Is Symmetric Multi-Processing (SMP) supported on Stellar SR6 P7 R52+ cores

[swu.1]

There are several R52+ cores available in Stellar SR6 P7 line, e.g. SR6P7C8.

I have question about the Symmetric Multi-Processing (SMP) support on these R52+ cores. Is SMP available inside R52+ cluster or among R52+ clusters?

Hello,

SMP is a matter of Operating System.

SR6P7 devices provides support for SMP Real Time Operating Systems.

There is no MMU so Linux OS cannot be supported.

Thanks Giuseppe,

​

SMP require hardware coherent for both CPU/Core, actually I found the atomic operation issue at following page,

Do you have any idea?

Thanks
