Abort Time-out Response
Acknowledge receipt of Data_* and Cmp/FrcAckCnflt,
signal a possible conflict scenario.
In addition to signaling AckCnflt, the caching agent has
also written the dirty cache line data plus any partial
write data back to memory in a WBiData[Ptl] message
and transitioned the cache line state to I.
Uo All snoop responses gathered, no conflicts
Uo Completion with Data
Complete request, forward the line in F (or S) state to the
requestor specified, invalidate local copy or leave it in S
state.
Complete request, invalidate local copy
Complete request, forward the line in E or M state to the
requestor specified, invalidate local copy
Data Response in (FEIMS) state
NOTE: Set RDS field to specify which state is to be
measured.
- Intel Xeon Processor 7500 Series supports getting data
in E, F, I or M state
Data Response in (FEIMS) state, Complete
NOTE: Set RDS field to specify which state is to be
measured.
- Intel Xeon Processor 7500 Series supports getting data
in E, F or I state
Data Response in (FEIMS) state, Force Acknowledge
NOTE: Set RDS field to specify which state is to be
measured.
- Intel Xeon Processor 7500 Series supports getting data
in E, F or I state
Uo Non-Coherent Data
Debug Data
Clean cache line eviction notification to home agent.
Legacy floating point error indication from CPU to legacy
bridge
All snoop responses gathered, force an AckCnflt
Signal completion and Grant E state ownership without
data to an InvItoE or 'null data' to an InvXtoI
Signal FrcAckCnflt and Grant E state ownership without
data to an InvItoE or 'null data' to an InvXtoI
Interrupt acknowledge to legacy 8259 interrupt controller
Ui, Uo Logical mode interrupt to processor
Ui, Uo Physical mode interrupt to processor
Ui, Uo Interrupt priority update message to source interrupt
agents.
Invalidate to E state requests exclusive ownership of a
cache line without data.
Flush a cache line from all caches (that is, downgrade all
clean copies to I and cause any dirty copy to be written
back to memory).
Ui Configuration read from configuration space
Ui Configuration write to configuration space
Read from legacy I/O space
