[Samsung Galaxy Tab Plus] Entropy512:
Did you get any useful /proc/last_kmsg dumps of SoDs? Enabling wifi may only be making a difference because of the wakeups.

That said - I am completely shocked that Broadcom's drivers are open source and the ar6000 driver isn't. I've lost a lot of respect for Atheros AND for Samsung over this. I can understand if it's BSD - but seriously, what trade secrets could Samsung have in a freaking Atheros driver, and for something like this, what possible business reason could they have for witholding source for that ONE module? It's freaking stupid.

I was hoping that they'd start becoming more developer-friendly as a result of hiring Cyanogen, but they're being asshats at this point. They donated a device to Codeworkx (or someone else on Teamhacksung) to get CM7 ported, but have not given him a shred of assistance with the porting effort. Basically, trying to get "Supported by CyanogenMod" credits without ANY significant effort.

As much as I hate Sony - SE seems to be doing the best of any manufacturer in terms of supporting people doing platform-level development.

Edits:

You know, this is proving to be a clear and recurring pattern. I have never seen XDA get anything useful out of SamsungJohn for example, all he does is come over, tease us with something, and never follow up.

Over in the Captivate forums - he came in and posted that source code was out, then left without any followup - by the time he made this announcement, people had already found the source and were working with it - http://xdaforums.com/showthread.php?t=997098

He then came and teased us with the Samsung Developer Program - guess what, it provides NOTHING for developers doing platform work - http://xdaforums.com/showthread.php?t=1392847 - John also didn't come and respond to any of the feedback

Prior to that there was the Samsung Developers Conference tease - http://xdaforums.com/showthread.php?t=1291758 - nothing useful came out of this for anyone doing platform work. In fact, John just dropped off the face of the earth, I'm assuming that not a single person from XDA actually was brought by Samsung to the event, otherwise there would've been a followup/debrief post. Anyway, the "big announcement" was just the Galaxy Nexus release announcement. Big deal - that's a dev phone because Google forces it to be one, it's more of a Google product than a Samsung one.

http://xdaforums.com/showthread.php?t=954896 (and many similar posts) - He just crossposted to a ton of forums saying something awesome was coming. Something awesome never came. The linked thread from many of his posts doesn't even exist. Actually, most of his 67 posts are just crossposting this tease - NOTHING ever came out of it.

http://www.engadget.com/2011/06/08/samsung-shows-affection-to-cyanogenmod-gives-its-devs-a-free-ga/ - As a PR stunt, Samsung threw a Galaxy S II over the wall to one of the CM developers. Without a doubt, Dan Hillenbrand (codeworkx) and Atin Malvaya (atinm) have not received any support from Samsung since Sammy threw a device over to them. The GSII is likely to be codeworkx's last Samsung device, he has become so frustrated with Samsung (Check his posts in the CM9 thread for I9100). Compare this to Sony Ericsson's effort here - http://blogs.sonyericsson.com/wp/2011/09/28/sony-ericsson-supports-independent-developers/ - They have given FreeXperia MASSIVE amounts of support, and it shows - http://www.cyanogenmod.com/blog/sony-ericsson-xperia-support

imnuts07 asked for some help regarding Droid Charge kernel source issues - https://twitter.com/#!/SamsungJohn/status/152835654303236097 - All he responded with was "how can we help" - no further response, imnuts07 didn't get anywhere until jt1134 gave him some pointers. (It turned out to be more proprietary module vermagic bull****...)

After all this, it's clear that with regards to platform developers, Samsung's intent is to do the bare minimum to meet their legal obligations with the GPL and no more. Even source code which they COULD release and have no valid reason for withholding is withheld if they are able to (such as the ar6000 module source code). I thought that the Galaxy S II was a step forward towards devices with 100% open source kernels, however it is clear that the GSII was just a fluke. I'm getting sick and tired of dealing with module vermagic headaches. I've spent at this point a few hundred hours of my spare time working on improvements to various products of theirs(maintaining kernels for three different products - Samsung Infuse, AT&T Galaxy S II, and Galaxy Player 5.0), and their consistent message back has been "go away, screw you, stop bothering us".
