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.

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.

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.

1.163 reinoud 548: Branch: reinoud-bufcleanup
1.164 reinoud 549: Description: implement and evaluate struct buf usage cleanup strategies.
550: Ideas currently in mind (preference for b):
551: a)
1.163 reinoud 552: 1. use of bio_ops per buffer.
553: 2. allow chaining/overloading of functions in bio_ops
554: and provide some private context.
1.225 wiz 555: 3. extend the bio_ops with commonly used functionality
1.163 reinoud 556: like pending action counting, custom context passing,
557: last minute processing of buffer data, buffer cache
558: etc.
559: 4. investigate the use of the kcont()
560: continuation-passing framework for async io
561: completion notification for bufs
1.164 reinoud 562: ...
563: b)
564: 1. all sequencing use of B_CALL replaced by
565: device-threads, if possible generic code around BUFQ
1.225 wiz 566: 2. possibly use kcont() for async IO finished signaling
1.164 reinoud 567: 3. counter of pending and queued actions requestable
568: by IOCTL interface?
569: 4. implement `last minute buffer fixup' calls and maybe
570: even finished I/O calls as vnode operations
571: ...

1256: to adjust that to deal w/ different block sizes.
1257: Also with UBC, all i/o is in terms of bytes at an offset

1301:
1302: - implement cpu_idle. see cpu_idle.9.
1303:
1304: - add a flag argument to cpu_need_resched.
1305: handle RESCHED_IMMED flag, which means "cause a preemption
1306: as soon as possible." eg. in the case of MULTIPROCESSOR,
1307: send an IPI to the target cpu.
1308:
1309: - "curlwp == NULL" is not a valid check for idle state anymore.
1310: use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1311: almost always non-NULL, with exceptions like early on boot.
1312:
1313: - remove idle pcbs.
1314:
1315: - (if MULTIPROCESSOR) tweak processor trampoline code.
1316:
1317: - (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1318: secondary processors.
1319:
1320: - (if schedhz!=0) call schedclock regardless of the value of
1321: curlwp.
1322:
1323: - of course, update MD users of scheduler/switching API.
