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: 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: hpcarm-cleanup 315 Description: Fix build problems for hpcarm 316 Status: Active 317 Start Date: 31 July 2007 318 End Date: 319 Base Tag: hpcarm-cleanup-base 320 Maintainer: Robert Swindells <rjs (a] NetBSD.org> 321 Scope: kernel 322 Notes: Modify SA11x0 interrupt code to match PXA2x0 equivalent. 323 324 Branch: itohy-usb1 325 Description: USB stack overhaul, mostly DMA related 326 Status: Active 327 Start Date: 22 May 2007 328 End Date: 329 Base Tag: itohy-usb1-base 330 Maintainer: ITOH Yasufumi <itohy (a] NetBSD.org> 331 Scope: kernel 332 Notes: To check out the kernel source tree, 333 1. check out checkout script 334 cvs checkout -ritohy-usb1 src/sys/dev/usb/filelist 335 2. update files in the branch 336 sh -e src/sys/dev/usb/filelist 337 338 Branch: kame 339 Description: KAME Project 340 Status: Dormant 341 Start Date: 28 Jun 1999 342 End Date: 343 Base Tag: 344 Maintainer: Jun-ichiro itojun Hagino <itojun (a] NetBSD.org> 345 Scope: kernel 346 Notes: http://www.kame.net 347 Used for "reference" purposes for early part of KAME 348 integration effort.

If you plan to 441 continue this branch, sys/netinet/in_pcb.h already contains 442 the proposed structure layout (which was roughly discussed 443 in the tech-net mailing list). 444 I also defined INP_*() macros to mimicate FreeBSD's inpcb 445 locking style, but currently they do nothing and are not 446 yet called at the correct places (needs discussion about 447 kernel fine-grained locking). 448 To continue this branch, one needs to read all the relevant 449 inpcb/in6pcb source files and change the function names, 450 structure names, structure fields according to the new 451 layout (in6pcb is gone). 452 Don't try to build a kernel from this branch because it won't 453 work. The missing pieces required to do a complete build 454 were not committed because they were incomplete and generated 455 panics. 456 You shouldn't need to worry about KAME syncs because 457 they did most of them by now. 458 After the work is done, you are required to test the branch 459 (before the merge to -current) with an interop IPv6 test. 460 More info at: http://www.tahi.org/ 461 462 Branch: rtr-xorg-branch 463 Description: xorg & static build alterations to src/x11 464 Status: Active 465 Start Date: Nov 15 2004 466 End Date: 467 Base tag: rtr-xorg-branch-base 468 Maintainer: Tyler R.

Improvements 490 include not allocating memory while preparing to tsleep(), 491 reducing inappropriate upcall delivery (hopefully also 492 eliminating the need to mlock stacks), and being 493 able to pthread_kill() running threads. 494 495 Branch: vmlocking 496 Description: Make VM and file system framework MP safe 497 Status: Terminated 498 Start Date: 13 March 2007 499 End Date: 4 December 2007 500 Base Tag: vmlocking-base 501 Maintainer: Andrew Doran <ad (a] NetBSD.org> 502 Scope: kernel 503 Notes: Superseded by vmlocking2 branch. 504 505 Branch: vmlocking2 506 Description: Make VM and file system framework MP safe 507 Status: Active 508 Start Date: 4 December 2007 509 End Date: 510 Base Tag: vmlocking2-base1 511 Maintainer: Andrew Doran <ad (a] NetBSD.org> 512 Scope: kernel 513 Notes: Goals: 514 515 - Make VM system / trap handling MP safe. 516 - Replace simplelocks with mutexes. 517 - Make file system framework MP safe. 518 519 Status by architecture: 520 521 alpha partial: need pmap/trap locking changes 522 i386 done 523 amd64 done 524 mips done 525 sparc 526 sparc64 done 527 arm 528 powerpc partial: need pmap/trap locking changes 529 hppa done 530 sh3 done 531 vax partial: need pmap/trap locking changes 532 m68k 533 xen partial 534 535 Remaining MI work to do: 536 537 - Check aliased vnode handling.

In terms of UBC, the primary cache for 1223 file data is the VM cache, which needs to operate 1224 in terms of VM pages. As no existing device has native 1225 pages the same size as our VM pages, there already is 1226 a mapping going on between the VM system and the 1227 underlying blocks. So it would be easier and cleaner 1228 to adjust that to deal w/ different block sizes. 1229 Also with UBC, all i/o is in terms of bytes at an offset 1230 with a certain length, so the exact block size isn't a big 1231 deal. 1232 1233 Any other wrstuden-devbsize tag may (and should) go away. 1234 1235 Branch: yamt-idlelwp 1236 Description: idle lwp, and some changes depending on it. 1237 1238 1. separate context switching and thread scheduling. 1239 (cf. gmcgarry_ctxsw) 1240 2. implement idle lwp. 1241 3. clean up related MD/MI interfaces. 1242 4. make scheduler(s) modular. 1243 1244 Status: Terminated; merged to -current 1245 Start Date: Fri Feb 17 2007 1246 End Date: Thu May 17 2007 1247 Base Tag: yamt-idlelwp-base8 1248 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 1249 Scope: src/sys (src/common is tagged but not branched) 1250 Notes: 1251 Status of ports: 1252 alpha [ Done, UP tested, MP not tested ] 1253 i386 [ Done, tested ] 1254 amd64 [ Done, tested ] 1255 mips [ Done, both MIPS1 and MIPS3 tested] 1256 sparc [ Done, UP tested, MP might have 1257 some problem after newlock2 merge ] 1258 sparc64 [ Done, tested ] 1259 arm [ Done, SA1 tested.
