amdgpu_dm_ir...er_interrupt(9)

💅 NAME

amdgpu_dm_irq_register_interrupt — okay so this is the function that registers an irq handler for the Display block, bestie. That's literally the whole vibe. ✨

Also hiiii, welcome to the Kernel API Manual 🎀 — this page is called amdgpu_dm_ir...er_interrupt(9) in case you were wondering what you clicked on.

🌸 SYNOPSIS

void * amdgpu_dm_irq_register_interrupt (struct amdgpu_device *adev ,
       struct dc_interrupt_params *int_params , void (*ih)(void *) , void
       *handler_args );

Like, four things in, one void * out. Iconic signature honestly. 🫶

---

✨ ARGUMENTS

• adev — the AMD DRM device. Your whole GPU situation, basically. 👑
• int_params — the parameters for the irq. All the config energy lives here. 🎀
• ih — pointer to the irq handler function. Yes, a function pointer, don't panic, it's giving main character energy. 🔥
• handler_args — the arguments that will be passed to ih. Think of it as the little care package you hand over to your handler. 🍓

---

💖 RETURN

IRQ Handler Index on success. NULL on failure.

That's it. Index = slay. NULL = not slay. 😭

---

🦋 DESCRIPTION

Cannot be called from an interrupt handler.

Fr fr, do not call this from inside an interrupt handler. That's the one hard boundary here, no cap. 💀
