pldm_parse_image(9)

💖 pldm_parse_image — the kernel API manual, but make it make sense 💖

okay so bestie, we're in the pldm_parse_image(9) page, section 9 of the Kernel API Manual, and this one is genuinely lowkey iconic. it's a PLDM image parser. let's get into it 🫶

---

✨ NAME ✨

pldm_parse_image — parse and extract details from a PLDM image, fr fr 💅

---

🎀 SYNOPSIS 🎀

int pldm_parse_image (struct pldmfw_priv *data );

that's the whole signature. it takes one thing. it returns an int. we love a clean little function, no cap.

---

🌸 ARGUMENTS 🌸

• data — pointer to private data. that's it, that's the whole argument list. main character has exactly one parameter and we respect it 👑

---

🦋 DESCRIPTION 🦋

so what does she actually do? two things, and they're both important:

1. Verify that the firmware file contains valid data for a PLDM firmware file. yes, verify. as in check it's not nonsense before anything else happens. this is not optional energy, this is a vibe check on your firmware 🔥
2. Extract useful pointers and data from the firmware file and store them in the data structure. so after she's done, your data struct is all filled in with the good stuff ✨

the PLDM firmware file format is defined in DMTF DSP0267 1.0.0. write that down, iykyk. it's the whole spec, it's not vibes-based, it's a real document.

⚠️ bestie, listen to me: care should be taken to use get_unaligned_le* when accessing data from the pointers in data. this is not a drill. unaligned access is real and she will bite you. use the get_unaligned_le* helpers. periodt 💀

---

💜 RETURN 💜

• zero on success
• a negative error code on failure

that's it. no fancy enums, no positive success values. zero = slay, negative = something went wrong and you should go look at the error code 😭
