|
|
# 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.

Branch: ad-audiomp
|
|
Description: Add MP locking to the audio drivers
|
|
Status: Active
|
|
Start Date: 28 February 2007
|
|
End Date:
|
|
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.

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

|
cpuswitch.S which would otherwise make merging the
|
|
nathanw_sa branch difficult.

Branch: gmcgarry_ctxsw

Description: Separate scheduler from context-switch code

Base Tag: gmcgarry_ctxsw_base
|

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

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.

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.
|

|
Branch: yamt-kmem

Description:
|
|
- separate kernel va allocation from kernel fault handling.
|
|
- make kmem_alloc interrupt-safe.

Notes:
|
|
todo:
|
|
- investigate if PMAP_PREFER equivalent can be done
|
|
with vmem_xalloc. find a tester with hardware for it.
|
|
- g/c replaced code, including kmapent and malloc.
|
|
- consider to remove other submaps. eg. mb_map

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
|
|
...

all - Need to replace mb_*() with membar_*().

|
- 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
|
|
so we can test ncpus.

developers are welcome to commit to this branch.

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.

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.
