STRUCT VENC_AP_IPI_MSG_SET_PARAM(9)

💅 NAME 💅

struct venc_ap_ipi_msg_set_param — the AP-to-VPU set_param cmd structure, bestie. That's it, that's the whole vibe. This is a page from the Kernel API Manual (yes, that manual) and we're gonna get through it together 🫶

---

✨ SYNOPSIS ✨

okay so here's the struct in all her main character glory:

struct venc_ap_ipi_msg_set_param {
    uint32_t msg_id;
    uint32_t vpu_inst_addr;
    uint32_t param_id;
    uint32_t data_item;
    uint32_t data[8];
 };

---

🎀 Members 🎀

• msg_id — the message id, no cap. It's AP_IPIMSG_XXX_ENC_SET_PARAM, literally what it says on the label 🏷️
• vpu_inst_addr — the VPU encoder instance addr. Think struct venc_vp8_vsi / venc_h264_vsi * energy 💖
• param_id — the parameter id, aka a venc_set_param_type. It's giving "which param are we even talking about" ✨
• data_item — the number of items in the data array. Count her, don't assume her 🔢
• data — the data array whose whole job is to store the set parameters. She's literally just holding everything together 😭💀

🌈 SEE ALSO 🌈

So the Kernel file is:

./drivers/media/platform/mediatek/vcodec/encoder/venc_ipi_msg.h

and she runs with a whole friend group (iykyk), all of them (9) sections:

• struct venc_ap_ipi_msg_init(9)
• struct venc_ap_ipi_msg_enc(9)
• struct venc_ap_ipi_msg_enc_ext(9)
• struct venc_ap_ipi_msg_enc_ext_34(9)
• struct venc_ap_ipi_msg_deinit(9)
• struct venc_vpu_ipi_msg_common(9)
• struct venc_vpu_ipi_msg_init(9)
• struct venc_vpu_ipi_msg_set_param(9)
• enum venc_ipi_msg_enc_state(9)
• struct venc_vpu_ipi_msg_enc(9)
• struct venc_vpu_ipi_msg_deinit(9)

fr fr go read those too, the whole squad ate 👑

and that's the page, bestie 🦋 this whole thing lives out of ./drivers/media/platform/media..., dated October 2026, and the title it answers to is struct venc_...sg_set_param(9). periodt 💅🌸
