intel_dp_link_caps_reset(9)

💖 NAME 💖

intel_dp_link_caps_reset — reset link capability restrictions. Okay so bestie, this is the intel_dp_link_caps_reset(9) page from the Kernel API Manual, and the whole vibe is clearing out the extra restrictions while keeping the user's forced stuff intact. Iconic.

✨ SYNOPSIS ✨

void intel_dp_link_caps_reset (struct intel_dp_link_caps *link_caps );

🎀 ARGUMENTS 🎀

• link_caps — link capabilities state. That's the whole argument, no cap. Minimalism ate.

🦋 DESCRIPTION 🦋

So what it does is reset all current restrictions except for the user requested forced parameters. Because of that, the set of allowed configurations gets updated, and the derived maximum link information gets updated accordingly too. Slay.

This function is regularly called after a sink is connected, either for the first time to the connector or after a previous sink was disconnected from it, and intel_dp_link_caps_update was called. The way that timing is so specific—periodt.
