STRUCT DIM_IRQ_MODER(9)

👑 struct dim_irq_moder(9) — the Kernel API Manual glow-up ✨

okay so bestie, welcome to the struct dim_irq_moder page from the Kernel API Manual 💅 this one's a struct, not a function, so think of it less as "a thing you call" and more as "the little clipboard where we write down everything we know about irq moderation" 🎀

---

✨ NAME ✨

struct dim_irq_moder — the structure for irq moderation information. literally its whole job is to collect irq moderation related information together, iykyk 🫶

---

🌸 SYNOPSIS 🌸

struct dim_irq_moder {
    u8 profile_flags;
    u8 coal_flags;
    u8 dim_rx_mode;
    u8 dim_tx_mode;
    struct dim_cq_moder *rx_profile;
    struct dim_cq_moder *tx_profile;
    void (*rx_dim_work)(struct work_struct *work);
    void (*tx_dim_work)(struct work_struct *work);
 };

she's got four u8 fields up top, two struct dim_cq_moder * pointers in the middle, and two function pointers at the bottom, no cap 💖

🦋 Members 🦋

here's the member-by-member breakdown, bestie — every single one, nothing skipped:

• profile_flags — these are the DIM_PROFILE_* flags, living their best life 🌈
• coal_flags — the DIM_COALESCE_* flags, and note it's for Rx and Tx, both of them, together, iconic 🔥
• dim_rx_mode — Rx DIM period count mode: it's either CQE or EQE 👑
• dim_tx_mode — Tx DIM period count mode: again, CQE or EQE ⭐
• rx_profile — the DIM profile list for Rx 📋
• tx_profile — the DIM profile list for Tx 📋
• rx_dim_work — the Rx DIM worker, and it gets scheduled by net_dim 🧚
• tx_dim_work — the Tx DIM worker, also scheduled by net_dim 🧚

fr fr every one of those matters — if you're touching moderation profiles, this struct is where all the receipts live 💀
