| * | s390x/s390-virtio-ccw: add zpcii-disable machine property | Matthew Rosato | 2022-09-26 | 1 | -1/+3 |
| | | | | | | | | | | | | | The zpcii-disable machine property can be used to force-disable the use of zPCI interpretation facilities for a VM. By default, this setting will be off for machine 7.2 and newer.

| * | s390x/pci: enable adapter event notification for interpreted devices | Matthew Rosato | 2022-09-26 | 1 | -0/+30 |
| | | | | | | | | | | | | Use the associated kvm ioctl operation to enable adapter event notification and forwarding for devices when requested. This feature will be set up with or without firmware assist based upon the 'forwarding_assist' setting.

| * | s390x/pci: enable for load/store interpretation | Matthew Rosato | 2022-09-26 | 1 | -0/+22 |
| If the ZPCI_OP ioctl reports that is is available and usable, then the underlying KVM host will enable load/store intepretation for any guest device without a SHM bit in the guest function handle. For a device that will be using interpretation support, ensure the guest function handle matches the host function handle; this value is re-checked every time the guest issues a SET PCI FN to enable the guest device as it is the only opportunity to reflect function handle changes. By default, unless interpret=off is specified, interpretation support will always be assumed and exploited if the necessary ioctl and features are available on the host kernel. When these are unavailable, we will silently revert to the interception model; this allows existing guest configurations to work unmodified on hosts with and without zPCI interpretation support, allowing QEMU to choose the best support model available.
