Hello
By default VSDK Linux uses both the A15 in SMP mode, no need to do any separate configuration here. Even if the cfg file has set PROC_A15_0_INCLUDE=yes, the Linux kernel uses both the A15 cores and this is abstracted from the application.

Hello
All the demos of vision SDK HLOS (Linux) uses dual A15.
For the user/application its appears to be as a single A15 core, but underneath the OS uses both A15 cores in SMP mode.
You can think as a single A15 core with CPU clock/frequency doubled.
