[PATCH v2 0/6] jailhouse: Enhance secondary Jailhouse guest support /wrt PCI
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
