π©΅ dm_test_rn_get_dpm_clock_table_ok β NAME π©΅
okay so this is dm_test_rn_get_dpm_clock_table_ok(9), straight out of the Kernel API Manual bestie, and it's literally the test that checks the DPM clock table comes back okay. the vibe? "did the success path actually succeed." iconic honestly π
β¨ SYNOPSIS β¨
void dm_test_rn_get_dpm_clock_table_ok (struct kunit *test );
that's it. that's the whole signature. no cap π«Ά
π ARGUMENTS π
testβ the KUnit test context, aka the little group-chat the test lives in. she's the main character here, she carries all the test state π
πΈ DESCRIPTION πΈ
so what does this actually do? bestie, it's a vibe check on the success path: it verifies that pp_rn_get_dpm_clock_table returns PP_SMU_RESULT_OK when everything goes right. that's the whole assignment. the function said "yes" and this test is here to make sure it meant it. slay β
like, no edge cases, no drama, no "but what if it fails" β that's a different test, iykyk. this one is purely: happy path, happy result, PP_SMU_RESULT_OK, periodt π₯
ngl this is one of the chillest tests in the whole file β the ones where stuff goes sideways get their own manpages, so don't come for her π
