STRUCT SHARE_OBJ(9)

💖 NAME 💖

Okay bestie, meet struct share_obj — the DTCM (Data Tightly-Coupled Memory) buffer shared with AP and VPU. This is the struct share_obj(9) page from the Kernel API Manual, and it's giving “small but important kernel struct” energy. 💅✨

✨ SYNOPSIS ✨

       struct share_obj {
           s32 id;
           u32 len;
           unsigned char share_buf[SHARE_BUF_SIZE];
        };

🎀 Members 🎀

• id — the IPI id. that's it, that's the description, periodt. 💅
• len — the share buffer length. slay, we love a length field. 📏
• share_buf — the share buffer data. literally the data in the share buffer, no cap. 💾

mwah 💋 this page is sourced from ./drivers/media/platform/media..., dated October 2026, and yes bestie it's still struct share_obj(9). bye, ily, go read the other VPU structs 🫶🌈
