🌸 dm_test_dmub_outbox1_low_irq_offload(9) 🌸

okay bestie, welcome to the Kernel API Manual ✨ this one's a KUnit test page and it's honestly kinda short but we're gonna give it the full main-character treatment anyway 💅

💖 NAME 💖

dm_test_dmub_outbox1_low_irq_offload — the test that checks offloaded callback dispatch 🎀

🦋 SYNOPSIS 🦋

void dm_test_dmub_outbox1_low_irq_offload (struct kunit *test );

🫶 ARGUMENTS 🫶

  • test — the KUnit test context 🧚 that's it, that's the whole argument list, she's low maintenance

✨ DESCRIPTION ✨

okay so here's the vibe: notifications get enabled 💖 with a callback that's all registered and cozy, and thread offload is switched on too — which means that callback doesn't just fire off right there and then, nope, she gets dispatched via the delayed HPD work queue 🌀 and that is literally the whole thing this test is checking.

ngl it's giving "small test, big responsibility" energy 👑

🌈 SEE ALSO 🌈

and that's the page bestie!! 🎀 sign-off time: this cutie came from the source/version line ./drivers/gpu/drm/amd/display/... and she's dated October 2026 ✨ go forth and test those offloaded callbacks, ily, bye 👑💖🦋
