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,

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

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

256 Branch: ad-audiomp2
257 Description: Add MP locking to the audio drivers

266 Branch: bjh21-hydra

268 Status: Dormant
269 Start Date: 18 Oct 2002
270 End Date:
271 Base Tag: bjh21-hydra-base
272 Maintainer: Ben Harris <bjh21 (a] NetBSD.org>
273 Scope: sys/arch/arm sys/arch/acorn32
274 Notes: This code was on a branch because it involves changes to
275 cpuswitch.S which would otherwise make merging the
276 nathanw_sa branch difficult.
277
278 Branch: chris-arm-intr-rework

284 Maintainer: Chris Gilbert <chris (a] NetBSD.org>
285 Scope: sys/arch/arm sys/arch/cats (other arm archs to follow)
286 Notes: Rework arm interrupt code to provide a shared set of interrupt
287 routines, and allow improvements to be shared across all arm
288 based hardware.
289
290 Branch: cube-autoconf

300 Branch: gmcgarry_ctxsw
301 Description: Separate scheduler from context-switch code
302 Status: Dormant
303 Start Date: 18 December 2002
304 End Date:
305 Base Tag: gmcgarry_ctxsw_base
306 Maintainer: Gregory McGarry <gmcgarry (a] NetBSD.org>
307 Scope: kernel
308 Notes: Removing knowledge of the scheduler and its run queues
309 from the machine-dependent context switch code is the
310 first step in cleaning up the scheduler. It is necessary
311 for the newlock branch, making the scheduler SMP friendly,
312 adding real-time scheduler extensions, and reducing the
313 number of code paths for LWP and proc switching.
314

484 End Date:
485 Base Tag: rpaulo-netinet-merge-pcb-base
486 Maintainer: Rui Paulo <rpaulo (a] NetBSD.org>
487 Scope: src/sys
488 Notes: No longer active due to the lack of time. If you plan to
489 continue this branch, sys/netinet/in_pcb.h already contains
490 the proposed structure layout (which was roughly discussed
491 in the tech-net mailing list).
492 I also defined INP_*() macros to mimicate FreeBSD's inpcb
493 locking style, but currently they do nothing and are not
494 yet called at the correct places (needs discussion about
495 kernel fine-grained locking).
496 To continue this branch, one needs to read all the relevant
497 inpcb/in6pcb source files and change the function names,
498 structure names, structure fields according to the new
499 layout (in6pcb is gone).
500 Don't try to build a kernel from this branch because it won't
501 work. The missing pieces required to do a complete build
502 were not committed because they were incomplete and generated
503 panics.
504 You shouldn't need to worry about KAME syncs because
505 they did most of them by now.
506 After the work is done, you are required to test the branch
507 (before the merge to -current) with an interop IPv6 test.

526 Branch: wrstuden-fixsa
527 Description: Fix a number of issues present with Scheduler Activations.
528 Status: Active

533 Scope: src, though all the interesting stuff is in the kernel
534 or lib/libpthread or maybe gdb.
535 Notes: This branch is based off of the netbsd-4 branch!
536 This branch is intended to stage improvements for the
537 Scheduler Activations system for NetBSD 4. Improvements
538 include not allocating memory while preparing to tsleep(),
539 reducing inappropriate upcall delivery (hopefully also
540 eliminating the need to mlock stacks), and being
541 able to pthread_kill() running threads. At this date,
542 most goals have been achieved. This branch also includes
543 fixes to gdb to support working with threaded apps.

551 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org>
552 Scope: src, though all the interesting stuff is in the kernel
553 Notes: This branch is intended to revive Scheduler Activations
554 in -current in the 5.0 era. This branch's main goal is
555 to re-add syscall compatability so that SA-based libpthread
556 programs can run with a -current kernel. 1:1 threading will
557 remain the NetBSD-default. This branch will re-add necessary
558 upcall support, and will also serve as a chance to clean
559 out cruft that had accumulated in the implementation over

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

675
676 - Talk to ad@ -- figure out of non-atomic
677 mutex / rwlock release is actually safe.
678
679 arm - Consider using a RAS technique like
680 MIPS uses for _lock_cas() and the mutex
681 stubs. Possibly do more than one atomic
682 op as a RAS. Possibly implement mutex
683 stubs using the technique.
684
685 m68k - Need to do 68010 support.
686
687 i386 - Need to change when x86_patch() is called
688 so we can test ncpus.

691 atomic ops themselves (hopefully not!)

1119 Notes:
1120 Code committed to the branch has booted to multiuser
1121 on at least one system.
1122
1123 Not guaranteed to compile against mainline since -current
1124 may have changed incompatibly with the last branch update;
1125 use "cvs update -D" to roll-back the rest of the tree to match.
1126
1127 Please get explicit permission from the maintainer
1128 before each commit, or your changes will be backed out.
1129 Other tags starting with sommerfeld_ are private to
1130 the developer and are guaranteed to be unstable.
1131 Only the maintainer should move tags.
1132
1133 Note that this branch uses a DIFFERENT scheme for
1134 syncing with the mainline. the maintainer uses some private
1135 scripts for keeping them in sync; if you make commits
1136 to the branch to "resynchronize" things, you'll
1137 probably do it wrong; instead, ask the maintainer to
1138 resynchronize things.

1269 Notes: Still has a number of issues:
1270 - Some heavy workload performance issues on SMP machines.
1271 Work around this issue by turning on WAPBL_DEBUG_SERIALIZE
1272 in rev 1.1.2.11 of vfs_wapbl.c.
1273 - Removing large files (sparse only?) takes a long time.
1274 Eg, a file created with
1275 dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550
1276 takes 0:00.00 to remove on my test box without logging and
1277 0:22.25 to remove with logging. No disk IO during this...
1278 - sysinst should use in-fs logs now, not end-of-partition logs.

1333 Base tag: wrstuden-devbsize-base
1334 Maintainer: Bill Studenmund <wrstuden (a] NetBSD.org>
1335 Scope: kernel
1336 Notes: No longer active due to lack of time, and introduction
1337 of UBC. In terms of UBC, the primary cache for
1338 file data is the VM cache, which needs to operate
1339 in terms of VM pages. As no existing device has native
1340 pages the same size as our VM pages, there already is
1341 a mapping going on between the VM system and the
1342 underlying blocks. So it would be easier and cleaner
1343 to adjust that to deal w/ different block sizes.
1344 Also with UBC, all i/o is in terms of bytes at an offset
1345 with a certain length, so the exact block size isn't a big
1346 deal.
1347
1348 Any other wrstuden-devbsize tag may (and should) go away.

1384 How to adapt a port?
1385
1386 - unify cpu_switch, cpu_exit, cpu_switchto into
1387 a single cpu_switchto. see cpu_switchto.9.
1388
1389 - implement cpu_idle. see cpu_idle.9.
1390
1391 - add a flag argument to cpu_need_resched.
1392 handle RESCHED_IMMED flag, which means "cause a preemption
1393 as soon as possible." eg. in the case of MULTIPROCESSOR,
1394 send an IPI to the target cpu.
1395
1396 - "curlwp == NULL" is not a valid check for idle state anymore.
1397 use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1398 almost always non-NULL, with exceptions like early on boot.
1399
1400 - remove idle pcbs.
1401
1402 - (if MULTIPROCESSOR) tweak processor trampoline code.
1403
1404 - (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1405 secondary processors.
1406
1407 - (if schedhz!=0) call schedclock regardless of the value of
1408 curlwp.
1409
1410 - of course, update MD users of scheduler/switching API.
