Changelog & Tunables

Changelog:
Commit History

My kernel now deletes /system/bin/mpdecision and /system/bin/thermald which are not needed and interfere with my kernel and automatically removes older busybox, installs latest busybox as well as runs a cleaning script to reset Synapse, FauxClock & Others to make sure the kernel boots up properly without bad settings. FauxClock & Synapse do have a profile saving feature, use that before flashing.

Older Kernel Builds Here

Alucard, Darkness & Nightmare CPU Freq Tunables:

inc_cpu_load_at_min_freq:
This threshold is used as up threshold while sampling at frequencies less than freq_for_responsiveness. Above that, normal inc_cpu_load is used. This gives us an option to make scaling aggressive/relaxed until a frequency and normal for higher frequencies. (Only for Nightmare, Alucard). (Default: 60%)"

inc_cpu_load:
The frequency at which governor scales CPU up. Load big or equal inc_cpu_load: cpu scaled up. (Only for Nightmare, Alucard). (Default: 70%)

dec_cpu_load_at_min_freq:
This threshold is used as down threshold while sampling at frequencies less than freq_responsiveness. Above that, normal dec_cpu_load is used. This gives us an option to make scaling aggressive/relaxed until a frequency and normal for higher frequencies. (Only for Alucard). (Default: 60%)

dec_cpu_load:
The frequency at which governor scales CPU down. Load less than dec_cpu_load: cpu scaled down. (Only for Nightmare, Alucard). (Default: 70%)

When current freq is greater than freq_for_responsiviness_max, freq_step_dec will be equal to freq_step_dec_at_max_freq. (Only for Nightmare).

freq_responsiveness:
Until freq_responsiveness, Up Threshold considered for sampling load is inc_cpu_load_at_min_freq. Also during the part where CPU is at maximum load frequency, governor need to find the optimal frequency as the next frequency - which should not trigger up_threshold in the next sampling. When such a frequency_next is found to be a) less than freq_responsiveness b) will not trigger down_threshold in the next sample, then the optimal frequency is set to freq_responsiveness. (Only for Alucard)

pump_inc_step_at_min_freq_1-4:
Governor should increase CPU0 frequency by n step each time CPU load reaches inc_cpu_load_at_min_freq. (Only for Alucard) (Default: 2)"

pump_inc_step_1-4:
Governor should increase CPU0 frequency by n step each time CPU load reaches inc_cpu_load. (Only for Alucard) (Default: 1)"

pump_dec_step_1-4:
Governor should decrease CPU0 frequency by n step each time CPU load reaches dec_cpu_load default 30%

freq_up_brake_at_min_freq:
Brake scale up frequency when load big or equal inc_cpu_load_at_min_freq. (Only for Nightmare). (Default: 20)"

freq_up_brake:
Brake scale up frequency when load big or equal inc_cpu_load. (Only for Nightmare). (Default: 20)"


freq_step_dec:

Tips/Tricks:
This Works great with Temasek CM11 here
Also was especially designed and optimized for Android L here
Also works with CM11/CAF based ROM's, flash the CM11 kernel.

Other governors have been added so you have full control in tweaking your device:
SmartMax, Wheatley and OndemandPlus are more battery efficient than Intelliactive that is default, to compensate with intelliactive, undervolt

Setting a Higher Hysteresis value for IntelliPlug will help with battery, lowering it will improve performance.

Lowering the Intelliactive Boost cores can save battery.

99% of the Kernel features of this rom can be customized and set automatically on boot via init.d, you don't need Synapse if you are a cmd line pro and want to save a little bit of processor time/battery:

Available CPU Governors Explained:

IntelliActive
Based off Google's Interactive governor with the following enhancements:

1. self-boost capability from input drivers (no need for PowerHAL assist)
2. two phase scheduling (idle/busy phases to prevent from jumping directly to max freq
3. Checks for offline cpus and short circuits some unnecessary checks to improve code execution paths

Intellidemand:
Intellidemand aka Intelligent Ondemand from Faux is yet another governor that's based on ondemand. Unlike what some users believe, this governor is not the replacement for OC Daemon (Having different governors for sleep and awake). The original intellidemand behaves differently according to GPU usage. When GPU is really busy (gaming, maps, benchmarking, etc) intellidemand behaves like ondemand. When GPU is 'idling' (or moderately busy), intellidemand limits max frequency to a step depending on frequencies available in your device/kernel for saving battery. This is called browsing mode. We can see some 'traces' of interactive governor here. Frequency scale-up decision is made based on idling time of CPU. Lower idling time (<20%) causes CPU to scale-up from current frequency. Frequency scale-down happens at steps=5% of max frequency. (This parameter is tunable only in conservative, among the popular governors)
To sum up, this is an intelligent ondemand that enters browsing mode to limit max frequency when GPU is idling, and (exits browsing mode) behaves like ondemand when GPU is busy; to deliver performance for gaming and such. Intellidemand does not jump to highest frequency when screen is off.

