How to disable 2 cores on SABRE for SD board

[wpflueger]

I'm evaluating the yocto linux distro on the sabresd board with i.mx6Quad processor.

Now I want to test the performance with a dual core processor.

How can I switch off 2 cores to get the dual core performance tested?

You can disable cores in /sys/devices/system/cpu

For instance to disable CPU2  : echo 0 > /sys/devices/system/cpu/cpu2/online
