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
25#   Description:  Purpose and intention of the branch
26#   Status:	  Active/Terminated/Dormant
27#   Start Date:	  date first instantiated
28#   End Date:	  date it was Terminated/made_Dormant, if any
29#   Base Tag:	  netbsd-1-5-base, etc.
30#   Maintainer:	  Somebody to blame.

340Branch:		ad-audiomp
341Description:	Add MP locking to the audio drivers
342Status:		Terminated
343Start Date:	28 February 2007
344End Date:	7 December 2008
345Base Tag:	ad-audiomp-base
346Maintainer:	Andrew Doran <ad@NetBSD.org>
347Scope:		kernel
348Notes:		Making the audio drivers MP safe is necessary before efforts
349		can be made to make the VM system MP safe. About 1/2 of the
350		drivers are converted, the remaining 1/2 need more changes.
351
352		As of import this is snapshot of work in progress and so
353		may not compile; in particular the midi changes are very
354		much "in progress". The audio component has been tested
355		and verified to work with emuxki and auvia. There may
356		be a locking issue in the ac97 code at boot.
357
358		The are two locks per device instance, an ISR lock and
359		a character device lock. The ISR lock replaces calls to
360		splaudio()/splx(), and will be held across calls to device
361		methods which were called at splaudio() before (e.g.
362		trigger_output). The character device lock is held across
363		calls to nearly all of the methods, excluding some only
364		used for initialization, e.g. get_locks. This needs to be
365		documented at merge time.
366
367		To test on a multi way x86 system, search for "mpsafe" in
368		x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job
369		that will acquire the ISR lock (depends on the hardware, but
370		"while true; do mixerctl -a > /dev/null; done" may suffice).
371		Play audio, run lockstat and verify that that there is
372		contention on the ISR lock.

387Start Date:	8 January 2020

389Base Tag:	ad-namecache-base
390Maintainer:	Andrew Doran <ad@NetBSD.org>
391Scope:		src/sys src/common
392Notes:		1) Redo the namecache to focus on per-directory data
393		structures, removing the huge hashtable and nasty locking
394		scheme.
395
396		Initially this uses rbtrees (because that's what's there). 
397		The intent is that ultimately some other data structure
398		will be used.
399
400		2) Experiment with having namei() traverse the cache and
401		avoid vnode locks except for the leaf in the totally
402		in-cache case.

703Scope:		src/sys
704Notes:		No longer active due to the lack of time. If you plan to
705		continue this branch, sys/netinet/in_pcb.h already contains
706		the proposed structure layout (which was roughly discussed
707		in the tech-net mailing list).
708		I also defined INP_*() macros to mimicate FreeBSD's inpcb
709		locking style, but currently they do nothing and are not
710		yet called at the correct places (needs discussion about
711		kernel fine-grained locking).
712		To continue this branch, one needs to read all the relevant
713		inpcb/in6pcb source files and change the function names,
714		structure names, structure fields according to the new
715		layout (in6pcb is gone).
716		Don't try to build a kernel from this branch because it won't
717		work. The missing pieces required to do a complete build
718		were not committed because they were incomplete and generated
719		panics.
720		You shouldn't need to worry about KAME syncs because
721		they did most of them by now.
722		After the work is done, you are required to test the branch
723		(before the merge to -current) with an interop IPv6 test.

808		This branch is intended to stage improvements for the

810		include not allocating memory while preparing to tsleep(),
811		reducing inappropriate upcall delivery (hopefully also
812		eliminating the need to mlock stacks), and being
813		able to pthread_kill() running threads. At this date,
814		most goals have been achieved. This branch also includes

827		to re-add syscall compatability so that SA-based libpthread
828		programs can run with a -current kernel. 1:1 threading will
829		remain the NetBSD-default. This branch will re-add necessary
830		upcall support, and will also serve as a chance to clean
831		out cruft that had accumulated in the implementation over

972Branch:		reinoud-bufcleanup
973Description:	implement and evaluate struct buf usage cleanup strategies.
974		Ideas currently in mind (preference for b):
975		a)
976			1. use of bio_ops per buffer.
977			2. allow chaining/overloading of functions in bio_ops
978			   and provide some private context.
979			3. extend the bio_ops with commonly used functionality
980			   like pending action counting, custom context passing,
981			   last minute processing of buffer data, buffer cache
982			   etc.
983			4. investigate the use of the kcont()
984			   continuation-passing framework for async io
985			   completion notification for bufs
986			...
987		b)
988			1. all sequencing use of B_CALL replaced by
989			   device-threads, if possible generic code around BUFQ
990			2. possibly use kcont() for async IO finished signaling
991			3. counter of pending and queued actions requestable
992			   by IOCTL interface?
993			4. implement `last minute buffer fixup' calls and maybe
994			   even finished I/O calls as vnode operations
995			...

