MEI_HDCP CLIENT DRIVER(9)

💖 MEI_HDCP Client Driver 💖

okay so welcome to the <rainbow>MEI_HDCP Client Driver(9)</rainbow> manual page bestie, this is the kernel API manual and it's honestly shorter than my attention span but we're gonna make it cute ✨

🌸 DESCRIPTION 🌸

so here's the tea: the mei_hdcp driver is literally a translation layer between the HDCP 2.2 protocol implementer (I915) and ME FW 🫶

that's it. that's the whole vibe. it translates HDCP 2.2 negotiation messages into ME FW command payloads, and vice versa — both directions, no cap 🔁

it's giving fluent in two languages and honestly? iconic 💅
