💅 ppc440spe_desc_init_null_xor — Kernel API Manual ✨

okay bestie, welcome to the Kernel API Manual entry for ppc440spe_de...nit_null_xor(9) — yes the title is literally truncated with ... like that, that's not me being lazy, that's the header, periodt. 🎀

This page is all about one tiny little function that sets up a descriptor for a NULL XOR pseudo operation. It's giving "background character who does exactly one job and does it flawlessly", and honestly? We respect her. 💜

🌸 NAME 🌸

ppc440spe_desc_init_null_xor — initializes the descriptor for a NULL XOR pseudo operation. That's it, that's the whole vibe check. 🦋

✨ SYNOPSIS ✨

void ppc440spe_desc_init_null_xor (struct ppc440spe_adma_desc_slot *desc
);

like look at her. one parameter. no return value. lowkey iconic. 👑

🎀 ARGUMENTS 🎀

  • desc — ngl bestie, the source docs just say -- undescribed -- and leave it at that. no cap, that's literally the whole description we got. 🙈 So: it's the struct ppc440spe_adma_desc_slot * and the docs are not telling us anything more. we're on our own out here. 💀

🦋 SEE ALSO 🦋

first up, the actual source file where the magic lives:

  • Kernel file ./drivers/dma/ppc4xx/adma.c

and now the entire friend group, in order, no one left out, everyone invited to the group chat 😭💖:

like, that's sixty-nine cross-references. sixty-nine. she knows everyone at this party and she's not sorry about it. 🫶

and that's the whole page, bestie!! no bugs listed, no warnings, no exit statuses — just one descriptor init and a truly enormous friend list. slay. 💅✨

this little love letter lives at ./drivers/dma/ppc4xx in the Kernel API Manual, dated October 2026 — so mark your calendars, mwah, bye 🍓🧚💖