1507		- Reorganize locking in UVM and serialize pmap(9) operations
1508		  on same page(s).  New lock order: [vmpage-lock] -> pmap-lock.
1509		  Based on the patch from ad@.
1510		- Simplify locking in pmap(9) modules by removing P->V locking.
1511		- Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock)
1512		  to share locks among UVM objects where necessary.
1513		- Rewrite and optimize x86 TLB shootdown code.
1514		- Unify /dev/mem et al in MI code and provide required locking.
1515
1516		Future work:
1517
1518		- Optimize pmap_remove() with tracking in struct vm_map_entry.

1528Notes:
1529		Code committed to the branch has booted to multiuser 
1530		on at least one system.
1531
1532		Not guaranteed to compile against mainline since -current
1533		may have changed incompatibly with the last branch update;
1534		use "cvs update -D" to roll-back the rest of the tree to match.
1535
1536		Please get explicit permission from the maintainer 
1537		before each commit, or your changes will be backed out.
1538		Other tags starting with sommerfeld_ are private to 
1539		the developer and are guaranteed to be unstable.
1540		Only the maintainer should move tags.
1541
1542		Note that this branch uses a DIFFERENT scheme for 
1543		syncing with the mainline.  the maintainer uses some private
1544		scripts for keeping them in sync; if you make commits 
1545		to the branch to "resynchronize" things, you'll
1546		probably do it wrong; instead, ask the maintainer to
1547		resynchronize things.

1680		   Work around this issue by turning on WAPBL_DEBUG_SERIALIZE
1681		   in rev 1.1.2.11 of vfs_wapbl.c.
1682		 - Removing large files (sparse only?) takes a long time.
1683		   Eg, a file created with
1684		      dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550
1685		   takes 0:00.00 to remove on my test box without logging and
1686		   0:22.25 to remove with logging.  No disk IO during this...
1687		 - sysinst should use in-fs logs now, not end-of-partition logs.

1779Base tag:	wrstuden-devbsize-base
1780Maintainer:	Bill Studenmund <wrstuden@NetBSD.org>
1781Scope:		kernel
1782Notes:		No longer active due to lack of time, and introduction
1783		of UBC. In terms of UBC, the primary cache for
1784		file data is the VM cache, which needs to operate
1785		in terms of VM pages. As no existing device has native
1786		pages the same size as our VM pages, there already is
1787		a mapping going on between the VM system and the
1788		underlying blocks. So it would be easier and cleaner
1789		to adjust that to deal w/ different block sizes.
1790		Also with UBC, all i/o is in terms of bytes at an offset
1791		with a certain length, so the exact block size isn't a big
1792		deal.
1793
1794		Any other wrstuden-devbsize tag may (and should) go away.

1830		How to adapt a port?
1831
1832		- unify cpu_switch, cpu_exit, cpu_switchto into
1833		  a single cpu_switchto.  see cpu_switchto.9.
1834
1835		- implement cpu_idle.  see cpu_idle.9.
1836
1837		- add a flag argument to cpu_need_resched.
1838		  handle RESCHED_IMMED flag, which means "cause a preemption
1839		  as soon as possible."  eg. in the case of MULTIPROCESSOR,
1840		  send an IPI to the target cpu.
1841
1842		- "curlwp == NULL" is not a valid check for idle state anymore.
1843		  use "(curlwp->l_flag & LW_IDLE) != 0" instead.  curlwp is
1844		  almost always non-NULL, with exceptions like early on boot.
1845
1846		- remove idle pcbs.
1847
1848		- (if MULTIPROCESSOR) tweak processor trampoline code.
1849
1850		- (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1851		  secondary processors.
1852
1853		- (if schedhz!=0) call schedclock regardless of the value of
1854		  curlwp.
1855
1856		- of course, update MD users of scheduler/switching API.

2171Notes:		Removing knowledge of the scheduler and its run queues
2172		from the machine-dependent context switch code is the
2173		first step in cleaning up the scheduler.  It is necessary
2174		for the newlock branch, making the scheduler SMP friendly,
2175		adding real-time scheduler extensions, and reducing the
2176		number of code paths for LWP and proc switching.

2242
2243				- Talk to ad@ -- figure out of non-atomic
2244				  mutex / rwlock release is actually safe.
2245
2246		arm		- Consider using a RAS technique like
2247				  MIPS uses for _lock_cas() and the mutex
2248				  stubs.  Possibly do more than one atomic
2249				  op as a RAS.  Possibly implement mutex
2250				  stubs using the technique.
2251
2252		m68k		- Need to do 68010 support.
2253		
2254		i386		- Need to change when x86_patch() is called
2255				  so we can test ncpus.
2256
2257		powerpc		- Figure out if we need barriers in the

2259
2260		x86_64		- Need to change when x86_patch() is called
