✨ dm_test_hdmi_hpd_debounce_reallow_idle(9) ✨

okay bestie, welcome to the Kernel API Manual, section (9) — the header shorthand for this one is dm_test_hdmi...reallow_idle(9), and we are so here for it 🫶.

🌸 NAME 🌸

dm_test_hdmi_hpd_debounce_reallow_idle — Test debounce idle/sink-release tail. no cap, that's the whole vibe 💅

🦋 SYNOPSIS 🦋

void dm_test_hdmi_hpd_debounce_reallow_idle (struct kunit *test );

💅 ARGUMENTS 💅

  • test — the KUnit test context. literally the little test-context bestie this whole thing runs inside 🫶

🎀 DESCRIPTION 🎀

okay so picture this: detection is stubbed to return false, so the if (ret) block gets skipped — but the function tail still gets fully exercised, periodt. IPS support plus an idle-allowed dmub makes reallow_idle true, so dc_allow_idle_optimizations runs on both entry and exit (disable_idle_power_optimizations keeps those safe early returns, no cap), and a cached hdmi_prev_sink gets released and cleared. it's giving cleanup slay 💅✨
