A0 and B0 chips have different performance characteristics when it comes to the hypervisor because B0 waits for SysMMU_SYNCs to complete during every memory ownership transaction. Set debug.hypervisor.metrics_tag=hwrev_a0 on PROTO1.x and EVT1.0 devices. EVT1.1 and later are B0 and benchmarks are representative of production devices. This is only done on userdebug/eng builds. Test: 'getprop | grep hypervisor' on A0/B0 devices Change-Id: I0c81a0e4706a13cd63358de23048087a9190b9da
