1 # $NetBSD: BRANCHES,v 1.284 2009/08/10 21:27:46 matt 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.

232 Branch: ad-audiomp
233 Description: Add MP locking to the audio drivers
234 Status: Terminated
235 Start Date: 28 February 2007
236 End Date: 7 December 2008
237 Base Tag: ad-audiomp-base
238 Maintainer: Andrew Doran <ad@NetBSD.org>
239 Scope: kernel
240 Notes: Making the audio drivers MP safe is necessary before efforts
241 can be made to make the VM system MP safe. About 1/2 of the
242 drivers are converted, the remaining 1/2 need more changes.
244 As of import this is snapshot of work in progress and so
245 may not compile; in particular the midi changes are very
246 much "in progress". The audio component has been tested
247 and verified to work with emuxki and auvia. There may
248 be a locking issue in the ac97 code at boot.
250 The are two locks per device instance, an ISR lock and
251 a character device lock. The ISR lock replaces calls to
252 splaudio()/splx(), and will be held across calls to device
253 methods which were called at splaudio() before (e.g.
254 trigger_output). The character device lock is held across
255 calls to nearly all of the methods, excluding some only
256 used for initialization, e.g. get_locks. This needs to be
257 documented at merge time.
259 To test on a multi way x86 system, search for "mpsafe" in
260 x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job
261 that will acquire the ISR lock (depends on the hardware, but
262 "while true; do mixerctl -a > /dev/null; done" may suffice).
263 Play audio, run lockstat and verify that that there is
264 contention on the ISR lock.
266 Branch: ad-audiomp2
267 Description: Add MP locking to the audio drivers
268 Status: Active
269 Start Date: 7 December 2008
270 End Date:
271 Base Tag: ad-audiomp2-base

281 Base Tag: bjh21-hydra-base
282 Maintainer: Ben Harris <bjh21@NetBSD.org>
283 Scope: sys/arch/arm sys/arch/acorn32
284 Notes: This code was on a branch because it involves changes to
285 cpuswitch.S which would otherwise make merging the
286 nathanw_sa branch difficult.
288 Branch: chris-arm-intr-rework
289 Description: Rework arm interrupt handling code
290 Status: Active
291 Start Date: 11 Aug 2007

294 Maintainer: Chris Gilbert <chris@NetBSD.org>
295 Scope: sys/arch/arm sys/arch/cats (other arm archs to follow)
296 Notes: Rework arm interrupt code to provide a shared set of interrupt
297 routines, and allow improvements to be shared across all arm
298 based hardware.
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@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.
315 Branch: gmcgarry_ucred

357 Notes: This branch contains the code required to support the Xen
358 save/restore/migrate facilities. It affects domU frontend
359 drivers (xbd, xennet, xencons, hypervisor), autoconf(9)
360 machinery, as well as MD code (mostly pmap(9)).

493 Start Date: Wed Feb 01 2006
494 End Date:
495 Base Tag: rpaulo-netinet-merge-pcb-base
496 Maintainer: Rui Paulo <rpaulo@NetBSD.org>
497 Scope: src/sys
498 Notes: No longer active due to the lack of time. If you plan to
499 continue this branch, sys/netinet/in_pcb.h already contains
500 the proposed structure layout (which was roughly discussed
501 in the tech-net mailing list).
502 I also defined INP_*() macros to mimicate FreeBSD's inpcb
503 locking style, but currently they do nothing and are not
504 yet called at the correct places (needs discussion about
505 kernel fine-grained locking).
506 To continue this branch, one needs to read all the relevant
507 inpcb/in6pcb source files and change the function names,
508 structure names, structure fields according to the new
509 layout (in6pcb is gone).
510 Don't try to build a kernel from this branch because it won't
511 work. The missing pieces required to do a complete build
512 were not committed because they were incomplete and generated
513 panics.
514 You shouldn't need to worry about KAME syncs because
515 they did most of them by now.
516 After the work is done, you are required to test the branch
517 (before the merge to -current) with an interop IPv6 test.

