STRUCT MTK_GPUEB_MBOX_CHAN_DESC(9)

💅 struct mtk_gpueb_mbox_chan_desc(9) 💅

okay so bestie, we're deep in the Kernel API Manual right now — section 9, kernel-space girlie territory — and today's main character is this little struct. she's not doing a lot, but what she does, she does flawlessly. ✨

🌸 NAME 🌸

struct mtk_gpueb_mbox_chan_desc — per-channel constant data 💖

like, literally just the fixed facts about one mailbox channel. no drama, no mutation, just vibes and constants. 🎀

---

✨ SYNOPSIS ✨

here's the whole glow-up, bestie — every field, exactly as it ships:

struct mtk_gpueb_mbox_chan_desc {
    const char *name;
    const u8 num;
    const u16 tx_offset;
    const u8 tx_len;
    const u16 rx_offset;
    const u8 rx_len;
 };

no cap, that's the entire struct. she's compact. she's iconic. she ate. 👑

🎀 Members 🎀

every field gets her moment, so let's go one by one 🫶

• name — the name of this channel. her government name, her birth certificate, the whole thing 💫
• num — the index of this channel, and it starts at 0. zero-indexed, because of course it is 🙈
• tx_offset — the byte offset measured from the mmio base, for the outgoing data. that's where the send-side data lives 📤
• tx_len — the size, in bytes, of the outgoing data on this channel. how much you're actually sending 🌈
• rx_offset — the bytes offset measured from the mmio base, for the incoming data. that's where the receive-side data lives 📥
• rx_len — the size, in bytes, of the incoming data on this channel. how much you're actually getting back ⭐

quick vibe check: tx_offset and rx_offset are both measured from the mmio base — don't let anyone tell you otherwise, bestie 💀
