π dm_test_rep..._null_stream(9) π
okay so bestie, welcome to the Kernel API Manual β¨ this is a whole little KUnit test page and honestly it's giving "short and iconic" β it's literally four sections and a vibe, so let's get into it π
πΈ NAME πΈ
dm_test_replay_link_setup_null_stream β the test that verifies NULL stream rejection π
like, it's checking that the code says "no β€οΈ" when you hand it nothing.
π¦ SYNOPSIS π¦
void dm_test_replay_link_setup_null_stream (struct kunit *test );
β¨ ARGUMENTS β¨
testβ the KUnit test context π§ that's the one and only thing it takes, and it's literally the standard KUnit test context, no cap.
π DESCRIPTION π
so the whole point, bestie: amdgpu_dm_link_setup_replay should return false when no stream is provided π like, no stream = no setup, that's the whole test. it's a NULL-rejection vibe check and it ate π₯
