[Qemu-discuss] ACPI shutdown no longer works after upgrading to QEMU 2.1.2

[Alexander Miller]

Hi,

I am running Pintos in QEMU. Today I upgraded from QEMU 1.6.2 to 2.1.2 and found out that the ACPI shutdown sequence no longer works:

  /* ACPI Shutdown sequence supported by Bochs and QEMU

      http://forum.osdev.org/viewtopic.php?t=16990  */

  outw( 0xB004, 0x0 | 0x2000 );

What has changed in QEMU?

Thank you for your help,

Alex
