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.

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 1216 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.
