Reading the code you should see the max getting initialized in hypervisor/mmio.c mmio_cell_init. For your benchmarks you will have to modify jailhouse. Incrementing that number statically or somehow deriving the number from the cell config. And you will have to register an mmio-handler for such regions. Depending on what you measure that will probably just pass-through. > Steps to reproduce: > Add a memory region with size 0x100 to your non-root cell > configuration. load, start, disable jailhouse > > Thanks and Best Regards > Andreas > > -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
