fh_send_nmi(9)

💅 fh_send_nmi(9) 💅

okay bestie, welcome to the Kernel API Manual page for fh_send_nmi(9) — we're doing hypervisor calls and honestly it's giving tiny-but-mighty. Let's go ✨

✨ NAME ✨

fh_send_nmi — send NMI to virtual cpu(s).

🌸 SYNOPSIS 🌸

unsigned int fh_send_nmi (unsigned int vcpu_mask );

🎀 ARGUMENTS 🎀

• vcpu_mask — the mask that says which virtual cpu(s) are getting the NMI: send NMI to virtual cpu(s) specified by this mask. 💌

🦋 DESCRIPTION 🦋

This one is lowkey simple, bestie: it returns 0 for success, or EINVAL for an invalid vcpu_mask. That's the whole vibe check. ✅
