Sorry to be a pain @xanthrax any luck with b47?:confused:
Ohh... Unfortunately I can't find that b47, apparently the clouds we stored these kernels are empty or containing fee versions, I will try to resurrect my dead Nexus 4 to see what I can find inside of his belly, damn I miss that phone :(

No worries just wanted a KK kernel & IMO that particular version was the best, hey-ho thanks anyhow.

@hellsgod I've got an issue with this kernel using chroma and magisk. with b88
Apparently this kernel sets the /sbin/.core/img folders to read only and nothing can change this to RW for magisk to work properly. I've asked this in the magisk thread and it's been decided that this kernel is causing this issue. by setting some things to read only. as when i use chroma's default kernel, no issue like this is present.


This is what should be happening, but it's not.
I dont know if you can offer some advice as this kernel is fantastic for my nexus, Super low core speed, everything.

    please check the 2nd , 3rd and the 4th post for some more info

    Starting with version b40 ( JSS, JWR and CM) the multiboot patch by Tasssadar has been applied so it can be successfully used for.

    Change logs b65 onwards

    -temp threshold set to 70°C
    -few commits from M
    -updated toolchain

    -updated BFQ-reverted gpu patches to fix chrome issues-some little fs fixes-hellsCode from @Maxr1998

    -added back Franco`s input listener-added back Franco`s conservative
    -added input boost logic to hellsactive

    -Reverted back to GCC 4.9.3 and reverted conservative changes, switched back to hellsactive.
    -should be back to the state of b73 now, except updated faux sound, 5.1.1 commits from google and bfq I/O sched.

    -faux sound updated-hopefully screen freeze issue fixed

    (b74) http://forum.xda-developers.com/showpost.php?p=60370527&postcount=10313(b73)-Merged a patch from stratosk to temporarly disable dt2w with the power key.
    -Enable it with "echo 1 > /sys/devices/virtual/input/lge_touch/dt_wake_pwr_disable"
    - If you use your power key to turn off the screen, dt2w will be disabled, until you turn it on with the power button again.

    (b70)-compiled with UBERTC-build flags from shamu/hammerhead(b69)-some fixes from linux upstream (3.4.y)
    -new build flag (floop-nest-optimize)
    -rtmutex fixes-sched/nohz/irq/genirq improvements from linux mainline

    -Upstream changes from Linux upstream (refer to git)
    -Some fixes for hellsactive/interactive-Removed boost framework from msm_mpdecision
    -Added cpu-boost for input boost and thread migrations-Improved cpu-boost-Make scheduler aware of frequency state-writeback fixes-some other little things

    -misc kgsl updates from caf-disabled some debugging and tracing
    -optimizazions for interactive and hellsactive-misc other little fixes for rq_stats and sched

