STRUCT DMA_CHAN_TBL_ENT(9)

✨ struct dma_chan_tbl_ent(9) ✨

okay so this is a page straight out of the Kernel API Manual, bestie, and it's about struct dma_chan_tbl_ent — literally the tiny lil struct that tracks channel allocations per core/operation. it's giving very much "small struct, big responsibilities" energy 💅

---

🌸 NAME 🌸

struct dma_chan_tbl_ent — tracks channel allocations per core/operation 🎀

like, that's its whole personality. it keeps tabs on who's using which channel, per core and per operation. lowkey iconic.

🦋 SYNOPSIS 🦋

struct dma_chan_tbl_ent {
    struct dma_chan *chan;
 };

that's it. that's the struct. one member. she's minimal, she's clean, she's a whole vibe ✨ (and yes, bestie, you clocked that little space before the closing brace — keeping it exactly as the page has it, no cap 🫶)

💖 Members 💖

• chan — the associated channel for this entry 🔥 like, this is the channel that belongs to this table entry. the main character of the struct, fr fr.
