STRUCT DRM_DP_DESC(9)

💅 struct drm_dp_desc(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for struct drm_dp_desc, the little glow-up of a struct that holds a DisplayPort branch/sink device descriptor. she's small, she's iconic, she knows things about your monitor 🫶

---

🌸 NAME 🌸

struct drm_dp_desc — the DP branch/sink device descriptor, aka the receipt for whatever DisplayPort device just walked into the chat 💅

---

✨ SYNOPSIS ✨

here's the whole fit, no notes:

struct drm_dp_desc {
    struct drm_dp_dpcd_ident ident;
    u32 quirks;
 };

not her being literally two fields and still carrying the entire vibe check of your DP hardware 😭 🔥

👑 Members 👑

okay let's meet the cast, main character energy only:

• ident — the DP device identification, and it lives at DPCD 0x400 if you're a sink or 0x500 if you're a branch 🎀 so like, know your address bestie.
• quirks — the quirks field ✨ and no, you don't just peek at it raw — use drm_dp_has_quirk to query for the quirks, that's literally the whole point 🦋
