1 # $NetBSD: BRANCHES,v 1.228 2007/12/11 22:57:44 bouyer 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: bjh21-hydra 246 Description: Simtec Hydra support and ARM SMP in general 247 Status: Dormant 248 Start Date: 18 Oct 2002 249 End Date: 250 Base Tag: bjh21-hydra-base 251 Maintainer: Ben Harris <bjh21 (a] NetBSD.org> 252 Scope: sys/arch/arm sys/arch/acorn32 253 Notes: This code was on a branch because it involves changes to 254 cpuswitch.S which would otherwise make merging the 255 nathanw_sa branch difficult. 256 257 Branch: bouyer-xeni386 258 Description: switch xen on i386 to the x86 pmap and the xen/x86/x86_xpmap.c bootstrap, and add i386 PAE support 259 Status: Active 260 Start Date: 10 Dec 2007 261 End Date: 262 Base Tag: bouyer-xeni386-base 263 Maintainer: Manuel Bouyer <bouyer (a] NetBSD.org> 264 Scope: kernel 265 Notes: 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: gmcgarry_ctxsw 280 Description: Separate scheduler from context-switch code 281 Status: Dormant 282 Start Date: 18 December 2002 283 End Date: 284 Base Tag: gmcgarry_ctxsw_base 285 Maintainer: Gregory McGarry <gmcgarry (a] NetBSD.org> 286 Scope: kernel 287 Notes: Removing knowledge of the scheduler and its run queues 288 from the machine-dependent context switch code is the 289 first step in cleaning up the scheduler. It is necessary 290 for the newlock branch, making the scheduler SMP friendly, 291 adding real-time scheduler extensions, and reducing the 292 number of code paths for LWP and proc switching. 293 294 Branch: gmcgarry_ucred 295 Description: Integrate and encapsulate user credentials 296 Status: Dormant 297 Start Date: 18 December 2002 298 End Date: 299 Base Tag: gmcgarry_ucred_base 300 Maintainer: Gregory McGarry <gmcgarry (a] NetBSD.org> 301 Scope: kernel 302 Notes: merge pcred and ucred and poolify 303 304 Branch: hpcarm-cleanup 305 Description: Fix build problems for hpcarm 306 Status: Active 307 Start Date: 31 July 2007 308 End Date: 309 Base Tag: hpcarm-cleanup-base 310 Maintainer: Robert Swindells <rjs (a] NetBSD.org> 311 Scope: kernel 312 Notes: Modify SA11x0 interrupt code to match PXA2x0 equivalent. 313 314 Branch: itohy-usb1 315 Description: USB stack overhaul, mostly DMA related 316 Status: Active 317 Start Date: 22 May 2007 318 End Date: 319 Base Tag: itohy-usb1-base 320 Maintainer: ITOH Yasufumi <itohy (a] NetBSD.org> 321 Scope: kernel 322 Notes: To check out the kernel source tree, 323 1. check out checkout script 324 cvs checkout -ritohy-usb1 src/sys/dev/usb/filelist 325 2. update files in the branch 326 sh -e src/sys/dev/usb/filelist 327 328 Branch: kame 329 Description: KAME Project 330 Status: Dormant 331 Start Date: 28 Jun 1999 332 End Date: 333 Base Tag: 334 Maintainer: Jun-ichiro itojun Hagino <itojun (a] NetBSD.org> 335 Scope: kernel 336 Notes: http://www.kame.net 337 Used for "reference" purposes for early part of KAME 338 integration effort.

