drm_dp_calc_pbn_mode(9)

💖 NAME 💖

okay so welcome to the drm_dp_calc_pbn_mode(9) page in the Kernel API Manual ✨ bestie, this one is literally:

drm_dp_calc_pbn_mode — Calculate the PBN for a mode. 💅

✨ SYNOPSIS ✨

int drm_dp_calc_pbn_mode (int clock , int bpp );

🎀 ARGUMENTS 🎀

• clock — dot clock. 💫
• bpp — bpp as .4 binary fixed point. 🎀

🦋 DESCRIPTION 🦋

This uses the formula in the spec to calculate the PBN value for a mode. no cap, that's the whole vibe — it's giving “spec formula goes brrr” but make it PBN 🔥.
