Abstract
The described technology provides a method including generating a full tracking vector wherein each bit of the full tracking vector indicates cache validity state of a coherence granule (cogran) in agent cache for a related agent, dividing the tracking vector into a plurality of partial vectors (PVECs), for each PVEC, determining whether cache validity state of at least one bit in the PVEC is set to valid, and in response to determining that cache validity state of at least on bit in a given PVEC is set to valid, storing the given PVEC and its PVEC pointer in a tracking_info field of a base snoop filter (SFT) entry for the cogran, wherein the PVEC pointer indicates the location of the given PVEC in the full tracking vector.
