tb_switch_is_icm(9)

💖 NAME 💖

Hey bestie, this is tb_switch_is_icm(9) from the Kernel API Manual ✨ — the function that answers is the switch handled by ICM firmware? That's literally the whole vibe. 🦋

📜 SYNOPSIS 📜

bool tb_switch_is_icm (const struct tb_switch *sw );

🎀 ARGUMENTS 🎀

• sw — the switch to check, periodt 💅

💫 DESCRIPTION 💫

Okay so in case there is a need to differentiate whether ICM firmware or SW CM is handling sw, this function can be called. It is valid to call this after tb_switch_alloc and tb_switch_configure has been called — and bestie, that's the latter only for the SW CM case. 👑

🔥 RETURN 🔥

You get true if the switch is handled by ICM, and false if it's handled by software CM. Simple, iconic. 💖
