💖 struct arm_smccc_quirk(9) 💖

okay so this is a page from the Kernel API Manual, and honestly? it's a whole lil struct and we're gonna get into it. bestie, buckle up 🎀

✨ NAME ✨

struct arm_smccc_quirk — Contains quirk information 💅

like, that's literally it. it holds quirk info. no cap.

🌸 SYNOPSIS 🌸

struct arm_smccc_quirk {
    int id;
    union {
      unsigned long a6;
    } state;
 };

look at her. she's small. she's iconic. she has exactly two things in her and one of them is a union 👑

🦋 Members 🦋

• id — the quirk identification 🏷️ like, which quirk is this. identity crisis? no ma'am, she knows who she is.
• state — quirk specific information ✨ the actual deets, stored in that little union, and inside the union there's literally just one thing: unsigned long a6. that's the whole vibe. iykyk.
