🌸 dm_test_rv_s...sleep_dcfclk(9) — Kernel API Manual ✨

okay so bestie, welcome to the glow-up edition of the dm_test_rv_s...sleep_dcfclk(9) page from the Kernel API Manual 💅 this one's a tiny little KUnit test with a huge friend group, and we're gonna get into all of it, no cap 🫶

💖 NAME 💖

dm_test_rv_set_min_deep_sleep_dcfclk — literally just here to Test Raven deep sleep clock 🕰️✨

🦋 SYNOPSIS 🦋

void dm_test_rv_set_min_deep_sleep_dcfclk (struct kunit *test );

that's it. that's the whole signature. short king behavior 👑 (copy it exactly tho, fr fr)

🎀 ARGUMENTS 🎀

  • test — the KUnit test context 🧪✨ it's giving "backstage pass to the test framework," and yeah, it's the only thing this function wants from you.

💅 DESCRIPTION 💅

so what does this icon actually do? it runs a verification that pp_rv_set_min_deep_sleep_dcfclk forwards the clock value to DPM — and does it without crashing 😭🔥

that's the whole vibe check: does the value make it over to DPM, and does the machine stay alive while it happens. no extra drama, no surprises, just a clean pass. periodt 💀✨

no cap: the only thing being asserted here is the forwarding + not-crashing combo. don't go reading extra behavior into it 🙈
