- Nothing.
-
- Count every cycle.
-
- Indicates the number of instructions being completed every cycle
-
- RTCSELECT bit transition. 0 = 47, 1 = 51, 2 = 55, 3 = 63 (bits from the time base lower register).
-
- Number of instructions dispatched
-
- Number of cycles the LSU stalls due to BIU or cache busy.
-
- Number of cycles the LSU stalls due to a full store queue
-
- Number of cycles the LSU stalls due to operands not available in the reservation station
-
- Number of instructions written into the load queue.
-
- Number of cycles that completion stalls for a store instruction
-
- Number of cycles that completion stalls for an unfinished instruction. This event is a superset of
-
- Number of system calls
-
- Number of cycles the BPU stalled as branch waits for its operand
-
- Number of fetch corrections made at the dispatch stage. Prioritized behind the execute stage.
-
- Number of cycles the dispatch stalls waiting for instructions
-
- Number of cycles the dispatch stalls due to unavailability of reorder buffer (ROB) entry.
-

-
- Number of instruction table search operations
-
- Number of data table search operations.
-
- Number of cycles the FPU stalled

- Number of times the BIU forwards noncritical data from the line-fill buffer
-
- Number of data bus transactions completed with pipelining one deep with no additional bus transactions queued behind it
-
- Number of data bus transactions completed with two data bus transactions queued behind
-
- Counts pairs of back-to-back burst reads streamed without a dead cycle between them in data streaming mode
-
- Counts non-/ARTRYd processor kill transactions caused by a write-hit-on-shared condition
-
- This event counts non-ARTRYd write-with-kill address operations that originate from the three castout buffers.
-
- Number of cycles when exactly two castout buffers are occupied
-
- Number of data cache accesses retried due to occupied castout buffers
-
- Number of read transactions from load misses brought into the cache in a shared state
