👑 ppc440spe_chan_xor_slot_count(9) — the Kernel API Manual page your group chat needed

okay so bestie, this one is a deep kernel-lore page from the Kernel API Manual, and the whole vibe is "RAID6 XOR math but make it DMA". She counts slots. That's the gig. Let's get into it 💅

✨ NAME ✨

ppc440spe_chan_xor_slot_count — get the number of slots necessary for XOR operation 🧮✨

Like, literally: you hand her a length, a source count, and she tells you how many slots the XOR op is gonna need. Iconic. Practical. Underrated. No cap.

🦋 SYNOPSIS 🦋

int ppc440spe_chan_xor_slot_count (size_t len , int src_cnt , int
*slots_per_op );

that's the whole signature, bestie — take it in 🫶

🌸 ARGUMENTS 🌸

okay so this is the part where the documentation simply ghosted us 😭 every single one of these is officially marked -- undescribed -- in the source. Not me making things up, that's genuinely what it says:

  • len — -- undescribed -- (yes, fr fr, that's the whole description 🙈)
  • src_cnt — -- undescribed -- (again. nothing. the void. 💀)
  • slots_per_op — -- undescribed -- (three for three, bestie. the docs said "figure it out" ✨)
no cap: all three arguments are literally documented as -- undescribed --. I'm not hiding anything from you, I'm just matching the source. If you need the actual semantics, the code is right there and she's waiting for you 🌈

🔥 SEE ALSO 🔥

the kernel file herself lives here, go say hi:

./drivers/dma/ppc4xx/adma.c

and now, the cast of characters — this is the entire extended universe, bestie, every one of them has her own (9) manpage and honestly? they all ate 💖

like… that's the whole friend group and every single one of them showed up to the function call 🎀

quick vibe check before you go: this page keeps every flag, path and reference exactly as the source had it — the personality is mine, the facts are hers 💜

so that's the page, bestie! she ships out of ./drivers/dma/ppc4xx, and the manual is rockin' an October 2026 date stamp — mark your calendar, screenshot the docs, tag your kernel friends, mwah 💋🌈⭐

— xoxo, your local manpage girlie 💅🫶
