COMMAND TRANSPORT (CT).(9)

📦 version 7.3.1, in nixpkgs unstable

💖 Command Transport (CT).

okay bestie, welcome to the Kernel API Manual, section 9 — this is the Command Transport (CT). page, and it's giving “glow-up era for talking to the GuC.” ✨

Buffer based command transport is a replacement for the MMIO based mechanism. no cap, that's the whole vibe. 💅

It can be used to perform both host-2-guc and guc-to-host communication. yes queen, bidirectional chat. 🫶🦋
