...ailhouse via device tree hypervisor node - function-level PCI scan if Jailhouse is detected - MMCONFIG support for x86 guests As most changes affect x86, I would suggest to route the series also via tip after the necessary acks are collected. Changes in v4: - slit up Kconfig changes - respect pcibios_last_bus during mmconfig setup - cosmetic changes requested by Andy Changes in v3: - avoided duplicate scans of PCI functions under Jailhouse - reformated PCI_MMCONFIG condition and rephrase related commit log Changes in v2: - adjusted commit log and include ordering in patch 2 - rebased over Linus m...

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 -
