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.

435: locking style, but currently they do nothing and are not

1.225 wiz 440: structure names, structure fields according to the new
1.135 rpaulo 441: layout (in6pcb is gone).

443: work. The missing pieces required to do a complete build
444: were not committed because they were incomplete and generated
445: panics.
446: You shouldn't need to worry about KAME syncs because
447: they did most of them by now.
448: After the work is done, you are required to test the branch

527: a)

530: and provide some private context.

1.163 reinoud 532: like pending action counting, custom context passing,
533: last minute processing of buffer data, buffer cache
534: etc.
535: 4. investigate the use of the kcont()
536: continuation-passing framework for async io
537: completion notification for bufs
1.164 reinoud 538: ...
539: b)
540: 1. all sequencing use of B_CALL replaced by
541: device-threads, if possible generic code around BUFQ
1.225 wiz 542: 2. possibly use kcont() for async IO finished signaling
1.164 reinoud 543: 3. counter of pending and queued actions requestable
544: by IOCTL interface?
545: 4. implement `last minute buffer fixup' calls and maybe
546: even finished I/O calls as vnode operations

1216: pages the same size as our VM pages, there already is
1217: a mapping going on between the VM system and the
1218: underlying blocks. So it would be easier and cleaner
1219: to adjust that to deal w/ different block sizes.
1220: Also with UBC, all i/o is in terms of bytes at an offset
1221: with a certain length, so the exact block size isn't a big

1264:
1265: - implement cpu_idle. see cpu_idle.9.
1266:
1267: - add a flag argument to cpu_need_resched.
1268: handle RESCHED_IMMED flag, which means "cause a preemption
1269: as soon as possible." eg. in the case of MULTIPROCESSOR,
1270: send an IPI to the target cpu.
1271:
1272: - "curlwp == NULL" is not a valid check for idle state anymore.
1273: use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1274: almost always non-NULL, with exceptions like early on boot.
1275:
1276: - remove idle pcbs.
1277:
1278: - (if MULTIPROCESSOR) tweak processor trampoline code.
1279:
1280: - (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1281: secondary processors.
1282:
1283: - (if schedhz!=0) call schedclock regardless of the value of
1284: curlwp.
1285:
1286: - of course, update MD users of scheduler/switching API.
