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 initializtion, 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: gmcgarry_ctxsw 258 Description: Separate scheduler from context-switch code 259 Status: Dormant 260 Start Date: 18 December 2002 261 End Date: 262 Base Tag: gmcgarry_ctxsw_base 263 Maintainer: Gregory McGarry <gmcgarry (a] NetBSD.org> 264 Scope: kernel 265 Notes: Removing knowledge of the schedular and its run queues 266 from the machine-dependent context switch code is the 267 first step in cleaning up the scheduler. It is necessary 268 for the newlock branch, making the scheduler SMP friendly, 269 adding real-time scheduler extensions, and reducing the 270 number of code paths for LWP and proc switching. 271 272 Branch: gmcgarry_ucred 273 Description: Integrate and encapsulate user credentials 274 Status: Dormant 275 Start Date: 18 December 2002 276 End Date: 277 Base Tag: gmcgarry_ucred_base 278 Maintainer: Gregory McGarry <gmcgarry (a] NetBSD.org> 279 Scope: kernel 280 Notes: merge pcred and ucred and poolify 281 282 Branch: kame 283 Description: KAME Project 284 Status: Dormant 285 Start Date: 28 Jun 1999 286 End Date: 287 Base Tag: 288 Maintainer: Jun-ichiro itojun Hagino <itojun (a] NetBSD.org> 289 Scope: kernel 290 Notes: http://www.kame.net 291 Used for "reference" purposes for early part of KAME 292 integration effort. The branch is not actively used, as I 293 (itojun) use patch(1) and diff(1) for the KAME syncs. 294 295 Branch: kent-audio2 296 Description: In-kernel audio mixer 297 Status: Active 298 Start Date: Sun Jan 16 2005 299 End Date: 300 Base Tag: kent-audio2-base 301 Maintainer: TAMURA Kent <kent (a] NetBSD.org> 302 Scope: kernel (audio device drivers) 303 Notes: http://mail-index.netbsd.org/tech-kern/2004/12/03/0007.html 304 Please consult with the maintainer before committing 305 to this branch. 306 This branch is not expected to be compilable yet. 307 308 Branch: matt-timespec 309 Description: Convert the kernel to struct timespec as its primary time 310 storage mechanism. 311 Status: Active 312 Start Date: 2005-02-19 313 End Date: 314 Base Tag: 315 Maintainer: Matt Thomas <matt (a] NetBSD.org> 316 Scope: kernel 317 Notes: 318 319 Branch: newlock 320 Description: New locking primitives, based on Solaris's 321 Status: Terminated 322 Start Date: March 9, 2002 323 End Date: Febuary 12, 2007 324 Base Tag: newlock-base 325 Maintainer: Jason R. Thorpe <thorpej (a] NetBSD.org> 326 Scope: Kernel 327 Notes: The goal is to replace the existing lockmgr() and 328 simple_lock() based locking mechanisms with the 329 primitives found in Solaris: mutexes and rwlocks. 330 Superseeded by the newlock2 branch. 331 332 Branch: newlock2 333 Description: New locking primitives, based on Solaris's 334 Status: Terminated 335 Start Date: September 9, 2006 336 End Date: Febuary 12, 2007 337 Base Tag: newlock2-base 338 Maintainer: Andrew Doran <ad (a] NetBSD.org> 339 Scope: Kernel 340 Notes: As per the newlock branch, however given the amount of time 341 the original branch has lain dormant, a new one has been 342 created. Goals: 343 - Implement new locking primitives on most-used ports. 344 - Minor locking improvements. 345 - Remove spinlockmgr(). 