This release is still in beta stage. Report if there are any problems.
Tesla Hotplug: Dynamic hotplug for hammerhead, based off of intelli_plug by faux123, some fixes, improvements, new features and tunables, but the main feature is optimization. Manages the cpu better but I'm not completely finished and so it's not 100% stable or featured yet (hence the term beta). You cannot edit the hotplug settings in kernel adiutor, so use the config file (recommended) or synapse.
MSM-Thermal-X: My thermal solution, workaround for stock thermal driver overheads. Should finally fix some issues with the max cpu frequency resulting from inefficient thermal throttling. You can also set custom temperature throttle limits with synapse or kernel adiutor in thermal settings.
KSM-Kernel Samepage Merging: New feature that allows you to highly reduce memory usage, with very marginal impact on cpu usage.
CPU Deferred-Timers: New feature that reduces cpu usage at a very marginal cost of memory usage.
-Linux 3.4.108
-Revert PM-Suspend Freeze to prevent processes from running when device is idle.
-Partial resume suspend_again mechanism

Electroactive governor
The Electroactive CPU governor has been created to get some of the best balances between battery life and performance that you will see on a device. It includes some extra additions and enhancements to be more battery saving than interactive governor and some boost tunes and additions that allow better power management and performance in games as well as better power saving when in normal use. CPU boost, fast_start deep_sleep and detection features are built in as well as 500 MHz clock speed in suspend. Some tunables available in the governor(these can also be tuned in any kernel management app):
boostpulse: Immediately boost speed of all CPUs to hispeed_freq for min_sample_time, after which speeds are allowed to drop below hispeed_freq according to load as usual.
boosted_sampling_down_factor: This custom made parameter's set default setting will give several 0.4 second bursts of full throttle CPU to programs. It's about the time that user interface has to produce some meaningful response to your input so to feel smooth, especially while gaming. Besides better responsiveness, this setting will also give better overall speed to many programs which often interchange high CPU demand with IO waits and then suffer because the CPU governor too eagerly throttled down the frequency during those waits.
default_freq_boost_time: this is the default time that the CPU will spend in 'boost mode' before scaling down to normal frequencies, such as when in normal use.
down_differential: After spending sampling_down_factor*sampling_rate micro seconds at maximum frequency on high load, governor samples the load again to calculate an approx target frequency to scale-down-to which should not trigger up_threshold in the next sample. (Triggering up threshold may cause jumping to max frequency again). Max_load_freq is checked against (up_threshold - down_differential) * current frequency. If found to be smaller, CPU is scaled down to a target frequency as described above. Down_differential also act as the factor to prevent aggressive scale down. Higher value of down_differential corresponds to delayed scaling down.
powersave_bias: this parameter takes a value between 0 to 1000. It defines the percentage (times 10) value of the target frequency that will be shaved off of the target. For example, when set to 100 -- 10%, when ondemand governor would have targeted 1000 MHz, it will target 1000 MHz - (10% of 1000 MHz) = 900 MHz instead. This is set to 0 (disabled) by default. When AMD frequency sensitivity powersave bias driver -- drivers/cpufreq/amd_freq_sensitivity.c is loaded, this parameter defines the workload frequency sensitivity threshold in which a lower frequency is chosen instead of ondemand governor's original target. The frequency sensitivity is a hardware reported in a value between 0 to 100% that tells software how the performance of the workload running on a CPU will change when frequency changes.
ignore_nice_load: this parameter takes a value of '0' or '1'. When set to '0' (default), all processes are counted towards the 'cpu utilisation' value. When it's set to '1', the processes that are run with a 'nice' value will not count aka ignored in the overall usage calculation. This is useful if you are running a CPU intensive calculation that you do not care how long it takes to complete as you can 'nice' it and prevent it from taking part in the deciding process of whether to increase your CPU frequency.
freq_for_responsiveness: up threshold considered for sampling load is up_threshold_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_for_responsiveness b) will not trigger down_threshold in the next sample, then the optimal frequency is set to freq_for_responsiveness.
Electroactive (EX based) Configuration File
Kernel defaults are used to build a configuration file, based off of elementalx's original config file. The config file is found at /etc/electroactive.conf. You can edit this file to change kernel settings. Whatever is set in this file will take effect when the device is booted (unless other scripts or apps interfere).
Overclocking
If you want to overclock, then you can set this in the electroactive.conf file found in the /etc folder. If you overclock, the CPU frequency will probably be throttled due to extensive heat, and will act the same as a non-overclocked CPU except with some unpleasant and unnecessary heat. The stock frequencies are fine, unless you want to do some extreme benchmarking or gaming with thermal throttling set to elexcool (flar2, can be set in .conf file) which gives best performance but your device WILL overheat.
fsync
fsync can be disabled if you're looking for the last ounce of performance. If you disable it however there is a slight risk of data loss if your phone shuts off unexpectedly before the filesystems are synced.
Max screen off frequency
The default max screen off frequency is 1190MHz, which is a good balance between limiting the voltage/frequency and the time required to complete tasks while the screen is off. This can be changed manually at /sys/devices/system/cpu/cpu0/cpufreq/screen_off_max_freq
NTFS and exFAT support
This is for anyone who wants to use OTG cable to connect a USB stick or portable hard-drive formatted with Microsoft's NTFS or exFAT filesystems. (Useful for installing and transporting files from your device) You will need Stickmount or a similar app
F2FS support
F2FS support is built into the kernel, however, you will need to flash the F2FS support patch below before installing Electroactive.
Color preset
Some users complain that the Nexus 5 screen has too 'warm' colors, so there are two color presets: stock and slightly cooler. You can edit /etc/electroactive.conf to change the setting on boot.
0 = stock color
1 = slightly cooler color
Sweep2wake (by flar2)
Sweep2wake allows you to turn on your phone by swiping your finger across the screen. There are four sweep actions that will work
Gesture........Value
Sweep right......1
Sweep left........2
Sweep up.........4
Sweep down....8
Add up the values for each gesture you want to enable and put the total in /sys/android_touch/sweep2wake. For example, to enable all gestures, the value is 15 (1+2+4+8). To enable sweep right, sweep left and sweep up, the value is 7 (1+2+4)
/sys/android_touch/sweep2wake
Doubletap2wake
DoubleTap2Wake (DT2W) allows you to wake the device by double tapping anywhere on the screen. This causes significant battery drain, so you choose at your own choice if you want it enabled or not. You can edit /etc/electroactive.conf to change the setting on boot.
0 = disabled
1 = enabled (bottom of screen only)
2 = enabled (full screen)
Sweep2Sleep
Sweep2Sleep allows you to put the device to sleep by sweeping your finger across the navigation bar area. You can choose different directions to swipe. Unlike Sweep2wake, this does not cause any battery drain. You can edit /etc/electroactive.conf to change the setting on boot.
0 = disabled
1 = sweep right
2 = sweep left
3 = sweep left or right
Backlight dimmer
Backlight dimmer allows you to adjust the LCD screen brightness lower than is possible with stock. You can edit /etc/electroactive.conf to change the setting on boot.
0 = disabled
1 = enabled
USB fast-charge
This will allow you to charge at a faster rate when connected to a USB port. The default limit for USB ports is 500ma, this increases it to 900ma. This only works on laptops/desktops/any computer but not the phone's charger. You can edit /etc/electroactive.conf to change the setting on boot.
CPU Hotplug
The CPU Hotplug manages the CPU cores based on changes in CPU load, etc. There are 4 options available in Electroactive Kernel.
0 for stock mpdecision
1 for msm_sleeper
2 for intelli_plug
3 for alucard_hotplug
4 for msm_hotplug
ALL OTHER SETTINGS FOUND IN THE .CONF FILE ARE SELF EXPLANATORY.
*F2FS users:
THIS KERNEL USES YOUR RAMDISK, it will just modify it on the fly while flashing. These changes are so to not create any incompatibilities with roms or other kernels. If you want to use F2FS on your device you must first flash Cl3Kener's F2FS support patch zip file prior to Electroactive Kernel. Also, some things to consider when using F2FS:
Use F2FS in only r/w partitions (/data and /cache).
F2FS in /system does not make any difference and requires selinux to be set to permissive, and Electroactive kernel is enforcing by default, although you can change this in the .config file found in /etc/electroactive.conf, but is still not recommended. -