Pegasusq

The Pegasus-q is a multi-core based on the Ondemand governor and governor with integrated hot-plugging.
Ongoing processes in the queue, we know that multiple processes can run simultaneously on. These processes are active in an array, which is a field called "Run Queue" queue that is ongoing, with their priority values ​​arranged (priority will be used by the task scheduler, which then decides which process to run next).

To ensure that each process has its fair share of resources, each running for a certain period and will eventually stop and then again placed in the queue until it is your turn again. If a program is terminated, so that others can run the program with the highest priority in the current queue is executed.

Nightmare
A PegasusQ modified, less aggressive and more stable. A good compromise between performance and battery.
In addition to the SoD is a prevention because it usually does not hotplug.

The Hyper (formerly known as kenobi) is an aggressive smart and smooth, optimized for SGS2 getweakt and, based on the Ondemand, which was getweakt of Arighi and was equipped with several features of Ondemandx suspend imoseyon. (Added by sysfs, the settings suspend_freq and suspend Imoseyon's code) is the behavior of the hyper Ondemand if he is in action, very similar. He also has the Arighi's fast_start deep_sleep and detection features. In addition, the maximum frequency is in suspend mode 500Mhz.

SmartMax
Well - you did it it 100% correct :)

Some more info

The basic idea - which comes from smartass - is the concept of an "ideal" frequency.

The following strategy is used:
1) If load is above upper-threshold and current frequency is below ideal freq
-> jump to ideal in one step
2) If load is above upper-threshold and current frequency is at or above ideal freq
->do "ramp up" steps which will include all frequencies for a specific
amount of time - so compared to ondemand no "jumping" to max frequency
3) if load is below lower-threshold and current frequency is below ideal freq
->do "ramp down" steps
4) if load is below lower-threshold and current frequency is above ideal freq
-> jump down to ideal in one step

All those thresholds ramp steps and frequency stepping times are
fully configurable using sysfs. By default I tried to create a good balance.

The ideal frequency for "us" is 475000 which is the maximal frequency
of the LP mode of the tegra chip. This will allow using LP mode as much as possible

Additional to make it "snappy" smartmax has "touch poke"
So input events from the touchscreen will boost the cpu for a specific
time to a specific frequency.

BluActive:
Based of Google, CAF, CM, myfluxi and franciscofranco Interactive by @eng.stk

Wheatley:
Building on the classic 'ondemand' governor is implemented Wheatley governor. The governor has two additional parameters:
target_residency - The minimum average residency in µs which is considered acceptable for a proper efficient usage of the C4 state. Default is 10000 = 10ms.
allowed_misses - The number sampling intervals in a row the average residency is allowed to be lower than target_residency before the governor reduces the frequency. This ensures that the governor is not too aggressive in scaling down the frequency and reduces it just because some background process was temporarily causing a larger number of wakeups. The default is 5.
Wheatley works as planned and does not hinder the proper C4 usage for task where the C4 can be used properly .
For internet browsing the time spend in C4 has increased by 10% points and the average residency has increased by about 1ms. I guess these differences are mostly due to the different browsing behaviour (I spend the last time more multi-tabbing). But at least we can say that Wheatley does not interfere with the proper use of the C4 state during 'light' tasks. For music playback with screen off the time spend in C4 is practically unchanged, however the average residency is reduced from around 30ms to around 18ms, but this is still more than acceptable.
So the results show that Wheatley works as intended and ensures that the C4 state is used whenever the task allows a proper efficient usage of the C4 state. For more demanding tasks which cause a large number of wakeups and prevent the efficient usage of the C4 state, the governor resorts to the next best power saving mechanism and scales down the frequency. So with the new highly-flexible Wheatley governor one can have the best of both worlds.
Obviously, this governor is only available on multi-core devices.

