Basic x86 support [1] for running Linux as secondary Jailhouse [2] guest is currently pending in the tip tree. This builds on top and enhances the PCI support for x86 and also ARM guests (ARM[64] does not require platform patches and works already). Key elements of this series are: - detection of Jailhouse via device tree hypervisor node - function-level PCI scan if Jailhouse is detected -
