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.

35 # There are four sections to this file:
36 # Release branches
37 # Individual developers' branches (Active/Dormant)
38 # Individual developers' branches (Terminated), and
39 # other
40 #
41 # Entries within each section should be alphabetized.

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.

690 Scope: src, though all the interesting stuff is in the kernel
691 or lib/libpthread or maybe gdb.
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.

756 - reduce unnecessary page scan in putpages. esp. when an
757 object has a ton of pages cached but only a few of them
758 are dirty.
759 - reduce the number of pmap operations by tracking page
760 dirtiness more precisely in uvm layer.
761 - fix nfs commit range tracking.
762 - fix nfs write clustering. XXX hack
763 - fix A->O loaning

857 Branch: reinoud-bufcleanup
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 ...

1373 - Reorganize locking in UVM and serialize pmap(9) operations
1374 on same page(s). New lock order: [vmpage-lock] -> pmap-lock.
1375 Based on the patch from ad@.
1376 - Simplify locking in pmap(9) modules by removing P->V locking.
1377 - Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock)
1378 to share locks among UVM objects where necessary.
1379 - Rewrite and optimize x86 TLB shootdown code.
1380 - Unify /dev/mem et al in MI code and provide required locking.
1381
1382 Future work:
1383
1384 - Optimize pmap_remove() with tracking in struct vm_map_entry.

1397
1398 Not guaranteed to compile against mainline since -current
1399 may have changed incompatibly with the last branch update;
1400 use "cvs update -D" to roll-back the rest of the tree to match.
1401
1402 Please get explicit permission from the maintainer
1403 before each commit, or your changes will be backed out.
1404 Other tags starting with sommerfeld_ are private to
1405 the developer and are guaranteed to be unstable.

1408 Note that this branch uses a DIFFERENT scheme for
1409 syncing with the mainline. the maintainer uses some private
1410 scripts for keeping them in sync; if you make commits
1411 to the branch to "resynchronize" things, you'll
1412 probably do it wrong; instead, ask the maintainer to
1413 resynchronize things.

1548 - Removing large files (sparse only?) takes a long time.
1549 Eg, a file created with
1550 dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550
1551 takes 0:00.00 to remove on my test box without logging and
1552 0:22.25 to remove with logging. No disk IO during this...

1641 different block sizes. Also DEV_BSIZE would go away.

1646 Maintainer: Bill Studenmund <wrstuden (a] NetBSD.org>
1647 Scope: kernel
1648 Notes: No longer active due to lack of time, and introduction
1649 of UBC. In terms of UBC, the primary cache for
1650 file data is the VM cache, which needs to operate
1651 in terms of VM pages. As no existing device has native
1652 pages the same size as our VM pages, there already is
1653 a mapping going on between the VM system and the
1654 underlying blocks. So it would be easier and cleaner
1655 to adjust that to deal w/ different block sizes.
1656 Also with UBC, all i/o is in terms of bytes at an offset
1657 with a certain length, so the exact block size isn't a big
1658 deal.
1659
1660 Any other wrstuden-devbsize tag may (and should) go away.

1696 How to adapt a port?
1697
1698 - unify cpu_switch, cpu_exit, cpu_switchto into
1699 a single cpu_switchto. see cpu_switchto.9.
1700
1701 - implement cpu_idle. see cpu_idle.9.
1702
1703 - add a flag argument to cpu_need_resched.
1704 handle RESCHED_IMMED flag, which means "cause a preemption
1705 as soon as possible." eg. in the case of MULTIPROCESSOR,
1706 send an IPI to the target cpu.
1707
1708 - "curlwp == NULL" is not a valid check for idle state anymore.
1709 use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1710 almost always non-NULL, with exceptions like early on boot.
1711
1712 - remove idle pcbs.
1713
1714 - (if MULTIPROCESSOR) tweak processor trampoline code.
1715
1716 - (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1717 secondary processors.
1718
1719 - (if schedhz!=0) call schedclock regardless of the value of
1720 curlwp.
1721
1722 - of course, update MD users of scheduler/switching API.