If you plan to 431 continue this branch, sys/netinet/in_pcb.h already contains 432 the proposed structure layout (which was roughly discussed 433 in the tech-net mailing list). 434 I also defined INP_*() macros to mimicate FreeBSD's inpcb 435 locking style, but currently they do nothing and are not 436 yet called at the correct places (needs discussion about 437 kernel fine-grained locking). 438 To continue this branch, one needs to read all the relevant 439 inpcb/in6pcb source files and change the function names, 440 structure names, structure fields according to the new 441 layout (in6pcb is gone). 442 Don't try to build a kernel from this branch because it won't 443 work. The missing pieces required to do a complete build 444 were not committed because they were incomplete and generated 445 panics. 446 You shouldn't need to worry about KAME syncs because 447 they did most of them by now. 448 After the work is done, you are required to test the branch 449 (before the merge to -current) with an interop IPv6 test. 450 More info at: http://www.tahi.org/ 451 452 Branch: rtr-xorg-branch 453 Description: xorg & static build alterations to src/x11 454 Status: Active 455 Start Date: Nov 15 2004 456 End Date: 457 Base tag: rtr-xorg-branch-base 458 Maintainer: Tyler R.

Improvements 480 include not allocating memory while preparing to tsleep(), 481 reducing inappropriate upcall delivery (hopefully also 482 eliminating the need to mlock stacks), and being 483 able to pthread_kill() running threads. 484 485 Branch: vmlocking 486 Description: Make VM and file system framework MP safe 487 Status: Terminated 488 Start Date: 13 March 2007 489 End Date: 4 December 2007 490 Base Tag: vmlocking-base 491 Maintainer: Andrew Doran <ad (a] NetBSD.org> 492 Scope: kernel 493 Notes: Superseded by vmlocking2 branch. 494 495 Branch: vmlocking2 496 Description: Make VM and file system framework MP safe 497 Status: Active 498 Start Date: 4 December 2007 499 End Date: 500 Base Tag: vmlocking2-base1 501 Maintainer: Andrew Doran <ad (a] NetBSD.org> 502 Scope: kernel 503 Notes: Goals: 504 505 - Make VM system / trap handling MP safe. 506 - Replace simplelocks with mutexes. 507 - Make file system framework MP safe. 508 509 Status by architecture: 510 511 alpha partial: need pmap/trap locking changes 512 i386 done 513 amd64 done 514 mips done 515 sparc 516 sparc64 517 arm 518 powerpc partial: need pmap/trap locking changes 519 hppa done 520 sh3 done 521 vax partial: need pmap/trap locking changes 522 m68k 523 xen partial 524 525 Remaining MI work to do: 526 527 - Document locking around fields in struct mount. 528 529 - Check aliased vnode handling.

It's needed for !kmem_map 539 because sometimes allocations are made by threads that 540 hold the map locked, which could cause other threads to 541 wait long term even if they are trying to make a NOWAIT 542 allocation. 543 544 - ext2fs dup alloc. 545 546 - Unmount erroneously reports busy sometimes.

In terms of UBC, the primary cache for 1227 file data is the VM cache, which needs to operate 1228 in terms of VM pages. As no existing device has native 1229 pages the same size as our VM pages, there already is 1230 a mapping going on between the VM system and the 1231 underlying blocks. So it would be easier and cleaner 1232 to adjust that to deal w/ different block sizes. 1233 Also with UBC, all i/o is in terms of bytes at an offset 1234 with a certain length, so the exact block size isn't a big 1235 deal. 1236 1237 Any other wrstuden-devbsize tag may (and should) go away. 1238 1239 Branch: yamt-idlelwp 1240 Description: idle lwp, and some changes depending on it. 1241 1242 1. separate context switching and thread scheduling. 1243 (cf. gmcgarry_ctxsw) 1244 2. implement idle lwp. 1245 3. clean up related MD/MI interfaces. 1246 4. make scheduler(s) modular. 1247 1248 Status: Terminated; merged to -current 1249 Start Date: Fri Feb 17 2007 1250 End Date: Thu May 17 2007 1251 Base Tag: yamt-idlelwp-base8 1252 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 1253 Scope: src/sys (src/common is tagged but not branched) 1254 Notes: 1255 Status of ports: 1256 alpha [ Done, UP tested, MP not tested ] 1257 i386 [ Done, tested ] 1258 amd64 [ Done, tested ] 1259 mips [ Done, both MIPS1 and MIPS3 tested] 1260 sparc [ Done, UP tested, MP might have 1261 some problem after newlock2 merge ] 1262 sparc64 [ Done, tested ] 1263 arm [ Done, SA1 tested.