in test.
davvero interessante per vari aspetti per quanto riguarda il mio stile:
- governor personalizzato dal dev (un nuovo mondo da provare)
- frequenze min e max davvero particolari. chissà che batteria ci verrà fuori con un 300 e un 1100 (più ovviamente governor etc.)
per quanto riguarda le prestazioni, di sicuro sono inferiori a certi kernel come elemental x, code blue. lo stesso franco/hells mi sembrano migliori in questo. abbastanza ovvio visto le frequenze con cui gira, anzi! mi stupisco che il cell non si pianti con sti settaggi xD
insomma e vediamo come andrà xD
per il momento ho aumentato la frequenza massima almeno a 1200etc.
con 1100 non riesco
EDIT GIGANTE: b b b bbaaaallee xD era un fail mio! kernel adiutor si impostava a caso e mi ha messo ste frequenze. non fate caso al mio messaggio, non vale una cicca ed è tutto falso xD -

record. tolto dopo manco mezza giornata xD
mi spiace ma siamo punto e a capo ...
lo flasho con un bel wippone systemone e mi trovo frequenze stranissime e penso sia il governor ... poi per sicurezza azzero i dati di kernel adiutor (che era già pulito e senza configurazioni), riavvio e mi si presenta con altre freq ancora ....
in tutto ciò, scalda da morire.
2 versioni fa mi stava piacendo un sacco ... quella prima non l'ho provata e questa è di nuovo come le prime release.
apprezzo il lavoro del dev ma aspetto ancora e passo ad altro -
