1. A method for configuring an address translation relationship, the method comprises:
transferring, by a virtual machine manager (VMM) deployed in a rich execution environment (REE) of a computer system, a first address translation relationship to a secure partition manager (SPM) deployed in a trusted execution environment (TEE) of the computer system, wherein the first address translation relationship comprises an address translation relationship from an intermediate physical address (IPA) allocated to a virtual machine (VM) deployed in the REE to a physical address (PA) for the SPM to perform IPA-to-PA address translation based on the first address translation relationship when transmitting data from the SP to the VM, wherein the PA is a memory address.
