some nitpicks, and more work on the algorithm to build the caller/callee model. I really suggest you look at what I did for heaptrack, since that should work nicely - I just recently fixed a remaining bug therein.

This must not be static, I actually doubt that this algorithm produces the correct results. Please check the current master of heaptrack for how to to this, and test with a recursive test application.
If you need help, let me know. I'll try to find some time later tonight to write a proper unit test for this which you can use then as basis. It's about time I start with unit test coverage, it will make your life much easier.
The problem is the following: The bottom up data contains all call graphs in a "merged" way, but the recursion guard must only be used for individual call graphs. You can get from the "merged" tree of call stacks to a single stack by doing a depth-first search and then bubbling up the parent chain. I.e. the individual stacks are the parent-chains of every leaf in the bottomUpData tree. Now for every individual stack you'll have to guard against repeated counts of costs in the face of recursion, so you'll clear the set whenever you hit the next leaf before bubbling up the parent chain.
The comment I wrote initially didn't explicitly say that, so sorry if that wasn't clear.

this is still potentially counting the same thing multiple times, i.e. when you have a recursive stack
a > b > a > b
then the first two frames will not yet be in the set and thus added to the list, but then the last two frames will get their inclusive cost incremented while that shouldn't be the case for the caller/callee data representation.

I'd say use a FrameData here as "root" which holds the rows in it's children
. The advantage is that this will allow us to track the total cost in the root object, for use in calculating the fractional cost.

you don't need to supply neither index nor parent at all for a QAbstractTableModel. It has default implementations that are fine for us (afaik?)
since this is not a tree, accessing the data is trivial: m_rows.value(index.row())

As it turns out this is half true. True, I didn't need to override parent but I do need to override index, otherwise I get a segfaults in CallerCalleeModel::itemFromIndex.
