🌸 intel_dp_li...t_max_config(9) 🌸

okay so bestie, this one's from the Kernel API Manual and it's literally the glow-up guide for intel_dp_link_caps_get_max_config — the function that goes "out of all the configs we're allowed to use rn, which one is The One?" 👑

---

✨ NAME ✨

intel_dp_link_caps_get_max_config — get the maximum config in a given order 🎀

---

✨ SYNOPSIS ✨

bool intel_dp_link_caps_get_max_config (struct intel_dp_link_caps
*link_caps , enum intel_dp_link_caps_order_key order_key , struct
intel_dp_link_caps_filter filter , struct intel_dp_link_config
*max_config );

---

✨ ARGUMENTS ✨

• link_caps — the link capabilities state, aka where all the vibes live 💅
• order_key — the ordering key, used to rank the candidate configurations. it's giving ranking ceremony, main character energy 👑
• filter — a filter for the candidate configurations, so we only look at the ones that pass the vibe check 🦋
• max_config — the returned maximum link configuration. this is where the winner gets announced 🎀

---

✨ DESCRIPTION ✨

So here's the tea, bestie 🍵 — this function finds the last configuration among the currently allowed configurations (filtered by filter, obvi) in the iteration order selected by order_key, and then stores it right into max_config. periodt. 💖

See also:

• enum intel_dp_link_caps_order_key

---

✨ RETURN ✨

It returns true if a maximum config is returned, and false otherwise. no cap, that's the whole thing 🤷‍♀️