OnDemandPlus:
A governor based off of OnDemand and Interactive. It provides a balance between performance, and saving battery.

i was using 63u before while charging the phone on 63u the cpu temp be around 45 degree but on 64u while charging it goes to 55 to 60 degree don"t know why

edit intelli-thermal throttling lower and edit the Hysteresis value higher, and make sure you undervolt to lower temps as well ;)

Flash the Anykernel version in the future, my version for L removes the charging profile that uses lower frequencies to lower temp while charging.

Alternatively you can use FauxClock and set the charging thermal throttle to a temperature you specify ;)

my hysteresis value is 8 and intellithermal value are default i don"t use undervolt and two error sseekbar failed...i attach the screen shot
but in 63u no heating issue

Shout out to @apb_axel to fix UKM, I'll take a look at what may be causing your higher temps. Thanks for letting me know :)

Your welcome, thankyou guys who are coming from the Android L Bunny stew thread! Let me know if anyone has any feature requests, and I'll look them over and possibly implement them.

The kernel is just awesome! Full of features and reliable.. Not a single issue till now! I used AK when I was on KitKat, but now I'm using L as daily driver.. The only thing I really miss from AK kernel (one of my favorites for mako) is GPU undervolt..

I also noticed that threads about governors are quite outdated.. A micro guide to explain which are performance/battery/balanced oriented will be welcome! XD

i agian install 64u kernel..and i was using daydream clock on charging may be that was causing heating sorry abt that..now the temp is around 47 degree approx.....but i have one problem in synapse i attach the screenshot when i close synapse and open it...it reset defer sampling all the time......thanx for listening:laugh::eek:
should i use your ukm

@apb_axel needs to fix UKM, setting this via terminal works fine, my UKM is outdated, use UKM 3.1 since my changes went into 3.1

@defconoi nice work here, checking it out now.

I noticed that the init.d support is done through install-recovery-2.sh, which doesn't get run with clockworkmod's superuser. Perhaps consider using term-init in the installer, as it won't overwrite anything and installs correctly for both SuperSU and superuser?

    Commit History

    My kernel now deletes /system/bin/mpdecision and /system/bin/thermald which are not needed and interfere with my kernel and automatically removes older busybox, installs latest busybox as well as runs a cleaning script to reset Synapse, FauxClock & Others to make sure the kernel boots up properly without bad settings. FauxClock & Synapse do have a profile saving feature, use that before flashing.

    Older Kernel Builds Here

    Alucard, Darkness & Nightmare CPU Freq Tunables:

    inc_cpu_load_at_min_freq:
    This threshold is used as up threshold while sampling at frequencies less than freq_for_responsiveness. Above that, normal inc_cpu_load is used.

    Tips/Tricks:
    This Works great with Temasek CM11 here
    Also was especially designed and optimized for Android L here
    Also works with CM11/CAF based ROM's, flash the CM11 kernel.

    Other governors have been added so you have full control in tweaking your device:
    SmartMax, Wheatley and OndemandPlus are more battery efficient than Intelliactive that is default, to compensate with intelliactive, undervolt

    Setting a Higher Hysteresis value for IntelliPlug will help with battery, lowering it will improve performance.

    Lowering the Intelliactive Boost cores can save battery.

    99% of the Kernel features of this rom can be customized and set automatically on boot via init.d, you don't need Synapse if you are a cmd line pro and want to save a little bit of processor time/battery:

    Available CPU Governors Explained:

    IntelliActive
    Based off Google's Interactive governor with the following enhancements:

    1. self-boost capability from input drivers (no need for PowerHAL assist)
    2. two phase scheduling (idle/busy phases to prevent from jumping directly to max freq
    3. Checks for offline cpus and short circuits some unnecessary checks to improve code execution paths

    Intellidemand:
    Intellidemand aka Intelligent Ondemand from Faux is yet another governor that's based on ondemand. Unlike what some users believe, this governor is not the replacement for OC Daemon (Having different governors for sleep and awake). The original intellidemand behaves differently according to GPU usage. When GPU is really busy (gaming, maps, benchmarking, etc) intellidemand behaves like ondemand. When GPU is 'idling' (or moderately busy), intellidemand limits max frequency to a step depending on frequencies available in your device/kernel for saving battery. This is called browsing mode. We can see some 'traces' of interactive governor here. Frequency scale-up decision is made based on idling time of CPU. Lower idling time (<20%) causes CPU to scale-up from current frequency. Frequency scale-down happens at steps=5% of max frequency. (This parameter is tunable only in conservative, among the popular governors)
    To sum up, this is an intelligent ondemand that enters browsing mode to limit max frequency when GPU is idling, and (exits browsing mode) behaves like ondemand when GPU is busy; to deliver performance for gaming and such. Intellidemand does not jump to highest frequency when screen is off.

