Publication number: 20250130944Abstract: The present disclosure provides a cache status recording method. The method is applied to a probe filter, wherein a host cache record table is configured in the probe filter, the host cache record table is used for recording a status of cache data of a host in a host cache and a peripheral sharing identifier corresponding to the cache data, the peripheral sharing identifier is used for indicating whether the cache data is shared by a peripheral device. The method includes: when the peripheral device shares the cache data in the host cache, updating the peripheral sharing identifier such that the peripheral sharing identifier indicates a corresponding cache data is shared by the peripheral device; and when a processor core exclusively owns the cache data, updating the peripheral sharing identifier such that the peripheral sharing identifier indicates the corresponding cache data is not shared by the peripheral device.Type: ApplicationFiled: September 1, 2023Publication date: April 24, 2025Inventors: Xiangjun Xu, Jiaming Wei
