  • Patent number: 11169929
    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.

  • Patent number: 10733108
    Abstract: A system for computer memory management that implements a memory pool table, the memory pool table including entries that describe a plurality of memory pools, each memory pool representing a group of memory pages related by common attributes; a per-page tracking table, each entry in the per-page tracking table used to related a memory page with a memory pool of the memory pool table; and processing circuitry to: scan each entry in the per-page tracking table and, for each entry: determine an amount of memory released if the memory page related with the entry is swapped; aggregate the amount of memory for the respective memory pool related with the memory page related with the entry in the per-page tracking table, to produce a per-pool memory aggregate; and output the per-pool memory aggregate for the memory pools related with the memory pages in the per-page tracking table.

  • Publication number: 20190303281
    Abstract: Various systems and methods for controlling memory traffic flow rate are described herein. A system for computer memory management, the system comprising: rate control circuitry to: receive a rate exceeded signal from monitoring circuitry, the rate exceeded signal indicating that memory traffic flow from a traffic source exceeds a threshold; receive a distress signal from a memory controller that interfaces with a memory device, the distress signal indicating that the memory device is oversubscribed; and implement throttle circuitry to throttle the memory traffic flow from the traffic source when the rate exceeded signal and the distress signal are both asserted.
