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: mycroft 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: Terminated 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 350 drivers are converted, the remaining 1/2 need more changes. 351 352 As of import this is snapshot of work in progress and so 353 may not compile; in particular the midi changes are very 354 much "in progress". The audio component has been tested 355 and verified to work with emuxki and auvia. There may 356 be a locking issue in the ac97 code at boot. 357 358 The are two locks per device instance, an ISR lock and 359 a character device lock. The ISR lock replaces calls to 360 splaudio()/splx(), and will be held across calls to device 361 methods which were called at splaudio() before (e.g. 362 trigger_output). The character device lock is held across 363 calls to nearly all of the methods, excluding some only 364 used for initialization, e.g. get_locks. This needs to be 365 documented at merge time. 366 367 To test on a multi way x86 system, search for "mpsafe" in 368 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job 369 that will acquire the ISR lock (depends on the hardware, but 370 "while true; do mixerctl -a > /dev/null; done" may suffice). 371 Play audio, run lockstat and verify that that there is 372 contention on the ISR lock. 373 374 Branch: ad-audiomp2 375 Description: Add MP locking to the audio drivers 376 Status: Terminated 377 Start Date: 7 December 2008 378 End Date: 19 November 2011 379 Base Tag: ad-audiomp2-base 380 Maintainer: Andrew Doran <ad (a] NetBSD.org> 381 Scope: kernel 382 Notes: Ressurect ad-audiomp, make the audio drivers MP safe. 383 384 Branch: ad-namecache 385 Description: Redo the namecache 386 Status: Active 387 Start Date: 8 January 2020 388 End Date: 389 Base Tag: ad-namecache-base 390 Maintainer: Andrew Doran <ad (a] NetBSD.org> 391 Scope: src/sys src/common 392 Notes: 1) Redo the namecache to focus on per-directory data 393 structures, removing the huge hashtable and nasty locking 394 scheme. 395 396 Initially this uses rbtrees (because that's what's there). 397 The intent is that ultimately some other data structure 398 will be used. 399 400 2) Experiment with having namei() traverse the cache and 401 avoid vnode locks except for the leaf in the totally 402 in-cache case. 403 404 Branch: agc-netpgp-standalone 405 Description: Remove dependency on openssl libraries in netpgp 406 Status: Active 407 Start Date: 5 May 2012 408 End Date: 409 Base Tag: agc-netpgp-standalone-base 410 Maintainer: Alistair Crooks <agc (a] NetBSD.org> 411 Scope: src/crypto/external/bsd/netpgp 412 Notes: This branch is used to develop the version of netpgp 413 which has its own version of bignum, ciphers, and signatures 414 libraries, so that it is able to operate without openssl 415 being in place. 416 417 Branch: agc-symver 418 Description: Add library symbol versioning information 419 Status: Active 420 Start Date: 24 March 2013 421 End Date: 422 Base Tag: agc-symver-base 423 Maintainer: Alistair Crooks <agc (a] NetBSD.org> 424 Scope: src 425 Notes: This branch is used to develop DSO symbol versioning, allowing 426 symbols to be added, modified and removed from shared libraries. 427 428 Branch: bjh21-hydra 429 Description: Simtec Hydra support and ARM SMP in general 430 Status: Dormant 431 Start Date: 18 Oct 2002 432 End Date: 433 Base Tag: bjh21-hydra-base 434 Maintainer: Ben Harris <bjh21 (a] NetBSD.org> 435 Scope: sys/arch/arm sys/arch/acorn32 436 Notes: This code was on a branch because it involves changes to 437 cpuswitch.S which would otherwise make merging the 438 nathanw_sa branch difficult. 439 440 Branch: bouyer-socketcan 441 Description: Implement a CAN socket layer compatible with linux SocketCAN 442 Status: Terminated 443 Start Date: Sun Jan 15 2017 444 End Date: May 27 2017 445 Base Tag: bouyer-socketcan-base 446 Maintainer: Manuel Bouyer <bouyer (a] NetBSD.org> 447 Scope: src/ 448 Notes: Some documentation on SocketCAN is there: 449 https://www.kernel.org/doc/Documentation/networking/can.txt 450 451 Branch: cherry-xenmp 452 Description: Port i386 and amd64 Xen kernels to run MP 453 Status: Terminated 454 Start Date: 1st June 2011 455 End Date: 13th January 2012 456 Base Tag: cherry-xenmp-base 457 Maintainer: Cherry G.

