2024-10-18 Thread Naman Jain
After VM requests for channel offers during boot or resume from hibernation, host offers the available channels and then sends a separate message when all offers are delivered. Wait for this message to make this offers request and receipt process synchronous. This is to support user mode (VTL0) in

This is to support user mode (VTL0) in OpenHCL (A Linux based paravisor for Confidential VMs) t
