CPUID information about ARMv8 core

ocean over 10 years ago

Hi experts,

I want to know if there are CPUIDs information in CHI interface about IP A53/57 Mpcore? and can CCN504 transfer the CPUIDs to Slave device? for example, AXI_USER？

Thanks.

The Cortex-A53 and Cortex-A57 use the transaction ID to report the core.

Thanks Martin, there are CPUIDs information in the links you provided.
I also want to know if CCN504 passthrough the CPUIDs. If there is a device which need CPUIDs, can CCN504 transform the transaction ID to AXI_USER?