536 Branch: wrstuden-fixsa

540 End Date:
541 Base Tag: wrstuden-fixsa-base
542 Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org>
543 Scope: src, though all the interesting stuff is in the kernel
544 or lib/libpthread or maybe gdb.
545 Notes: This branch is based off of the netbsd-4 branch!
546 This branch is intended to stage improvements for the
547 Scheduler Activations system for NetBSD 4. Improvements
548 include not allocating memory while preparing to tsleep(),
549 reducing inappropriate upcall delivery (hopefully also
550 eliminating the need to mlock stacks), and being
551 able to pthread_kill() running threads. At this date,
552 most goals have been achieved. This branch also includes
553 fixes to gdb to support working with threaded apps.

562 Scope: src, though all the interesting stuff is in the kernel
563 Notes: This branch is intended to revive Scheduler Activations
564 in -current in the 5.0 era. This branch's main goal is
565 to re-add syscall compatability so that SA-based libpthread
566 programs can run with a -current kernel. 1:1 threading will
567 remain the NetBSD-default. This branch will re-add necessary
568 upcall support, and will also serve as a chance to clean
569 out cruft that had accumulated in the implementation over
570 time.

584 - investigate if PMAP_PREFER equivalent can be done
585 with vmem_xalloc. find a tester with hardware for it.
586 - g/c replaced code, including kmapent and malloc.
587 - consider to remove other submaps. eg. mb_map

599 Branch: reinoud-bufcleanup
600 Description: implement and evaluate struct buf usage cleanup strategies.
601 Ideas currently in mind (preference for b):
602 a)
603 1. use of bio_ops per buffer.
604 2. allow chaining/overloading of functions in bio_ops
605 and provide some private context.
606 3. extend the bio_ops with commonly used functionality
607 like pending action counting, custom context passing,
608 last minute processing of buffer data, buffer cache
609 etc.
610 4. investigate the use of the kcont()
611 continuation-passing framework for async io
612 completion notification for bufs
613 ...
614 b)
615 1. all sequencing use of B_CALL replaced by
616 device-threads, if possible generic code around BUFQ
617 2. possibly use kcont() for async IO finished signaling
618 3. counter of pending and queued actions requestable
619 by IOCTL interface?
620 4. implement `last minute buffer fixup' calls and maybe
621 even finished I/O calls as vnode operations
622 ...

686 - Talk to ad@ -- figure out of non-atomic
687 mutex / rwlock release is actually safe.
689 arm - Consider using a RAS technique like
690 MIPS uses for _lock_cas() and the mutex
691 stubs. Possibly do more than one atomic
692 op as a RAS. Possibly implement mutex
693 stubs using the technique.
695 m68k - Need to do 68010 support.

1139 Notes:
1140 Code committed to the branch has booted to multiuser
1141 on at least one system.
1143 Not guaranteed to compile against mainline since -current
1144 may have changed incompatibly with the last branch update;
1145 use "cvs update -D" to roll-back the rest of the tree to match.
1147 Please get explicit permission from the maintainer
1148 before each commit, or your changes will be backed out.
1149 Other tags starting with sommerfeld_ are private to
1150 the developer and are guaranteed to be unstable.
1151 Only the maintainer should move tags.
1153 Note that this branch uses a DIFFERENT scheme for
1154 syncing with the mainline. the maintainer uses some private
1155 scripts for keeping them in sync; if you make commits
1156 to the branch to "resynchronize" things, you'll
1157 probably do it wrong; instead, ask the maintainer to
1158 resynchronize things.

