BRANCHES revision 1.248
1#	$NetBSD: BRANCHES,v 1.248 2008/03/24 12:34:51 yamt Exp $
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

35# There are four sections to this file:
36#   Release branches
37#   Individual developers' branches (Active/Dormant)

211Branch:		ad-audiomp
212Description:	Add MP locking to the audio drivers
213Status:		Active
214Start Date:	28 February 2007
215End Date:
216Base Tag:	ad-audiomp-base
217Maintainer:	Andrew Doran <ad@NetBSD.org>
218Scope:		kernel
219Notes:		Making the audio drivers MP safe is necessary before efforts
220		can be made to make the VM system MP safe. About 1/2 of the
221		drivers are converted, the remaining 1/2 need more changes.
222
223		As of import this is snapshot of work in progress and so
224		may not compile; in particular the midi changes are very
225		much "in progress". The audio component has been tested
226		and verified to work with emuxki and auvia. There may
227		be a locking issue in the ac97 code at boot.
228
229		The are two locks per device instance, an ISR lock and
230		a character device lock. The ISR lock replaces calls to
231		splaudio()/splx(), and will be held across calls to device
232		methods which were called at splaudio() before (e.g.
233		trigger_output). The character device lock is held across
234		calls to nearly all of the methods, excluding some only
235		used for initialization, e.g. get_locks. This needs to be
236		documented at merge time.
237
238		To test on a multi way x86 system, search for "mpsafe" in
239		x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job
240		that will acquire the ISR lock (depends on the hardware, but
241		"while true; do mixerctl -a > /dev/null; done" may suffice).
242		Play audio, run lockstat and verify that that there is
243		contention on the ISR lock.

245Branch:		bjh21-hydra
246Description:	Simtec Hydra support and ARM SMP in general
247Status:		Dormant

250Base Tag:	bjh21-hydra-base
251Maintainer:	Ben Harris <bjh21@NetBSD.org>
252Scope:		sys/arch/arm sys/arch/acorn32
253Notes:		This code was on a branch because it involves changes to
254		cpuswitch.S which would otherwise make merging the
255		nathanw_sa branch difficult.
256
257Branch:		chris-arm-intr-rework

279Branch:		gmcgarry_ctxsw
280Description:	Separate scheduler from context-switch code
281Status:		Dormant

283End Date:
284Base Tag:	gmcgarry_ctxsw_base
285Maintainer:	Gregory McGarry <gmcgarry@NetBSD.org>
286Scope:		kernel
287Notes:		Removing knowledge of the scheduler and its run queues
288		from the machine-dependent context switch code is the
289		first step in cleaning up the scheduler.  It is necessary
290		for the newlock branch, making the scheduler SMP friendly,
291		adding real-time scheduler extensions, and reducing the
292		number of code paths for LWP and proc switching.

451End Date:	
452Base Tag:	rpaulo-netinet-merge-pcb-base
453Maintainer:	Rui Paulo <rpaulo@NetBSD.org>
454Scope:		src/sys
455Notes:		No longer active due to the lack of time. If you plan to
456		continue this branch, sys/netinet/in_pcb.h already contains
457		the proposed structure layout (which was roughly discussed
458		in the tech-net mailing list).
459		I also defined INP_*() macros to mimicate FreeBSD's inpcb
460		locking style, but currently they do nothing and are not
461		yet called at the correct places (needs discussion about
462		kernel fine-grained locking).
463		To continue this branch, one needs to read all the relevant
464		inpcb/in6pcb source files and change the function names,
465		structure names, structure fields according to the new
466		layout (in6pcb is gone).
467		Don't try to build a kernel from this branch because it won't
468		work. The missing pieces required to do a complete build
469		were not committed because they were incomplete and generated
470		panics.
471		You shouldn't need to worry about KAME syncs because
472		they did most of them by now.
473		After the work is done, you are required to test the branch
474		(before the merge to -current) with an interop IPv6 test.

500Scope:		src, though all the interesting stuff is in the kernel
501		or lib/libpthread or maybe gdb.
502Notes:		This branch is based off of the netbsd-4 branch!
503		This branch is intended to stage improvements for the
504		Scheduler Activations system for NetBSD 4. Improvements
505		include not allocating memory while preparing to tsleep(),
506		reducing inappropriate upcall delivery (hopefully also
507		eliminating the need to mlock stacks), and being
508		able to pthread_kill() running threads.

527Branch:		reinoud-bufcleanup
528Description:	implement and evaluate struct buf usage cleanup strategies.
529		Ideas currently in mind (preference for b):
530		a)
531			1. use of bio_ops per buffer.
532			2. allow chaining/overloading of functions in bio_ops
533			   and provide some private context.
534			3. extend the bio_ops with commonly used functionality
535			   like pending action counting, custom context passing,
536			   last minute processing of buffer data, buffer cache
537			   etc.
538			4. investigate the use of the kcont()
539			   continuation-passing framework for async io
540			   completion notification for bufs
541			...

1225Base tag:	wrstuden-devbsize-base
1226Maintainer:	Bill Studenmund <wrstuden@NetBSD.org>
1227Scope:		kernel
1228Notes:		No longer active due to lack of time, and introduction
1229		of UBC. In terms of UBC, the primary cache for
1230		file data is the VM cache, which needs to operate
1231		in terms of VM pages. As no existing device has native
1232		pages the same size as our VM pages, there already is
1233		a mapping going on between the VM system and the
1234		underlying blocks. So it would be easier and cleaner
1235		to adjust that to deal w/ different block sizes.
1236		Also with UBC, all i/o is in terms of bytes at an offset
1237		with a certain length, so the exact block size isn't a big
1238		deal.
1239
1240		Any other wrstuden-devbsize tag may (and should) go away.

1276		How to adapt a port?
1277
1278		- unify cpu_switch, cpu_exit, cpu_switchto into
1279		  a single cpu_switchto.  see cpu_switchto.9.
1280
1281		- implement cpu_idle.  see cpu_idle.9.
1282
1283		- add a flag argument to cpu_need_resched.
1284		  handle RESCHED_IMMED flag, which means "cause a preemption
1285		  as soon as possible."  eg. in the case of MULTIPROCESSOR,
1286		  send an IPI to the target cpu.
1287
1288		- "curlwp == NULL" is not a valid check for idle state anymore.
1289		  use "(curlwp->l_flag & LW_IDLE) != 0" instead.  curlwp is
1290		  almost always non-NULL, with exceptions like early on boot.
1291
1292		- remove idle pcbs.
1293
1294		- (if MULTIPROCESSOR) tweak processor trampoline code.
1295
1296		- (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1297		  secondary processors.
1298
1299		- (if schedhz!=0) call schedclock regardless of the value of
1300		  curlwp.
1301
1302		- of course, update MD users of scheduler/switching API.
