vsp1_dl_list_add_chain(9)

💅 vsp1_dl_list_add_chain(9) 💅

okay so welcome to the Kernel API Manual, bestie. this one is short, sweet, and all about chaining display lists together like it’s a group chat and everybody’s getting added to the same thread 💬✨

---

🎀 NAME 🎀

vsp1_dl_list_add_chain — add a display list to a chain

---

✨ SYNOPSIS ✨

int vsp1_dl_list_add_chain (struct vsp1_dl_list *head , struct
       vsp1_dl_list *dl );

---

🫶 ARGUMENTS 🫶

• head — the head display list 👑
• dl — the new display list being added to the chain 🌸

---

💖 DESCRIPTION 💖

So the whole vibe here is: you take a display list and add it to an existing display list chain. That’s it, that’s the function 🫶

The chained lists are automatically processed by the hardware, with no intervention from the CPU. no cap, the hardware just handles it 🔥

A display list end interrupt will only complete after the last display list in the chain has completed processing. so like… the interrupt waits its turn, periodt 💅

Adding a display list to a chain passes ownership of the display list to the head display list item. custody transfer, but make it kernel 👑

The chain is released when the head dl item is put back with __vsp1_dl_list_put. that’s the cleanup moment, bestie 🧹✨
