AW: [KERNEL][UV][Linux 3.4.32] Harsh Kernel build Feb-20 - JB 4.2.2

Is there a Difference in battery life between 4.2.2. Stock and harsh?

I've not tried the stock kernel for a long period only a day but always been on Harsh's kernel and battery for me is excellent. Can get through a day with decent percentage left at the end of it with Google Now and some other things syncing and on 3G.

Best thing with this kernel it's just as smooth as stock but battery for me is good.

i was checking out visceralpshyche's v2 profile and liked it. but i increased blue by 5, who wants to give it a try? :D

Looks good, can't tell which I like better but thanks for sharing. I'll run with this for a while :)

Great kernel so far! Only weird thing is that I cannot seem to get faux display to work for colors. Is anyone else having this issues? No matter that I set the setting for they reset to original after I turn screen off and on. Any suggestions to get these to stick would be greatly appreciated!

Recently, I've experienced a lot of wakelocks... sns_periodic_wakelock might fave been caused by an app, but it never occurred before I flashed the Feb 20 kernel.

Harsh,
Does the stock kernel have all the wakelock fixes implemented? Love both your normal kernel and your"stock"one too.

Stock one don't have wakelock fixes, as many here pointed out that wakelock fixes introduced notification delay when on WiFi.

I keep on updating sources, but dont build kernel for release until all if final.
I do build some testing builds for me to run from those sources, but not update here or upload it.

So build Feb-20 is latest build still. Probably new build tomorrow.

And for all those who can compile on their own, sources are always updated :D

Crossing fingers for the new build :eek:

Re: [KERNEL][UV][Linux 3.4.33] Harsh Kernel build Feb-24 - GPU patches

Running nice and smooth so far.. Also standby battery drain over h+ seems to be next to nothing.. Hoping this isn't too good to be true.. Thanks harsh!

Going to keep praising this kernel, yesterday had about 17 hours, with near 4 hours screen on time, wifi on all day, and 3 hours 20 mins worth of phone calls, and around 100 sms messages sent/received. Also have Google Now on all the time. And still had about 10% left!

Fast, fluid, smooth, battery efficient, and just excellent.

Only thing I do is disabled certain apps on start up using autostarts. Even on 3G I come home with about 70% left after a days work as during working days my usage is minimum.

    Hello guys n gals,

    This is Kernel for Nexus 4 should work on all ROMs if having unmodified RAMDISK. For sources visit my github
    It is CWM flashable zip file. So can be easily flashed.
    Those having kernels with modified RAMDISK and other things, do flash RESET kernel(provided by other great devs in their kernel thread) before flashing this kernel.

    harshkernel was made by me from google sources, and some extra tweaks for Personal USE.
    I do not have time to support like other devs, I am just sharing what I have made for myself as my daily driver.

    Well, our cpu are made at some quality standards. We have 4 different quality of cpu for apq8064 from Qualcomm. so depending on which one is on your phone it selects frequency table from slow, nominal, fast and faster.
    Google kernel source have same frequency table for fast and faster. So those with faster are not getting their extra advantage :crying:
    You can identify you CPU chip by below command in terminal.
    adb shell dmesg | grep PVS
    It will give you some output as given example below
    Code:
    adb shell dmesg | grep PVS
    [ 0.873920] acpuclk-8064 acpuclk-8064: ACPU PVS: FAST
    And faster binned CPU has lot to do with UV, when you look as frequency table of faster, it is already preconfigured to have lower voltages than fast, and lot lower than slow binned.
    Phones with faster binned should have better battery than slower binned phone out of box without any other configuration.
    And for UV its already hardcoded and can be adjusted by System Tuner app further. And OC I am not willing to add. Maybe will adjust frequency(underclock) later on but hardcoded and tested.

    Features:
    • Added support for people who have CPU with FASTER binning.
    • So now cpu supports Slow, Nominal, Fast and Faster.
    • UV accordingly to have best stability. min UV is 100 so also not so less either
    • Updated OnDemand and Interactive governor
    • Raw ioscheduler
    • Gamma control faux, also enabled init.d
    • HSIC wakelock fixed

    If you like it hit THANKS button.

    Download file is in AnyKernel format from koush, should work on all ROMs with unmodified RAMDISK
    harshkrnl build June-10 Linux 3.4.48 Link: DOWNLOAD

    No update to boot.img from now on, cant upload stuff as fast as before. Slow internet :(
    Boot Image Feb-20 (build with new 4.2.2 ramdisk): http://d-h.st/7vB

    Google's 4.2.2 Stock kernel with UV, Gamma and faux's Sound. Nothing more nothing less.
    Download Link: http://d-h.st/8z8

    boot images will not be updated, as having very few downloads :D... maybe those who use it are senior members and can pack by their own if required.

    # Harshkernel default settings

    Values marked in RED color are only values you need to change while using this script.
    and all these echo commands you can use it in terminal too, or you can run script from terminal.

    I am providing scripts here, so you can directly download it to your mobile phone. Remove txt extention, and put it in /system/etc/init.d folder, and set permissions.
