STRUCT MDP_IPI_COMM_ACK(9)

✨ struct mdp_ipi_comm_ack 💅

okay bestie, so this is a page from the Kernel API Manual and it's all about struct mdp_ipi_comm_ack — say that five times fast, i literally can't 😭 — and ngl it's a cute little struct that exists for VPU_MDP_DEINIT_ACK and VPU_MDP_PROCESS_ACK. that's the whole name section, we ate. 🎀

---

🌸 SYNOPSIS 🌸

here's the whole vibe, bestie, character for character — do not touch, she's perfect:

struct mdp_ipi_comm_ack {
    uint32_t msg_id;
    uint32_t ipi_id;
    uint64_t ap_inst;
    uint32_t vpu_inst_addr;
    int32_t status;
 };

like, five fields, zero notes, main character energy fr fr. 🔥

💖 Members 💖

okay so every single member, one by one, no skipping, we're being thorough girlies:

• msg_id — this one's the message id, and it holds VPU_MDP_DEINIT_ACK or VPU_MDP_PROCESS_ACK. pick your fighter. ✨
• ipi_id — it's IPI_MDP, that's the one, that's the value, periodt. 🫶
• ap_inst — the AP mtk_mdp_vpu address. literally where it lives. 📍
• vpu_inst_addr — the VPU MDP instance address, so like, the other address, don't mix them up bestie 💀
• status — the VPU exeuction result. (yes, "exeuction", that's genuinely how the original spells it and honestly? iconic typo, i'm keeping her 🎀💅)

girlie please remember: status is a int32_t and it's the execution result — so if things go sideways that's where you look first, iykyk 🙈

🦋 SEE ALSO 🦋

go read these next, bestie, they're in the same house:

• the kernel file ./drivers/media/platform/mediatek/mdp/mtk_mdp_ipi.h
• struct mdp_ipi_init(9)
• struct mdp_ipi_comm(9)
• struct mdp_config(9)

like a little friend group, all linked together, so cute 🌈⭐

and that's the whole page!! you understood it, i'm obsessed with you, slay 💜🌷

sign-off time bestie: this came out of ./drivers/media/platform/mediatek/mdp/mtk_mdp_ipi.h, it's dated October 2026, and the footer said struct mdp_ipi_comm_ack(9) — so go forth and ACK responsibly, mwah 🧚💖
