Hello,
I started Emacs, in scratch buffer, I execute `profiler-start`, move
around, then `profiler-report`.
It show me:
```
103 94% - redisplay_internal (C function)
3 2% - eval
2 1% - minions--prominent-modes
2 1% - cl-remove-if-not
2 1% - cl-remove
1 0% cl-ldiff
1 0% - mode--line-format-right-align
1 0% - eval
1 0% - minions--prominent-modes
1 0% - cl-remove-if-not
1 0% cl-remove
6 5% - timer-event-handler
6 5% - apply
6 5% - #<native-comp-function
F616e6f6e796d6f75732d6c616d626461_anonymous_lambda_23>
6 5% jit-lock-context-fontify
0 0% ...
```
I noticed that `redisplay_internal` is consuming 94% of the CPU, but the
sum of the child items below `redisplay_internal` is less than 2%. Where
is the remaining 92% going? I'd like to see a more detailed CPU profile
for `redisplay_internal`.
Is it possible to get a detailed CPU profile for `redisplay_internal`?

No, you cannot, because redisplay_internal is written in C, and
profiler.el can only analyze profiles of Lisp code.
You need to use a tool like prof for profiling C code.
Sorry.

No, you cannot, because redisplay_internal is written in C, and
profiler.el can only analyze profiles of Lisp code.
You need to use a tool like perf for profiling C code.
Sorry.
