🌸 mtk_intx_eoi(9) — Kernel API Manual realness 🌸

okay bestie, welcome to mtk_intx_eoi(9) from the Kernel API Manual — short page, clear job, very “handle it at the end” energy 💅✨

💖 NAME 💖

mtk_intx_eoi — Clear INTx IRQ status at the end of interrupt 🎀

✨ SYNOPSIS ✨

void mtk_intx_eoi (struct irq_data *data );

🫶 ARGUMENTS 🫶

• data — pointer to chip specific data ✨

💅 DESCRIPTION 💅

As an emulated level IRQ, its interrupt status will remain until the corresponding de-assert message is received; hence that the status can only be cleared when the interrupt has been serviced. No cap, that’s the whole vibe — the status is literally waiting for its de-assert message before it can be cleared, and clearing only happens once the interrupt has actually been serviced 🦋