1163 Branch: thorpej-mips-cache
1164 Description: overhaul MIPS cache support code
1165 Status: Terminated; merged to -current
1166 Start Date: Oct 23 2001
1167 End Date: Nov 14 2001
1168 Base Tag: thorpej-mips-cache-base
1169 Scope: syssrc
1170 Notes: This branch needs more debugging, testing, and more
1171 ports need to be converted to the new world order.
1173 The following processors have had cache ops
1174 written:
1176 * R2000/R3000 (cache_r3k) -- light testing,
1177 needs to be beat on a lot more to make
1178 sure it's working.
1180 * R4000/R4400 (cache_r4k) -- mhitch@NetBSD.org
1181 tracked down a bug, which has been fixed.
1183 Confirmed working on R4000-with-L2.
1185 Confirmed working on R4400-no-L2 and
1186 R4400-with-L2.
1188 * R4600/R5000 (cache_r5k) -- shin@NetBSD.org
1189 has committed fixes to this code.
1191 Confirmed working on R4600 v2 (SGI IP-22 with
1192 no SysAD L2 cache).
1194 Confirmed working on RM5260 (Algorithmics P-5064).
1196 * TX39 (cache_tx39) -- uch@NetBSD.org has
1197 committed fixes to this code. Awaiting
1198 confirmation that it is working properly.
1200 * R5900 (cache_r5900) -- uch@NetBSD.org has
1201 written this code and tested it on a
1202 PlayStation 2.
1204 The following ports have been updated to compile (and
1205 use optimized-for-processor bus_dma routines). Those
1206 that have been tested and work are marked with [WORKING].
1208 * algor [WORKING]
1210 * arc [WORKING]
1212 * pmax [WORKING]
1214 * playstation2 [WORKING]
1215 Needs optimized bus_dmamap_sync().
1217 * hpcmips [need verification that this is working]
1218 Needs optimized bus_dmamap_sync().
1220 * sgimips [WORKING]
1221 Needs optimized bus_dmamap_sync().
1223 * cobalt [need testing]
1225 * mipsco [need testing]
1227 * newsmips [need testing]

1289 Notes: Still has a number of issues:
1290 - Some heavy workload performance issues on SMP machines.
1291 Work around this issue by turning on WAPBL_DEBUG_SERIALIZE
1292 in rev 1.1.2.11 of vfs_wapbl.c.
1293 - Removing large files (sparse only?) takes a long time.
1294 Eg, a file created with
1295 dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550
1296 takes 0:00.00 to remove on my test box without logging and
1297 0:22.25 to remove with logging. No disk IO during this...
1298 - sysinst should use in-fs logs now, not end-of-partition logs.

1347 Branch: wrstuden-devbsize
1348 Description: Modify buffer cache to deal with different devices having
1349 different block sizes. Also DEV_BSIZE would go away.
1350 Status: Terminated
1351 Start Date: Aug or Sept 1999
1352 End Date: 1 Apr 2000
1353 Base tag: wrstuden-devbsize-base
1354 Maintainer: Bill Studenmund <wrstuden@NetBSD.org>
1355 Scope: kernel
1356 Notes: No longer active due to lack of time, and introduction
1357 of UBC. In terms of UBC, the primary cache for
1358 file data is the VM cache, which needs to operate
1359 in terms of VM pages. As no existing device has native
1360 pages the same size as our VM pages, there already is
1361 a mapping going on between the VM system and the
1362 underlying blocks. So it would be easier and cleaner
1363 to adjust that to deal w/ different block sizes.
1364 Also with UBC, all i/o is in terms of bytes at an offset
1365 with a certain length, so the exact block size isn't a big
1366 deal.
1368 Any other wrstuden-devbsize tag may (and should) go away.

1404 How to adapt a port?
1406 - unify cpu_switch, cpu_exit, cpu_switchto into
1407 a single cpu_switchto. see cpu_switchto.9.
1409 - implement cpu_idle. see cpu_idle.9.
1411 - add a flag argument to cpu_need_resched.
1412 handle RESCHED_IMMED flag, which means "cause a preemption
1413 as soon as possible." eg. in the case of MULTIPROCESSOR,
1414 send an IPI to the target cpu.
1416 - "curlwp == NULL" is not a valid check for idle state anymore.
1417 use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1418 almost always non-NULL, with exceptions like early on boot.
1420 - remove idle pcbs.
1422 - (if MULTIPROCESSOR) tweak processor trampoline code.
1424 - (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1425 secondary processors.
1427 - (if schedhz!=0) call schedclock regardless of the value of
1428 curlwp.
1430 - of course, update MD users of scheduler/switching API.
