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 ------------ https://lore.kernel.org/lkml/20260305205023.361530-1-darwi@linutronix.de Thanks, 8<----- Documentation/core-api/real-time/index.rst | 1 + .../real-time/kernel-configuration.rst | 313 ++++++++++++++++++ 2 files changed, 314 insertions(+) create mode 100644 Documentation/core-api/real-time/kernel-configuration.rst base-commit: 028ef9c96e96197026887c0f092424679298aae8 -- 2.53.0
