CONFIG_HV_RAM_START

2M-aligned Start physical address of the RAM region used by the hypervisor

Type: hex

Help

A 64-bit integer indicating the base physical address where the hypervisor should be loaded. If RELOC is disabled, the bootloader is required to load the hypervisor to this specific address. Otherwise the hypervisor will not boot. With RELOC enabled the address will be referred as the lowest possible address that hypervisor be loaded, hypervisor may relocate its symbols to where it is placed, and thus the bootloader might not place the hypervisor at this specific address. Note that the addr demands 2M aligned, otherwise memory corruption may occur.

Defaults
