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.

23: # Format:
24: # Branch: name of branch
25: # Description: Purpose and intention of the branch

1.158 yamt 211: Branch: ad-audiomp
212: Description: Add MP locking to the audio drivers
213: Status: Active
1.225 wiz 214: Start Date: 28 February 2007
1.158 yamt 215: End Date:
216: Base Tag: ad-audiomp-base
217: Maintainer: Andrew Doran <ad@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
1.225 wiz 235: used for initialization, e.g. get_locks. This needs to be
1.158 yamt 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.

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,
1.225 wiz 465: structure names, structure fields according to the new
1.135 rpaulo 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.

1.191 wrstuden 493: Branch: wrstuden-fixsa

497: End Date:
498: Base Tag: wrstuden-fixsa-base
499: Maintainer: Bill Stouder-Studenmund <wrstuden@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
1.253 wrstuden 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.

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.

1.163 reinoud 567: Branch: reinoud-bufcleanup
1.164 reinoud 568: Description: implement and evaluate struct buf usage cleanup strategies.
569: Ideas currently in mind (preference for b):
570: a)
1.163 reinoud 571: 1. use of bio_ops per buffer.
572: 2. allow chaining/overloading of functions in bio_ops
573: and provide some private context.
1.225 wiz 574: 3. extend the bio_ops with commonly used functionality
1.163 reinoud 575: like pending action counting, custom context passing,
576: last minute processing of buffer data, buffer cache
577: etc.
578: 4. investigate the use of the kcont()
579: continuation-passing framework for async io
580: completion notification for bufs
1.164 reinoud 581: ...
582: b)
583: 1. all sequencing use of B_CALL replaced by
584: device-threads, if possible generic code around BUFQ
1.225 wiz 585: 2. possibly use kcont() for async IO finished signaling
1.164 reinoud 586: 3. counter of pending and queued actions requestable
587: by IOCTL interface?
588: 4. implement `last minute buffer fixup' calls and maybe
589: even finished I/O calls as vnode operations
590: ...

1294: a mapping going on between the VM system and the

1296: to adjust that to deal w/ different block sizes.
1297: Also with UBC, all i/o is in terms of bytes at an offset

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