Subject: How to let `profiler-report` show more info for `redisplay_internal`?
Date: Mon, 2 Sep 2024 11:02:50 +0800	[thread overview]
Message-ID: <767540f2-aad1-428a-809b-e21dc2fef34e@gmail.com> (raw)

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`?
