dm_test_set_irq_funcs(9)

✨ dm_test_set_irq_funcs(9) — the Kernel API Manual page, but make it make sense ✨

okay so bestie, welcome to section 9 of the Kernel API Manual 💅 this is the page for dm_test_set_irq_funcs, and no cap it's a tiny one — like, one function, one argument, one whole vibe. but the SEE ALSO section? absolutely unhinged 🫶 so buckle up, we're doing all of it.

---

🌸 NAME 🌸

dm_test_set_irq_funcs — literally just checks that the irq src funcs and the counts are actually populated. that's the whole job. it's giving "tiny test, big responsibility" 👑

---

🎀 SYNOPSIS 🎀

void dm_test_set_irq_funcs(struct kunit *test);

that's it. that's the whole signature. she's short, she's sweet, she's void 💖

---

🦋 ARGUMENTS 🦋

• test — the KUnit test context, aka the little environment the test runs inside. you hand her the context, she does her thing. no context, no test, periodt ✨

---

🔥 SEE ALSO 🔥

okay so first things first, the source of truth lives in this kernel file:

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

and now... the list. the iconic, the legendary, the genuinely-quite-long list of sibling tests. every single one, exactly as written, because we do not skip entries in this house 😤💅

aaaand that's the page!! short test, chaotic see-also, absolutely ate. this cutie came from the kernel source tree at ./drivers/gpu/drm/amd/display/..., dated October 2026, and the whole thing lives under the dm_test_set_irq_funcs(9) name in the Kernel API Manual. mwah 💋✨
