BRANCHES revision 1.323 1 # $NetBSD: BRANCHES,v 1.323 2012/05/06 07:28:48 agc Exp $
2 #
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.

243 Branch: ad-audiomp
244 Description: Add MP locking to the audio drivers
245 Status: Terminated
246 Start Date: 28 February 2007
247 End Date: 7 December 2008
248 Base Tag: ad-audiomp-base
249 Maintainer: Andrew Doran <ad (a] NetBSD.org>
250 Scope: kernel
251 Notes: Making the audio drivers MP safe is necessary before efforts
252 can be made to make the VM system MP safe. About 1/2 of the
253 drivers are converted, the remaining 1/2 need more changes.
254
255 As of import this is snapshot of work in progress and so
256 may not compile; in particular the midi changes are very
257 much "in progress". The audio component has been tested
258 and verified to work with emuxki and auvia. There may
259 be a locking issue in the ac97 code at boot.
260
261 The are two locks per device instance, an ISR lock and
262 a character device lock. The ISR lock replaces calls to
263 splaudio()/splx(), and will be held across calls to device
264 methods which were called at splaudio() before (e.g.
265 trigger_output). The character device lock is held across
266 calls to nearly all of the methods, excluding some only
267 used for initialization, e.g. get_locks. This needs to be
268 documented at merge time.
269
270 To test on a multi way x86 system, search for "mpsafe" in
271 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job
272 that will acquire the ISR lock (depends on the hardware, but
273 "while true; do mixerctl -a > /dev/null; done" may suffice).
274 Play audio, run lockstat and verify that that there is
275 contention on the ISR lock.

277 Branch: ad-audiomp2
278 Description: Add MP locking to the audio drivers

295 Notes: This branch is used to develop the version of netpgp
296 which has its own version of bignum, ciphers, and signatures
297 libraries, so that it is able to operate without openssl
298 being in place.

524 Status: Dormant
525 Start Date: Wed Feb 01 2006
526 End Date:
527 Base Tag: rpaulo-netinet-merge-pcb-base
528 Maintainer: Rui Paulo <rpaulo (a] NetBSD.org>
529 Scope: src/sys
530 Notes: No longer active due to the lack of time. If you plan to
531 continue this branch, sys/netinet/in_pcb.h already contains
532 the proposed structure layout (which was roughly discussed
533 in the tech-net mailing list).
534 I also defined INP_*() macros to mimicate FreeBSD's inpcb
535 locking style, but currently they do nothing and are not
536 yet called at the correct places (needs discussion about
537 kernel fine-grained locking).
538 To continue this branch, one needs to read all the relevant
539 inpcb/in6pcb source files and change the function names,
540 structure names, structure fields according to the new
541 layout (in6pcb is gone).
542 Don't try to build a kernel from this branch because it won't
543 work. The missing pieces required to do a complete build
544 were not committed because they were incomplete and generated
545 panics.
546 You shouldn't need to worry about KAME syncs because
547 they did most of them by now.
548 After the work is done, you are required to test the branch
549 (before the merge to -current) with an interop IPv6 test.

563 Scheduler Activations system for NetBSD 4. Improvements
564 include not allocating memory while preparing to tsleep(),
565 reducing inappropriate upcall delivery (hopefully also
566 eliminating the need to mlock stacks), and being
567 able to pthread_kill() running threads. At this date,
568 most goals have been achieved. This branch also includes
569 fixes to gdb to support working with threaded apps.

571 Branch: wrstuden-revivesa
572 Description: Fix a number of issues present with Scheduler Activations.
573 Status: Active

576 Base Tag: wrstuden-revivesa-base
577 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org>
578 Scope: src, though all the interesting stuff is in the kernel
579 Notes: This branch is intended to revive Scheduler Activations
580 in -current in the 5.0 era. This branch's main goal is
581 to re-add syscall compatability so that SA-based libpthread
582 programs can run with a -current kernel. 1:1 threading will
583 remain the NetBSD-default. This branch will re-add necessary
584 upcall support, and will also serve as a chance to clean
585 out cruft that had accumulated in the implementation over
586 time.

601 with vmem_xalloc. find a tester with hardware for it.
602 - g/c replaced code, including kmapent and malloc.

