💅 dm_test_han...nce_schedule(9) 💅

okay so bestie, welcome to the Kernel API Manual page for dm_test_handle_hpd_irq_helper_debounce_schedule. It’s giving very specific KUnit test energy, and honestly? iconic. Let’s go 🫶

🌸 NAME 🌸

dm_test_handle_hpd_irq_helper_debounce_schedule — Test HDMI debounce branch. That’s the whole plot, no cap.

✨ SYNOPSIS ✨

void dm_test_handle_hpd_irq_helper_debounce_schedule (struct kunit *test
);

🎀 ARGUMENTS 🎀

  • test — The KUnit test context. Like, the little test bubble this function lives in 💖

🦋 DESCRIPTION 🦋

Okay so picture this: an HDMI link is reporting a disconnect — that’s connection type none — and there’s a non-zero debounce delay plus a cached local_sink. This test is checking that the code absolutely must take the debounce branch: the way that it caches local_sink in hdmi_prev_sink and schedules the delayed debounce work instead of detecting immediately. That’s the vibe check, and this test is obsessed with making sure it passes, fr fr.
