BRANCHES revision 1.216

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.

211Branch:		ad-audiomp
212Description:	Add MP locking to the audio drivers
213Status:		Active
214Start Date:	28 Febuary 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 initializtion, 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

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

275		routines, and allow improvements to be shared across all arm
276		based hardware.
277
278Branch:		gmcgarry_ctxsw
279Description:	Separate scheduler from context-switch code
280Status:		Dormant
281Start Date:	18 December 2002
282End Date:
283Base Tag:	gmcgarry_ctxsw_base
284Maintainer:	Gregory McGarry <gmcgarry@NetBSD.org>
285Scope:		kernel
286Notes:		Removing knowledge of the schedular and its run queues
287		from the machine-dependent context switch code is the
288		first step in cleaning up the scheduler.  It is necessary
289		for the newlock branch, making the scheduler SMP friendly,
290		adding real-time scheduler extensions, and reducing the
291		number of code paths for LWP and proc switching.

452Scope:		src/sys/arch
453Notes:		This branch is for a general cleanup of all OEA-based PowerPC
454		ports. OEA (Operating Environment Architecture) PowerPC refers
455		to the 601, 603, 604, and similar chips.  Specifically, not the
456		403/401 and other embedded chips. The general concept is to get
457		them all compiling, and sharing as much code as possible.  All
458		developers are welcome to commit to this branch.

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468Notes:		No longer active due to the lack of time.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

515Notes:		This branch is based off of the netbsd-4 branch!
516		This branch is intended to stage improvements for the
517		Scheduler Activations system for NetBSD 4. Improvements
518		include not allocating memory while preparing to tsleep(),
519		reducing inappropriate upcall delivery (hopefully also
520		eliminating the need to mlock stacks), and being
521		able to pthread_kill() running threads.

552		Remaining MD work to do:
553
554		- Defer x86 npxsave interrupts to an process context (do
555		  aston() and handle from trap.c).
556
557		- Port other architectures.
558
559		Remaining MI work to do:
560
561		- Clean up vfs_busy/vfs_unbusy and mount/dounmount semantics
562		  so that lockmgr is not being used any more. Reference
563		  counting on struct mount is probably the best solution.
564
565		- Check + document locking around fields in struct mount.
566
567		- Check file systems that traverse mountpoint vnode lists.
568		  They need to use marker vnodes. Most already done.
569
570		- Re-write the itimer code to be MP safe and work in the
571		  presence of threaded soft interrupts.
572
573		- Check aliased vnode handling. There may be problems.
574
575		Remaining problems:
576
577		- tmpfs_rmdir occasionally leaks tmpfs_nodes. This could be
578		  an old problem but either way it needs to be fixed.
579
580		- UVM_FLAG_TRYLOCK is not sufficient in uvm_km.c because
581		  allocations will fail too often. It's needed for !kmem_map
582		  because sometimes allocations are made by threads that
583		  hold the map locked, which could cause other threads to
584		  wait long term even if they are trying to make a NOWAIT
585		  allocation.
586
587		- ffs+snapshots needs testing.
588
589		- LFS port has been fudged and it's probably borked.
590
591		- ext2fs panic on unmount.

593Branch:		yamt-lazymbuf
594Description:	implement and evaluate lazy mapping of mbuf external data pages
595		also, change the way to share mbuf external storage.
596		it's intended as the first step of larger changes.
597			1. support operations (esp. bus_dma load) on
598			   unmapped mbuf.
599			2. unify mbuf and buf.
600			   (or, at least some parts of them)
601			3. then it should be trivial to implement
602			   i/o coalescing, etc.

615Branch:		reinoud-bufcleanup
616Description:	implement and evaluate struct buf usage cleanup strategies.
617		Ideas currently in mind (preference for b):
618		a)
619			1. use of bio_ops per buffer.
620			2. allow chaining/overloading of functions in bio_ops
621			   and provide some private context.
622			3. extend the bio_ops with commenly used functionality
623			   like pending action counting, custom context passing,
624			   last minute processing of buffer data, buffer cache
625			   etc.
626			4. investigate the use of the kcont()
627			   continuation-passing framework for async io
628			   completion notification for bufs
629			...
630		b)
631			1. all sequencing use of B_CALL replaced by
632			   device-threads, if possible generic code around BUFQ
633			2. possibly use kcont() for async IO finished signalling
634			3. counter of pending and queued actions requestable
635			   by IOCTL interface?
636			4. implement `last minute buffer fixup' calls and maybe
637			   even finished I/O calls as vnode operations
638			...

1182Scope:		kernel
1183Notes:		No longer active due to lack of time, and introduction
1184		of UBC. In terms of UBC, the primary cache for
1185		file data is the VM cache, which needs to operate
1186		in terms of VM pages. As no existing device has native
1187		pages the same size as our VM pages, there already is
1188		a mapping going on between the VM system and the
1189		underlying blocks. So it would be easier and cleaner
1190		to adjust that to deal w/ different block sizes.
1191		Also with UBC, all i/o is in terms of bytes at an offset
1192		with a certain length, so the exact block size isn't a big
1193		deal.
1194
1195		Any other wrstuden-devbsize tag may (and should) go away.

1231		How to adapt a port?
1232
1233		- unify cpu_switch, cpu_exit, cpu_switchto into
1234		  a single cpu_switchto.  see cpu_switchto.9.
1235
1236		- implement cpu_idle.  see cpu_idle.9.
1237
1238		- add a flag argument to cpu_need_resched.
1239		  handle RESCHED_IMMED flag, which means "cause a preemption
1240		  as soon as possible."  eg. in the case of MULTIPROCESSOR,
1241		  send an IPI to the target cpu.
1242
1243		- "curlwp == NULL" is not a valid check for idle state anymore.
1244		  use "(curlwp->l_flag & LW_IDLE) != 0" instead.  curlwp is
1245		  almost always non-NULL, with exceptions like early on boot.
1246
1247		- remove idle pcbs.
1248
1249		- (if MULTIPROCESSOR) tweak processor trampoline code.
1250
1251		- (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1252		  secondary processors.
1253
1254		- (if schedhz!=0) call schedclock regardless of the value of
1255		  curlwp.
1256
1257		- of course, update MD users of scheduler/switching API.
