BRANCHES revision 1.268 1 # $NetBSD: BRANCHES,v 1.268 2008/08/30 18:33:47 tsutsui 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.
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.

211 Branch: ad-audiomp
212 Description: Add MP locking to the audio drivers
213 Status: Active
214 Start Date: 28 February 2007
215 End Date:
216 Base Tag: ad-audiomp-base
217 Maintainer: Andrew Doran <ad (a] NetBSD.org>
218 Scope: kernel
219 Notes: Making the audio drivers MP safe is necessary before efforts
220 can be made to make the VM system MP safe. About 1/2 of the
221 drivers are converted, the remaining 1/2 need more changes.
222
223 As of import this is snapshot of work in progress and so
224 may not compile; in particular the midi changes are very
225 much "in progress". The audio component has been tested
226 and verified to work with emuxki and auvia. There may
227 be a locking issue in the ac97 code at boot.
228
229 The are two locks per device instance, an ISR lock and
230 a character device lock. The ISR lock replaces calls to
231 splaudio()/splx(), and will be held across calls to device
232 methods which were called at splaudio() before (e.g.
233 trigger_output). The character device lock is held across
234 calls to nearly all of the methods, excluding some only
235 used for initialization, e.g. get_locks. This needs to be
236 documented at merge time.
237
238 To test on a multi way x86 system, search for "mpsafe" in
239 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job
240 that will acquire the ISR lock (depends on the hardware, but
241 "while true; do mixerctl -a > /dev/null; done" may suffice).
242 Play audio, run lockstat and verify that that there is
243 contention on the ISR lock.
244
245 Branch: bjh21-hydra
246 Description: Simtec Hydra support and ARM SMP in general
247 Status: Dormant
248 Start Date: 18 Oct 2002
249 End Date:
250 Base Tag: bjh21-hydra-base
251 Maintainer: Ben Harris <bjh21 (a] NetBSD.org>
252 Scope: sys/arch/arm sys/arch/acorn32
253 Notes: This code was on a branch because it involves changes to
254 cpuswitch.S which would otherwise make merging the
255 nathanw_sa branch difficult.
256
257 Branch: chris-arm-intr-rework
258 Description: Rework arm interrupt handling code
259 Status: Active
260 Start Date: 11 Aug 2007
261 End Date:
262 Base Tag: chris-arm-intr-rework-base
263 Maintainer: Chris Gilbert <chris (a] NetBSD.org>
264 Scope: sys/arch/arm sys/arch/cats (other arm archs to follow)
265 Notes: Rework arm interrupt code to provide a shared set of interrupt
266 routines, and allow improvements to be shared across all arm
267 based hardware.

279 Branch: gmcgarry_ctxsw
280 Description: Separate scheduler from context-switch code
281 Status: Dormant
282 Start Date: 18 December 2002
283 End Date:
284 Base Tag: gmcgarry_ctxsw_base
285 Maintainer: Gregory McGarry <gmcgarry (a] NetBSD.org>
286 Scope: kernel
287 Notes: Removing knowledge of the scheduler and its run queues
288 from the machine-dependent context switch code is the
289 first step in cleaning up the scheduler. It is necessary
290 for the newlock branch, making the scheduler SMP friendly,
291 adding real-time scheduler extensions, and reducing the
292 number of code paths for LWP and proc switching.

449 Status: Dormant
450 Start Date: Wed Feb 01 2006
451 End Date:
452 Base Tag: rpaulo-netinet-merge-pcb-base
453 Maintainer: Rui Paulo <rpaulo (a] NetBSD.org>
454 Scope: src/sys
455 Notes: No longer active due to the lack of time. If you plan to
456 continue this branch, sys/netinet/in_pcb.h already contains
457 the proposed structure layout (which was roughly discussed
458 in the tech-net mailing list).
459 I also defined INP_*() macros to mimicate FreeBSD's inpcb
460 locking style, but currently they do nothing and are not
461 yet called at the correct places (needs discussion about
462 kernel fine-grained locking).
463 To continue this branch, one needs to read all the relevant
464 inpcb/in6pcb source files and change the function names,
465 structure names, structure fields according to the new
466 layout (in6pcb is gone).
467 Don't try to build a kernel from this branch because it won't
468 work. The missing pieces required to do a complete build
469 were not committed because they were incomplete and generated
470 panics.
471 You shouldn't need to worry about KAME syncs because
472 they did most of them by now.
473 After the work is done, you are required to test the branch
474 (before the merge to -current) with an interop IPv6 test.

