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.
31#   Scope:	  Portion of the tree covered.
32#   Notes:	  Various other info, perhaps explanation of special tags,

329Branch:		ad-audiomp
330Description:	Add MP locking to the audio drivers
331Status:		Terminated
332Start Date:	28 February 2007
333End Date:	7 December 2008
334Base Tag:	ad-audiomp-base
335Maintainer:	Andrew Doran <ad@NetBSD.org>
336Scope:		kernel
337Notes:		Making the audio drivers MP safe is necessary before efforts
338		can be made to make the VM system MP safe. About 1/2 of the
339		drivers are converted, the remaining 1/2 need more changes.
340
341		As of import this is snapshot of work in progress and so
342		may not compile; in particular the midi changes are very
343		much "in progress". The audio component has been tested
344		and verified to work with emuxki and auvia. There may
345		be a locking issue in the ac97 code at boot.
346
347		The are two locks per device instance, an ISR lock and
348		a character device lock. The ISR lock replaces calls to
349		splaudio()/splx(), and will be held across calls to device
350		methods which were called at splaudio() before (e.g.
351		trigger_output). The character device lock is held across
352		calls to nearly all of the methods, excluding some only
353		used for initialization, e.g. get_locks. This needs to be
354		documented at merge time.
355
356		To test on a multi way x86 system, search for "mpsafe" in
357		x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job
358		that will acquire the ISR lock (depends on the hardware, but
359		"while true; do mixerctl -a > /dev/null; done" may suffice).
360		Play audio, run lockstat and verify that that there is
361		contention on the ISR lock.

660Scope:		src/sys
661Notes:		No longer active due to the lack of time. If you plan to
662		continue this branch, sys/netinet/in_pcb.h already contains
663		the proposed structure layout (which was roughly discussed
664		in the tech-net mailing list).
665		I also defined INP_*() macros to mimicate FreeBSD's inpcb
666		locking style, but currently they do nothing and are not
667		yet called at the correct places (needs discussion about
668		kernel fine-grained locking).
669		To continue this branch, one needs to read all the relevant
670		inpcb/in6pcb source files and change the function names,
671		structure names, structure fields according to the new
672		layout (in6pcb is gone).
673		Don't try to build a kernel from this branch because it won't
674		work. The missing pieces required to do a complete build
675		were not committed because they were incomplete and generated
676		panics.
677		You shouldn't need to worry about KAME syncs because
678		they did most of them by now.
679		After the work is done, you are required to test the branch
680		(before the merge to -current) with an interop IPv6 test.

692Notes:		This branch is based off of the netbsd-4 branch!
693		This branch is intended to stage improvements for the
694		Scheduler Activations system for NetBSD 4. Improvements
695		include not allocating memory while preparing to tsleep(),
696		reducing inappropriate upcall delivery (hopefully also
697		eliminating the need to mlock stacks), and being
698		able to pthread_kill() running threads. At this date,
699		most goals have been achieved. This branch also includes
700		fixes to gdb to support working with threaded apps.

710Notes:		This branch is intended to revive Scheduler Activations
711		in -current in the 5.0 era. This branch's main goal is
712		to re-add syscall compatability so that SA-based libpthread
713		programs can run with a -current kernel. 1:1 threading will
714		remain the NetBSD-default. This branch will re-add necessary
715		upcall support, and will also serve as a chance to clean
716		out cruft that had accumulated in the implementation over
717		time.

857Branch:		reinoud-bufcleanup
858Description:	implement and evaluate struct buf usage cleanup strategies.
859		Ideas currently in mind (preference for b):
860		a)
861			1. use of bio_ops per buffer.
862			2. allow chaining/overloading of functions in bio_ops
863			   and provide some private context.
864			3. extend the bio_ops with commonly used functionality
865			   like pending action counting, custom context passing,
866			   last minute processing of buffer data, buffer cache
867			   etc.
868			4. investigate the use of the kcont()
869			   continuation-passing framework for async io
870			   completion notification for bufs
871			...
872		b)
873			1. all sequencing use of B_CALL replaced by
874			   device-threads, if possible generic code around BUFQ
875			2. possibly use kcont() for async IO finished signaling
876			3. counter of pending and queued actions requestable
877			   by IOCTL interface?
878			4. implement `last minute buffer fixup' calls and maybe
879			   even finished I/O calls as vnode operations
880			...

