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 259: Base Tag: ad-audiomp-base
260: Maintainer: Andrew Doran <ad@NetBSD.org>
261: Scope: kernel
262: Notes: Making the audio drivers MP safe is necessary before efforts
263: can be made to make the VM system MP safe. About 1/2 of the
264: drivers are converted, the remaining 1/2 need more changes.
265:
266: As of import this is snapshot of work in progress and so
267: may not compile; in particular the midi changes are very
268: much "in progress". The audio component has been tested
269: and verified to work with emuxki and auvia. There may
270: be a locking issue in the ac97 code at boot.
271:
272: The are two locks per device instance, an ISR lock and
273: a character device lock. The ISR lock replaces calls to
274: splaudio()/splx(), and will be held across calls to device
275: methods which were called at splaudio() before (e.g.
276: trigger_output). The character device lock is held across
277: calls to nearly all of the methods, excluding some only
1.225 wiz 278: used for initialization, e.g. get_locks. This needs to be
1.158 yamt 279: documented at merge time.
280:
281: To test on a multi way x86 system, search for "mpsafe" in
282: x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job
283: that will acquire the ISR lock (depends on the hardware, but
284: "while true; do mixerctl -a > /dev/null; done" may suffice).
285: Play audio, run lockstat and verify that that there is
286: contention on the ISR lock.

577: continue this branch, sys/netinet/in_pcb.h already contains
578: the proposed structure layout (which was roughly discussed
579: in the tech-net mailing list).
580: I also defined INP_*() macros to mimicate FreeBSD's inpcb
581: locking style, but currently they do nothing and are not
582: yet called at the correct places (needs discussion about
583: kernel fine-grained locking).
584: To continue this branch, one needs to read all the relevant
585: inpcb/in6pcb source files and change the function names,
1.225 wiz 586: structure names, structure fields according to the new
1.135 rpaulo 587: layout (in6pcb is gone).
588: Don't try to build a kernel from this branch because it won't
589: work. The missing pieces required to do a complete build
590: were not committed because they were incomplete and generated
591: panics.
592: You shouldn't need to worry about KAME syncs because
593: they did most of them by now.
594: After the work is done, you are required to test the branch
595: (before the merge to -current) with an interop IPv6 test.

628: programs can run with a -current kernel. 1:1 threading will
629: remain the NetBSD-default. This branch will re-add necessary
630: upcall support, and will also serve as a chance to clean

778: and provide some private context.
1.225 wiz 779: 3. extend the bio_ops with commonly used functionality
1.163 reinoud 780: like pending action counting, custom context passing,
781: last minute processing of buffer data, buffer cache
782: etc.
783: 4. investigate the use of the kcont()
784: continuation-passing framework for async io
785: completion notification for bufs
1.164 reinoud 786: ...
787: b)
788: 1. all sequencing use of B_CALL replaced by
789: device-threads, if possible generic code around BUFQ
1.225 wiz 790: 2. possibly use kcont() for async IO finished signaling
1.164 reinoud 791: 3. counter of pending and queued actions requestable
792: by IOCTL interface?
793: 4. implement `last minute buffer fixup' calls and maybe
794: even finished I/O calls as vnode operations

1432: - Some heavy workload performance issues on SMP machines.
1433: Work around this issue by turning on WAPBL_DEBUG_SERIALIZE
1434: in rev 1.1.2.11 of vfs_wapbl.c.
1435: - Removing large files (sparse only?) takes a long time.
1436: Eg, a file created with
1437: dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550
1438: takes 0:00.00 to remove on my test box without logging and
1439: 0:22.25 to remove with logging. No disk IO during this...
1440: - sysinst should use in-fs logs now, not end-of-partition logs.

1535: Notes: No longer active due to lack of time, and introduction
1536: of UBC. In terms of UBC, the primary cache for
1537: file data is the VM cache, which needs to operate
1538: in terms of VM pages. As no existing device has native
1539: pages the same size as our VM pages, there already is
1540: a mapping going on between the VM system and the
1541: underlying blocks. So it would be easier and cleaner
1542: to adjust that to deal w/ different block sizes.
1543: Also with UBC, all i/o is in terms of bytes at an offset
1544: with a certain length, so the exact block size isn't a big
1545: deal.

1583: How to adapt a port?
1584:
1585: - unify cpu_switch, cpu_exit, cpu_switchto into
1586: a single cpu_switchto. see cpu_switchto.9.
1587:
1588: - implement cpu_idle. see cpu_idle.9.
1589:
1590: - add a flag argument to cpu_need_resched.
1591: handle RESCHED_IMMED flag, which means "cause a preemption
1592: as soon as possible." eg. in the case of MULTIPROCESSOR,
1593: send an IPI to the target cpu.
1594:
1595: - "curlwp == NULL" is not a valid check for idle state anymore.
1596: use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1597: almost always non-NULL, with exceptions like early on boot.
1598:
1599: - remove idle pcbs.
1600:
1601: - (if MULTIPROCESSOR) tweak processor trampoline code.
1602:
1603: - (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1604: secondary processors.
1605:
1606: - (if schedhz!=0) call schedclock regardless of the value of
1607: curlwp.
1608:
1609: - of course, update MD users of scheduler/switching API.

1990:
1991: all - Need to replace mb_*() with membar_*().
1992:
1993: - Audit MUTEX_CAS() and RWLOCK_CAS() uses
1994: to see of membar_enter() is required here.
1995:
1996: - Talk to ad@ -- figure out of non-atomic
1997: mutex / rwlock release is actually safe.
1998:
1999: arm - Consider using a RAS technique like
2000: MIPS uses for _lock_cas() and the mutex
2001: stubs. Possibly do more than one atomic
2002: op as a RAS. Possibly implement mutex
2003: stubs using the technique.
2004:
2005: m68k - Need to do 68010 support.
2006:
2007: i386 - Need to change when x86_patch() is called
2008: so we can test ncpus.
2009:
2010: powerpc - Figure out if we need barriers in the
2011: atomic ops themselves (hopefully not!)
2012:
2013: x86_64 - Need to change when x86_patch() is called
2014: so we can test ncpus.
