sticky boy: not been able to get wifi working have init.rc perms and other stuff but get an illegal wifi state. do we have to use the nl80211 kernel interface ?
<ohanar>
cyberkryption: no we do not have to, but I have had no better luck with the WEXT interface
<cyberkryption>
ohanar: i can get it to compile with the WEXT interface telling it to use 0.6 version of the supplicant it does not compile with 0.8
<ohanar>
you might need some modifications from linaro to get it to compile with 0.8
<ohanar>
I know I've done it at some point in the past, but it was less than fruitful, so I just kept the nl80211 interface
<cyberkryption>
ohanar: is there any leaked source code for ar6003.ko about ?
<ohanar>
sure, there is ar6000 code out there, but nothing that works with our tabs as far as I know
<ohanar>
also, samsung has abandoned it
<ohanar>
the ics release for the tab 7.7 uses the ath6kl module
<cyberkryption>
ohanar: have they released ics for galaxy tab 7.7 ?
<ohanar>
well for the 3g international model they have
<cyberkryption>
ohanar: i have the uk/europe model i believe, can't we take the modules firmware from that ?
<ohanar>
you have a tab 7.7 or tab 7+? the kernels are not compatible between the two
<ohanar>
if you are looking for wifi firmware, the chip is the same between the two, so the same wifi firmware should work between the two
Rebellos has joined #teamhacksung
<cyberkryption>
ohanar: is up on a samsung server somewhere i can download it from ?
<cyberkryption>
ohanar: my thinking was to grab the firmware, kernel , wifi kernel module etc then put them in the right places and try a build. what do you think ? will the samsung kernel break other things in the rom ?
<ohanar>
you will need to repack the kernel with an appropriate initramfs, normally the build system does this, but I haven't been able to get it to work properly for some reason
<ohanar>
it would also only work on the p6800, and potentially on the p6810
<cyberkryption>
ohanar: i have the p6200 so just have to wait for samsung then?
<ohanar>
if you want, stickyboy and I will probably switch kernels when the kernel source for the tab 7.7 is dropped; the smdk4210 kernel doesn't really have full enough support for our devices, and back porting everything we need is way more work than bringing forward the changes that we need
<cyberkryption>
ohanar: are samsung pretty good at giving their kernel sources out ? It would make sense to use their sources because we would not have to compile wifi driver!
<ohanar>
hopefully we will get in the next two weeks, that seems to be their typical time frame
<cyberkryption>
ohanar: is there much work into getting the samsung kernel sources into the build tree?
<ohanar>
we would still have to compile the wifi driver, and it probably still won't work
<ohanar>
I know that samsung has modified wpa_supplicant for the ath6kl module, you can tell by the lack of command line arguments given to it in the init.rc for the ICS release
<cyberkryption>
ohanar: wont samsung have to release their mods ?
<ohanar>
if they decide to actually obey the law, they will release the changes for wpa_supplicant (since it is licensed under the gpl, unlike most of android), but they likely won't
<cyberkryption>
ohanar: then in order to get working wi-fi you have to use their binary kernel ,kernel wifi modukles / wpa_supplicant etc in the build system ?
<ohanar>
no, we will have to reverse engineer their changes to wpa_supplicant
<ohanar>
the changes to the wifi modules will be in the kernel source code (since they are using the ath6kl module this time around)
<cyberkryption>
ohanar: i was going to extract their binary blobs from the ics update when it comes and use product copy files to put them in the right place. I would need to perms right and put init.rc mods as well
<stickyboy>
We can't use their blobs.

stickyboy: at the risk of askking a noob like question,when i built the NI rom i used used a compiled kernel form NI source with their kernel module, wpa supplicant and cli put in the right places using product_copy files.Will a similiar approach not work ?
<stickyboy>
Don't worry about noob questions hehe.
<stickyboy>
We can't use their kernel module because our kernel sources are completely different, and our userland stuff like wpa_supplicant doesn't have their changes.
<cyberkryption>
stickyboy: extract their binary kernel rom the boot image put that as a prebuilt kernel into the source, extract and place other blobs etc including wpa_supplicant from ICS update.More of a hack i know
<stickyboy>
Maybe. I don't know enough to say yes or no.
<cyberkryption>
stickyboy: this was my self taught way of hacking wi-fi to work last time after some frustration but i did learn some stuff eventually after many failed builds
<stickyboy>
But were you hacking on a stock ROM or an AOSP-based ROM?
<stickyboy>
I had a friend with an Adam. Sad device. :)
<cyberkryption>
stickyboy: still got mine, i learnt a lot. It was just a pity that NI being a small startup could not support it and relied on their community which caused some friction. Having said that it has decent hardware for the time
<stickyboy>
Maybe it would work to replace the kernel in the build tree with the Samsung ICS one.
<stickyboy>
And then use their blobs.
<stickyboy>
I dunno.
<ohanar>
you would have to use our initramfs
<ohanar>
and probably other stuff would break, like some usb gadget stuff
<stickyboy>
CM build system allows pre-compiled kernels. It's deprecated though :)
<cyberkryption>
stickyboy: you can use it as a fallback according to cm wiki

there's one in Sprint SGS3 source
<Rebellos>
Gonna check it out, maybe anything thats interesting me.
<xplodwild_work>
it's only a few configs/scripts
<xplodwild_work>
though I don't think there is much more needed to compile kernel for chrome os
<xplodwild_work>
no idea if it's for SGS3 either

Ah, I see. And what's the surprise btw? ;d
