vega20_ih_irq_init(9)

💖 NAME 💖

okay so bestie, this page is from the Kernel API Manual and the main character is vega20_ih_irq_init(9). 🫶

vega20_ih_irq_init — init and enable the interrupt ring. periodt. ✨

✨ SYNOPSIS ✨

int vega20_ih_irq_init (struct amdgpu_device *adev );

That signature is giving exact, no cap. 🎀

🎀 ARGUMENTS 🎀

• adev — amdgpu_device pointer. literally the device pointer, bestie. 🦋

🦋 DESCRIPTION 🦋

So the vibe is: it allocates a ring buffer for the interrupt controller, enables the RLC, disables interrupts, enables the IH ring buffer, and enables it (VI). 💅

Called at device load and reume. (Yep, reume is exactly what the page says — I'm not fixing it, fr fr.) 😭

Returns 0 for success, errors for failure. That's the return tea, periodt. 🌸
