# $NetBSD: BRANCHES,v 1.350 2019/05/25 02:49:26 isaki Exp $
#
# This file contains a list of branches that exist in the NetBSD CVS
# tree and their current state.
#
# This list is necessarily incomplete.
#
# Within reason, developers may create branch and version tags at any
# time for any purpose. To avoid name collisions, private tags should
# have names which begin with the developer's NetBSD login name
# followed by a - or _ character (e.g., thorpej_scsipi,
# thorpej-signal)
#
# Any branch or version tag not listed here should be assumed to be
# private to the developer who created it. It is inappropriate for
# anyone other than that developer to commit, move tags, or otherwise
# modify the contents of the branch.
#
# Please update this file when a new branch is ready for consumption
# by folks other than the maintainer, or when the use or status of an
# existing branch changes significantly.
#
# Format:
# Branch: name of branch
# Description: Purpose and intention of the branch
# Status: Active/Terminated/Dormant
# Start Date: date first instantiated
# End Date: date it was Terminated/made_Dormant, if any
# Base Tag: netbsd-1-5-base, etc.
# Maintainer: Somebody to blame.
# Scope: Portion of the tree covered.
# Notes: Various other info, perhaps explanation of special tags,
# who-may-commit policies, etc.
#
# There are four sections to this file:
# Release branches
# Individual developers' branches (Active/Dormant)
# Individual developers' branches (Terminated), and
# other
#
# Entries within each section should be alphabetized.

Branch: ad-audiomp
Description: Add MP locking to the audio drivers
Status: Terminated
Start Date: 28 February 2007
End Date: 7 December 2008
Base Tag: ad-audiomp-base
Maintainer: Andrew Doran <ad@NetBSD.org>
Scope: kernel
Notes: Making the audio drivers MP safe is necessary before efforts
can be made to make the VM system MP safe. About 1/2 of the
drivers are converted, the remaining 1/2 need more changes.
As of import this is snapshot of work in progress and so
may not compile; in particular the midi changes are very
much "in progress". The audio component has been tested
and verified to work with emuxki and auvia. There may
be a locking issue in the ac97 code at boot.
The are two locks per device instance, an ISR lock and
a character device lock. The ISR lock replaces calls to
splaudio()/splx(), and will be held across calls to device
methods which were called at splaudio() before (e.g.
trigger_output). The character device lock is held across
calls to nearly all of the methods, excluding some only
used for initialization, e.g. get_locks. This needs to be
documented at merge time.
To test on a multi way x86 system, search for "mpsafe" in
x86/x86/intr.c and change IPL_SCHED to IPL_AUDIO. Run a job
that will acquire the ISR lock (depends on the hardware, but
"while true; do mixerctl -a > /dev/null; done" may suffice).
Play audio, run lockstat and verify that that there is
contention on the ISR lock.

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

Branch: wrstuden-fixsa
Description: Fix a number of issues present with Scheduler Activations.
Status: Active
Start Date: 15 May 2007
End Date:
Base Tag: wrstuden-fixsa-base
Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org>
Scope: src, though all the interesting stuff is in the kernel
or lib/libpthread or maybe gdb.
Notes: This branch is based off of the netbsd-4 branch!
This branch is intended to stage improvements for the
Scheduler Activations system for NetBSD 4. Improvements
include not allocating memory while preparing to tsleep(),
reducing inappropriate upcall delivery (hopefully also
eliminating the need to mlock stacks), and being
able to pthread_kill() running threads. At this date,
most goals have been achieved. This branch also includes
fixes to gdb to support working with threaded apps.
Branch: wrstuden-revivesa
Description: Fix a number of issues present with Scheduler Activations.
Status: Active

End Date:
Base Tag: wrstuden-revivesa-base
Maintainer: Bill Stouder-Studenmund <wrstuden@NetBSD.org>
Scope: src, though all the interesting stuff is in the kernel
Notes: This branch is intended to revive Scheduler Activations
in -current in the 5.0 era. This branch's main goal is
to re-add syscall compatability so that SA-based libpthread
programs can run with a -current kernel. 1:1 threading will
remain the NetBSD-default. This branch will re-add necessary
upcall support, and will also serve as a chance to clean
out cruft that had accumulated in the implementation over
time.

