libie_fwlog_supported(9)

💅 libie_fwlog_supported — the "does the firmware even do FW logging" vibe check

Okay so real talk, bestie: this page is from the Kernel API Manual, and it's about libie_fwlog_supported, which is literally just the cached answer to the question "does this firmware support FW logging or not?" That's it. That's the whole gig. ✨

---

🌸 SYNOPSIS

bool libie_fwlog_supported (struct libie_fwlog *fwlog );

Returns a bool, takes a pointer to a struct libie_fwlog, and yes she's that simple. 🎀

---

🦋 ARGUMENTS

• fwlog — pointer to the fwlog structure. Just hand her the struct, she knows what to do. 🫶

---

💖 DESCRIPTION

So the way this works: this function returns the cached value of whether the firmware supports FW logging or not. No fresh probing, no dramatic re-check, just the stored answer, bestie. 💅

🚨 Important caveat, and I mean it: this will always return false if you call it before libie_init_hw. Always. Like, it's not being shady, it just doesn't know yet. So it must be called after libie_init_hw. No cap. 😭
