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.
A cache status recording method, wherein 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, and the method comprises:
A data access method, wherein the method is applied to a probe filter, and the method comprises:
A computer device, comprising a host and a peripheral device, wherein the host comprises a plurality of processor cores and a probe filter, and each processor core is configured with a corresponding host cache;
