BLN Support for SGS2 - With Example.

[samaral]

Hi Dev's

This is not my code, so credits to the owner 'creams'
I happened to stumble on some code yesterday from somebody who have attempted to integrate BLN to his kernel and done it successfully.


I thought the dev's might like to take a look at this one and implement this on their work.


blog : http://creamsnexus.blogspot.com/
git : git://github.com/creams/SGS2-SC02C-BLN-Kernel.git

His kernel was built for the Jap version of GS2.

Cheers!

AdamG has already implemented this into his AOSP ROM and it's working fantasticly, I know another Dev has already implemented it into a ROM just forgot his name. Thanks for pointing us to the source though!

 

[samaral]

hope that the devs give credit to the fix/implementation.

Ninpo also has putted it into his GIT so maybe they are already aware of it

 

[samaral]

oh i gave him a pm about it before i posted this.

July 31 in his GIT. You're ahead of him maybe.

I hope we will get it on MIUI and CM7 as well

Don't know about MIUI but for sure on CM7. It's probably low on their to do list but BLN is something they will most definitely support just as they did with the 2X/G2X

im from the past

i didnt check his git commit date. thanks for the correction.

Do i also need to install any app from the market to enable it ?

Answer : Yes

Sorry if this is a noob question but what is BLN?

Back Light Notification

using the led keys for notification.

Yay, my kernel will have BLN support to in the next version, just need to build all the seperate versions

(time to make a "one-for-all" kernel, that goes onto any (stock) ROM.... )

the only downside to this bln "version" is that it uses a kernel wakelock that will be hard on the battery

Yep, people are in for a treat when they realize their battery is being raped. We'll have to wait for CM7 to implement it into the framework like they did with the Optimus 2X/G2X

Nothing can beat the old good trackball lights on N1
It's a pitty all the brands stopped producing trackball,they could just reduce its size

Yeah.... that is.... so not nice.... but well.... can't have everything.... :-/

// EDIT
Hm, for one, maybe some things can still be tweaked in the involved kernel code and for the other, how about disabling BLN when not needed? Does that release the wakelock? Haven't checked yet.... should check....

And does the drain/wakelock accour all the time while while activated or only when the lights are actually on - as far as I understood it so far the wakelock ist required to keep the powersupply up for the lights, but when no blinking is needed (due to no notification) the wakelock could/should be released....

Maybe that's something to tweak if that isn't already the case.
If the drain only accours when the lights are on, that's kinda OKish IMO, time to answer the damn phone *lol*

 

[ogdobber]

so creams put out an update that is supposed to release wakelock after the led cycle (pro app needed)
That would be an acceptable solution, I am testing to see

ps, btw jlevy he wasn't keen to your battery rape comment

It wasn't anything personally directed at him. I'm very grateful for his work in bringing BLN to our devices. I appreciate the update it looks like it will have a helpful impact on battery life.