346 347 Branch: pkgviews 348 Description: package views, enabling multiple conflicting packages to co-exist 349 Status: Active 350 Start Date: 22 July 2002 351 End Date: 352 Base Tag: pkgviews 353 Maintainer: Alistair Crooks <agc (a] NetBSD.org> 354 Scope: pkgsrc, basesrc/usr.sbin/pkg_install 355 Notes: A more flexible infrastructure for third-party packages by 356 allowing multiple conflicting packages and versions to co-exist 357 within the same tree 358 359 Branch: rpaulo-netinet-merge-pcb 360 Description: merge in6pcb with inpcb 361 Status: Dormant 362 Start Date: Wed Feb 01 2006 363 End Date: 364 Base Tag: rpaulo-netinet-merge-pcb-base 365 Maintainer: Rui Paulo <rpaulo (a] NetBSD.org> 366 Scope: src/sys 367 Notes: No longer active due to the lack of time. If you plan to 368 continue this branch, sys/netinet/in_pcb.h already contains 369 the proposed structure layout (which was roughly discussed 370 in the tech-net mailing list). 371 I also defined INP_*() macros to mimicate FreeBSD's inpcb 372 locking style, but currently they do nothing and are not 373 yet called at the correct places (needs discussion about 374 kernel fine-grained locking). 375 To continue this branch, one needs to read all the relevant 376 inpcb/in6pcb source files and change the function names, 377 structure names, structure fileds according to the new 378 layout (in6pcb is gone). 379 Don't try to build a kernel from this branch because it won't 380 work. The missing pieces required to do a complete build 381 were not committed because they were incomplete and generated 382 panics. 383 You shouldn't need to worry about KAME syncs because 384 they did most of them by now. 385 After the work is done, you are required to test the branch 386 (before the merge to -current) with an interop IPv6 test. 387 More info at: http://www.tahi.org/ 388 389 Branch: rtr-xorg-branch 390 Description: xorg & static build alterations to src/x11 391 Status: Active 392 Start Date: Nov 15 2004 393 End Date: 394 Base tag: rtr-xorg-branch-base 395 Maintainer: Tyler R.

Most per architecture 436 changes need to be made in the pmap module. LFS is not 437 currently stable due interaction between the pagedaemon (?) 438 and the HOLDRELE() in lfs_segment.c. It may trash your 439 filesystem.. 440 441 Most of the locks replaced are now sleep/adaptive locks or 442 spin locks at IPL_VM. Assuming audio interrupt handlers 443 are made MP safe there are far fewer potential deadlocks 444 against the kernel lock. 445 446 v_interlock becomes an adaptive mutex so now acquring 447 it can potentially block, similarly for other locks 448 that were before simplelocks. This needs to be audited 449 carefully. 450 451 Use vnodes in general needs to be audited, as vnodes can 452 now be inspected without the kernel lock held. 453 454 Acquiring locks in the pmap module can now block, meaning 455 that the current pmap, cpu or lazy pmap status can change 456 out from underneath the requestor.

So it would be easier and cleaner 958 to adjust that to deal w/ different block sizes. 959 Also with UBC, all i/o is in terms of bytes at an offset 960 with a certain length, so the exact block size isn't a big 961 deal. 962 963 Any other wrstuden-devbsize tag may (and should) go away. 964 965 Branch: yamt-km, yamt-km-doc 966 Description: simplify/improve kernel memory management and bootstrap 967 Status: Terminated; merged to -current 968 Start Date: Tue Jan 25 2005 969 End Date: Fri Apr 1 2005 970 Base Tag: yamt-km-base{,2,3,4}, yamt-km-doc-base 971 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 972 Scope: yamt-km: src/sys 973 yamt-km-doc: src/share/man/man9/uvm.9 974 Notes: http://mail-index.NetBSD.org/tech-kern/2004/12/25/0005.html 975 976 the followings are per-port status. 