STRUCT RVT_OPERATION_PARAMS(9)

💖 struct rvt_operation_params(9) 💖

Okay bestie, this page is from the Kernel API Manual, and it's all about the op table entry struct. Short, sweet, iconic. 🎀

🌸 NAME 🌸

struct rvt_operation_params — op table entry

✨ SYNOPSIS ✨

struct rvt_operation_params {
    size_t length;
    u32 qpt_support;
    u32 flags;
};

👑 Members 👑

• length — the length to copy into the swqe entry. Literally that. 💅
• qpt_support — a bit mask indicating QP type support. Slay.
• flags — RVT_OPERATION flags (see above 👀).

🦋 Description 🦋

Okay so the whole point: this supports table driven post send so that the driver can have differing — and potentially different — sets of operations. That's the tea. 🍵✨
