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 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.
243:
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.
249:
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
1.225 wiz 256: used for initialization, e.g. get_locks. This needs to be
1.158 yamt 257: documented at merge time.
258:
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.

507: continue this branch, sys/netinet/in_pcb.h already contains
508: the proposed structure layout (which was roughly discussed
509: in the tech-net mailing list).
510: I also defined INP_*() macros to mimicate FreeBSD's inpcb
511: locking style, but currently they do nothing and are not
512: yet called at the correct places (needs discussion about
513: kernel fine-grained locking).
514: To continue this branch, one needs to read all the relevant
515: inpcb/in6pcb source files and change the function names,
1.225 wiz 516: structure names, structure fields according to the new
1.135 rpaulo 517: layout (in6pcb is gone).
518: Don't try to build a kernel from this branch because it won't
519: work. The missing pieces required to do a complete build
520: were not committed because they were incomplete and generated
521: panics.
522: You shouldn't need to worry about KAME syncs because
523: they did most of them by now.
524: After the work is done, you are required to test the branch
525: (before the merge to -current) with an interop IPv6 test.

540: include not allocating memory while preparing to tsleep(),
541: reducing inappropriate upcall delivery (hopefully also

597: and provide some private context.
1.225 wiz 598: 3. extend the bio_ops with commonly used functionality
1.163 reinoud 599: like pending action counting, custom context passing,
600: last minute processing of buffer data, buffer cache
601: etc.
602: 4. investigate the use of the kcont()
603: continuation-passing framework for async io
604: completion notification for bufs
1.164 reinoud 605: ...
606: b)
607: 1. all sequencing use of B_CALL replaced by
608: device-threads, if possible generic code around BUFQ
1.225 wiz 609: 2. possibly use kcont() for async IO finished signaling
1.164 reinoud 610: 3. counter of pending and queued actions requestable
611: by IOCTL interface?
612: 4. implement `last minute buffer fixup' calls and maybe
613: even finished I/O calls as vnode operations

1404: - "curlwp == NULL" is not a valid check for idle state anymore.
1405: use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1406: almost always non-NULL, with exceptions like early on boot.
1407:
1408: - remove idle pcbs.
1409:
1410: - (if MULTIPROCESSOR) tweak processor trampoline code.
1411:
1412: - (if MULTIPROCESSOR) call mi_cpu_attach when attaching

1414:
