This is also now similar to how we print e820 entries: BIOS-e820: [mem 0x00000000bafda000-0x00000000bb3d3fff] usable BIOS-e820: [mem 0x00000000bb3d4000-0x00000000bdd2efff] reserved BIOS-e820: [mem 0x00000000bdd2f000-0x00000000bddccfff] ACPI NVS BIOS-e820: [mem 0x00000000bddcd000-0x00000000bdea0fff] ACPI data BIOS-e820: [mem 0x00000000bdea1000-0x00000000bdf2efff] ACPI NVS Since this is a debugfs file not used by tools there's no known ABI dependencies.

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.
