💖 pldm_parse_header(9) 💖

okay bestie, welcome to the Kernel API Manual page for pldm_parse_header — this is the little function that does the PLDM header vibe check before anything else gets to pop off ✨

🧚 SYNOPSIS 🧚

int pldm_parse_header (struct pldmfw_priv *data );

🎀 ARGUMENTS 🎀

• data — pointer to private data. that’s the whole argument, bestie 🫶

✨ DESCRIPTION ✨

So basically, pldm_parse_header performs the initial basic verification of the PLDM image, up to the first firmware record. it’s giving “first look before the real work starts” energy 💅

This includes the following checks and extractions:

• Verify that the UUID at the start of the header matches the expected value as defined in the DSP0267 PLDM specification 🦋
• Check that the revision is 0x01 ⭐
• Extract the total header_size and verify that the image is large enough to contain at least the length of this header 🎀
• Extract the size of the component bitmap length 🌸
• Extract a pointer to the start of the record area 💜

🌈 RETURN 🌈

zero on success, or a negative error code on failure. no in-between, no cap 😭
