STRUCT EC_PARAMS_FLASH_WRITE(9)

💅 struct ec_params_flash_write(9) — Kernel API Manual ✨

Okay bestie, buckle up, because we're deep in the Kernel API Manual today and this one is literally a two-field struct. Peak "small but mighty" energy. 🎀

---

🌸 NAME 🌸

struct ec_params_flash_write — the parameters for the flash write command. That's it, that's the whole vibe. 🦋

---

⭐ SYNOPSIS ⭐

struct ec_params_flash_write {
    uint32_t offset;
    uint32_t size;
 };

Look at her. Two uint32_ts. Immaculate. No cap. 💖

✨ offset

Byte offset to write. As in, where in the flash we're dropping this. Your starting coordinate, your little address home base. 📍

✨ size

Size to write in bytes. How much we're putting down. Know your numbers before you commit, bestie. 📏

ngl the flash read / erase / protect / select cluster right there in the middle is giving main character energy. iykyk. 💀

Okay that's the whole page, bestie — go forth and write some flash. 💜 This iconic little doc came out of ./include/linux/platform_data and is dated October 2026, so yeah, she's got a timestamp and she's proud of it. 🧚⭐
