A pull request [1] has been opened in the OpenWrt core repository to introduce the PREEMPT_RT kernel configuration option for x86_64, arm64, and RISC-V architectures.
Enabling PREEMPT_RT makes it essential to analyze and characterize the kernel’s real-time performance. To support this, this pull request integrates existing tools for real-time behavior analysis into OpenWrt.
Some tools require the new tracers introduced in [1].
It can also be applied safely on openwrt-25.12 branch
