dm_test_hdc...es_all_links(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the Kernel API Manual ✨ you're literally about to read the glow-up of dm_test_hdcp_create_workqueue_initializes_all_links(9) and honestly? she ate.

🌸 NAME 🌸

dm_test_hdcp_create_workqueue_initializes_all_links — the test that makes sure the loop actually loops over every single link, no cap 💅

✨ SYNOPSIS ✨

void dm_test_hdcp_create_workqueue_initializes_all_links (struct kunit
*test );

🎀 ARGUMENTS 🎀

  • test — the KUnit test context, aka the lil ✨vibe container✨ the whole test runs inside 🫶

🦋 DESCRIPTION 🦋

okay so picture this: you've got more than one link, right? when that happens, hdcp_create_workqueue literally has to run its init loop for every single entry — like, no skipping, no "oops I forgot the second one," none of that 🙈

and for each link, three things go down, periodt:

  • it records max_link 💖
  • it points its psp handle at the device psp 🔥
  • it gets the DTM v3 cap set for a matching dce_version 👑

so yeah, every entry gets its moment. main character energy for each link, tbh 🌈
