dc_dmub_srv_...rsor_offload(9)

💅 dc_dmub_srv_control_cursor_offload — a Kernel API Manual moment ✨

okay so bestie, welcome to the Kernel API Manual 🫶 this one's a function page, it's short, it's cute, and it's literally just a toggle for cursor offloading. let's get into it 🎀

✨ NAME ✨

dc_dmub_srv_control_cursor_offload — turns cursor offloading for a stream on or off, that's the whole vibe 💅

🌸 SYNOPSIS 🌸

void dc_dmub_srv_control_cursor_offload (struct dc *dc , struct dc_state
*context , const struct dc_stream_state *stream , bool enable );

like yes she returns void, she takes four args, she's serving function signature realness 👑

🦋 ARGUMENTS 🦋

• dc — pointer to the DC object, your main character struct fr 🫶
• context — the DC context to reference for pipe allocations, she's the receipts for where the pipes go
• stream — the stream to control, this is the one you're doing the cursor thing to ✨
• enable — true to enable cursor offload, false to disable. literally just a bool, no cap 😭

ngl the bool is doing a lot of emotional labor here — true = on, false = off, and that's the entire plot 💀
