[Qemu-devel] [PATCH V8 0/3] Virtual Machine Generation ID

[Gal Hammer]

Hi,

The patch grow to three parts now. Although it is still add a QEmu
support for Microsoft's Virtual Machine Generation ID device.

The first is a short device's description, then the ACPI tables
changes and the actual device and the last patch updates the tests'
ACPI tables.

Your comment are welcomed.

Thanks,

    Gal.

V8 - Add a device's description file.
   - GUID is stored in fw cfg file and the guest writes the
     physical address to the device (reduces vmexits).

V7 - Move the device's description back to the static SSDT table.
   - The GUID is store in a "hard coded" physical address and not
     in the ACPI table itself.
   - ACPI notification is triggered when the GUID is changed.

V6 - include the pre-compiled ASL file
   - remove an empty line at end of files.

V5 - Move device's description to SSDT table (dynamic).

V4 - Fix a typo in error message string.
   - Move device's description from DSDT back to SSDT table.

V3 - Remove "-uuid" command line parameter.
   - Move device's description from SSDT to DSDT table.
   - Add new "vmgenid" sysbus device.
