#
# 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

#   Start Date:	  date first instantiated
#   End Date:	  date it was Terminated/made_Dormant, if any

Base Tag:	bjh21-hydra-base
Maintainer:	Ben Harris <bjh21 (a] NetBSD.org>
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.

Base Tag:	gehenna-devsw-base
Maintainer:	MAEKAWA Masahide <gehenna (a] NetBSD.org>

Start Date:	18 December 2002
End Date:
Base Tag:	gmcgarry_ctxsw_base
Maintainer:	Gregory McGarry <gmcgarry (a] NetBSD.org>
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.

Base Tag:	kqueue-base
Maintainer:	Jaromir Dolecek <jdolecek (a] NetBSD.org>
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

		bin/ps usr.bin/systat usr.bin/top usr.bin/w

		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

		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

		Please consult with the maintainer before committing

		Other tags starting with nathanw_sa reserved for

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 <sommerfeld (a] NetBSD.org>
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.

			  needs to be beat on a lot more to make

			  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 (a] 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 (a] NetBSD.org has
			  committed fixes to this code.  Awaiting
			  confirmation that it is working properly.

			* R5900 (cache_r5900) -- uch (a] 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().

Status:		Terminated
Start Date:	Aug or Sept 1999
End Date:	1 Apr 2000
Base tag:	wrstuden-devbsize-base
Maintainer:	Bill Studenmund <wrstuden (a] NetBSD.org>
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.
