dm_test_nat...zeroes_clock(9)

📦 version 7.3.1, in nixpkgs unstable

Hey bestie 💖 welcome to the dm_test_nat...zeroes_clock(9) page — that's the Kernel API Manual, and the full icon name is dm_test_native_mode_empty_probed_zeroes_clock. No cap, this one is a tiny little KUnit test. Let's go. 🎀

🌸 NAME 🌸

dm_test_native_mode_empty_probed_zeroes_clock — Test empty probed list clears mode. She's literally the main character of this page. 💅

✨ SYNOPSIS ✨

The whole signature is giving one-liner energy:

void dm_test_native_mode_empty_probed_zeroes_clock (struct kunit *test
);

That's it. That's the function. 🫶

🫶 ARGUMENTS 🫶

Only one argument, bestie:

  • test — The KUnit test context. Iconic. ✨

💅 DESCRIPTION 💅

Okay so picture this: there are no probed modes. That means there's no preferred mode to copy, so the encoder's native mode is memset to zero — which makes the clock become 0. Periodt. 💀

🔥 SEE ALSO 🔥

Kernel file: ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_connector_test.c — that's where the lore lives. 📁

And the whole test-suite group chat, all invited:

Cute sign-off: source/version line is ./drivers/gpu/drm/amd/display/..., dated October 2026, and the manual tag is dm_test_nat...zeroes_clock(9). Mwah 💋💖
