💅 lpfc_unreg_login(9) — the Kernel API Manual glow-up ✨

okay bestie, so this page lives in the Kernel API Manual section 9 (that's the kernel API page number, iykyk) and it's all about lpfc_unreg_login — the function that preps a mailbox command to unregister a remote login. let's get into it 🎀

🌸 NAME 🌸

lpfc_unreg_login — prepare a mailbox command for unregistering remote login

🦋 SYNOPSIS 🦋

void lpfc_unreg_login (struct lpfc_hba *phba , uint16_t vpi , uint32_t
rpi , LPFC_MBOXQ_t * pmb );

like, that's the whole signature, keep it exactly as-is fr fr 🫶

💖 ARGUMENTS 💖

  • phba — pointer to lpfc hba data structure. the main character struct 💅
  • vpi — virtual N_Port identifier.
  • rpi — remote port identifier
  • pmb — pointer to the driver internal queue element for mailbox command.

✨ DESCRIPTION ✨

the unregistration login mailbox command is used to unregister an N_Port or F_Port login. this command frees an RPI context in the HBA. it has the effect of performing an implicit N_Port/F_Port logout. (yes, implicit — it just happens, no cap 😭)

this routine prepares the mailbox command for unregistering remote port login.

🚨 for SLI4 ports, the rpi passed to this function must be the physical rpi value — not the logical index. like, do not pass the logical one, okay bestie? that's the vibe check and it will not slay if you get it wrong 💀
