okay so bestie, welcome to the Kernel API Manual ✨ and today's main character is amvdec_set_canvases — it's the one that maps VB2 buffers to canvases. no cap, that's literally the whole vibe of the NAME section 🎀

🌸 SYNOPSIS 🌸

int amvdec_set_canvases (struct amvdec_session *sess , u32 reg_base[] ,
       u32 reg_num[] );

it's giving "returns an int, takes a session and two arrays" — short, sweet, iconic 👑

🦋 ARGUMENTS 🦋

here's the breakdown, and yes you need all of them:

• sess — current session 💖 like, the whole session you're working with right now
• reg_base — Registry bases of where to write the canvas indexes 📝 this is the "where do the canvas indexes go" list
• reg_num — number of contiguous registers after each reg_base (including it) 🔢 so it counts that base register too, don't forget, iykyk
