💅 dm_test_dce110_register_irq_handlers_one_crtc — Kernel API Manual ✨

okay so bestie, welcome to the ✨ Kernel API Manual ✨, and today's main character is dm_test_dce110_register_irq_handlers_one_crtc(9). yes the header line is out here lookin' like dm_test_dce...ers_one_crtc(9) because someone let the truncation gremlins cook 😭 but we know her full name, and she's serving full-name energy. 🎀

🦋 NAME 🦋

dm_test_dce110_register_irq_handlers_one_crtc — literally "Test DCE110 with 1 CRTC". that's it. that's the whole vibe check. one CRTC, DCE110, irq handlers registered. slay. 💅

🌸 SYNOPSIS 🌸

void dm_test_dce110_register_irq_handlers_one_crtc (struct kunit *test
);

notice how she takes exactly one thing and returns void? lowkey iconic. no notes. 🫶

⭐ ARGUMENTS ⭐

  • test — the KUnit test context, bestie. that's the whole argument list, we're traveling light today ✈️✨

🔥 DESCRIPTION 🔥

okay so this test is out here exercising the VBLANK, VUPDATE, PFLIP and HPD for-loop bodies. yes, all four of them, no cap. and how does she do it? with a fake IRQ service that maps source IDs to DC IRQ sources — a little pretend-IRQ situation, a simulation, a stunt double for interrupts 🎭

she runs those loop bodies with that fake service and makes sure everything lines up. it's giving "controlled environment", it's giving "unit test", it's giving "we're not touching real hardware today, babes". 💀✨

🌈 SEE ALSO 🌈

the kernel file, first of all:

and then… the whole extended friend group. yes, there are SO many and we're listing every single one, because nobody gets left behind in this group chat 💖

like… that's the whole roster 😭 everyone showed up to the party 🎉 and honestly? we love a comprehensive SEE ALSO section. iykyk. 💜

🫶 friendly reminder bestie: this whole page came out of ./drivers/gpu/drm/amd/display/... and it's dated October 2026 — so keep that energy in mind when you're citing her. mwah. 💋

and that's the page, babes — go forth and register those irq handlers with exactly one CRTC. periodt. 👑✨
