Re: [Madwifi-devel] ANNOUNCE: SFLC helps developers assess ar5k (enabling free Atheros HAL)
Just in case you want to experiment, i have a working port of ar5k
that works on madwifi-old before the BSD - HEAD merge...
well i'm no good programmer (yet), i did what i could (i'm sure those
define macros are nasty for most people :P) and hope that helps...
you can git clone from the following link
rsync://rsync.ath-driver.org/gnumonks_users/mb/openhal.git
I'm working with the following madwifi revision...
svn checkout http://svn.madwifi.org/branches/madwifi-old -r 1142 madwifi
Don't forget to remove the ending ) in line 175 at
net80211/ieee80211_radiotap.h ;-)
Also you'll need to do some modifications to make it work with newer
kernel versions (MODULE_PARM stuff in if_ath.c)...

See README for more details
I haven't looked much the MadWiFi code since then, perhaps you can
help in making ar5k work with newer madwifi versions + improve it's
functionality to help both linux and OpenBSD.
(The name OpenHAL came from John Bicket's initial port)
Happy coding ;-)

Well, we have various support channels (an IRC channel besides two
mailing lists, for example) that you are welcome to make use of in case
of problems :)

No, I'd personally reject madwifi not because of the HAL but because it uses the net80211 stack [1]. We don't need another 802.11 stack in the Linux kernel, of course. But since the Devicescape people have already ported madwifi to d80211 (see David Kimdon's announcement on netdev on Oct. 17th), that appears to be a valid path to follow and at least some of the work has already been done. If the HAL bits were ported to ar5k and folded back into the driver, I think that would be a great start. Dan [1] nothing against net80211; it's a fine stack. But There Can Be Only One, if just for sanity's sake. - To unsubscribe from this list: send the line unsubscribe netdev in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
Re: [Madwifi-devel] ANNOUNCE: SFLC helps developers assess ar5k (enabling free Atheros HAL)
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 OpenBSD seems to have a working driver (if_uath.c) for these USB WLAN sticks. 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.
