      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 #

    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

    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.

    350 Scope:		Kernel
    351 Notes:		The goal is to replace the existing lockmgr() and
    352 		simple_lock() based locking mechanisms with the
    353 		primitives found in Solaris: mutexes and rwlocks.
    354 		Superseeded by the newlock2 branch.
    355 
    356 Branch:		newlock2
    357 Description:	New locking primitives, based on Solaris's

    361 Base Tag:	newlock2-base
    362 Maintainer:	Andrew Doran <ad (a] NetBSD.org>
    363 Scope:		Kernel
    364 Notes:		As per the newlock branch, however given the amount of time
    365 		the original branch has lain dormant, a new one has been
    366 		created.  Goals:
    367 		- Implement new locking primitives on most-used ports.
    368 		- Minor locking improvements.
    369 		- Remove spinlockmgr().

    389 Maintainer:	Tim Rightnour <garbled (a] netbsd.org>
    390 Scope:		src/sys/arch
    391 Notes:		This branch is for a general cleanup of all OEA-based PowerPC
    392 		ports. OEA (Operating Environment Architecture) PowerPC refers
    393 		to the 601, 603, 604, and similar chips.  Specifically, not the
    394 		403/401 and other embedded chips. The general concept is to get
    395 		them all compiling, and sharing as much code as possible.  All
    396 		developers are welcome to commit to this branch.

    398 Branch:		rpaulo-netinet-merge-pcb

    400 Status:		Dormant
    401 Start Date:	Wed Feb 01 2006
    402 End Date:	
    403 Base Tag:	rpaulo-netinet-merge-pcb-base
    404 Maintainer:	Rui Paulo <rpaulo (a] NetBSD.org>
    405 Scope:		src/sys
    406 Notes:		No longer active due to the lack of time. If you plan to
    407 		continue this branch, sys/netinet/in_pcb.h already contains
    408 		the proposed structure layout (which was roughly discussed
    409 		in the tech-net mailing list).
    410 		I also defined INP_*() macros to mimicate FreeBSD's inpcb
    411 		locking style, but currently they do nothing and are not
    412 		yet called at the correct places (needs discussion about
    413 		kernel fine-grained locking).
    414 		To continue this branch, one needs to read all the relevant
    415 		inpcb/in6pcb source files and change the function names,
    416 		structure names, structure fileds according to the new
    417 		layout (in6pcb is gone).
    418 		Don't try to build a kernel from this branch because it won't
    419 		work. The missing pieces required to do a complete build
    420 		were not committed because they were incomplete and generated
    421 		panics.
    422 		You shouldn't need to worry about KAME syncs because
    423 		they did most of them by now.
    424 		After the work is done, you are required to test the branch
    425 		(before the merge to -current) with an interop IPv6 test.

    453 Notes:		This branch is based off of the netbsd-4 branch!
    454 		This branch is intended to stage improvements for the
    455 		Scheduler Activations system for NetBSD 4. Improvements
    456 		include not allocating memory while preparing to tsleep(),
    457 		reducing inappropriate upcall delivery (hopefully also
    458 		eliminating the need to mlock stacks), and being
    459 		able to pthread_kill() running threads.

    468 Scope:		kernel
    469 Notes:
    470 		- Replace all simplelocks with mutexes
    471 		- Remove spinlockmgr
    472 		- Make memory allocators MP safe
    473 		- Make trap handling MP safe: push kernel lock acquire
    474 		  back into pager ops.
    475 
    476 		Only i386 is currently update.  Most per architecture
    477 		changes need to be made in the pmap module.  LFS is not
    478 		currently stable due interaction between the pagedaemon (?)
    479 		and the HOLDRELE() in lfs_segment.c.  It may trash your
    480 		filesystem..
    481 
    482 		Most of the locks replaced are now sleep/adaptive locks or
    483 		spin locks at IPL_VM.  Assuming audio interrupt handlers
    484 		are made MP safe there are far fewer potential deadlocks
    485 		against the kernel lock.
    486 
    487 		v_interlock becomes an adaptive mutex so now acquring
    488 		it can potentially block, similarly for other locks
    489 		that were before simplelocks.  This needs to be audited
    490 		carefully.
    491 
    492 		Use vnodes in general needs to be audited, as vnodes can
    493 		now be inspected without the kernel lock held.
    494 
    495 		Acquiring locks in the pmap module can now block, meaning
    496 		that the current pmap, cpu or lazy pmap status can change
    497 		out from underneath the requestor.  This also needs to be
    498 		audited.
    499 
    500 		Currently, i386 has the necessary modifications, and has
    501 		trap handling and a few calls to allocators out from under
    502 		the kernel lock.  There are still problems that need to be
    503 		debugged.
    504 
    505 		Need to check that whenever a lock is initialized, it is
    506 		also destroyed.
    507 
    508 		Lots of testing required.

