STRUCT ATH_OPS(9)

💅 struct ath_ops(9) 💅

okay bestie, welcome to the Kernel API Manual — this is the struct ath_ops page and it's literally the plug for register read/write operations. yes we're doing kernel plumbing today and yes you're gonna slay it 🫶

---

✨ NAME ✨

struct ath_ops — Register read/write operations. that's the whole vibe. register reads, register writes, that's her 👑

---

🌸 SYNOPSIS 🌸

here's the struct in all her glory, copy it exactly, do not freestyle:

struct ath_ops {
    unsigned int (*read)(void *, u32 reg_offset);
    void (*multi_read)(void *, u32 *addr, u32 *val, u16 count);
    void (*write)(void *, u32 val, u32 reg_offset);
    void (*enable_write_buffer)(void *);
    void (*write_flush) (void *);
    u32 (*rmw)(void *, u32 reg_offset, u32 set, u32 clr);
    void (*enable_rmw_buffer)(void *);
    void (*rmw_flush) (void *);
 };

like… she's just a little bundle of function pointers and honestly? iconic 🎀

💖 Members 💖

the manpage spells out these five for us, so let's go (iykyk):

• read — Register read. you want a register? she reads you a register. one function pointer, zero drama ✨
• multi_read — Multiple register read. it's giving "I'm not doing these one at a time" energy — this is the plural version, fr fr 🌈
• write — Register write. you hand her val and reg_offset, she writes it out. no cap 💅
• enable_write_buffer — Enable multiple register writes. turn the buffering ON so the writes can pile up cutely instead of going out one by one 🦋
• write_flush — flush buffered register writes and disable buffering. okay so this one is the main character moment: she flushes whatever's buffered AND turns buffering back off. both. at once. obsessed 💀

heads up bestie — the struct up top also carries rmw, enable_rmw_buffer and rmw_flush, but this page's Members list only spells out the five above. keeping it exactly as written, not gonna invent lore 🙈
