ti_sci_cmd_...ce_exclusive(9)

💅 NAME 💅

ti_sci_cmd_get_device_exclusive — the command where you ask for a device managed by TISCI that your host gets to own exclusively, no sharing, no crumbs 💖

Quick lil housekeeping bestie: this page lives in the Kernel API Manual, and its header goes by ti_sci_cmd_...ce_exclusive(9) — yeah the title's truncated, don't @ me, that's just how it printed 😭

---

✨ SYNOPSIS ✨

int ti_sci_cmd_get_device_exclusive (const struct ti_sci_handle *handle
, u32 id );

---

🎀 ARGUMENTS 🎀

• handle — your pointer to the TISCI handle, which you get from *ti_sci_get_handle 🫶 like your lil VIP pass to the whole thing
• id — the Device Identifier, aka which device you're claiming 👑

---

🌸 DESCRIPTION 🌸

Okay so this is the "request for the device" call. You're asking for it, officially, on the record 💅

⚠️ NOTE, and this one is loud: the client MUST maintain integrity of usage count by balancing get_device with put_device. No refcounting is managed by the driver for that purpose. So no cap, if you get_device and then ghost the put_device, that's on you, not the driver 🙈

---

🦋 RETURN 🦋

0 if all went fine ✨ — otherwise it returns the appropriate error, so like, vibe check your return value ngl 💀
