The original delaytop only supported static output with limited interaction. Users had to restart the tool with different command-line options to change sorting or display modes, which disrupted continuous monitoring and reduced productivity during performance investigations. Adds real-time interactive controls through keyboard input: 1) Add interactive menu system with visual prompts 2) Support dynamic sorting changes without restarting 3) Enable toggle of memory verbose mode with 'M' key The interactive mode transforms delaytop from a static monitoring tool into a dynamic investigation platform, allowing users to adapt the view in real-time based on observed performance patterns.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
