💅 scx_bpf_task_set_dsq_vtime(9) ✨

okay bestie, welcome to the Kernel API Manual — this is the page for scx_bpf_task_set_dsq_vtime, and it's genuinely not that deep, but the details matter so let's go 🫶

🌸 NAME 🌸

scx_bpf_task_set_dsq_vtime — set a task's virtual time for DSQ ordering, no cap 💫

✨ SYNOPSIS ✨

__bpf_kfunc bool scx_bpf_task_set_dsq_vtime (struct task_struct *p , u64
vtime , const struct bpf_prog_aux *aux );

🎀 ARGUMENTS 🎀

  • p — the task of interest. yes, that task. the main character 👑
  • vtime — the virtual time you wanna set it to. that's the number, bestie 🧮
  • aux — the implicit BPF argument that gives you access to bpf_prog_aux, and it's hidden from BPF progs 🙈 so like… it's there, you just don't get to see it. vibes.

🦋 DESCRIPTION 🦋

So what does it actually do? It sets p's virtual time to vtime. That's it. That's the whole thing 💅

It returns true on success, and false if the calling scheduler doesn't have authority over p — like, it's not your task to mess with, stay in your lane literally 😭
