kvm_s390_pv_make_secure(9)

💖 NAME 💖

okay so bestie, this page is kvm_s390_pv_make_secure(9) from the Kernel API Manual, and it does one iconic thing: make one guest page secure. That’s the whole vibe. 🔥

✨ SYNOPSIS ✨

int kvm_s390_pv_make_secure (struct kvm *kvm , unsigned long gaddr ,
       void *uvcb );

🎀 ARGUMENTS 🎀

• kvm — the guest. Like, the whole VM we’re doing this for. 🫶
• gaddr — the guest address that needs to be made secure. This is the exact spot getting the secure treatment. ✨
• uvcb — the UVCB specifying which operation needs to be performed. It’s the instruction card for the operation. 💅

🦋 CONTEXT 🦋

Bestie, important: this needs to be called with kvm->srcu held. No cap, that’s the rule. 🔒

🌸 RETURN 🌸

0 on success, < 0 in case of error. That’s it — slay when zero, error when negative. 😭
