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.
22: #
23: # Format:
24: # Branch: name of branch
25: # Description: Purpose and intention of the branch
26: # Status: Active/Terminated/Dormant

335: Maintainer: Andrew Doran <ad@NetBSD.org>
336: Scope: kernel
337: Notes: Making the audio drivers MP safe is necessary before efforts
338: can be made to make the VM system MP safe. About 1/2 of the
339: drivers are converted, the remaining 1/2 need more changes.
340:
341: As of import this is snapshot of work in progress and so
342: may not compile; in particular the midi changes are very
343: much "in progress". The audio component has been tested
344: and verified to work with emuxki and auvia. There may
345: be a locking issue in the ac97 code at boot.
346:
347: The are two locks per device instance, an ISR lock and
348: a character device lock. The ISR lock replaces calls to
349: splaudio()/splx(), and will be held across calls to device
350: methods which were called at splaudio() before (e.g.
351: trigger_output). The character device lock is held across
352: calls to nearly all of the methods, excluding some only
1.225 wiz 353: used for initialization, e.g. get_locks. This needs to be
1.158 yamt 354: documented at merge time.
355:
356: To test on a multi way x86 system, search for "mpsafe" in
357: x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job
358: that will acquire the ISR lock (depends on the hardware, but
359: "while true; do mixerctl -a > /dev/null; done" may suffice).
360: Play audio, run lockstat and verify that that there is
361: contention on the ISR lock.

676: I also defined INP_*() macros to mimicate FreeBSD's inpcb
677: locking style, but currently they do nothing and are not
678: yet called at the correct places (needs discussion about
679: kernel fine-grained locking).
680: To continue this branch, one needs to read all the relevant
681: inpcb/in6pcb source files and change the function names,
1.225 wiz 682: structure names, structure fields according to the new
1.135 rpaulo 683: layout (in6pcb is gone).
684: Don't try to build a kernel from this branch because it won't
685: work. The missing pieces required to do a complete build
686: were not committed because they were incomplete and generated
687: panics.
688: You shouldn't need to worry about KAME syncs because
689: they did most of them by now.
690: After the work is done, you are required to test the branch
691: (before the merge to -current) with an interop IPv6 test.

1.163 reinoud 876: like pending action counting, custom context passing,
877: last minute processing of buffer data, buffer cache
878: etc.
879: 4. investigate the use of the kcont()
880: continuation-passing framework for async io
881: completion notification for bufs
1.164 reinoud 882: ...
883: b)
884: 1. all sequencing use of B_CALL replaced by
885: device-threads, if possible generic code around BUFQ
1.225 wiz 886: 2. possibly use kcont() for async IO finished signaling
1.164 reinoud 887: 3. counter of pending and queued actions requestable
888: by IOCTL interface?
889: 4. implement `last minute buffer fixup' calls and maybe
890: even finished I/O calls as vnode operations

1391:
1392: - Reorganize locking in UVM and serialize pmap(9) operations
1393: on same page(s). New lock order: [vmpage-lock] -> pmap-lock.
1394: Based on the patch from ad@.
1395: - Simplify locking in pmap(9) modules by removing P->V locking.
1396: - Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock)
1397: to share locks among UVM objects where necessary.
1398: - Rewrite and optimize x86 TLB shootdown code.
1399: - Unify /dev/mem et al in MI code and provide required locking.
1400:
1401: Future work:
1402:
1403: - Optimize pmap_remove() with tracking in struct vm_map_entry.

1672: a mapping going on between the VM system and the

1674: to adjust that to deal w/ different block sizes.
1675: Also with UBC, all i/o is in terms of bytes at an offset

1719:
1720: - implement cpu_idle. see cpu_idle.9.
1721:
1722: - add a flag argument to cpu_need_resched.
1723: handle RESCHED_IMMED flag, which means "cause a preemption
1724: as soon as possible." eg. in the case of MULTIPROCESSOR,
1725: send an IPI to the target cpu.
1726:
1727: - "curlwp == NULL" is not a valid check for idle state anymore.
1728: use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1729: almost always non-NULL, with exceptions like early on boot.
1730:
1731: - remove idle pcbs.
1732:
1733: - (if MULTIPROCESSOR) tweak processor trampoline code.
1734:
1735: - (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1736: secondary processors.
1737:
1738: - (if schedhz!=0) call schedclock regardless of the value of
1739: curlwp.
1740:
1741: - of course, update MD users of scheduler/switching API.
