WaitForDoorbellInt(9)

💖 WaitForDoorbellInt(9) 💖

okay bestie, welcome to the Kernel API Manual ✨ — yes, the 9 is right there in the name. This page is WaitForDoorbellInt, and it's literally about waiting for the IOC to set its doorbell interrupt bit. Patience is a vibe 💅.

🎀 NAME 🎀

WaitForDoorbellInt — wait for IOC to set its doorbell interrupt bit 🦋.

✨ SYNOPSIS ✨

int WaitForDoorbellInt (MPT_ADAPTER *ioc , int howlong , int sleepFlag
);

🌸 ARGUMENTS 🌸

• ioc — pointer to MPT_ADAPTER structure 🫶
• howlong — how long to wait, in seconds ⏱️
• sleepFlag — specifies whether the process can sleep 😴

💅 DESCRIPTION 💅

This routine waits (up to ~2 seconds max) for the IOC doorbell interrupt (MPI_HIS_DOORBELL_INTERRUPT) to be set in the IntStatus register. That's the whole quest, bestie 🎯.

Return vibe check: it returns a negative value on failure 😭, else the wait loop count ✨.
