      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.

    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.

    269 Branch:		gmcgarry_ctxsw

    275 Maintainer:	Gregory McGarry <gmcgarry (a] NetBSD.org>
    276 Scope:		kernel
    277 Notes:		Removing knowledge of the schedular and its run queues
    278 		from the machine-dependent context switch code is the
    279 		first step in cleaning up the scheduler.  It is necessary
    280 		for the newlock branch, making the scheduler SMP friendly,
    281 		adding real-time scheduler extensions, and reducing the
    282 		number of code paths for LWP and proc switching.

    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.

    490 		Remaining MD work to do:
    491 
    492 		- Defer x86 npxsave interrupts to an process context (do
    493 		  aston() and handle from trap.c).
    494 
    495 		- Port other architectures.
    496 
    497 		Remaining MI work to do:
    498 
    499 		- Clean up vfs_busy/vfs_unbusy and mount/dounmount semantics
    500 		  so that lockmgr is not being used any more. Reference
    501 		  counting on struct mount is probably the best solution.
    502 
    503 		- Check + document locking around fields in struct mount.
    504 
    505 		- Check file systems that traverse mountpoint vnode lists.
    506 		  They need to use marker vnodes. Most already done.
    507 
    508 		- Re-write the itimer code to be MP safe and work in the
    509 		  presence of threaded soft interrupts.
    510 
    511 		- Check aliased vnode handling. There may be problems.
    512 
    513 		Remaining problems:
    514 
    515 		- tmpfs_rmdir occasionally leaks tmpfs_nodes. This could be
    516 		  an old problem but either way it needs to be fixed.
    517 
    518 		- UVM_FLAG_TRYLOCK is not sufficient in uvm_km.c because
    519 		  allocations will fail too often. It's needed for !kmem_map
    520 		  because sometimes allocations are made by threads that
    521 		  hold the map locked, which could cause other threads to
    522 		  wait long term even if they are trying to make a NOWAIT
    523 		  allocation.
    524 
    525 		- ffs+snapshots needs testing.
    526 
    527 		- LFS port has been fudged and it's probably borked.
    528 
    529 		- ext2fs panic on unmount.

    531 Branch:		yamt-lazymbuf
    532 Description:	implement and evaluate lazy mapping of mbuf external data pages
    533 		also, change the way to share mbuf external storage.
    534 		it's intended as the first step of larger changes.
    535 			1. support operations (esp. bus_dma load) on
    536 			   unmapped mbuf.
    537 			2. unify mbuf and buf.
    538 			   (or, at least some parts of them)
    539 			3. then it should be trivial to implement
    540 			   i/o coalescing, etc.

    554 Description:	implement and evaluate struct buf usage cleanup strategies.
    555 		Ideas currently in mind (preference for b):
    556 		a)
    557 			1. use of bio_ops per buffer.
    558 			2. allow chaining/overloading of functions in bio_ops
    559 			   and provide some private context.
    560 			3. extend the bio_ops with commenly used functionality
    561 			   like pending action counting, custom context passing,
    562 			   last minute processing of buffer data, buffer cache
    563 			   etc.
    564 			4. investigate the use of the kcont()
    565 			   continuation-passing framework for async io
    566 			   completion notification for bufs
    567 			...
    568 		b)
    569 			1. all sequencing use of B_CALL replaced by
    570 			   device-threads, if possible generic code around BUFQ
    571 			2. possibly use kcont() for async IO finished signalling
    572 			3. counter of pending and queued actions requestable
    573 			   by IOCTL interface?
    574 			4. implement `last minute buffer fixup' calls and maybe
    575 			   even finished I/O calls as vnode operations
    576 			...

   1052 
   1053 		Not guaranteed to compile against mainline since -current

   1055 		use "cvs update -D" to roll-back the rest of the tree to match.
   1056 
   1057 		Please get explicit permission from the maintainer 
   1058 		before each commit, or your changes will be backed out.
   1059 		Other tags starting with sommerfeld_ are private to

   1063 		Note that this branch uses a DIFFERENT scheme for 
   1064 		synching with the mainline.  the maintainer uses some private
   1065 		scripts for keeping them in synch; if you make commits 
   1066 		to the branch to "resynchronize" things, you'll
   1067 		probably do it wrong; instead, ask the maintainer to

   1197 Notes:		No longer active due to lack of time, and introduction
   1198 		of UBC. In terms of UBC, the primary cache for
   1199 		file data is the VM cache, which needs to operate
   1200 		in terms of VM pages. As no existing device has native
   1201 		pages the same size as our VM pages, there already is
   1202 		a mapping going on between the VM system and the
   1203 		underlying blocks. So it would be easier and cleaner
   1204 		to adjust that to deal w/ different block sizes.
   1205 		Also with UBC, all i/o is in terms of bytes at an offset
   1206 		with a certain length, so the exact block size isn't a big
   1207 		deal.

   1245 		How to adapt a port?
   1246 
   1247 		- unify cpu_switch, cpu_exit, cpu_switchto into
   1248 		  a single cpu_switchto.  see cpu_switchto.9.
   1249 
   1250 		- implement cpu_idle.  see cpu_idle.9.
   1251 
   1252 		- add a flag argument to cpu_need_resched.
   1253 		  handle RESCHED_IMMED flag, which means "cause a preemption
   1254 		  as soon as possible."  eg. in the case of MULTIPROCESSOR,
   1255 		  send an IPI to the target cpu.
   1256 
   1257 		- "curlwp == NULL" is not a valid check for idle state anymore.
   1258 		  use "(curlwp->l_flag & LW_IDLE) != 0" instead.  curlwp is
   1259 		  almost always non-NULL, with exceptions like early on boot.
   1260 
   1261 		- remove idle pcbs.
   1262 
   1263 		- (if MULTIPROCESSOR) tweak processor trampoline code.
   1264 
   1265 		- (if MULTIPROCESSOR) call mi_cpu_attach when attaching
   1266 		  secondary processors.
   1267 
   1268 		- (if schedhz!=0) call schedclock regardless of the value of
   1269 		  curlwp.
   1270 
   1271 		- of course, update MD users of scheduler/switching API.
