🎀 SYNOPSIS 🎀

int msm_dp_link_parse_phy_test_params (struct msm_dp_link_private *link

💜 DESCRIPTION 💜

okay so here's the tea: this function goes and parses the DPCD — that's Byte 0x248, write it down, it matters 🖊️ — to figure out which DP PHY link pattern is actually being requested. like it's reading the vibe check that the other end of the cable sent over, and ngl, that's kind of slay of it.

no cap, that's the entire description. short, sweet, ate, left no crumbs 🍓

💀 friendly reminder from your girl: this page is literally titled msm_dp_link..._test_params(9) up top but the function is msm_dp_link_parse_phy_test_params — the truncation is just the man page being dramatic, don't come for me, I'm just reporting what's on the page 🙈

and that's the whole page!! no notes, 10/10, would parse again 💖
