ENUM INTEL_DP_LINK_CAPS_ORDER_KEY(9)

💖 NAME 💖

enum intel_dp_link_caps_order_key — bestie, this is literally the key you use to order configurations ✨

So this is a page from the Kernel API Manual, and it's all about one tiny enum that decides which way the configs get sorted. Iconic behavior tbh 🎀

---

✨ SYNOPSIS ✨

enum intel_dp_link_caps_order_key {
    INTEL_DP_LINK_CAPS_ORDER_KEY_BW ,
    INTEL_DP_LINK_CAPS_ORDER_KEY_RATE_LANE ,
    INTEL_DP_LINK_CAPS_ORDER_KEY_LANE_RATE ,
    INTEL_DP_LINK_CAPS_ORDER_KEY_NUM

};

---

🎀 Constants 🎀

Ok so these are the four little members of the enum and honestly each one is doing its own thing 💅

• INTEL_DP_LINK_CAPS_ORDER_KEY_BW — orders the configurations by bandwidth first, then by link rate. bandwidth girlies rise 🌸
• INTEL_DP_LINK_CAPS_ORDER_KEY_RATE_LANE — orders the configurations by link rate first, then by lane count 🦋
• INTEL_DP_LINK_CAPS_ORDER_KEY_LANE_RATE — orders the configurations by lane count first, then by link rate 🫶
• INTEL_DP_LINK_CAPS_ORDER_KEY_NUM — the number of ordering keys. that's it. that's the whole vibe. it's the count 👑

---

🦋 DESCRIPTION 🦋

So basically: this enum is how a caller tells you how they want the configuration table to be ordered. It works together with an enum intel_dp_link_caps_order_direction — the two of them together cover iteration queries 💜

Like, you don't just want the table, you want it sorted a specific way, and this is the "specific way" menu ✨

See also, bestie — go look at these:

• struct intel_dp_link_caps_order
• intel_dp_link_caps_get_max_config

no cap, those two are the ones you'll want open in another tab 🙈

ok that's the whole page, you ate that 🍓 go sort some configurations, iykyk
