dm_test_han...irq_disabled(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dm_test_han...irq_disabled(9) — the Kernel API Manual page, but make it make sense

okay so bestie, welcome to the glow-up of dm_test_han...irq_disabled(9), straight out of the Kernel API Manual ✨. it's a tiny page, but it's iconic in its own little way, and i'm gonna walk you through every crumb of it. no skips, no vibe-based guessing 🫶

✨ NAME ✨

dm_test_handle_hpd_irq_disabled — literally the test that checks the HPD helper bails out correctly when the whole thing is disabled 💅

like, that's the whole job. the helper gets called while disabled, and this test is the one holding up a little sign going "bestie, you should have returned by now" 🎀

🌸 SYNOPSIS 🌸

void dm_test_handle_hpd_irq_disabled (struct kunit *test );

that's it. that's the whole signature. a void return, one parameter, very demure, very mindful 🦋. it doesn't hand anything back — it just runs the test and dips ✌️

🦋 ARGUMENTS 🦋

  • test — the KUnit test context 💖. this is the little bundle of test scaffolding that KUnit hands over so the test knows what it's doing and where to report. it's the main character of this function's parameter list, seeing as it's the only one 👑

🔥 SEE ALSO 🔥

first up, the file this whole thing lives in — the Kernel file:

./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_irq_test.c

and now, the guest list 🎀 — every single one of these has its own page in section 9, and i'm not dropping a single name, because everybody gets their moment:

no cap, that is the entire see-also list, all 125 of them, in the exact order the page gives them 💯 do not come for me about the count, i counted twice 🧚

and that's the whole page, bestie — short, sweet, and lowkey a little legend 👑. this one's sourced from ./drivers/gpu/drm/amd/display/..., dated October 2026, so go forth and test those disabled IRQ paths with main character energy 🌈💜 periodt ✨
