[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!
