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 47Branch: comdex-fall-1999 48Description: Special release branch for pre-1.5 release at 49 Fall 1999 COMDEX. 50Status: Terminated 51Start Date: 52End Date: 53Base Tag: comdex-fall-1999-base 54Maintainer: ? 55Scope: Entire tree. 56Notes: 57 58Branch: netbsd-0-9 59Description: The NetBSD 0.9 release branch 60Status: Terminated 61Start Date: 62End Date: 63Base Tag: netbsd-0-9-base 64Maintainer: Release Engineering <releng@NetBSD.org> 65Scope: Entire tree. 66Notes: 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 70Branch: netbsd-1-0 71Description: The NetBSD 1.0 release branch 72Status: Terminated 73Start Date: 74End Date: 75Base Tag: netbsd-1-0-base 76Maintainer: Release Engineering <releng@NetBSD.org> 77Scope: Entire tree. 78Notes: 79 Commits restricted to release engineering. 80 81Branch: netbsd-1-1 82Description: The NetBSD 1.1 release branch 83Status: Terminated 84Start Date: 85End Date: 86Base Tag: netbsd-1-1-base 87Maintainer: Release Engineering <releng@NetBSD.org> 88Scope: Entire tree. 89Notes: 90 Commits restricted to release engineering. 91 92Branch: netbsd-1-2 93Description: The NetBSD 1.2 release branch 94Status: Terminated 95Start Date: 96End Date: 97Base Tag: netbsd-1-2-base 98Maintainer: Release Engineering <releng@NetBSD.org> 99Scope: Entire tree. 100Notes: 101 Commits restricted to release engineering. 102 103Branch: netbsd-1-3 104Description: The NetBSD 1.3 release branch 105Status: Terminated 106Start Date: 107End Date: 108Base Tag: netbsd-1-3-base 109Maintainer: Release Engineering <releng@NetBSD.org> 110Scope: Entire tree. 111Notes: 112 Commits restricted to release engineering. 113 114Branch: netbsd-1-4 115Description: The NetBSD 1.4 release branch 116Status: Terminated 117Start Date: 1 Apr 2000 118End Date: 119Base Tag: netbsd-1-4-base 120Maintainer: 1.4 Release Engineering <releng-1-4@NetBSD.org> 121Scope: Entire tree. 122Notes: 123 Commits restricted to release engineering. 124 125Branch: netbsd-1-5 126Description: The NetBSD 1.5 release branch 127Status: Terminated 128Start Date: 20 Jun 2000 129End Date: 26 Jan 2005 130Base Tag: netbsd-1-5-base 131Maintainer: 1.5 Release Engineering <releng-1-5@NetBSD.org> 132Scope: Entire tree. 133Notes: 134 Commits restricted to release engineering. 135 136Branch: netbsd-1-6 137Description: The NetBSD 1.6 release branch 138Status: Terminated 139Start Date: 22 May 2002 140End Date: 141Base Tag: netbsd-1-6-base 142Maintainer: 1.6 Release Engineering <releng-1-6@NetBSD.org> 143Scope: Entire tree. 144Notes: 145 Commits restricted to Release Engineering. 146 147Branch: netbsd-2 148Description: The NetBSD 2 release branch 149Status: Active 150Start Date: 23 Dec 2004 151End Date: 152Base Tag: netbsd-2-base 153Maintainer: 2 Release Engineering <releng-2@NetBSD.org> 154Scope: 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 245Branch: bjh21-hydra 246Description: Simtec Hydra support and ARM SMP in general 247Status: Dormant 248Start Date: 18 Oct 2002 249End Date: 250Base Tag: bjh21-hydra-base 251Maintainer: Ben Harris <bjh21@NetBSD.org> 252Scope: sys/arch/arm sys/arch/acorn32 253Notes: 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 257Branch: gmcgarry_ctxsw 258Description: Separate scheduler from context-switch code 259Status: Dormant 260Start Date: 18 December 2002 261End Date: 262Base Tag: gmcgarry_ctxsw_base 263Maintainer: Gregory McGarry <gmcgarry@NetBSD.org> 264Scope: kernel 265Notes: 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 272Branch: gmcgarry_ucred 273Description: Integrate and encapsulate user credentials 274Status: Dormant 275Start Date: 18 December 2002 276End Date: 277Base Tag: gmcgarry_ucred_base 278Maintainer: Gregory McGarry <gmcgarry@NetBSD.org> 279Scope: kernel 280Notes: merge pcred and ucred and poolify 281 282Branch: kame 283Description: KAME Project 284Status: Dormant 285Start Date: 28 Jun 1999 286End Date: 287Base Tag: 288Maintainer: Jun-ichiro itojun Hagino <itojun@NetBSD.org> 289Scope: kernel 290Notes: http://www.kame.net 291 Used for "reference" purposes for early part of KAME 292 integration effort.

