BRANCHES revision 1.338 1 # $NetBSD: BRANCHES,v 1.338 2017/03/15 06:17:39 snj Exp $

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.
34 #
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.

317 Branch: ad-audiomp
318 Description: Add MP locking to the audio drivers
319 Status: Terminated
320 Start Date: 28 February 2007
321 End Date: 7 December 2008
322 Base Tag: ad-audiomp-base
323 Maintainer: Andrew Doran <ad (a] NetBSD.org>
324 Scope: kernel
325 Notes: Making the audio drivers MP safe is necessary before efforts
326 can be made to make the VM system MP safe. About 1/2 of the
327 drivers are converted, the remaining 1/2 need more changes.
328
329 As of import this is snapshot of work in progress and so
330 may not compile; in particular the midi changes are very
331 much "in progress". The audio component has been tested
332 and verified to work with emuxki and auvia. There may
333 be a locking issue in the ac97 code at boot.
334
335 The are two locks per device instance, an ISR lock and
336 a character device lock. The ISR lock replaces calls to
337 splaudio()/splx(), and will be held across calls to device
338 methods which were called at splaudio() before (e.g.
339 trigger_output). The character device lock is held across
340 calls to nearly all of the methods, excluding some only
341 used for initialization, e.g. get_locks. This needs to be
342 documented at merge time.
343
344 To test on a multi way x86 system, search for "mpsafe" in
345 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job
346 that will acquire the ISR lock (depends on the hardware, but
347 "while true; do mixerctl -a > /dev/null; done" may suffice).
348 Play audio, run lockstat and verify that that there is
349 contention on the ISR lock.

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

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650 Notes: No longer active due to the lack of time.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

680 or lib/libpthread or maybe gdb.
681 Notes: This branch is based off of the netbsd-4 branch!
682 This branch is intended to stage improvements for the
683 Scheduler Activations system for NetBSD 4. Improvements
684 include not allocating memory while preparing to tsleep(),
685 reducing inappropriate upcall delivery (hopefully also
686 eliminating the need to mlock stacks), and being
687 able to pthread_kill() running threads. At this date,
688 most goals have been achieved. This branch also includes
689 fixes to gdb to support working with threaded apps.

699 Notes: This branch is intended to revive Scheduler Activations
700 in -current in the 5.0 era. This branch's main goal is
701 to re-add syscall compatability so that SA-based libpthread
702 programs can run with a -current kernel. 1:1 threading will
703 remain the NetBSD-default. This branch will re-add necessary
704 upcall support, and will also serve as a chance to clean
705 out cruft that had accumulated in the implementation over
706 time.

745 - reduce unnecessary page scan in putpages. esp. when an
746 object has a ton of pages cached but only a few of them
747 are dirty.
748 - reduce the number of pmap operations by tracking page
749 dirtiness more precisely in uvm layer.
750 - fix nfs commit range tracking.
751 - fix nfs write clustering. XXX hack
752 - fix A->O loaning

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

1348 Based on the patch from ad@.
1349 - Simplify locking in pmap(9) modules by removing P->V locking.
1350 - Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock)
1351 to share locks among UVM objects where necessary.
1352 - Rewrite and optimize x86 TLB shootdown code.
1353 - Unify /dev/mem et al in MI code and provide required locking.

1370
1371 Not guaranteed to compile against mainline since -current
1372 may have changed incompatibly with the last branch update;

1381 Note that this branch uses a DIFFERENT scheme for
1382 syncing with the mainline. the maintainer uses some private
1383 scripts for keeping them in sync; if you make commits
1384 to the branch to "resynchronize" things, you'll
1385 probably do it wrong; instead, ask the maintainer to
1386 resynchronize things.

1521 - Removing large files (sparse only?) takes a long time.
1522 Eg, a file created with
1523 dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550
1524 takes 0:00.00 to remove on my test box without logging and
1525 0:22.25 to remove with logging. No disk IO during this...

1621 Notes: No longer active due to lack of time, and introduction
1622 of UBC. In terms of UBC, the primary cache for
1623 file data is the VM cache, which needs to operate
1624 in terms of VM pages. As no existing device has native
1625 pages the same size as our VM pages, there already is
1626 a mapping going on between the VM system and the
1627 underlying blocks. So it would be easier and cleaner
1628 to adjust that to deal w/ different block sizes.
1629 Also with UBC, all i/o is in terms of bytes at an offset
1630 with a certain length, so the exact block size isn't a big
1631 deal.

1633 Any other wrstuden-devbsize tag may (and should) go away.

1669 How to adapt a port?
1670
1671 - unify cpu_switch, cpu_exit, cpu_switchto into
1672 a single cpu_switchto. see cpu_switchto.9.
1673
1674 - implement cpu_idle. see cpu_idle.9.
1675
1676 - add a flag argument to cpu_need_resched.
1677 handle RESCHED_IMMED flag, which means "cause a preemption
1678 as soon as possible." eg. in the case of MULTIPROCESSOR,
1679 send an IPI to the target cpu.
1680
1681 - "curlwp == NULL" is not a valid check for idle state anymore.
1682 use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1683 almost always non-NULL, with exceptions like early on boot.
1684
1685 - remove idle pcbs.
1686
1687 - (if MULTIPROCESSOR) tweak processor trampoline code.
1688
1689 - (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1690 secondary processors.
1691
1692 - (if schedhz!=0) call schedclock regardless of the value of
1693 curlwp.
1694
1695 - of course, update MD users of scheduler/switching API.
