# $NetBSD: BRANCHES,v 1.14 2004/11/15 10:31:50 rtr 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.

End Date:
Base Tag: bjh21-hydra-base
Maintainer: Ben Harris <bjh21@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.

Description: auto-generation of devsw table
Status: Terminated
Start Date: 16 May 2002
End Date: 6 Sep 2002
Base Tag: gehenna-devsw-base
Maintainer: MAEKAWA Masahide <gehenna@NetBSD.org>
Scope: syssrc
Notes: The goal is to get rid of the existing device switch tables in
port-dependent conf.c and to generate them dynamically by
config(8).
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 <gmcgarry@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@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
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.

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

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.

as the data structures required for unremove are in and tested.
Branch: pkgviews
Description: package views, enabling multiple conflicting packages to co-exist

Start Date: 22 July 2002
End Date:
Base Tag: pkgviews
Maintainer: Alistair Crooks <agc@NetBSD.org>
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 <sommerfeld@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.

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: 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 <wrstuden@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.
