On PowerPC, in a particular test scenario, all the cpu idle states were

Inspite of this it was observed that the idle state count of the shallowest

This is because the governor returns the idle state index as 0 even in
scenarios when no idle state can

It is possble that a callchain has cycles or recursive calls. In that
case it'll end up having entries more than 100% overhead in the
output. In order to prevent such entries, cache each callchain node
and skip if same entry already cumulated.

Call __hists__add_entry() for each callchain node to get an
accumulated stat for an entry. Introduce new cumulative_iter ops to
process them properly.

The new ->add_entry_cb() will be called after an entry was added to
the histogram. It's used for code sharing between perf report and
perf top. Note that ops->add_*_entry() should set iter->he properly
in order to call the ->add_entry_cb.
Also pass @arg to the callback function. It'll be used b

The report__resolve_callchain() can be shared with perf top code as it
doesn't really depend on the perf report code. Factor it out as
sample__resolve_callchain(). The same goes to the hist_entry__append_
callchain() too.

I think if I sort the files in net-next the problem will go away,
if someone can confirm this I'll do it.

There are a _lot_ of function tracing style
uses of dev_dbg that could/should be deleted.
This patch doesn't attempt to delete them.

The --percentage option is for controlling overhead percentage
displayed. It can only receive either of "relative" or "absolute".
"relative" means it's relative to filtered entries only so that the
sum of shown entries will be always 100%. "absolute" means it retains
original value before and af
Now perf report will show absolute percentage on filter entries by
default.

When filtering by thread, dso or symbol on TUI it also update total

with filter.

Add report.percentage option for setting default value of the
symbol_conf.filter_relative. It affects the report output only if a
filter applied.
An user can write .perfconfig file like below to show absolute
percentage of filtered entries by default:
$ cat ~/.perfconfig
[report]
percentag
Currently if a sample was filtered by command line option, it just
dropped. But this affects final output in that the percentage can be
different since the filtered entries were not included to the total.
But user might want to see the original percentages when filter
applied so change the behavi
