monitoring of branch ratios on cores doing busy polling using PMDs as
described below:
-``--core-list {list of cores}``
+``--core-branch-ratio {list of cores}:{branch ratio for listed cores}``
Specify the list of cores to monitor the ratio of branch misses
to branch hits. A tightly-polling PMD thread has a very low
branch ratio, therefore the core frequency scales down to the
minimum allowed value. On receiving packets, the code path changes,
causing the branch ratio to increase. When the ratio goes above
the ratio threshold, the core frequency scales up to the maximum
- allowed value.
-
-``--branch-ratio {ratio}``
- Specify a floating-point number that identifies the threshold at which
- to scale up or down for the given workload. The default branch ratio
- is 0.01 and needs adjustment for different workloads.
