[KERNEL]lightning kernel cm11

[nikhil18]

Lightning kernel

this kernel is made for cyanogenmod 11 roms and i take no responsibility if you brick,destroy your device due to this kernel

features
sound control 3.2
gpu overclock to 627mhz
intelli thermal
cpu overclock upto 1836mhz(disable mpdecision)
compiled with linaro 4.9.1
added intelliactive,intellidemand,preservative,hyper,wheatley,lionheart governors
row,fiops,tripndroid io schedulers
undervolting
sweep to wake and double tap to wake
auto mpdecision (turn off stock qcom mpdecession)
sound stuttering fixed(zzz sound while hearing music)
Motorola MSM memcpy enhancements
cpu unallingnment access
kernel mode neon
exfat support
gpu voltage control
more to come

Setting custom GPU Voltages via sysfs

NB:
- Safe lock is present on MIN/MAX values:

Quote:
#define GPU_MIN_VDD 900000
#define GPU_MAX_VDD 1200000
The default GPU voltages are:
Quote:
+ [VDD_DIG_NONE] = 0,
+ [VDD_DIG_LOW] = 975000,
+ [VDD_DIG_NOMINAL] = 1075000,
+ [VDD_DIG_HIGH] = 1175000
Verify the actual settings:
Quote:
cat /sys/devices/system/cpu/cpu0/cpufreq/gpu_mv_table

975000
1075000
1175000


Adjust to desired values and verify:

Quote:
echo "930000 1000000 1100000" > /sys/devices/system/cpu/cpu0/cpufreq/gpu_mv_table

Will test it

WiFi isn't working for me, can't turn it on

WIFI isnot work

 

[nostupidthing]

i just want my 2nd mic to work in custom rom, does this help?

 

[merhans]

Test it and give feedback, if it doesn't help, flash the normal cm kernel or boot.img

Sorry, is there any special instructions for installing this kernel, or just flashing it? I want give it a try.

 

[nikhil18]

guys is doubletap2wake and sweep2wake working for anyone

Not for me. I tried your kernel with CM11 nightly last night and sadly, d2wake is not working

 

[Thibou]

On Carbon(CM11 based) doubletap2wake doesn't works with default kernel and still not working with Lightning kernel.

But anyway, thanks for your work @nikhil18 :good:

 

[EnzoDC]

Thanks @nikhil18! This solved my sound stuttering bug

Could you explain to me what the intellidemand etc. intelli stuff governors are for? I never understood what they were for :$ All I know is that ondemand and interactive is a good governor and is not a battery hog unlike Performance.

EDIT [ADD ON]: I would like to thank you for this Kernel, my ROM is smoother than before and more consistent in terms of performance, even though it already is, I can feel that it is, and its not placebo.. Keep it up. Looks like Im gonna have to set up my 2nd bank account with paypal and start donating for awesome devs like you haha

 

[kostazol]

it doesn't work with mokee rom.

 

[nikhil18]

it doesn't work with mokee rom.

then the sources are different sorry cant do anything about it

 

[kostazol]

then the sources are different sorry cant do anything about it

it work but with errors, after starting i have error systemUI. Can you repair it?
P.s. I install your kernel without wipe.

bro mooke rom uses a different sourcecode and its not based on cm11 and i need to make a kernel from scratch to support the rom

 

[kostazol]

del

 

[nikhil18]

Thank you for answer, I thought that mokee is cm11 based rom. I will be very happy if you make your kernel for mokee, but i understand that it is difficult and it needs your time.

Kernel works great

Kernel has been working smoothly for me on Carbon Rom. I don't have Bluetooth audio stuttering anymore but I do still get sound stuttering (bluetooth as well as through phone speaker) in Plants vs Zombies 2. This stuttering also occurred in the stock kernel so it might be an app optimisation problem. I've tried other governors and it doesn't seem to make a difference.

Thanks for the kernel mate.

About v7 on my ZR (CM11) :
- Impossible to undervolt (no tab on SetCPU)
- Very instable when overclocking. Phone freeze and reboot just after set max frequency.
