Abstract
Disclosed embodiments relate to improved heterogeneous CPUID spoofing for remote processors. In one example, a system includes multiple processors, including a first processor including configuration circuitry to enable remote processor identification (ID) spoofing; fetch circuitry to fetch an instruction; decode circuitry to decode the instruction having fields to specify an opcode and a context, the opcode indicating execution circuitry is to: when remote processor ID spoofing is enabled, access a processor ID spoofing data structure storing processor ID information for each of the plurality of processors, and report processor ID information for a processor identified by the context; and, when remote processor ID spoofing is not enabled, report processor ID information for the first processor; and execution circuitry to execute the instruction as per the opcode.
