Linux Wireless Mini-Summit -- Ottawa -- July 22, 2008

Linux Wireless Mini-Summit -- Ottawa -- July 22, 2008

[John W. Linville]

The third Linux Wireless mini-summit will occur on Tuesday July 22,
2008 in Ottawa, just before the Ottawa Linux Symposium.  OLS is
generously supporting Linux mini-summits by providing the room and
projector (http://www.linuxsymposium.org/2008/minisummits.php).
Several vendors are supporting the event by sponsoring their own
employees to attend, and Canonical and Intel have both helped with
travel funds for key community participants as well.

Although it is already a bit late, I would like to re-open discussions
on our agenda for the meeting.  Based on current upstream topics and
those persons whom I expect to be attending, I have cobbled together
an agenda proposal below.  Please review it and feel free to suggest
amendments or alterations, or to elaborate or ask questions about my
proposed schedule of topics.

I look forward to seeing many of you in Ottawa!

John

P.S.  If you intend to attend the event in Ottawa, please send me a
private reply to this note -- even if you believe that I already know
that you are coming! :-)

One more topic would be probably
 power management/power save - connection to system power/power supply
(Battery/AC)

brief discussion about AP mode current and future plans would be
appreciated, maybe as part of the MLME topic.

I'm also very interested about this. mac80211 is lacking any support
for Power Save Mode and I think we should fix that. At least having an
interface to enable and disable PSM would be a start, but we could go
even further than that.

I'm just worried if one day is enough for us. The agenda is getting
quite long already.

There should be plenty of time to continue discussions after (or even
before) the mini-summit since I would assume most people stay for OLS.
For example, I will be in Ottawa for the full week (July 18-27) and
will be available for discussions related to wireless topics both
before and after the mini-summit itself.

Yes, you are right. I guess there are vacant rooms during the OLS
which we can use, if needed.

I'm also very interested in any discussions. I will be arriving on the
20th and leaving on the 27th of July.

Hello,
 Linux wireless is, without any doubt, a very important subject.
Many people show interest in it.

It is good to hear that the third Linux Wireless mini-summit will
occur at OLS, which will give opportunity to  many people (which some
of them don't know much about linux wireless) to attend it (whereas
the two last wireless mini-summits were not part of OLS, as far as I
know).

I want to add that It would be great if part of it (or hopefully, all
of it) will be videoed and put on the web. I am sure that many
(including me) will be glad to watch it. I am sure that making an
effort like this is important and is of interest for the linux
wireless community.

Regards,
Mark Ryden

We've seen initial patches that add a bit of infrastructure, but aren't
using these things yet.

Hope to submit all the patches before symposium.
The whole package is already visible in iwl5000 branch of
iwlwifi-2.6.git Need to clean it up and submit.

Maybe something about testing? Or I'll do a testing brainstorming
session after dinner.

Obviously, testing at orbit never worked out, but it'd be good to have
_something_ other than everybody testing their thing locally. Ties in
with the virtual hardware, maybe?

I'm also looking for easier bug reporting for unexperienced users
maybe some uevent/HAL popping to application and emails it out/. Not
sure really how to handle this and not create spams. I'm just
expecting more real 'end users'.

Please add a note about WiMAX. We'd like to give a quick intro to the
technology and the infrastructure work we are doing for it.

Some other topics which might be of interest/good to include:
- New chipsets needing drivers (SiS 16x, Marvell, etc.)
- Radiotap enhancements
- Userspace MLME: Plans and status

I have no idea what to discuss about non-existing drivers, really.
Something like: "Do we need that driver? Everyone votes YES and is happ=
y"?

> - Radiotap enhancements

What radiotap enhancements specifically? If it's just a field or a bit
to add, just mail the radiotap people. I think there's no need to discu=
ss that
(except for with the radiotap people on their mailinglist).

Already on the list.

Maybe during the week we could organize some hackfests to work on the
Marvell/SiS/etc mac80211 drivers?  Everyone bring their favorite
non-working Marvell 88w83xx card and we make mrv8k our bitch or
something like that.

FYI...

Lennert Buytenhek and I are writing a GPL driver for mv8300 class of 
Marvell WIFI chips right now, present and future versions. This is 
Marvell work as we work for Marvell.  I have access to firmware sources, 
etc. but obviously cannot share them.

We both will be in Ottawa next week.

Great!  Lets definitely sit down and talk then.  There is already some
GPL-ed source code for 83xx chips out there but it always used net80211=
,
not mac80211.  So the mrv8k effort is meant to write a mac80211 driver
for 8310/8335/etc and perhaps TopDog chips too since they don't seem
that much different from a driver perspective.

Some of the issues with the current Marvell 83xx GPL drivers that have
gotten out are (a) code style, (b) lots of commented out stuff that's
never used, (c) OS abstraction that's unnecessary on Linux, (d) doesn't
use mac80211, and (e) uses private ioctls.  So hopefully you're writing
a new 83xx driver from scratch :)

We cleaned up a lot of stuff for the OLPC 8388 libertas driver, but
unfortunately we never were able to get the Marvell 8388 team onboard,
and so they just went off and kept working on their driver and didn't
really move the upstream libertas driver forward at all.

=46orgot to finish this last bit...

So hopefully that won't happen here, since this would be pretty much th=
e
same situation up to this point.  Ideally you can get the internal
Marvell developers onboard so we're all working on essentially the same
bits, exactly like Intel has done.  Yeah, they develop on private trees
internally but at the end of the day, their base code is the same
upstream base code everyone else uses.

