You can use arm_cortex_a9_get_multiprocessor_cpu_id() in all
configurations.
Please try to use the functions in <libcpu/arm-cp15.h> in your BSP. If
missing, then add them.
I've tried this approach. The cortex-a15 manual states:
"CPU ID
Indicates the processor number in a Cortex-A15 multiprocessor system. For:
one processor, the CPU ID is 0x0 [1]."
In the Jailhouse single processor configuration this method does not work.
Why does it not work?
If you have a single processor, then why do you need this anyway?
