STRUCT MTK_GPUEB_MBOX_CHAN(9)

🌸 struct mtk_gpueb_mbox_chan(9) 🌸

okay so bestie, welcome to the Kernel API Manual 💅 — this little cutie is a struct, and it's literally the per-channel runtime data for the mtk_gpueb mailbox situation. think of it as the main-character glow-up each mailbox channel gets at runtime ✨

✨ NAME ✨

struct mtk_gpueb_mbox_chan — per-channel runtime data 🎀

like yes it's just a struct, but it's the struct that holds all the runtime deets for one single channel. no cap.

---

🦋 SYNOPSIS 🦋

struct mtk_gpueb_mbox_chan {
    struct mtk_gpueb_mbox *ebm;
    char *full_name;
    u8 num;
    atomic_t rx_status;
    const struct mtk_gpueb_mbox_chan_desc *c;
 };

periodt. that's the whole vibe. now let's meet the members one by one 💖

👑 Members 👑

• ebm — pointer to the parent struct mtk_gpueb_mbox mailbox 🌈 like, this channel's mom, basically. it knows who it belongs to.
• full_name — descriptive name of channel for IRQ subsystem 🏷️ this is the pretty name the IRQ subsystem gets to see. make it descriptive, bestie, it's literally in the name.
• num — channel number, starting at 0 🔢 so the first one is 0, not 1. we're zero-indexed in this house, always.
• rx_status — signifies whether channel reception is turned off, or full 📬 an atomic_t, so it's lowkey built for concurrency — it's telling you whether this channel's reception is off or full.
• c — pointer to the constant struct mtk_gpueb_mbox_chan_desc channel data 🧊 the const is doing the heavy lifting here, it's the immutable description data for the channel. icon behavior, honestly.

🫶 friendly reminder: num starts at 0 and rx_status is an atomic_t — those aren't vibes, those are facts. iykyk 💀
