✨ NAME ✨

okay so bestie, welcome to the Kernel API Manual, section 9 💅 — this page is all about msm_dp_link_process_phy_test_pattern_request 🎀, which literally processes new phy link requests. no cap, that's the whole job description 🦋

🌸 SYNOPSIS 🌸

       msm_dp_link_private *link );

like, that's the whole signature, she's right there 👑

💖 ARGUMENTS 💖

  • link — the Display Port Driver data 🫶 that's it, that's the one argument, she's carrying all the driver vibes

🌈 DESCRIPTION 🌈

bestie listen 👂 this function handles new phy link pattern requests that are initiated by the sink — the sink is the one kicking things off here, not us, we're just built to respond ✨

and here's the return tea ☕ so you don't get caught lacking:

  • if a phy link pattern has been processed, she returns 0 — slay, we ate 💅
  • otherwise she returns -EINVAL — not an error exactly, just "nah, didn't process that one" 💀
ngl the return value is doing a lot of the talking here — 0 means it went through, -EINVAL means it did not. don't overthink the vibe check 🔥
