STRUCT TEE_CMD_UNMAP_SHARED_MEM(9)

💅 struct tee_cmd_unmap_shared_mem — like, the Kernel API Manual page you actually wanna read 🎀

okay bestie, sit down, hydrate, and let me tell you about struct tee_cmd_unmap_shared_mem — it's literally the command to unmap shared memory, no cap. This is a Kernel API Manual moment, so yes it's serious, but we can still be cute about it. 💖

---

✨ NAME ✨

struct tee_cmd_unmap_shared_mem — the command to unmap shared memory. That's it, that's the whole vibe. It's giving "cleanup era" and honestly? Obsessed. 🧚

---

🌸 SYNOPSIS 🌸

Here's the whole struct, looking all tiny and iconic:

struct tee_cmd_unmap_shared_mem {
    u32 buf_id;
};

That's the entire thing, bestie — one member, zero drama. Lowkey the most low-maintenance struct in the whole kernel. 💀

---

🦋 Members 🦋

• buf_id — [in] the buffer ID of the memory that's getting unmapped, periodt. You hand it the ID, it knows which shared-memory situation to tear down. Main character energy for a single u32, fr fr. ✨

---

👑 SEE ALSO 👑

Kernel file ./drivers/tee/amdtee/amdtee_if.h — that's the home base, iykyk. 👑

And the whole friend group of structs — go say hi to all of them:

• struct memref(9)
• struct tee_sg_desc(9)
• struct tee_cmd_map_shared_mem(9)
• struct tee_cmd_load_ta(9)
• struct tee_cmd_unload_ta(9)
• struct tee_cmd_open_session(9)
• struct tee_cmd_close_session(9)
• struct tee_cmd_invoke_cmd(9)

Like, that's the entire group chat right there. Map it, then unmap it — balance. 🌈

heads up bestie 🫶: this page lives in ./drivers/tee/amdtee, and it's dated October 2026 — the manual name on the tin is struct tee_...p_shared_mem(9) in case you were wondering why the header got truncated like that. Not me abbreviating, that's just what it says. 😭

and that's the page!! mwah 💋 go unmap some shared memory responsibly, bestie. 🍓✨