    -Merged latest "L" commits-Merged some upstream stuff from my hh branch

    Change logs - old kernels

    as from b47 to b64 the kernel it is compatible ONLY with android 4.4.3/4/L

    from b65 onwards the kernel works for L only

    (b64)-Several ARM patches for suspend/cacheflush/MPU (little longer wakeup time from time to time - but a little less drain during sleep)-New build flags-kgsl: Wakeup only for touch events (to make sure the input event handler is called only for touch inputs)(b63)-kgsl upstream for using with the new drivers-UIO fixes(b60)reverted slimbus changescompiled with new boostedtcmisc fixes(b58)-smp fixes from upstream-mm, vmscan fixes from upstream-random fixes from upstream-smartmax is back!-memcpy optimizations for cortex A15 (i know we don't have a "real" A15, but lets test it)-lib: Use neon-vfpv(b57)-kthread fixes-sched/nohz fixes-tick fixes-cgroup fixes-slimbus controller from hammerhead-some improvement for the slimbus-msm_mpdecision: a tad more conservative, check-enabled sched_mc and cpupower-set fiops as default scheduler-set sched_mc = 2(b56)-merged some upstream fixes-reverted two cpuidle patches(b55)(b54)-New governor: hellsactive*-speedup late resume (faster wakeup)-ext4 patches-pm/bus patches to prevent reported crashes (feedback needed!)-some other little fixes here and there-compiled with boostedtc 4.9.2 by @aznrice2k4*hellsactive:-Based upon intelliactive-removed input boost (we have an input boost in the hotplug driver)-removed sync feature-removed sampling down factorFollowing was added:-Align timer windows for all CPUs*It's more advantageous to evaluate all CPUs at same time so that interactive governor gets a complete picture of the load on each CPU at a specific time. It could also reduce number of speed changes made if there are many CPUs controlled by same policy. In addition, waking up all CPUs at same time would allow the cluster to go into a deeper sleep state when it's idle.-Reset last evaluated jiffy in idle callback*When CPU has been busy for a long time, last evaluated jiffy will be quite behind because the timer would have been canceled. We don't want to schedule a timer to fire in the past as load will always be 100%. Reset last evaluated jiffy so that timer will be scheduled for thenext window.-Round up timer_rate to match jiffy*Timers are scheduled in unit of jiffies. Round up timer_rate so that it matches the actual sampling period.-Use del_timer/add_timer_on to rearm timers*Replace mod_timer_pinned() with del_timer(), add_timer_on(). mod_timer_pinned() always adds timer onto current CPU. Interactive governor expects each CPU's timers to be running on the same CPU. If cpufreq_interactive_timer_resched() is called from another CPU, the timer will be armed on the wrong CPU.Replacing mod_timer_pinned() with del_timer() and add_timer_on() guarantees timers are still run on the right CPU even if another CPU reschedules the timer. This would provide more flexibility for future changes.-Support variable frequency calculations**Use a threshold value up to which we are evaluating the current speed weighted by current load against each new choice of speed. Above switch to the original frequency calculation proportional to load relative to the max possible frequency which allows for more dynamic and fair changes.Default threshold is policy->min which guarantees minimal freqs and energy usage during (offloaded) media playback.Also, choose the highest frequency below or at target, which generally saves us one freq level.-Don't scale beyond min if the load is low***-Thread migration commit***http://forum.xda-developers.com/showpost.php?p=55298804&postcount=7952I've just made some little changes on commits to suit my needs.credits:*CAF**myfluxi***franciscofranco(b53)-fixed cores getting stuck at input_boost if you've min 2 cores online: commit-updated msm_mpdecision with latest nexus 5 commits(b52)Compiled with Linaro 4.9.2-2014.08 by Christopher83New build flags from my hammerhead branch and @baromeCode is identical with b51.

    Q&A Game

    Q: My kernel app tells me my min_freq is 918mhz. Why is that?
    A: Its because of input boost. Your frequency will be boosted to 918mhz as soon as you touch your screen. It will be boosted for 1 second after touch. So you have smooth animations and no scrolling stutters.

    Q: My device rebooted / didn woke up from deep sleep. What can I do to help you to find the cause?
    A: Install "Syslog" from the Play Store and get me the "Last Kernel Log" or do it via terminal. You'll find the command one post under this.

    Q: Will you add S2W/S2S again?
    A: No. We're using dt2w from starosk now. If you want to use S2W with my kernel, clone my sources and add it by yourself.

    Q: Why the cpu jumps to 1134mhz so ofter during idle?
    A: Thats because we're using an interactive based governor. Interactive based governors jumps to hispeed_freq (1134mhz) if the load reaches 99%. Don't forget, even if you're doing nothing, you always have some background load. The lower you set your min_frequency, the faster it reaches 99% load and will jump to hispeed_freq more often.

    Battery Profile:

    I've made a battery profile for hot plug settings. Following is changed:

    echo "20" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_0 = Threshold for cpu1 to kick in
    echo "85" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_2 = Threshold for cpu2 to kick in
    echo "10" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_3 = Threshold for cpu1 to kick out
    echo "99" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_4 = Threshold for cpu3 to kick in
    echo "45" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_5 = Threshold for cpu2 to kick out
    echo "60" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_7 = Threshold for cpu3 to kick out

    Most of the time you'll be running on dualcore mode (cpu0 and cpu1). If the load reaches a high level with both cores maxed out, the other cores kicks in and will go off again really quickly. The profile will be active after 90 seconds (counted from bootanimation) so your device boots up with full power first. It'll be stupid to limit it on bootup.

