# $NetBSD: BRANCHES,v 1.17 2005/01/16 14:44:22 kent Exp $ # # This file contains a list of branches that exist in the NetBSD CVS # tree and their current state. # # This list is necessarily incomplete. # # Within reason, developers may create branch and version tags at any # time for any purpose. To avoid name collisions, private tags should # have names which begin with the developer's NetBSD login name # followed by a - or _ character (e.g., thorpej_scsipi, # thorpej-signal) # # Any branch or version tag not listed here should be assumed to be # private to the developer who created it. It is inappropriate for # anyone other than that developer to commit, move tags, or otherwise # modify the contents of the branch. # # Please update this file when a new branch is ready for consumption # by folks other than the maintainer, or when the use or status of an # existing branch changes significantly. # # Format: # Branch: name of branch # Description: Purpose and intention of the branch # Status: Active/Terminated/Dormant # Start Date: date first instantiated # End Date: date it was Terminated/made_Dormant, if any # Base Tag: netbsd-1-5-base, etc. # Maintainer: Somebody to blame. # Scope: Portion of the tree covered. # Notes: Various other info, perhaps explanation of special tags, # who-may-commit policies, etc. # Release branches: Branch: comdex-fall-1999 Description: Special release branch for pre-1.5 release at Fall 1999 COMDEX.

(src + xsrc) Notes: Commits restricted to Release Engineering. # Individual developers' branches: Branch: bjh21-hydra Description: Simtec Hydra support and ARM SMP in general Status: Active Start Date: 18 Oct 2002 End Date: Base Tag: bjh21-hydra-base Maintainer: Ben Harris Scope: sys/arch/arm sys/arch/acorn32 Notes: This code is on a branch because it involves changes to cpuswitch.S which would otherwise make merging the nathanw_sa branch difficult. This branch is expected to be merged to the trunk shortly after nathanw_sa. Branch: bouyer-scsipi Description: Integration of atapi support Status: Terminated Start Date: End Date: Base Tag: Maintainer: Manuel Bouyer Scope: kernel Notes: Superseded by thorpej_scsipi Branch: chs-ubc Description: ? Unified Buffer Cache Status: ? Start Date: End Date: Base Tag: chs-ubc-base Maintainer: Chuck Silvers Scope: kernel Notes: Branch: chs-ubc2 Description: ? Unified Buffer Cache Status: ?

Branch: gmcgarry_ctxsw Description: Separate scheduler from context-switch code Status: Active Start Date: 18 December 2002 End Date: Base Tag: gmcgarry_ctxsw_base Maintainer: Gregory McGarry Scope: kernel Notes: Removing knowledge of the schedular and its run queues from the machine-dependent context switch code is the first step in cleaning up the scheduler. It is necessary for the newlock branch, making the scheduler SMP friendly, adding real-time scheduler extensions, and reducing the number of code paths for LWP and proc switching. Branch: gmcgarry_ucred Description: Integrate and encapsulate user credentials Status: Active Start Date: 18 December 2002 End Date: Base Tag: gmcgarry_ucred_base Maintainer: Gregory McGarry Scope: kernel Notes: merge pcred and ucred and poolify Branch: is-newarp Description: ?

Start Date: End Date: Base Tag: is-newarp-base Maintainer: Ignatios Souvatzis Scope: kernel Notes: Branch: kame Description: KAME Project Status: Dormant Start Date: 28 Jun 1999 End Date: Base Tag: Maintainer: Jun-ichiro itojun Hagino Scope: kernel Notes: http://www.kame.net Used for "reference" purposes for early part of KAME integration effort. The branch is not actively used, as I (itojun) use patch(1) and diff(1) for the KAME syncs. Branch: kenh-if-detach Description: Interface detach support. Status: ? Start Date: End Date: Base Tag: kenh-if-detach-base Maintainer: Ken Hornstein Scope: kernel Notes: Branch: kent-audio1 Description: Audio converter pipeline Status: Active Start Date: Tue Dec 7 2004 End Date: Tue Jan 11 2005 Base Tag: kent-audio1-base Maintainer: TAMURA Kent Scope: kernel (audio device drivers) Notes: http://mail-index.netbsd.org/tech-kern/2004/12/03/0007.html Please consult with the maintainer before committing to this branch. Branch: kent-audio2 Description: In-kernel audio mixer Status: Active Start Date: Sun Jan 16 2005 End Date: Base Tag: kent-audio2-base Maintainer: TAMURA Kent Scope: kernel (audio device drivers) Notes: http://mail-index.netbsd.org/tech-kern/2004/12/03/0007.html Please consult with the maintainer before committing to this branch. Branch: kqueue Description: kqueue kernel event notification mechanism (from