pldm_check_fw_space(9)

💖 pldm_check_fw_space — the vibe check for your firmware image ✨

Okay so bestie, real talk: this is a kernel API manual page for pldm_check_fw_space(9), and it's lowkey one of the most relatable functions in ./lib/pldmfw because all it does is ask "girl, do you even have room for this?" 🎀 It's the bouncer at the club door of your firmware blob, and honestly? Iconic.

🌸 NAME 🌸

pldm_check_fw_space — Verify that the firmware image has space left 💅

---

✨ SYNOPSIS ✨

int pldm_check_fw_space (struct pldmfw_priv *data , size_t offset ,
       size_t length );

---

🫶 ARGUMENTS 🫶

• data — pointer to private data 🌈 (the main character struct)
• offset — offset to start from 🦋 (where we're peeking)
• length — length to check for 💜 (how many bytes we're hoping for)

---

💖 DESCRIPTION 💖

So basically, this function Verifies that the firmware data can hold a chunk of bytes with the specified offset and length. That's it. That's the whole job. And ngl, it does it perfectly. 🧚

Like, before anything gets too comfy, pldm_check_fw_space looks at the firmware data and goes "okay but is there actually space for this chunk of bytes at this offset with this length?" — and if the math doesn't math, it says so. Periodt. ⭐

---

🔥 RETURN 🔥

• zero on success — slay, we have room, let's go 💅
• -EFAULT if the image does not have enough space left to fit the expected length — not enough room bestie, no cap 😭
