dm_test_crt...urce_invalid(9)

okay bestie, welcome to the dm_test_crtc_set_crc_source_invalid(9) page from the Kernel API Manual ✨ (the running header/footer is out here truncating it as dm_test_crt...urce_invalid(9), iconic honestly).

💖 NAME 💖

dm_test_crtc_set_crc_source_invalid — Test invalid source guard. 💅

✨ SYNOPSIS ✨

void dm_test_crtc_set_crc_source_invalid (struct kunit *test );

🧪 ARGUMENTS 🧪

• test — KUnit test context.

🔍 DESCRIPTION 🔍

This one verifies that amdgpu_dm_crtc_set_crc_source rejects invalid source names before taking modeset locks, vblank references, or touching DC state. Like, the invalid-source guard is doing its thing first — no cap, that’s the whole vibe check 🫶
