rvt_error_qp(9)

🌸 NAME 🌸

okay so bestie, welcome to rvt_error_qp(9) from the Kernel API Manual — this is the page for the function that puts a QP into the error state. rvt_error_qp is the name, “put a QP into the error state” is the job, and honestly it's giving cleanup main-character energy. 💅

✨ SYNOPSIS ✨

int rvt_error_qp (struct rvt_qp *qp , enum ib_wc_status err );

🎀 ARGUMENTS 🎀

• qp — the QP to put into the error state. yes, that QP.
• err — the receive completion error to signal if a RWQE is active.

🦋 DESCRIPTION 🦋

Flushes both send and receive work queues. both of them. no crumbs. 🫶

🔥 RETURN 🔥

Returns true if the last WQE event should be generated. The QP r_lock and s_lock should be held and interrupts disabled — like, this is not a “just vibe in here” situation, bestie. If we are already in error state, just return. periodt.