If you plan to 705 continue this branch, sys/netinet/in_pcb.h already contains 706 the proposed structure layout (which was roughly discussed 707 in the tech-net mailing list). 708 I also defined INP_*() macros to mimicate FreeBSD's inpcb 709 locking style, but currently they do nothing and are not 710 yet called at the correct places (needs discussion about 711 kernel fine-grained locking). 712 To continue this branch, one needs to read all the relevant 713 inpcb/in6pcb source files and change the function names, 714 structure names, structure fields according to the new 715 layout (in6pcb is gone). 716 Don't try to build a kernel from this branch because it won't 717 work. The missing pieces required to do a complete build 718 were not committed because they were incomplete and generated 719 panics. 720 You shouldn't need to worry about KAME syncs because 721 they did most of them by now. 722 After the work is done, you are required to test the branch 723 (before the merge to -current) with an interop IPv6 test. 724 More info at: http://www.tahi.org/ 725 726 Branch: thorpej-futex 727 Description: Overhaul of futex operations to fix thread priority issues 728 Status: Active 729 Start Date: Sun Nov 1 2020 730 End Date: 731 Base Tag: thorpej-futex-base 732 Maintainer: Jason Thorpe <thorpej (a] netbsd.org> 733 Scope: src/sys src/tests/lib/libc/sys 734 Note: Normal futex operataions pass the test suite, but there are 735 issues with Linux compatibility currently, that need to be 736 addressed before merging.

So it would be easier and cleaner 1732 to adjust that to deal w/ different block sizes. 1733 Also with UBC, all i/o is in terms of bytes at an offset 1734 with a certain length, so the exact block size isn't a big 1735 deal. 1736 1737 Any other wrstuden-devbsize tag may (and should) go away. 1738 1739 Branch: yamt-idlelwp 1740 Description: idle lwp, and some changes depending on it. 1741 1742 1. separate context switching and thread scheduling. 1743 (cf. gmcgarry_ctxsw) 1744 2. implement idle lwp. 1745 3. clean up related MD/MI interfaces. 1746 4. make scheduler(s) modular. 1747 1748 Status: Terminated; merged to -current 1749 Start Date: Fri Feb 17 2007 1750 End Date: Thu May 17 2007 1751 Base Tag: yamt-idlelwp-base8 1752 Maintainer: YAMAMOTO Takashi <yamt (a] NetBSD.org> 1753 Scope: src/sys (src/common is tagged but not branched) 1754 Notes: 1755 Status of ports: 1756 alpha [ Done, UP tested, MP not tested ] 1757 i386 [ Done, tested ] 1758 amd64 [ Done, tested ] 1759 mips [ Done, both MIPS1 and MIPS3 tested] 1760 sparc [ Done, UP tested, MP might have 1761 some problem after newlock2 merge ] 1762 sparc64 [ Done, tested ] 1763 arm [ Done, SA1 tested.

It is necessary 2117 for the newlock branch, making the scheduler SMP friendly, 2118 adding real-time scheduler extensions, and reducing the 2119 number of code paths for LWP and proc switching. 2120 2121 Branch: nick-hppapmap 2122 Description: Update of hppa pmap with OpenBSD code. 2123 Status: Terminated; merged to -current 2124 Start Date: 27 October 2008 2125 End Date: 30 April 2009 2126 Base Tag: nick-hppapmap-base3 2127 Maintainer: Nick Hudson <skrll (a] NetBSD.org> 2128 Scope: sys/ 2129 Notes: Port of the OpenBSD pmap including support for PA2.0 CPUs in 2130 32-bit mode. 2131 2132 Branch: thorpej-atomic 2133 Description: Implementation of an atomic memory operations API modeled 2134 after the one in Solaris 10. 2135 Status: Terminated; merged to -current 2136 Start Date: Apr 11 2007 2137 End Date: Nov 18 2007 2138 Base tag: thorpej-atomic-base 2139 Maintainer: Jason Thorpe <thorpej (a] netbsd.org> 2140 Scope: src/common 2141 src/sys 2142 Notes: Base atomic primitives need to be implemented for 2143 all of the supported architectures: 2144 2145 alpha DONE 2146 arm DONE 2147 hppa 2148 i386 DONE 2149 ia64 2150 m68k DONE (except for 68010) 2151 mips 2152 ns32k 2153 powerpc DONE except for membar_*() 2154 powerpc64 DONE except for membar_*() 2155 sh3 2156 sparc DONE except for membar_*() 2157 sparc64 DONE except for membar_*() 2158 vax 2159 x86_64 DONE 2160 2161 Tested: 2162 2163 alpha NO 2164 arm NO 2165 hppa NO 2166 i386 NO 2167 ia64 NO 2168 m68k NO 2169 mips NO 2170 ns32k NO 2171 powerpc NO 2172 powerpc64 NO 2173 sh3 NO 2174 sparc NO 2175 sparc64 NO 2176 vax NO 2177 x86_64 NO 2178 2179 TODO: 2180 2181 all - Need to replace mb_*() with membar_*(). 2182 2183 - Audit MUTEX_CAS() and RWLOCK_CAS() uses 2184 to see of membar_enter() is required here. 2185 2186 - Talk to ad@ -- figure out of non-atomic 2187 mutex / rwlock release is actually safe. 2188 2189 arm - Consider using a RAS technique like 2190 MIPS uses for _lock_cas() and the mutex 2191 stubs.
