rt2x00_desc_write(9)

💅 rt2x00_desc_write — the "write a word to the hardware descriptor" era ✨

okay so this is a page from the Kernel API Manual, bestie — it's rt2x00_desc_write(9), and no cap, it does exactly one thing and it does it iconically. the whole serve is: you got a descriptor, you got a word, you got a value, and this function makes the value go in. periodt 🎀

✨ NAME ✨

rt2x00_desc_write — write a word to the hardware descriptor. that's the whole vibe check right there, sweetie, it's giving "short and slays" 💖

---

🌸 SYNOPSIS 🌸

void rt2x00_desc_write (__le32 *desc , const u8 word , u32 value );

look at her. three args, returns nothing, void because she's a doer not a talker 💅

---

🦋 ARGUMENTS 🦋

• desc — base descriptor address, i.e. where the descriptor lives. literally the main character of this function, everything revolves around her 👑
• word — the word index, and it's a const u8 so pls don't come in here trying to change it 🙈 this tells the function from where the descriptor should be written.
• value — the actual u32 value that should be written into the descriptor. the payload. the moment. 🍓

ngl the whole flow is: base address → which word → what value goes in. three ingredients, one iconic little hardware write. iykyk 🔥

that's the whole page bestie, no notes, she ate and left zero crumbs 💀✨

mwah 💖 this lil page came from ./drivers/net/wireless/ralink/... and it's dated October 2026, so like… future-coded of her. anyway stream rt2x00_desc_write(9), stay hydrated, and remember: write the word, don't forget the word. 🎀🌸🦋
