This post refers only to previous 2016.03.19 versions

Cpu boot at 1200 MHz.

Gpu boot at 384 MHz.

Undervolt.

Boot with 'pegasusq' as cpufreq governor.

Boot with 'sio' as block scheduler.

Boot with 'slqb' as allocator.

CPU overclock selectable up to 1480 MHz.

GPU overclock selectable up to 512 MHz.

PowerVR SGX 540 kernel modules blob build 1.9@2291151

Last ducati-m3.bin firmware supported.

Without debug code.

SElinux Support.

SNAPPY and LZ4 compression libs for SWAP soported.

Activated ZRAM with LZ4 compression

Tweaked Init process.

Android F2 File system (F2FS) support.

Union file system (AUFS) support.

Windows NTFS support

Windows CIFS support.

Unix/Linux NFS support.

Windows exFAT support.

ISO 9660 support.

UDF DirectCD and CDRW/DVD support.

Apple HSFS and HSFS+ R/W support.

DIrectories /mnt/mntpoint1, /mnt/mntpoint2 and /mnt/mntpoint3 suitables for your needs.

Battery images replaced.

Manages /etc/init.d/ and /etc/sysctl.conf.

Init's improvements built in kernel.

I think it does not need further sysctl.conf tweaks.

GENERAL NOTES:

Booting pegasusq because it is very soft with frequency scaling and looks as good compromise between performance and battery saving.

Naturally, each user should choose the one that best suits your needs.

This kernel not use and remove, if any when it installs, /system/lib/hw/power.*.so, as they are redundants here and interfere with CPU's

management frequency, increasing eat CPU cycles.

User can insert boot actions by scripts in /etc/init.d. Here, it is important to establish the order of execution starting with numbers script names,

to run always the latter that has the largest number.

With this kernel, the user not need a separate script to run at the end of the boot.

Has been included an interface to the OC of the GPU, using "cat /sys/devices/system/cpu/cpu0/cpufreq/gpu_frequency"' command to view current frequency.

Kernel will stop secundary processor when its performance is not necessary for the functioning of the tablet.

Maybe I can tune a little more, but for now the second processor still remain stopped with low power requirement, even the first reaches 600 MHz.

I have further reduced the working voltage used by the Core, GPU, and CPU frequencies up to 1200 MHz.

I have completely replaced the memcopy & memmove functions code for memory data movement. The new code can be up to 10 times faster.

I have lately added several optimizations to improve performance and reduce overhead.

DhollmenL : Lollipop versions

DhollmenK : Kit-Kat versions

If your Rom have problems after installing kernel, you must install the blobs file.
