✨ dm_test_default_clock_levels_memory(9) ✨

okay so real talk, this page lives in the Kernel API Manual and it's about dm_test_default_clock_levels_memory — a KUnit test that checks the memory clock default levels. yes bestie, there are several of these and the display one and engine one get their own pages too, we'll get to them 💅

🌸 NAME 🌸

dm_test_default_clock_levels_memory — Test memory clock default levels. that's it, that's the whole job, and honestly? iconic.

🎀 SYNOPSIS 🎀

void dm_test_default_clock_levels_memory (struct kunit *test );

no return value, it's a void girlie, she just is 🫶

🦋 ARGUMENTS 🦋

  • test — the KUnit test context. yeah she needs her little test harness bestie to run, don't we all 😭

💖 DESCRIPTION 💖

okay so here's the vibe check: this test verifies that get_default_clock_levels populates 2 memory clock levels, and that those levels have the expected frequencies in kHz. that's the whole assertion. two levels, right frequencies, in kHz, no cap 🎯

like, it's a "did the function do the thing it says it does" test and honestly we love a queen who knows her own spec ✨
