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 248: Base Tag: ad-audiomp-base
249: Maintainer: Andrew Doran <ad@NetBSD.org>
250: Scope: kernel
251: Notes: Making the audio drivers MP safe is necessary before efforts
252: can be made to make the VM system MP safe. About 1/2 of the
253: drivers are converted, the remaining 1/2 need more changes.
254:
255: As of import this is snapshot of work in progress and so
256: may not compile; in particular the midi changes are very
257: much "in progress". The audio component has been tested
258: and verified to work with emuxki and auvia. There may
259: be a locking issue in the ac97 code at boot.
260:
261: The are two locks per device instance, an ISR lock and
262: a character device lock. The ISR lock replaces calls to
263: splaudio()/splx(), and will be held across calls to device
264: methods which were called at splaudio() before (e.g.
265: trigger_output). The character device lock is held across
266: calls to nearly all of the methods, excluding some only
1.225 wiz 267: used for initialization, e.g. get_locks. This needs to be
1.158 yamt 268: documented at merge time.
269:
270: To test on a multi way x86 system, search for "mpsafe" in
271: x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job
272: that will acquire the ISR lock (depends on the hardware, but
273: "while true; do mixerctl -a > /dev/null; done" may suffice).
274: Play audio, run lockstat and verify that that there is
275: contention on the ISR lock.

566: continue this branch, sys/netinet/in_pcb.h already contains
567: the proposed structure layout (which was roughly discussed
568: in the tech-net mailing list).
569: I also defined INP_*() macros to mimicate FreeBSD's inpcb
570: locking style, but currently they do nothing and are not
571: yet called at the correct places (needs discussion about
572: kernel fine-grained locking).
573: To continue this branch, one needs to read all the relevant
574: inpcb/in6pcb source files and change the function names,
1.225 wiz 575: structure names, structure fields according to the new
1.135 rpaulo 576: layout (in6pcb is gone).
577: Don't try to build a kernel from this branch because it won't
578: work. The missing pieces required to do a complete build
579: were not committed because they were incomplete and generated
580: panics.
581: You shouldn't need to worry about KAME syncs because
582: they did most of them by now.
583: After the work is done, you are required to test the branch
584: (before the merge to -current) with an interop IPv6 test.

617: programs can run with a -current kernel. 1:1 threading will
618: remain the NetBSD-default. This branch will re-add necessary
619: upcall support, and will also serve as a chance to clean
620: out cruft that had accumulated in the implementation over

764: a)

766: 2. allow chaining/overloading of functions in bio_ops
767: and provide some private context.
1.225 wiz 768: 3. extend the bio_ops with commonly used functionality
1.163 reinoud 769: like pending action counting, custom context passing,
770: last minute processing of buffer data, buffer cache
771: etc.
772: 4. investigate the use of the kcont()
773: continuation-passing framework for async io
774: completion notification for bufs
1.164 reinoud 775: ...
776: b)
777: 1. all sequencing use of B_CALL replaced by
778: device-threads, if possible generic code around BUFQ
1.225 wiz 779: 2. possibly use kcont() for async IO finished signaling
1.164 reinoud 780: 3. counter of pending and queued actions requestable
781: by IOCTL interface?
782: 4. implement `last minute buffer fixup' calls and maybe
783: even finished I/O calls as vnode operations

1420: Notes: Still has a number of issues:
1421: - Some heavy workload performance issues on SMP machines.
1422: Work around this issue by turning on WAPBL_DEBUG_SERIALIZE
1423: in rev 1.1.2.11 of vfs_wapbl.c.
1424: - Removing large files (sparse only?) takes a long time.
1425: Eg, a file created with
1426: dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550
1427: takes 0:00.00 to remove on my test box without logging and
1428: 0:22.25 to remove with logging. No disk IO during this...
1429: - sysinst should use in-fs logs now, not end-of-partition logs.

1524: Notes: No longer active due to lack of time, and introduction
1525: of UBC. In terms of UBC, the primary cache for
1526: file data is the VM cache, which needs to operate
1527: in terms of VM pages. As no existing device has native
1528: pages the same size as our VM pages, there already is
1529: a mapping going on between the VM system and the
1530: underlying blocks. So it would be easier and cleaner
1531: to adjust that to deal w/ different block sizes.
1532: Also with UBC, all i/o is in terms of bytes at an offset
1533: with a certain length, so the exact block size isn't a big
1534: deal.

1536: Any other wrstuden-devbsize tag may (and should) go away.

1572: How to adapt a port?
1573:
1574: - unify cpu_switch, cpu_exit, cpu_switchto into
1575: a single cpu_switchto. see cpu_switchto.9.
1576:
1577: - implement cpu_idle. see cpu_idle.9.
1578:
1579: - add a flag argument to cpu_need_resched.
1580: handle RESCHED_IMMED flag, which means "cause a preemption
1581: as soon as possible." eg. in the case of MULTIPROCESSOR,
1582: send an IPI to the target cpu.
1583:
1584: - "curlwp == NULL" is not a valid check for idle state anymore.
1585: use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1586: almost always non-NULL, with exceptions like early on boot.
1587:
1588: - remove idle pcbs.
1589:
1590: - (if MULTIPROCESSOR) tweak processor trampoline code.
1591:
1592: - (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1593: secondary processors.
1594:
1595: - (if schedhz!=0) call schedclock regardless of the value of
1596: curlwp.
1597:
1598: - of course, update MD users of scheduler/switching API.

1979:
1980: all - Need to replace mb_*() with membar_*().
1981:
1982: - Audit MUTEX_CAS() and RWLOCK_CAS() uses
1983: to see of membar_enter() is required here.
1984:
1985: - Talk to ad@ -- figure out of non-atomic
1986: mutex / rwlock release is actually safe.
1987:
1988: arm - Consider using a RAS technique like
1989: MIPS uses for _lock_cas() and the mutex
1990: stubs. Possibly do more than one atomic
1991: op as a RAS. Possibly implement mutex
1992: stubs using the technique.
1993:
1994: m68k - Need to do 68010 support.
1995:
1996: i386 - Need to change when x86_patch() is called
1997: so we can test ncpus.
1998:
1999: powerpc - Figure out if we need barriers in the
2000: atomic ops themselves (hopefully not!)
2001:
2002: x86_64 - Need to change when x86_patch() is called
2003: so we can test ncpus.
