      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

    211 Branch:		ad-audiomp
    212 Description:	Add MP locking to the audio drivers
    213 Status:		Active
    214 Start Date:	28 Febuary 2007
    215 End Date:
    216 Base Tag:	ad-audiomp-base
    217 Maintainer:	Andrew Doran <ad (a] NetBSD.org>
    218 Scope:		kernel
    219 Notes:		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.

    245 Branch:		bjh21-hydra
    246 Description:	Simtec Hydra support and ARM SMP in general
    247 Status:		Dormant
    248 Start Date:	18 Oct 2002
    249 End Date:
    250 Base Tag:	bjh21-hydra-base
    251 Maintainer:	Ben Harris <bjh21 (a] NetBSD.org>
    252 Scope:		sys/arch/arm sys/arch/acorn32
    253 Notes:		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 
    257 Branch:		gmcgarry_ctxsw
    258 Description:	Separate scheduler from context-switch code
    259 Status:		Dormant
    260 Start Date:	18 December 2002
    261 End Date:
    262 Base Tag:	gmcgarry_ctxsw_base
    263 Maintainer:	Gregory McGarry <gmcgarry (a] NetBSD.org>
    264 Scope:		kernel
    265 Notes:		Removing knowledge of the schedular and its run queues
    266 		from the machine-dependent context switch code is the
    267 		first step in cleaning up the scheduler.  It is necessary
    268 		for the newlock branch, making the scheduler SMP friendly,
    269 		adding real-time scheduler extensions, and reducing the
    270 		number of code paths for LWP and proc switching.
    271 
    272 Branch:		gmcgarry_ucred

    289 Scope:		kernel
    290 Notes:		http://www.kame.net
    291 		Used for "reference" purposes for early part of KAME
    292 		integration effort.  The branch is not actively used, as I
    293 		(itojun) use patch(1) and diff(1) for the KAME syncs.

    324 Base Tag:	newlock-base
    325 Maintainer:	Jason R. Thorpe <thorpej (a] NetBSD.org>
    326 Scope:		Kernel
    327 Notes:		The goal is to replace the existing lockmgr() and
    328 		simple_lock() based locking mechanisms with the
    329 		primitives found in Solaris: mutexes and rwlocks.
    330 		Superseeded by the newlock2 branch.
    331 
    332 Branch:		newlock2
    333 Description:	New locking primitives, based on Solaris's
    334 Status:		Terminated
    335 Start Date:	September 9, 2006
    336 End Date:	Febuary 12, 2007
    337 Base Tag:	newlock2-base
    338 Maintainer:	Andrew Doran <ad (a] NetBSD.org>
    339 Scope:		Kernel
    340 Notes:		As per the newlock branch, however given the amount of time
    341 		the original branch has lain dormant, a new one has been
    342 		created.  Goals:
    343 		- Implement new locking primitives on most-used ports.
    344 		- Minor locking improvements.
    345 		- Remove spinlockmgr().

    347 Branch:	  	pkgviews

    357 		within the same tree
    358 
    359 Branch:		ppcoea-renovation
    360 Description:	General renovation and cleanup of all OEA PowerPC ports.
    361 Status:		Active
    362 Start Date:	30 April 2007
    363 End Date:
    364 Base Tag:	ppcoea-renovation-base
    365 Maintainer:	Tim Rightnour <garbled (a] netbsd.org>
    366 Scope:		src/sys/arch
    367 Notes:		This branch is for a general cleanup of all OEA-based PowerPC
    368 		ports.  The general concept is to get them all compiling, and
    369 		sharing as much code as possible.  All developers are welcome
    370 		to commit to this branch.
    371 
    372 Branch:		rpaulo-netinet-merge-pcb
    373 Description:	merge in6pcb with inpcb
    374 Status:		Dormant
    375 Start Date:	Wed Feb 01 2006
    376 End Date:	
    377 Base Tag:	rpaulo-netinet-merge-pcb-base
    378 Maintainer:	Rui Paulo <rpaulo (a] NetBSD.org>
    379 Scope:		src/sys
    380 Notes:		No longer active due to the lack of time. If you plan to
    381 		continue this branch, sys/netinet/in_pcb.h already contains
    382 		the proposed structure layout (which was roughly discussed
    383 		in the tech-net mailing list).
    384 		I also defined INP_*() macros to mimicate FreeBSD's inpcb
    385 		locking style, but currently they do nothing and are not
    386 		yet called at the correct places (needs discussion about
    387 		kernel fine-grained locking).
    388 		To continue this branch, one needs to read all the relevant
    389 		inpcb/in6pcb source files and change the function names,
    390 		structure names, structure fileds according to the new
    391 		layout (in6pcb is gone).
    392 		Don't try to build a kernel from this branch because it won't
    393 		work. The missing pieces required to do a complete build
    394 		were not committed because they were incomplete and generated
    395 		panics.
    396 		You shouldn't need to worry about KAME syncs because
    397 		they did most of them by now.
    398 		After the work is done, you are required to test the branch
    399 		(before the merge to -current) with an interop IPv6 test.

