STRUCT PVR_KCCB_FENCE(9)

okay so bestie, welcome to the struct pvr_kccb_fence(9) page from the Kernel API Manual — she's lowkey iconic and highkey here to explain a fence object 💅✨

🌸 NAME 🌸

struct pvr_kccb_fence — a fence object used to wait for a KCCB slot, periodt. No cap, that's the whole vibe.

✨ SYNOPSIS ✨

the whole struct is literally this, bestie:

       struct pvr_kccb_fence {
           struct dma_fence base;
           struct list_head node;
        };

🫶 Members 🫶

• base — the base dma_fence object. it's giving foundation, main character energy, the whole fence situation 💖
• node — the node used to insert the fence in the pvr_device::kccb::waiters list. think of it as the little handle that lets this fence slide into the right group chat 🦋
