      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 #

    232 Branch:		ad-audiomp
    233 Description:	Add MP locking to the audio drivers
    234 Status:		Terminated
    235 Start Date:	28 February 2007
    236 End Date:	7 December 2008
    237 Base Tag:	ad-audiomp-base
    238 Maintainer:	Andrew Doran <ad (a] NetBSD.org>
    239 Scope:		kernel
    240 Notes:		Making the audio drivers MP safe is necessary before efforts
    241 		can be made to make the VM system MP safe. About 1/2 of the
    242 		drivers are converted, the remaining 1/2 need more changes.
    243 
    244 		As of import this is snapshot of work in progress and so
    245 		may not compile; in particular the midi changes are very
    246 		much "in progress". The audio component has been tested
    247 		and verified to work with emuxki and auvia. There may
    248 		be a locking issue in the ac97 code at boot.
    249 
    250 		The are two locks per device instance, an ISR lock and
    251 		a character device lock. The ISR lock replaces calls to
    252 		splaudio()/splx(), and will be held across calls to device
    253 		methods which were called at splaudio() before (e.g.
    254 		trigger_output). The character device lock is held across
    255 		calls to nearly all of the methods, excluding some only
    256 		used for initialization, e.g. get_locks. This needs to be
    257 		documented at merge time.
    258 
    259 		To test on a multi way x86 system, search for "mpsafe" in
    260 		x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job
    261 		that will acquire the ISR lock (depends on the hardware, but
    262 		"while true; do mixerctl -a > /dev/null; done" may suffice).
    263 		Play audio, run lockstat and verify that that there is
    264 		contention on the ISR lock.

    493 Base Tag:	rmind-uvmplock-base
    494 Maintainer:	Mindaugas Rasiukevicius <rmind (a] netbsd.org>
    495 Scope:		Kernel
    496 Notes:		Goals:
    497 
    498 		- Reorganize locking in UVM and serialize pmap(9) operations
    499 		  on same page(s).  New lock order: [vmpage-lock] -> pmap-lock.
    500 		  Based on the patch from ad@.
    501 		- Simplify locking in pmap(9) modules by removing P->V locking.
    502 		- Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock)
    503 		  to share locks among UVM objects where necessary.
    504 		- Optimize pmap_remove() with tracking in struct vm_map_entry.
    505 		- Unify /dev/mem et al in MI code and provide required locking.

    513 Maintainer:	Rui Paulo <rpaulo (a] NetBSD.org>
    514 Scope:		src/sys
    515 Notes:		No longer active due to the lack of time. If you plan to
    516 		continue this branch, sys/netinet/in_pcb.h already contains
    517 		the proposed structure layout (which was roughly discussed
    518 		in the tech-net mailing list).
    519 		I also defined INP_*() macros to mimicate FreeBSD's inpcb
    520 		locking style, but currently they do nothing and are not
    521 		yet called at the correct places (needs discussion about
    522 		kernel fine-grained locking).
    523 		To continue this branch, one needs to read all the relevant
    524 		inpcb/in6pcb source files and change the function names,
    525 		structure names, structure fields according to the new
    526 		layout (in6pcb is gone).
    527 		Don't try to build a kernel from this branch because it won't
    528 		work. The missing pieces required to do a complete build
    529 		were not committed because they were incomplete and generated
    530 		panics.
    531 		You shouldn't need to worry about KAME syncs because
    532 		they did most of them by now.
    533 		After the work is done, you are required to test the branch
    534 		(before the merge to -current) with an interop IPv6 test.

    545 		or lib/libpthread or maybe gdb.
    546 Notes:		This branch is based off of the netbsd-4 branch!
    547 		This branch is intended to stage improvements for the
    548 		Scheduler Activations system for NetBSD 4. Improvements
    549 		include not allocating memory while preparing to tsleep(),
    550 		reducing inappropriate upcall delivery (hopefully also
    551 		eliminating the need to mlock stacks), and being
    552 		able to pthread_kill() running threads. At this date,
    553 		most goals have been achieved. This branch also includes
    554 		fixes to gdb to support working with threaded apps.

