Default [KERNEL][DISCONTINUED] Quasar 2.2 v8 (for Nova & stock ROMs)

A quasi-stellar radio source ("quasar") is a very energetic and distant active galactic nucleus. Quasars are extremely luminous and were first identified as being high redshift sources of electromagnetic energy, including radio waves and visible light, that were point-like, similar to stars, rather than extended sources similar to galaxies.

~~~

Quasar is the kernel that comes with Nova ROM. It's based on LG sources but improved where possible and increased in features. It's a very progressive work. The first releases may also be experimental, we need to test out which changes are for better and which ones are for worse; I hope you can all help me with this task.

Now available for stock ROMs!

Download: Quasar v8 > DO NOT FLASH THIS ON NOVA
Instructions: Flash in custom recovery, no wipes needed. (For this version there's no OC support)

How can I test which governor or I/O scheduler is better for my device?

I tried quadrant and I get lower score with savagedzen governor + V(R) I/O than the default setting...

Ignore quadrant. It's unreliable and fluctuates a lot.
These things happen in the background.

It's daily usage that will tell you which one is better.

It's too troublesome.

The ramdisk for nova and stock is different and I don't feel like releasing 2 versions each time a new Quasar gets out. I could share the zImage and let someone else get it to a flashable boot.img though.
