This patchset implements a new feature that collects hist entries in a
hierachical manner. That means lower-level entries are belonged to an
upper-level entry. The entry hierachy is built on the sort keys
given, so users can set it whatever they want. It only shows
top-level entries first, and user can expand/collapse it dynamically.
This is only implemented in --gtk currently, since it's well-matched
to the GTK tree view widget and I didn't want to be bothered with the
TUI browser code at this stage. :)
Can use this infrastructure to support call-graphs in the GTK UI?
Yes, I think it's doable. I don't have an idea how to use both of the
features at the same time though. Anyway, I'll try to add support for
callchains later.
So I think hierarchy view makes tons of sense but it needs to be
orthogonal with call-graphs. Preferably in such a way that if you have
both hierarchy view and call-graphs enabled, you can seamlessly drill
down from process level all the way to call-graph leaf nodes.
