BRANCHES revision 1.305 1 # $NetBSD: BRANCHES,v 1.305 2011/02/21 02:35:55 itohy Exp $
2 #
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
27 # Start Date: date first instantiated
28 # End Date: date it was Terminated/made_Dormant, if any
29 # Base Tag: netbsd-1-5-base, etc.
30 # Maintainer: Somebody to blame.
31 # Scope: Portion of the tree covered.
32 # Notes: Various other info, perhaps explanation of special tags,

35 # There are four sections to this file:
36 # Release branches
37 # Individual developers' branches (Active/Dormant)
38 # Individual developers' branches (Terminated), and
39 # other

232 Branch: ad-audiomp
233 Description: Add MP locking to the audio drivers
234 Status: Terminated
235 Start Date: 28 February 2007
236 End Date: 7 December 2008
237 Base Tag: ad-audiomp-base
238 Maintainer: Andrew Doran <ad (a] 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
256 used for initialization, e.g. get_locks. This needs to be
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.

282 Maintainer: Ben Harris <bjh21 (a] NetBSD.org>
283 Scope: sys/arch/arm sys/arch/acorn32
284 Notes: This code was on a branch because it involves changes to

495 Scope: Kernel
496 Notes: Goals:
497
498 - Reorganize locking in UVM and serialize pmap(9) operations
499 on same page(s). New lock order: [vmpage-lock] -> pmap-lock.
500 Based on the patch from ad@.
501 - Simplify locking in pmap(9) modules by removing P->V locking.
502 - Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock)
503 to share locks among UVM objects where necessary.
504 - Optimize pmap_remove() with tracking in struct vm_map_entry.
505 - Unify /dev/mem et al in MI code and provide required locking.

511 End Date:
512 Base Tag: rpaulo-netinet-merge-pcb-base
513 Maintainer: Rui Paulo <rpaulo (a] NetBSD.org>
514 Scope: src/sys
515 Notes: No longer active due to the lack of time. If you plan to
516 continue this branch, sys/netinet/in_pcb.h already contains
517 the proposed structure layout (which was roughly discussed
518 in the tech-net mailing list).
519 I also defined INP_*() macros to mimicate FreeBSD's inpcb
520 locking style, but currently they do nothing and are not
521 yet called at the correct places (needs discussion about
522 kernel fine-grained locking).
523 To continue this branch, one needs to read all the relevant
524 inpcb/in6pcb source files and change the function names,
525 structure names, structure fields according to the new
526 layout (in6pcb is gone).
527 Don't try to build a kernel from this branch because it won't
528 work. The missing pieces required to do a complete build
529 were not committed because they were incomplete and generated
530 panics.
531 You shouldn't need to worry about KAME syncs because
532 they did most of them by now.
533 After the work is done, you are required to test the branch
534 (before the merge to -current) with an interop IPv6 test.

544 Scope: src, though all the interesting stuff is in the kernel
545 or lib/libpthread or maybe gdb.
546 Notes: This branch is based off of the netbsd-4 branch!
547 This branch is intended to stage improvements for the
548 Scheduler Activations system for NetBSD 4. Improvements
549 include not allocating memory while preparing to tsleep(),
550 reducing inappropriate upcall delivery (hopefully also
551 eliminating the need to mlock stacks), and being
552 able to pthread_kill() running threads. At this date,
553 most goals have been achieved. This branch also includes
554 fixes to gdb to support working with threaded apps.

563 Scope: src, though all the interesting stuff is in the kernel
564 Notes: This branch is intended to revive Scheduler Activations
565 in -current in the 5.0 era. This branch's main goal is
566 to re-add syscall compatability so that SA-based libpthread
567 programs can run with a -current kernel. 1:1 threading will
568 remain the NetBSD-default. This branch will re-add necessary
569 upcall support, and will also serve as a chance to clean
570 out cruft that had accumulated in the implementation over
571 time.

600 Branch: reinoud-bufcleanup
601 Description: implement and evaluate struct buf usage cleanup strategies.
602 Ideas currently in mind (preference for b):
603 a)
604 1. use of bio_ops per buffer.
605 2. allow chaining/overloading of functions in bio_ops
606 and provide some private context.
607 3. extend the bio_ops with commonly used functionality
608 like pending action counting, custom context passing,
609 last minute processing of buffer data, buffer cache
610 etc.
611 4. investigate the use of the kcont()
612 continuation-passing framework for async io
613 completion notification for bufs
614 ...
615 b)
616 1. all sequencing use of B_CALL replaced by
617 device-threads, if possible generic code around BUFQ
618 2. possibly use kcont() for async IO finished signaling
619 3. counter of pending and queued actions requestable
620 by IOCTL interface?
621 4. implement `last minute buffer fixup' calls and maybe
622 even finished I/O calls as vnode operations
623 ...

