💅 dm_test_crtc..._crc_sources(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes we're reading kernel docs together, it's giving study date energy 🫶. This one's about dm_test_crtc_get_crc_sources, and honestly? She's a vibe check for CRC sources. Let's get into it ✨

🌸 NAME 🌸

dm_test_crtc_get_crc_sources — the test that checks which CRC source strings are actually available. literally just verifying the list, no cap.

🎀 SYNOPSIS 🎀

void dm_test_crtc_get_crc_sources (struct kunit *test );

that's it. one function, one arg, no drama 💀

🦋 ARGUMENTS 🦋

  • test — the KUnit test context. she's the main character handing you everything the test needs, you don't gotta worry about her 💖

✨ DESCRIPTION ✨

so here's the tea ☕: this test verifies that amdgpu_dm_crtc_get_crc_sources returns the static source list — like, the actual list it's supposed to return, no impostors allowed 💅 — and it also reports all debugfs source names. so basically it's double-checking that the sources are right AND that every debugfs name actually gets reported. iconic behaviour, truly 👑
