[PATCH v2 0/1] Documentation: Add real-time kernel configuration guide

From: Ahmed S. Darwish

Date: Tue Apr 14 2026 - 13:43:02 EST


Hi,

There is a no "one size fits all" solution for configuring a PREEMPT_RT
kernel. Intorduce a PREEMPT_RT kernel configuration guide to better help
system developers and integrators.

Changelog v2
------------

Handle Rostedt remarks:

- Better reword certain paragraphs and statements
- Warn about enabling CONFIG_IRQSOFF_TRACER and CONFIG_PREEMPT_TRACER

Handle Wilcox remarks:

- Remove ToC comment + minor rewording

Changelog v1
------------

Thanks,
