💅 NAME 💅

dm_test_notify_wm_clock_changes_non_polaris — Test non-Polaris path.

Okay bestie, welcome to the dm_test_not..._non_polaris(9) page in the Kernel API Manual. This is the tiny-but-focused KUnit test for the non-Polaris path, and it's literally right there in the name. No cap. 🎀

✨ SYNOPSIS ✨

void dm_test_notify_wm_clock_changes_non_polaris (struct kunit *test );

Copy that exactly, spacing and all. The vibes are specific. 🫶

🎀 ARGUMENTS 🎀

• test — KUnit test context. It's the test's little VIP pass, fr fr.

🦋 DESCRIPTION 🦋

Verify dm_pp_notify_wm_clock_changes returns false for non-Polaris ASICs.

That's the whole assignment: non-Polaris ASIC case, and dm_pp_notify_wm_clock_changes is expected to return false. The test is holding the clipboard and doing the vibe check. 💖
