[Qemu-discuss] QEMU needs the reset when waking up from sleep.

[추헌광]

Hi all, 
 
From below git.qemu.org website, I saw that QEMU is basically using reset logic 
when waking up from S3.

Could you explain why the reset is needed when QEMU wakeup from sleep ?
Is it just some concept like promise for QEMU?
 
+    if (qemu_wakeup_requested()) {+        pause_all_vcpus();+        
cpu_synchronize_all_states();+        qemu_system_reset(VMRESET_SILENT);+       
 resume_all_vcpus();+    }
I appreciate it very much!
