[PATCH v4 0/1] Documentation: Add real-time kernel configuration guide
From: Ahmed S. Darwish
Date: Thu Jul 16 2026 - 15:57:36 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 v4
------------
Handle Sashiko review: Remove a no-longer-referenced link. Remove
CONFIG_WQ_SYS reference, which I thought it exists due to a quick
misunderstanding of core-api/workqueue.
Changelog v3
------------
CONFIG_EFI_DISABLE_RUNTIME: Mention that system integrators can now assign
the efi_runtime workqueue CPU affinity, then safely pin RT tasks on a
different CPU range.
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
------------
