💅 ih_v7_0_irq_rearm — a little page from the Kernel API Manual, section 9 🎀

okay so bestie, welcome to the group chat for kernel API pages ✨ this one's from the Kernel API Manual, section 9, and it's about a tiny little function with a big job: putting an IRQ back on its feet when it gets lost. yes, lost. like your AirPods. except this one is fixable 🫶

✨ NAME ✨

ih_v7_0_irq_rearm — rearm IRQ if lost 💖

like, literally that's the whole vibe. if the interrupt got dropped somewhere, this re-arms it. no cap.

---

🌸 SYNOPSIS 🌸

void ih_v7_0_irq_rearm (struct amdgpu_device *adev , struct
       amdgpu_ih_ring *ih );

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

---

🦋 ARGUMENTS 🦋

• adev — amdgpu_device pointer. yep, the classic. the device, the main character 👑
• ih — IH ring to match. THIS is the specific ring we're matching, so like, know which one you're talking about before you show up 🙈
