Yes, the "big" A72 cores are affected.

Arm CPUs [that] are not vulnerable... include Cortex-A76, Cortex-A53, Cortex-A55, Cortex-A32, Cortex-A7 and Cortex-A5.

Hope the N3 is Cortex-A76

Yes, thus "N3" is where hope lies... but pinning VMs, containers, etc to the small cores of a RK3399 seems like the best immediate solution.

ug, conflicting info, I guess A55 is the best safe one then.
or the A53 24 core. The issue with the last link is it doesn't explicitly list the safe one minute just omits some.
