alloc_test_ddc_link(9)

📦 version 7.3.1, in nixpkgs unstable

okay so, welcome to the Kernel API Manual page for alloc_test_ddc_link(9), bestie. This is the test-support helper that’s lowkey iconic: it wires up the fake DDC link vibe so the KUnit girlies can do their thing. 🎀

🎀 NAME 🎀

alloc_test_ddc_link — connector/link wired to the recording i2c + aux fakes. It’s giving test scaffolding main character energy, no cap. ✨

🌸 SYNOPSIS 🌸

struct dc_link * alloc_test_ddc_link (struct kunit *test );

🦋 ARGUMENTS 🦋

  • test — KUnit test context for managed allocation. This is the test bestie that keeps the allocation situation managed. 🫶

💜 DESCRIPTION 💜

okay so, what does it actually do? Builds an amdgpu_dm_connector with a fake i2c adapter and a fake DP aux, and points link->priv at the connector so dm_helpers_* find it. Then it returns the dc_link that the lp_* wrappers take as their opaque handle. Slay. 💅

Bestie, this is the kind of helper that makes the fake stuff feel real enough for tests. Cute, iconic, necessary. 🧚
