lpfc_read_nv(9)

okay bestie, welcome to lpfc_read_nv(9) from the Kernel API Manual — this is the page where we prep a mailbox command for reading the HBA's NVRAM param, and honestly it's giving quiet-but-iconic kernel energy 💅

🌸 NAME 🌸

lpfc_read_nv — Prepare a mailbox command for reading HBA's NVRAM param. That's the whole vibe: prep the mailbox command, read the NVRAM param, slay. ✨

🎀 SYNOPSIS 🎀

void lpfc_read_nv (struct lpfc_hba * phba , LPFC_MBOXQ_t * pmb );

🦋 ARGUMENTS 🦋

• phba — pointer to lpfc hba data structure. Your HBA bestie, basically 🫶
• pmb — pointer to the driver internal queue element for mailbox command. The little queue-element main character for this mailbox moment 💖

💖 DESCRIPTION 💖

Okay so the read NVRAM mailbox command returns the HBA's non-volatile parameters that are used as defaults when the Fibre Channel link is brought on-line. Periodt. 🔥

This routine prepares the mailbox command for reading information stored in the HBA's NVRAM. Specifically, the HBA's WWNN and WWPN — yes, those iconic IDs, iykyk 👑✨
