lpfc_reg_rpi(9)

✨ NAME ✨

lpfc_reg_rpi — Prepare a mailbox command for registering remote login.

Okay so bestie, welcome to the lpfc_reg_rpi(9) page from the Kernel API Manual 💖. This is the little helper that gets a mailbox command ready so a remote login can be registered. Slay.

---

🌸 SYNOPSIS 🌸

int lpfc_reg_rpi (struct lpfc_hba *phba , uint16_t vpi , uint32_t did ,
uint8_t *param , LPFC_MBOXQ_t *pmb , uint16_t rpi );

---

🎀 ARGUMENTS 🎀

• phba — pointer to lpfc hba data structure. The main character HBA struct, basically.
• vpi — virtual N_Port identifier.
• did — remote port identifier.
• param — pointer to memory holding the server parameters.
• pmb — pointer to the driver internal queue element for mailbox command.
• rpi — the rpi to use in the registration (usually only used for SLI4).

---

🦋 DESCRIPTION 🦋

The registration login mailbox command is used to register an N_Port or F_Port login. This registration allows the HBA to cache the remote N_Port service parameters internally and thereby make the appropriate FC-2 decisions. The remote port service parameters are handed off by the driver to the HBA using a descriptor entry that directly identifies a buffer in host memory. In exchange, the HBA returns an RPI identifier. Literally the whole point, no cap 🔥.

This routine prepares the mailbox command for registering remote port login. The function allocates DMA buffer for passing the service parameters to the HBA with the mailbox command.

Return codes:

• 0 — Success
• 1 — DMA memory allocation failed

Bestie, keep those return codes in mind — 0 is the cute one, 1 means the DMA memory allocation said “not today.” 😭
