Hello M5 developers -- I noticed comments in a couple places in the functional unit code that indicate that a functional unit (or, rather, an opClass) should have its issue latency set to either 1 or its opLatency (in the comment at line 54 of src/cpu/o3/fu_pool.hh, for example). However, in the default FuncUnitConfig.py, the IntDiv opClass has opLat == 20 and issueLat == 19, which doesn't seem to match these statements.
Question: are the comments out of date, or should the issue Latency be 20 on the IntDiv unit? Thanks! -Vilas