1094 probably do it wrong; instead, ask the maintainer to

1109
1110 The following processors have had cache ops
1111 written:
1112
1113 * R2000/R3000 (cache_r3k) -- light testing,
1114 needs to be beat on a lot more to make
1115 sure it's working.
1116
1117 * R4000/R4400 (cache_r4k) -- mhitch (a] NetBSD.org
1118 tracked down a bug, which has been fixed.
1119
1120 Confirmed working on R4000-with-L2.

1226 Notes: Still has a number of issues:
1227 - Some heavy workload performance issues on SMP machines.
1228 Work around this issue by turning on WAPBL_DEBUG_SERIALIZE
1229 in rev 1.1.2.11 of vfs_wapbl.c.
1230 - Removing large files (sparse only?) takes a long time.
1231 Eg, a file created with
1232 dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550
1233 takes 0:00.00 to remove on my test box without logging and
1234 0:22.25 to remove with logging. No disk IO during this...
1235 - sysinst should use in-fs logs now, not end-of-partition logs.

1321 Branch: wrstuden-devbsize
1322 Description: Modify buffer cache to deal with different devices having
1323 different block sizes. Also DEV_BSIZE would go away.

1325 Start Date: Aug or Sept 1999

1327 Base tag: wrstuden-devbsize-base
1328 Maintainer: Bill Studenmund <wrstuden (a] NetBSD.org>
1329 Scope: kernel
1330 Notes: No longer active due to lack of time, and introduction
1331 of UBC. In terms of UBC, the primary cache for
1332 file data is the VM cache, which needs to operate
1333 in terms of VM pages. As no existing device has native
1334 pages the same size as our VM pages, there already is
1335 a mapping going on between the VM system and the
1336 underlying blocks. So it would be easier and cleaner
1337 to adjust that to deal w/ different block sizes.
1338 Also with UBC, all i/o is in terms of bytes at an offset
1339 with a certain length, so the exact block size isn't a big
1340 deal.
1341
1342 Any other wrstuden-devbsize tag may (and should) go away.

1378 How to adapt a port?
1379
1380 - unify cpu_switch, cpu_exit, cpu_switchto into
1381 a single cpu_switchto. see cpu_switchto.9.
1382
1383 - implement cpu_idle. see cpu_idle.9.
1384
1385 - add a flag argument to cpu_need_resched.
1386 handle RESCHED_IMMED flag, which means "cause a preemption
1387 as soon as possible." eg. in the case of MULTIPROCESSOR,
1388 send an IPI to the target cpu.
1389
1390 - "curlwp == NULL" is not a valid check for idle state anymore.
1391 use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1392 almost always non-NULL, with exceptions like early on boot.
1393
1394 - remove idle pcbs.
1395
1396 - (if MULTIPROCESSOR) tweak processor trampoline code.
1397
1398 - (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1399 secondary processors.
1400
1401 - (if schedhz!=0) call schedclock regardless of the value of
1402 curlwp.
1403
1404 - of course, update MD users of scheduler/switching API.

1717 Maintainer: Gregory McGarry <gmcgarry (a] NetBSD.org>
1718 Scope: kernel
1719 Notes: Removing knowledge of the scheduler and its run queues
1720 from the machine-dependent context switch code is the
1721 first step in cleaning up the scheduler. It is necessary
1722 for the newlock branch, making the scheduler SMP friendly,
1723 adding real-time scheduler extensions, and reducing the
1724 number of code paths for LWP and proc switching.

1784 TODO:
1785
1786 all - Need to replace mb_*() with membar_*().
1787
1788 - Audit MUTEX_CAS() and RWLOCK_CAS() uses
1789 to see of membar_enter() is required here.
1790
1791 - Talk to ad@ -- figure out of non-atomic
1792 mutex / rwlock release is actually safe.
1793
1794 arm - Consider using a RAS technique like
1795 MIPS uses for _lock_cas() and the mutex
1796 stubs. Possibly do more than one atomic
1797 op as a RAS. Possibly implement mutex
1798 stubs using the technique.
1799
1800 m68k - Need to do 68010 support.
1801
1802 i386 - Need to change when x86_patch() is called
1803 so we can test ncpus.
1804
1805 powerpc - Figure out if we need barriers in the
1806 atomic ops themselves (hopefully not!)
1807
1808 x86_64 - Need to change when x86_patch() is called
1809 so we can test ncpus.
