I've set up the suggested branches, with slight changing to the proposed
names:

* http://svn.madwifi.org/branches/madwifi-old-openhal (based on r1142)
* http://svn.madwifi.org/branches/dadwifi-openhal (based on r1827)

Neither of them has received any modifications yet, they are basically
copies of the mentioned revisions. I'm currently lacking the time to
import Nick's work into the madwifi-old-openhal branch, for example - it
would be nice if someone else could work on that.

The MadWifi project happily provides any interested party access to the
resources we have at hands - including (but not limited to) r/w access to
the repository, an account for our Trac (used to manage tickets for bugs,
patches, ...), e-mail,  Let me know if you need something in that
regard and I'll try to get it done. We'd love to support these efforts
where possible.

Bye, Mike

the more people help, the faster will the goal be reached.



From what I understood the "... once the hal issue is resolved" part of
David's mail refered to exactly that question.

Ok, I don't know what "The HAL Issue" (tm) is.


You referred to the archives where that exact "issue"(s) (binary-only, 
non-free, no sources, unwanted level of abstraction) has/have been 
discussed in lenght, but you claim you didn't have a clue what David was 
talking about? Come on.

Re: [Madwifi-devel] ANNOUNCE: SFLC helps developers assess ar5k (enabling free Atheros HAL)

2006-11-16 Thread Michael Renzmann
Hi.

> At least, this way we have a chance to get USB working as well (See
> http://madwifi.org/ticket/33).

It's not the HAL that prevents MadWifi implementing USB support. Replacing
the binary-only HAL with OpenHAL and/or dissolving the HAL functionality
in the driver source does not get us any closer to a working support of
USB sticks.

Quoting Sam Leffler on that topic:

=== cut ===
The Atheros-based USB devices work rather differently from the
cardbus/pci cards.  In particular there is no hal; instead there's an
onboard processor that runs the hal and implements a special protocol.
This means you can reuse some of madwifi but you also (probably) need to
redo the code some to break out different interfaces.  It's not a simple
project.
=== cut ===

see: http://article.gmane.org/gmane.linux.drivers.madwifi.user/5380

Which, at least for some sticks, requires a not freely distributable
binary firmware blob, by the way (see:
http://archives.neohapsis.com/archives/openbsd/cvs/2006-09/0233.html ).
Nevertheless, it would be nice to have that driver ported to Linux.

Re: [Madwifi-devel] ANNOUNCE: SFLC helps developers assess ar5k (enabling free Atheros HAL)

2006-11-16 Thread Michael Renzmann
Hi.

> Just in case you want to experiment, i have a working port of ar5k
> that works on madwifi-old before the BSD - HEAD merge...

Just to mention it: madwifi-old is no longer officially supported, and is
a bad ground to start working on IMO (at least for anything that goes
beyond a quick test).

Interested parties should start from trunk instead (which is at r1809 as
of now, by the way), or, even better, from the DadWifi branch. However, it
will require some work to get the OpenHAL working in either of them. I
suggest that related questions and discussions should be directed to the
madwifi-devel list, since they might be of little interest (yet) on netdev
or lkml.

The MadWifi project is happy to provide resources (such as r/w access to
our Subversion repository) to support these efforts, by the way. Please
contact me offlist for details.

Sorry, that was my bad. I thought that the Devicescape code found its
way to the kernel (didn't follow the discussion some months ago too
closely). Although I think there probably are better alternatives to the
802.11 stack that is in the kernel right now, having a central 802.11
stack at all is a great improvement that should be used where possible.

> Encouraging otherwise hinders continued wireless progress under Linux.

That depends. If the encouraging is about an alternative, more complete
and superior 802.11 stack for Linux which could be integrated with less
effort than extending the existing code, that should be worth to talk
about. 

Please note that I'm not refering here to any of the related suggestions
which have been made during the past months - it's a general statement.

Or, in case there is some unknown objection to the mentioned code: use
the 802.11 stack that comes along with MadWifi, which provides things
like virtual interfaces (for multiple SSID support on one physical card)
and WPA support.

Although I'm a bit biased towards MadWifi, I'd second your suggestion to
make use of the Devicescape code. The benefit of having a fully-blown
802.11 stack in the kernel that drivers can make use of has been
discussed before, so I won't go into that yet again.

I once made this working with the bridging code. Unfortunately I can't
find the mail that described the necessary changes (I asked about a
similar setup on the bridging ml several years back). It was something
like "change the bridge in a way that it doesn't drop packets with out
MAC address from forwarding it to the enslaved devices. Just a few lines
had to be changed, and it worked great with Lucent WaveLAN cards out of
the box.

If such an setup would be ok for you, I'd try to find the print-out of
the mail in question. I'm sure that I have it somewhere here.
