Neighbourhood-level PMU event codes (PRM section 1.3.2, Table 1-4).

Written to mhpmevent7 or mhpmevent8 to select what hpmcounter7 or hpmcounter8 accumulates. The counter is shared across the 8-Minion neighbourhood; when harts program different events the lower mhartid hart’s choice takes precedence.

Variants

NoEvent = 0

No event; counter does not increment.

EtLinkSend = 1

Any Minion sent an ET Link request.

EtLinkRecv = 2

Any Minion received an ET Link response.

CoopLoadSend = 3

A cooperative load request was sent.

CoopLoadInterNeighSend = 4

An inter-neighbourhood cooperative load request was sent.

CoopLoadRecv = 5

A cooperative load response was received.

CoopStoreSend = 6

A cooperative store request was sent.

CoopStoreRecv = 7

A cooperative store response was received.

IcacheReqSend = 8

Any Minion sent a request to the I-cache.

IcacheRespRecv = 9

Any Minion received a response from the I-cache.
