Re: [Xen-devel] [Q] Is qemu used when we use VTd?
Hi, Yuji

I suspect MMCONFIG is needed to access Extended PCI

can work without those access.
But we can't use full features of PCI-Express cards, right?
Yes. For example, guest software can't use AER (Advanced Error
Reporting).
To use full features of PCI-Express, we need to implement Root Port
emulator into qemu, in addition to MMCONFIG.
Thank you very much.