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 389Branch: rtr-xorg-branch 390Description: xorg & static build alterations to src/x11 391Status: Active 392Start Date: Nov 15 2004 393End Date: 394Base tag: rtr-xorg-branch-base 395Maintainer: Tyler R.

Most per architecture 421 changes need to be made in the pmap module. LFS is not 422 currently stable due interaction between the pagedaemon (?) 423 and the HOLDRELE() in lfs_segment.c. It may trash your 424 filesystem.. 425 426 Most of the locks replaced are now sleep/adaptive locks or 427 spin locks at IPL_VM. Assuming audio interrupt handlers 428 are made MP safe there are far fewer potential deadlocks 429 against the kernel lock. 430 431 v_interlock becomes an adaptive mutex so now acquring 432 it can potentially block, similarly for other locks 433 that were before simplelocks. This needs to be audited 434 carefully. 435 436 Use vnodes in general needs to be audited, as vnodes can 437 now be inspected without the kernel lock held. 438 439 Acquiring locks in the pmap module can now block, meaning 440 that the current pmap, cpu or lazy pmap status can change 441 out from underneath the requestor. This also needs to be 442 audited. 443 444 Currently, i386 has the necessary modifications, and has 445 trap handling and a few calls to allocators out from under 446 the kernel lock. There are still problems that need to be 447 debugged. 448 449 Need to check that whenever a lock is initialized, it is 450 also destroyed. 451 452 Lots of testing required. 453 454Branch: yamt-idlelwp 455Description: idle lwp, and some changes depending on it. 456 457 1. separate context switching and thread scheduling. 458 (cf. gmcgarry_ctxsw) 459 2. implement idle lwp. 460 3. clean up related MD/MI interfaces. 461 4. make scheduler(s) modular. 462 463Status: Active 464Start Date: Fri Feb 17 2007 465End Date: 466Base Tag: yamt-idlelwp-base4 467Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 468Scope: src/sys (src/common is tagged but not branched) 469Notes: 470 Status of ports (minimal goals): 471 alpha [ Done, 472 UP tested, MP not tested ] 473 i386 [ Done, tested ] 474 amd64 [ Done, tested ] 475 mips [ WIP ] 476 sparc [ WIP ] 477 sparc64 [ WIP ] 478 arm [ Done. 479 SA1 tested. ] 480 macppc/powerpc [ Done, OEA tested ] 481 hppa [ WIP ] 482 sh3 [ Done, tested ] 483 vax [ Done, UP tested, MP untested ] 484 485 How to adapt a port?

In terms of UBC, the primary cache for 1038 file data is the VM cache, which needs to operate 1039 in terms of VM pages. As no existing device has native 1040 pages the same size as our VM pages, there already is 1041 a mapping going on between the VM system and the 1042 underlying blocks. So it would be easier and cleaner 1043 to adjust that to deal w/ different block sizes. 1044 Also with UBC, all i/o is in terms of bytes at an offset 1045 with a certain length, so the exact block size isn't a big 1046 deal. 1047 1048 Any other wrstuden-devbsize tag may (and should) go away. 1049 1050Branch: yamt-km, yamt-km-doc 1051Description: simplify/improve kernel memory management and bootstrap 1052Status: Terminated; merged to -current 1053Start Date: Tue Jan 25 2005 1054End Date: Fri Apr 1 2005 1055Base Tag: yamt-km-base{,2,3,4}, yamt-km-doc-base 1056Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1057Scope: yamt-km: src/sys 1058 yamt-km-doc: src/share/man/man9/uvm.9 1059Notes: http://mail-index.NetBSD.org/tech-kern/2004/12/25/0005.html 1060 1061 the followings are per-port status. 