Abstract

In accordance with the described techniques for extended attributes for shared page tables, a device includes an accelerator device and a memory management unit that maintains a first set of page tables and a second set of page tables. The second set of page tables includes extended attributes for accessing data that the accelerator device operates on. The memory management unit is configured to receive a virtual memory address, and translate the virtual memory address to a physical memory address using the first set of page tables. In addition, the memory management unit retrieves the extended attributes from the second set of page tables. In this way, data is accessed from the physical memory address based on the extended attributes.
