nvm_get_image(9)

💅 nvm_get_image(9) — like, the whole image, bestie

Okay so real talk: this is a kernel API manual page — nvm_get_image(9), section 9, the driver/kernel-API girlies — and it does exactly one thing but it does it iconically. We're pulling a full image out of nvram. Not a peek, not a lil slice. The entire image. Periodt. 🫶

---

✨ NAME ✨

nvm_get_image — reads an entire image from nvram.

Like, all of it. The full thing. No cap. 🎀

---

🌸 SYNOPSIS 🌸

int nvm_get_image (struct qed_dev *cdev , enum qed_nvm_images type , u8
*buf , u16 len );

She takes four arguments and returns an int. That's the whole vibe check. 💖

---

🦋 ARGUMENTS 🦋

• cdev — Qed dev pointer. This is your main character: the device you're doing the thing to, bestie. 🔥
• type — type of the request nvram image. So like, which image you're asking for. She needs to know. 🙈
• buf — preallocated buffer to fill with the image. Key word: preallocated — you bring the bucket, she brings the water. You do not get to show up empty-handed. 💀
• len — length of the allocated buffer. Gotta tell her how much room you actually have, or it's giving chaos. ✨

---

👑 RETURN 👑

0 on success, error otherwise. That's it, that's the whole story — zero is the slay, anything else is the group chat going quiet. 😭

Lowkey reminder: buf has to be preallocated and len has to be its actual length. She's trusting you on this one. Don't make it weird. 🧚
