2019-02-18s390x: always provide pci supportCornelia Huck
We tried to make pci support optional on s390x in the past; unfortunately, we still require the s390 phb to be created unconditionally due to backwards compatibility issues. Instead of sinking more effort into this (including compat handling for older machines etc.) for non-obvious gains, let's just make CONFIG_PCI something that is always set on s390x. Note that you can still fence off pci for the _guest_ if you provide a cpu model without the zpci feature.

2017-09-19s390x/pci: remove idx from msix msg dataYi Min Zhao
PCIDevice pointer has been a parameter of kvm_arch_fixup_msi_route(). So we don't need to store zpci idx in msix message data to find out the specific zpci device. Instead, we could use pci device id to find its corresponding zpci device.

2017-08-30s390x: chsc nt2 events are pci-onlyCornelia Huck
The nt2 event class is pci-only - don't look for events if pci is not in the active cpu model. Reviewed-by: Thomas Huth <thuth@redhat.com> Acked-by: Christian Borntraeger <borntraeger@de.ibm.com> Signed-off-by: Cornelia Huck <cohuck@redhat.com>

Some non-pci code calls into zpci code. Provide some stubs for builds without pci. Reviewed-by: Thomas Huth <thuth@redhat.com> Acked-by: Christian Borntraeger <borntraeger@de.ibm.com> Acked-by: Halil Pasic <pasic@linux.vnet.ibm.com> Signed-off-by: Cornelia Huck <cohuck@redhat.com>
