[qemu-s390x] [PATCH v2 0/5] Retrieving zPCI specific info from QEMU

[Pierre Morel]

This patch implement the QEMU part to retrieve ZPCI specific
information from the host.
The Linux part has been posted on a separate patch on the LKML.
  
Subject: [PATCH 0/4] Retrieving zPCI specific info with VFIO
Message-Id: <address@hidden>
  
We use the PCI VFIO interface to retrieve ZPCI specific information
from the host with a ZPCI specific device region.
 
The retrieval is done only once per function and function group
during the plugging of the device.
The guest's requests are filled with shadow values we keep for
the duration of the device remains plugged.

Still there are some values we need to virtualize, like
the UID and FID of the zPCI function, and we currently
only allow the refresh bit for the zPCI group flags.

Note that we export the CLP specific definitions in a dedicated
file for clarity.
