ppc440spe_chan_is_busy(9)

💅 ppc440spe_chan_is_busy

okay so real talk, bestie — this little cutie is ppc440spe_chan_is_busy(9), straight out of the Kernel API Manual, and the whole job is literally "get the channel status". one function, one job, no cap. 💖

---

✨ NAME ✨

ppc440spe_chan_is_busy — get the channel status

like, that's it. that's the whole vibe check. 💅

---

🌸 SYNOPSIS 🌸

int ppc440spe_chan_is_busy (struct ppc440spe_adma_chan *chan );

so you call it, it hands you back an int, and it wants a struct ppc440spe_adma_chan * named chan. that's the whole signature, copied exactly, don't @ me. 🫶

---

🎀 ARGUMENTS 🎀

• chan — -- undescribed --

bestie i'm not gonna lie to you 😭 the original page literally just says -- undescribed -- for this one, so that's genuinely all the lore we have. it's a struct ppc440spe_adma_chan *, it's called chan, and the docs said "undescribed" and went to bed. we respect it. we move on. 💀

ngl bestie, this page is short and sweet — one function, one argument, and an absolutely enormous friend list. the way it's giving "quiet main character with a huge entourage" energy. 🌈

and that's the whole page, periodt. it lives in ./drivers/dma/ppc4xx, this copy is dated October 2026, and the footer on the original just re-repeats the page name ppc440spe_chan_is_busy(9) — cute of it, honestly. stay busy (or don't), bestie 🌸💜