FreeBSD) Status: Terminated; merged to -current Start Date: Tue Jul 10 23:08:38 EST 2001 End Date: Tue Oct 24 09:14:14 GMT 2002 Base Tag: kqueue-base Maintainer: Jaromir Dolecek Scope: kernel, libc/sys, share/man/man9, usr.bin/fstat Notes: Integration of FreeBSD's kqueue(2) mechanism, with various local internal changes to better suit NetBSD, and enhancements such as looking up filters by name or number, and dynamic registration of "user" filters. The work is complete as is, but is awaiting more feedback from various kernel gurus before going mainline. Branch: ktrace-lwp Description: ktrace support for lwp ids. Status: Active Start Date: Wed Jul 2 15:27:30 UTC 2003 End Date: Base Tag: ktrace-lwp-base Maintainer: Darren Reed Scope: sys Notes: Branch: marc-pcmcia Description: PCMCIA support Status: Terminated; merged to -current Start Date: End Date: Base Tag: marc-pcmcia-base, marc-pcmcia-bp Maintainer: Marc Horowitz Scope: kernel Notes: Branch: minoura_x68k_bus_h Description: bus_space(9) and bus_dma(9) implementation for x68k Status: Terminated; merged to -current Start Date: 23 Dec 1998 End Date: 16 Mar 1999 Base Tag: minoura_x68k_bus_h-base Maintainer: Minoura Makoto Scope: sys/arch/x68k Notes: Branch: minoura-xpg4dl Description: Citrus Project locale subsystem Status: Terminated; (partly) merged to -current Start Date: 28 March 2000 End Date: Base Tag: minoura-xpg4dl-base Maintainer: Minoura Makoto Scope: basesrc, syssrc, sharesrc Notes: Citrus Project is developing dynamically-loadable, codeset- independent locale subsystem. Part of the implementation (LC_CTYPE) called XPG4DL is now integrated to -current. Branch: mrg-vm-swap Description: ? Status: ? Start Date: End Date: Base Tag: ? Maintainer: Matthew R. Green Scope: kernel Notes: Branch: nathanw_sa Description: Scheduler activations Status: Active Start Date: 5 March 2001 End Date: 18 January 2003 Base Tag: nathanw_sa_base Maintainer: Nathan Williams Scope: kernel, libc, libkvm, libpthread, libpthread_dbg, include, bin/ps usr.bin/systat usr.bin/top usr.bin/w gnu/dist/toolchain/gdb gnu/usr.bin/gdb Notes: The idea of scheduler activations is described in the classic paper by Anderson et al., in ACM Transactions a on Computer Systems volume 10 issue 1 (1992),which can be found at http://www.acm.org/pubs/citations/journals/tocs/1992-10-1/p53-anderson/ Many ideas in the implementation are based on the implementation of scheduler activations added to Mach 3.0 and described by Davis et al. in the University of Washington CS tech report 92-08-93, which can be found at ftp://ftp.cs.washington.edu/tr/1992/08/UW-CSE-92-08-03.PS.Z My USENIX paper on the subject can be found at http://web.mit.edu/nathanw/www/usenix/ Please consult with the maintainer before committing to this branch. Other tags starting with nathanw_sa reserved for branch management and are not guaranteed to be stable. Trunk tagged with "nathanw_sa_before_merge" prior to merging branch down to trunk. Branch tagged with "nathanw_sa_end" to indicate the ending revision of the branch. Branch: newlock Description: New locking primitives, based on Solaris's Status: Active Start Date: March 9, 2002 End Date: Base Tag: newlock-base Maintainer: Jason R. Thorpe Scope: Kernel Notes: The goal is to replace the existing lockmgr() and simple_lock() based locking mechanisms with the primitives found in Solaris: mutexes and rwlocks. Branch: perseant-lfsv2 Description: LFS incompatible on-disk data structure changes Status: Terminated Start Date: 27 June 2001 End Date: 16 July 2001 Base Tag: perseant-lfsv2-base Maintainer: Konrad Schroder Scope: basesrc/{sbin/*lfs,libexec/lfs_cleanerd,usr.sbin/dumplfs}, syssrc/sys/ufs Notes: This branch should be short-lived, I expect to merge as soon as the data structures required for unremove are in and tested. Branch: pkgviews Description: package views, enabling multiple conflicting packages to co-exist Status: Active Start Date: 22 July 2002 End Date: Base Tag: pkgviews Maintainer: Alistair Crooks Scope: pkgsrc, basesrc/usr.sbin/pkg_install Notes: A more flexible infrastructure for third-party packages by allowing multiple conflicting packages and versions to co-exist within the same tree Branch: sommerfeld_i386mp_1 Description: Multiprocessor support for i386 using Intel MP BIOS. Status: Terminated; merged to -current Start Date: 21 Feb 2000 End Date: 01 Oct 2002 Base Tag: sommerfeld_i386mpbase_1 Maintainer: Bill Sommerfeld Scope: sys/arch/i386 Notes: Code committed to the branch has booted to multiuser on at least one system. Not guaranteed to compile against