libie_fwlog_set(9)

💖 libie_fwlog_set(9) — it's giving "Kernel API Manual" energy 💖

okay bestie, welcome to libie_fwlog_set(9), straight out of the Kernel API Manual — yes that's the actual manual name, no cap, we're in the big leagues now ✨

---

🌸 NAME 🌸

libie_fwlog_set — the one that sets the firmware logging settings. iconic behavior, honestly.

---

🦋 SYNOPSIS 🦋

int libie_fwlog_set (struct libie_fwlog *fwlog , struct libie_fwlog_cfg
*cfg );

literally just two pointers and an int coming back at you. main character signature fr fr 💅

---

🎀 ARGUMENTS 🎀

• fwlog — pointer to the fwlog structure. your little handle to the whole situation 🫶
• cfg — the config used to set firmware logging. this is the actual vibe you're pushing in.

---

✨ DESCRIPTION ✨

so here's the tea 🍓 — this function should be called whenever the driver needs to set the firmware logging configuration. that's it, that's the whole job. lowkey simple, highkey important.

and when can you call it? whenever, bestie:

• on initialization
• on reset
• or during runtime

all valid, all slay 🔥

⚠️ okay pay attention here because this is the part people miss: if the PF wishes to receive FW logging then it must register via libie_fwlog_register. and the cute little footnote? libie_fwlog_register does not need to be called for init. like, at all. don't do it. ngl that one trips people up 😭
