BRANCHES revision 1.123

2#
3# This file contains a list of branches that exist in the NetBSD CVS
4# tree and their current state.
5#
6# This list is necessarily incomplete.
7# 
8# Within reason, developers may create branch and version tags at any
9# time for any purpose.  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.

211Branch:		bjh21-hydra

213Status:		Dormant
214Start Date:	18 Oct 2002
215End Date:
216Base Tag:	bjh21-hydra-base
217Maintainer:	Ben Harris <bjh21@NetBSD.org>
218Scope:		sys/arch/arm sys/arch/acorn32
219Notes:		This code was on a branch because it involves changes to
220		cpuswitch.S which would otherwise make merging the
221		nathanw_sa branch difficult.
222
223Branch:		gmcgarry_ctxsw
224Description:	Separate scheduler from context-switch code
225Status:		Dormant
226Start Date:	18 December 2002
227End Date:
228Base Tag:	gmcgarry_ctxsw_base
229Maintainer:	Gregory McGarry <gmcgarry@NetBSD.org>
230Scope:		kernel
231Notes:		Removing knowledge of the schedular and its run queues
232		from the machine-dependent context switch code is the
233		first step in cleaning up the scheduler.  It is necessary
234		for the newlock branch, making the scheduler SMP friendly,
235		adding real-time scheduler extensions, and reducing the
236		number of code paths for LWP and proc switching.

291Maintainer:	Jason R. Thorpe <thorpej@NetBSD.org>
292Scope:		Kernel
293Notes:		The goal is to replace the existing lockmgr() and
294		simple_lock() based locking mechanisms with the
295		primitives found in Solaris: mutexes and rwlocks.

302Base Tag:	newlock2-base
303Maintainer:	Andrew Doran <ad@NetBSD.org>
304Scope:		Kernel
305Notes:		As per the newlock branch, however given the amount of time
306		the original branch has lain dormant, a new one has been
307		created. Goals:
308		- Implement new locking primitives on most-used ports.
309		- Minor locking improvements.
310		- Remove spinlockmgr().

859Maintainer:	Bill Studenmund <wrstuden@NetBSD.org>
860Scope:		kernel
861Notes:		No longer active due to lack of time, and introduction
862		of UBC. In terms of UBC, the primary cache for
863		file data is the VM cache, which needs to operate
864		in terms of VM pages. As no existing device has native
865		pages the same size as our VM pages, there already is
866		a mapping going on between the VM system and the
867		underlying blocks. So it would be easier and cleaner
868		to adjust that to deal w/ different block sizes.
869		Also with UBC, all i/o is in terms of bytes at an offset
870		with a certain length, so the exact block size isn't a big
871		deal.
872
873		Any other wrstuden-devbsize tag may (and should) go away.
