Hi Roman, Scheduler BPF is a great idea. Thanks for the work. Scheduler BPF won’t be a small feature, I think we’d better give a summary of possible hooks it may add first. We must have a *basic rule* to control what it will tend to be to avoid adding BPF hooks here and there. I haven’t found a clear rule yet, but maybe we can learn it from netfilter, which has 5 basic hooks. Regarding the scheduler BPF hooks, some possible basic hooks may be: - Hook for Enqueue - Hook for Dequeue - Hook for Put Prev Task - Hook for Set Next Task > An example of an userspace part, which loads some simple hooks is available > here [3]. It's very simple, provided only to simplify playing with the provided > kernel patches. > You’d better add this userspace code into samples/bpf/. [Some error occurs in my mail client, so I resend it] -- Thanks Yafang
