okay so bestie, welcome to the Kernel API Manual ✨ — this one's a tiny little function from the Thunderbolt corner of the kernel, and honestly? she's short but she's iconic 🎀

🌸 NAME

tb_lc_is_clx_supported — check whether CLx is supported by the lane adapter 🦋

✨ SYNOPSIS

bool tb_lc_is_clx_supported (struct tb_port *port );

yes that's the whole thing, she's a one-liner, no cap 🙈

🎀 ARGUMENTS

  • port — the lane adapter 💫 (that's the port we're asking about, bestie, keep up)

💖 DESCRIPTION

okay so here's the tea ☕ — the TB_LC_LINK_ATTR_CPS bit reflects whether the link supports CLx, and that includes active cables if they're connected on the link 🔥

so like, the bit is the whole vibe check here. if that bit's in a good mood, the link is down with CLx. literally that's it 💅

⭐ RETURN

true if CLx is supported, false otherwise 🫶 — clean, simple, no plot twist, we love that for us 😭
