Hi,
I'm using a Juno r1 board and I'm trying to get processor's related CPU ID without using any header file like function sched_getcpu from sched.h.
The reason is I want to get the CPU number for TrustZone application and there is no way to using those header files.
I know there is an instruction CPUID which could be used in x86 for this purpose, so I'm wondering is there any instruction I could use for ARMv8-A?
Thanks.
Simon
