The Status of the Preempt-RT Patch

on YouTube ↗38m

" summary

An update on the Preempt-RT real-time Linux patchset explains that RT-queue backports are being merged into mainline kernel releases and many temporary patches will vanish once kernels advance. It describes concrete fixes already delivered (scheduler and IRQ threading cleanups, FUTEX fixes), lists a short remaining bug backlog, and outlines the workflow used: backporting, CI testing on embedded boards, and submitting merge requests upstream to reduce standalone patches and maintenance overhead.
