Could someone explain me what is hotplug and how it works? I also would like to know which I/O Scheduler should I use to improve battery life and what gives Read Ahead Buffer.
Thanks to everyone who could teach me something new

Check AK Kernel thread.

The second post contains links that explain each option.

In regards to schedulers.. It depends on what you do with the phone (i.e. How much time you spend on it, if you multitask or use it for CPU-RAM hungry apps).

In any case the answer will probably revolve around SIO, FIOPS, DEADLINE and ROW (In no particular order).

Lastly, keep in mind that there are certain schedulers that do not play well with specific governors. If in doubt, leave the default kernel configuration as it is.

Happy reading.

when your cpu hotplugs, its turning cores off and on, as it needs to use them.
