[Qemu-devel] [PATCH V16 0/4] Virtual Machine Generation ID

[Gal Hammer]

Hi,

Resending after applying changes requested from Paolo, Igor and Michael.

Thanks,

    Gal.

V16 - Remove the sysbus device and use directly a DeviceClass.
    - Device is created with -device command line parameter
    - Device have uuid and addr parameters.
    - Support for 64-bit address.
    - Shorten the ACPI device description.

V15 - Version is based on V7 ("fixed address") with new aml apis.

V13, V14 - Igor Mammedov's patches.

V12 - Fixed bios_linker_loader_add_pointer call parameters. Offset
      should be relative to the table.

V11 - Add required missing files.

V10 - Fixed typos in docs and a few clarification.

V9 - Add a unit test.
   - Rebased to version 2.2.
   - Removed hex.generated the binary files from patch.

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.
