💅 ppc440spe_adma_prep_dma_pq(9) 💅

okay so bestie, welcome to the ppc440spe_adma_prep_dma_pq(9) page from the Kernel API Manual. The vibe is prepare CDB (group) for a GF-XOR operation, and honestly that name section ate. 💖

✨ NAME ✨

ppc440spe_adma_prep_dma_pq — prepare CDB (group) for a GF-XOR operation.

That's the whole NAME moment, bestie: it prepares a CDB (group) for a GF-XOR operation. No cap, that's the entire tea. 🫖

🦋 SYNOPSIS 🦋

The signature is literally this, character for character, so don't let anyone "fix" it on you:

struct dma_async_tx_descriptor * ppc440spe_adma_prep_dma_pq (struct
dma_chan *chan , dma_addr_t *dst , dma_addr_t *src , unsigned int
src_cnt , const unsigned char *scf , size_t len , unsigned long flags );

🎀 ARGUMENTS 🎀

The ARGUMENTS section is giving mystery era 😭 — every single one of these is marked -- undescribed -- in the page, so I'm not gonna invent lore. Here's the roll call so nobody ghosts us:

  • chan — -- undescribed -- (mystery main character energy 🙈).
  • dst — -- undescribed -- (the page said nothing, bestie).
  • src — -- undescribed -- (lowkey iconic for saying absolutely nothing).
  • src_cnt — -- undescribed -- (no crumbs).
  • scf — -- undescribed -- (we stay guessing).
  • len — -- undescribed -- (not me making up a description, periodt).
  • flags — -- undescribed -- (the mystery continues 💀).
