STRUCT MATRIX_KEYMAP_DATA(9)

💅 struct matrix_keymap_data(9) 💅

okay so welcome to the Kernel API Manual, bestie — today's main character is struct matrix_keymap_data(9) and honestly? it's giving "small but essential." let's get into it 🎀

✨ NAME ✨

struct matrix_keymap_data — the keymap for matrix keyboards, periodt. ⌨️💖

---

🌸 SYNOPSIS 🌸

struct matrix_keymap_data {
    const uint32_t *keymap;
    unsigned int    keymap_size;
 };

that's it. that's the whole vibe. two fields, zero drama. 🦋

• keymap — a pointer to an array of uint32 values, each one encoded with the KEY macro, and together they represent the keymap. iykyk — this is the actual map of what key lives where 🔥
• keymap_size — the number of entries (initialized, babe) in this keymap. literally just the count. no cap 💅

---

💜 Description 💜

so this structure is supposed to be used by platform code to supply keymaps to drivers that implement matrix-like keypads/keyboards. that's the whole job. that's the assignment and it ate. 🍓

platform code → hands over the keymap → driver does driver things. match made in heaven, fr fr ✨
