💅 ih_v6_1_irq_rearm(9) — from the Kernel API Manual

okay so bestie, picture this: you're deep in the AMDGPU interrupt handler, the IRQ got lost somewhere in the void, and nobody's answering. this page is literally the "hey, u up? pls try again" function for exactly that situation. it's giving customer-service energy for interrupts. 🎀

✨ NAME ✨

ih_v6_1_irq_rearm — rearm IRQ if lost 💖

like, if the interrupt went missing, this is the little nudge that gets it back on its feet.

🦋 SYNOPSIS 🦋

void ih_v6_1_irq_rearm (struct amdgpu_device *adev , struct
       amdgpu_ih_ring *ih );

returns void, so don't go looking for a return value, there isn't one, periodt.

🌸 ARGUMENTS 🌸

• adev — amdgpu_device pointer 🔥 your ticket to the whole device, the main character of the AMDGPU world.
• ih — amdgpu_ih_ring pointer 👑 the specific interrupt handler ring we're talking about here.

ngl, if you're calling this you probably already suspect the IRQ ghosted you. rearm, recheck, and move on 💀

and that's a wrap, bestie! 🧚 this page came from ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and it lives in the Kernel API Manual — go forth and keep those interrupts from getting lost 💜✨
