[KERNEL]Lightning kernel for stock roms

[langeveld024]

Does anyone have the same problem with me? I can't use any app to control the cpu settings and the phone still has turned on screen although i selected to turn off my phone. I flashed .292 boot.img, intelliplug.zip and overclock file. Did i do something wrong?

Yes.
1. Disable mpdecision if u wanna control CPU clocks (by any way u prefer, google it or go to system/bin/ and rename "mpdecision" to "mpdecision.old" and reboot)
2. Turn off double tap to wake and sweep to wake

@nikhil18
Thanks for init.d bro.
99lightning is some nice piece of script, great!
Run's smoothly just as version 1.
I think the best setup is the default setup!

I came from XZ-v26 Kernel after flashing Version 2 of Lightning Kernel my Wifi is not able to connect to a network. It find all networks, but if I try to connect nothing happen. Can someone help me ?

Hi, @nikhil18. After flashing the version 2 I found that the frequency doesn't stick anymore even if I flashed the overclock.zip. I usually underclocked it to 1350 mhz with minimum frequency of 270mhz but it keeps jumping back to the default 384mhz and 1512mhz. I wonder if anyone has this issue too.

Edit1: For some reason, it is fine now.....

Edit2: After leaving the phone there for half an hour, found the issue to be back again....

Edit3: To make sure whether it is my problem, I flashed version 1 back and left it for half an hour, until now it is still fine.

Sorry bro I added a new feature called MSM Limiter by which you change governors,frequency for each core I will updload a modified 99lightning script by which you can control this feature

Thanks bro, I appreciate your work.

 

[nikhil18]

ok guys reuploaded version 2 with modified 99lightning script to control msmlimiter
you have to modify these lines according to your needs

# MSM Limiter disabled by default, 384000/1512000 already coded in driver as default
echo 1 > /sys/kernel/msm_limiter/limiter_enabled
echo 384000 > /sys/kernel/msm_limiter/suspend_min_freq_0
echo 384000 > /sys/kernel/msm_limiter/suspend_min_freq_1
echo 384000 > /sys/kernel/msm_limiter/suspend_min_freq_2
echo 384000 > /sys/kernel/msm_limiter/suspend_min_freq_3
echo 810000 > /sys/kernel/msm_limiter/suspend_max_freq
echo HYPER > /sys/kernel/msm_limiter/scaling_governor_0
echo HYPER > /sys/kernel/msm_limiter/scaling_governor_1
echo HYPER > /sys/kernel/msm_limiter/scaling_governor_2
echo HYPER > /sys/kernel/msm_limiter/scaling_governor_3
echo 1512000 > /sys/kernel/msm_limiter/resume_max_freq_0
echo 1512000 > /sys/kernel/msm_limiter/resume_max_freq_1
echo 1512000 > /sys/kernel/msm_limiter/resume_max_freq_2
echo 1512000 > /sys/kernel/msm_limiter/resume_max_freq_3
# Amount of time in seconds to suspend after screen off
echo 10 > /sys/kernel/msm_limiter/suspend_defer_time
# Set to 1 for debug prints
echo 1 > /sys/module/msm_limiter/parameters/debug_mask

note-1 is to enable and 0 is to disable any feature in the kernel like hotplug,msmlimiter etc

Hi everyone, i have brief question. Why i cant underclock it?

Can you check if your WiFi MAC address has changed? It seems to be an issue for some people around here(including me), but I dont think there's a solution for that other than using another kernel(hodorkernel has problems with mac for me as well).

Did you even look at the posts above you? Goshhh

I disabled the msm limiter and now the frequency sticks since Im too lazy to adjust the value one by one in msm limiter.

Are u using latest version? I do not have any underclock issue.. Underclocked to min 270 Max 1350 and it sticks as it should.
Although I have renamed mpdecision to mpdecision.old in system/bin/ so u could try that and see if it work's

Yes I have this also, but for me it's not a problem. Love this kernel

Oh, ok. For me, it's a big problem, because I cant connect to wifi at work - security. Would love to use this kernel, but cant. Bad luck, I guess.

try this to get your original mac

su
mac-update
mv /system/etc/firmware/wlan/prima/WCNSS_qcom_wlan_nv.bin /system/etc/firmware/wlan/prima/WCNSS_qcom_wlan_nv.bin.old

cp /data/misc/wifi/prima/WCNSS_qcom_wlan_nv.bin /system/etc/firmware/wlan/prima/WCNSS_qcom_wlan_nv.bin

You should try this if you have already connected to wifi on stock kernel

Hmm okay, maybe u can try replacing the WiFi module's from a kernel with know correct Mac address?

(Modules flashed with this kernel are: system/lib/modules/wlan.ko and system/etc/firmware/wlan/prima/wcnss_cfg.dat + wcnss_qcom_wlan_nv.bin)

I don't know but at least u can backup and give it a try

Thank you for your suggestion, but I've already tried that - I don-t have "/data/misc/wifi/prima" directory.

langeveld024, thanks, I'll try it when I get back home.

Don't try to replace modules or this file wcnss_cfg.dat but you can try the above method manually which involves this file wcnss_qcom_wlan_nv.bin because some users in zl forum said that it works

Thank you for your suggestion, but I've already tried that - I don-t have "/data/misc/wifi/prima" directory.

See if you find this directory on stock when you have connected to wifi network or final method is not to flash this file wcnss_qcom_wlan_nv.bin just delete it from kernel zip before flashing

I did before, but I don't have the /prima/ folder in /data/misc/wifi/.
I only have /sockets/ and /wpa_supplicant/ folder's there and a few file's.

Do not replace them, as nikhil18 said. Better reflash stock ,connect to WiFi and do as nikhil18 said.
Backup the file or delete the file from zip :thumbup:

@nikhil18
BTW could u perhaps add simple GPU governor? Sometimes having unresponsive touchscreen when trying to unlock but I never experienced that when using simple GPU gov.

Any one else facing this error and you can try ondemand or try turning of msm limiter

 

[langeveld024]

Yeah it's a known issue on kernel's with dt2w and s2w (no matter if turned on or off).
Will do thanks, I'll check if happens with ondemand

Hmmm.... are you having a glass screen protector or something like that because mine works normal on the default gpu governor which is interactive with dt2w on but s2w off.
