Hi Joakim,

Thanks for your reply.

Actually in the meanwhile we have started with a approach to support PSCI handlers inside op-tee code.

We have been able to start the secondary cores via the PSCI_CPU_ON function call and place them into an infinite loop for now. The next phase will involve making the secondaries jump to 'secondary_start' inside the kernel.

If everything pans out properly, we will share the updates and probably some RFC patches for the same.

Hope that is ok.

Regards, Bhupesh

Hi Sumit,

A bit late reply here, but ARM and Linaro are working on this support but don’t have a completion date planned yet (and so far nothing to share either), so I'm afraid you have to wait a bit longer to get anything official.

Also if someone can clarify the standard way to enable ARM PSCI interface for turning-on/off secondary CPUs, it would be very much appreciated.   Thanks and regards, Sumit