1554Notes:		Still has a number of issues:
1555		 - Some heavy workload performance issues on SMP machines.
1556		   Work around this issue by turning on WAPBL_DEBUG_SERIALIZE
1557		   in rev 1.1.2.11 of vfs_wapbl.c.
1558		 - Removing large files (sparse only?) takes a long time.
1559		   Eg, a file created with
1560		      dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550
1561		   takes 0:00.00 to remove on my test box without logging and
1562		   0:22.25 to remove with logging.  No disk IO during this...
1563		 - sysinst should use in-fs logs now, not end-of-partition logs.

1651		different block sizes. Also DEV_BSIZE would go away.

1653Start Date:	Aug or Sept 1999
1654End Date:	1 Apr 2000
1655Base tag:	wrstuden-devbsize-base
1656Maintainer:	Bill Studenmund <wrstuden@NetBSD.org>
1657Scope:		kernel
1658Notes:		No longer active due to lack of time, and introduction
1659		of UBC. In terms of UBC, the primary cache for
1660		file data is the VM cache, which needs to operate
1661		in terms of VM pages. As no existing device has native
1662		pages the same size as our VM pages, there already is
1663		a mapping going on between the VM system and the
1664		underlying blocks. So it would be easier and cleaner
1665		to adjust that to deal w/ different block sizes.
1666		Also with UBC, all i/o is in terms of bytes at an offset
1667		with a certain length, so the exact block size isn't a big
1668		deal.
1669
1670		Any other wrstuden-devbsize tag may (and should) go away.

1706		How to adapt a port?
1707
1708		- unify cpu_switch, cpu_exit, cpu_switchto into
1709		  a single cpu_switchto.  see cpu_switchto.9.
1710
1711		- implement cpu_idle.  see cpu_idle.9.
1712
1713		- add a flag argument to cpu_need_resched.
1714		  handle RESCHED_IMMED flag, which means "cause a preemption
1715		  as soon as possible."  eg. in the case of MULTIPROCESSOR,
1716		  send an IPI to the target cpu.
1717
1718		- "curlwp == NULL" is not a valid check for idle state anymore.
1719		  use "(curlwp->l_flag & LW_IDLE) != 0" instead.  curlwp is
1720		  almost always non-NULL, with exceptions like early on boot.
1721
1722		- remove idle pcbs.
1723
1724		- (if MULTIPROCESSOR) tweak processor trampoline code.
1725
1726		- (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1727		  secondary processors.
1728
1729		- (if schedhz!=0) call schedclock regardless of the value of
1730		  curlwp.
1731
1732		- of course, update MD users of scheduler/switching API.

2046Scope:		kernel
2047Notes:		Removing knowledge of the scheduler and its run queues
2048		from the machine-dependent context switch code is the
2049		first step in cleaning up the scheduler.  It is necessary
2050		for the newlock branch, making the scheduler SMP friendly,
2051		adding real-time scheduler extensions, and reducing the
2052		number of code paths for LWP and proc switching.

2113
2114		all		- Need to replace mb_*() with membar_*().
2115
2116				- Audit MUTEX_CAS() and RWLOCK_CAS() uses
2117				  to see of membar_enter() is required here.
2118
2119				- Talk to ad@ -- figure out of non-atomic
2120				  mutex / rwlock release is actually safe.
2121
2122		arm		- Consider using a RAS technique like
2123				  MIPS uses for _lock_cas() and the mutex
2124				  stubs.  Possibly do more than one atomic
2125				  op as a RAS.  Possibly implement mutex
2126				  stubs using the technique.
2127
2128		m68k		- Need to do 68010 support.
2129		
2130		i386		- Need to change when x86_patch() is called
2131				  so we can test ncpus.
2132
2133		powerpc		- Figure out if we need barriers in the
2134				  atomic ops themselves (hopefully not!)
2135
2136		x86_64		- Need to change when x86_patch() is called
2137				  so we can test ncpus.
