This makes the 'damon-dbgfs' to support the physical memory monitoring, in addition to the virtual memory monitoring. Users can do the physical memory monitoring by writing a special keyword, 'paddr' to the 'target_ids' debugfs file. Then, DAMON will check the special keyword and configure the monitoring context to run with the primitives for the physical address space. Unlike the virtual memory monitoring, the monitoring target region will not be automatically set. Therefore, users should also set the monitoring target address region using the 'init_regions' debugfs file. Also, note that the physical memory monitoring will not automatically terminated. The user should explicitly turn off the monitoring by writing 'off' to the 'monitor_on' debugfs file.

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 Restructured Text 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.