mainline since -current may have changed incompatibly with the last branch update; use "cvs update -D" to roll-back the rest of the tree to match. Please get explicit permission from the maintainer before each commit, or your changes will be backed out. Other tags starting with sommerfeld_ are private to the developer and are guaranteed to be unstable. Only the maintainer should move tags. Note that this branch uses a DIFFERENT scheme for synching with the mainline. the maintainer uses some private scripts for keeping them in synch; if you make commits to the branch to "resynchronize" things, you'll probably do it wrong; instead, ask the maintainer to resynchronize things. See sys/arch/i386/TODO on the branch for a list of known issues with the branch. Branch: thorpej-devvp Description: replace dev_t with struct vnode * in devsw entry points Status: Active Start Date: Sep 6 2001 End Date: Base Tag: thorpej-devvp-base Maintainer: Jason Thorpe Scope: syssrc Notes: Kernels built from this branch are not expected to function correctly at this time. Ports known to compile on this branch: alpha i386 Branch: thorpej-mips-cache Description: overhaul MIPS cache support code Status: Terminated; merged to -current Start Date: Oct 23 2001 End Date: Nov 14 2001 Base Tag: thorpej-mips-cache-base Scope: syssrc Notes: This branch needs more debugging, testing, and more ports need to be converted to the new world order. The following processors have had cache ops written: * R2000/R3000 (cache_r3k) -- light testing, needs to be beat on a lot more to make sure it's working. * R4000/R4400 (cache_r4k) -- mhitch@NetBSD.org tracked down a bug, which has been fixed. Confirmed working on R4000-with-L2. Confirmed working on R4400-no-L2 and R4400-with-L2. * R4600/R5000 (cache_r5k) -- shin@NetBSD.org has committed fixes to this code. Confirmed working on R4600 v2 (SGI IP-22 with no SysAD L2 cache). Confirmed working on RM5260 (Algorithmics P-5064). * TX39 (cache_tx39) -- uch@NetBSD.org has committed fixes to this code. Awaiting confirmation that it is working properly. * R5900 (cache_r5900) -- uch@NetBSD.org has written this code and tested it on a PlayStation 2. The following ports have been updated to compile (and use optimized-for-processor bus_dma routines). Those that have been tested and work are marked with [WORKING]. * algor [WORKING] * arc [WORKING] * pmax [WORKING] * playstation2 [WORKING] Needs optimized bus_dmamap_sync(). * hpcmips [need verification that this is working] Needs optimized bus_dmamap_sync(). * sgimips [WORKING] Needs optimized bus_dmamap_sync(). * cobalt [need testing] * mipsco [need testing] * newsmips [need testing] Branch: thorpej_scsipi Description: SCSI/ATAPI midlayer rewrite. Status: Terminated; merged to -current Start Date: End Date: Apr 25 2001 Base Tag: thorpej_scsipi_base, thorpej_scsipi_nbase Maintainer: Manuel Bouyer , Jason Thorpe Scope: syssrc Notes: When a change from -current is pulled up please move the thorpej_scsipi_base tag to the revision you're syncing with. thorpej_scsipi_nbase is private to maintainer (only used when syncing the whole branch with HEAD). Just before the merge, syssrc has been tagged with thorpej_scsipi_beforemerge Branch: thorpej-signal Description: ? Status: ? Start Date: End Date: Base Tag: thorpej-signal-base Maintainer: Jason Thorpe Scope: kernel Notes: Branch: thorpej-setroot Description: ? Status: Terminated; merged to -current Start Date: End Date: Base Tag: Maintainer: Jason Thorpe Scope: kernel Notes: Branch: wrstuden-devbsize Description: Modify buffer cache to deal with different devices having different block sizes. Also DEV_BSIZE would go away. Status: Terminated Start Date: Aug or Sept 1999 End Date: 1 Apr 2000 Base tag: wrstuden-devbsize-base Maintainer: Bill Studenmund Scope: kernel Notes: No longer active due to lack of time, and introduction of UBC. In terms of UBC, the primary cache for file data is the VM cache, which needs to operate in terms of VM pages. As no existing device has native pages the same size as our VM pages, there already is a mapping going on between the VM system and the underlying blocks. So it would be easier and cleaner to adjust that to deal w/ different block sizes. Also with UBC, all i/o is in terms of bytes at an offset with a certain length, so the exact block size isn't a big deal. Any other wrstuden-devbsize tag may (and should) go away. Branch: rtr-xorg-branch Description: xorg & static build alterations to src/x11 Status: Active Start Date: Nov 15 2004 End Date: Base tag: rtr-xorg-branch-base Maintainer: Tyler R.
