Possible to isolate cores into 2 groups with A720 + DSU-120

yifanfeng

I am reading A720 + DSU-120 TRM nowadays, and wonder if it is possible to isolate cores into 2 groups with A720 + DSU-120. Here is the idea: 

Core0 （A720）
Core2
Core4
Core6
Core8 （ECC）
Core10（ECC）
Core1
Core3
Core5
Core7
Core9（ECC）
Core11（ECC）
                                                                              DSU-120 （ECC）
  
Two typical scenarios:
Scenario#1: Fully Virtualization
All cores in the cluster work in virtualization mode and managed by a single hypervisor.
Scenario#2: 'HW' Isolation Mode (ASIL-B)
Core0-Core7 as group1, works in virtualization mode and managed by hypervisor.
Core8-Core11 as group2, in SMP, running rich OS, such as Linux.
Cache partitioning and bandwidth partitioning enabled to isolate group1 and group2.

Does this idea works?
