Abstract: A processing device includes a core to execute instructions, and memory management circuitry coupled to, memory, the core and an I/O device that supports page faults. The memory management circuitry includes an express invalidations circuitry, and a page translation permission circuitry. The memory management circuitry is to, while the core is executing the instructions, receive a command to pause communication between the I/O device and the memory. In response to receiving the command to pause the communication, modify permissions of page translations by the page translation permission circuitry and transmit an invalidation request, by the express invalidations circuitry to the I/O device, to cause cached page translations in the I/O device to be invalidated.

Abstract: Various systems and methods for computer memory overcommitment management are described herein. A system for computer memory management includes a memory device to store data and a mapping table; and a memory overcommitment circuitry to: receive a signal to move data in a first block from a memory reduction area in the memory device to a non-memory reduction area in the memory device, the memory reduction area to store data using a memory reduction technique, and the non-memory reduction area to store data without any memory reduction techniques; allocate a second block in the non-memory reduction area; copy the data in the first block to the second block; and update the mapping table to revise a pointer to point to the second block, the mapping table used to store pointers to memory device in the memory reduction area and the non-memory reduction area.

Abstract: Various systems and methods for computer memory management are described herein. A system includes a memory controller to: monitor utilization of a memory device, the memory device used with a memory compression technique; determine that the utilization of the memory device violates a threshold; and initiate a system interrupt to provoke a response, responsive to the utilization of the memory device violating the threshold.
