PCODE(9)

💖 PCODE 💖

okay bestie, this is PCODE(9) from the Kernel API Manual ✨ and it’s literally the Xe component in charge of interfacing with the PCODE firmware. No cap.

It shall provide a very simple ABI to the other Xe components, but be the single and consolidated place that will communicate with PCODE. Main character energy for firmware chats 👑.

All read and write operations to PCODE will be internal and private to this component. Not me leaking PCODE ops outside the component, periodt 💅.

🌈 What’s next: 🌈

• PCODE hw metrics
• PCODE for display operations
