🎀 dc_send_upd..._info_to_dmu — Kernel API Manual, section 9 🎀

okay bestie, welcome to the <rainbow>Kernel API Manual</rainbow> — this is the dc_send_upd..._info_to_dmu(9) page, and ngl it's a lil niche but we're gonna slay it together 💅✨

✨ NAME ✨

dc_send_update_cursor_info_to_dmu — literally the function that populates the DMCUB Cursor update info command 🖱️💖

---

🌸 SYNOPSIS 🌸

void dc_send_update_cursor_info_to_dmu (struct pipe_ctx *pCtx , uint8_t pipe_idx );

that's it, that's the whole vibe check. no return value, bestie — it's giving <purple>void</purple> and honestly? iconic 🫶

---

🦋 ARGUMENTS 🦋

• pCtx [in] — the pipe context, aka the whole situation you're handing over 💫
• pipe_idx [in] — the pipe index, a uint8_t lil number that says which pipe we're talking about 🔢

---

💜 DESCRIPTION 💜

so the way that this function works is — it stores the cursor-related information and then passes it into dmub ✨ like, it's the little messenger fairy 🧚 that takes your cursor deets and hands them straight to dmub. that's the whole job. no cap. 🍓

fr fr though, that's genuinely all the page says — don't go reading extra behaviour into it, bestie 🙈
