Abstract
Device memory protection for supporting trust domains is described. An example of a computer-readable storage medium includes instructions for allocating device memory for one or more trust domains (TDs) in a system including one or more processors and a graphics processing unit (GPU); allocating a trusted key ID for a TD of the one or more TDs; creating LMTT (Local Memory Translation Table) mapping for address translation tables, the address translation tables being stored in a device memory of the GPU; transitioning the TD to a secure state; and receiving and processing a memory access request associated with the TD, processing the memory access request including accessing a secure version of the address translation tables.
