typec_get_ca...svdm_version(9)

🌈 typec_get_ca...svdm_version(9) — Kernel API Manual 🌈

okay bestie, you found the Kernel API Manual page for typec_get_ca...svdm_version(9). It’s lowkey niche, highkey useful, and it’s all about the cable’s negotiated SVDM Version. Let’s get into it, no cap. 💖

✨ NAME ✨

typec_get_cable_svdm_version — Get cable negotiated SVDM Version

🌸 SYNOPSIS 🌸

int typec_get_cable_svdm_version (struct typec_port *port );

🎀 ARGUMENTS 🎀

• port — USB Type-C Port.

💅 DESCRIPTION 💅

Bestie, this one gets the negotiated SVDM Version for the cable. The Version is set to the port default value based on the PD Revision during cable registration — yes, during cable registration — and it gets updated after a successful Discover Identity if the negotiated value is less than the default. That’s the whole flow, periodt. ✨

Returns usb_pd_svdm_ver if the cable has been registered; otherwise you get -ENODEV. That’s the return vibe. 🫶
