dm_test_rn_...k_table_fail(9)

💅 NAME

Okay so bestie, welcome to the Kernel API Manual (section 9, periodt) — this page is dm_test_rn_...k_table_fail(9) up in the header, and its actual full name is dm_test_rn_get_dpm_clock_table_fail: the test that checks generic error mapping. It's giving very specific, very focused, very "one job and she does it" energy. 🎀

---

✨ SYNOPSIS

void dm_test_rn_get_dpm_clock_table_fail (struct kunit *test );

---

🫶 ARGUMENTS

• test — the KUnit test context. That's it, that's the whole arg list, and honestly? Iconic of her. 💅

---

🔥 DESCRIPTION

So here's the vibe: this test verifies that pp_rn_get_dpm_clock_table returns PP_SMU_RESULT_FAIL. That's the entire character arc. No cap — a fail case getting its own fail-check, which is exactly the kind of self-aware energy we stan. The way that error path gets tested too? Obsessed. 💖

🦋 That's the whole page bestie — go read the source file if you want the deep lore, ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_pp_smu_test.c has it all iykyk.

Sign-off time ✨: this lil page comes from the ./drivers/gpu/drm/amd/display/... source, dated October 2026, and it lives under dm_test_rn_...k_table_fail(9) in the Kernel API Manual. Mwah 💋 — now go write some passing tests, main character. 👑
