 488 Don't try to build a kernel from this branch because it won't 489 work. The missing pieces required to do a complete build 490 were not committed because they were incomplete and generated 491 panics. 492 You shouldn't need to worry about KAME syncs because 493 they did most of them by now. 494 After the work is done, you are required to test the branch 495 (before the merge to -current) with an interop IPv6 test. 496 More info at: http://www.tahi.org/ 497 498 Branch: rtr-xorg-branch 499 Description: xorg & static build alterations to src/x11 500 Status: Active 501 Start Date: Nov 15 2004 502 End Date: 503 Base tag: rtr-xorg-branch-base 504 Maintainer: Tyler R.

Improvements 526 include not allocating memory while preparing to tsleep(), 527 reducing inappropriate upcall delivery (hopefully also 528 eliminating the need to mlock stacks), and being 529 able to pthread_kill() running threads. At this date, 530 most goals have been achieved.

In terms of UBC, the primary cache for 1314 file data is the VM cache, which needs to operate 1315 in terms of VM pages. As no existing device has native 1316 pages the same size as our VM pages, there already is 1317 a mapping going on between the VM system and the 1318 underlying blocks. So it would be easier and cleaner 1319 to adjust that to deal w/ different block sizes. 1320 Also with UBC, all i/o is in terms of bytes at an offset 1321 with a certain length, so the exact block size isn't a big 1322 deal. 1323 1324 Any other wrstuden-devbsize tag may (and should) go away. 1325 1326 Branch: yamt-idlelwp 1327 Description: idle lwp, and some changes depending on it. 1328 1329 1. separate context switching and thread scheduling. 1330 (cf. gmcgarry_ctxsw) 1331 2. implement idle lwp. 1332 3. clean up related MD/MI interfaces. 1333 4. make scheduler(s) modular. 1334 1335 Status: Terminated; merged to -current 1336 Start Date: Fri Feb 17 2007 1337 End Date: Thu May 17 2007 1338 Base Tag: yamt-idlelwp-base8 1339 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 1340 Scope: src/sys (src/common is tagged but not branched) 1341 Notes: 1342 Status of ports: 1343 alpha [ Done, UP tested, MP not tested ] 1344 i386 [ Done, tested ] 1345 amd64 [ Done, tested ] 1346 mips [ Done, both MIPS1 and MIPS3 tested] 1347 sparc [ Done, UP tested, MP might have 1348 some problem after newlock2 merge ] 1349 sparc64 [ Done, tested ] 1350 arm [ Done, SA1 tested.
