cik_irq_ack(9)

👑 cik_irq_ack(9) — Kernel API Manual 👑

🌸 NAME 🌸

cik_irq_ack — ack interrupt sources 💅

✨ SYNOPSIS ✨

okay so the signature is literally this, bestie:

void cik_irq_ack (struct radeon_device *rdev );

💖 ARGUMENTS 💖

• rdev — radeon_device pointer 🫶

🦋 DESCRIPTION 🦋

This is the function that acks interrupt sources on the GPU — vblanks, hpd, etc. — for CIK. ✨

Certain interrupt sources are sw generated and do not require an explicit ack. No cap, that part is just how it is.

🌈 SEE ALSO 🌈