1062 (account names mean "tested by".) 1063 1064 works enough to go to multiuser: 1065 alpha, i386, xen (yamt@) 1066 pc532 (simonb@) 1067 alpha, i386, mac68k, macppc, pmax, shark, 1068 sparc, sparc64, sun3, x68k (chs@) 1069 cobalt, dreamcast, hp300, news68k, newsmips, 1070 sun3x (tsutsui@) 1071 amiga (mhitch@) 1072 cats, hp700 (skrll@) 1073 xen (bouyer@) 1074 1075 known to have the same problem as trunk: 1076 vax (chs@, stuck while running kvm_mkdb) 1077 1078 known to have a problem: 1079 luna68k (and, if any, other m68k ports which use TTR) 1080 needs to be revisited. 1081 -> for luna68k, although not tested, 1082 Sysmap has been moved to avoid kva conflict with 1083 I/O ranges. 1084 1085 buildable: 1086 src/sys/arch/acorn26/conf/GENERIC 1087 src/sys/arch/acorn32/conf/GENERIC 1088 src/sys/arch/algor/conf/P6032 1089 src/sys/arch/alpha/conf/GENERIC 1090 src/sys/arch/alpha/conf/GENERIC.MP 1091 src/sys/arch/amd64/conf/GENERIC 1092 src/sys/arch/amd64/conf/GENERIC.MP 1093 src/sys/arch/amiga/conf/GENERIC 1094 src/sys/arch/arc/conf/GENERIC 1095 src/sys/arch/atari/conf/MILAN-PCIIDE 1096 src/sys/arch/bebox/conf/GENERIC 1097 src/sys/arch/cats/conf/GENERIC 1098 src/sys/arch/cesfic/conf/GENERIC 1099 src/sys/arch/cobalt/conf/GENERIC 1100 src/sys/arch/dreamcast/conf/GENERIC 1101 src/sys/arch/evbarm/conf/TS7200 1102 src/sys/arch/evbppc/conf/WALNUT 1103 src/sys/arch/evbsh3/conf/COMPUTEXEVB 1104 src/sys/arch/evbsh5/conf/CAYMAN64 1105 src/sys/arch/hp300/conf/GENERIC 1106 src/sys/arch/hp700/conf/GENERIC 1107 src/sys/arch/hpcarm/conf/JORNADA728 1108 src/sys/arch/hpcmips/conf/GENERIC 1109 src/sys/arch/hpcsh/conf/GENERIC 1110 src/sys/arch/hpcsh/conf/HPW650PA 1111 src/sys/arch/i386/conf/GENERIC 1112 src/sys/arch/i386/conf/GENERIC.MP 1113 src/sys/arch/i386/conf/XEN0 1114 src/sys/arch/i386/conf/XENU 1115 src/sys/arch/ibmnws/conf/GENERIC 1116 src/sys/arch/iyonix/conf/GENERIC 1117 src/sys/arch/luna68k/conf/GENERIC 1118 src/sys/arch/mac68k/conf/GENERIC 1119 src/sys/arch/macppc/conf/GENERIC 1120 src/sys/arch/macppc/conf/GENERIC.MP 1121 src/sys/arch/mipsco/conf/GENERIC 1122 src/sys/arch/mmeye/conf/GENERIC 1123 src/sys/arch/mvme68k/conf/GENERIC 1124 src/sys/arch/netwinder/conf/GENERIC 1125 src/sys/arch/news68k/conf/GENERIC 1126 src/sys/arch/newsmips/conf/GENERIC 1127 src/sys/arch/next68k/conf/GENERIC 1128 src/sys/arch/ofppc/conf/GENERIC 1129 src/sys/arch/pc532/conf/GENERIC 1130 src/sys/arch/pmax/conf/GENERIC 1131 src/sys/arch/prep/conf/GENERIC 1132 src/sys/arch/sandpoint/conf/GENERIC 1133 src/sys/arch/sbmips/conf/GENERIC 1134 src/sys/arch/sgimips/conf/GENERIC32_IP3x 1135 src/sys/arch/shark/conf/GENERIC 1136 src/sys/arch/sparc/conf/GENERIC 1137 src/sys/arch/sparc/conf/GENERIC.MP 1138 src/sys/arch/sparc64/conf/GENERIC 1139 src/sys/arch/sparc64/conf/GENERIC.MP 1140 src/sys/arch/sun2/conf/GENERIC 1141 src/sys/arch/sun3/conf/GENERIC 1142 src/sys/arch/vax/conf/GENERIC 1143 src/sys/arch/vax/conf/GENERIC.MP 1144 src/sys/arch/x68k/conf/GENERIC 1145 1146 src/sys/arch/playstation2/conf/GENERIC 1147 1148Branch: yamt-pdpolicy 1149Description: play with page replacement policy 1150 - separate page replacement policy from the rest of kernel 1151 - implement alternative replacement policy 1152 - related read-ahead adjustment?
