kswap0 25% in linux-imx kernel


Mauro Ziliani
 

Hi all
Sometime the kswap0 kernel thread jump to 25% of CPU.

I'm working on imx6dl sabresd derived board.

When this happens the "power" drop down very fast.

I have no swap partition defined and swapon gives  no swap spaces are allocated.
/proc/swaps is empty.

Why kswap0 jump to 25%?

This happens when vm.swappiness is 6

Any idea?
 
The bsp is based on krogoth with qt5.6.1 used for QML

I strongly advise you to move to newer release. We've been using Linux
mainline for i.MX6 in many projects and might be worth checking.
