Real-time Linux Analysis tool

:Manual section: 1

SYNOPSIS
========
**rtla** *COMMAND* [*OPTIONS*]

DESCRIPTION
===========
The **rtla** is a meta-tool that includes a set of commands that aims to
analyze the real-time properties of Linux. But instead of testing Linux
as a black box, **rtla** leverages kernel tracing capabilities to provide
precise information about the properties and root causes of unexpected
results.

COMMANDS
========
**hwnoise**

        Detect and quantify hardware-related noise.

**osnoise**

        Gives information about the operating system noise (osnoise).

**timerlat**

        Measures the IRQ and thread timer latency.

OPTIONS
=======
**-h**, **--help**

        Display the help text.

For other options, see the man page for the corresponding command.

Annotation

• Atlas domain: Support Tooling And Documentation / Documentation.
• Implementation status: atlas-only.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
