💅 dm_test_han...release_prev(9) 🎀

okay so this page is from the Kernel API Manual, and it's giving “tiny test, very specific job, main character energy.” No cap, bestie — let's get into it.

💖 NAME 💖

dm_test_handle_hpd_irq_helper_debounce_release_prev — test stale prev_sink.

✨ SYNOPSIS ✨

void dm_test_handle_hpd_irq_helper_debounce_release_prev (struct kunit
*test );

🎀 ARGUMENTS 🎀

  • test — the KUnit test context. That's the vibe check holder for this test, fr fr.

🦋 DESCRIPTION 🦋

So here's the tea: when the debounce branch is taken, and a stale hdmi_prev_sink is already cached from a previous HPD, it must be released before caching the current local_sink. That's the whole moment.

This test exercises the dc_sink_release of the previous sink. Iconic cleanup behavior, honestly. 🫶
