uncache_firmware(9)

💅 uncache_firmware(9) — bestie's guide to yeeting one cached firmware image

okay so this is a page from the Kernel API Manual (uncache_firmware(9)), and honestly? it's a short one, but it's iconic. let's get into it ✨

---

🌸 NAME 🌸

uncache_firmware — remove one cached firmware image. literally just one. not all of them. one. 🎀

---

🦋 SYNOPSIS 🦋

int uncache_firmware (const char *fw_name );

that's it. that's the whole vibe. one function, one argument, one return value. main character energy fr fr 💖

---

✨ ARGUMENTS ✨

• fw_name — the firmware image name. like, the name of the firmware image. that's the whole thing. 🫶

---

🔥 DESCRIPTION 🔥

Uncache one firmware image which has been cached successfully before. so like, it has to have actually been cached first, bestie — no cap, that's the prerequisite. 🙈

Return 0 if the firmware cache has been removed successfully. Return !0 otherwise. so zero means slay, not-zero means something went sideways. 👑

lowkey important: it's 0 for success and !0 for not-success. don't flip those or you're gonna have a bad time 💀
