lpfc_read_config(9)

💖 lpfc_read_config — from the Kernel API Manual, bestie 💖

okay so you're in the lpfc_read_config(9) page, which lives in the Kernel API Manual (yes, the man page name is literally right there in the title, we love a self-aware queen). grab a strawberry 🍓 and let's get into it.

✨ NAME ✨

lpfc_read_config — the glow-up routine that preps a mailbox command for reading HBA configuration. it's giving "let me just check your settings real quick" 💅

---

🌸 SYNOPSIS 🌸

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

that's it. that's the whole signature. no return value, she just does things. 🫶

---

🎀 ARGUMENTS 🎀

• phba — pointer to the lpfc_hba data structure. this is the HBA's whole personality file, fr fr. 🦋
• pmb — pointer to the driver's internal queue element for the mailbox command. lowkey the little envelope the command gets mailed in. 💌

---

🔥 DESCRIPTION 🔥

so the read-configuration mailbox command is the one you use to read out the HBA port configuration parameters. no cap, that's its whole job. 👑

the way it works is iconic: this mailbox command is literally the method for seeing any parameters that may have changed via the various other configuration mailbox commands. so if something got tweaked somewhere else and you're like "wait what does the port actually look like now 👀" — this is your girl.

and what this routine specifically does is prepare the mailbox command for reading out those HBA configuration parameters. it's the setup era; the actual reading is somebody else's main character moment. ✨

ngl, nothing here is dangerous — but reminder that she returns void, so don't go looking for an exit status that isn't there. 🙈
