okay bestie, you're in the Kernel API Manual and this is the page for ish_fw_start(9) — the manual name is literally right here in the intro so we're being proper-ish for once 🎀

🌸 NAME 🌸

ish_fw_start — Start executing ISH main firmware ✨

No cap, that's the whole name-and-one-liner combo.

✨ SYNOPSIS ✨

here's the signature, copy it exactly and don't let autocorrect touch it:

int ish_fw_start (struct ishtp_cl_data *client_data );

🎀 ARGUMENTS 🎀

• client_data — the client data instance, periodt.

💅 DESCRIPTION 💅

Okay so this function sends a message to the Shim firmware loader to start the execution of ISH main firmware. That's it, that's the vibe — a little message-sending moment so the main firmware can get its main-character arc going 👑✨

🫶 RETURN 🫶

• 0 for success 🎉
• a negative error code for failure 😭
