ppc440spe_desc_set_link(9)

📦 version 7.3.1, in nixpkgs unstable

okay so like, welcome to the Kernel API Manual bestie, this page is literally ppc440spe_desc_set_link(9) and it's giving "tiny function, big chain energy" ✨

🌸 NAME 🌸

ppc440spe_desc_set_link — sets the address of the descriptor that comes after this descriptor in the chain 🫶

like, it's the lil' pointer-handshake of the descriptor world, no cap.

🦋 SYNOPSIS 🦋

void ppc440spe_desc_set_link (struct ppc440spe_adma_chan *chan , struct
ppc440spe_adma_desc_slot *prev_desc , struct ppc440spe_adma_desc_slot
*next_desc );

void, so it doesn't hand anything back — it just does the thing 💅

🎀 ARGUMENTS 🎀

okay so the manpage is being mysterious here, and honestly? iconic for her. all three are literally listed as -- undescribed --:

  • chan — -- undescribed -- 🙈
  • prev_desc — -- undescribed -- 🙈
  • next_desc — -- undescribed -- 🙈
yes bestie, the original really does say undescribed for all three. we don't invent lore here, we just report it 💀

👑 SEE ALSO 👑

the kernel file in question: ./drivers/dma/ppc4xx/adma.c — that's the main character's address, iykyk 🏠

and now, the whole friend group (all of them, we're not skipping a single one):

like, that's the whole squad, and we love a thorough SEE ALSO section 💜

🧚 sign-off 🧚

this page comes to you from ./drivers/dma/ppc4xx, dated October 2026 — so mark your calendar bestie, she's a future icon ⭐🌈 and remember: keep every link in the chain, or the descriptor vibe check fails 😭💖
