STRUCT IDPF_INTR_REG(9)

💅 struct idpf_intr_reg(9)

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a little struct from the kernel's internal docs, and honestly? she's giving "register layout for interrupt stuff" and we're obsessed 💖

---

🌸 NAME 🌸

struct idpf_intr_reg — no cap, that's literally the whole name field. The OG page leaves the description blank, so we're not gonna invent one 🫶 (we just respect the silence).

✨ SYNOPSIS ✨

here's the whole vibe, copied exactly, do not touch, do not "fix" her 🎀

struct idpf_intr_reg {
    void __iomem *dyn_ctl;
    u32 dyn_ctl_intena_m;
    u32 dyn_ctl_intena_msk_m;
    u32 dyn_ctl_itridx_s;
    u32 dyn_ctl_itridx_m;
    u32 dyn_ctl_intrvl_s;
    u32 dyn_ctl_wb_on_itr_m;
    u32 dyn_ctl_sw_itridx_ena_m;
    u32 dyn_ctl_swint_trig_m;
    void __iomem *rx_itr;
    void __iomem *tx_itr;
    void __iomem *icr_ena;
    u32 icr_ena_ctlq_m;
};

🎀 Members 🎀

time for the member-by-member vibe check, every single one, no skipping 🔥

• dyn_ctl — the dynamic control interrupt register 💫
• dyn_ctl_intena_m — mask for the dyn_ctl interrupt enable ✨
• dyn_ctl_intena_msk_m — mask for the dyn_ctl interrupt enable mask (yes, a mask for the mask, she contains multitudes) 💅
• dyn_ctl_itridx_s — register bit offset for the ITR index 🌸
• dyn_ctl_itridx_m — mask for the ITR index 🦋
• dyn_ctl_intrvl_s — register bit offset for the ITR interval ⭐
• dyn_ctl_wb_on_itr_m — mask for the WB on ITR feature 👑
• dyn_ctl_sw_itridx_ena_m — mask for the SW ITR index 🌈
• dyn_ctl_swint_trig_m — mask for the dyn_ctl SW triggered interrupt enable 💜
• rx_itr — the RX ITR register 🍓
• tx_itr — the TX ITR register 🧚
• icr_ena — interrupt cause register offset 😭
• icr_ena_ctlq_m — mask for ICR (short and sweet, we love her) 🎀

okay that's the whole page, bestie — nothing hidden, nothing dropped, every flag and field accounted for 💖

and that's a wrap, iykyk 🫶 this lil page lives in ./drivers/net/ethernet/intel/idpf, dated October 2026, and she's filed under struct idpf_intr_reg(9) in the Kernel API Manual — iconic, periodt 💅✨