    564 Notes:		This branch is intended to revive Scheduler Activations
    565 		in -current in the 5.0 era. This branch's main goal is
    566 		to re-add syscall compatability so that SA-based libpthread
    567 		programs can run with a -current kernel. 1:1 threading will
    568 		remain the NetBSD-default. This branch will re-add necessary
    569 		upcall support, and will also serve as a chance to clean
    570 		out cruft that had accumulated in the implementation over
    571 		time.

    600 Branch:		reinoud-bufcleanup
    601 Description:	implement and evaluate struct buf usage cleanup strategies.
    602 		Ideas currently in mind (preference for b):
    603 		a)
    604 			1. use of bio_ops per buffer.
    605 			2. allow chaining/overloading of functions in bio_ops
    606 			   and provide some private context.
    607 			3. extend the bio_ops with commonly used functionality
    608 			   like pending action counting, custom context passing,
    609 			   last minute processing of buffer data, buffer cache
    610 			   etc.
    611 			4. investigate the use of the kcont()
    612 			   continuation-passing framework for async io
    613 			   completion notification for bufs
    614 			...
    615 		b)
    616 			1. all sequencing use of B_CALL replaced by
    617 			   device-threads, if possible generic code around BUFQ
    618 			2. possibly use kcont() for async IO finished signaling
    619 			3. counter of pending and queued actions requestable
    620 			   by IOCTL interface?
    621 			4. implement `last minute buffer fixup' calls and maybe
    622 			   even finished I/O calls as vnode operations
    623 			...

   1320 Notes:		No longer active due to lack of time, and introduction
   1321 		of UBC. In terms of UBC, the primary cache for
   1322 		file data is the VM cache, which needs to operate
   1323 		in terms of VM pages. As no existing device has native
   1324 		pages the same size as our VM pages, there already is
   1325 		a mapping going on between the VM system and the
   1326 		underlying blocks. So it would be easier and cleaner
   1327 		to adjust that to deal w/ different block sizes.
   1328 		Also with UBC, all i/o is in terms of bytes at an offset
   1329 		with a certain length, so the exact block size isn't a big
   1330 		deal.

   1368 		How to adapt a port?
   1369 
   1370 		- unify cpu_switch, cpu_exit, cpu_switchto into
   1371 		  a single cpu_switchto.  see cpu_switchto.9.
   1372 
   1373 		- implement cpu_idle.  see cpu_idle.9.
   1374 
   1375 		- add a flag argument to cpu_need_resched.
   1376 		  handle RESCHED_IMMED flag, which means "cause a preemption
   1377 		  as soon as possible."  eg. in the case of MULTIPROCESSOR,
   1378 		  send an IPI to the target cpu.
   1379 
   1380 		- "curlwp == NULL" is not a valid check for idle state anymore.
   1381 		  use "(curlwp->l_flag & LW_IDLE) != 0" instead.  curlwp is
   1382 		  almost always non-NULL, with exceptions like early on boot.
   1383 
   1384 		- remove idle pcbs.
   1385 
   1386 		- (if MULTIPROCESSOR) tweak processor trampoline code.
   1387 
   1388 		- (if MULTIPROCESSOR) call mi_cpu_attach when attaching
   1389 		  secondary processors.
   1390 
   1391 		- (if schedhz!=0) call schedclock regardless of the value of
   1392 		  curlwp.
   1393 
   1394 		- of course, update MD users of scheduler/switching API.

   1774 		TODO:
   1775 
   1776 		all		- Need to replace mb_*() with membar_*().
   1777 
   1778 				- Audit MUTEX_CAS() and RWLOCK_CAS() uses
   1779 				  to see of membar_enter() is required here.
   1780 
   1781 				- Talk to ad@ -- figure out of non-atomic
   1782 				  mutex / rwlock release is actually safe.
   1783 
   1784 		arm		- Consider using a RAS technique like
   1785 				  MIPS uses for _lock_cas() and the mutex
   1786 				  stubs.  Possibly do more than one atomic
   1787 				  op as a RAS.  Possibly implement mutex
   1788 				  stubs using the technique.
   1789 
   1790 		m68k		- Need to do 68010 support.
   1791 		
   1792 		i386		- Need to change when x86_patch() is called
   1793 				  so we can test ncpus.
   1794 
   1795 		powerpc		- Figure out if we need barriers in the
   1796 				  atomic ops themselves (hopefully not!)
   1797 
   1798 		x86_64		- Need to change when x86_patch() is called
   1799 				  so we can test ncpus.
