      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,
     33 #		  who-may-commit policies, etc.

    340 Branch:		ad-audiomp
    341 Description:	Add MP locking to the audio drivers
    342 Status:		Terminated
    343 Start Date:	28 February 2007
    344 End Date:	7 December 2008
    345 Base Tag:	ad-audiomp-base
    346 Maintainer:	Andrew Doran <ad (a] NetBSD.org>
    347 Scope:		kernel
    348 Notes:		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.

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

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    672 Notes:		No longer active due to the lack of time.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

    703 Notes:		This branch is based off of the netbsd-4 branch!
    704 		This branch is intended to stage improvements for the
    705 		Scheduler Activations system for NetBSD 4. Improvements
    706 		include not allocating memory while preparing to tsleep(),
    707 		reducing inappropriate upcall delivery (hopefully also
    708 		eliminating the need to mlock stacks), and being
    709 		able to pthread_kill() running threads. At this date,

    721 Notes:		This branch is intended to revive Scheduler Activations

    723 		to re-add syscall compatability so that SA-based libpthread
    724 		programs can run with a -current kernel. 1:1 threading will
    725 		remain the NetBSD-default. This branch will re-add necessary
    726 		upcall support, and will also serve as a chance to clean
    727 		out cruft that had accumulated in the implementation over
    728 		time.

    868 Branch:		reinoud-bufcleanup
    869 Description:	implement and evaluate struct buf usage cleanup strategies.
    870 		Ideas currently in mind (preference for b):
    871 		a)
    872 			1. use of bio_ops per buffer.
    873 			2. allow chaining/overloading of functions in bio_ops
    874 			   and provide some private context.
    875 			3. extend the bio_ops with commonly used functionality
    876 			   like pending action counting, custom context passing,
    877 			   last minute processing of buffer data, buffer cache
    878 			   etc.
    879 			4. investigate the use of the kcont()
    880 			   continuation-passing framework for async io
    881 			   completion notification for bufs
    882 			...
    883 		b)
    884 			1. all sequencing use of B_CALL replaced by
    885 			   device-threads, if possible generic code around BUFQ
    886 			2. possibly use kcont() for async IO finished signaling
    887 			3. counter of pending and queued actions requestable
    888 			   by IOCTL interface?
    889 			4. implement `last minute buffer fixup' calls and maybe
    890 			   even finished I/O calls as vnode operations
    891 			...

   1405 		  Based on the patch from ad@.
   1406 		- Simplify locking in pmap(9) modules by removing P->V locking.
   1407 		- Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock)
   1408 		  to share locks among UVM objects where necessary.
   1409 		- Rewrite and optimize x86 TLB shootdown code.
   1410 		- Unify /dev/mem et al in MI code and provide required locking.
   1411 
   1412 		Future work:
   1413 
   1414 		- Optimize pmap_remove() with tracking in struct vm_map_entry.

   1678 Notes:		No longer active due to lack of time, and introduction
   1679 		of UBC. In terms of UBC, the primary cache for
   1680 		file data is the VM cache, which needs to operate
   1681 		in terms of VM pages. As no existing device has native
   1682 		pages the same size as our VM pages, there already is
   1683 		a mapping going on between the VM system and the
   1684 		underlying blocks. So it would be easier and cleaner
   1685 		to adjust that to deal w/ different block sizes.
   1686 		Also with UBC, all i/o is in terms of bytes at an offset
   1687 		with a certain length, so the exact block size isn't a big
   1688 		deal.

   1726 		How to adapt a port?
   1727 
   1728 		- unify cpu_switch, cpu_exit, cpu_switchto into
   1729 		  a single cpu_switchto.  see cpu_switchto.9.
   1730 
   1731 		- implement cpu_idle.  see cpu_idle.9.
   1732 
   1733 		- add a flag argument to cpu_need_resched.
   1734 		  handle RESCHED_IMMED flag, which means "cause a preemption
   1735 		  as soon as possible."  eg. in the case of MULTIPROCESSOR,
   1736 		  send an IPI to the target cpu.
   1737 
   1738 		- "curlwp == NULL" is not a valid check for idle state anymore.
   1739 		  use "(curlwp->l_flag & LW_IDLE) != 0" instead.  curlwp is
   1740 		  almost always non-NULL, with exceptions like early on boot.
   1741 
   1742 		- remove idle pcbs.
   1743 
   1744 		- (if MULTIPROCESSOR) tweak processor trampoline code.
   1745 
   1746 		- (if MULTIPROCESSOR) call mi_cpu_attach when attaching
   1747 		  secondary processors.
   1748 
   1749 		- (if schedhz!=0) call schedclock regardless of the value of
   1750 		  curlwp.
   1751 
   1752 		- of course, update MD users of scheduler/switching API.

   2133 
   2134 		all		- Need to replace mb_*() with membar_*().
   2135 
   2136 				- Audit MUTEX_CAS() and RWLOCK_CAS() uses
   2137 				  to see of membar_enter() is required here.
   2138 
   2139 				- Talk to ad@ -- figure out of non-atomic
   2140 				  mutex / rwlock release is actually safe.
   2141 
   2142 		arm		- Consider using a RAS technique like
   2143 				  MIPS uses for _lock_cas() and the mutex
   2144 				  stubs.  Possibly do more than one atomic
   2145 				  op as a RAS.  Possibly implement mutex
   2146 				  stubs using the technique.
   2147 
   2148 		m68k		- Need to do 68010 support.
   2149 		
   2150 		i386		- Need to change when x86_patch() is called
   2151 				  so we can test ncpus.
   2152 
   2153 		powerpc		- Figure out if we need barriers in the
   2154 				  atomic ops themselves (hopefully not!)
   2155 
   2156 		x86_64		- Need to change when x86_patch() is called
   2157 				  so we can test ncpus.
