STRUCT TXX9DMAC_PLATFORM_DATA(9)

💖 struct txx9dmac_platform_data(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this one's a lil struct page and it's honestly short but she's got range. let's get into it 🫶

---

🌸 NAME 🌸

struct txx9dmac_platform_data — literally just the controller configuration parameters, that's her whole job 💅

---

✨ SYNOPSIS ✨

here's the shape of her, exactly as she is, no cap:

struct txx9dmac_platform_data {
    int memcpy_chan;
    bool have_64bit_regs;
};

---

🎀 Members 🎀

• memcpy_chan — this is the channel that gets used for DMA_MEMCPY. that's the one. the memcpy channel. iconic behavior honestly 🌈
• have_64bit_regs — a bool that says whether the DMAC has 64 bit registers. yes/no, true/false, slay/not slay, that's the whole vibe check 💀

ngl bestie, this page is basically two fields and a dream, but every main character needs her supporting cast 😭 go read the channel platform data and the slave struct and it'll all click fr fr 💜

mwah 💋 that's the whole page — sourcing from ./arch/mips/include/asm/txx9, dated October 2026, and that's on periodt. 🎀⭐