    Balanced Profile:

    echo "15" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_0
    echo "35" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_2
    echo "8" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_3
    echo "55" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_4
    echo "20" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_5
    echo "40" > /sys/kernel/msm_mpdecision/conf/nwns_threshold_7

    Its a little less conservative than the battery profile and a little less aggressive than the default values. I've tried to make something in between. Try it and left a comment :)
    Finally after some days with my N5 kernel I've found time to compile a new kernel for our beloved N4 :) I've called it b44, because it should be the final b44. It was long enough in a test stadium... One thing I still have to do, is hardcode 192mhz as min freq, because some device won't boot, even if 192mhz is defined as min freq in the script. But the script will be executed some seconds later, so the device will spend very short time on 81mhz.

    The kernel isn't public yet on dev-host. I've just added some things, compiled and it booted fine. Flash only if you know what you're doing!




    -Linaro 02.2014
    -Linux 3.4.82
    -Kernel Mode NEON
    -futex Changes from upstream (faux123)
    -Some other things (=

    I,ve played around with the N4 in the last few days and I don't see the need to add new governors atm (like intelliactive). intellidemand does exactly what I want it to do. I don't want to add a new governor, only because its around there.

    Feedback is welcome, as always :) If I've forgot something to add I said I'll add in this one, please let me know :)

    Aaaand good night (it's 05:46 AM here...)

    I will post here the most common issues , if any and a collection of tricks and tips based on all users experience , then will be easier for everyone to track them ;)
    i will keep an eye on every post :cowboy:
    Please have a look first at this thread
    [Repository] [MakoStuff] [Nexus4 Tools] by @gorilla p

    then >>> Troubleshooting Synapse

    also >>> Installing Synapse and importing profiles

    as from version b49 the kernel has been completely rebased therefore I will add below some new tips and tricks

    - first check the change log from b49 onwards and also the discussion starts with that post

    - the kernel isn`t undervolted anymore by default so , heating occurs due to stock voltages , I`m sure you know what to do then

    - new dt2w by stratosk dropping the s2w/s2s feature

    - some inputs here http://forum.xda-developers.com/showpost.php?p=55232079&postcount=7836
    terminal command for dt2w
    echo 1 > /sys/devices/virtual/input/lge_touch/dt_wake_enabled
    thanks @steviemch for heads up

    - try this http://forum.xda-developers.com/showpost.php?p=55214263&postcount=7820 if you`re facing in call delay , thanks @eurochild
    - fsync status
    For those who wants to use the latest hellscore based on KK 4.4.2 on a ROM based on 4.4.3/4/L , here is a fix for loosing WIFI

    Hells-Core kernel with OTG support for Nexus 4 KK
    thanks @justvarshney

    as some other kernels comes with their own ramdisk which will remain over after flashing hellsCore and an unpredictable negative impact on your phone stability may occur , i would recommend you to flash a STOCK KERNEL from below prior flashing

    Nexus 4 Stock 4.4.3 KTU84L >>> http://d-h.st/qxB

    Nexus 4 Stock 4.4.2 KOT49H >>> http://d-h.st/W8P

    Nexus 4 Stock 4.4 KRT16S >>> http://d-h.st/HwN

    Nexus 4 Stock 4.4 >>> http://d-h.st/apv

    Nexus 4 Stock 4.3 >>> http://d-h.st/TRC

    Nexus 4 AOSP 4.3 >>> http://d-h.st/NuC
    the recommended applications to control/modify the kernel are
    Trickster MOD Kernel Settings
    Faux123 Kernel Enhancement

    to be used only for 4.3/1 kernels
    doesn`t affect kk kernels , in case of a broken wifi , just re-dirty-flash your rom and then the kk kernel

    please provide logs in case of troubles
    use the command below in terminal emulator to extract the last_kmsg in case of a sudden reboot

    cat /proc/last_kmsg > /sdcard/last_kmsg.txt

    A nice collection of terminal commands to manually modify the kernel settings as per your desire made by @shengovind
    thanks pal ! ... i must write a song for him now ... oh well
    To Set CPU Governor:

    echo "NAME" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
    echo "NAME" > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
    echo "NAME" > /sys/devices/system/cpu/cpu2/cpufreq/scaling_governor
    echo "NAME" > /sys/devices/system/cpu/cpu3/cpufreq/scaling_governor

    NAME can be replaced by intellidemand, interactive, conservative, wheatley, ondemand, performance
    Default is intellidemand. Changing NAME to conservative changes CPU governor to conservative


    First set governor then you will be able to edit these..
    I do not know what each and every parameter does so these won’t help normal users’ and those who know what these mean will probably know how to edit these. But I’ve included them just because i had to …
