Welcome message and DL Server - Daniel Bristot de Oliveira
Description:
Explore the concept of DL server, a method allowing SCHED_DEADLINE to schedule an entire scheduler, in this Linux Plumbers Conference talk. Dive into its multiple applications, including scheduling the CFS scheduler to prevent SCHED_FIFO starvation. Examine the base case presented by peterz and the challenges it raised, such as priority inversion between CFS and FIFO tasks. Learn about recent progress with deferrable servers, which delay server activation. Engage in a discussion on crucial implementation aspects, including the deferrable server concept, interface design, and potential future expansions. Gain insights into this important scheduler community topic and its implications for Linux system performance.
