How to disable little cores on the hikey960


#1

hi,
is there someone who knows how to disable 4 little cores of CPU on the hikey960?
the reason is that I want to do special testing on hikey960, but I only need to let my testing case run on the
big cores.
thanks in advance!

You can probably use the CPU hotplug framework to “unplug” them.
