dm_test_rep...etup_success(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the Kernel API Manual ✨ — this lil page is titled dm_test_rep...etup_success(9) up top (the header squishes it, adorable of it) but its actual government name is dm_test_replay_link_setup_success. she's a KUnit test and she's lowkey iconic 💅

🎀 NAME 🎀

dm_test_replay_link_setup_success — verifies the coasting vtotal configuration. that's it, that's the job 🫶

✨ SYNOPSIS ✨

void dm_test_replay_link_setup_success (struct kunit *test );

🌸 ARGUMENTS 🌸

  • test — the KUnit test context. it's the little group-chat the test runs inside, basically 💬

💖 DESCRIPTION 💖

so picture this: Replay is supported but it's not enabled yet — like the feature is in the chat but hasn't sent a message 🙈

in that exact situation, amdgpu_dm_link_setup_replay should:

  • calculate the link-off frame count 🔥
  • set the coasting vtotal values ✨
  • and then return true — periodt 💅

no cap, that's what this test is checking for 👑
