💅 struct dm_test_color_update_fixture(9) — Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual, and today's main character is this little struct: struct dm_test_color_update_fixture 💖 it's the minimal color update fixture — like, the absolute bare-minimum setup bundle the color-management tests need to actually do their thing. no cap, it's giving "starter pack" energy 🎀

🌸 SYNOPSIS 🌸

struct dm_test_color_update_fixture {
    struct amdgpu_device *adev;
    struct drm_atomic_commit *state;
    struct dm_crtc_state *crtc_state;
    struct dc_stream_state *stream;
    struct dm_plane_state *dm_plane_state;
    struct drm_plane *plane;
    struct dc_plane_state *dc_plane_state;
 };

literally copy that exactly, bestie, every pointer and every semicolon, iykyk 🫶

🦋 Members 🦋

  • adev — the backing amdgpu device. this is the whole reason any of this exists, the parent-friend of the group chat 💜
  • state — the DRM atomic state, and it's carrying adev's DRM device with it. package deal 🎀
  • crtc_state — the DM CRTC state that's actually under test, the one on the runway 🌈
  • stream — the DC stream that crtc_state points at. they're linked, fr fr 🔗
  • dm_plane_state — the DM plane state under test. yes queen, another one 📋
  • plane — the DRM plane that dm_plane_state references. inseparable besties 💫
  • dc_plane_state — the DC plane state under test. the final member, and she ate 🔥

not me listing every single one of those references 💀 but that's the vibe check: if it's in the SEE ALSO, it's in here. no cuts, no "etc.", periodt 👑

🌸 okay that's the whole page, bestie! source is ./drivers/gpu/drm/amd/display/... and this absolute icon dropped October 2026 — go forth and test some color updates, mwah 💋💖
