STRUCT KOMEDA_PIPELINE_STATE(9)

🎀 struct komeda_pipeline_state(9) — Kernel API Manual 🎀

okay bestie, we're looking at struct komeda_pipeline_state(9) today, from the Kernel API Manual, and honestly? iconic little struct. let's get into it 💅

---

✨ NAME ✨

struct komeda_pipeline_state — literally the pipeline state struct, that's the whole name, no notes 🔥

---

🌸 SYNOPSIS 🌸

struct komeda_pipeline_state {
    struct drm_private_state obj;
    struct komeda_pipeline *pipe;
    struct drm_crtc *crtc;
    u32 active_comps;
 };

that's the whole vibe right there 🫶

---

🦋 Members 🦋

• obj — this is the one tracking pipeline_state via drm_atomic_commit. main character energy honestly, it's the thing doing the atomic bookkeeping ✨
• pipe — a backpointer to the pipeline. yeah. it points back. that's the whole job 🎀
• crtc — whichever crtc is currently bound. currently! bound! we love a temporary commitment 💖
• active_comps — a bitmask, specifically BIT(component->id) of active components. bitmask besties rise up 🌈

---

💀 NOTE 💀

so here's the tea: unlike the pipeline, pipeline_state does not gather any component_state into it. nope! not even one 🙈 why? because all the components get managed by drm_atomic_commit, that's why. no cap, that's the entire reason 🍓

👑 SEE ALSO 👑

• Kernel file ./drivers/gpu/drm/arm/display/komeda/komeda_pipeline.h — go read it, it's giving source of truth 💜
• struct komeda_component(9)
• struct komeda_component_output(9)
• struct komeda_component_state(9)
• struct komeda_pipeline(9)

the whole komeda friend group honestly, go say hi to all of them 🧚

okay that's the page!! this came from ./drivers/gpu/drm/arm/display/..., dated October 2026, and the header up top was struct komed...peline_state(9) — yes the manual truncated it like that, no we're not fixing it, it's part of the charm 😭💅

slay and stay atomic, bestie ⭐🌸
