Multi-domain hardware memory compression

A computing system, comprising:

• one or more memories;
• and
• a controller configured to manage allocation of the one or more memories to a process based on one or more memory allocation objectives received from an operating system (OS), wherein to manage allocation of the one or more memories to the process, the controller is further configured to:
• determine a quantity of available memory in the one or more memories;
• allocate a portion of the quantity of available memory to the process;
• map the portion that is allocated to the process to a control block among a plurality of control blocks;
• map a plurality of physical pages used by the process to the control block, the plurality of physical pages being associated with a memory managed by the OS;
• and
• determine whether the plurality of physical pages should be compressed based at least in part on a plurality of OS-writeable objective fields contained in the control block and a recency of access scheme associated with the plurality of physical pages.

A method for managing allocation of one or more memories to a process based on one or more memory allocation objectives received from an operating system (OS), the method comprising:

• determining a quantity of available memory in the one or more memories;
• allocating a portion of the quantity of available memory to the process;
• mapping the portion that is allocated to the process to a control block among a plurality of control blocks;
• mapping a plurality of physical pages used by the process to the control block, the plurality of physical pages being associated with a memory managed by the OS;
• and
• determining whether one or more physical pages of the plurality of physical pages should be compressed based at least in part on an OS-writeable objective field contained in the control block.
