摘要： A peripheral device includes a bus interface and an Address Translation Service (ATS) controller. The bus interface is to communicate over a peripheral bus. The ATS controller is to communicate over the peripheral bus, including sending address translation requests and receiving address translations in response to the address translation requests, to cache at least some of the address translations in one or more Address Translation Caches (ATCs), to estimate one or more statistical properties of the received address translations, and to configure the one or more ATCs based on the one or more statistical properties.

摘要： A device includes a hardware block to perform a hardware process and internal logic coupled between a processing device, which executes instructions, and the hardware block. The internal logic can one of measure execution time or count clock cycles of at least a portion of the hardware process. The internal logic can further, in response to the measured execution time or the counted clock cycles satisfying a predetermined condition, provide data associated with the one of the execution time measurement or the clock cycles count to the processing device, the data being statistically indicative of a latency of data packets sent by the hardware process over a total time the hardware process executes.

摘要： A compute node includes a memory, a processor and a peripheral device. The memory is to store memory pages. The processor is to run software that accesses the memory, and to identify one or more first memory pages that are accessed by the software in the memory. The peripheral device is to directly access one or more second memory pages in the memory of the compute node using Direct Memory Access (DMA), and to notify the processor of the second memory pages that are accessed using DMA. The processor is further to maintain a data structure that tracks both (i) the first memory pages as identified by the processor and (ii) the second memory pages as notified by the peripheral device.

摘要： A network adapter includes a network interface, a bus interface, a hardware-implemented data-path and a programmable Data-Plane Accelerator (DPA). The network interface is to communicate with a network. The bus interface is to communicate with an external device over a peripheral bus. The hardware-implemented data-path includes a plurality of packet-processing engines to process data units exchanged between the network and the external device. The DPA is to expose on the peripheral bus a User-Defined Peripheral-bus Device (UDPD), to run user-programmable logic that implements the UDPD, and to process transactions issued from the external device to the UDPD by reusing one or more of the packet-processing engines of the data-path.

摘要： An apparatus for cache management includes an interface and a processor. The interface is for communicating with a cache memory configured to store data items. The cache controller is configured to obtain a classification of the data items into a plurality of groups, to obtain respective target capacities for at least some of the groups, each target capacity defining a respective required size of a portion of the cache memory that is permitted to be occupied by the data items belonging to the group, and to cache new data items in the cache memory, or evict cached data items from the cache memory, in accordance with a policy that complies with the target capacities specified for the groups.
