Providing hardware support for shared virtual memory between local and remote physical memory

A non-transitory machine-readable medium having stored thereon instructions, which if performed by a machine cause the machine to perform a method comprising:

• receiving a memory access request including a virtual address;
• analyzing an entry corresponding to the virtual address stored in a translation lookaside buffer (TLB) of a processor to determine if a physical address (PA) corresponding to the virtual address is present in a first memory associated with the processor or a second memory associated with an accelerator coupled to the processor based on a location attribute of the entry that indicates whether the PA is present in the first memory or the second memory, the first memory and the second memory collectively forming a shared virtual memory space;
• and
• if the PA is present in the second memory, sending a reverse proxy execution request to the second memory to perform the memory access request.

A system comprising:

• a processor having a first core including a first memory management unit (MMU), the first MMU including a plurality of entries each to store a virtual address to physical address translation, wherein each entry includes a counter to store a count of a number of accesses by the processor to a memory location of a second memory associated with an accelerator coupled to the processor, wherein when the counter of an entry reaches a threshold value, the processor is to move data stored in the memory location associated with the entry from the memory location of the second memory to a memory location of a system memory coupled to the processor;
• the accelerator coupled to the processor via a link, the accelerator including a second processor and a second MMU;
• and
• the system memory coupled to the processor.
