Independent shared and process virtual address translations

A method comprising:

• receiving, by a processor, a virtual address to be translated to a corresponding physical address;
• selecting, by the processor, one of a shared virtual address space register that points to a shared virtual address space and a private virtual address space register that points to a private virtual address space to translate the received virtual address to the corresponding physical address, wherein the shared virtual address space corresponds to a first set of memory sections and the private virtual address space corresponds to a second set of memory sections;
• implementing, by the processor, the selected one of the shared virtual address space register and the private virtual address space register to translate the received virtual address to the corresponding physical address;
• tracking a shared virtual address space identifier (SVID) of a currently active shared virtual address space register and a private virtual address space identifier (PVID) of a currently active private virtual address space register;
• determining whether a translation of an address was obtained from a page table pointed to by the shared virtual address space register or a page table pointed to by the private virtual address space register;
• and
• inputting an entry in a translation lookaside buffer corresponding to one of the SVID and the PVID for the translated address based on the determination of whether the translation of an address was obtained from the page table pointed to by the shared virtual address space register or the page table pointed to by the private virtual address space register.

A non-transitory computer readable medium on which are stored machine readable instructions that when executed by a processor cause the processor to:

• receive a virtual address to be translated to a corresponding physical address in a physical memory;
• select one of a shared virtual address space register that points to a shared virtual address space and a private virtual address space register that points to a private virtual address space to translate the received virtual address to the corresponding physical address, wherein the shared virtual address space corresponds to a first set of memory sections and the private virtual address space corresponds to a second set of memory sections;
• implement the selected one of the shared virtual address space register and the private virtual address space register to translate the received virtual address to the corresponding physical address;
• track a shared virtual address space identifier (SVID) of a currently active shared virtual address space register and a private virtual address space identifier (PVID) of a currently active private virtual address space register;
• determine whether a translation of an address was obtained from a page table pointed to by the shared virtual address space register or a page table pointed to by the private virtual address space register;
• and
• input an entry in a translation lookaside buffer corresponding to one of the SVID and the PVID for the translated address based on the determination of whether the translation of an address was obtained from the page table pointed to by the shared virtual address space register or the page table pointed to by the private virtual address space register.
