Hybrid cache coherency

A method for hybrid cache coherency, the method comprising:

• receiving, by a device, an unrestricted-access read request corresponding to a cache line, the unrestricted-access read request from a first host;
• recording, by the device, an indication of the unrestricted-access read request with respect to the cache line, the indication including an identifier for the first host;
• receiving, by the device, a shared-access read request for the cache line from a second host;
• and
• communicating, by the device, an invalidation request for the cache line to the first host using the identifier for the first host, the invalidation request communicated based on the shared-access read request.

A machine-readable medium including instructions for hybrid cache coherency, the instructions, when executed by processing circuitry of a device, cause the processing circuitry to perform operations comprising:

• receiving an unrestricted-access read request corresponding to a cache line, the unrestricted-access read request from a first host;
• recording an indication of the unrestricted-access read request with respect to the cache line, the indication including an identifier for the first host;
• receiving a shared-access read request for the cache line from a second host;
• and
• communicating an invalidation request for the cache line to the first host using the identifier for the first host, the invalidation request communicated based on the shared-access read request.
