dm_test_dmu...q_no_handler(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME

okay so first things first, the manual is the Kernel API Manual, section 9, and the star of this page is dm_test_dmub_outbox1_low_irq_no_handler — a test that checks what happens when a notification shows up and literally nobody is registered to handle it. ✨

🦋 SYNOPSIS

void dm_test_dmub_outbox1_low_irq_no_handler (struct kunit *test );

🎀 ARGUMENTS

  • test — the KUnit test context. it's the lil' test-world-in-a-box that KUnit hands over so the test has somewhere to live 🫶

🌸 DESCRIPTION

so here's the vibe 💅 notifications get enabled, right? but then — plot twist — no callback is registered for the notification type that gets returned. and the whole point is to exercise that skip-with-warning path. it's giving "we sent the invite and nobody RSVP'd, so we log it and move on" 😭✨

🌈 SEE ALSO

okay that's literally all of them, every single one, no cap 👑 and that's the whole page bestie 🫶
