ENUM ISH_LOADER_COMMANDS(9)

💅 enum ish_loader_commands(9) 💅

okay so bestie, we're deep in the Kernel API Manual today and honestly? this one is a whole mood. it's a tiny little enum — three constants, no cap — that tells the ISH loader host what it's supposed to be doing. main character energy for a firmware loader, fr fr. let's get into it 🫶

---

✨ NAME ✨

enum ish_loader_commands — the ISH loader host commands, periodt. that's it, that's the vibe check 💖

---

🌸 SYNOPSIS 🌸

enum ish_loader_commands {
    LOADER_CMD_XFER_QUERY ,
    LOADER_CMD_XFER_FRAGMENT ,
    LOADER_CMD_START

};

like, look at her. three commands, sitting there, slaying 🎀

---

🦋 Constants 🦋

• LOADER_CMD_XFER_QUERY — the "hey bestie what can u even do" command. it queries the Shim firmware loader for its capabilities ✨
• LOADER_CMD_XFER_FRAGMENT — moves one firmware image fragment at a time, lowkey one bite at a time 🍓 and here's the thing: the command may be executed multiple times until the entire firmware image is downloaded to SRAM. so yeah, she's a repeat girly. no cap 🔥
• LOADER_CMD_START — the moment we've all been waiting for: start executing the main firmware. it's giving finale. it's giving main character. it's giving go 💅👑
