dm_test_nv_s..._unsupported(9)

💅 NAME

okay so bestie, this is dm_test_nv_set_min_deep_sleep_dcfclk_unsupported — it's a little test that checks the EOPNOTSUPP mapping slays correctly ✨

🎀 SYNOPSIS

void dm_test_nv_set_min_deep_sleep_dcfclk_unsupported (struct kunit
*test );

🦋 ARGUMENTS

• test — the KUnit test context, aka the little group chat where all the test results get posted 🫶

🌸 DESCRIPTION

so the whole vibe here is: we call pp_nv_set_min_deep_sleep_dcfclk and we verify it returns PP_SMU_RESULT_UNSUPPORTED. that's it. that's the test. it's giving "unsupported, and we're at peace with that" 💀 and ngl, it passes — iconic behavior fr fr 👑
