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: Terminated 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 232 drivers are converted, the remaining 1/2 need more changes. 233 234 As of import this is snapshot of work in progress and so 235 may not compile; in particular the midi changes are very 236 much "in progress". The audio component has been tested 237 and verified to work with emuxki and auvia. There may 238 be a locking issue in the ac97 code at boot. 239 240 The are two locks per device instance, an ISR lock and 241 a character device lock. The ISR lock replaces calls to 242 splaudio()/splx(), and will be held across calls to device 243 methods which were called at splaudio() before (e.g. 244 trigger_output). The character device lock is held across 245 calls to nearly all of the methods, excluding some only 246 used for initialization, e.g. get_locks. This needs to be 247 documented at merge time. 248 249 To test on a multi way x86 system, search for "mpsafe" in 250 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 251 that will acquire the ISR lock (depends on the hardware, but 252 "while true; do mixerctl -a > /dev/null; done" may suffice). 253 Play audio, run lockstat and verify that that there is 254 contention on the ISR lock. 255 256Branch: ad-audiomp2 257Description: Add MP locking to the audio drivers 258Status: Active 259Start Date: 7 December 2008 260End Date: 261Base Tag: ad-audiomp2-base 262Maintainer: Andrew Doran <ad@NetBSD.org> 263Scope: kernel 264Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 265 266Branch: bjh21-hydra 267Description: Simtec Hydra support and ARM SMP in general 268Status: Dormant 269Start Date: 18 Oct 2002 270End Date: 271Base Tag: bjh21-hydra-base 272Maintainer: Ben Harris <bjh21@NetBSD.org> 273Scope: sys/arch/arm sys/arch/acorn32 274Notes: This code was on a branch because it involves changes to 275 cpuswitch.S which would otherwise make merging the 276 nathanw_sa branch difficult. 277 278Branch: chris-arm-intr-rework 279Description: Rework arm interrupt handling code 280Status: Active 281Start Date: 11 Aug 2007 282End Date: 283Base Tag: chris-arm-intr-rework-base 284Maintainer: Chris Gilbert <chris@NetBSD.org> 285Scope: sys/arch/arm sys/arch/cats (other arm archs to follow) 286Notes: Rework arm interrupt code to provide a shared set of interrupt 287 routines, and allow improvements to be shared across all arm 288 based hardware. 289 290Branch: cube-autoconf 291Description: Renovate autoconf(9) API 292Status: Active 293Start Date: 11 Dec 2007 294End Date: 295Base Tag: cube-autoconf-base 296Maintainer: Quentin Garnier <cube@NetBSD.org> 297Scope: kernel usr.bin/config (and some other userland bits) 298Notes: Address a number of issues the current autoconf(9) API has. 299 300Branch: gmcgarry_ctxsw 301Description: Separate scheduler from context-switch code 302Status: Dormant 303Start Date: 18 December 2002 304End Date: 305Base Tag: gmcgarry_ctxsw_base 306Maintainer: Gregory McGarry <gmcgarry@NetBSD.org> 307Scope: kernel 308Notes: Removing knowledge of the scheduler and its run queues 309 from the machine-dependent context switch code is the 310 first step in cleaning up the scheduler. It is necessary 311 for the newlock branch, making the scheduler SMP friendly, 312 adding real-time scheduler extensions, and reducing the 313 number of code paths for LWP and proc switching. 314 315Branch: gmcgarry_ucred 316Description: Integrate and encapsulate user credentials 317Status: Dormant 318Start Date: 18 December 2002 319End Date: 320Base Tag: gmcgarry_ucred_base 321Maintainer: Gregory McGarry <gmcgarry@NetBSD.org> 322Scope: kernel 323Notes: merge pcred and ucred and poolify 324 325Branch: hpcarm-cleanup 326Description: Fix build problems for hpcarm 327Status: Active 328Start Date: 31 July 2007 329End Date: 330Base Tag: hpcarm-cleanup-base 331Maintainer: Robert Swindells <rjs@NetBSD.org> 332Scope: kernel 333Notes: Modify SA11x0 interrupt code to match PXA2x0 equivalent. 334 335Branch: itohy-usb1 336Description: USB stack overhaul, mostly DMA related 337Status: Active 338Start Date: 22 May 2007 339End Date: 340Base Tag: itohy-usb1-base 341Maintainer: ITOH Yasufumi <itohy@NetBSD.org> 342Scope: kernel 343Notes: To check out the kernel source tree, 344 1. check out checkout script 345 cvs checkout -ritohy-usb1 src/sys/dev/usb/filelist 346 2. update files in the branch 347 sh -e src/sys/dev/usb/filelist 348 349Branch: jym-xensuspend 350Description: Implement xm save/restore/migrate for NetBSD domU 351Status: Active 352Start Date: 2009-02-08 353End Date: 354Base Tag: jym-xensuspend-base 355Maintainer: Jean-Yves Migeon <jym@NetBSD.org> 356Scope: kernel 357Notes: This branch contains the code required to support the Xen 358 save/restore/migrate facilities.