    418 Branch:		vmlocking
    419 Description:	Make memory allocators and trap handling MP safe
    420 Status:		Active
    421 Start Date:	13 March 2007
    422 End Date:
    423 Base Tag:	vmlocking-base
    424 Maintainer:	Andrew Doran <ad (a] NetBSD.org>
    425 Scope:		kernel
    426 Notes:
    427 		- Replace all simplelocks with mutexes
    428 		- Remove spinlockmgr
    429 		- Make memory allocators MP safe
    430 		- Make trap handling MP safe: push kernel lock acquire
    431 		  back into pager ops.
    432 
    433 		Only i386 is currently update.  Most per architecture
    434 		changes need to be made in the pmap module.  LFS is not
    435 		currently stable due interaction between the pagedaemon (?)
    436 		and the HOLDRELE() in lfs_segment.c.  It may trash your
    437 		filesystem..
    438 
    439 		Most of the locks replaced are now sleep/adaptive locks or
    440 		spin locks at IPL_VM.  Assuming audio interrupt handlers
    441 		are made MP safe there are far fewer potential deadlocks
    442 		against the kernel lock.
    443 
    444 		v_interlock becomes an adaptive mutex so now acquring
    445 		it can potentially block, similarly for other locks
    446 		that were before simplelocks.  This needs to be audited
    447 		carefully.
    448 
    449 		Use vnodes in general needs to be audited, as vnodes can
    450 		now be inspected without the kernel lock held.
    451 
    452 		Acquiring locks in the pmap module can now block, meaning
    453 		that the current pmap, cpu or lazy pmap status can change
    454 		out from underneath the requestor.  This also needs to be
    455 		audited.
    456 
    457 		Currently, i386 has the necessary modifications, and has
    458 		trap handling and a few calls to allocators out from under
    459 		the kernel lock.  There are still problems that need to be
    460 		debugged.
    461 
    462 		Need to check that whenever a lock is initialized, it is
    463 		also destroyed.
    464 
    465 		Lots of testing required.
    466 
    467 Branch:		yamt-idlelwp
    468 Description:	idle lwp, and some changes depending on it.
    469 
    470 		1. separate context switching and thread scheduling.

    500 		How to adapt a port?
    501 
    502 		- unify cpu_switch, cpu_exit, cpu_switchto into
    503 		  a single cpu_switchto.  see cpu_switchto.9.
    504 
    505 		- implement cpu_idle.  see cpu_idle.9.
    506 
    507 		- add a flag argument to cpu_need_resched.
    508 		  handle RESCHED_IMMED flag, which means "cause a preemption
    509 		  as soon as possible."  eg. in the case of MULTIPROCESSOR,
    510 		  send an IPI to the target cpu.
    511 
    512 		- "curlwp == NULL" is not a valid check for idle state anymore.
    513 		  use "(curlwp->l_flag & LW_IDLE) != 0" instead.  curlwp is
    514 		  almost always non-NULL, with exceptions like early on boot.
    515 
    516 		- remove idle pcbs.
    517 
    518 		- (if MULTIPROCESSOR) tweak processor trampoline code.
    519 
    520 		- (if MULTIPROCESSOR) call mi_cpu_attach when attaching
    521 		  secondary processors.
    522 
    523 		- (if schedhz!=0) call schedclock regardless of the value of
    524 		  curlwp.
    525 
    526 		- of course, update MD users of scheduler/switching API.

    531 			1. support operations (esp. bus_dma load) on

    533 			2. unify mbuf and buf.
    534 			   (or, at least some parts of them)

    546 Description:	implement and evaluate struct buf usage cleanup strategies.
    547 		Ideas currently in mind (preference for b):
    548 		a)
    549 			1. use of bio_ops per buffer.
    550 			2. allow chaining/overloading of functions in bio_ops
    551 			   and provide some private context.
    552 			3. extend the bio_ops with commenly used functionality
    553 			   like pending action counting, custom context passing,
    554 			   last minute processing of buffer data, buffer cache
    555 			   etc.
    556 			4. investigate the use of the kcont()
    557 			   continuation-passing framework for async io
    558 			   completion notification for bufs
    559 			...
    560 		b)
    561 			1. all sequencing use of B_CALL replaced by
    562 			   device-threads, if possible generic code around BUFQ
    563 			2. possibly use kcont() for async IO finished signalling
    564 			3. counter of pending and queued actions requestable
    565 			   by IOCTL interface?
    566 			4. implement `last minute buffer fixup' calls and maybe
    567 			   even finished I/O calls as vnode operations
    568 			...

    965 Notes:
    966 		Code committed to the branch has booted to multiuser 
    967 		on at least one system.
    968 
    969 		Not guaranteed to compile against mainline since -current
    970 		may have changed incompatibly with the last branch update;
    971 		use "cvs update -D" to roll-back the rest of the tree to match.
    972 
    973 		Please get explicit permission from the maintainer 
    974 		before each commit, or your changes will be backed out.
    975 		Other tags starting with sommerfeld_ are private to 
    976 		the developer and are guaranteed to be unstable.
    977 		Only the maintainer should move tags.
    978 
    979 		Note that this branch uses a DIFFERENT scheme for 
    980 		synching with the mainline.  the maintainer uses some private
    981 		scripts for keeping them in synch; if you make commits 
    982 		to the branch to "resynchronize" things, you'll
    983 		probably do it wrong; instead, ask the maintainer to
    984 		resynchronize things.

   1113 Notes:		No longer active due to lack of time, and introduction
   1114 		of UBC. In terms of UBC, the primary cache for
   1115 		file data is the VM cache, which needs to operate
   1116 		in terms of VM pages. As no existing device has native
   1117 		pages the same size as our VM pages, there already is
   1118 		a mapping going on between the VM system and the
   1119 		underlying blocks. So it would be easier and cleaner
   1120 		to adjust that to deal w/ different block sizes.
   1121 		Also with UBC, all i/o is in terms of bytes at an offset
   1122 		with a certain length, so the exact block size isn't a big
   1123 		deal.
   1124 
   1125 		Any other wrstuden-devbsize tag may (and should) go away.
