ppc440spe_xor_set_link(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the Kernel API Manual — yes, that's the manual name, we're fancy here ✨ — and today's main character is ppc440spe_xor_set_link, a little function living its best life in the ppc4xx DMA driver. It sets a link address in an xor CB. That's the whole vibe. Short page, iconic function, let's go 🎀

✨ NAME ✨

ppc440spe_xor_set_link — set link address in xor CB 🦋

🌸 SYNOPSIS 🌸

void ppc440spe_xor_set_link (struct ppc440spe_adma_desc_slot *prev_desc
, struct ppc440spe_adma_desc_slot *next_desc );

literally returns void, no notes, no drama, no return value, she just does the thing and leaves 💅

💖 ARGUMENTS 💖

  • prev_desc — -- undescribed -- 🙈 ngl bestie, the docs did NOT come through here. No description, no lore, nothing. We respect the mystery.
  • next_desc — -- undescribed -- 😭 same situation, also undescribed. Two arguments, zero explanations, and honestly? That's just how the source rolls.
no cap, those -- undescribed -- bits are exactly what the manual says, so I'm not out here inventing backstory for them. we keep the facts, we just serve them with better energy 💀
