[KERNEL] [blu_spark r152] [Marshmallow 6.0.1 / Nougat 7.1.*]

There are no major modifications (none, actually) related to the kernel in the last factory image. I didn't even boot once with the stock kernel. I flashed stock and system images, booted into recovery, flashed blu_spark, cleared Cache and Dalvik-Cache and I booted into it. We are also Stagefright free, I tested with the app from the researchers that discovered the Stagefright bug.

Hi i dont have my rom, i only have my delta update for cataclysm thats why i cant dirty flash. Is there any way i can flash blu spark without dirty flashing?

Try clean flashing

Please Check you PM.

I don't reply to development questions by PM.
And I already replied about the question awhile ago in this thread, N4 has a different panel from N5, so not gonna happen.

How to clean flash?

This means: you wipe your phone clean (from recovery), then install your Cataclysm, Gapps and finally the kernel.

Has anyone used this for dirty unicorns?

Does anyone here use Xmod with COC with this kernel?? Because its not working for me with bluespark, hellscore kernels. But working with elementalx, uber kernels.!! I know the answer am gonna get is its not kernel related. But i wanna know whether anyone got this problem with this kernel. ? ✌

xmod is working well here bro check your rom

I got it working by moving it to system. Otherwise it wont work with any latest rom for me?✌

No, it's not franco version. Mine has a couple upstream patches and that's about it.
I only work in blu_active which is my choice above anything else.

@eng.stk,

#1. The version of conservative you have included is awesome, I like that sampling_rate can be changed (unlike tons of other kernels that have it hardcoded at 200000), and that freq_step and freq_down_step are separate tunables too. If you could keep it updated with upstream that'd be really cool.

#2. Could you do the same for the interactive governor as well? Just keep up to date with upstream patches? Currently the above_hispeed_delay tunable for interactive cannot be modified, which makes it somewhat less useful than it could be.

#3. For blu_active, what does the low_load_down_threshold tunable do? Also, is there a way to modify the duration of input_boost_freq, or disable it entirely?

#4. I think I'm a fan of what you've done with blu_active. It really behaves like a cross between interactive and ondemand, unlike a lot of other custom governors for the N5 which seem to act a lot more like ondemand and favor the max frequency way too much for my liking. Right now I'm using blu_active for a performance-biased governor, conservative for balanced, and hopefully interactive for battery, if you can update it.

For #3, use boostpulse_duration. That controls the length of the input_boost

@eng.stk hey bro, need your help. Is there anyway i could improve performance of the kernel. Using blue_active governer, and under heavy usage i feel a lot lag here and there when using multiple apps. I even changed thermal throttling temp to 90°C. But still i have lag. It happens only when heavy multitasking like fb, coc, whatsapp, hike, google+ etc....? ✌

Have you tried clearly dalvik and cache?

Try to change blu_active settings like on the screenshot

I had the same problem, I changed the hispeed freq,input freq, high speed load in kernel adiutor, but underclocked to 1.7ghz,basically changed the settings to make it easier to reach a higher frequency without generating more heat.

I had lag when the cores were parked and frequency was low, when I multi tasked or pressed the home button there would be a long delay and lag when in the app draw,

low_load_down_threshold is a threshold in which under it , cpu doesn't scale: let's say it's 10, if load is under 10% cpu freq will not scale. Improves low freq jitter.
you can change the input boost duration chaqnging boostpulse_duration. You can disable input boost making input_boost_freq to 300000
