This patch set adds support for passing a GUID to Windows guests. It is a
re-implementation of previous patch sets written by Igor Mammedov et al, but
this time passing the GUID data as a fw_cfg blob.
This patch set has dependencies on new guest functionality, in particular the
support for a new linker-loader command and the ability to write back data
to QEMU over a DMA link. Work is in flight in both SeaBIOS and OVMF to support
this.
v2->v3:
- Added second writeable fw_cfg for storing the VM Generaiton ID
address. This uses a new linker-loader command for instructing the
guest to write back the allocated address. A patch for SeaBIOS has been
submitted
(https://www.seabios.org/pipermail/seabios/2017-January/011079.html)
and the resulting binary will need to be pulled into QEMU once accepted.
- Setting VM Generation ID by command line or qmp/hmp now accepts an "auto"
value, whereby QEMU generates a random GUID.
- Incorporated review comments from v2 mainly around code styling and AML
syntax
- Changed to use the E05 ACPI event instead of E00
v1->v2:
- Removed "changed" boolean parameter as it is unneeded
- Added ACPI Notify logic
- Style changes to pass checkpatch.pl
- Added support for dynamic sysbus to pc_piix boards
Ben Warren (4):
ACPI: Add a function for building named qword entries
linker-loader: add new 'allocate and return address' cmd
ACPI: Add Virtual Machine Generation ID support
PC: Support dynamic sysbus on pc_i440fx
Igor Mammedov (2):
qmp/hmp: add query-vm-generation-id and 'info vm-generation-id'
commands
qmp/hmp: add set-vm-generation-id commands
