kvmppc_gsb_recv(9)

🌸 NAME 🌸

okay bestie, welcome to kvmppc_gsb_recv(9) from the Kernel API Manual 💖 This one is kvmppc_gsb_recv — request all elements in the buffer have their value updated. That’s the whole assignment, no cap ✨

✨ SYNOPSIS ✨

int kvmppc_gsb_recv (struct kvmppc_gs_buff *gsb , unsigned long flags );

🎀 ARGUMENTS 🎀

• gsb — guest state buffer 🫶
• flags — guest wide or thread wide 💅

🦋 DESCRIPTION 🦋

So here’s the vibe: it performs the H_GUEST_GET_STATE hcall for the guest state buffer. Then, after returning from the hcall, the guest state elements that were present in the buffer will have updated values from the hypervisor. Hypervisor said “fresh values, bestie” and honestly? Iconic ✨