Yes, this is all from scratch.  The objective for this work is to be 
"mainlinable".

Obviously; this was just an observation about the last time we got a
wireless driver from Marvell.  I expect it to work out rather
differently this time simply on the strength of your and Lennert's
track-record, but if it's really just you two guys and you don't have
buy-in from the actual hardware and software teams inside Marvell, it's
hard to see how this wouldn't just happen again.

BTW, any chance on putting up a git repo somewhere so others can poke

I think you just listed exactly the problems with all vendor WLAN
drivers. 

I think Intel is the only expection here. Is there anyone else?

And it always seems that this is the only viable way to solve it :)

Re: Linux Wireless Mini-Summit -- Ottawa -- July 22, 2008

I think that probably the most burning topics were a little diminished
in our agenda, and should be put higher:
- cfg80211/nl80211 - much of the current wext begins to fall behind
the emerging capabilities of the mac80211 and moreover - from future
abilities and needs of future fullmac devices. The functionality and
ABI to userspace must be finalized as soon as possible. The status of
this is very unclear and should be treated more thoroughly, and it
seems it can't be shared with 5 other topics in less than 2 hours.
- fullmac support - seems to be very relevant in the next couple of
years with the integration of wifi into low power devices running
linux.

I think that these two topics should take precedence over other topics
that although important consume more time in the agenda, and are
currently less likely to have impact on the average users such as 11s
and 11w.

it would be good if these topics will get substantial time slot in the agenda.

FWIW, I listed this one first under Future Work.

Not sure exactly what you mean with this one.  Are you talking about
the lib80211 line item?  Or enhancements to the mac80211 component
to support full(er) MAC designs?

There are lots of items listed, and I'm not sure we will cover all
of them.  If there are any that you would like to suggest be dropped
completely then please do so.

That said, I don't think we have enough time for real working sessions
on Tuesday.  I think it would be better just to touch on a variety
of topics that can benefit from some face-to-face discussions.
>From that perspective, I think some status reports and some brief

I'll post a revised (mostly just augmented) agenda proposal today.

I hope just lib80211.  We shouldn't be extending mac80211 to fullmac or
quasi-fullmac parts.  But we can certainly share a lot of stuff.
lib80211 is where I see any additional fullmac effort going.

Just a minor point wrt. lib80211: I see little use in creating yet
another module since hopefully soon enough fullmac chipsets will bind
cfg80211 anyway so all of that stuff might as well be in there.

REVISED AGENDA -- Re: Linux Wireless Mini-Summit -- Ottawa -- July 22, 2008

[John W. Linville]

I revised the agenda based on the feedback from last week.
Most changes are fairly minor, although I moved the vendor/distro
round table after lunch to give us a chance to cover some in-progress
work beforehand.

As I mentioned elsewhere in the thread, I don't think we have enough
time for work sessions on Tuesday.  As others have pointed-out, there
is plenty of time for extended discussions during the days at OLS.
So I think we should keep Tuesday for more high-level design and
development process discussions.

Feel free to volunteer to cover any of the listed topics.  Further
suggestions to alter or augment the agenda are, of course, still
welcome as well.

Thanks!

It might make sense to do these the other way around since 11n depends
on the MQ stuff. I can talk about davem's recent changes that remove
most of the code, but other than that I think we're pretty much set.

Both of those are pretty much stalled now, apparently because I was the
only one investing time into them and am no longer doing anything at the
moment. I can give a five-minute overview over what we need/want for
each of those I guess.

I believe as WEXT limitations are more visible mainly in the context
of fullmac chips.
A discussion that defining new interface or it course will be very
important. cfg80211 came a bit ahead of it's time and I  believe
actually now we can spin it again.

I adjusted the times based on the schedule for lunch and coffee breaks
from the OLS crew.  I also adjusted the length of some slots, and
move the BoF/Break-Out/BarCamp section before adjourning for dinner.

I'm still looking for more/different topics and for people to
explicitly claim the ones on the list...speak up!

Just to emphasize, please note the location.  The mini-summit will
be held at Les Suites, _not_ at the Congress Centre.

I'll cover this. If we can't cover this well in the time frame
provided we can discuss this over the course of the week in impromptu
sessions.

A couple I can think of:

* Compat-wireless, this can be discussed after new MQ patch. We may
have to freeze mac80211 for old kernels for compat-wireless after the
MQ patch goes through and only leave in it fixes moving forward. This
consideration is because porting the MQ patch may be very difficult to
maintain. It was expected though that the first MQ patch could not be
ported though so we'll see, we just might be able to port this
properly. We can talk about this further at the summit.

* Testing -- lets get serious about automation of testing. The Orbit
grid is still available, we just need to put together scripts and test
scenarios.

* Rate control cleanup -- this needs to a good review and cleanup.
Probably not high on our priority list though. We can talk about this
further during the "rate scaling algs" section on the agenda.

RE: Linux Wireless Mini-Summit -- Ottawa -- July 22, 2008

[Joerg Pommnitz]

Hello all,
another topic of interest to a substantial minority came up
a few days ago: "Link specific statistics in Adhoc-Mode",
see http://marc.info/?l=linux-wireless&m=121492872932293&w=2

Access to per node statistics would make routing decisions
in user land mesh networks more efficient.
