DMC FIRMWARE SUPPORT(9)

💖 DMC Firmware Support 💖

Okay bestie, welcome to the DMC Firmware Support page from the Kernel API Manual, section 9 — it’s giving kernel-core, no cap 💅✨

From gen9 onwards, there’s a newly added DMC — that’s the Display microcontroller — hanging out in the display engine. Its whole vibe? Save and restore the state of the display engine when it enters into a low-power state and comes back to normal. Periodt. 🔥
