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.

296 Branch: ad-audiomp
297 Description: Add MP locking to the audio drivers
298 Status: Terminated
299 Start Date: 28 February 2007
300 End Date: 7 December 2008
301 Base Tag: ad-audiomp-base
302 Maintainer: Andrew Doran <ad (a] NetBSD.org>
303 Scope: kernel
304 Notes: Making the audio drivers MP safe is necessary before efforts
305 can be made to make the VM system MP safe. About 1/2 of the
306 drivers are converted, the remaining 1/2 need more changes.
307
308 As of import this is snapshot of work in progress and so
309 may not compile; in particular the midi changes are very
310 much "in progress". The audio component has been tested
311 and verified to work with emuxki and auvia. There may
312 be a locking issue in the ac97 code at boot.
313
314 The are two locks per device instance, an ISR lock and
315 a character device lock. The ISR lock replaces calls to
316 splaudio()/splx(), and will be held across calls to device
317 methods which were called at splaudio() before (e.g.
318 trigger_output). The character device lock is held across
319 calls to nearly all of the methods, excluding some only
320 used for initialization, e.g. get_locks. This needs to be
321 documented at merge time.
322
323 To test on a multi way x86 system, search for "mpsafe" in
324 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job
325 that will acquire the ISR lock (depends on the hardware, but
326 "while true; do mixerctl -a > /dev/null; done" may suffice).
327 Play audio, run lockstat and verify that that there is
328 contention on the ISR lock.

607 - Rework IPv4, UDP and ICMP paths to be MP safe.
608 - Switch UDP sockets to a separate lock, test and benchmark.

614 End Date:
615 Base Tag: rpaulo-netinet-merge-pcb-base
616 Maintainer: Rui Paulo <rpaulo (a] NetBSD.org>
617 Scope: src/sys
618 Notes: No longer active due to the lack of time. If you plan to
619 continue this branch, sys/netinet/in_pcb.h already contains
620 the proposed structure layout (which was roughly discussed
621 in the tech-net mailing list).
622 I also defined INP_*() macros to mimicate FreeBSD's inpcb
623 locking style, but currently they do nothing and are not
624 yet called at the correct places (needs discussion about
625 kernel fine-grained locking).
626 To continue this branch, one needs to read all the relevant
627 inpcb/in6pcb source files and change the function names,
628 structure names, structure fields according to the new
629 layout (in6pcb is gone).
630 Don't try to build a kernel from this branch because it won't
631 work. The missing pieces required to do a complete build
632 were not committed because they were incomplete and generated
633 panics.
634 You shouldn't need to worry about KAME syncs because
635 they did most of them by now.
636 After the work is done, you are required to test the branch
637 (before the merge to -current) with an interop IPv6 test.

640 Branch: wrstuden-fixsa

642 Status: Active

644 End Date:
645 Base Tag: wrstuden-fixsa-base
646 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org>
647 Scope: src, though all the interesting stuff is in the kernel
648 or lib/libpthread or maybe gdb.
649 Notes: This branch is based off of the netbsd-4 branch!
650 This branch is intended to stage improvements for the
651 Scheduler Activations system for NetBSD 4. Improvements
652 include not allocating memory while preparing to tsleep(),
653 reducing inappropriate upcall delivery (hopefully also
654 eliminating the need to mlock stacks), and being
655 able to pthread_kill() running threads. At this date,
656 most goals have been achieved. This branch also includes
657 fixes to gdb to support working with threaded apps.

667 Notes: This branch is intended to revive Scheduler Activations
668 in -current in the 5.0 era. This branch's main goal is
669 to re-add syscall compatability so that SA-based libpthread
670 programs can run with a -current kernel. 1:1 threading will
671 remain the NetBSD-default. This branch will re-add necessary
672 upcall support, and will also serve as a chance to clean
673 out cruft that had accumulated in the implementation over
674 time.

711 Notes: - maintain object pages in radix tree rather than rb tree.
712 - shrink the size of vm_page.
713 - reduce unnecessary page scan in putpages. esp. when an
714 object has a ton of pages cached but only a few of them
715 are dirty.
716 - reduce the number of pmap operations by tracking page
717 dirtiness more precisely in uvm layer.
718 - fix nfs commit range tracking.
719 - fix nfs write clustering. XXX hack
720 - fix A->O loaning
721 - write radixtree(9) man page

814 Branch: reinoud-bufcleanup
815 Description: implement and evaluate struct buf usage cleanup strategies.
816 Ideas currently in mind (preference for b):
817 a)
818 1. use of bio_ops per buffer.
819 2. allow chaining/overloading of functions in bio_ops
820 and provide some private context.
821 3. extend the bio_ops with commonly used functionality
822 like pending action counting, custom context passing,
823 last minute processing of buffer data, buffer cache
824 etc.
825 4. investigate the use of the kcont()
826 continuation-passing framework for async io
827 completion notification for bufs
828 ...
829 b)
830 1. all sequencing use of B_CALL replaced by
831 device-threads, if possible generic code around BUFQ
832 2. possibly use kcont() for async IO finished signaling
833 3. counter of pending and queued actions requestable
834 by IOCTL interface?
835 4. implement `last minute buffer fixup' calls and maybe
836 even finished I/O calls as vnode operations
837 ...

1305 - Simplify locking in pmap(9) modules by removing P->V locking.
1306 - Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock)
1307 to share locks among UVM objects where necessary.
1308 - Rewrite and optimize x86 TLB shootdown code.
1309 - Unify /dev/mem et al in MI code and provide required locking.

1326

1341 probably do it wrong; instead, ask the maintainer to
1342 resynchronize things.

1477 - Removing large files (sparse only?) takes a long time.
1478 Eg, a file created with
1479 dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550
1480 takes 0:00.00 to remove on my test box without logging and
1481 0:22.25 to remove with logging. No disk IO during this...

1576 Scope: kernel
1577 Notes: No longer active due to lack of time, and introduction
1578 of UBC. In terms of UBC, the primary cache for
1579 file data is the VM cache, which needs to operate
1580 in terms of VM pages. As no existing device has native
1581 pages the same size as our VM pages, there already is
1582 a mapping going on between the VM system and the
1583 underlying blocks. So it would be easier and cleaner
1584 to adjust that to deal w/ different block sizes.
1585 Also with UBC, all i/o is in terms of bytes at an offset
1586 with a certain length, so the exact block size isn't a big
1587 deal.

1630 - implement cpu_idle. see cpu_idle.9.
1631
1632 - add a flag argument to cpu_need_resched.
1633 handle RESCHED_IMMED flag, which means "cause a preemption
1634 as soon as possible." eg. in the case of MULTIPROCESSOR,
1635 send an IPI to the target cpu.
1636
1637 - "curlwp == NULL" is not a valid check for idle state anymore.
1638 use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1639 almost always non-NULL, with exceptions like early on boot.
1640
1641 - remove idle pcbs.
1642
1643 - (if MULTIPROCESSOR) tweak processor trampoline code.
1644
1645 - (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1646 secondary processors.
1647
1648 - (if schedhz!=0) call schedclock regardless of the value of
1649 curlwp.
1650
1651 - of course, update MD users of scheduler/switching API.
