XenIo protocol to abstract arch specific details
|
|
|
|
The Xen implementations for the Intel and ARM archictures differ in the way
|
|
the base address of the grant table is communicated to the guest. The former
|
|
uses a virtual PCI device, while the latter uses a device tree node.
|
|
In order to allow the XenBusDxe UEFI driver to be reused for the non-PCI
|
|
Xen implementation, this abstract protocol can be installed on a handle
|
|
with the appropriate base address.
