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 -

This series add two important features. One of them changes the .ndo_tx_timeout to include an extra parameter to identify the stuck queue. Many drivers are using a nester loop to identify which queue is stooped/stucked. This is a redundant work since dev_watchdog is doing exactly the same thing. This is so interesting for other drivers to in terms of code optimization. The second part (second
