💖 ipa_cmd_hdr_init_local_add (9) — Kernel API Manual, bestie edition 🎀

okay so first of all, yes, the title is a whole mouthful, but we're in the Kernel API Manual and we're gonna get through it together, i promise ✨

✨ NAME ✨

ipa_cmd_hdr_init_local_add — literally just "Add a header init command to a transaction", that's the whole vibe 💅

🌸 SYNOPSIS 🌸

void ipa_cmd_hdr_init_local_add (struct gsi_trans *trans, u32 offset,
                                 u16 size, dma_addr_t addr);

no cap, that's the whole signature 🫶

🦋 ARGUMENTS 🦋

  • trans — the GSI transaction, aka the main character this command is tagging along with 👑
  • offset — offset of header memory, but specifically in IPA local space (iykyk) 📍
  • size — how big the header memory is, keep it cute and keep it accurate 🎀
  • addr — the DMA address of the buffer we're writing from, yes from, not to 💖

⭐ DESCRIPTION ⭐

so what it actually does: it defines and fills the location in IPA memory to use for headers. that's it, that's the function, and honestly? iconic. it's giving "setup girlie" energy — quietly doing the important background work so everything else slays later 🔥

🌈 SEE ALSO 🌈