    Pegasusq

    The Pegasus-q is a multi-core based on the Ondemand governor and governor with integrated hot-plugging.
    Ongoing processes in the queue, we know that multiple processes can run simultaneously on. These processes are active in an array, which is a field called "Run Queue" queue that is ongoing, with their priority values ​​arranged (priority will be used by the task scheduler, which then decides which process to run next).

    To ensure that each process has its fair share of resources, each running for a certain period and will eventually stop and then again placed in the queue until it is your turn again. If a program is terminated, so that others can run the program with the highest priority in the current queue is executed.

    Nightmare
    A PegasusQ modified, less aggressive and more stable. A good compromise between performance and battery.
    In addition to the SoD is a prevention because it usually does not hotplug.

    HYPER
    The Hyper (formerly known as kenobi) is an aggressive smart and smooth, optimized for SGS2 getweakt and, based on the Ondemand, which was getweakt of Arighi and was equipped with several features of Ondemandx suspend imoseyon. (Added by sysfs, the settings suspend_freq and suspend Imoseyon's code) is the behavior of the hyper Ondemand if he is in action, very similar. He also has the Arighi's fast_start deep_sleep and detection features. In addition, the maximum frequency is in suspend mode 500Mhz.

    SmartMax
    Well - you did it it 100% correct :)

    Some more info

    The basic idea - which comes from smartass - is the concept of an "ideal" frequency.

    The following strategy is used:
    1) If load is above upper-threshold and current frequency is below ideal freq
    -> jump to ideal in one step
    2) If load is above upper-threshold and current frequency is at or above ideal freq
    ->do "ramp up" steps which will include all frequencies for a specific
    amount of time - so compared to ondemand no "jumping" to max frequency
    3) if load is below lower-threshold and current frequency is below ideal freq
    ->do "ramp down" steps
    4) if load is below lower-threshold and current frequency is above ideal freq
    -> jump down to ideal in one step

    All those thresholds ramp steps and frequency stepping times are
    fully configurable using sysfs. By default I tried to create a good balance.

    The ideal frequency for "us" is 475000 which is the maximal frequency
    of the LP mode of the tegra chip. This will allow using LP mode as much as possible

    Additional to make it "snappy" smartmax has "touch poke"
    So input events from the touchscreen will boost the cpu for a specific
    time to a specific frequency.

    BluActive:
    Based of Google, CAF, CM, myfluxi and franciscofranco Interactive by @eng.stk

    Wheatley:
    Building on the classic 'ondemand' governor is implemented Wheatley governor. The governor has two additional parameters:
    target_residency - The minimum average residency in µs which is considered acceptable for a proper efficient usage of the C4 state. Default is 10000 = 10ms.
    allowed_misses - The number sampling intervals in a row the average residency is allowed to be lower than target_residency before the governor reduces the frequency. This ensures that the governor is not too aggressive in scaling down the frequency and reduces it just because some background process was temporarily causing a larger number of wakeups. The default is 5.
    Wheatley works as planned and does not hinder the proper C4 usage for task where the C4 can be used properly .
    For internet browsing the time spend in C4 has increased by 10% points and the average residency has increased by about 1ms. I guess these differences are mostly due to the different browsing behaviour (I spend the last time more multi-tabbing). But at least we can say that Wheatley does not interfere with the proper use of the C4 state during 'light' tasks. For music playback with screen off the time spend in C4 is practically unchanged, however the average residency is reduced from around 30ms to around 18ms, but this is still more than acceptable.
    So the results show that Wheatley works as intended and ensures that the C4 state is used whenever the task allows a proper efficient usage of the C4 state. For more demanding tasks which cause a large number of wakeups and prevent the efficient usage of the C4 state, the governor resorts to the next best power saving mechanism and scales down the frequency. So with the new highly-flexible Wheatley governor one can have the best of both worlds.
    Obviously, this governor is only available on multi-core devices.

    OnDemandPlus:
    A governor based off of OnDemand and Interactive. It provides a balance between performance, and saving battery.
