[PATCH v4 0/2] hw/virtio-pci: AER capability

Posted by Andrew Melnychenko 3 years, 5 months ago

Main motivation:
According to Microsoft driver\device certification requirements
for next version of Window Server, PCIe device must support AER.
"Windows Server PCI Express devices are required to support
Advanced Error Reporting [AER] as defined in
PCI Express Base Specification version 2.1."

AER capability for virtio-pci is disabled by default.
AER capability is only for PCI with PCIe interface on PCIe bus.
During migration - device "realize" should initialize AER
if requested by device properties.
Fixed commit message.
