• Category: TRACKER Events
• Event Code: 0x06
• Max. Inc/Cyc: 1, Register Restrictions: 0-3
• Definition: Counts the number of allocations into the local HA tracker pool. This can be used in
conjunction with the occupancy accumulation event in order to calculate average latency. One can-
not filter between reads and writes. HA trackers are allocated as soon as a request enters the HA

response is returned on the ring.

Filter for outbound NDR transactions sent on the AD ring. NDR
stands for "non-data response" and is generally used for completions
that do not include data. AD NDR is used for transactions to remote
sockets.
SNP bxxxxxx1x Snoops:
Filter for outbound SNP transactions sent on the ring. These
transactions are generally snoops being sent out to either remote or
local caching agents. This should be zero if Early Snoop is enabled.
