dm_test_irq...patches_work(9)

📦 version 7.3.1, in nixpkgs unstable

💅 dm_test_irq_handler_dispatches_work — like, the whole vibe check on the top-level IRQ handler

okay bestie, so this one lives in the Kernel API Manual, section 9. Sit down, hydrate, and let's get into it 🫶

✨ NAME ✨

dm_test_irq_handler_dispatches_work — literally the test for the top-level IRQ handler 💅

🌸 SYNOPSIS 🌸

void dm_test_irq_handler_dispatches_work (struct kunit *test );

🎀 ARGUMENTS 🎀

  • test — the KUnit test context. that's it, that's the whole argument. she's low-maintenance 👑

🦋 DESCRIPTION 🦋

okay so picture this: amdgpu_dm_irq_handler is out here doing the most — it takes the hardware IRQ entry, translates it into a DC IRQ source, acknowledges it, and then dispatches it out to both the high-context (immediate) handler list and the low-context (scheduled) handler list. multi-tasking icon behavior, honestly ✨

and the test? it sets up a fake dc with a stubbed irq_service that maps the source id to DC_IRQ_SOURCE_VBLANK1, and lets the ack succeed without ever touching hardware registers. no cap, no real silicon was harmed in the making of this test 🧚💜