Notes: - maintain object pages in radix tree rather than rb tree.
- shrink the size of vm_page.
- reduce unnecessary page scan in putpages. esp. when an
object has a ton of pages cached but only a few of them
are dirty.
- reduce the number of pmap operations by tracking page
dirtiness more precisely in uvm layer.
- fix nfs commit range tracking.
- fix nfs write clustering. XXX hack
- fix A->O loaning
- write radixtree(9) man page
TODO:
- benchmark
- test
- make the write clustering fix less kludgy
- fix or disable the ad-hoc per-cpu statistic
- disable A->O loan as its benefit is unclear at best

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

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

Scope: sys/arch/i386
Notes:
Code committed to the branch has booted to multiuser
on at least one system.
Not guaranteed to compile against mainline since -current
may have changed incompatibly with the last branch update;
use "cvs update -D" to roll-back the rest of the tree to match.
Please get explicit permission from the maintainer
before each commit, or your changes will be backed out.
Other tags starting with sommerfeld_ are private to
the developer and are guaranteed to be unstable.
Only the maintainer should move tags.
Note that this branch uses a DIFFERENT scheme for
syncing with the mainline. the maintainer uses some private
scripts for keeping them in sync; if you make commits
to the branch to "resynchronize" things, you'll
probably do it wrong; instead, ask the maintainer to
resynchronize things.

issues with the branch.

R4400-with-L2.
* R4600/R5000 (cache_r5k) -- shin@NetBSD.org
has committed fixes to this code.
Confirmed working on R4600 v2 (SGI IP-22 with
no SysAD L2 cache).
Confirmed working on RM5260 (Algorithmics P-5064).
* TX39 (cache_tx39) -- uch@NetBSD.org has
committed fixes to this code. Awaiting
confirmation that it is working properly.
* R5900 (cache_r5900) -- uch@NetBSD.org has
written this code and tested it on a
PlayStation 2.
The following ports have been updated to compile (and
use optimized-for-processor bus_dma routines). Those
that have been tested and work are marked with [WORKING].

Branch: wrstuden-devbsize
Description: Modify buffer cache to deal with different devices having
different block sizes. Also DEV_BSIZE would go away.
Status: Terminated
Start Date: Aug or Sept 1999
End Date: 1 Apr 2000
Base tag: wrstuden-devbsize-base
Maintainer: Bill Studenmund <wrstuden@NetBSD.org>
Scope: kernel
Notes: No longer active due to lack of time, and introduction
of UBC. In terms of UBC, the primary cache for
file data is the VM cache, which needs to operate
in terms of VM pages. As no existing device has native
pages the same size as our VM pages, there already is
a mapping going on between the VM system and the
underlying blocks. So it would be easier and cleaner
to adjust that to deal w/ different block sizes.
Also with UBC, all i/o is in terms of bytes at an offset
with a certain length, so the exact block size isn't a big
deal.
Any other wrstuden-devbsize tag may (and should) go away.

How to adapt a port?
- unify cpu_switch, cpu_exit, cpu_switchto into
a single cpu_switchto. see cpu_switchto.9.
- implement cpu_idle. see cpu_idle.9.
- add a flag argument to cpu_need_resched.
handle RESCHED_IMMED flag, which means "cause a preemption
as soon as possible." eg. in the case of MULTIPROCESSOR,
send an IPI to the target cpu.
- "curlwp == NULL" is not a valid check for idle state anymore.
use "(curlwp->l_flag & LW_IDLE) != 0" instead. curlwp is
almost always non-NULL, with exceptions like early on boot.
- remove idle pcbs.
- (if MULTIPROCESSOR) tweak processor trampoline code.
- (if MULTIPROCESSOR) call mi_cpu_attach when attaching
secondary processors.
- (if schedhz!=0) call schedclock regardless of the value of
curlwp.
- of course, update MD users of scheduler/switching API.

- Audit MUTEX_CAS() and RWLOCK_CAS() uses
to see of membar_enter() is required here.
- Talk to ad@ -- figure out of non-atomic
mutex / rwlock release is actually safe.
arm - Consider using a RAS technique like
MIPS uses for _lock_cas() and the mutex
stubs. Possibly do more than one atomic
op as a RAS. Possibly implement mutex
stubs using the technique.
m68k - Need to do 68010 support.
i386 - Need to change when x86_patch() is called
so we can test ncpus.
powerpc - Figure out if we need barriers in the
atomic ops themselves (hopefully not!)
x86_64 - Need to change when x86_patch() is called
