Cavium mips64 perf counters

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I'm trying to calculate de CPU load by access the performance counters
in mips and I haved reading in the cp0 but my problem is that I cannot
find documentation about the real meaning of these counters :

1.-LOG_PERF_CNT_NISSUE : ¿means cycle with no issue?

2.-LOG_PERF_CNT_SISSUE : ¿means cycle with     issue?

3.-LOG_PERF_CNT_DISSUE: ¿means cycle with double issue?


so CPU load will be == 2*100/(1+2) , in the period of time.

any clue...



thanks
