BCM4329:

Now for someone to figure out how this builds. Not sure if this helps.

Funny how this pops up just a day or 2 after you call them out on not being GPL compliant.

I know right, but I'm not fussed lulz should be a good read, in other news I broke some more of the bootloader, will post the details in the detailed info thread

Took a quick look and compared to AOSP, and this is just the Eclair release of the BCM4329 driver, version 4.218.161.0

My Singapore firmware actually uses 4.218.205.0.

I don't even see it http://android.git.kernel.org/?p=platform/hardware/broadcom/wlan.git;a=shortlog

Feeling that this doesn't actually matter...

Basically I got as far as building a module dhd.ko, but I don't know what to do with the stack/back trace after it loads a whole bunch of stuff.

Can we request Huawei for a Makefile, or do we do this by trial and error? Also, is it okay for us to request the sources distributed for the ones associated with our firmware?

 

[Balcora]

We could create our own; but as for the module being the old one; we can email them regarding breach of GPL for not releasing up to date source.

Some companies seem to believe that "releasing source" means they can just release the pre-alpha code and that negates their GPL dues.
But no, its GPL and specifically with the kernel, its supposed to be decent availability of the active release code, they don't necissarily have to give experimental code, but once it is released as a compiled module for use... i.e. in the S7, it needs to be made available.

 

[xaueious]

I managed to compile dhd.ko from copying the BCM4329 off cm-kernel and tweaking the Makefile, but I get a stack/back trace which I do not know how to deal with.

Emailing Huawei first...

 

[rictec]

anyone tryed download and compile the broadcom wifi driver that was put online ?

[jerliu]

What is the broadcom driver for?

 

[l_n]

It's a wifi chipset.

 

[xaueious]

They got use this now: S7_Broadcom_BCM4329_4.218.205. 0_Open_Source
IDEOS S7 - Huawei Device Co., Ltd..

Still probably cannot get it to compile. I asked pershoot and he told me to look at the GPIO stuff, which I do not really know how to start with.

Will download and inspect anyways.

This source code was not on AOSP, so maybe this has what we need.

 

[xaueious]

I got dhd.ko compiled and working with netfilter/iptables, but wifi tether freezes the S7 immediately. Droidwall is confirmed to work though, so at least we have that much working.

Anyways we can do more with the kernel now...

Do not have working git, but for now I just used https://github.com/cleaton/liquid-chocolate/tree/master/drivers/net/wireless/bcm4329 and replaced it with Huawei's files

I also coded in the nvram and firmware paths.

 

[pvella]

Sounds like we are getting closer. Great work.

 

[xaueious]

I want someone to clean this up. Just because this works, does not mean this is without bugs. This was a lot of copy pasting and not a whole lot of thinking.

Drop this into the kernel source tree at:

/drivers/net/wireless/bcm4329

Download Multiupload

modify

/drivers/net/wireless/Kconfig

and add:

source "drivers/net/wireless/bcm4329/Kconfig"

modify

/drivers/net/wireless/Makefile

and add:

obj-$(CONFIG_BCM4329)  += bcm4329/

then do a: make oldconfig, and build for BCM4329


Credits:
roggin's modifications to Liquid from Qualcomm Liquid Chocolate (git https://github.com/cleaton) to port BCM4329
Kconfig from cm-kernel, modification to dhd_common.c under dhd_common_int (hardcode firmware and nvram path):

#ifdef CONFIG_BCM4329_FW_PATH
	strncpy(fw_path, CONFIG_BCM4329_FW_PATH, MOD_PARAM_PATHLEN-1);
#else
	fw_path[0] = '\0';
#endif
#ifdef CONFIG_BCM4329_NVRAM_PATH
	strncpy(nv_path, CONFIG_BCM4329_NVRAM_PATH, MOD_PARAM_PATHLEN-1);
#else
	nv_path[0] = '\0';
#endif

I don't know a whole lot about droidwall or iptables but great work!
