💖 dmub_srv_fb_cmd_execute(9) 💖

Okay so this page is dmub_srv_fb_cmd_execute(9), folded in fresh from the Kernel API Manual, and it's giving “small function, main-character energy” ✨

🌸 NAME 🌸

dmub_srv_fb_cmd_execute — executes a queued sequence to the dmub. That's the whole name, bestie 💅

🦋 SYNOPSIS 🦋

The signature is literally right here, no edits, no cap:

enum dmub_status dmub_srv_fb_cmd_execute (struct dmub_srv *dmub );

🎀 ARGUMENTS 🎀

• dmub — the dmub service. Hand it over, that's the one 🫶

✨ DESCRIPTION ✨

Okay so this function begins execution of queued commands on the dmub. It's the “start the queued sequence” moment, and the vibes are immaculate. No extra plot twists added, fr fr 🔥

💅 RETURN 💅

• DMUB_STATUS_OK — success, we love to see it 💖
• DMUB_STATUS_INVALID — unspecified error, not iconic 😭
