STRUCT TEGRA_CHANNEL_BUFFER(9)

🎀 struct tegra_channel_buffer(9) 🎀

okay bestie, so this one comes straight out of the Kernel API Manual and it's literally the whole vibe check for the Tegra video channel buffer ✨ it's giving "small struct, big responsibilities" and honestly? obsessed.

🌸 NAME 🌸

struct tegra_channel_buffer — video channel buffer 💖

like, that's it, that's the whole name, short and iconic, no cap.

---

✨ SYNOPSIS ✨

here's the shape of it, copied exactly so you don't have to squint at the source 🫶

struct tegra_channel_buffer {
    struct vb2_v4l2_buffer buf;
    struct list_head queue;
    struct tegra_vi_channel *chan;
    dma_addr_t addr;
    u32 mw_ack_sp_thresh[GANG_PORTS_MAX];
};

💅 Members 💅

okay so these are the actual fields, one by one, no skipping, we don't do that here 😌

• buf — the vb2 buffer base object, aka the whole foundation of this thing, the main character energy of the struct 🔥
• queue — the buffer's list entry inside the channel's queued buffers list, your lil place in line bestie 🎀
• chan — the channel that uses the buffer, like its assigned bestie fr fr 💜
• addr — the Tegra IOVA buffer address for VI output, that's the actual address, no guessing ✨
• mw_ack_sp_thresh — the MW_ACK_DONE syncpoint threshold that corresponds to the capture buffer, indexed up to GANG_PORTS_MAX 👑
