DMC FLIP QUEUE(9)

💅 DMC Flip Queue 💅

okay so bestie, this is the DMC Flip Queue(9) page from the Kernel API Manual, and it's literally serving ring-buffer-in-firmware realness. 🎀

A flip queue is a ring buffer implemented by the pipe DMC firmware. The driver inserts entries into the queues to be executed by the pipe DMC at a specified presentation timestamp (PTS). No cap, that's the whole vibe. ✨

Each pipe DMC provides several queues:

• 1 general queue — two DSB buffers executed per entry 🦋
• 3 plane queues — one DSB buffer executed per entry 🌸
• 1 fast queue — deprecated 👀
