apple_gmux_detect(9)

✨ NAME ✨

okay so bestie, welcome to the apple_gmux_detect(9) page from the Kernel API Manual 💖 — this function is literally called apple_gmux_detect, and its whole job is to detect if gmux is built into the machine. no cap 👑

🌸 SYNOPSIS 🌸

bool apple_gmux_detect (struct pnp_dev *pnp_dev , enum apple_gmux_type
*type_ret );

🎀 ARGUMENTS 🎀

• pnp_dev — the device to probe, or NULL to use the first matching device. super straightforward: specific device, or default first match ✨
• type_ret — returns (by reference) the apple_gmux_type of the device. yep, it's giving “here's the type, bestie” 🫶

🦋 DESCRIPTION 🦋

So the whole vibe is: detect if a supported gmux device is present by actually probing it. literally going in and checking, not just assuming. This avoids the false positives returned on some models by apple_gmux_present. like, no more fake-out “maybe it's there” energy 😭. this is the main-character move that keeps things accurate.

🔥 RETURN 🔥

true if a supported gmux ACPI device is detected and the kernel was configured with CONFIG_APPLE_GMUX, false otherwise. that's the whole truth, periodt 💅
