mpi3mr_unmask_events(9)

💅 mpi3mr_unmask_events(9) — straight from the Kernel API Manual, bestie 💅

Okay so we're in the Kernel API Manual and this page is mpi3mr_unmask_events(9). It's giving “tiny function, very important bit-flipping behavior,” and I'm obsessed. 🎀

🌸 NAME 🌸

mpi3mr_unmask_events — unmask events in the event mask bitmap. Periodt. ✨

✨ SYNOPSIS ✨

void mpi3mr_unmask_events (struct mpi3mr_ioc *mrioc , u16 event );

🫶 ARGUMENTS 🫶

• mrioc — the adapter instance reference. That's your main-character adapter, iykyk. 💖
• event — the MPI event ID. The specific event we're unmasking, no cap. 🌈

🧚 DESCRIPTION 🧚

This one unmasks the specific event by resetting the event_mask bitmap. That's the vibe: specific event, event_mask bitmap reset, mask comes off. Slay. 💅

😭 RETURN 😭

0 on success, non-zero on failures. The docs said it, I'm just relaying it fr fr. 💀
