dm_test_dcn1...ers_one_crtc(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, sit down, we're doing kernel docs 💅 this one's straight out of the Kernel API Manual — it's dm_test_dcn1...ers_one_crtc(9) (yes the title got cut off, no it's not my fault, love that for us ✨). it's a KUnit test page, it's iconic, it's small, let's go 🦋

✨ NAME ✨

dm_test_dcn10_register_irq_handlers_one_crtc — literally "Test DCN10 with 1 CRTC". that's the whole thing. one CRTC. test it. slay 🎀

✨ SYNOPSIS ✨

void dm_test_dcn10_register_irq_handlers_one_crtc (struct kunit *test );

✨ ARGUMENTS ✨

  • test — the KUnit test context 💖 like, the lil sandbox the test lives in. that's it. that's the only arg.

✨ DESCRIPTION ✨

so what does it actually do 🧐? it exercises the VUPDATE_NO_LOCK for-loop bodies using a fake IRQ service (yes queen, a fake one, we're not touching real hardware today 🙈), and then it checks that VUPDATE_NO_LOCK is the only one that's populated — other than VLINE0, which is there for secure display 🔥. that's the vibe check, and it ate.

✨ SEE ALSO ✨