977 (account names mean "tested by".) 978 979 works enough to go to multiuser: 980 alpha, i386, xen (yamt@) 981 pc532 (simonb@) 982 alpha, i386, mac68k, macppc, pmax, shark, 983 sparc, sparc64, sun3, x68k (chs@) 984 cobalt, dreamcast, hp300, news68k, newsmips, 985 sun3x (tsutsui@) 986 amiga (mhitch@) 987 cats, hp700 (skrll@) 988 xen (bouyer@) 989 990 known to have the same problem as trunk: 991 vax (chs@, stuck while running kvm_mkdb) 992 993 known to have a problem: 994 luna68k (and, if any, other m68k ports which use TTR) 995 needs to be revisited. 996 -> for luna68k, although not tested, 997 Sysmap has been moved to avoid kva conflict with 998 I/O ranges. 999 1000 buildable: 1001 src/sys/arch/acorn26/conf/GENERIC 1002 src/sys/arch/acorn32/conf/GENERIC 1003 src/sys/arch/algor/conf/P6032 1004 src/sys/arch/alpha/conf/GENERIC 1005 src/sys/arch/alpha/conf/GENERIC.MP 1006 src/sys/arch/amd64/conf/GENERIC 1007 src/sys/arch/amd64/conf/GENERIC.MP 1008 src/sys/arch/amiga/conf/GENERIC 1009 src/sys/arch/arc/conf/GENERIC 1010 src/sys/arch/atari/conf/MILAN-PCIIDE 1011 src/sys/arch/bebox/conf/GENERIC 1012 src/sys/arch/cats/conf/GENERIC 1013 src/sys/arch/cesfic/conf/GENERIC 1014 src/sys/arch/cobalt/conf/GENERIC 1015 src/sys/arch/dreamcast/conf/GENERIC 1016 src/sys/arch/evbarm/conf/TS7200 1017 src/sys/arch/evbppc/conf/WALNUT 1018 src/sys/arch/evbsh3/conf/COMPUTEXEVB 1019 src/sys/arch/evbsh5/conf/CAYMAN64 1020 src/sys/arch/hp300/conf/GENERIC 1021 src/sys/arch/hp700/conf/GENERIC 1022 src/sys/arch/hpcarm/conf/JORNADA728 1023 src/sys/arch/hpcmips/conf/GENERIC 1024 src/sys/arch/hpcsh/conf/GENERIC 1025 src/sys/arch/hpcsh/conf/HPW650PA 1026 src/sys/arch/i386/conf/GENERIC 1027 src/sys/arch/i386/conf/GENERIC.MP 1028 src/sys/arch/i386/conf/XEN0 1029 src/sys/arch/i386/conf/XENU 1030 src/sys/arch/ibmnws/conf/GENERIC 1031 src/sys/arch/iyonix/conf/GENERIC 1032 src/sys/arch/luna68k/conf/GENERIC 1033 src/sys/arch/mac68k/conf/GENERIC 1034 src/sys/arch/macppc/conf/GENERIC 1035 src/sys/arch/macppc/conf/GENERIC.MP 1036 src/sys/arch/mipsco/conf/GENERIC 1037 src/sys/arch/mmeye/conf/GENERIC 1038 src/sys/arch/mvme68k/conf/GENERIC 1039 src/sys/arch/netwinder/conf/GENERIC 1040 src/sys/arch/news68k/conf/GENERIC 1041 src/sys/arch/newsmips/conf/GENERIC 1042 src/sys/arch/next68k/conf/GENERIC 1043 src/sys/arch/ofppc/conf/GENERIC 1044 src/sys/arch/pc532/conf/GENERIC 1045 src/sys/arch/pmax/conf/GENERIC 1046 src/sys/arch/prep/conf/GENERIC 1047 src/sys/arch/sandpoint/conf/GENERIC 1048 src/sys/arch/sbmips/conf/GENERIC 1049 src/sys/arch/sgimips/conf/GENERIC32_IP3x 1050 src/sys/arch/shark/conf/GENERIC 1051 src/sys/arch/sparc/conf/GENERIC 1052 src/sys/arch/sparc/conf/GENERIC.MP 1053 src/sys/arch/sparc64/conf/GENERIC 1054 src/sys/arch/sparc64/conf/GENERIC.MP 1055 src/sys/arch/sun2/conf/GENERIC 1056 src/sys/arch/sun3/conf/GENERIC 1057 src/sys/arch/vax/conf/GENERIC 1058 src/sys/arch/vax/conf/GENERIC.MP 1059 src/sys/arch/x68k/conf/GENERIC 1060 1061 src/sys/arch/playstation2/conf/GENERIC 1062 1063 Branch: yamt-pdpolicy 1064 Description: play with page replacement policy 1065 - separate page replacement policy from the rest of kernel 1066 - implement alternative replacement policy 1067 - related read-ahead adjustment?
