Devs who look at ICS Source. Look here! - HTC Amaze 4G

So we have a portal writer that has written multiple articles on the stuff I made and the stuff we've been doing. He asked us for more info on the Amaze source so he can write about it and help us get more recognition. Don't believe me? Look for yourself.
https://twitter.com/PoorCollegeGuy/status/222516466711396352
So can you say what new changes have been made. Did HTC make it harder on us to hack it? Did they not release anything we need? anything so we can get this published. Write it all here and I'll pass the link to this thread to him when we get responses.
Please, only respond here with information on source. NOTHING ELSE! I want to keep it nice and clean here.

Well my understanding is the wi-fi drivers are there they just commented out what we need to build it and a compat-wireless modules that they didn't include but i found another way to get it working just fine

Wifi is working using the existing modules that HTC provided. Currently we are still looking for a way to get the modules that are compiled by the kernel to work.

Yeah, it appears that they commented out the building of the wl12xx drivers, but the stock ICS does have wl12xx modules. The evidence (commentd out makefile, presence of compat.ko, wl12xx.ko, wl12xx_sdio.ko, etc.) points to HTC using a version of compat-wireless drivers, but which one, I don't know. I also don't know if HTC made any modifications to the wireless drivers, but if they did, they'd be obligated by the GPL to release the updates.
Since the tweaks sportsstar used to get wifi work in his kernel worked, that means that we should have everything we need on the kernel side of things, we just need to get and build the proper version of compat wireless. I also wonder if we need to match the version of compat-wireless with the binary firmware blob from TI. In all the work building different versions of compat-wireless, it could be we also need the proper firmware.

The only problem with the current tweak to use existing wifi modules is that I think it may be breaking other functions. Not sure about this yet though.
When I get my amaze this week my plan is to try a few different firmware from ti. I think you're right about needing to swap out the blobs. If this is the case then it should make things pretty easy.

Ok, since this is a generic thread about ICS source, I'm moving all of my kernel ramblings here, instead of taking up space in Kozmik's kernel thread.
Anyways, I ran modinfo on all the modules in the T-Mobile ICS update. Here are the results:

They are all GPL with the exception of compat.ko being dual licensed. I don't think that should be an issue (ie. doubt HTC had modifications) as I think that modules function is to interface with the other drivers (wl12xx, etc.) to the current kernel version. The rest are GPL and therefore HTC must release the source for it.

I'm not perfectly clear on dual licenses, so it should be posed to FSF, but from what I understand, it allows the code to be compatible with GPL and BSD projects. However, if used in a GPL project, I believe the GPL portion of the license is what takes effect, since the BSD portion is not compatible with the GPL project.
A quote from Linus Torvalds:
"This is no different from the fact that we have some drivers that are GPLv2/BSD licensed. Within the kernel, they are GPLv2. But on their own, you can choose to use them under the BSD license, make your changes to them, and release them commercially. And correct - I cannot (and neither can anybody else) then accept those *non*GPLv2 changes back."

I'm having trouble with "on their own" and "within the kernel".

I guess this simply means that if the modules are released within a kernel like a single entity then it has to be GPLv2 but if the module's source is not released as "part of the Linux kernel" but just like "a module to make that piece of hardware working with the Linux kernel" then it can be released under BSD license.

The only module that's dual licensed is the compat.ko module, not the actual driver files, which are all still GPL. I assume that if HTC did make modifications to compat.ko, that they'd have to update the license to say BSD and not BSD/GPL. I believe all the code in compat-wireless is from the kernel itself, just a newer version, that you compile for an older kernel.
On another note, I am supposed to get a call from HTCdev escalation on the GPL driver issue. I wonder if the person who will call me will actually know what's going on, or if it will just be the generic customer support escalation team.

I'm still fuzzy on dual licensing, but seeing that HTC released the module as dual licensed (GPL/BSD), doesn't that allow the user to decide the license? So, if you decide that it is GPL, shouldn't they release the source for it?

Well, becuase 6pm eastern is within the window of 8-11pm eastern I told them to call, I missed their call. I'll try calling them tonight.

Just a heads up, we are going to have an article written on this soon. Our portal writer is going fix up some small kinks and then we will hopefully have more exposure and support.

I ended up talking to HTC this weekend. It was as I expected, some guy who couldn't really do anything, but he listened and wasn't really all that hostile. He said he'd pass it on to the dept responsible. I told him that HTC was oblicated to release the source for all GPL code and that they need to release it the day the executable code is in the hands of customers. We'll see if it leads anywhere.

But tiwlan_drv.ko and tiap_drv.ko doesn't get built while compiling the kernel

My response from HTC was that they were using proprietary drivers.
Even still since the source is available from Texas it should be possible to use their code if we swap out the firmware. May have to do some calibrations and build our own WPA_supplicant though.
