💅 vega20_ih_irq_rearm(9) — from the Kernel API Manual, bestie

okay so picture this: it's a kernel API manual, section 9, and this lil function is the one that goes "hey bestie, you good?" and re-arms the IRQ if it got dropped. that's the whole vibe. genuinely iconic of it.

✨ NAME ✨

vega20_ih_irq_rearm — rearm IRQ if lost 🫶

like, if the interrupt went missing (it happens, we don't judge), this is the one that picks it back up and puts it back on its feet. no cap.

---

🌸 SYNOPSIS 🌸

void vega20_ih_irq_rearm (struct amdgpu_device *adev , struct
       amdgpu_ih_ring *ih );

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

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer 💖 literally the whole GPU device situation, she's the main character here.
• ih — an amdgpu_ih_ring pointer ✨ the interrupt handler ring in question, the one we're checking on and possibly re-arming. iykyk.
