xe_sysctrl_init(9)

🎀 NAME — xe_sysctrl_init(9) in the Kernel API Manual 🎀

xe_sysctrl_init — Initialize System Controller subsystem. That's the name, bestie, and it's lowkey iconic. 💅

✨ SYNOPSIS ✨

int xe_sysctrl_init (struct xe_device *xe );

Okay bestie, that's the whole signature, copied exactly so you can trust it. No cap. 🫶

🌸 ARGUMENTS 🌸

• xe — the xe device instance. Like, the one and only struct xe_device * you're handing over. ✨

💖 DESCRIPTION 💖

This is the entry point for System Controller initialization, and xe_device_probe is the one that calls it. So the probe happens, and then this function slides in to do its thing. 👑

It does a platform-support check, then initializes the system controller. That's the whole job, and it ate. periodt. 💅

🔥 RETURN 🔥

• 0 on success — slay, we love a clean return. ✅
• an error code on failure — not slay, but at least you know. 😭
