So, I love the performance and battery life with this kernel and PureNexus.

However, every time I play a video I get a freeze and reboot. YouTube and browsers both crash.

I want it to work soon bad!

No logs no fun.

We can't replicate on stock ROM sorry.

Flashed this kernel for the first time earlier today and man I'm pretty impressed! Phone is running super smooth and as cool as a cucumber! Played Asphalt 8 for about 30 minutes and the phone barley got warm!
Nicely done!

FYI, i noticed some decent battery drain using r45 with cataclysm, tried fresh install if cataclysm and r45 still drain. Back to r41 and no drain. Not sure what's different but specifically screen off seems worse on r45. I used default settings for cpu/ GPU main adjustments i make is turn on dtw and lower vibration.

There's nothing merged that would justify that.
Need more info.

Yeah I'm no dev but I didn't see anything in battery stats or wake locks showing a cause. I just noticed screen off and over night battery drain and didn't see any culprit on in better battery stats, just didn't seem to be dozing very well. Going back to R41 fixed it.

BTW your kernel is awesome and greatly appreciate the work. R41 is still flawless for me.

Not sure what kind of info/logs i can give you to help but if you want it let me know what I can do. Maybe just anomaly on mine if no one else has similar.

If you see nothing...

Only thing I can think of is the LMK doing too much background work, we'll check it out thanks.

Just go to twrp recovery then go to wipe you will see format data. That will put you unencrypted but make sure you backup your files because everything will be wiped.

Thanks for this work. If we use only 2 cores in the kernel, it doesn't affect fast charge ? And there are no risks for my N6? Thanks in advance for answers.

So you know: blu_spark is compatible with new root method by Chainfire.
http://www.xda-developers.com/chainfire-releases-root-for-android-6-0-without-modifying-system/

Just follow the instructions if you want to test it:
1. flash clean system.img,
2. flash that "systemless" boot.img provided by Chainfire
3. flash blu_spark zip
4. flash zip SuperSU v2.56

Keep in mind this is for stock ROM and this is not a SuperSU troubleshoot thread.
Any doubts or issues related to SuperSU post at correct thread.

So for custom roms we could just flash like it was before on lollipop?

Kernel auditor seems to be experiencing issues with applying on boot. Every time I reboot and kernel auditor applies settings, the phone freezes and soft reboots. Anyone else having this issue?

Sent using XDA One

That could mean that something you're applying on boot is causing the reboot usual causes are undervolting, overclocking, and I've personally had an issue with the "simple_ondemand" gpu governor not on this kernel but on the stock one.

Also not clearing the app data on kernel adiutor when changing kernels could cause it as well

Thanks for explaining

Could you merge the systemless boot modifications in your kernel so we don't need to flash two boots but just your kernel + supersu? :)

    Kernel features:
    • Powered by Ubuntu 14.04.3 x86_64 (sparky VPS @ www.servercore.com.br - thanks @ChristianLetti)
    • Build with toolchain SaberMod eabi-4.9-09272015 cortex-a15 targeted
    • Full -O3 & graphite support with device and target flags enhanced, linaro build improvements, etc
    • Less is more: stockish builds based on android-msm-shamu-3.10-marshmallow
    • Kernel compressed with LZ4-r131, custom tweaked RAMdisk with GZIP (faster boot times, removed force encryption)
    • Removed some debug and logging options
    • Enhanced performance and battery patches
    • Several CPU Governors (blu_active own governor is default)
    • Voltage Control UV_mV_table
    • Enhanced TCP methods (westwood is default), Network and Wifi tweaks
    • Several I/O control (FIOPS is default), tweaked filesystems (F2FS, ExFAT, NTFS & CIFS available)
    • Disabled stock mpdecision and thermald, removed artificial throttles (core hotplug, frequency and battery)
    • blu_plug: Dynamic hotplug for shamu, with screenoff battery saving (max dual core @ max_freq 1190400)
    • msm_thermal simple driver (default 65º C threshold)
    • Optimized RWSEM, AES and SHA1 routines (with neon support)
    • Vibrator Strength tunable (75 level ~ 60 % default)
    • KGSL fixes and reworked GPU driver (removed doubled freqs, goes to idle @ 27MHz)
    • KCAL - Advanced color control for Qualcomm MDSS v3 (RGB calibration and post-processing features)
    • USB Fast Charge (USB mode up to 900mA with MTP mode on)
    • Kexec (multirom) full support
    • Disabled voltage, hotplug, frequency and temperature synthetic mitigations
    • USB automount (ROM must support it, otherwise use stickmount)
    • CDROM emulation added to mass_storage (full Drive Droid compatible)
    • init.d support (busybox run-parts required), Kernel cleaner script
    • Compatible with Kernel Adiutor, Universal Kernel Manage and others

    DOWNLOAD KERNEL ZIP


    Warning: If you come from other kernel, you should dirty flash your ROM before flashing blu_spark zip to avoid problems.
    Reflash ROM -> flash SuperSU -> Boot device and install busybox -> flash blu_spark.
    Also uninstall or clean data of any kernel control app you're using.

    Root is now available in Marshmallow 6.0 in enforced mode thanks to chainfire.
    In stock (or stock derived) ROMs follow the steps bellow. In pre rooted custom ROMs you should only need to flash blu_spark zip
    1. Just go to SuperSU thread and download the kernel zip http://forum.xda-developers.com/apps/supersu/wip-android-6-0-marshmellow-t3219344
    2. Extract the boot.img (not a flashable zip)
    3. Go to recovery, flash boot.img, flash SuperSU v2.50+, flash blu_spark
    4. Profit

    Special thanks to @DariosF and @ciprianruse88, for the friendship, initial push, knowledge and webart.

    blu_spark r26

    All right crew!

    New build is up, latest M3 stuff merged, some cleanup, etc.
    Seems like Google merged some power patches to deal with bug on battery measurement Solid on M, 5.1.1 needs testing.
    EDIT: just pushed r26 quickfix, seems like even with newest Smart Battery and Aging Detection commits, the gauge meter is still derped on M3 source.

    Wicked!
