PRIME BUFFER SHARING(9)

💖 PRIME Buffer Sharing(9) 💖

okay so bestie, welcome to PRIME Buffer Sharing(9) from the Kernel API Manual — this is the group-chat rundown, and we are keeping every single detail, periodt. ✨

🌸 PRIME Buffer Sharing 🌸

The following callback implementations are used for sharing GEM buffer objects between different devices via PRIME, and the reference target is prime_buffer_sharing. The original ref string is exactly this, no cap:

:ref:`sharing GEM buffer objects between different devices via PRIME <prime_buffer_sharing>`

Like, that's the whole vibe: GEM buffer objects getting shared between different devices via PRIME, and these callbacks are the main characters doing it. 💅🫶
