STRUCT IDPF_REG_OPS(9)

💖 struct idpf_reg_ops(9) 💖

okay so bestie, welcome to the struct idpf_reg_ops(9) page from the Kernel API Manual — this is the glow-up doc for a struct full of device specific register operation function pointers. it's giving "the plug board for register poking" and honestly? iconic. 🎀

---

✨ NAME ✨

struct idpf_reg_ops — device specific register operation function pointers. literally the little black book of "who do i call to touch which register" 👑

---

🌸 SYNOPSIS 🌸

struct idpf_reg_ops {
    void (*ctlq_reg_init)(struct libie_mmio_info *mmio, struct
libie_ctlq_create_info *cctlq_info);
    int (*intr_reg_init)(struct idpf_vport *vport, struct
idpf_q_vec_rsrc *rsrc);
    void (*mb_intr_reg_init)(struct idpf_adapter *adapter);
    void (*reset_reg_init)(struct idpf_adapter *adapter);
    void (*trigger_reset)(struct idpf_adapter *adapter, enum idpf_flags
trig_cause);
    void (*ptp_reg_init)(const struct idpf_adapter *adapter);
 };

💅 Members 💅

• ctlq_reg_init — mailbox control queue register initialization. the control-queue setup girlie 🦋
• intr_reg_init — traffic interrupt register initialization. yes, the traffic interrupts, she's busy 🔥
• mb_intr_reg_init — mailbox interrupt register initialization. mailbox but make it interrupt ✨
• reset_reg_init — reset register initialization. setting the stage for a fresh start 🌸
• trigger_reset — trigger a reset to occur. no cap, this one actually makes the reset happen 💀
• ptp_reg_init — PTP register initialization. precision time protocol gets her own dedicated pointer, as she deserves 👑

bestie reminder: those function pointers are device specific — which is the whole point, so don't go assuming one device's register dance works on another. iykyk 🧚
