Sometimes, a small change in a hot function reducing the cycles of
this function, but the overall workload doesn't get faster. It is
interesting where the cycles are moved to.
What it would like is to diff before/after streams. The stream is the
branch history which is aggregated by the branch
Stream is the branch history which is aggregated by the branch
records from perf samples. Now we only support the callchain as
stream.
If the callchain entries of one stream are fully matched with
the callchain entries of another stream, we think two streams
are matched.
For example,
cycles:
We have used callchain_node->hit to measure the hot level of one
stream. This patch calculates the sum of hits of total streams.
Then in next patch, we can use following formula to report hot
percent for one stream.
hot percent = callchain_node->hit / sum of total hits

In previous patch, we have created an evsel_streams for one event,

a pair. From the pair, we can know

We show the streams separately. They are divided into different sections.
1. "Matched hot streams"

For example,

For TMU v2, TMSAR registers need to be set properly to get the

Also the temperature read needs to be converted to degree Celsius
