      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,

    329 Branch:		ad-audiomp
    330 Description:	Add MP locking to the audio drivers
    331 Status:		Terminated
    332 Start Date:	28 February 2007
    333 End Date:	7 December 2008
    334 Base Tag:	ad-audiomp-base
    335 Maintainer:	Andrew Doran <ad (a] NetBSD.org>
    336 Scope:		kernel
    337 Notes:		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.

    381 Notes:		This branch is used to develop the version of netpgp

    659 Maintainer:	Rui Paulo <rpaulo (a] NetBSD.org>
    660 Scope:		src/sys
    661 Notes:		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.

    692 Notes:		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.

    710 Notes:		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.

    858 Description:	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 			...

   1335 Notes:		This branch is for a general cleanup of all OEA-based PowerPC
   1336 		ports. OEA (Operating Environment Architecture) PowerPC refers
   1337 		to the 601, 603, 604, and similar chips.  Specifically, not the
   1338 		403/401 and other embedded chips. The general concept is to get
   1339 		them all compiling, and sharing as much code as possible.  All
   1340 		developers are welcome to commit to this branch.

   1385 		  Based on the patch from ad@.
   1386 		- Simplify locking in pmap(9) modules by removing P->V locking.
   1387 		- Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock)
   1388 		  to share locks among UVM objects where necessary.
   1389 		- Rewrite and optimize x86 TLB shootdown code.
   1390 		- Unify /dev/mem et al in MI code and provide required locking.
   1391 
   1392 		Future work:
   1393 
   1394 		- Optimize pmap_remove() with tracking in struct vm_map_entry.

   1407 
   1408 		Not guaranteed to compile against mainline since -current

   1410 		use "cvs update -D" to roll-back the rest of the tree to match.
   1411 
   1412 		Please get explicit permission from the maintainer 
   1413 		before each commit, or your changes will be backed out.
   1414 		Other tags starting with sommerfeld_ are private to 
   1415 		the developer and are guaranteed to be unstable.
   1416 		Only the maintainer should move tags.
   1417 
   1418 		Note that this branch uses a DIFFERENT scheme for 
   1419 		syncing with the mainline.  the maintainer uses some private
   1420 		scripts for keeping them in sync; if you make commits 
   1421 		to the branch to "resynchronize" things, you'll
   1422 		probably do it wrong; instead, ask the maintainer to
   1423 		resynchronize things.

   1558 		 - Removing large files (sparse only?) takes a long time.

   1560 		      dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550

   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.

   1657 Scope:		kernel
   1658 Notes:		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.

   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
