💅 tid_rdma_schedule_tid_wakeup — Kernel API Manual ✨

okay so bestie, welcome to the group chat, this is the manual page for tid_rdma_schedule_tid_wakeup(9) and honestly? she's a little baddie with one job and one job only 🎀

---

🌸 NAME 🌸

tid_rdma_schedule_tid_wakeup — schedule wakeup for a qp 💤➡️🔔

---

✨ SYNOPSIS ✨

void tid_rdma_schedule_tid_wakeup (struct rvt_qp *qp );

like yes that's the whole signature, she's short and she knows it 🫶

---

🎀 ARGUMENTS 🎀

• qp — the qp. that's it. that's the argument. the qp in question, the main character of this function 🔥

---

💖 DESCRIPTION 💖

so what she does is trigger a schedule or a waiting qp in a deadlock safe manner. no cap, deadlock safety is the whole vibe here — she does NOT do chaos, she does controlled chaos 💅

the qp reference is held prior to this call via first_qp. so like, the ref is already yours before you even walk in the door, iykyk ✨

then here's the tea 👀 — if the qp trigger was already scheduled (!rval), the reference is dropped. otherwise, the resume or the destroy cancel will dispatch the reference. either way that ref gets handled, she never leaves it hanging, periodt 🧚

fr fr pay attention to which branch you're in — the ref gets dropped in one case and dispatched by resume/destroy cancel in the other. no leaks, no mess 💀
