💅 struct drm_dp_vsc_sdp(9) 💅

okay so bestie, welcome to the Kernel API Manual page for struct drm_dp_vsc_sdp — yes, we are literally reading a kernel struct page together, and honestly? iconic. ✨

🌸 NAME 🌸

struct drm_dp_vsc_sdp — drm DP VSC SDP. That's the name, that's the vibe, no cap. 💅

✨ SYNOPSIS ✨

       struct drm_dp_vsc_sdp {
           unsigned char sdp_type;
           unsigned char revision;
           unsigned char length;
           enum dp_pixelformat pixelformat;
           enum dp_colorimetry colorimetry;
           int bpc;
           enum dp_dynamic_range dynamic_range;
           enum dp_content_type content_type;
        };

🎀 Members 🎀

• sdp_type — secondary-data packet type. slay. 🦋
• revision — revision number. keep up, bestie. 🔥
• length — number of valid data bytes. the way this is literally just the count, periodt. ✨
• pixelformat — pixel encoding format. very main character energy. 🌈
• colorimetry — colorimetry format. yes. 💜
• bpc — bit per color. exactly that. 💅
• dynamic_range — dynamic range information. 🌸
• content_type — CTA-861-G defines content types and expected processing by a sink device. that's the lore. 📚

🦋 Description 🦋

This structure represents a DP VSC SDP of drm — literally the whole point — and it is based on DP 1.4 spec [Table 2-116: VSC SDP Header Bytes] and [Table 2-117: VSC SDP Payload for DB16 through DB18]. iconic. 💖
