dc_update_planes_and_stream(9)

💅 dc_update_planes_and_stream(9) — like, the Kernel API Manual era, bestie ✨

okay so picture this: it's the Kernel API Manual, and we're talking about dc_update_planes_and_stream(9). She's a shim. She's iconic. She's literally just here to hand your stuff to somebody else and look cute doing it. 🎀

---

🌸 SYNOPSIS 🌸

bool dc_update_planes_and_stream (struct dc *dc , struct
dc_surface_update *srf_updates , int surface_count , struct
dc_stream_state *stream , struct dc_stream_update *stream_update );

she takes a whole lil friend group of arguments and returns a bool, no cap 💖

---

✨ ARGUMENTS ✨

• dc — the DC structure itself. the main character of this whole situation 👑
• srf_updates — an array of surface update descriptors. like a little stack of notes for each surface, iykyk 🦋
• surface_count — the number of entries in srf_updates. yes bestie, she's counting, that's literally her job 🔢
• stream — the target stream 🎯 the one we're updating, periodt
• stream_update — an optional stream update. optional!! she doesn't need it but she'll take it too 💅

---

💜 DESCRIPTION 💜

so what does she actually do? she packs all those individual arguments into a dc_state_update and forwards the whole thing straight to dc_update_state. that's it. that's the plot. 🫶

the way that this is preserved for out-of-tree and incremental callers — like she's kept around specifically so those callers don't get left on read. iconic of her, honestly. 😭

🔥 RETURN 🔥

• true — on success ✨ slay
• false — on failure 💀 not slay

mwah 💋 that's the whole page, and it comes to you straight from ./drivers/gpu/drm/amd/display/..., dated October 2026, and yes the title is still dc_update_planes_and_stream(9) because she never changes, she just vibes. 🦋✨ see u in the next manpage bestie 🫶💖