495 Status: Active
496 Start Date: 15 May 2007
497 End Date:
498 Base Tag: wrstuden-fixsa-base
499 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org>
500 Scope: src, though all the interesting stuff is in the kernel
501 or lib/libpthread or maybe gdb.
502 Notes: This branch is based off of the netbsd-4 branch!
503 This branch is intended to stage improvements for the
504 Scheduler Activations system for NetBSD 4. Improvements
505 include not allocating memory while preparing to tsleep(),
506 reducing inappropriate upcall delivery (hopefully also
507 eliminating the need to mlock stacks), and being
508 able to pthread_kill() running threads. At this date,
509 most goals have been achieved. This branch also includes
510 fixes to gdb to support working with threaded apps.

518 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org>
519 Scope: src, though all the interesting stuff is in the kernel
520 Notes: This branch is intended to revive Scheduler Activations
521 in -current in the 5.0 era. This branch's main goal is
522 to re-add syscall compatability so that SA-based libpthread
523 programs can run with a -current kernel. 1:1 threading will
524 remain the NetBSD-default. This branch will re-add necessary
525 upcall support, and will also serve as a chance to clean
526 out cruft that had accumulated in the implementation over
527 time.

557 Description: implement and evaluate struct buf usage cleanup strategies.
558 Ideas currently in mind (preference for b):
559 a)
560 1. use of bio_ops per buffer.
561 2. allow chaining/overloading of functions in bio_ops
562 and provide some private context.

564 like pending action counting, custom context passing,
565 last minute processing of buffer data, buffer cache
566 etc.

572 1. all sequencing use of B_CALL replaced by
573 device-threads, if possible generic code around BUFQ
574 2. possibly use kcont() for async IO finished signaling
575 3. counter of pending and queued actions requestable
576 by IOCTL interface?

641 to see of membar_enter() is required here.
642
643 - Talk to ad@ -- figure out of non-atomic
644 mutex / rwlock release is actually safe.
645
646 arm - Consider using a RAS technique like
647 MIPS uses for _lock_cas() and the mutex
648 stubs. Possibly do more than one atomic
649 op as a RAS. Possibly implement mutex
650 stubs using the technique.
651
652 m68k - Need to do 68010 support.
653
654 i386 - Need to change when x86_patch() is called
655 so we can test ncpus.
656
657 powerpc - Figure out if we need barriers in the
658 atomic ops themselves (hopefully not!)
659
660 x86_64 - Need to change when x86_patch() is called
661 so we can test ncpus.

1224 Notes: Still has a number of issues:
1225 - Some heavy workload performance issues on SMP machines.
1226 Work around this issue by turning on WAPBL_DEBUG_SERIALIZE
1227 in rev 1.1.2.11 of vfs_wapbl.c.
1228 - Removing large files (sparse only?) takes a long time.
1229 Eg, a file created with
1230 dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550
1231 takes 0:00.00 to remove on my test box without logging and
1232 0:22.25 to remove with logging. No disk IO during this...
1233 - sysinst should use in-fs logs now, not end-of-partition logs.

1289 Maintainer: Bill Studenmund <wrstuden (a] NetBSD.org>
1290 Scope: kernel
1291 Notes: No longer active due to lack of time, and introduction
1292 of UBC. In terms of UBC, the primary cache for
1293 file data is the VM cache, which needs to operate
1294 in terms of VM pages. As no existing device has native
1295 pages the same size as our VM pages, there already is
1296 a mapping going on between the VM system and the
1297 underlying blocks. So it would be easier and cleaner
1298 to adjust that to deal w/ different block sizes.
1299 Also with UBC, all i/o is in terms of bytes at an offset
1300 with a certain length, so the exact block size isn't a big
1301 deal.
1302
1303 Any other wrstuden-devbsize tag may (and should) go away.

1339 How to adapt a port?
1340
1341 - unify cpu_switch, cpu_exit, cpu_switchto into
1342 a single cpu_switchto. see cpu_switchto.9.
1343
1344 - implement cpu_idle. see cpu_idle.9.
1345
1346 - add a flag argument to cpu_need_resched.
1347 handle RESCHED_IMMED flag, which means "cause a preemption
1348 as soon as possible." eg. in the case of MULTIPROCESSOR,
1349 send an IPI to the target cpu.
1350
1351 - "curlwp == NULL" is not a valid check for idle state anymore.
1352 use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1353 almost always non-NULL, with exceptions like early on boot.
1354
1355 - remove idle pcbs.
1356
1357 - (if MULTIPROCESSOR) tweak processor trampoline code.
1358
1359 - (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1360 secondary processors.
1361
1362 - (if schedhz!=0) call schedclock regardless of the value of
1363 curlwp.
1364
1365 - of course, update MD users of scheduler/switching API.
