Hi!
some months ago, i saw the presentation of Johannes Berg in PDF, but now it?isn't available, probably because it's very old.
This slides will be updated to a new release?
I have this slide?and in page 5/35 (2009-02-26) there is the "Architecture - planned". This is the actual architecture or there are some?differences?in 2015??If yes, where i can find the new version of this page, with a little diagram?
Thank you very much,
Stefano
Thank you very much Arend, in particular for the documentation.
If i understand correctly, the levels are:
userspace
nl802111
cfg80211
firmware
No mac80211 because is a fullmac.
Correct?
Thank u, Stefano.

Hi Stefano,
The bcm4339 is supported by the brcmfmac driver and is a cfg8211-based
driver aka fullmac device where the 802.11 stack runs on the device. I
did write up some stuff about the driver internally, but we can consider
putting it on wireless.kernel.org under creative commons license.

Arend

There's also brcmfmac internal code translating cfg80211 into firmware
messages, but you probably know that.

Yes.

Ciao Stefano,
Perhaps Johannes can post a current overview diagram on the Linux
wireless wiki (if you share with him which diagram you want to be
updated).
In terms of vendor-specific architecture, and how it fits in, Kalle
Valo posted a high-level diagram for ath10k:
https://wireless.wiki.kernel.org/en/users/drivers/ath10k/architecture
Are you mainly interested in the architecture of vendor-agnostic upper
layers or a description of a specific vendor driver?
kg
Oh thank you.
Yes. This can be very useful.

A while ago, i have written about the generic linux wireless
architecture for my blog. It might be helpful.

Hi
I prefer a generic version, without specific things, like this one: h**p://postimg.org/image/hfkpjt3ux/ created by Johannes Berg.
And, if available something for the broadcom chip bcm4339.
Thank you.

Ciao Stefano,
Perhaps Johannes can post a current overview diagram on the Linux
wireless wiki (if you share with him which diagram you want to be
updated).
In terms of vendor-specific architecture, and how it fits in, Kalle
Valo posted a high-level diagram for ath10k:
https://wireless.wiki.kernel.org/en/users/drivers/ath10k/architecture
Are you mainly interested in the architecture of vendor-agnostic upper
layers or a description of a specific vendor driver?
