ti_sci_cmd_get_device(9)

💖 NAME 💖

okay bestie, welcome to the ti_sci_cmd_get_device(9) page from the Kernel API Manual — yes, that long icon name, we're doing her justice. ✨

ti_sci_cmd_get_device — the command to request for device managed by TISCI that can be shared with other hosts. Periodt. 💅

✨ SYNOPSIS ✨

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

🫶 ARGUMENTS 🫶

• handle — Pointer to TISCI handle as retrieved by *ti_sci_get_handle. That's your golden ticket, bestie.
• id — Device Identifier. Like the device's little name tag at the function party.

🌸 DESCRIPTION 🌸

Request for the device — that's the whole vibe. She's asking for a device managed by TISCI that can be shared with other hosts, which is lowkey iconic for firmware stuff. 🦋

⚠️ NOTE: the client MUST maintain integrity of usage count by balancing get_device with put_device. No refcounting is managed by driver for that purpose.

So fr fr, you get it, you put it, you keep that count balanced — the driver is not doing the refcounting for you. That's a you-and-your-usage-count situation, bestie. 💀

💀 RETURN 💀

0 if all went fine, else return appropriate error. No cap. ✅
