ppc440spe_adma_tx_status(9)

💅 ppc440spe_adma_tx_status(9) — like, the Kernel API Manual page, bestie ✨

okay so real talk, this is a page from the Kernel API Manual and it's about polling how an ADMA transaction is doing. yes, polling. like refreshing your feed but for hardware DMA descriptors. iykyk 🦋

🌸 NAME 🌸

ppc440spe_adma_tx_status — poll the status of an ADMA transaction. that's it, that's the vibe check 👑

---

✨ SYNOPSIS ✨

enum dma_status ppc440spe_adma_tx_status (struct dma_chan *chan ,
dma_cookie_t cookie , struct dma_tx_state *txstate );

look at her. iconic signature. no cap 💅

---

🎀 ARGUMENTS 🎀

• chan — the ADMA channel handle 🫶 this is your main character, the channel you're asking about
• cookie — the ADMA transaction identifier 🍓 like a little receipt number for the transaction, so the channel knows which one you mean
• txstate — a holder for the current state of the channel 💖 you pass this in and it gets to hold the state, that's literally its job

ngl these three are the whole thing. short page, but she ate 🔥
