STRUCT DRM_AMD_VSDB_INFO(9)

💅 struct drm_amd_vsdb_info(9) 💅

okay so this is a page from the Kernel API Manual bestie, and we're about to get into some AMD-specific display metadata. no cap, it's a whole struct and it's lowkey iconic. let's go ✨

---

🌸 NAME 🌸

struct drm_amd_vsdb_info — literally the AMD-specific VSDB information holder. that's it, that's the vibe 🫶

---

🎀 SYNOPSIS 🎀

here's the whole thing, character for character, don't @ me:

struct drm_amd_vsdb_info {
    u8 version;
    bool replay_mode;
    u8 panel_type;
    struct drm_luminance_range_info luminance_range1;
    struct drm_luminance_range_info luminance_range2;
 };

like, five fields. tidy. we stan a compact struct 💜

---

🦋 Members 🦋

okay so let's meet the cast, one by one:

• version — the version of the Vendor-Specific Data Block (VSDB). yes bestie, the block itself has a version. main character energy tbh 👑
• replay_mode — whether Panel Replay is supported. it's a bool, so it's giving yes/no, on/off, slay/not-slay 🌈
• panel_type — the panel technology type. u8 flavored, so go look up your panel lore elsewhere, this is just the type tag 🏷️
• luminance_range1 — luminance for max back light. brightest-baddie energy 🔥
• luminance_range2 — luminance for min back light. dim-but-still-present energy 🌙

---

✨ Description ✨

so the whole point of this struct: it holds the information that gets parsed from the AMD Vendor-Specific Data Block (VSDB) version 3. that's the entire description and honestly? it ate. short, sweet, no filler 💅

heads up: it's version 3 specifically, per the manual. don't come at me with version 2 questions, this page doesn't cover them 🙈
