Greetings, Following patches are intended to support SR-IOV capability in the Linux kernel. With these patches, people can turn a PCI device with the capability into multiple ones from software perspective, which will benefit KVM and achieve other purposes such as QoS, security, and etc. [PATCH 1/8 v4] PCI: define PCI resource names in a 'enum' [PATCH 2/8 v4] PCI: export __pci_read_base

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 -
