MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202617074633 A) filed by Advanced Micro Devices, Inc. on June 16, 2026, for Adaptive System Probe Action To Minimize Input/Output Dirty Data Transfers.
Inventors include Ou, Li; Balakrishnan, Ganesh; and Apte, Amit.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: Adaptive system probe action to minimize input/output dirty data transfers is described. In one or more implementations, a system includes a processor, a memory configured to store data, and a cache configured to store a portion of the data stored in the memory for execution by the processor. The system also includes a cache coherence controller including a cache line history. The cache coherence controller is configured detect a direct memory access request from an input/output device. The direct memory access request is associated with an input/output operation involving the data. The cache coherence controller is further configured to identify a cache line associated with the direct memory access request, and, in response to the cache line history including a dirty data transfer record corresponding to the cache line, selectively send a probe to the cache based on a state of the cache line.
