STRUCT VENC_AP_IPI_MSG_INIT(9)

💖 struct venc_ap_ipi_msg_init(9) 💖

Okay so welcome to the Kernel API Manual, bestie — today's main character is struct venc_ap_ipi_msg_init, and it's literally the AP to VPU init cmd structure. Tiny struct, big main character energy. Let's get into it. ✨

🌸 NAME 🌸

struct venc_ap_ipi_msg_init — AP to VPU init cmd structure 🎀

🦋 SYNOPSIS 🦋

struct venc_ap_ipi_msg_init {
    uint32_t msg_id;
    uint32_t reserved;
    uint64_t venc_inst;
};

🎀 Members 🎀

• msg_id — the message id, and it's giving AP_IPIMSG_XXX_ENC_INIT. That's the whole assignment. 💅
• reserved — reserved for future use, periodt. Here's the tea: the vpu is running in 32bit. Without this reserved field, if the kernel runs in 64bit, this struct size will be different between kernel and vpu — so this field is lowkey carrying the whole vibe check. Do not touch. 🫶
• venc_inst — the AP encoder instance, typed as struct venc_vp8_inst/venc_h264_inst *. Pointer moment, iconic. ⭐
