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.

323: Maintainer: Andrew Doran <ad@NetBSD.org>
324: Scope: kernel
325: Notes: Making the audio drivers MP safe is necessary before efforts
326: can be made to make the VM system MP safe. About 1/2 of the
327: drivers are converted, the remaining 1/2 need more changes.
328:
329: As of import this is snapshot of work in progress and so
330: may not compile; in particular the midi changes are very
331: much "in progress". The audio component has been tested
332: and verified to work with emuxki and auvia. There may
333: be a locking issue in the ac97 code at boot.
334:
335: The are two locks per device instance, an ISR lock and
336: a character device lock. The ISR lock replaces calls to
337: splaudio()/splx(), and will be held across calls to device
338: methods which were called at splaudio() before (e.g.
339: trigger_output). The character device lock is held across
340: calls to nearly all of the methods, excluding some only
1.225 wiz 341: used for initialization, e.g. get_locks. This needs to be
1.158 yamt 342: documented at merge time.
343:
344: To test on a multi way x86 system, search for "mpsafe" in
345: x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job
346: that will acquire the ISR lock (depends on the hardware, but
347: "while true; do mixerctl -a > /dev/null; done" may suffice).
348: Play audio, run lockstat and verify that that there is
349: contention on the ISR lock.

474: elements of the APIC that involve ACPI. In addition, better
475: abstractions are provided for the whole PIC layer. The main
476: work areas are sys/arch/x86 and sys/dev/acpi.

654: I also defined INP_*() macros to mimicate FreeBSD's inpcb
655: locking style, but currently they do nothing and are not
656: yet called at the correct places (needs discussion about
657: kernel fine-grained locking).
658: To continue this branch, one needs to read all the relevant
659: inpcb/in6pcb source files and change the function names,
1.225 wiz 660: structure names, structure fields according to the new
1.135 rpaulo 661: layout (in6pcb is gone).
662: Don't try to build a kernel from this branch because it won't
663: work. The missing pieces required to do a complete build
664: were not committed because they were incomplete and generated
665: panics.
666: You shouldn't need to worry about KAME syncs because
667: they did most of them by now.
668: After the work is done, you are required to test the branch
669: (before the merge to -current) with an interop IPv6 test.

855: last minute processing of buffer data, buffer cache
856: etc.
857: 4. investigate the use of the kcont()
858: continuation-passing framework for async io
859: completion notification for bufs
1.164 reinoud 860: ...
861: b)
862: 1. all sequencing use of B_CALL replaced by
863: device-threads, if possible generic code around BUFQ
1.225 wiz 864: 2. possibly use kcont() for async IO finished signaling
1.164 reinoud 865: 3. counter of pending and queued actions requestable
866: by IOCTL interface?
867: 4. implement `last minute buffer fixup' calls and maybe
868: even finished I/O calls as vnode operations

1641: pages the same size as our VM pages, there already is
1642: a mapping going on between the VM system and the
1643: underlying blocks. So it would be easier and cleaner
1644: to adjust that to deal w/ different block sizes.
1645: Also with UBC, all i/o is in terms of bytes at an offset
1646: with a certain length, so the exact block size isn't a big
1647: deal.

1689:
1690: - implement cpu_idle. see cpu_idle.9.
1691:
1692: - add a flag argument to cpu_need_resched.
1693: handle RESCHED_IMMED flag, which means "cause a preemption
1694: as soon as possible." eg. in the case of MULTIPROCESSOR,
1695: send an IPI to the target cpu.
1696:
1697: - "curlwp == NULL" is not a valid check for idle state anymore.
1698: use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1699: almost always non-NULL, with exceptions like early on boot.
1700:
1701: - remove idle pcbs.
1702:
1703: - (if MULTIPROCESSOR) tweak processor trampoline code.
1704:
1705: - (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1706: secondary processors.
1707:
1708: - (if schedhz!=0) call schedclock regardless of the value of
1709: curlwp.
1710:
1711: - of course, update MD users of scheduler/switching API.