    510 Branch:		yamt-lazymbuf
    511 Description:	implement and evaluate lazy mapping of mbuf external data pages
    512 		also, change the way to share mbuf external storage.
    513 		it's intended as the first step of larger changes.
    514 			1. support operations (esp. bus_dma load) on
    515 			   unmapped mbuf.
    516 			2. unify mbuf and buf.
    517 			   (or, at least some parts of them)
    518 			3. then it should be trivial to implement
    519 			   i/o coalescing, etc.

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

    952 Notes:
    953 		Code committed to the branch has booted to multiuser 
    954 		on at least one system.
    955 
    956 		Not guaranteed to compile against mainline since -current
    957 		may have changed incompatibly with the last branch update;
    958 		use "cvs update -D" to roll-back the rest of the tree to match.
    959 
    960 		Please get explicit permission from the maintainer 
    961 		before each commit, or your changes will be backed out.
    962 		Other tags starting with sommerfeld_ are private to 
    963 		the developer and are guaranteed to be unstable.
    964 		Only the maintainer should move tags.
    965 
    966 		Note that this branch uses a DIFFERENT scheme for 
    967 		synching with the mainline.  the maintainer uses some private
    968 		scripts for keeping them in synch; if you make commits 
    969 		to the branch to "resynchronize" things, you'll
    970 		probably do it wrong; instead, ask the maintainer to
    971 		resynchronize things.

   1100 Notes:		No longer active due to lack of time, and introduction
   1101 		of UBC. In terms of UBC, the primary cache for
   1102 		file data is the VM cache, which needs to operate
   1103 		in terms of VM pages. As no existing device has native
   1104 		pages the same size as our VM pages, there already is
   1105 		a mapping going on between the VM system and the
   1106 		underlying blocks. So it would be easier and cleaner
   1107 		to adjust that to deal w/ different block sizes.
   1108 		Also with UBC, all i/o is in terms of bytes at an offset
   1109 		with a certain length, so the exact block size isn't a big
   1110 		deal.
   1111 
   1112 		Any other wrstuden-devbsize tag may (and should) go away.

   1148 		How to adapt a port?
   1149 
   1150 		- unify cpu_switch, cpu_exit, cpu_switchto into
   1151 		  a single cpu_switchto.  see cpu_switchto.9.
   1152 
   1153 		- implement cpu_idle.  see cpu_idle.9.
   1154 
   1155 		- add a flag argument to cpu_need_resched.
   1156 		  handle RESCHED_IMMED flag, which means "cause a preemption
   1157 		  as soon as possible."  eg. in the case of MULTIPROCESSOR,
   1158 		  send an IPI to the target cpu.
   1159 
   1160 		- "curlwp == NULL" is not a valid check for idle state anymore.
   1161 		  use "(curlwp->l_flag & LW_IDLE) != 0" instead.  curlwp is
   1162 		  almost always non-NULL, with exceptions like early on boot.
   1163 
   1164 		- remove idle pcbs.
   1165 
   1166 		- (if MULTIPROCESSOR) tweak processor trampoline code.
   1167 
   1168 		- (if MULTIPROCESSOR) call mi_cpu_attach when attaching
   1169 		  secondary processors.
   1170 
   1171 		- (if schedhz!=0) call schedclock regardless of the value of
   1172 		  curlwp.
   1173 
   1174 		- of course, update MD users of scheduler/switching API.