623 Notes: - maintain object pages in radix tree rather than rb tree.
624 - shrink the size of vm_page.
625 - reduce unnecessary page scan in putpages. esp. when an
626 object has a ton of pages cached but only a few of them
627 are dirty.
628 - reduce the number of pmap operations by tracking page
629 dirtiness more precisely in uvm layer.
630 - fix nfs commit range tracking.
631 - fix nfs write clustering. XXX hack
632
633 TODO:
634 - benchmark
635 - test
636 - make the write clustering fix less kludgy
637 - fix or disable the ad-hoc per-cpu statistic

723 Branch: reinoud-bufcleanup
724 Description: implement and evaluate struct buf usage cleanup strategies.
725 Ideas currently in mind (preference for b):
726 a)
727 1. use of bio_ops per buffer.
728 2. allow chaining/overloading of functions in bio_ops
729 and provide some private context.
730 3. extend the bio_ops with commonly used functionality
731 like pending action counting, custom context passing,
732 last minute processing of buffer data, buffer cache
733 etc.
734 4. investigate the use of the kcont()
735 continuation-passing framework for async io
736 completion notification for bufs
737 ...
738 b)
739 1. all sequencing use of B_CALL replaced by
740 device-threads, if possible generic code around BUFQ
741 2. possibly use kcont() for async IO finished signaling
742 3. counter of pending and queued actions requestable
743 by IOCTL interface?
744 4. implement `last minute buffer fixup' calls and maybe
745 even finished I/O calls as vnode operations
746 ...

1213 Based on the patch from ad@.
1214 - Simplify locking in pmap(9) modules by removing P->V locking.
1215 - Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock)
1216 to share locks among UVM objects where necessary.
1217 - Rewrite and optimize x86 TLB shootdown code.
1218 - Unify /dev/mem et al in MI code and provide required locking.

1235
1236 Not guaranteed to compile against mainline since -current
1237 may have changed incompatibly with the last branch update;
1238 use "cvs update -D" to roll-back the rest of the tree to match.
1239
1240 Please get explicit permission from the maintainer
1241 before each commit, or your changes will be backed out.
1242 Other tags starting with sommerfeld_ are private to
1243 the developer and are guaranteed to be unstable.
1244 Only the maintainer should move tags.

1246 Note that this branch uses a DIFFERENT scheme for
1247 syncing with the mainline. the maintainer uses some private
1248 scripts for keeping them in sync; if you make commits
1249 to the branch to "resynchronize" things, you'll
1250 probably do it wrong; instead, ask the maintainer to
1251 resynchronize things.

1386 - Removing large files (sparse only?) takes a long time.
1387 Eg, a file created with
1388 dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550
1389 takes 0:00.00 to remove on my test box without logging and
1390 0:22.25 to remove with logging. No disk IO during this...

1484 Maintainer: Bill Studenmund <wrstuden (a] NetBSD.org>
1485 Scope: kernel
1486 Notes: No longer active due to lack of time, and introduction
1487 of UBC. In terms of UBC, the primary cache for
1488 file data is the VM cache, which needs to operate
1489 in terms of VM pages. As no existing device has native
1490 pages the same size as our VM pages, there already is
1491 a mapping going on between the VM system and the
1492 underlying blocks. So it would be easier and cleaner
1493 to adjust that to deal w/ different block sizes.
1494 Also with UBC, all i/o is in terms of bytes at an offset
1495 with a certain length, so the exact block size isn't a big
1496 deal.

1534 How to adapt a port?
1535
1536 - unify cpu_switch, cpu_exit, cpu_switchto into
1537 a single cpu_switchto. see cpu_switchto.9.
1538
1539 - implement cpu_idle. see cpu_idle.9.
1540
1541 - add a flag argument to cpu_need_resched.
1542 handle RESCHED_IMMED flag, which means "cause a preemption
1543 as soon as possible." eg. in the case of MULTIPROCESSOR,
1544 send an IPI to the target cpu.
1545
1546 - "curlwp == NULL" is not a valid check for idle state anymore.
1547 use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1548 almost always non-NULL, with exceptions like early on boot.
1549
1550 - remove idle pcbs.
1551
1552 - (if MULTIPROCESSOR) tweak processor trampoline code.
1553
1554 - (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1555 secondary processors.
1556
1557 - (if schedhz!=0) call schedclock regardless of the value of
1558 curlwp.
1559
1560 - of course, update MD users of scheduler/switching API.

1877 first step in cleaning up the scheduler. It is necessary
1878 for the newlock branch, making the scheduler SMP friendly,
1879 adding real-time scheduler extensions, and reducing the
1880 number of code paths for LWP and proc switching.

1942 all - Need to replace mb_*() with membar_*().
1943
1944 - Audit MUTEX_CAS() and RWLOCK_CAS() uses
1945 to see of membar_enter() is required here.
1946
1947 - Talk to ad@ -- figure out of non-atomic
1948 mutex / rwlock release is actually safe.
1949
1950 arm - Consider using a RAS technique like
1951 MIPS uses for _lock_cas() and the mutex
1952 stubs. Possibly do more than one atomic
1953 op as a RAS. Possibly implement mutex
1954 stubs using the technique.
1955
1956 m68k - Need to do 68010 support.
1957
1958 i386 - Need to change when x86_patch() is called
1959 so we can test ncpus.
1960
1961 powerpc - Figure out if we need barriers in the
1962 atomic ops themselves (hopefully not!)
1963
1964 x86_64 - Need to change when x86_patch() is called
1965 so we can test ncpus.
