Snoop Prefetch Hint
Read cache line in F (or S, if the F state not supported)
Request a cache line in I. Typically issued by I/O proxy
entities, RdCur is used to obtain a coherent snapshot of
an uncached cache line.
Read cache line in either E or F (or S, if F state not
supported). The choice between F (or S) and E is
determined by whether or not per caching agent has
cache line in S state.
Read Invalidate Own requests a cache line in M or E
state. M or E is determined by whether requester is
forwarded an M copy by a peer caching agent or sent an
E copy by home agent.
Peer is left with line in I or S state, and the peer has a
conflicting outstanding request.
Peer has a buried M copy for this line with an outstanding
conflicting request.
Peer has sent data to requestor with no change in cache
state
Peer has sent data to requestor and is left with line in I
state
Peer has sent data to requestor and a WbIData to the
home, and is left with line in I state
Peer has sent data to requestor and is left with line in S
state
Peer has sent data to requestor and a WbSData to the
home, and is left with line in S state
Peer left with line in I-state
Peer has evicted the data with an in-flight WbIData[Ptl]
message to the home and has not sent any message to
the requestor.
Peer left with line in S-state
Peer has sent a WbSData message to the home, has not
sent any message to the requestor and is left with line in
S-state
Snoop Code (get data in F or S state)
- Intel Xeon Processor 7500 Series supports getting data
in F state
