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.

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.

500 Status: Dormant
501 Start Date: Wed Feb 01 2006
502 End Date:
503 Base Tag: rpaulo-netinet-merge-pcb-base
504 Maintainer: Rui Paulo <rpaulo (a] NetBSD.org>
505 Scope: src/sys
506 Notes: No longer active due to the lack of time. If you plan to
507 continue this branch, sys/netinet/in_pcb.h already contains
508 the proposed structure layout (which was roughly discussed
509 in the tech-net mailing list).
510 I also defined INP_*() macros to mimicate FreeBSD's inpcb
511 locking style, but currently they do nothing and are not
512 yet called at the correct places (needs discussion about
513 kernel fine-grained locking).
514 To continue this branch, one needs to read all the relevant
515 inpcb/in6pcb source files and change the function names,
516 structure names, structure fields according to the new
517 layout (in6pcb is gone).
518 Don't try to build a kernel from this branch because it won't
519 work. The missing pieces required to do a complete build
520 were not committed because they were incomplete and generated
521 panics.
522 You shouldn't need to worry about KAME syncs because
523 they did most of them by now.
524 After the work is done, you are required to test the branch
525 (before the merge to -current) with an interop IPv6 test.

528 Branch: wrstuden-fixsa

532 End Date:
533 Base Tag: wrstuden-fixsa-base

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

553 Maintainer: Bill Stouder-Studenmund <wrstuden (a] NetBSD.org>
554 Scope: src, though all the interesting stuff is in the kernel
555 Notes: This branch is intended to revive Scheduler Activations
556 in -current in the 5.0 era. This branch's main goal is
557 to re-add syscall compatability so that SA-based libpthread
558 programs can run with a -current kernel. 1:1 threading will
559 remain the NetBSD-default. This branch will re-add necessary

602 are dirty.
603 - reduce the number of pmap operations by tracking page
604 dirtiness more precisely in uvm layer.

608 Branch: reinoud-bufcleanup
609 Description: implement and evaluate struct buf usage cleanup strategies.
610 Ideas currently in mind (preference for b):
611 a)
612 1. use of bio_ops per buffer.
613 2. allow chaining/overloading of functions in bio_ops
614 and provide some private context.
615 3. extend the bio_ops with commonly used functionality
616 like pending action counting, custom context passing,
617 last minute processing of buffer data, buffer cache
618 etc.
619 4. investigate the use of the kcont()
620 continuation-passing framework for async io
621 completion notification for bufs
622 ...
623 b)
624 1. all sequencing use of B_CALL replaced by
625 device-threads, if possible generic code around BUFQ
626 2. possibly use kcont() for async IO finished signaling
627 3. counter of pending and queued actions requestable
628 by IOCTL interface?
629 4. implement `last minute buffer fixup' calls and maybe
630 even finished I/O calls as vnode operations
631 ...

1099 - Simplify locking in pmap(9) modules by removing P->V locking.
1100 - Use mutex_obj(9) on vmobjlock (and thus vnode_t::v_interlock)
1101 to share locks among UVM objects where necessary.
1102 - Rewrite and optimize x86 TLB shootdown code.
1103 - Unify /dev/mem et al in MI code and provide required locking.
1104
1105 Future work:
1106
1107 - Optimize pmap_remove() with tracking in struct vm_map_entry.

1118 Code committed to the branch has booted to multiuser
1119 on at least one system.
1120
1121 Not guaranteed to compile against mainline since -current
1122 may have changed incompatibly with the last branch update;
1123 use "cvs update -D" to roll-back the rest of the tree to match.
1124
1125 Please get explicit permission from the maintainer
1126 before each commit, or your changes will be backed out.
1127 Other tags starting with sommerfeld_ are private to
1128 the developer and are guaranteed to be unstable.
1129 Only the maintainer should move tags.
1130
1131 Note that this branch uses a DIFFERENT scheme for
1132 syncing with the mainline. the maintainer uses some private
1133 scripts for keeping them in sync; if you make commits
1134 to the branch to "resynchronize" things, you'll
1135 probably do it wrong; instead, ask the maintainer to
1136 resynchronize things.

1268 - Some heavy workload performance issues on SMP machines.
1269 Work around this issue by turning on WAPBL_DEBUG_SERIALIZE
1270 in rev 1.1.2.11 of vfs_wapbl.c.
1271 - Removing large files (sparse only?) takes a long time.
1272 Eg, a file created with
1273 dd if=/dev/zero of=foox bs=1 count=1 seek=11261748520550
1274 takes 0:00.00 to remove on my test box without logging and
1275 0:22.25 to remove with logging. No disk IO during this...
1276 - sysinst should use in-fs logs now, not end-of-partition logs.

1369 Maintainer: Bill Studenmund <wrstuden (a] NetBSD.org>
1370 Scope: kernel
1371 Notes: No longer active due to lack of time, and introduction
1372 of UBC. In terms of UBC, the primary cache for
1373 file data is the VM cache, which needs to operate
1374 in terms of VM pages. As no existing device has native
1375 pages the same size as our VM pages, there already is
1376 a mapping going on between the VM system and the
1377 underlying blocks. So it would be easier and cleaner
1378 to adjust that to deal w/ different block sizes.
1379 Also with UBC, all i/o is in terms of bytes at an offset
1380 with a certain length, so the exact block size isn't a big
1381 deal.

1419 How to adapt a port?
1420
1421 - unify cpu_switch, cpu_exit, cpu_switchto into
1422 a single cpu_switchto. see cpu_switchto.9.
1423
1424 - implement cpu_idle. see cpu_idle.9.
1425
1426 - add a flag argument to cpu_need_resched.
1427 handle RESCHED_IMMED flag, which means "cause a preemption
1428 as soon as possible." eg. in the case of MULTIPROCESSOR,
1429 send an IPI to the target cpu.
1430
1431 - "curlwp == NULL" is not a valid check for idle state anymore.
1432 use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
1433 almost always non-NULL, with exceptions like early on boot.
1434
1435 - remove idle pcbs.
1436
1437 - (if MULTIPROCESSOR) tweak processor trampoline code.
1438
1439 - (if MULTIPROCESSOR) call mi_cpu_attach when attaching
1440 secondary processors.
1441
1442 - (if schedhz!=0) call schedclock regardless of the value of
1443 curlwp.
1444
1445 - of course, update MD users of scheduler/switching API.

1759 Scope: kernel
1760 Notes: Removing knowledge of the scheduler and its run queues
1761 from the machine-dependent context switch code is the
1762 first step in cleaning up the scheduler. It is necessary
1763 for the newlock branch, making the scheduler SMP friendly,
1764 adding real-time scheduler extensions, and reducing the
1765 number of code paths for LWP and proc switching.

1826
1827 all - Need to replace mb_*() with membar_*().
1828
1829 - Audit MUTEX_CAS() and RWLOCK_CAS() uses
1830 to see of membar_enter() is required here.
1831
1832 - Talk to ad@ -- figure out of non-atomic
1833 mutex / rwlock release is actually safe.
1834
1835 arm - Consider using a RAS technique like
1836 MIPS uses for _lock_cas() and the mutex
1837 stubs. Possibly do more than one atomic
1838 op as a RAS. Possibly implement mutex
1839 stubs using the technique.
1840
1841 m68k - Need to do 68010 support.
1842
1843 i386 - Need to change when x86_patch() is called
1844 so we can test ncpus.
1845
1846 powerpc - Figure out if we need barriers in the
1847 atomic ops themselves (hopefully not!)
1848
1849 x86_64 - Need to change when x86_patch() is called
1850 so we can test ncpus.
