STRUCT AMDGPU_DM_LUMINANCE_DATA(9)

💖 struct amdgpu_dm_luminance_data — Kernel API Manual 💖

okay bestie, so this is a whole page about struct amdgpu_dm_luminance_data(9), and it's giving "tiny struct, big main character energy" ✨ it lives in the Kernel API Manual, and honestly? it's short, it's sweet, and it ate. let's get into it 🎀

---

✨ NAME ✨

struct amdgpu_dm_luminance_data — literally just Custom luminance data 💅 that's the whole vibe, no cap.

---

🦋 SYNOPSIS 🦋

here's the struct in all its glory, copied exactly, don't come for me:

struct amdgpu_dm_luminance_data {
    u8 luminance;
    u8 input_signal;
 };

two members, both u8, both iconic. obsessed 🫶

---

🌸 Members 🌸

• luminance — Luminance in percent 💡 (yes, percent, keep that in mind, bestie, it's not 0-255 like its sibling 👀)
• input_signal — Input signal in range 0-255 🎚️ so like, a full byte range, exactly what you'd expect from a u8. slay.

---

🌈 SEE ALSO 🌈

bestie there is a lot of family here, and this struct is the moment, but the whole friend group at the kernel file ./drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h is also eating:

• struct dm_compressor_info(9)
• struct dm_boot_time_crc_info(9)
• struct dmub_hpd_work(9)
• struct vblank_control_work(9)
• struct idle_workqueue(9)
• struct vupdate_offload_work(9)
• struct amdgpu_dm_backlight_caps(9)
• struct dal_allocation(9)
• struct hpd_rx_irq_offload_work_queue(9)
• struct hpd_rx_irq_offload_work(9)
• struct amdgpu_display_manager(9)
• struct amdgpu_hdmi_vsdb_info(9)

like, twelve whole structs?? it's a whole group chat, iykyk 💀💜

ngl bestie, if you're poking around amdgpu_dm.h you're deep in the DRM/AMD display driver. hydrate, take breaks, and remember: luminance is in percent and input_signal is 0-255 🙈

⭐ and that's the page!! no bugs, no warnings, no environment variables, just a cute little struct being its best self 🧚 source/version is ./drivers/gpu/drm/amd/display/..., dated October 2026, and this whole thing is struct amdg...minance_data(9) — the truncated title is doing its own thing, we love it anyway 💖 Ctrl+D your way out, mwah 🍓
