Hi noquierouser,

Have you tried the S7562 kernel yet ? Does it fix Bluetooth or not ?

It cant fix bluetooth because the rom also needs heavy modification to make it work.

Nevertheless you should try the kernel.

There is some usability improvement over the kernel that ships with your cm11 rom.

-otg support
-safe OC boots with 1008MHz then OC from performance menu
-frequencies chosen in performance menu now stick because of disabled sec_dvfs
-OC steps 1152 - 1228 - 1305
-and more minor things

The base is same as --> BA2X_2.0 by @Codename13 and @jonypx09

as the kernel is patched for working bluetooth depending on a patched cm11 rom there might occur errors on S7560 devices without modified rom.
Would be cool if you try it and report back.

Thanks

I'm sorry I did not understand correctly.

I'm specifically looking for a Bluetooth fix, as the phone is not mine, and I can't promise to be able to test other features. The sticky frequencies in performance menu look great though, I hope they can improve the battery life.

As i mentioned some posts earlier the developer of the rom or someone else needs to modify the kernel and the rom according to this guide.
The developer of the s7562 cm11 rom m4jonez has already done the hard work and partially uploaded to github.
The rest can be picked from my github.
For an experienced person it is rather easy to do this for s7560(m) too.

The rom needs to be rebuild there is no other way.

Dont expect any improvements regarding battery-life.

Thank you for that information.

Indeed, the guide seem awesomely detailled. I have however no experience in Android/ROM development (I mostly do bug report, and am trying to update apps on f-droid.org)…


Why is there no improvement to expect ?
IIRC, the min frequency does not stick, and resets to max frequency, so I would think it generates a lot of useless power drain.

If min frequency now sticks, the CPU can slow down when not in use, hence saving power… or not ?

Wait are you using performance governor?
Then your explanation would make sense. In this case thats no bug because the performance governor holds the max frequency all the time.
So changing from performance to any other governor would propably result in saving power.

What i meant is that the max frequency is no longer overriden by "sec_dvfs" and sticks according to what you set it.

"sec_dvfs" is a feature by samsung that dynamically sets voltage and frequency according to some variables in theory.
I heard of samsung using it to betray when running benchmarks on a device(idk if thats true but possible).
There is no documentation about it. But i think it is dependent on proper framework integration what cm11 just does not support.
In addition i wasnt able to find any custom kernel/rom using this so i disabled it.

As a sideeffect the max frequency stays at what you set it.
There is no problem i know with the min frequency.

I actually don't have the phone near me, so I can only try to remember. But since I'm no fan of the Performance governor (too much drain), I can't see why I would have set it up.

Anyway, I'll chek and get back if needed. Thanks a lot !
