On some systems /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us or /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us return a file error because of bad ACPI LPIT data from a misconfigured BIOS. turbostat interprets this failure as a fatal error and outputs turbostat: CPU LPI: No data available If the ACPI LPIT sysfs files return an error output a warning instead of a fatal error, disable the ACPI LPIT evaluation code, and continue.

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.
