💅 drm_dp_vsc_sdp_supported(9) — the "is VSC SDP even a thing here" check

Okay bestie, so this is a page from the Kernel API Manual, and it's called drm_dp_vsc_sdp_supported. Yes the name is a whole mouthful, no I will not be shortening it, it's giving "I was named by a committee and I ate". Let's get into it 🫶

✨ SYNOPSIS ✨

bool drm_dp_vsc_sdp_supported (struct drm_dp_aux *aux , const u8
dpcd[DP_RECEIVER_CAP_SIZE] );

That's the whole vibe. It hands you back a bool. Iconic, minimal, no notes. 🔥

🎀 ARGUMENTS 🎀

  • aux — the DisplayPort AUX channel. That's the little side-channel your DisplayPort link uses to gossip with the other end 💬
  • dpcd — DisplayPort configuration data. The receipts, basically 📋

🌸 DESCRIPTION 🌸

So what does it actually do? It returns true if vsc sdp is supported, and returns false otherwise. That's it. That's the whole function. Short king behavior, honestly 👑✨

ngl it's a one-liner of a description and we respect it for that. No fluff, no filler, just a yes-or-no vibe check on VSC SDP. 💅

Like… the way that list just keeps going. She said "you WILL know the whole DP family" and she meant it 🧚💜
