ADDRESS TRANSLATION TECHNOLOGIES

Abstract:

Examples described herein relate to an apparatus comprising: at least one processor, when operational, to: perform a command to submit a work descriptor to a device, wherein: submission of the work descriptor causes an attempt to perform a substitution of an address in the work descriptor before submitting the work descriptor to the device. In some examples, the address comprises a guest virtual address (GVA) and the substitution of an address comprises replacement of the GVA with a host physical address (HPA) corresponding to the GVA. In some examples, the at least one processor is to: substitute the address in the work descriptor with an address translation of the address in the work descriptor if the address translation is available for access by a processor that performs the command.