If you plan to 489 continue this branch, sys/netinet/in_pcb.h already contains 490 the proposed structure layout (which was roughly discussed 491 in the tech-net mailing list). 492 I also defined INP_*() macros to mimicate FreeBSD's inpcb 493 locking style, but currently they do nothing and are not 494 yet called at the correct places (needs discussion about 495 kernel fine-grained locking). 496 To continue this branch, one needs to read all the relevant 497 inpcb/in6pcb source files and change the function names, 498 structure names, structure fields according to the new 499 layout (in6pcb is gone). 500 Don't try to build a kernel from this branch because it won't 501 work. The missing pieces required to do a complete build 502 were not committed because they were incomplete and generated 503 panics. 504 You shouldn't need to worry about KAME syncs because 505 they did most of them by now. 506 After the work is done, you are required to test the branch 507 (before the merge to -current) with an interop IPv6 test. 508 More info at: http://www.tahi.org/ 509 510Branch: rtr-xorg-branch 511Description: xorg & static build alterations to src/x11 512Status: Active 513Start Date: Nov 15 2004 514End Date: 515Base tag: rtr-xorg-branch-base 516Maintainer: Tyler R.

Improvements 538 include not allocating memory while preparing to tsleep(), 539 reducing inappropriate upcall delivery (hopefully also 540 eliminating the need to mlock stacks), and being 541 able to pthread_kill() running threads. At this date, 542 most goals have been achieved.

In terms of UBC, the primary cache for 1338 file data is the VM cache, which needs to operate 1339 in terms of VM pages. As no existing device has native 1340 pages the same size as our VM pages, there already is 1341 a mapping going on between the VM system and the 1342 underlying blocks. So it would be easier and cleaner 1343 to adjust that to deal w/ different block sizes. 1344 Also with UBC, all i/o is in terms of bytes at an offset 1345 with a certain length, so the exact block size isn't a big 1346 deal. 1347 1348 Any other wrstuden-devbsize tag may (and should) go away. 1349 1350Branch: yamt-idlelwp 1351Description: idle lwp, and some changes depending on it. 1352 1353 1. separate context switching and thread scheduling. 1354 (cf. gmcgarry_ctxsw) 1355 2. implement idle lwp. 1356 3. clean up related MD/MI interfaces. 1357 4. make scheduler(s) modular. 1358 1359Status: Terminated; merged to -current 1360Start Date: Fri Feb 17 2007 1361End Date: Thu May 17 2007 1362Base Tag: yamt-idlelwp-base8 1363Maintainer: YAMAMOTO Takashi <yamt@NetBSD.org> 1364Scope: src/sys (src/common is tagged but not branched) 1365Notes: 1366 Status of ports: 1367 alpha [ Done, UP tested, MP not tested ] 1368 i386 [ Done, tested ] 1369 amd64 [ Done, tested ] 1370 mips [ Done, both MIPS1 and MIPS3 tested] 1371 sparc [ Done, UP tested, MP might have 1372 some problem after newlock2 merge ] 1373 sparc64 [ Done, tested ] 1374 arm [ Done, SA1 tested.
