tee_shm_register_kernel_buf(9)

🌸 NAME 🌸

okay so bestie, this page is all about tee_shm_register_kernel_buf — it registers kernel shared memory for a particular TEE client driver. that's the whole vibe. 💅

This one lives in the Kernel API Manual, so like… yeah, kernel API manual energy. ✨

---

🎀 SYNOPSIS 🎀

struct tee_shm * tee_shm_register_kernel_buf (struct tee_context *ctx ,
void *addr , size_t length );

literally one function, three args, and it hands you back a struct tee_shm *. no cap. 🫶

---

💖 ARGUMENTS 💖

• ctx — the TEE context for shared memory registration. it's the context, bestie, it's giving "who am i doing this for" energy.
• addr — kernel buffer address. the actual address, in the kernel. iconic of it. ⭐
• length — kernel buffer length. and also, lowkey, this line is where the page tells you it returns a pointer to 'struct tee_shm' on success or an ERR_PTR on failure. so like… check your return value, okay? 😭

fr fr, on failure you get an ERR_PTR — don't just assume it worked and start dereferencing. that's not the move. 💀
