πŸ’… sys_rseq_slice_yield(9) πŸ’…

okay bestie, this is the sys_rseq_slice_yield(9) page from the Kernel API Manual, and it’s giving β€œyield the CPU politely” energy. no cap, the facts below are exactly the facts. 🫢

✨ NAME ✨

sys_rseq_slice_yield β€” yield the current processor side effect free if a task granted with a time slice extension is done with the critical work before being forced out. πŸ’…

🌸 SYNOPSIS 🌸

long sys_rseq_slice_yield (void );

πŸŽ€ ARGUMENTS πŸŽ€

  • void β€” no arguments. literally none. not a single one. πŸ’€

⭐ RETURN ⭐

  • 1 β€” the task successfully yielded the CPU within the granted slice. slay. βœ…
  • 0 β€” the slice extension was either never granted, or it was revoked by:
    • going over the granted extension,
    • using a syscall other than this one,
    • or being scheduled out earlier due to a subsequent interrupt. 😭

πŸ¦‹ DESCRIPTION πŸ¦‹

this syscall does not schedule, because the syscall entry work immediately relinquishes the CPU and schedules if required. that’s the whole vibe: the entry work handles it, not the syscall itself. ✨
