dm_test_cre...sink_no_edid(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dm_test_cre...sink_no_edid(9) — Kernel API Manual, section 9, bestie ✨

okay so this is dm_test_create_eml_sink_no_edid(9) from the Kernel API Manual (section 9, the kernel-girlies section, iykyk), and honestly? it's a little icon. it's a KUnit test that checks the no-EDID branch and confirms it creates, like, absolutely no sink. zero. nada. not one emulated sink 🎀

✨ NAME ✨

dm_test_create_eml_sink_no_edid — literally just testing that the no-EDID branch creates no sink 🦋

🌸 SYNOPSIS 🌸

void dm_test_create_eml_sink_no_edid (struct kunit *test );

🍓 ARGUMENTS 🍓

  • test — The KUnit test context 💖 this is the lil test bubble everything gets reported into, no cap

🧚 DESCRIPTION 🧚

so here's the vibe: when no EDID can be read, the function logs an error and returns without allocating an emulated sink. that's it, that's the whole test. it's giving "we tried to get the display's selfie and it ghosted us, so we're not making a fake one" 😭

the branch is: no EDID readable → log an error → bail out → no emulated sink gets allocated. our girl is just making sure that bail-out actually bails and doesn't sneak an emulated sink into existence behind everyone's back 💀
