dm_mst_test...onnector_edp(9)

🌸 NAME 🌸

okay so bestie, this is the manual page dm_mst_test...onnector_edp(9) from the Kernel API Manual, and it's all about dm_mst_test_initialize_dp_connector_edp — literally “Test eDP initialization path.” No cap. 🫶

✨ SYNOPSIS ✨

void dm_mst_test_initialize_dp_connector_edp (struct kunit *test );

That's the signature, character-for-character. It returns void, and it takes the KUnit context. 💅

🎀 ARGUMENTS 🎀

• test — KUnit test context. That's the one thing you pass in, and it's literally the test's context. 🧚

🦋 DESCRIPTION 🦋

The tea ☕: this test verifies that amdgpu_dm_initialize_dp_connector initializes the DP AUX state and exits before MST topology setup for eDP connectors. That's the whole vibe check — DP AUX state gets initialized, and it exits before MST topology setup when it's an eDP connector. It's giving “verify the AUX state and the early exit,” bestie. ✨
