Title:
VIRTUALIZATION OF PROCESS ADDRESS SPACE IDENTIFIERS FOR SCALABLE VIRTUALIZATION OF INPUT/OUTPUT DEVICES
Document Type and Number:
WIPO Patent Application WO/2018/152688
Kind Code:
A1
Abstract:
A processing device comprises an address translation circuit to intercept a work request from an I/O device. The work request comprises a first ASID to map to a work queue. A second ASID of a host is allocated for the first ASID based on the work queue. The second ASID is allocated to at least one of: an ASID register for a dedicated work queue (DWQ) or an ASID translation table for a shared work queue (SWQ). Responsive to receiving a work submission from the SVM client to the I/O device, the first ASID of the application container is translated to the second ASID of the host machine for submission to the I/O device using at least one of: the ASID register for the DWQ or the ASID translation table for the SWQ based on the work queue associated with the I/O device.
