🎀 NAME 🎀

usb4_dp_port_set_granularity — set granularity for the bandwidth values ✨

✨ SYNOPSIS ✨

int usb4_dp_port_set_granularity (struct tb_port *port , int granularity
       );

🌸 ARGUMENTS 🌸

  • port — DP IN adapter. that's the port we're doing the thing to, no cap 💅
  • granularity — granularity in Mb/s. supported values are 1000, 500 and 250 🎀

🦋 DESCRIPTION 🦋

this one sets the granularity used with the estimated, allocated and requested bandwidth. that's the whole vibe — it's giving "tell the bandwidth math what step size to use" ⭐

💀 RETURN 💀

  • 0 — on success. slay, it worked 💖
  • -EOPNOTSUPP — if the adapter does not support this. the adapter said "not today" 🙈
  • Negative errno — another error occurred. some other little gremlin showed up 😭
